Description

Title of the invention: Mechanical reinforcement for a motor vehicle floor comprising a lip intended to support a support leg of a child seat. Technical field to which the invention relates

[0001] The present invention relates to the field of the automotive industry and, more particularly, to the field of mechanical reinforcements for a floor of a motor vehicle. Technological background

[0002] Regulations require the use of child seats to ensure the protection of children during car journeys. These seats are designed to keep children properly in place and reduce the risk of injury in the event of an accident.

[0003] There are several types of child seats, each with its own fastening system. Traditional child seats can be attached to the seat of a motor vehicle with a 3-point seat belt, which is recognized as sufficient practice with regard to European standards.

[0004] However, installing a child seat with a safety belt can be complicated and restrictive, especially when the space around the child seat is cluttered or restricted.

[0005] This is why a new fastening system called "Isofix" was proposed. This system allows for quick and easy installation of a child seat, while significantly reducing the risk of incorrect installation. The "Isofix" system uses two arms with clips at their ends. These clips are designed to engage with hooks located on the seat cushion of a motor vehicle. By attaching to these hooks, the clips secure the child seat to the vehicle seat.

[0006] The new "Isofix" systems no longer rely solely on these two anchor points and now include three anchor points, such as a support leg. More specifically, the support leg is a height-adjustable foot attached to the child seat and configured to rest against the floor of the motor vehicle. Thus, the support leg plays a crucial role in preventing the child seat from tipping forward in a collision. The support leg advantageously enhances the child's protection in the event of an accident.

[0007] However, it has been observed that the support leg of a child seat sometimes partially rests on a mechanical reinforcement present on the floor of motor vehicles. The support leg is then cantilevered over the mechanical reinforcement. of the floor, meaning the support leg is not fully supported on a stable surface. This partial support prevents the support leg from fulfilling its function, as it can tip over due to incomplete support on the mechanical reinforcement. Consequently, the support leg may not fully perform its role in stabilizing the child seat, thus compromising the child's safety in the event of an accident.

[0008] The invention aims to remedy this problem by providing a mechanical reinforcement for the floor of a motor vehicle, allowing a more secure support for a support leg of a child seat. Object of the invention

[0009] To this end, the invention proposes a mechanical reinforcement for a floor of a motor vehicle, comprising a plate delimited by a lower face and an upper face, the upper face being parallel or substantially parallel to the lower face, the mechanical reinforcement comprising a first rib forming a protrusion at the level of the upper face of the plate, the first rib extending along a first direction in order to increase the rigidity of the plate along said first direction.

[0010] The invention is remarkable in that the plate includes a first rim running along, at least partially, the first rib and in that the first rim is salient at the level of the upper face of the plate.

[0011] In other words, the invention provides a mechanical reinforcement comprising a lip that provides support for one foot of a child seat support leg. Advantageously, the mechanical reinforcement allows a child seat support leg to rest on both a first rib and a first lip to ensure better support of the child seat. Therefore, the mechanical reinforcement according to the invention prevents the support leg from cantilevering over the mechanical reinforcement. The presence of the first lip provides more secure support for the support leg on the mechanical reinforcement, so that the support leg can fully perform its function.

[0012] According to another embodiment of the invention, at the upper face of the plate, the height of a portion of the first rim is identical or substantially identical to the height of a portion of the protrusion formed by the first groove. In other words, at least a portion of a first rim and at least a portion of the first groove are of the same height or substantially the same height relative to the upper face of the plate, so as to allow for more secure support of a strut when said strut extends perpendicularly or substantially perpendicularly to the upper face of the mechanical reinforcement plate.

[0013] According to another embodiment of the invention, the height of the first rim is between 1 cm and 5 cm, preferably between 2 cm and 4 cm.

[0014] According to another embodiment of the invention, the length of the first rim is equal to or greater than 5 cm, preferably between 8 cm and 12 cm.

[0015] According to another embodiment of the invention, the smallest distance between the first rim and the first rib is less than 15 cm, preferably between 5 cm and 10 cm.

[0016] According to another embodiment of the invention, the first rim extends parallel or substantially parallel to the first rib.

[0017] According to another embodiment of the invention, the thickness of the first rim is between 1 mm and 4 mm, preferably between 1 mm and 2 mm.

[0018] According to another embodiment of the invention, the thickness of the rim is identical or substantially identical to the thickness of the plate.

[0019] Of course, the different characteristics, variants and embodiments mentioned above can be combined with each other in various ways, provided that they are not incompatible or mutually exclusive.

[0020] The invention also relates to a chassis for a motor vehicle comprising a floor, a face of the floor intended to delimit the passenger compartment of a motor vehicle, said face is opposite the lower face of a mechanical reinforcement described above.

[0021] According to another embodiment of the invention, the mechanical reinforcement is positioned on the floor so that the first rib and the first edge can serve as a support for a strut of a child seat.

[0022] The invention also relates to a motor vehicle comprising a chassis described above. Description of the figures

[0023] The invention will be better understood from the following description, which relates to preferred embodiments, given by way of non-limiting examples, and explained with reference to the accompanying schematic drawings, in which:

[0024] [Fig-1] illustrates a perspective view of an embodiment of a mechanical reinforcement according to the invention;

[0025] [Fig.2] illustrates a perspective view of the mechanical reinforcement shown in [Fig.1], serving as a support for a foot of a strut of a child seat;

[0026] [Fig.3] illustrates a perspective view of a floor of a motor vehicle comprising a mechanical reinforcement according to the invention, serving as a support for a foot of a strut of a child seat. Detailed description of the invention

[0027] As a reminder, the invention proposes a mechanical reinforcement for the floor of a motor vehicle, allowing a more secure support for a support leg of a child seat.

[0028] Figure 1 illustrates a perspective view of an example of an embodiment of a mechanical reinforcement 2 according to the invention. The mechanical reinforcement 2 consists of a plate 4 delimited by a lower face 6 and an upper face 8. The upper face 8 is parallel to the lower face 6 of the plate. The thickness of the plate 4, measured along a direction normal to the upper face 8, is between 1 mm and 2 mm. Preferably, the plate 4 is formed from metallic elements or synthetic polymers.

[0029] The mechanical reinforcement comprises a first rib 10 forming a protrusion 12 on the upper face 8 of the plate. The first rib extends along a first direction AA'. The first rib 10 is configured to increase the rigidity of the plate along the first direction AA'.

[0030] The length of the first rib 10, measured along the first direction AA', is between 10 cm and 30 cm, preferably on the order of 15 cm.

[0031] In a plane perpendicular to the first direction AA, the profile of the first rib 10 has a trapezoidal shape, the shorter base of which forms a vertex 14 parallel to the upper face 8 of the plate 4. The height of the vertex 14, measured relative to the upper face 8 of the plate, is between 1 cm and 5 cm, preferably on the order of 3 cm. The width of the vertex 14 is configured to allow partial support at one foot of a support leg of a child seat. According to the present example, the width of the vertex 14, measured along a direction normal to the first direction AA', is between 3 cm and 5 cm.

[0032] In order to provide more secure support for the foot of a support leg of a child seat, the plate 4 includes a first rim 16 running at least partially along the first rib 10, and the first rim 16 is projecting at the level of the upper face 8 of the plate.

[0033] Thus, advantageously, the mechanical reinforcement 2 allows the foot 18 of a support leg 20 of a child seat to bear simultaneously on the first rib 10 and the first rim 16, as illustrated in [Fig. 2], to ensure better support of the child seat. Consequently, the first rim 16 prevents the foot 18 of the support leg 20 from tipping off the first rib 10, by providing alternative support for said foot.

[0034] As a result, the first rim 16 of the plate allows the support leg 20 to fully play its role in stabilizing a child seat, in order to increase the safety of the child in the event of an accident.

[0035] Preferably, the height of the first rim 16 measured along a direction normal to the upper face 8 of the plate, is identical to the height of the top 14 of the first rib 10, so as to allow a more secure support of the strut 20 when said strut extends perpendicularly or substantially perpendicularly to the upper face 8 of the mechanical reinforcement plate.

[0036] Preferably, the smallest distance between the first rim 16 and the first rib 10 is less than 15 cm, preferably between 5 cm and 10 cm.

[0037] According to one embodiment, the mechanical reinforcement 2 may include a second rib 22, identical or substantially identical to the first rib 10, also extending parallel or substantially parallel to the first direction AA'.

[0038] Figure 3 illustrates a non-limiting example of the use of mechanical reinforcement 2 described above, on the floor 24 of a motor vehicle chassis. Preferably, the mechanical reinforcement 2 is positioned on a face 26 of the floor 24 intended to delimit the passenger compartment of a motor vehicle, such that the lower face 6 of the mechanical reinforcement 2 is opposite said face 26 of the floor. The mechanical reinforcement 2 is oriented so that the first rib 10 extends parallel or substantially parallel to the longitudinal direction of the chassis 28. Thus, the chassis 28 makes it possible to increase the safety of a child seat including a support leg, for the reasons mentioned above.
