    A FASTENING CONFIGURATION FOR ATTACHING AN ELEMENT TO ANOBJECT TECHNICAL FIELD The invention relates to a fastening configuration for attaching an element toan object according to the preamble of claim 1. The invention also relates toa vehicle.
    BACKGROUND ART Vehicles are often equipped with thermoplastic panels being producedthrough injection moulding. A common solution for attaching such an exteriorthermoplastic panel is to use clip retainers being an integrated part of thepanel, wherein a clip is attached to the clip retainer for attaching the panel in a clip being attached to a mating part on the vehicle, or other object.
    Clip retainers are used in various forms to hold the clip in a certain positionduring the assembly of a panel. Holding of clip is necessary for productioncomprising assembly. lt ensures that the assembler/operator does not need to adjust the clip position before attaching the panel to the mating part.
    The clip retainer usually comprises an elongated recess, i.e. a slot, forreceiving and retaining the clip. The clip is configured to be introduced at aninlet portion of the elongated recess and is movable along a longitudinal extension of the elongated recess. ln order make the clip stay in position usually small notches are added. Thenotches are made large enough to centre the clip along the elongatedrecess, but also small enough to allow movement along the longitudinal direction of the elongated recess.
    An example of such a prior art clip retainer is shown in fig. 1a and 1b and hasa dog-house shape and is arranged on the backside of the panel protrudingfrom the panel.
    By thus allowing movement of the clip along the longitudinal direction of theelongated recess certain expansion and shrinkage of the thermoplastic paneldue to humidity and/or change in temperature is considered. However, sucha solution may sill lead to over constrain of the thermoplastic panel, whichmay cause unwanted deformations of the panel and loss of location controlwhen fitting the panel to the mating part.
    Such a clip retainer with an elongated recess with an inlet for introducing aclip makes it possible to mount the clip up-side-down which can causedeviations / fault in production. Re-attaching the clips in the right orientationcosts time and thus money at the assembly plant.
    There is thus a need to further improve fastening configurations, e.g. clipretainers, for attaching elements such as panels to an object such as a vehicle.
    There exist many different kinds of fastening configurations for attaching different kind of elements.

According to an embodiment the element 20comprises a material with temperature and/or moisture sensitive propertiesaffecting dimensions of the element 20. The material of the element 20, e.g.a panel, is according to a variant thermoplastic, i.e. the element 20 isaccording to an embodiment a thermoplastic element, e.g. a thermoplastic panel According to an embodiment the fastening configuration 10 is an integratedpart of the element 20. Hereby easy assembly is facilitated in that only onepiece needs to be assembled to the object. According to an embodiment saidfastening configuration 10, being an integrated part of the element 20, isinjection moulded. Hereby efficient manufacturing of the fasteningconfiguration is facilitated. The fastening configuration 10 and hence theelement 20 of which the fastening configuration 10 constitutes an integratedpart is according to an embodiment made of thermoplastic material which is suitable for injection moulding.
    The fastening configuration 10 has a front side 10a, i.e. the side 10aconfigured to be facing away from the object when attached to the object.The fastening configuration 10 has a back side 10b, i.e. the side 10bconfigured to be facing the object when attached to the object.
    As illustrated in fig. 2c the element 20 has a front side 20a, i.e. the side 20aconfigured to be facing away from the object when attached to the object.The element has a back side 20b, i.e. the side 20b configured to be facingthe object when attached to the object.
    The fastening configuration 10 is arranged to protrude from the element 20.The fastening configuration 10 is arranged to protrude from a side 20c of the 11 element 20 as can be seen in fig. 2a and fig. 2b. The fastening configuration10 has a tongue-Iike shape.
    The fastening configuration 10 has an end side 10c constituting the side 10cwhere the extension of the protrusion of the fastening configuration 10 from the side of the element 10 terminates.
    The fastening configuration 10 is extending in a direction from the side of theelement 20 which is here denoted as the z-direction. The fasteningconfiguration 10 has an extension along the side 20c of the element 20 whichis here denoted as the x-direction.
    The fastening configuration 10 has a first side 10d and an opposite secondside 10d defining, i.e. delimiting, the extension of the fastening configuration10 along the side 20c of the element 20. The end side 10c, the first side 10dand the second side 10e forms a frame portion.
    The fastening configuration 10 has an extension from the back side 10b tothe front side 10a which is here denoted as the z-direction.
    The back side 10b of the fastening configuration 10 has a frame shape. Theback side 10b thus comprises or constitutes a frame portion. The fasteningconfiguration 10 has a thickness H corresponding to the extension of thefastening configuration in the z-direction.
    The fastening configuration 10 is arranged to protrude from the element 20such that the distance D from the front side 20a of the element 20 and theback side 10b of the fastening configuration 10 is longer than the height H ofthe fastening configuration 10, see fig. 2c. The extension of the fasteningconfiguration 10 in the height direction, i.e. in the direction perpendicular tothe x-direction and perpendicular to the z-direction is here denoted y- direction.
    The fastening configuration 10 has a retaining portion 12 for retaining afastening member. The frame portion formed by the sides 10c, 10d and 10e 12 is protruding from the retaining portion 12 so that a space S is formeddelimited by the sides 10c, 10d and 10e and the retaining portion 12. Theretaining portion 12 has an underside 12a configured to face away from theobject when attached to the object, and an opposite side 12b corresponding the back side 10b, see e.g. fig. 2c.
    The retaining portion 12 comprises an elongated recess 14 for receiving andretaining a fastening member 30, shown in fig. 3a-c.
    The fastening configuration 10 has an in|et portion 16 arranged in connectionto one end of the elongated recess 14 for introducing the fastening member into the elongated recess 14.
    As can be seen in fig. 2b the elongated recess 14 has a width W1. Theelongated recess 14 has a Iongitudinal extension in the x-direction and atransversal extension in the z-direction. The elongated recess 14 has a firstend 14a constituting a stop for movement of a fastening member in thelongitudinal direction, i.e. x-direction and an opposite end being connected tothe in|et portion 16 so as to facilitate introduction of a fastening member intothe elongated recess. The elongated recess 14 has a first long side 14bfacing in the direction of the element 20 and an opposite second long side14c facing the end side 10c of the fastening configuration 10.
    The in|et portion 16 has a first recess portion 16a extending along the secondside 10e between the underside 12a of the retaining portion 12 and the frontside 10a. The first recess portion 16a has a width W2 which is greater thanthe width W1 of the elongated recess 14 as can be seen in fig. 2b.
    The in|et portion 16 has a second recess portion 16b extending from acentral portion of the first recess portion 16a to and through the side 12b. Thesecond recess portion 16b has a width W3 which is smaller than the widthW2 of the first recess portion 16a, see fig. 2c, and smaller than the width W1of the elongated recess 14 as can be seen in fig. 2b and 2c. The in|et portion16 thus has a T-shaped profile viewed from the along the second side 10e. 13 The fastening configuration comprises a stop element 18 arranged inconnection to the in|et portion 16 so as to allow the fastening member to beintroduced in only one orientation. Thus, the in|et portion 16 with the firstrecess portion 16a extending along the second side 10e between theunderside 12a of the retaining portion 12 and the front side 10a provides saidstop element 18. The stop element 18 thus constitutes the portion of thesecond side 10e between the first recess portion 16a and the front side 10a.
    The elongated recess 14 has a width W1 such that the fastening member isalso movable in the transversal direction Z of the elongated recess 14. Thefastening member is configured such that it is movable along a longitudinalextension X of the elongated recess and being prevented to be removed inthe direction Y perpendicular to the longitudinal extension X and transversalextension Z of the elongated recess 14.
    By having an elongated recess 14 with a width such that the fasteningmember is also movable in the transversal direction Z of the elongatedrecess bi-axial movement of the element 20, e.g. a panel such as athermoplastic panel, is facilitated, which improves absorption of assemblytolerances, manufacturing tolerances and thermal tolerances. This thusminimizes risk of unwanted deformations of the element when attached to theobject. This further minimizes loss of location control when fitting the element20 to the object. This also facilitates reduced tolerance requirements during manufacturing of the fastening configuration.
    The elongated recess 14 comprises a gravity trap 15 along the second longside 14c of the elongated recess 14 shaped such that the fastening memberby gravity slides to a desired position along said one long side. Hereby thefastening member is self-guided to the desired position and is kept in thedesired position during assembly, thus simplifying assembly. Thus,positioning of the fastening member is facilitated without affecting the bi-axial movement. 14 The second long side 14c has a portion with a concave shape forming thegravity trap 15 for the fastening member. Hereby efficient self-guiding andpositioning of the fastening member to a desired position is obtained.
    Fig. 3a schematically i|ustrates a perspective view, fig. 3b schematicallyi|ustrates a view from the front side, and fig. 3c schematically i|ustrates aside view of the fastening configuration 10 in fig. 2a-c retaining a fasteningmember 30 according to an embodiment of the present invention.
    According to this embodiment of the fastening configuration the fasteningmember 30 is a clip. A clip is a very efficient fastening element providingeasy assembly in that the element 20, e.g. panel, only needs to be pressedagainst a mating part of the object to which the element 20 is intended to beattached. The clip is configured to be attached to a mating part of a clip joint.
    The fastening member 30 has a foot portion 32 arranged for retaining thefastening member 30 in the elongated recess 14 and on the opposite side afastening portion 34 arranged to protrude from the fastening configuration 10and the element 20. The fastening member 30 comprises an intermediateportion 36 arranged between the foot portion 32 and the fastening portion 34.
    The foot portion 32 has a width W4 which is greater than the width W1 of theelongated recess 14 for retaining the fastening member, i.e. for preventingthe fastening member 30 to be removed in the direction Y perpendicular tothe longitudinal extension X and transversal extension Z of the elongatedrecess 14, see fig. 3b. The foot portion 32 has a width W4 which is smallerthan the width W2 of the first recess portion 16a of the inlet portion 16 forallowing introduction of the foot portion 32 through the first recess portion16a, see fig. 3b.
    The fastening portion 34 has a portion 34a facing the retaining portion 12which has a width W5 which is greater than the width W1 of the elongatedrecess 14 for retaining the fastening member, i.e. for preventing the fasteningmember 30 to be removed/moved in the direction Y perpendicular to the longitudinal extension X and transversal extension Z of the elongated recess14, see fig. 3b.
    The intermediate portion 36 has a width W6 which is smaller than the widthW3 of the second recess portion 16b of the in|et portion 16 for allowingintroduction of the intermediate portion 36 through the second recess portion16b, see fig. 3c and fig. 2c.
    The fastening configuration 10 is arranged to attach the element 20 to theobject by means of the fastening member 30 so as to support the element20. The fastening member 30 is thus arranged to be fastened at said objectso as to support the element 20. The fastening member 30 is arranged to befastened to a mating part at the object so as to provide a fastening joint forsupporting the element, e.g. a panel.
    As can be seen in fig. 3c, the stop element 18 arranged in connection to thein|et portion 16 of the elongated recess will allow the fastening member 30 tobe introduced in only one orientation. Hereby assembly is simplified in thatthe fastening member 30 cannot be mounted in the wrong way to thefastening configuration 10. Thus, it is not possible to mount the fasteningmember 30, e.g. a clip which is the case in fig. 3a-c, up-side-down whereindeviations / fault in production can be avoided. Thus, unnecessary time dueto re-attaching the fastening members 30 in the right orientation can beavoided, wherein time and thus costs are saved.
    As described in connection to fig. 2a-c the elongated recess 14 has a widthW1 such that the fastening member 30 is movable in the elongated recess 14along both the longitudinal direction X and the transversal direction Z of theelongated recess 14. The fastening member 30 is thus a separate part whichis received by the fastening configuration 10 during assembly prior toattaching the element 20 to the object. The fastening member is preferably aclip. 16 As explained above the fastening member 30 is thus configured such that itis movable along the longitudinal extension and transversal direction of theelongated recess 14 and being prevented to be removed in the direction Yperpendicular to the Iongitudinal and transversal extension of the elongated recess 14.
    By having an elongated recess 14 with a width such that the fasteningmember 30 is also movable in the transversal direction of the elongatedrecess bi-axial movement of the element 20, e.g. a panel such as athermoplastic panel, is facilitated, which improves absorption of assemblytolerances, manufacturing tolerances and thermal tolerances. This thusminimizes risk of unwanted deformations of the element 20 when attached tothe object. This further minimizes loss of location control when fitting theelement 20 to the object. This also facilitates reduced tolerance requirements during manufacturing of the fastening configuration 10.
    As described in connection to fig. 2a-c the fastening configuration 10comprises a gravity trap 15 along the second long side 14c of the elongatedrecess shaped such that the fastening member by gravity slides to a desiredposition along said one long side. Hereby the fastening member 30 is self-guided to the desired position and is kept in the desired position duringassembly, thus simplifying assembly. ln fig. 3a and 3b the fastening member30 has been positioned within at the gravity trap in the elongated recess.Thus, positioning of the fastening member is facilitated without affecting thebi-axial movement. ln order for the gravity trap to function applying thefastening member 30 during assembly the orientation of the fasteningconfiguration 10 needs to be such that the second long side 14c with thegravity trap 15 needs to be lower level than the first long side 14b, i.e. thefastening configuration 10 needs to have an extension in the z-directionwhich have a certain angle relative to the horizontal plane. The extension in the z-direction during assembly is preferably essentially vertical. 17 Fig. 4a schematically illustrates a perspective view, fig. 4b schematicallyillustrates a view from the back side, and fig. 4c schematically illustrates aside view of a fastening configuration 110 for attaching an element 120 to anobject (not shown) according to an embodiment of the present invention.

The side of the fastening configuration 110 oppositeto the front wall 110e is open, i.e. provides an opening O. The opening isintended for facilitating removal of a tool part/mould part, sometimes calledslider, after an injection moulding. 19 The front wall 110e is extending in a direction along the element 120 which ishere denoted as the z-direction. The side walls 110c, 110d are extending in adirection along the element 120 which is here denoted as the x-direction. Thefastening configuration 110 has an extension along the side 120c of theelement 120 which is here denoted as the x-direction. The fasteningconfiguration 110 is protruding in a direction essentially perpendicularly fromthe element 120 which is here denoted as the y-direction.
    The fastening configuration 110 has a retaining portion 112 for retaining afastening member. The retaining portion 112 is comprised by or constitutesthe roof110b. The retaining portion 112 has an underside 112a configured toface away from the object when attached to the object, see e.g. fig. 2a.
    The retaining portion 112 comprises an elongated recess 114 for receivingand retaining a fastening member 30, shown in fig. 5a-c.
    The fastening configuration 110 has an inlet portion 116 arranged inconnection to one end of the elongated recess 114 for introducing thefastening member into the elongated recess 114. The elongated recess 114has essentially the same shape and same function as the elongated recess 14 describe with reference to fig. 2a-c and 3a-c.
    As can be seen in fig. 4b the elongated recess 114 has a width W1. Theelongated recess 114 has a longitudinal extension in the x-direction and atransversal extension in the z-direction. The elongated recess 114 has a firstend 114a constituting a stop for movement of a fastening member in thelongitudinal direction, i.e. x-direction and an opposite end being connected tothe inlet portion 116 so as to facilitate introduction of a fastening member intothe elongated recess. The elongated recess 114 has a first long side 114bfacing in the direction of the element 120 and an opposite second long side114c facing the side wall 110c of the fastening configuration 110.
    The inlet portion 116 has a first recess portion 116a extending along the frontwall 110e at a distance from the element 110. The first recess portion 116a extending along the front wall 110e in the z-direction. The first recess portion116a constitutes a cut-out of transition between the front wall 110e and theroof 110b. The first recess portion 116a has a width W2 which is greater thanthe width W1 of the elongated recess 114 as can be seen in fig. 4b.
    The in|et portion 116 has a second recess portion 116b extending from acentral portion of the first recess portion 116a to and through the roof 110b.The second recess portion 116b has a width W3 which is smaller than thewidth W2 of the first recess portion 116a, see fig. 4c, and smaller than thewidth W1 of the elongated recess 114 as can be seen in fig. 4b and 4c. Thein|et portion 116 thus has a T-shaped profile viewed from the second side110e.
    The fastening configuration comprises a stop element 118 arranged inconnection to the in|et portion 116 of the elongated recess 114 so as to allowthe fastening member to be introduced in only one orientation. The front wall110e comprises or constitutes the stop element 118.
    The elongated recess 114 has a width W1 such that the fastening member isalso movable in the transversal direction Z of the elongated recess 114. Thefastening member is configured such that it is movable along a longitudinalextension X of the elongated recess and being prevented to be removed inthe direction Y perpendicular to the longitudinal extension X and transversalextension Z of the elongated recess 114.
    By having an elongated recess 114 with a width such that the fasteningmember is also movable in the transversal direction Z of the elongatedrecess bi-axial movement of the element 120, e.g. a panel such as athermoplastic panel, is facilitated, which improves absorption of assemblytolerances, manufacturing tolerances and thermal tolerances. This thusminimizes risk of unwanted deformations of the element when attached to the object. This further minimizes loss of location control when fitting the element 21 120 to the object. This also facilitates reduced tolerance requirements during manufacturing of the fastening configuration.
    The elongated recess 114 comprises a gravity trap 115 along the secondlong side 114c of the elongated recess 114 shaped such that the fasteningmember by gravity slides to a desired position along said one long side.Hereby the fastening member is self-guided to the desired position and iskept in the desired position during assembly, thus simplifying assembly.Thus, positioning of the fastening member is facilitated without affecting the bi-axial movement.
    The second long side 114c has a portion with a concave shape forming thegravity trap 115 for the fastening member. Hereby efficient self-guiding andpositioning of the fastening member to a desired position is obtained.
    Fig. 5a schematically illustrates a perspective view, fig. 5b schematicallyillustrates a view from the back side, and fig. 5c schematically illustrates aside view of the fastening configuration 110 in fig. 4a-c retaining a fasteningmember 30 according to an embodiment of the present invention.
    The fastening member 30 corresponds to the fastening member described with reference to fig. 3a-c.
    Thus, according to this embodiment of the fastening configuration thefastening member 30 is a clip. A clip is a very efficient fastening elementproviding easy assembly in that the element 120, e.g. panel, only needs to bepressed against a mating part of the object to which the element 120 isintended to be attached. The clip is configured to be attached to a mating part of a clip joint.
    The fastening member 30 has a foot portion 32 arranged for retaining thefastening member 30 in the elongated recess 114 and on the opposite side afastening portion 34 arranged to protrude from the fastening configuration110 and the element 120. The fastening member 30 comprises an 22 intermediate portion 36 arranged between the foot portion 32 and thefastening portion 34.
    The foot portion 32 has a width W4 which is greater than the width W1 of theelongated recess 114 for retaining the fastening member 30, i.e. forpreventing the fastening member 30 to be removed in the direction Yperpendicular to the longitudinal extension X and transversal extension Z ofthe elongated recess 114, see fig. 5b. The foot portion 32 has a width W4which is smaller than the width W2 of the first recess portion 116a of the in|etportion 116 for allowing introduction of the foot portion 32 through the firstrecess portion 116a, see fig. 5b.
    The fastening portion 34 has a portion 34a facing the retaining portion 112which has a width W5 which is greater than the width W1 of the elongatedrecess 114 for retaining the fastening member, i.e. for preventing thefastening member 30 to be removed/moved in the direction Y perpendicularto the longitudinal extension X and transversal extension Z of the elongatedrecess 114, see fig. 5b.
    The intermediate portion 36 has a width W6 which is smaller than the widthW3 of the second recess portion 116b of the in|et portion 116 for allowingintroduction of the intermediate portion 36 through the second recess portion116b, see fig. 5c and fig. 4c.
    The fastening configuration 110 is arranged to attach the element 120 to theobject by means of the fastening member 30 so as to support the element120. The fastening member 30 is thus arranged to be fastened at said objectso as to support the element 120. The fastening member 30 is arranged tobe fastened to a mating part at the object so as to provide a fastening joint forsupporting the element, e.g. a panel.
    As can be seen in fig. 5c, the stop element 118 arranged in connection to thein|et portion 116 of the elongated recess will allow the fastening member 30to be introduced in only one orientation. 23 As described in connection to fig. 4a-c the elongated recess 114 has a widthW1 such that the fastening member 30 is movable in the elongated recess114 along both the longitudinal direction X and the transversal direction Z ofthe elongated recess 114. The fastening member 30 is thus a separate partwhich is received by the fastening configuration 110 during assembly prior toattaching the element 120 to the object. The fastening member is preferably a clip.
    As explained above the fastening member 30 is thus configured such that itis movable along the longitudinal extension and transversal direction of theelongated recess 114 and being prevented to be removed in the direction Yperpendicular to the longitudinal and transversal extension of the elongatedrecess 114.
    By having an elongated recess 114 with a width such that the fasteningmember 30 is also movable in the transversal direction of the elongatedrecess bi-axial movement of the element 120, e.g. a panel such as athermoplastic panel, is facilitated, which improves absorption of assemblytolerances, manufacturing tolerances and thermal tolerances. This thusminimizes risk of unwanted deformations of the element 120 when attachedto the object. This further minimizes loss of location control when fitting the120 to the object. This also facilitatesrequirements during manufacturing of the fastening configuration 110. element reduced tolerance As described in connection to fig. 4a-c the fastening configuration 110comprises a gravity trap 115 along the second long side 114c of theelongated recess shaped such that the fastening member by gravity slides toa desired position along said one long side. Hereby the fastening member 30is self-guided to the desired position and is kept in the desired position duringassembly, thus simplifying assembly. ln fig. 5a and 5b the fastening member30 has been positioned within at the gravity trap in the elongated recess 114.Thus, positioning of the fastening member 30 is facilitated without affecting the bi-axial movement. ln order for the gravity trap to function applying the 24 fastening member 30 during assembly the orientation of the fasteningconfiguration 110 needs to be such that the second long side 114c with thegravity trap 115 needs to be lower level than the first long side 114b, i.e. thefastening configuration 110 needs to have an extension in the z-directionwhich have a certain angle relative to the horizontal plane. The extension inthe z-direction during assembly is preferably essentially vertical.
    Above, with reference to the different embodiments of the fasteningconfiguration 10; 110; 210 illustrated in fig. 2a-c, 3a-c, 4a-c and 5a-can x-direction, a y-direction and a z-direction has been referred to when describingthe different views of the different embodiments. The x-, y- and z-directionsrefers to directions being essentially mutually perpendicular to each other inorder to describe extensions of the fastening configuration/ portions of thefastening configuration, and particularly the extension of the elongatedrecess 14; 114. The fastening configuration 10; 110and hence the element,e.g. panel, to be applied to an object such as a vehicle, is generally andnormally intended to be attached to the object, e.g. vehicle, essentiallyvertically. The fastening configuration 10; 110and hence the element, e.g.panel, to be applied to an object such as a vehicle, is generally and normallyintended to have an essentially vertical orientation during assemblyprocedure.
