    1 Energy-absorbing knee bolster frame for a vehicleTECHNICAL FIELD The invention relates to an energy-absorbing knee bolster frame for a vehicle. Theinvention also relates to an instrument panel for a vehicle, comprising an energy-absorbingknee bolster frame for a vehicle. I/|oreover, the invention relates to a vehicle comprising anenergy-absorbing knee bolster frame for a vehicle.
    The invention can be connected to an instrument panel, a cross bar member of aninstrument panel or the like. Although the invention will be described in relation to a car, theinvention is not restricted to this particular vehicle, but may as well be installed in other type of vehicles such as minivans, recreational vehicles, off-road vehicles, trucks, buses or the like.
    BACKGROUND ART ln the field of vehicle knee bolster devices there is an increasing demand for improvingthe functionality of the device during a crash or traffic collision in order to mitigate thecollision impacts on the knee regions of an occupant.
    Typically, a vehicle knee bolster device is arranged in a passenger compartment. As anexample, the vehicle knee bolster may be mounted to an instrument panel in an interior of thevehicle such as a car or the like in order to support the movement of the occupant's kneeupon a crash or collision. ln other words, a knee bolster device is a type of vehicle safety device designed toreduce leg injury, or more specifically to reduce collision impacts on the knee regions. To thisend, its purpose is to cushion occupants during a crash and provide support or protection totheir knees when they move forwards due to the forces caused by the collision.
    Some types of knee bolster devices are designed with the intention of supplementingthe protection of an occupant who is correctly restrained with a seat belt, while other types ofdevices are designed to support an occupant who is driving without a fastened seat belt.
    More recently, some types of vehicle knee bolster devices have been further adapted to absorb energy. As an example, the vehicle knee bolster device can be arranged and 2configured to absorb kinetic energy of the occupant's knee caused by the crash or the collisionby means of one or several energy-absorbing material elements.
    Accordingly, knee bolster devices for vehicles are increasingly complex as thedemands on the degree of absorbing energy of such systems increase.
    However, due to an increasing demand for reducing weight and size of thecomponents making up the device, while yet providing a functional reliable energy-absorbingknee bolster device, it remains a need for an improved vehicle knee bolster device. ln addition, it would be desirable to provide a knee bolster device that can bemanufactured in large scales, yet keeping the costs of manufacturing ofthe device to a minimum.
    SUMMARY OF THE INVENTION A general object ofthe present invention is to provide an improved energy-absorbingknee bolster frame for a vehicle, which is adapted to collapse in a controllable manner.
    This and other objects, which will become apparent in the following, are accomplishedby an energy-absorbing knee bolster frame for vehicle as defined in the accompanyingindependent claim. Details of some example embodiments and further optional features arerecited in the associated dependent claims.
    According to a first aspect of the present invention, there is provided an energy-absorbing knee bolster frame for a vehicle, comprising a longitudinal knee contact member, afirst energy-absorbing transverse bracket member and a second energy-absorbing transversebracket member. The first energy-absorbing transverse bracket member and the secondenergy-absorbing transverse bracket member extend in a transverse direction, respectively,and are arranged spaced apart on the longitudinal knee contact member. Further, thelongitudinal knee contact member has a knee contact surface for receiving a part of a knee ofan occupant upon a collision. The first energy-absorbing transverse bracket member has across section defining an open profile and is adapted at one end to engage with a vehicleinterior component. The first energy-absorbing transverse bracket member further comprisesa plurality of first deformation segments configured for absorbing energy generated by a kneeimpact. I/|oreover, each one ofthe deformation segments includes an opening and a corresponding pre-bend frame region arranged along a transverse length ofthe opening for 3 initiating a deformation of a corresponding deformation segment in a transverse directionwhen said knee bolster frame is subjected to a force from the knee ofthe occupant upon acollision. Analogously, the second energy-absorbing transverse bracket member has a crosssection defining an open profile and is adapted at one end to engage with the vehicle interiorcomponent. The second energy-absorbing transverse bracket member further comprises aplurality of second deformation segments configured for absorbing energy generated by aknee impact. I/|oreover, each one ofthe deformation segments includes an opening and acorresponding pre-bend frame region arranged along a transverse length of the opening forinitiating a deformation of a corresponding deformation segment in the transverse directionwhen the knee bolster frame is subjected to a force from the knee ofthe occupant upon a collision. ln this way, it becomes possible to provide an energy-absorbing knee bolster frame configured for absorbing energy generated upon and during a collision or traffic incident bythe configuration of the first energy-absorbing transverse bracket member and the secondenergy-absorbing transverse bracket member. The first energy-absorbing transverse bracketmember and the second energy-absorbing transverse bracket member absorbs energy bymeans of the arrangement of the deformation segments including the opening and thecorresponding pre-bend frame region. ln other words, the frame is based on two parts, i.e. thefirst energy-absorbing transverse bracket member and the second energy-absorbing transverse bracket member, that are configured to absorb energy during deformation.
    By the arrangement that the energy-absorbing transverse bracket members are arranged to the longitudinal knee contact member, having a knee contact surface for receiving a part of a knee of an occupant upon a collision, it becomes possible to direct (i.e. transfer) the forces generated from the collision to the energy-absorbing transverse bracket members in order to absorb the energy in an efficient manner.
    By the provision that each one ofthe deformation segments includes an opening and acorresponding pre-bend frame region arranged along a transverse length ofthe opening, itbecomes possible to initiate the deformation of a corresponding deformation segment in thetransverse direction so that the deformation of the bracket members can be controlled in an improved and simple manner, typically essentially in the transverse direction. Thus, when the 4knee bolster frame is subjected to a force from the knee ofthe occupant upon a collision, theforces are transferred to the bracket members which subsequently deforms due to the opening and the pre-bend frame region.
    To this end, the location of the pre-bend frame region provides a weakening region sothat the corresponding opening allows for a collapse of the deformation segment essentiallyalong the transverse direction ofthe deformation segment. ln other words, the location of thepre-bend frame region along a transverse length of the opening contributes to that the deformation is controllable and essentially directed in the transverse extension of the frame. ln addition, by using deformation segments defined by an opening and a pre-bend frame region, it becomes possible to allow for a simple adjustment ofthe deformation zoneprior to an installation of the energy-absorbing knee bolster frame with respect torequirements of deformation levels of the frame for a specific type of vehicle. ln other words,the energy-absorbing knee bolster frame may allow for a fine tuning of the deformation priorto installation of the frame into a vehicle in order to work efficiently for individuals of different sizes in terms of weight, length etc.
    Although the energy-absorbing knee bolster frame may be installed in vehicles havingseat belts, the frame according to example embodiments is particularly useful for vehicleswithout seat belts or in geographical regions where there are no legal jurisdictions as to driving with fastened seat belts. ln contrast to hitherto known energy-absorbing knee bolster devices typically includingmore complicated constructions, the frame according to example embodiments provides aninexpensive and simple knee bolster frame that is easy to manufacture, yet being flexible and possible to adapt according to requirements of the installation and the type of vehicle. lt is to be noted that the term ”energy-absorbing” as used herein typically refers to anenergy absorbing deformation characteristic. Thus, the example embodiments of theinvention relates to an energy-absorbing kneel bolster frame for a vehicle configured forabsorbing energy via deformation, the knee bolster frame including any one of the example embodiments and/or features as described herein. 5Typically, the term ”open profile” as used herein refers to a cross section such as U-shaped cross section, E-shaped cross section, I-shaped cross section, H-shaped cross section orthe like. ln other words, an open profile is to be distinguished from a cross section having a closed profile such as a annular shaped cross section.
    One advantage with an open profile is that the energy-absorbing transverse bracketmember can be manufactured in a simple and more cost-efficient manner in contrast to a closed profile. ln one example embodiment, the open profile is a U-shaped profile. That is, the openprofile has a first profile flange and a second profile flange extending from an intermediate member.
    A U-shaped profile provides for improved stability and robustness ofthe energy-absorbing transverse bracket member, which contributes to that the deformation of the bracket member can occur in an essentially transverse direction ofthe knee bolster frame. ln an example embodiment, any one of the pre-bend frame regions is defined by asubstantially convex shaped region as seen with respect to a plane defined by the transverse direction and a height direction. ln an example embodiment, each one ofthe plurality ofthe first deformationsegments and the plurality of the second deformation segments may comprise deformation segments having different deformation levels. ln an example embodiment, the plurality of the first deformation segments and theplurality of the second deformation segments are configured so that the deformation levels ofthe plurality of the first deformation segments and the plurality of the second deformationsegments increase for each following pair of deformation segments along the transverse direction, as seen from the longitudinal knee contact member. ln an example embodiment, each one ofthe plurality ofthe first deformationsegments and the plurality of the second deformation segments comprises at least oneadjustable deformation segment enabling an adjustment ofthe deformation level of the adjustable deformation segment. 6Typically, although not strictly necessary, the deformation level of the at least oneadjustable deformation segment is adjusted by amending the shape ofthe opening of the at least one adjustable deformation segment. ln an example embodiment, all deformation segments in the plurality of the firstdeformation segments and the plurality of the second deformation segments are adjustable deformation segments. ln an example embodiment, the energy-absorbing knee bolster frame is general U-shaped extending in the longitudinal direction, the transverse direction and in the height direction (direction Z).
    Typically, although not strictly necessary, the energy-absorbing knee bolster frame is made of steel, such as standard steel, high strength steel or stainless steel.
    The invention also relates to an instrument panel for a vehicle, wherein the instrumentpanel comprises an energy-absorbing knee bolster frame according to the aspect and/or anyone of the example embodiments as mentioned above with respect to the first aspect of the invention, i.e. the aspects relating to the energy-absorbing knee bolster frame.
    The invention also relates to a vehicle comprising an energy-absorbing knee bolsterframe according to any one ofthe aspects and/or example embodiments as mentioned abovewith respect to the first aspect of the invention, i.e. the aspects relating to the energy- absorbing knee bolster frame.
    Further features of, and advantages with, the present invention will become apparentwhen studying the appended claims and the following description. The skilled person realizethat different features of the present invention may be combined to create embodimentsother than those described in the following, without departing from the scope of the present invention.

    DETAILED DESCRIPTION OF EXAl/IPLE El/lBODll/IENTS OF THE INVENTION 8 The present invention will now be described more fully hereinafter with reference tothe accompanying drawings, in which exemplary embodiments of the invention are shown.The invention may, however, be embodied in many different forms and should not beconstrued as limited to the embodiments set forth herein; rather, these embodiments areprovided for thoroughness and completeness. Like reference characters refer to like elementsthroughout the description. The drawings are not necessarily to scale and certain features maybe exaggerated in order to better illustrate and explain the exemplary embodiments ofthepresent invention.
    Referring now to the figures and Figs. la - lc in particular, there is depicted an energy-absorbing knee bolster frame installed in vehicle. I/|ore particularly, the energy-absorbingknee bolster frame is here connected to an instrument panel 90 of the vehicle l. Typically,although not strictly required, the energy-absorbing knee bolster frame 10 is connected to theinstrument panel 90 below the steering column 92 ofthe vehicle l, as shown in fig. la.Accordingly, the instrument panel 90 is provided with an energy-absorbing knee bolster frameaccording to an example embodiment, as described hereinafter. The vehicle l (not entirelyshown) thus includes the instrument panel 90, which is provided with the energy-absorbingknee bolster frame 10. The energy-absorbing knee bolster frame 10 is described in furtherdetail below with reference to Figs. la - lc, Figs. 2a - 2b, Figs 3a - 3b and Figs. 4a - 4c.
    The vehicle l is provided in the form of a car. I/|oreover, the instrument panel 90 isarranged in a vehicle compartment of the car. The arrangement, components and functions ofthe instrument panel (sometimes denoted as the dashboard) are well-known in the art, andtherefore not further described herein. ln addition, it should be readily appreciated that aninstrument panel (sometimes denoted as a dashboard) is only one example of a suitableinstallation ofthe energy-absorbing knee bolster frame l0. ln some example embodiments,not shown, it may, however, be possible that the energy-absorbing knee bolster frame can beinstalled and arranged in other vehicle compartment members. ln addition, the energy-absorbing knee bolster frame can be arranged and installed inany type of vehicle such as a minivan, recreational vehicle, off-road vehicle, truck, bus or thelike.
    Turning now to Figs. la - lc and fig. 2a, an example embodiment ofthe energy-absorbing knee bolster frame of a vehicle is illustrated. Figs. la to lc are perspective views of the example embodiment ofthe energy-absorbing knee bolster frame according to the 9present invention, while Fig. 2a schematically illustrates further details of the energy-absorbing knee bolster frame according to one example embodiment.
    As mentioned above, the example embodiment of the energy-absorbing knee bolsterframe as shown in Figs.1a - 1b is connected to the instrument panel 90. Fig. 1b further showsthat a cover 94 may be arranged to the instrument panel in order to visually cover the energy-absorbing knee bolster frame 10, while Fig. 1c shows that the energy-absorbing knee bolsterframe may be arranged to a cross bar member 100 ofthe instrument panel 90. However, itshould be readily appreciated that this type of installation of the energy-absorbing kneebolster frame 10 to the cross bar member 100 is only one of several different possibilities onan installation ofthe frame 10 to the instrument panel 90.
    With particular reference to Fig. 2a, there is depicted a more detailed view of theexample embodiment ofthe energy-absorbing knee bolster frame 10 for a vehicle as shown inFigs. 1a - 1c. The energy-absorbing knee bolster frame is general U-shaped. ln addition, theenergy-absorbing knee bolster frame typically extends in a longitudinal direction X, atransverse direction Y and in a height direction (herein also referred to as the direction Z). ln other words, the energy-absorbing knee bolster frame here is general U-shaped,extending in the longitudinal direction X, the transverse direction Y and in the height directionZ (direction Z). lt should be readily appreciated that the energy-absorbing knee bolster framemay be installed with an inclination to a horizontal plane of the vehicle. However, in someexample embodiments, the energy-absorbing knee bolster frame may be installed in anessentially horizontal arrangement so that the transverse direction of the frame 10 isessentially parallel to the horizontal plane of the vehicle. The ultimate installation andarrangement ofthe frame 10 in a vehicle typically depends on the type of vehicle etc., thusseveral different installation modes are conceivable.
    As shown in Fig. 2a, the energy-absorbing knee bolster frame 10 comprises alongitudinal knee contact member 20, a first energy-absorbing transverse bracket member 30and a second energy-absorbing transverse bracket member 40. Further, the first energy-absorbing transverse bracket member 30 and the second energy-absorbing transverse bracketmember 40 extend in the transverse direction Y, respectively and arranged spaced apart onthe longitudinal knee contact member 20. lt is to be noted that the longitudinal knee contact member 20 typically extends in the longitudinal direction X and in the height direction Z, and further has thickness in the transverse direction Y. ln addition, the first energy-absorbing transverse bracket member 30typically extends in the longitudinal direction X, the transverse direction Y and in the heightdirection Z (direction Z). Analogously, the second energy-absorbing transverse bracketmember 40 also here extends in the longitudinal direction X, the transverse direction Y and inthe height direction Z (direction Z).
    Although not strictly required, the first energy-absorbing transverse bracket member30 and the second energy-absorbing transverse bracket member 40 are typically arrangedspaced apart on the longitudinal knee contact member 20 and at the outer regions of the kneecontact member 20, respectively, as shown in Figs. 1a - 1c and Fig. 2a. Hereby, it is believedthat the stability ofthe frame 10 may be further improved. lt is to be noted that the firstenergy-absorbing transverse bracket member 30 and the second energy-absorbing transversebracket member 40 are arranged spaced apart along the longitudinal direction X of thelongitudinal knee contact member 20, as shown in the Figures.
    Moreover, the longitudinal knee contact member 20 has a knee contact surface 22 forreceiving a part of a knee 80 of an occupant P upon a collision. As shown in Fig. 2a, the kneecontact surface ofthe knee contact member should be facing the occupant. Hence, the kneecontact surface 22 is here the outer surface ofthe knee contact member 20, as seen when theframe 10 is connected to the instrument panel 90.
    The first energy-absorbing transverse bracket member 30 has a cross section definingan open profile. ln other words, the first energy-absorbing transverse bracket member 30 hasa cross section defining an open profile as seen in the longitudinal direction X and in thedirection Z. As an example, the transverse bracket member 30 here has a U-shaped crosssection. ln other words, the first energy-absorbing transverse bracket member 30 has a U-shaped cross section defining an open profile as seen in the longitudinal direction X and in thedirection Z.
    Also, the first energy-absorbing transverse bracket member 30 is adapted at one end32 to engage with a vehicle interior component 100. As mentioned above, the vehicle interiorcomponent may for instance be a cross bar member 100 of an instrument panel 90.Alternatively, the vehicle interior component may refer to the instrument panel itself.
    The first energy-absorbing transverse bracket member 30 further comprises a pluralityof first deformation segments 34A-N configured for absorbing energy generated by a knee impact. As shown in e.g. Fig. 2a, and also in Fig. 2b, each one ofthe deformation segments 1134A-N includes an opening 35A-N and a corresponding pre-bend frame region 36A-N arrangedalong a transverse length ofthe opening for initiating a deformation of a correspondingdeformation segment in a transverse direction Y when the knee bolster frame 10 is subjectedto a force from the knee 80 ofthe occupant P upon a collision.
    Accordingly, the each deformation segment of the plurality of the first deformationsegments is configured for absorbing energy by means of an opening and a corresponding pre-bend frame region arranged along a transverse length ofthe opening, which may also begleaned from Fig. 3b.
    The first energy-absorbing transverse bracket member 30 may typically be adapted atone end 32 to engage with the vehicle interior component 100, such as a cross bar member ofan instrument panel 90, by means of screws or welding.
    Optional, although not strictly required, each one ofthe deformation segments 34A-Nmay include additional openings 39A-N and corresponding pre-bend frame regions 36A'-N'arranged along a transverse length ofthe opening for initiating a deformation of acorresponding deformation segment in a transverse direction Y when the knee bolster frame10 is subjected to a force from the knee 80 ofthe occupant P upon a collision. Further to benoted, the configuration and amount of openings and pre-bend region for each deformationsegment may vary depending on the situation, the purpose and the function ofthe energy-absorbing transverse bracket member. As shown in the figures, in one example embodiment,each deformation segment here comprises a set of three openings.
    Analogously, as shown in e.g. Fig. 2a, the second energy-absorbing transverse bracketmember 40 here has a cross section defining an open profile. ln other words, the secondenergy-absorbing transverse bracket member 40 has a cross section defining an open profileas seen in the longitudinal direction X and in the direction Z. As an example, the secondtransverse bracket member 40 here has a U-shaped cross section. ln other words, the secondenergy-absorbing transverse bracket member 40 has a U-shaped cross section defining anopen profile as seen in the longitudinal direction X and in the direction Z.
    Also, the second energy-absorbing transverse bracket member 40 is adapted at oneend 42 to engage with the vehicle interior component 100. The second energy-absorbingtransverse bracket member 40 further comprises a plurality of second deformation segments44A-N configured for absorbing energy generated by the knee impact. As shown in e.g. Fig. 2a, and also in Fig. 2b, each one ofthe deformation segments 44A-N includes an opening 45A-N 12and a corresponding pre-bend frame region 46A-N arranged along a transverse length oftheopening for initiating a deformation of a corresponding deformation segment in thetransverse direction Y when the knee bolster frame 10 is subjected to a force from the knee 80ofthe occupant P upon a collision.
    Accordingly, the each deformation segment ofthe plurality ofthe second deformationsegments is configured for absorbing energy by means of an opening and a corresponding pre-bend frame region arranged along a transverse length ofthe opening.
    The second energy-absorbing transverse bracket member 40 may typically be adaptedat one end 42 to engage with the vehicle interior component 100, such as a cross bar memberof an instrument panel 90, by means of screws or welding.
    Optional, although not strictly required, each one ofthe deformation segments 44A-Nmay include additional openings 49A-N and corresponding pre-bend frame regions 46A'-N'arranged along a transverse length ofthe opening for initiating a deformation of acorresponding deformation segment in a transverse direction Y when the knee bolster frame10 is subjected to a force from the knee 80 ofthe occupant P upon a collision. Further to benoted, the configuration and amount of openings and pre-bend region for each deformationsegment may vary depending on the situation, the purpose and the function of the energy-absorbing transverse bracket member. lt should be readily appreciated that a collision may refer to a traffic collision, alsoknown as a motor vehicle collision, traffic accident, motor vehicle accident, car accident,automobile accident, road traffic collision, road traffic accident, wreck, car crash, or car smash.A collision typically occurs when a vehicle collides with another vehicle, pedestrian, animal,road debris, or other stationary obstruction, such as a tree or utility pole.
    A number of factors contribute to the risk of collision, including vehicle design, speedof operation, road design, road environment, driver skill and/or impairment, and driverbehaviour.
    The example embodiment of the invention provides an energy-absorbing knee bolsterframe 10 capable of mitigating the impacts from a collision by a deformation of any one of thefirst deformable transverse bracket member 30 and the second deformable transverse bracketmember 40, i.e. to absorb energy generated due to the collision via deformation. lt should bereadily appreciated that energy herein refers to the kinetic energy from the movement of the occupant due to a e.g. a collision. ln this way, it becomes possible to provide an energy- 13 absorbing knee bolster frame configured for absorbing energy generated upon and during acollision or traffic incident by the configuration of the first energy-absorbing transversebracket member and the second energy-absorbing transverse bracket member. The firstenergy-absorbing transverse bracket member and the second energy-absorbing transversebracket member absorbs energy by means of the arrangement of the deformation segmentsincluding the opening and the corresponding pre-bend frame region. ln other words, theframe is based on two parts, i.e. the first energy-absorbing transverse bracket member andthe second energy-absorbing transverse bracket member, that are configured to absorbenergy during deformation.
    By the arrangement that the energy-absorbing transverse bracket members 20 and 30are arranged to the |ongitudina| knee contact member 20, having a knee contact surface 22for receiving a part of a knee of an occupant upon a collision, it becomes possible to direct (i.e.transfer) the forces generated from the collision via the |ongitudina| knee contact member 20to the energy-absorbing transverse bracket members 20 and 30 in order to absorb the energyin an efficient manner.
    By the provision that each one ofthe deformation segments includes an opening and acorresponding pre-bend frame region arranged along a transverse length of the opening, itbecomes possible to initiate the deformation of a corresponding deformation segment in thetransverse direction so that the deformation of the bracket members can be controlled in animproved and simple manner, typically essentially in the transverse direction. Thus, when theknee bolster frame is subjected to a force from the knee of the occupant upon a collision, theforces are transferred to the bracket members 20 and 30 which subsequently deforms due tothe opening(s) and the pre-bend frame region(s).
    To this end, the location of the pre-bend frame region provides a weakening region sothat the corresponding opening allows for a collapse of the deformation segment essentiallyalong the transverse direction ofthe deformation segment. ln other words, the location of thepre-bend frame region along a transverse length of the opening contributes to that thedeformation is controllable and essentially directed in the transverse extension of the frame. ln addition, by using deformation segments defined by an opening and a pre-bendframe region, it becomes possible to allow for a simple adjustment ofthe deformation zoneprior to an installation of the energy-absorbing knee bolster frame with respect to requirements of deformation levels of the frame for a specific type of vehicle. ln other words, 14the energy-absorbing knee bolster frame may allow for a fine tuning of the deformation priorto installation of the frame into a vehicle in order to work efficiently for individuals of differentsizes in terms of weight, length etc.
    As mentioned above, and illustrated in e.g. Figs. 1c and 2a, each one of the firstdeformable transverse bracket member 30 and the second deformable transverse bracketmember 40 has an open profile in the form of a U-shaped profile. That is, the open profile ofthe first deformable transverse bracket member 30 has a first profile flange 71 and a secondprofile flange 72 extending from an intermediate member 70. Typically, the first profile flange71 and the second profile flange 72 extends from the intermediate member 70 essentially inthe longitudinal direction X. Analogously, the open profile ofthe second deformabletransverse bracket member 40 has a first profile flange 74 and a second profile flange 75extending from an intermediate member 73. Typically, the first profile flange 74 and thesecond profile flange 75 extends from the intermediate member 73 essentially in thelongitudinal direction X. A U-shaped profile provides for improved stability and robustness ofthe energy-absorbing transverse bracket member, which contributes to that the deformationof the bracket member can occur essentially in the transverse direction Y of the knee bolsterframe 10.
    Typically, although not strictly required, the pre-bend frame regions 36A-N, 46A-N isdefined by a substantially convex shaped region as seen with respect to a plane defined by thetransverse direction Y and the direction Z, which is illustrated e.g. in Fig 2b. The pre-bendregion may be obtained in manufacturing of the bracket member by bending a part of thebracket member. However, it is conceivable that the pre-bend frame region may be obtainedby any other suitable process available to the skilled person.
    The pre-bend frame region here forms a weakening region. That is, the pre-bend frameregion is designed and arranged to form a fragile region of the bracket member configured toinitiate the collapse of the deformation segment of the bracket member. The design,dimension and strength of the pre-bend frame region may be adapted according to thepurpose and functionality of the knee bolster frame as conceivable to the skilled person. ln addition, or alternatively (although not explicitly not shown in the Figures), a pre-bend frame region may be defined by a substantially convex shaped region as seen with respect to a plane defined by the longitudinal direction X and the transverse direction Y.
    Accordingly, as shown in Figs. 2a and 2b, the first energy-absorbing transverse bracketmember 30 further comprises a plurality of first deformation segments 34A-N in the form of afirst deformation segment 34A, a second deformation segment 34B and a third deformationsegment 34C arranged along the transverse direction Y of the first transverse bracket member30. Each one of the deformation segments is configured for absorbing energy generated by aknee impact, as described above.
    As shown in e.g. Fig. 2a, and also in Fig. 2b, each one of the deformation segments34A-N further includes an opening 35A-N and a corresponding pre-bend region 36A-Narranged along a transverse length of the opening for initiating a deformation of acorresponding deformation segment in a transverse direction Y when the knee bolster frame10 is subjected to a force from the knee 80 of the occupant P upon a collision. Accordingly, thefirst deformation segment 34A further includes an opening 35A and a corresponding pre-bendregion 36A arranged along a transverse length of the opening 35A for initiating a deformationof the first deformation segment 34A in the transverse direction Y when the knee bolsterframe 10 is subjected to a force from the knee 80 ofthe occupant P upon a collision.
    Analogously, the second deformation segment 34B further includes an opening 35Band a corresponding pre-bend region 36B arranged along a transverse length of the opening35B for initiating a deformation of the second deformation segment 34B in the transversedirection Y when the knee bolster frame 10 is subjected to a force from the knee 80 of theoccupant P upon a collision. Analogously, the third deformation segment 34C further includesan opening 35C and a corresponding pre-bend region 36C arranged along a transverse lengthof the opening 35C for initiating a deformation of the third deformation segment 34C in thetransverse direction Y when the knee bolster frame 10 is subjected to a force from the knee 80ofthe occupant P upon a collision. lt should also be readily appreciated that although the example embodiment herein isillustrated by transverse bracket members including three deformation segments,respectively, the energy-absorbing knee bolster frame may be provided with transversebracket members including two deformation segments, respectively.
    Similar to the configuration of the first energy-absorbing transverse bracket member30, the second energy-absorbing transverse bracket member 40 further comprises a plurality of second deformation segments 44A-N in the form of a first deformation segment 44A, a second deformation segment 44B and a third deformation segment 44C arranged along the 16transverse direction Y of the second transverse bracket member 40. Each one of thedeformation segments is configured for absorbing energy generated by a knee impact.
    As shown in e.g. Fig. 2a, and also in Fig. 2b, each one of the deformation segments44A-N further includes an opening 45A-N and a corresponding pre-bend region 46A-Narranged along a transverse length of the opening for initiating a deformation of acorresponding deformation segment in the transverse direction Y when the knee bolsterframe 10 is subjected to a force from the knee 80 of the occupant P upon a collision.Accordingly, the first deformation segment 44A further includes an opening 45A and acorresponding pre-bend region 46A arranged along a transverse length of the opening 45A forinitiating a deformation of the first deformation segment 44A in the transverse direction Ywhen the knee bolster frame 10 is subjected to a force from the knee 80 of the occupant Pupon a collision.
    Analogously, the second deformation segment 44B further includes an opening 45Band a corresponding pre-bend region 46B arranged along a transverse length of the opening45B for initiating a deformation of the second deformation segment 44B in the transversedirection Y when the knee bolster frame 10 is subjected to a force from the knee 80 of theoccupant P upon a collision. Analogously, the third deformation segment 44C further includesan opening 45C and a corresponding pre-bend region 46C arranged along a transverse lengthof the opening 45C for initiating a deformation of the third deformation segment 44C in thetransverse direction Y when the knee bolster frame 10 is subjected to a force from the knee 80 ofthe occupant P upon a collision.
    As described above in relation to Figs. 2a and 2b, any one of the pre-bend frameregions 36A-N and 46A-N may thus be defined by a substantially convex shaped region as seenwith respect to a plane defined by the transverse direction Y and the direction Z (corresponding to height direction Z of the energy-absorbing knee bolster frame 10). ln addition, or alternatively, as shown in Figs. 1a and 2b, a pre-bend frame region 36A'-36C' or 46A' - 46C' may be defined by a substantially convex shaped region as seen with respect to a plane defined by the longitudinal direction X and in the transverse direction Y.
    Accordingly, each one of the deformation segments 34A-N may further include an opening 35A-N and a plurality of corresponding pre-bend regions 36A-N and 36A'-N' arranged 17along a transverse length of the opening for initiating a deformation of a correspondingdeformation segment in the transverse direction Y when the knee bolster frame 10 is subjected to a force from the knee 80 ofthe occupant P upon a collision.
    Analogously, each one of the deformation segments 44A-N may further include anopening 45A-N and a plurality of corresponding pre-bend regions 46A-N and 46A'-N' arrangedalong a transverse length of the opening for initiating a deformation of a correspondingdeformation segment in the transverse direction Y when the knee bolster frame 10 is subjected to a force from the knee 80 ofthe occupant P upon a collision.
    Typically, although not strictly necessary, each one of the plurality of the firstdeformation segments and the plurality of the second deformation segments comprisesdeformation segments having different deformation levels. lt should be readily appreciatedthat a deformation level is here determined by the size and shape of the opening in combination with the dimensions and the characteristics ofthe pre-bend region.
    By having deformation segments of different deformation levels, it becomes possibleto adapt the deformation and energy-absorbing characteristic of the knee bolster frame according to wishes and in view of individuals of different sizes in terms of weight, length etc.
    Thus, in the example embodiment as shown in Figs. la - 1c and 2a - 2b, the firstenergy-absorbing transverse bracket member 30 here includes a plurality of first deformationsegments comprising a first deformation segment 34A with a first deformation level, a seconddeformation segment 34B with a second deformation level, and a third deformation segment34C with a third deformation level. To this end, the first deformation level of the firstdeformation segment 34A is defined by a certain dimension of the opening 35A and the pre-bend frame region 36A, the second deformation level ofthe second deformation segment 34Bis defined by a certain dimension of the opening 35B and the pre-bend frame region 36B andthe third deformation level of the third deformation segment 34C is defined by a certain dimension ofthe opening 35C and the pre-bend frame region 36C.
    The level of deformation of the plurality of the first deformation segments typicallyincreases along the transverse direction in a direction away from the longitudinal knee contact member 20. Thus, as may be gleaned from the Figures, the dimension of the first opening is 18smaller than the dimension ofthe second opening, while the dimension ofthe second openingis smaller than the dimension of the third opening. The dimension may here typically refer to the size of the opening.
    Analogously, the second energy-absorbing transverse bracket member 40 hereincludes a plurality of second deformation segments comprising a first deformation segment44A with a first deformation level, a second deformation segment 44B with a seconddeformation level, and a third deformation segment 44C with a third deformation level. Tothis end, the first deformation level of the first deformation segment 44A is defined by acertain dimension of the opening 45A and the pre-bend frame region 46A, the seconddeformation level of the second deformation segment 44B is defined by a certain dimensionof the opening 45B and the pre-bend frame region 46B and the third deformation level of thethird deformation segment 44C is defined by a certain dimension of the opening 45C and the pre-bend frame region 46C.
    The level of deformation of the plurality of the second deformation segments typicallyincreases along the transverse direction in a direction away from the longitudinal knee contactmember 20. Thus, as may be gleaned from the Figures, the dimension of the first opening issmaller than the dimension ofthe second opening, while the dimension of the second openingis smaller than the dimension of the third opening. The dimension may here typically refer to the size of the opening.
    Thus, the plurality of the first deformation segments and the plurality of the seconddeformation segments are configured so that the deformation levels of the plurality of thefirst deformation segments and the plurality of the second deformation segments increase foreach following pair of deformation segments along the transverse direction, as seen from the longitudinal knee contact member 20. ln this context, the term ”each following pair” refers to corresponding deformationsegments of the plurality of first the deformation segments and the plurality of the seconddeformation segments. Hence, one following pair is defined by the first deformation segment34A and the first deformation segment 44A. Another following pair is defined by the second deformation segment 34B and the second deformation segment 44B. ln addition, yet another 19following pair is defined by the third deformation segment 34C and the third deformationsegment 44C.
    Optional, each one of the plurality of the first deformation segments and the pluralityof the second deformation segments may further be adjusted before installation of theenergy-absorbing knee bolster frame. The deformation segments can be adjusted in severaldifferent ways, as illustrated in Figs. 4a through 4c. Hence, turning now to Figs. 4a to 4c, insome example embodiments, each one of the plurality of the first deformation segments andthe plurality of the second deformation segments here comprises at least one adjustabledeformation segment enabling an adjustment of the deformation level of the adjustabledeformation segment. ln this manner, it becomes possible to provide a flexible knee bolsterframe in the sense that the deformation levels can be easily and quickly adaptable prior toinstallation in the vehicle so as to meet desired requirements of the vehicle. ln addition, theadjustment ofthe deformation level of the adjustable deformation segment can be performed at low cost and without advanced equipment.
    Typically, the deformation level of the at least one adjustable deformation segment isadjusted by amending the shape of the opening of the at least one adjustable deformationsegment. As an example, the adjustment of a deformation segment may be obtained byremoving a piece of material from the deformation segment. ln this respect, Fig. 4a illustratesa side view of the first example embodiment of an energy-absorbing knee bolster frame asshown in e.g. Fig. 2a and 2b, in which the transverse bracket member 30 comprises theplurality of first deformation segments 34A-34C. ln this figure, each deformation segment34A-34C includes an opening 35A-N and a corresponding pre-bend region 36A-N arrangedalong a transverse length of the opening for initiating a deformation of a correspondingdeformation segment in a transverse direction Y when the knee bolster frame 10 is subjected to a force from the knee 80 ofthe occupant P upon a collision, as mentioned above.
    The configuration of the transverse bracket member 30 as shown in Fig. 4a hereillustrates a transverse bracket member 30 prior to any adjustment of the deformation segments, and prior to installation of the knee bolster frame 10 in the vehicle.
    I/|oreover, as is clearly shown in Fig. 4a, the size of the first opening 35A is larger than the size of the second opening 35B. Herby, the deformation level of the first deformation segment 34A is less than the deformation level of the second deformation segment 34B.Analogously, the size of the second opening 35B is larger than the size of the third opening35C. Herby, the deformation level of the second deformation segment 34B is less than thedeformation level of the third deformation segment 34C. As mentioned above, this type ofconfiguration of the energy-absorbing transverse bracket member provides that the pluralityof the first deformation segments comprises deformation segments having differentdeformation levels. Analogously, if a reference is made to the second transverse bracketmember, this type of configuration of the second energy-absorbing transverse bracketmember provides that the plurality of the second deformation segments comprises deformation segments having different deformation levels.
    Turning now to Fig. 4b, a configuration of the transverse bracket member 30' (asshown in Fig. 4a) is here depicted in which the first deformation segment 34A (of the firstenergy-absorbing transverse bracket member) has been adjusted by making the first opening35A larger compared to the configuration as shown in Fig. 4a. That is, the deformation levelhas been decreased compared to the configuration of the first opening 35A as shown in Fig.4a. ln addition, the second deformation segment 34B has here been adjusted by making thesecond opening 35B larger compared to the configuration as shown in Fig. 4a. That is, thedeformation level has been decreased compared to the configuration of the second opening35B as shown in Fig. 4a. Accordingly, fig. 4b illustrates the first energy-absorbing transversebracket member 30 after an adjustment of the deformation segments, but typically prior to installation ofthe knee bolster frame 10 in the vehicle.
    Accordingly, Fig. 4b shows a configuration of the first deformation segment 34A inwhich the first deformation segment 34A and the second deformation segment 34B have beenadjusted by removing one or several pieces of material. ln other words, the energy-absorbingknee bolster frame 10 here comprises an energy-absorbing transverse bracket member 30'wherein at least one of the plurality of the first deformation segments and the plurality of thesecond deformation segments comprises at least one adjustable deformation segmentenabling an adjustment of the deformation level of the adjustable deformation segment.Further, the deformation level of the at least one adjustable deformation segment is adjusted by amending the shape of the opening ofthe at least one adjustable deformation segment. To 21this end, a deformation segment of the first energy-absorbing transverse bracket has been adjusted so as to amend the deformation level of the deformation segment. lt should be readily appreciated that the configuration and the adjustments of the firstenergy-absorbing transverse bracket 20 may likewise be applied to the second energy- absorbing transverse bracket 30.
    Hereby, it becomes possible to provide an energy-absorbing knee bolster frame, inwhich the level of deformation can be adapted according to wishes in order to better meet requirements as to user-specific energy-absorbing knee bolster frames. lt should be readily appreciated that the configuration of the first energy-absorbingtransverse bracket 20 and the second energy-absorbing transverse bracket 30, as described inrelation to Figs. 4a and 4b may be implemented or arranged in any energy-absorbing kneebolster frame as described in relation to the previous figures, e.g. Figs. la - lc, 2a - 2b and Figs. 3a - 3b.
    Typically, although not strictly required, all deformation segments in the plurality ofthe first deformation segments and the plurality of the second deformation segments areadjustable deformation segments. Also this type of configuration of the deformation segmentsmay be applied to any energy-absorbing knee bolster frame as described in relation to the previous figures, e.g. Figs. la - lc, 2a - 2b and Figs. 3a - 3b.
    Fig. 4c schematically illustrates an example embodiment of an energy-absorbing kneebolster frame as described in relation to e.g. in Fig. 2a and 2b, in which an energy-absorbingtransverse bracket member, e.g. the first energy-absorbing transverse bracket member 30, isprovided with a plurality of deformation segments comprising a first deformation segment34A and a second deformation segment 34B. This type of configuration may include any oneof the features or effects as mentioned above with respect to Figs. la - lc, 2a - 2b and Figs.4a - 4b. ln addition, in this example embodiment, the energy-absorbing transverse bracketmember can be adjusted by removing a piece of material from any one of the firstdeformation segment 34A and a second deformation segment 34B. ln addition, oralternatively, in this example embodiment, the energy-absorbing transverse bracket member can be adjusted by removing a piece of material from a third deformation segment to form an 22energy-absorbing transverse bracket member provided with a plurality of deformationsegments comprising the first deformation segment 34A and the second deformation segment34B and the third deformation segment 34C. Accordingly, there is provided an energy-absorbing transverse bracket member in which a deformation segment 34C of the energy-absorbing transverse bracket has been adjusted so as to amend the deformation level of the deformation segment.
    Furthermore, upon adjustment of the bracket member, there is provided an energy-transverse transverse bracket member wherein the plurality of the deformation segments comprises deformation segments having different deformation levels. ln all example embodiments as described in relation to the figures, it should be readilyappreciated that the ultimate dimensions of the components making up the energy-absorbingknee bolster frame are typically selected depending on the use, function and installation ofthe frame into the vehicle. Merely as an example, a thickness of the longitudinal knee contactmember in the transverse direction X may be about 1 - 2 mm. However, other dimensions areconceivable. ln addition, a length of the longitudinal knee contact member 20 in thelongitudinal direction X may be about 350 - 450 mm. Furthermore, a height ofthe longitudinalknee contact member 20 in the direction Z may be about 120 - 180 mm. The dimensions ofthe knee contact member are typically selected so as to ensure that the member is configuredto support both knees of the occupant. Hence, other dimensions are conceivable depending on the use and installation ofthe energy-absorbing knee bolster frame 10.
    As mentioned above the energy-absorbing knee bolster frame 10 according to exampleembodiments may be connected to the instrument panel 90. Alternatively, an instrumentpanel may be provided comprising an energy-absorbing knee bolster frame 10 according to any one ofthe example embodiments described herein. lt should be readily appreciated that although the description herein refers to crosssections of the energy-absorbing transverse bracket member in the form of U-shaped crosssection, the cross section may in some example embodiments be formed by another closedprofile such as an E-shaped cross section, l-shaped cross section, H-shaped cross section or the like. 23 Turning now to Figs. 3a and 3b, there is depicted an energy-absorbing knee bolsterframe 10 according to example embodiments, in which the knee bolster frame is connected tothe instrument panel and when an occupant is seated in front of the instrument panel. Fig. 3aillustrates an example embodiment of the energy-absorbing knee bolster frame 10 in anoperational state prior to a collision, while Fig. 3b illustrates the example embodiment of theenergy-absorbing knee bolster frame 10 in an operational state upon a collision, in which theenergy-absorbing knee bolster frame 10 is partly deformed due to the forces generated duringthe collision causing a knee of an occupant to move in the transverse direction Y of theenergy-absorbing knee bolster frame 10. As shown in the figures, the first deformationsegment of the energy-absorbing transverse bracket member has been deformed, as shown inFig. 4b, due to the forces from a movement of the knee of the occupant. The deformation ofthe first deformation segment 34A has been initiated due to having a deformation segmentwith a pre-bend frame region 36A and/or pre-bend frame region 36A', which here provides aweakening region of the first deformation segment (and for the entire energy-absorbingtransverse bracket member). ln addition, as the first deformation segment 34A comprises thelargest opening 35A, it is readily appreciated that the deformation initially occurs in the firstdeformation segment 34A, and then possibly continues with the second deformation segment34B and the third deformation segment 34C depending on the level of the forces from the knee of the occupant and the severity ofthe collision.
    As exemplified by the example embodiments above in relation to the Figures 1athrough 4c, it becomes possible to provide an energy-absorbing knee bolster frame configuredfor absorbing energy generated upon and during a collision or traffic incident by theconfiguration of the first energy-absorbing transverse bracket member and the secondenergy-absorbing transverse bracket member. The first energy-absorbing transverse bracketmember and the second energy-absorbing transverse bracket member absorbs energy bymeans of the arrangement ofthe deformation segments including the opening and thecorresponding pre-bend frame region. ln other words, the frame is based on two parts, i.e. thefirst energy-absorbing transverse bracket member and the second energy-absorbingtransverse bracket member, that are configured to absorb energy during deformation.
    Although the invention has been described in relation to specific combinations of components, it should be readily appreciated that the components may be combined in other 24configurations as well which is clear for the skilled person when studying the presentapplication. Thus, the above description ofthe example embodiments ofthe presentinvention and the accompanying drawings are to be regarded as a non-limiting example of theinvention and the scope of protection is defined by the appended claims. Any reference sign in the claims should not be construed as limiting the scope.
