Description

Structural shelf for automobiles The present invention relates to the technical field of vehicles, particularly automobiles, and to a structural shelf that may be intended to support a seat belt winder placed inside a vehicle, particularly for rear seat passengers. In the automotive field, the rear of a vehicle consists of many elements that are interconnected and possess various roles and geometric structures. Among these elements, the inner rear wheel arch can be mentioned. The inner rear wheel arch is a metal sheet that forms a side partition positioned between the cavity intended to accommodate the vehicle's rear wheel and the interior of the vehicle, which is typically part of the passenger compartment and/or trunk. It is generally constructed from a single sheet metal panel. The integral construction of the wheel arch contributes to rigidity. This is achieved through stamping. The side of the car body is a set of fixed side elements that form the frame and constitute the door frame. Finally, the rear pillar of a vehicle is an upright section located at the rear of the vehicle's side body. These parts are joined together by an appropriate method, such as welding, for example. The resulting structure can be used to create an attachment surface. For example, FIG. 1 illustrates a support (10) for a seat belt winder (11) located in the rear area of the passenger compartment near the vertical structure of the vehicle body. The support (10) includes a base plate (12) fixed to the rear wheel arch (13) at a surface (14). The base plate (12) is fixed to the side of the vehicle body (15) at a surface (16). Thus, the base plate (12) is firmly fixed to the rear wheel arch and the vehicle body. Since the base plate (12) is fixed to the wheel arch (13) and the side of the vehicle body (15) over the entire contact surface to the base plate (12), in the example of a welded joint, the application of a weld spot around the perimeter of the contact surface is required. The support (10) includes a fixing part (17) having a surface (18) extending in a plane substantially parallel to the horizontal plane of the vehicle. The surface (18) of the fixing part (17) is fixed to the upper surface of the base plate (12). The fixed portion (17) includes a side (19) that extends substantially perpendicularly to the plane of the surface (18). The fixed portion (17) is fixed to the side of the vehicle body (15) on the surface (18). Finally, the fixed portion (17) is configured as an attachment point for attaching to the rear pillar (20) of the vehicle in the area (21). Thus, the support (10) is firmly fixed to the rear wheel arch, the side of the vehicle body, and the rear pillar, helping to reinforce the vehicle body. A winder (11) can be fixed to the side wall of the base plate (12) in a plane approximately parallel to the horizontal plane of the vehicle. In the event of a collision, the occupant restraining force applied by the seat belt is transmitted to the support (10) and distributed to the rear wheel arch, the side of the vehicle body, and the rear pillar, ensuring that the winder provides a sufficient level of restraining force. However, this type of support has several disadvantages. It consists of two parts; that is, two separate components must be manufactured and joined and fixed to the vehicle body. The contact surfaces between the two components and between the support and the body also require multiple points of fastening (e.g., welding). This makes the joining process more complex. Figure 1 described above is a schematic drawing illustrating a support for a conventional safety belt winder. FIG. 2 is a schematic diagram illustrating the layout of a shelf fixed to the rear wheel arch, side of the vehicle body, and rear pillar of a vehicle according to the present invention. FIG. 3 is a schematic drawing illustrating another drawing of a shelf according to the present invention. FIG. 4 is a schematic drawing illustrating a perspective view of a shelf according to the present invention as presented in FIG. 3. In these drawings, for clarity, the figures are not all at the same scale. Also, identical elements share the same reference numerals across the drawings. Furthermore, the terms "forward" and "rear" should be understood in relation to the general orientation of the vehicle. The term "forward" refers to the position facing the front of the vehicle in the horizontal direction. The term "rear" refers to the position facing the rear of the vehicle in the aforementioned horizontal direction. The inner rear wheel arch refers to the part that forms the side bulkhead positioned between the space for accommodating the vehicle's rear wheel and the interior of the vehicle. To simplify the expression of the term in the following text, the inner rear wheel arch is referred to as the "rear wheel arch." FIG. 1 schematically illustrates a support (10) for a conventional seat belt winder (11). This has been described above. FIG. 2 sch
