Abstract
Description
Technical Field
[0001] This invention claims priority to French application 2006276, filed on June 16, 2020, the contents of which (text, drawings and claims) are incorporated herein by reference.
[0002] This invention relates to the field of motor vehicles, and more particularly to windows on motor vehicle doors. Background Technology
[0003] Traditionally, a vehicle door includes an outer panel in the lower part of the door and a door lining inside the door. The lining also forms the window frame. Furthermore, door fittings are arranged against the inner panel to cover and decorate the door lining.
[0004] The door fitting comprises a rigid or semi-rigid plate that is generally vertical and has an upper portion curved at approximately 180° to have an upper edge guided towards the bottom. This edge is configured to engage with the upper edge of the door lining, guided towards the top. In practice, during assembly of the fitting, after it has been placed in a near position, it moves in a translational motion guided towards the bottom and combined with rotation. This combination of movements can result in a discontinuity between the lateral edge of the fitting that adheres to the door lining and the adjacent window connection. This discontinuity creates an unsightly gap that reduces the perceived quality of the door.
[0005] Patent document EP1422095A2 describes a decorative element inserted into a window passageway in a vehicle door at its rear end. This element serves to fill the open space at the rear end of the door, where a vehicle occupant might be injured by snagging on it. Summary of the Invention
[0006] The present invention aims to overcome at least one of the aforementioned disadvantages of the prior art. More specifically, the present invention aims to improve the perceived quality of the interior of a vehicle door, and further specifically to improve the connection between the lateral edge of the fitting and the rest of the door.
[0007] The present invention aims to provide a door for a motor vehicle, the door comprising: an outer panel; a lining forming an inner panel disposed against the outer panel and a window frame; a window connector fitted onto the window frame and having a lip abutting against the window frame; and a garniture disposed against the inner panel and having a lateral edge having an upper end aligned with the lower end of the lip of the window connector; characterized in that the door further comprises: a trim piece including a lip adjacent to the lower end of the lip of the window connector and the upper end of the lateral edge of the garniture.
[0008] According to an advantageous embodiment of the invention, the lip of the trim has a lateral outer contour that is the same as the lateral outer contour of the lip of the window connector, so as to form a continuity of the outer contour of the lip.
[0009] According to an advantageous embodiment of the invention, the lower end of the lip of the window connector has a reduced section, which is covered by the lip cover of the trim piece.
[0010] According to an advantageous embodiment of the invention, the lip of the trim extends along a main direction that is vertical or inclined at less than 30° relative to the vertical direction, and extends over a length of less than or equal to 30 mm.
[0011] According to an advantageous embodiment of the invention, the decorative element further includes a support portion fixed to an inner plate located below the accessory.
[0012] According to an advantageous embodiment of the invention, the support includes a groove that covers the upper edge of the slot of the inner plate.
[0013] According to an advantageous embodiment of the invention, the lip of the decorative element is made of an elastomeric material overmolded onto a support made of a rigid plastic material.
[0014] According to an advantageous embodiment of the invention, the upper end of the lateral edge of the fitting is vertically recessed relative to the upper edge of the fitting.
[0015] According to an advantageous embodiment of the present invention, the window connection portion is a fixed window connection portion.
[0016] The present invention also aims to provide a motor vehicle comprising at least two doors with windows, characterized in that at least one of the at least two doors with windows is a door according to the present invention.
[0017] The advantage of the measures of the present invention is that they improve the perceived quality of the interior of a vehicle door. More specifically, by reducing the gap between the lip of the window connector and the upper end of the lateral edge of the fitting, the quality of the door is improved at the connection point between the lateral edge of the fitting and the window connector, regardless of the constraints on the combined translational and rotational movements of the fitting during assembly. This is especially true when the fitting has an upper profile that rises toward the rear of the vehicle (or optionally toward the front of the vehicle). This profile effectively increases the range of motion of the corresponding lateral edge during the assembly of the fitting. Attached Figure Description
