• the invention relates to the field of motor vehicle body parts, more specifically openings, such as tailgates or side doors, and in particular the integration of equipment installed therein.
• a motor vehicle tailgate generally comprises an outer panel (also called outer skin) attached to an inner panel (also called lining).
• the interior panel has a first opening in the upper part of the tailgate intended to accommodate a rear window.
• this inner panel is usually provided with small recesses allowing local passage for the attachment of components.
• motor vehicle tailgates incorporate, in the lower part of the tailgate, side rear signaling lights, such as brake lights, generally a left light and a right light located symmetrically on either side. another from the tailgate.
• these two lights are located along and as close as possible to the side edges of the tailgate in order to face, in the closed position of the tailgate, the additional rear light located on the body of the vehicle.
• Such lights are currently manufactured by suppliers in the form of lighting blocks or optical blocks.
• Such optical blocks include a rear part, or casing, in which the lighting device is placed, as well as a window, also called glass, allowing light to pass through when the light is in operation.
• These two side lights are attached and mounted on the tailgate, on and by its outer face, which has many drawbacks.
• a light signature at the rear of vehicles such as continuous lighting between the side parts of the tailgate.
• a light device is also attached to the outside of the tailgate and may cause sealing problems or not be flush with the rest of the tailgate.
• tailgates can incorporate components to assist in driving (such as radars, lidars, or cameras) or allow communication (such as antennas or screens). It is advisable to integrate all of these components on the tailgate in a manner, here again, tight and flush (by means of a radome for example) with the rest of the tailgate.
• a motor vehicle tailgate comprising a technical panel (carrying a set of technical elements) attached to the lower part of the interior panel, the interior panel and the technical panel being covered with an outer tailgate skin, assembled to these by gluing.
• One solution considered was to assemble the interior panel and the exterior skin beforehand, then to integrate the support element and its equipment from the rear, i.e. on the passenger compartment side (side opposite the skin exterior), through a mounting opening located in the lower part of the interior panel.
• the object of the invention is in particular to remedy this drawback by providing a motor vehicle opening architecture making it possible to easily mount an equipment support plate between a lower part of the interior panel and the outer skin of the opening, from the vehicle interior.
• the invention relates to a motor vehicle door comprising:
• an inner panel preferably made of plastic material, provided with an upper part in which a first opening is made to accommodate a bezel and a lower part in which a second opening is made, and
• an outer skin at least partially made of plastic material, attached to the inner panel, comprising an inner surface located opposite an outer surface of the inner panel.
• the opening according to the invention further comprises:
• the inner panel is provided with guide means allowing blind assembly, that is to say assembly in a zone not accessible to the operator, through the opening of the support plate, it it is not necessary for him to have any particular experience or dexterity to insert the support plate between the outer skin and the inner panel.
• Such a solution also reduces the risk of assembly error.
• this solution allows assembly of the plate on the removable inner panel, which offers the possibility of disassembling the support plate, without disassembling the inner panel and the outer skin. This greatly facilitates the maintenance operations of the support plate and the equipment it carries.
• the guide means allow assembly of the support plate between the outer surface of the inner panel and the inner surface of the outer skin so that a side end of the plate is adjacent to a side wall of the opening. .
• the guide means are configured so that the support plate is guided between, on the one hand, an initial insertion position of the support plate in which the support plate extends in a non-parallel direction , preferably substantially perpendicular, to the general plane materialized by the second opening and, on the other hand, a final assembled position of the support plate in which the support plate extends in a direction substantially parallel to the general plane materialized by the second opening.
• At least part of the guide means is integral with the inner panel, for example molded, and is configured to receive a mounting arm of the support plate.
• the guide means comprise at least two ribs each forming a guide groove, the guide means further comprising at least two lugs, preferably interconnected by a cylindrical rod, coming from material with the mounting arm of the support plate, for example molded, and forming a pivot member having an axis of rotation around which the mounting arm of the support plate can pivot until the bracket reaches the assembled position.
• This configuration is particularly suited to the case where it is necessary to insert a side end of the support plate in an area that is difficult to access, for example at the level of the side edge of the tailgate, which it greatly facilitates. Indeed, it suffices for an operator to insert the support plate through the second opening, so that the mounting arm of the plate fits into the guide grooves formed by the ribs, and to pivot the support plate around the axis of rotation of the pivot member formed by the lugs to move the plate into the desired assembled position, such as a position in which a luminous equipment carried by the lateral end of the plate support is at the side edge of the interior panel and the side wall of the vehicle, closest to the outer skin.
• the latter may have a flared "U" shape which facilitates, initially, the entry of the lugs, then the guide in a second time within their section which narrows, until the end of the guide grooves where the mounting arm reaches the desired position to pivot the support plate.
• the support plate comprises a main body from which extends projecting the mounting arm with which came of material the lugs, said lugs being configured to fit into the guide grooves and to pivot around the axis of rotation when the mounting arm reaches the end of its travel within the guide grooves.
• the mounting arm protrudes from the main body of the support plate makes it possible to create an offset thanks to an offset axis of rotation which makes assembly more reliable because the main body of the plate includes electronic equipment and/or fragile light surfaces.
• the more fragile parts of the plate are brought into position while remaining at a distance from the other parts of the opening until reaching the assembled position.
• the support plate is made in several parts assembled together.
• the opening further comprises a trim fixed to an internal surface of the interior panel and covering the second opening.

• the integration of the device emitting and/or receiving electromagnetic radiation is greatly simplified, and the aesthetics of the vehicle is also improved because the device is no longer attached to the opening from the outside.
• It is also not necessary to provide for sealing for example around the lighting units of a lighting device, since the device can be placed directly in the dry zone of the opening delimited between the outer surface of the inner panel and the inner surface of the outer skin.
• such a solution makes it possible to dispense with the need to provide a specific lens taking into account the shape of the device since the transmission zone plays this role.
