    [0001] The present invention relates to a handle assembly for opening a motor vehicle door. In addition, the present invention relates to an opening of a motor vehicle, for example a door, comprising such a handle assembly.
    [0002] The present invention is applicable to the field of designing and manufacturing sashes, in particular doors, motor vehicles and their external opening controls. In particular, the present invention applies to the field of external opening controls, in particular handles, which are flush with the body trim panels, for example doors (sometimes referred to as "flush handles"). ). Motor vehicles can be passenger vehicles, commercial vehicles or industrial vehicles such as trucks. DE102004036663A1 describes a handle flush with the body, to open a door. This handle includes a housing attached to the door and a lever for gripping by a user. In use, the lever rotates relative to the housing between a closed position, where the lever is housed in the housing, an ejected position, where a portion of the lever out of the housing for gripping, and an open position, where the lever unlocks the door. This handle further comprises an ejection spring for moving the lever in the ejected position. In use, the user controls the ejection of the lever by pressing a command button. After ejecting the lever, the user must grasp the lever and rotate it from the ejected position to the open position.
    [0003] However, the user must still provide a job to tighten the ejection spring by pushing the handle from its ejected position to its closed position. In short, the user works twice to completely maneuver the handle. To reduce the work of the user, the handle DE102004036663A1 further comprises an electric actuator.
    [0004] However, such an electric actuator greatly increases the cost of the handle of DE102004036663A1. The present invention is intended in particular to solve, in whole or in part, the problems mentioned above, providing an integrally mechanical handle assembly that minimizes the work to be provided by the user.
    [0005] For this purpose, the subject of the invention is a handle assembly, for opening an opening of a motor vehicle, for example a door, the handle assembly comprising at least: a housing intended to be fixed to the opening 5 - a lever configured for gripping by a user, the lever being rotatable relative to the housing and at least between: - a closed position, in which the lever is housed totally or partially in the housing, - an ejected position wherein at least a portion of the lever is out of the housing, so that the user can exert said gripping to cause unlocking of the sash, and - an open position, in which the lever has caused the unlocking of the sash, and the opening, the handle assembly being characterized in that it further comprises an ejection mechanism connected to the lever, the ejection mechanism comprising an elastic ejection member which is resiliently deformable between: - a strongly deformed position, in which the elastic ejection member exerts an ejection force adapted to move the lever from the closed position to the ejected position, the highly deformed position being reached when the lever is in position; closed position, and - a slightly deformed position, in which the elastic ejection member exerts a negligible force, the slightly deformed position being reached when the lever is in the ejected position, the ejection mechanism comprising a deformation device configured for deforming the elastic ejection member when the lever is moved from the ejected position to the open position. In other words, the elastic ejection member is deformed as it moves from its slightly deformed position to its highly deformed position, thus when the lever is moved by the user from the ejected position to the open position. Indeed, the elastic ejection member has accumulated potential energy when it arrives in a highly deformed position, so when the lever arrives in the closed position. The elastic ejection member 3024173 3 released its potential energy when it arrives in slightly deformed position, so when the lever arrives in the ejected position. Thus, such a handle assembly minimizes the work to be provided by the user, while avoiding the use of an electric actuator or additional manual actuation. Indeed, the elastic ejection member accumulates potential energy when the user pulls on the lever to unlock the opening. The user therefore works only when unlocking the door, which is required in any set of exclusively mechanical handle. But the user has no additional work to provide, whereas a prior art handle assembly requires the user to reload an ejection spring by pushing the lever, generally from the ejected position to the closed position. In the present application, the term "effort" refers to a mechanical action, for example a force or moment, exerted or transmitted by one element on another element. In the present application, the term "negligible" qualifies an effort that is insufficient to move the lever, so a little or no effort. In the present application, the terms "strongly deformed position" and "weakly deformed position" are mutually related terms. In a highly deformed position, the elastic ejection member is more deformed than in a slightly deformed position. In a slightly deformed position, the elastic ejection member may be partially relaxed. When the elastic ejection member is partially relaxed, it can overcome the return force generated by a lever return member in the ejected position. Then the elastic ejection member is further compressed or deformed when it reaches the highly deformed position. When the lever is in the ejection position, the elastic ejection member is deformed under a load such that the cam resists the force of a lever return member in the ejected position. The cam 30 has a stop configured to stop the cam rotating to the slightly deformed position. According to a variant of the invention, the lever includes a gripping pallet. The gripping pallet may have a generally flat and elongated shape. According to a variant of the invention, the housing has a housing 35 in which is fully or partially housed the lever, the handle assembly further comprising a lid configured to completely or partially close the housing. According to one embodiment of the invention, the elastic ejection member comprises a torsion spring, preferably wound in a spiral, the torsion spring being arranged to work in torsion between the strongly deformed position and the slightly deformed position. . Thus, such a torsion spring is compact and mechanically resistant, which allows the ejection mechanism to be compact and reliable. The torsion spring may be formed by a leaf spring 10 or a round wire spring. According to one embodiment of the invention, the ejection mechanism further comprises a cam movable in rotation with respect to the lever and around a cam axis, the cam being connected to the elastic ejection member, the cam having a guide surface arranged to be in contact with the lever between the closed position and the ejected position. Thus, such a cam can transmit to the lever the ejection force exerted by the elastic ejection member. According to one embodiment of the invention, the cam comprises an eccentric element, the guide surface having generally the shape of a spiral. Thus, such an eccentric element with such a spiral-shaped guiding surface makes it possible to maximize the transmission of the ejection force. According to one embodiment of the invention, the deformation device comprises: a first toothed wheel that is integral in rotation with the cam, and a second gear wheel arranged to engage the first gear wheel, the lever being configured to drive in rotating the second gear when the lever is moved from the ejected position to the open position. Thus, when the user pulls the lever to unlock the opening, the first gear rotates, which deforms the elastic ejection member.
    [0006] According to one embodiment of the invention, the pitch diameter of the first gear wheel is substantially equal to the pitch diameter of the second gear wheel. Thus, the second gear can rotate the first gear 5 by minimizing rotational speed variations, thereby increasing the service life of the elastic ejection member. According to a variant of the invention, the pitch diameter of the first gear is substantially equal to the pitch diameter of the second gear.
    [0007] According to one embodiment of the invention, the deformation device further comprises a deformation gear arranged to engage the second gear wheel, and the lever comprises a set of teeth arranged to engage the deformation pinion so that rotation of the lever from the ejected position to the open position rotates the deformation gear, the second gear having a groove in the form of a circular arc, the deformation gear having a driving pin arranged to sliding in the groove, the groove being shaped so that: - the driving lug abuts against a first end of the groove when the lever is in the ejected position, and - the driving lug abuts against said first end the groove when the lever is in the open position. Thus, such a deformation pinion and such a set of deformation teeth make it possible to effectively turn the second gear wheel and the first gear wheel, and thus effectively deform the elastic ejection member. The deformation gear follows a circular back and forth movement in the groove. According to a variant of the invention, the deformation pinion has a pitch diameter of between 2 mm and 8 mm. According to a variant of the invention, the deformation teeth have a pitch diameter of between 10 mm and 100 mm. According to a variant of the invention, the circular arc extends over an angle of between 180 degrees and 340 degrees.
    [0008] According to one embodiment of the invention, the lever is further movable in rotation to a depressed position, the depressed position being opposed to the ejected position with respect to the closed position, and the ejection mechanism comprises furthermore, a pawl movable in rotation between: - an abutment position, in which the pawl abuts against the cam so as to prevent rotation of the cam when the lever is in the closed position, - a release position, in which the Ratchet releases the cam when the lever is in the depressed position, the ejection mechanism further comprising a return spring arranged to bias the pawl toward the stop position, the return spring preferably working in torsion. Thus, the pawl can hold the cam, so the lever, in the closed position. To control the ejection of the lever, the user presses the lever, against the return spring, until the pawl is moved to the release position. From the closed position, the lever reaches its depressed position after this support by the user on the lever. Preferably, the depressed position is close to the closed position, which minimizes the duration of the support by the user. For example, the angle between the closed position and the depressed position may be less than 10 degrees, preferably less than 5 degrees. According to one embodiment of the invention, the ejection mechanism further comprises a latch movable in rotation between: - a retaining position, in which the latch holds the lever so as to prevent rotation of the lever when the lever is in the closed position, - a release position, wherein the latch releases the lever when the lever is in the depressed position, the ejection mechanism further comprising a return spring arranged to return the latch to the retaining position, the return spring preferably working torsion Thus, such a latch prevents inadvertent ejection lever in case of impact on the opening.
    [0009] 3024173 7 When the latch is in the retaining position, the pawl is in the stop position. When the latch is in the release position, the pawl is in the release position. According to a variant of the invention, the lever comprises a shoulder portion 5 and the latch comprises a hooking portion configured to hook on the shoulder portion when the latch is in the retaining position. According to a variant of the invention, the pawl and the latch are coaxial.
    [0010] According to a variant of the invention, the axis of rotation of the latch and the pawl, the cam axis and the axis of the second gear are parallel to the axis of the lever. According to a variant of the invention, the handle assembly further comprises an elastic stud arranged in abutment against the lever so as to return the lever from the depressed position to the closed position. Thus, when the user presses the lever to command an ejection lever, the resilient pad limits the travel of the lever between the closed position and the depressed position. According to a variant of the invention, the elastic stud comprises a stud and a compression spring arranged to work in compression when the user presses against the lever, the compression spring preferably having a helical shape. According to a variant of the invention, the handle assembly further comprises a return member connected to the housing and the lever, the return member 25 being configured to exert a return force of the lever towards the closed position. Thus, such a return member eliminates the user to push the lever to its closed position, because the return member allows automatic return of the lever from the ejected position to the closed position.
    [0011] According to a variant of the invention, the return member is elastically deformable, the return member being preferably formed by a helical spring configured to work in torsion. Thus, such a return member has a high fatigue resistance, a footprint and a low cost. Alternatively to a helical spring, the return member may be formed by a spiral spring (clockwork type) working in torsion. According to a variant of the invention, the housing has a housing in which the lever is housed totally or partially, the handle assembly further comprising a lid configured to completely or partially close the housing. According to a variant of the invention, the handle assembly further comprises a hinge about which an end of an inner portion of the lever is articulated in rotation.
    [0012] According to a variant of the invention, the lever has a stop portion, and the housing has a stop portion, the stop portion being arranged to abut against the stop portion when the lever is in position d 'opening. Thus, such a stop portion and such a stop portion ensure that the lever will not dislocate, i.e., it will not exceed the open position. According to a variant of the invention, the ejection mechanism further comprises a housing configured to contain the torsion spring, the housing having an external projection arranged to cooperate with the housing so as to immobilize the casing in rotation.
    [0013] According to a variant of the invention, the external projection generally has the shape of a parallelepiped with a polygonal base, preferably with a rectangular base, and the housing has a receptacle of complementary shape to said parallelepiped. Thus, the immobilization in rotation is obtained by complementarity of shapes having no symmetry of revolution.
    [0014] According to a variant of the invention, the lever is hinged relative to the opening at least in rotation about a vertical axis when the opening is in the operating position. Alternatively, the lever is articulated relative to the opening at least one rotation about a horizontal axis when the opening is in the service position.
    [0015] According to a variant of the invention, the handle assembly further comprises i) an unlocking pinion rotatable relative to the housing, and ii) an unlocking gear for connection to an unlocking cable, a portion the unlocking gear being connected to the unlocking pinion, and the lever has an unlocking toothing arranged to engage the unlocking pinion, so that a rotation of the lever from the ejected position to the open position rotates the lever; unlocking pinion which actuates the unlocking gear.
    [0016] Thus, such an unlocking mechanism makes it possible to pull on the unlocking cable, which unlocks the lock of the opening, when the lever moves from the ejected position to the open position. According to a variant of the invention, the unlocking toothing is disposed on a first face of the lever, and the deformation toothing is disposed on a second face of the lever opposite to the first face of the lever. Thus, the handle assembly is very compact. Moreover, the present invention relates to an opening, for equipping a motor vehicle, the opening comprising: - a locking mechanism, 15 - a trim panel intended to be oriented towards the outside of the motor vehicle, the panel dressing having a hollow portion, and a handle assembly; the opening being characterized in that the handle assembly is according to the invention, and in that the handle assembly is integrally disposed in the hollow portion so that the lever is flush with the edges of the hollow portion when the lever is in the closed position. The embodiments and variants mentioned above may be taken individually or in any technically permissible combination.

Figures 1 to 34 illustrate a handle assembly 1 for opening an opening 80 of a motor vehicle not shown. The opening 80 is partially shown in Figure 4. The opening 80 is here formed by a side door of the motor vehicle. The handle assembly 1 forms an outer opening control of this side door. The handle assembly 1 is disposed on the side of the opening 80 which is intended to be oriented towards the outside of the motor vehicle.
    [0018] The handle assembly 1 comprises a housing 2 and a lever 4. In use, the housing 2 is fixed to the opening 80. The opening 80 comprises a locking mechanism, symbolized in FIG. 81, a trim panel 82 intended to be oriented towards the outside of the motor vehicle and having a hollow portion 83, as well as the handle assembly 1. The handle assembly 1 is integrally disposed in the hollow portion 83 so that the lever 4 is flush with the edges of the hollow portion 83 when the lever 4 is in the closed position. The lever 4 is configured for gripping by a user. To this end, the lever 4 has an outer portion 4.2 that the user can grasp. In contrast to the outer portion 4.2, the lever 4 has an internal portion 4.1 which is disposed in the housing 2. On the outer portion 4.2, the lever 4 includes a gripping pallet 4.3, which generally has a flat and elongated shape .
    [0019] As shown in FIG. 1, the housing 2 has a housing 3 in which the inner portion 4.1 of the lever 4 is housed. The handle assembly 1 further comprises a lid 5 which is configured to completely close the housing 3. The Lever 4 is rotatable relative to the housing 2. For this purpose, the handle assembly 1 comprises a hinge about which the end of the inner portion 4.1 of the lever 4 is articulated in rotation. In the example of the figures, this articulation is a pivot connection composed of two flanges 14 secured to the lever 4 and a lever axis 16, around which the flanges 14 pivot, thus the lever 4.
    [0020] The lever 4 is rotatable relative to the housing 2 between: - a closed position (FIGS. 11 and 15), in which the lever 4 is partially housed in the housing 2, - a depressed position (FIGS. 12 and 16), wherein the lever 4 is moved slightly inwardly of the opening 80; the depressed position is reached after the user has exerted a pressing force F12 on the lever 4 to control the ejection of the lever 4, - an ejected position (FIGS. 13 and 17), in which part of the lever 4 is output of the housing 2, so that the user can exert the grip to cause unlocking of the opening 80; the ejected position (FIGS. 3024173 13 13 and 17) is angularly opposed to the depressed position (FIGS. 12 and 16) with respect to the closed position (FIGS. 11 and 15), and - an open position (FIGS. 14 and 18), in which the lever 4 has caused the unlocking of the opening 80; the open position (FIGS. 14 and 18) is reached after the user has pulled the lever 4. In order to angularly mark the closed, depressed, ejected and open positions, the angle A11 can be set as zero angle reference. formed between respective outer faces of the lever 4 and the housing 2 when the lever is in the closed position (Figures 11 and 15). From this null angle reference 10, the following angles between the respective outer faces of the lever 4 and the housing 2 are determined: the angle A11 is equal to 0 degrees when the lever is in the closed position (FIG. 11) the angle Al2 of the depressed position is substantially equal to -2 degrees when the lever is in the depressed position (FIG. 12); the angle Al2 can be between -1 degrees and -5 degrees, the angle Al2 of the ejected position is approximately equal to +25 degrees when the lever is in the ejected position (FIG. 13), and the angle A13 the open position is approximately +35 degrees when the lever is in the open position (Fig. 14). During an opening maneuver of the opening 80, the lever 4 passes successively by 1) the closed position (FIGS. 11 and 15), 2) the depressed position (FIGS. 12 and 16), 3) the ejected position ( Figures 13 and 17) and 4) the open position (Figures 14 and 18). Thus, from the closed position 25 (FIGS. 11 and 15), the angular stroke to reach the open position (FIGS. 14 and 18) is greater than the angular stroke to reach the ejected position (FIGS. 13 and 17). The handle assembly 1 further comprises an ejection mechanism 20, which is connected to the lever 4. The mechanism has the particular function of ejecting, after user control, the lever 4, from the closed position or depressed at the ejected position (Figures 13 and 17). The ejection mechanism 20 comprises an elastic ejection member 21. In the example of Figures 1 to 34, the elastic ejection member 3024173 14 21 comprises a torsion spring wound in a spiral. The elastic ejection member 21 is elastically deformable between: a highly deformed position, in which the elastic ejection member 21 exerts an ejection force, in this case a moment M21 symbolized in FIG. 5, which is adapted to move the lever 4 from the closed position (FIGS. 11 and 15) to the ejected position (FIGS. 13 and 17), the highly deformed position being reached when the lever 4 is in the closed position (FIGS. 11 and 15), and a detent position, in which the elastic ejection member exerts a negligible force, the slightly deformed position being reached when the lever 4 is in the ejected position (FIGS. 13 and 17), in the example of FIGS. 34, the torsion spring forming the elastic ejection member 21 is arranged to work in torsion between the highly deformed position and the slightly deformed position. Between the highly deformed position and the weakly deformed position, the ejection force M21 decreases. The ejection mechanism 20 is connected to the lever 4 so as to transmit the ejection force M21 to the lever 4. The ejection force M21 may be between 0.1 Nm and 2 Nm, preferably between 0, 1 Nm and 0.5 Nm These intensities are adapted to eject most of the existing lever models. The intensity to be selected depends in particular on the mass of the lever 4. In use, the elastic ejection member 21 is deformed from its slightly deformed position to its highly deformed position when the lever 4 is moved by the user from the position ejected (FIGS. 13 and 17) at the open position (FIGS. 14 and 18). The elastic ejection member 21 has accumulated potential energy when it arrives in a highly deformed position, therefore when the lever 4 arrives in the closed position (FIGS. 11 and 15). The elastic ejection member 21 has released its potential energy when it arrives in a slightly deformed position, therefore when the lever 4 arrives in the ejected position (FIGS. 13 and 17). As shown in Figure 5, the ejection mechanism 20 further comprises a housing 19 configured to contain the torsion spring forming the elastic ejection member 21. The housing 19 has an outer projection 19.1 arranged to cooperate with the housing 2 so as to immobilize the casing 19 in rotation.
    [0021] For this purpose, the outer projection 19.1 here has the shape of a parallelepiped with a square base. The housing 2 has a receptacle 2.19 which has a shape complementary to the parallelepiped with a square base so as to immobilize in rotation the housing 19 with the housing 2 by complementarity of 5 forms. In addition, the ejection mechanism 20 comprises a cam 22 which is rotatable relative to the lever 4 and around a cam axis Z22. The cam 22 is connected to the elastic ejection member 21. In the example of FIGS. 1 to 34, the torsion spring forming the elastic ejection member 21 comprises: i) a first terminal portion which is fixed relative to the cam 22 and ii) a second end portion which is fixed relative to the housing 2 The cam 22 has a guide surface 24 which is arranged to be in contact with the lever 4 between the closed position (FIGS. 19) and the ejected position (FIGS. 13, 17 and 21). In the example of FIGS. 1 to 34, the cam 20 comprises an eccentric member and the guide surface 24 is generally in the form of a spiral. Furthermore, the cam 22 comprises a stop 23 configured to stop the cam 22 in rotation towards the closed position of the lever 4. In use, the cam 22 transmits to the lever 4, via the guide surface 24, the effort of ejection M21 which is exerted by the elastic ejection member 21 between the deformed and detent positions, so when the lever 4 is between the closed position (Figure 11) and the ejected position (Figure 13). Furthermore, the ejection mechanism 20 comprises a deformation device 30 which is configured to deform the elastic ejection member 21 when the lever 4 is moved from the ejected position (FIGS. 13 and 17) to the open position ( Figures 14 and 18). In the example of FIGS. 1 to 34, the deformation device 30 comprises a first toothed wheel 32 and a second toothed wheel 34. The pitch diameter of the first toothed wheel 32 is here equal to the pitch diameter of the second toothed wheel 34 The first toothed wheel 32 is rotationally integral with the cam 22. The first gear 32 is rotatable about the cam axis Z22. As shown in FIG. 5, the first toothed wheel 32 has a cylindrical housing 33 in which is housed the elastic ejection member 21 in the service configuration. The second gear 34 is arranged to engage the first toothed wheel 32. The lever 4 is configured to rotate the second gear 32 when the lever 4 is moved from the ejected position (FIGS. 13 and 17) to the open position. (Figures 14 and 18). In use, when the user pulls the lever 4 to unlock the opening 80, the second gear 34 drives the first gearwheel 32, so that the first gearwheel 32 rotates, causing the deformation of the gearwheel 32. Elastic ejection member 21. The deformation device 30 further comprises a deformation pinion 36 which is arranged to engage the second gear 34. In a complementary manner, the lever 4 comprises a deformation toothing 40 which is arranged in such a way as to engaging the deformation gear 36 so that a rotation of the lever 4 from the ejected position (FIGS. 13, 17, 21, 33) to the open position (FIGS. 14, 18, 22, 34) rotates the deformation gear 36. As shown in Figures 31-34, the second gear 34 has a groove 35 which has the shape of a circular arc. The deformation pinion 36 has a driving pin 37 arranged to slide in the groove 35. The groove 35 is shaped so that: the driving pin 37 abuts against a first end 35.1 of the groove when the lever 4 is in the ejected position (FIGS. 13, 17, 21, 33), and - the driving pin 37 abuts against the first end 35.1 when the lever 4 is in the open position (FIGS. 14, 18, 22, 34) . The deformation pinion 36 has a pitch diameter of between 6 and 10 mm, here equal to 6 mm. The deformation teeth 40 have a pitch diameter of between 10 and 100 mm, here equal to 100 mm. The groove 35 forms an arc extending approximately at an angle of 300 degrees. The groove has a second end 35.2 opposite the first end 35.1. In the example of FIGS. 31 to 34, the driving pin 37 is in contact with the first end 35.1 only in the ejected position (FIG. 33). This contact is maintained until the open position (Figure 34).
    [0022] Thereafter, the driving pin 37 returns to the rest position when the lever 4 returns to the closed position (FIG. 31). In the depressed position (FIG. 32), the driving pin 37 fails to touch the second end 35.2 (see FIG. 32) because there is a functional clearance.
    [0023] In use, the deformation pinion 36 and the deformation teeth 40 make it possible to turn the second gearwheel 34, thus the first toothed wheel 32, which deforms the elastic ejection member 21. The deformation gear 36 follows a circular movement back and forth in the groove 35.
    [0024] As shown in FIGS. 6, 16 and 23, the ejection mechanism 20 further comprises a pawl 42 which is rotatable between: a stop position (FIGS. 23 and 26), in which the ratchet 42 abuts against the cam 22 so as to prevent the rotation of the cam 22 when the lever 4 is in the closed position (FIGS. 11, 15, 23), - a release position (FIGS. 24 and 25), in which the pawl 42 releases the cam 22 when the lever 4 is in the depressed position (FIGS. 12, 16, 24). As shown in Figures 6, 7 and 23, the ejection mechanism 20 further comprises a return spring 44 arranged to bias the pawl 42 to the stop position (Figures 23 and 26). The return spring 44 works here in torsion. In use, the pawl 42 holds the cam 22, thus the lever 4, in the closed position (FIGS. 11, 15, 23). To control the ejection of the lever 4, the user exerts the bearing force F12 (FIG. 12) on the lever 4, against the return spring 44, until the pawl 42 is moved into the release position (Figures 24 and 25). From the closed position (FIGS. 11, 15, 23), the lever 4 reaches its depressed position (FIGS. 12, 16, 24) after exercise of this support force F12 by the user on the lever 4.
    [0025] In addition, the ejection mechanism 20 comprises a latch 46 which is rotatable between: - a retaining position (FIGS. 11 and 19), in which the latch 46 holds the lever 4 so as to prevent rotation of the lever 4 when the lever 4 is in the closed position (FIGS. 11, 19), - a release position (FIGS. 20-22), in which the latch 46 releases the lever 4 when the lever 4 is in the depressed position (FIG. , 16). The ejection mechanism 20 further comprises a return spring 48 which is arranged to return the latch 46 to the retaining position 5 (FIGS. 11 and 19). The return spring 48 works in torsion. In the example of Figures 1 to 34, the pawl 42 and the latch 46 are coaxial. The axis of rotation of the latch 46 and the pawl 42, the cam axis Z22 and the axis of the second gear 34 are parallel to the axis of the lever 4. When the latch 46 is in the retaining position (FIGS. 11 and 19), the pawl 42 is in abutment position (FIGS. 23 and 26). When the latch 46 is in the disengaged position (FIGS. 20-22), the pawl 42 is in the release position (FIGS. 24 and 25). In use, the latch 46 makes it possible to avoid inadvertent ejection of the lever 4 in the event of an impact on the opening 80. As shown in FIG. 19 or 20, the lever 4 comprises a shoulder portion 47 and the latch 46 has a hooking portion 46.1 configured to hook on the shoulder portion 47 when the latch 46 is in the retaining position (Figures 11 and 19). Furthermore, as shown in FIG. 1, the handle assembly 1 further comprises an elastic stud 50. The resilient stud 50 is arranged in abutment against the lever 4 so as to return the lever 4 from the depressed position (FIGS. 12, 16) in the closed position (Figures 14, 18). The resilient pad 50 comprises a stud 51 and a compression spring 52 arranged to work in compression when the user presses against the lever 4. The compression spring 52 here has a helical shape.
    [0026] In use, when the user presses the lever 4 to command an ejection of the lever 4, the elastic stud 50 limits the travel of the lever 4 between the closed position (FIGS. 14, 18) and the depressed position (FIGS. ). In addition, the handle assembly 1 comprises a return member 56 which is connected to the housing 2 and the lever 4. The return member 56 is configured to exert a return force of the lever 4 towards the closed position (FIGS. 14, 18). In the example of Figures 1 to 34, the return member 56 is elastically deformable and is formed by a helical spring configured to work in torsion.
    [0027] In use, the return member 56 exempts the user from pushing the lever 4 towards its closed position (FIGS. 14, 18), since the return member 56 allows automatic return of the lever 4 from the ejected position ( Figures 13, 17) in the closed position (Figures 14, 18).
    [0028] As shown in Fig. 18, the lever 4 has a stop portion 4.5 and the housing 2 has a stop portion 2.5. The abutment portion 4.5 is arranged to abut against the stop portion 2.5 when the lever 4 is in the open position (Figure 18). On the other hand, as shown in FIGS. 1 and 4, the handle assembly 1 further comprises: i) an unlocking gear 60, which is rotatable relative to the housing 2, and ii) an unlocking gear 62 , which is intended to be connected to an unlocking cable 64, a part 64.1 of the unlocking gear 64 being connected to the unlocking gear 62. The lever 4 has an unlocking toothing 66 which is arranged so as to engage the gear of unlocking 60, so that a rotation of the lever 4 from the ejected position (FIGS. 13 and 17) to the open position (FIGS. 14 and 18) rotates the unlocking gear 60 which actuates the unlocking gear 62. In use , the unlocking mechanism (60, 62, 64, 66) makes it possible to pull on the unlocking cable 64, which unlocks the lock (not shown) of the opening 80, when the lever moves from the ejected position (FIGS. 13 and 17) at pos open ition (Figures 14 and 18).
    [0029] Figures 35 to 43 illustrate a handle assembly 101 according to a second embodiment of the invention. Since the handle assembly 101 is similar to the handle assembly 1, the description of the handle assembly 1 given above in connection with FIGS. 1-34 can be transposed to the handle assembly. 101, with the notable exception of the differences set out below. A component of the handle assembly 101 which is identical or corresponding, in structure or function, to a component of the handle assembly 1 bears the same increased numerical reference of 100. Thus, a housing 102 is defined , a lever 104 with a pallet 104.3, a lever shaft 116, - an ejection mechanism 120 including i) an elastic ejection member 121 and ii) a cam 122, 5 - a deformation device 130 including i) a first gear 132, ii) a second gear 134 and ii) a deformation gear 36, a groove 135 guiding a drive pin 137, a deformation toothing 140, - a pawl 142 and return spring 144, a latch 146 and a return spring 148, a return member 156, an unlocking gear 162, an unlocking cable 164 and an unlocking toothing 166. Like the handle assembly 1, in the handle assembly 101, the lever 104 is rotatable relative to the b housing 102 between: - a closed position (FIGS. 36 and 40), in which the lever 104 is partially housed in the housing 102, - a depressed position (FIGS. 37 and 41), in which the lever 104 is moved slightly towards the interior of the opening 80; the depressed position is reached after the user has exerted a pressing force F112 on the lever 104 to control the ejection of the lever 104, an ejected position (FIGS. 38 and 42), in which part of the lever 104 is output from the housing 102, so that the user can exert the grip to cause unlocking of the not shown aperture, and - an open position (Figures 39 and 43), in which the lever 104 caused the unlocking of opening it; the open position (FIGS. 39 and 43) is reached after the user has pulled the lever 104. When in the operating position, the handle assembly 101 differs from the handle assembly 1 because lever axis 116, which articulates the lever 104 relative to the opening, is horizontal, while the lever axis 16, which articulates the lever 4 pivots relative to the opening 80, is vertical.
    [0030] The handle assembly 101 also differs from the handle assembly 1 since the pallet 104.3 extends parallel to the lever axis 116, while the pallet 4.3 extends perpendicularly to the lever axis 16. Of course, the present invention is not limited to the particular embodiments described in this patent application, nor to embodiments of the invention within the abilities of those skilled in the art. Other embodiments may be envisaged without departing from the scope of the invention, from any element equivalent to an element indicated in the present patent application.
