  • the first and second clips 23a and 23b also comprise clipping means 232 configured to cooperate respectively with the first and second sleeve 5a, 5b to prevent an axial displacement of the clips 23a, 23b and the associated axis 231, 231'.
  • the first clip 23a is configured for blocking the relative displacement in the lateral direction (with respect to the vehicle direction) of respectively the first handle sleeve 5a with respect to the first lever 13a and the second clip 23b is configured for blocking the relative displacement in the lateral direction of respectively the second handle sleeve 5b with respect to the second lever 13b.
  • the clipping means 232 may be made of a flexible rod with a hook at its extremal end.
  • the first lever 13a comprises a hole 131 at its extremal end for receiving the axis 231 of the first clip 23a and the second lever 13b comprises a hole 131' at its extremal end for receiving the axis 231' of the second clip 23b.
  • the first clip 23a comprise an oblong aperture 233 for receiving the first axis 231 of the first clip 23a so that the first axis may be displaced within the oblong aperture 233 as represented in fig.9a and 9b .

  • the axis 231 is therefore introduced in the portion of the oblong aperture 233 having a large height and its peripheral groove is then slid in the slot.
  • the axis 231 can then move laterally within the slot but cannot move axially.
  • the end of the slot next to the portion of large height of the oblong aperture 233 may have an even smaller height to prevent the axis from getting out of the slot so that a predetermined force needs to be apply to the axis 231 to slide it into the slot.
  • the axis 231 may be made in a different material than the rest of the first clip 23a.
  • the axis 231 may be metallic, for example made of aluminium, whereas the rest of the clip may be made of plastics.
  • the axis 231 is first positioned in the slot of the oblong aperture 233 of the first clip 23a and the first clip 23a is then positioned in the recess below the first sleeve 5a surrounding the first lever 13a, the axis 231 being configured to be positioned in the hole 131 of the first lever 13a as represented in Fig.9c .

Furthermore, the axis 231, 231' are configured to be in a range of 20° around the vertical position, for example in the vertical position when assembled to the vehicle so that the handle 5 is displaced in a range of 20° around the horizontal direction when the handle 5 is moved from the retracted position to the deployed position.
  • the vehicle door handle assembly 1 may also comprise an electrical actuator 29 (visible in Fig.6 ) such as an electrical motor 29 (visible in Fig.6 ) linked to the deformable parallelogram mechanism 13 in order to displace the handle 5 between the retracted position and the deployed position (the deployed and retracted position of the handle 5 may correspond to the deployed and retracted position of the deformable parallelogram mechanism 13).
  • the handle 5 comprises for example a command button 50 on its outer side and a push on the said command button 50 by a user leads to the transmission of a command signal towards the electrical actuator 29 to deploy or retract the handle 5.
  • the present invention also refers to a method for assembling a vehicle door handle assembly 1 on a door panel.
  • Fig.11 is a flowchart of the different steps of the method.

  • the first and second slots 4c, 4d are positioned respectively next to the two openings 4a, 4b.
  • the second step 102 refers to the deployment of the first 13a and the second 13b levers of the bracket 4 through the first 4a and the second 4b openings of the door panel skin 4.
  • Such deployment is achieved manually by rotating the screw 19 associated with the actionable arm 17 of the bracket 4 in a first rotating direction. Such rotation produces a displacement of the actionable arm 17.
  • the deformable parallelogram mechanism 13 linked to the actionable arm 17 is then led towards the deployed position so that the first 13a and second 13b levers are displaced towards the outer side of the door panel skin 4 through the openings 4a, 4b.
  • the screw 19 is rotated until it comes to a rest corresponding to the deployed position.
  • the third step 103 refers to the positioning of the handle 5 on the first 13a and second 13b levers.
  • the handle 5 is arranged so that the first sleeve 5a comes around the first lever 13a, the recess of the first sleeve 5a facing the hole 131 of the first lever 13a and so that the second sleeve 5b comes around the second lever 13b, the recess of the second sleeve 5b facing the hole 131' of the second lever 13b.
  • the fourth step 104 refers to the clipping of the handle 5 to the first 13a and the second 13b levers.
  • This step 104 comprises a first sub-step of introducing the axis 231 within the first clip 23a and more specifically the groove of the axis 231 within the slot of the first clip 23a.
  • the second sub-step refers to the introduction of the first clip 23a in the recess of the first sleeve 5a and the insertion of the axis 231 in the hole 131 arranged in the first lever 5a.
  • the third sub-step refers to the introduction of the second clip 23b in the recess of the second sleeve 5b and the insertion of the axis 231 in the hole 131' arranged in the second lever 13b.
  • the first 13a and second 13b levers and the handle 5 may comprise electrical contacts so that the command button 50 is linked electrically to the electrical actuator 29 when the handle 5 is clipped to the bracket 3.
  • the fifth step 105 refers to the positioning of the handle 5 back in the retracted position. Such positioning is obtained by rotating the screw 19 associated with the actionable arm 17 in the opposite direction.
  • the deformable parallelogram mechanism 13 is brought back to the retracted position thanks to one or several return springs. In the retracted position, the handle 5 flushes with the outer side of the door panel skin 4.
  • the use of a bracket 3 fixed directly on the door panel skin 4 and a handle 5 which is fastened to the bracket 3 from the outer side of the door panel skin 4 allow an easy and fast assembly and positioning of the door handle assembly 1.
  • the clipping of the handle 5 allows a fast and secured fastening of the handle 5 to the bracket 3.
  • the use of a deformable parallelogram mechanism 1 which can be displaced manually from a retracted position to a deployed position allowing the fixation of the handle 5 on the first 13a and second 13b levers of the bracket 3 corresponding to opposite branches of the deformable parallelogram mechanism 1 enables the fastening of the handle 5 on the bracket 3 without requiring the use of a electrical actuator which has to be supplied.
