DETAILED DESCRIPTION OF THE INVENTION

[0019] The following achievements are examples. Although, the specification refers to one or several embodiments, it does not imply that each reference refers to the same embodiment or that the features apply only to a single embodiment. Simple features of different embodiments can also be combined to provide other embodiments.

[0020] In the following of the description, the terms up, upper, low, lower, vertical, horizontal refers to relative positions or directions when the door handle is assembled to a vehicle.

[0021] Fig.1 represents the outer side of a vehicle door handle 1 when it is assembled on a door panel 3 and Fig.2 represents an exploded view of different parts of the vehicle door handle 1. The vehicle door handle assembly 1 comprises a bowl 5 defining a recess 6 in which a switch (not represented) is arranged. The recess 6 is configured to receive the fingers of a user who wants to activate the switch. The bowl 5 is configured to be positioned in an opening 7 of the door panel 3. The vehicle door handle assembly 1 also comprises a peripheral gasket 9 arranged between the bowl 5 and the opening 7 of the door panel 3 in order to ensure waterproofness of the assembly 1. The vehicle door handle 1 also comprises a strip 11 configured to be positioned on the top part of the outer side of the bowl 5 in order to hide the interface between the bowl 5 and the door panel 3. The strip 11 is configured to be fastened to the bowl 5. The bowl 5 and the strip 11 may be made of plastics and may be painted. Furthermore, the strip 11 comprises two pins 112 configured to extend through holes 52 made in the bowl 5 and to protrude in two respective apertures 32 of the door panel 3 to ensure the positioning of the strip 11 with respect to the door panel 3 in the vertical direction when the door handle 1 is assembled to the vehicle. The pins 112 may be made in one piece with the strip 11. In order to allow the pins 112 to protrude to the apertures 32 of the door panel 3, the peripheral gasket 9 may be cut. In the present example, the peripheral gasket 9 comprises two cut-outs 92 located at the position of the pins 112 when the vehicle door handle 1 is assembled. According to an embodiment of the present invention, the pins 112 comprises a proximate part having a hook shape and forming a hook 110 of the strip 11 configured for fastening the strip 11 to the bowl 5. Fig.4 represents an enlarged view of a pin 112 comprising a hook 110. The pin 112 is positioned at the end of the hook 110 and extends perpendicularly to the plane of the strip 11. As shown in Fig.3, the strip 11 comprises a plurality of hooks 110 to ensure the fastening of the strip 11 to the bowl 5. In the present case, the strip 11 comprises five hooks 110 but a different number of hooks 110 may also be used. However, a high number of hooks 110 enables a good positioning of the strip 11 with respect to the bowl 5. The hooks 110 are configured to be introduced in slots 50 formed between a wall of the bowl 5 and the door panel 3 (or the peripheral gasket 9) by openings arranged in the bowl 5. The hooks 110 are distributed along the strip 11. The hooks 110 are oriented in the longitudinal direction of the strip 11 corresponding to a horizontal direction when assembled on the vehicle. The different hooks 110 are all directed in the same direction Thus, for the assembly of the strip 11 on the bowl 5, the hooks 110 are introduced in the openings associated with the slots 50 and the strip 11 is slid horizontally so that the extremity of the hooks 110 be positioned behind a wall of the bowl 5 forming the slot 50. These hooks 110 ensure the vertical positioning of the strip 11 with respect to the bowl 5. The pins 112 are arranged on two of the hooks 110, preferably on the two hooks 110 located closed to the ends of the strip 11. Alternatively a higher number of pins 112 may be used and the pins 112 may be located at a different location and can be distant from the hooks 110. The pins 112 are configured to protrude into apertures 32 made in the door panel 3 as represented in fig.5. The pins 112 and the apertures 32 have a complementary height so that the pins 112 enable to set the vertical position of the strip 11 with respect to the door panel 3. The apertures 32 may have a larger width to allow the pin 112 to be translated horizontally within the aperture 32. The aperture 32 may also be used for the fastening of a bracket 23 (visible in Fig.8). The pins 112 have for example a rectangular or squared cross section with an upper flat part configured to come into contact with the upper side of the aperture 32 and a lower flat section configured to come into contact with the lower side of the aperture 32. In the present case, the cross-section has a U shape with both legs of the U shape corresponding to the upper and lower flat parts and configured to extend horizontally when the vehicle is assembled but other shapes may be chosen for the cross-section of the pins 112. The height of a pins 112 matches the height of an aperture 32 and the extremity of the pins 112 may be chamfered to ease the insertion of the pin 112 in the aperture 32 of the door panel 3.

[0022] The bowl 5 and the strip 11 also comprises clipping means to block the horizontal displacement of the strip 11 when the hooks 110 and the pins 112 get in the right position (respectively within the slots 50 and within the apertures 32). In the present case, these clipping means are achieved by a lever (not represented), for example a flexible lever, arranged on the bowl 5 and a stop 111 arranged on the strip 11, the stop 111 being configured to block the translation of the strip 11 in the horizontal direction when assembled on the vehicle. The lever may be made in one piece with the bowl 5 and the stop 111 may be made in one piece with the strip 11. Alternatively, the lever could also be arranged on the strip 11 and the stop could be arranged on the bowl 5 and other configurations of clipping means may also be used. The stop 111 is positioned at an end of the strip 11 but other positions of the stop 111 may also be chosen. The pins 112 enables therefore positioning the strip 11 with respect to the door panel 3 and therefore aligning the strip to the door panel 3, especially in the vertical direction. Furthermore, such solution does not require additional parts or additional assembling steps.

[0023] The present invention also refers to a method for assembling the vehicle door handle 1 on the door panel 3.

[0024] Fig.6 is flowchart of the different steps of the method according to the invention.

[0025] The first step 101 refers to the fastening of a bracket 23 (visible in Fig.8) on the inner side of the door panel 3. The inner side corresponds to the side facing the interior of the vehicle when the vehicle is assembled.

[0026] The second step 102 refers to the fastening of the strip 11 on the bowl 5. The hooks 110 of the strip 11 are introduced within the slots 50 of the bowl 5. the strip 11 is then translated laterally to be clipped to the bowl 5.

[0027] The third step 103 refers to the positioning of the peripheral gasket 9 on the bowl 5. A footprint may be designed on the bowl 5 to ease the positioning of the peripheral gasket 9 on the bowl 5.

[0028] According to an alternate solution corresponding to step 103', the peripheral gasket 9 may be positioned on the outer side of the door panel 3 around the opening 7. The peripheral gasket 9 may comprise bumps and the door panel 3 may comprise complementary holes configured to receive the bumps to ensure the correct positioning of the peripheral gasket 9.

[0029] The fourth step 104 refers to the positioning of the set comprising the bowl 5 and the strip 11 in the opening 7 of the door panel 3, the peripheral gasket 9 being sandwiched between the bowl 5 and the outer side of the door panel 3 and the pins 112 being introduced within the apertures 32.

[0030] The fifth step 105 to the positioning of a slider 17 (visible in Fig.7 and 8) in a first slot 19 of the bowl 5 and in a second slot 21 of the bracket 23 to ensure the fastening of the bowl 5 to the bracket 23 and the compression of the peripheral gasket 9 between the bowl 5 and the door panel 3. Fig.7 represents an embodiment of the slider 17 positioned on the bowl 5. The slider 17 comprises a first hook 17a and a second hook 17b configured to be introduced in a first slot 5a and a second slot 5b of the bowl 5. Fig.8 represents the bowl 5 of Fig.7 and the bracket 23, the bowl 5 being fastened to the bracket 23 by the slider 17.
