Embodiment Construction

[0048] In this specification, the terms front, rear, upper and lower refer to front-rear, up-down directions of the apron structure, which correspond to front-rear, up-down directions of the vehicle when the apron structure is assembled into the vehicle. The X, Y and Z axes correspond respectively to the longitudinal axis (from front to rear), the transverse axis and the vertical axis of the vehicle and thus of the apron structure fitted in the vehicle.

[0049] The term "substantially parallel or perpendicular" is to be understood as forming an angle with a parallel or perpendicular direction / parallel or perpendicular plane of not more than ±10°, even not more than ±5° or not more than ±1° One direction / one plane.

[0050] The term "substantially at right angles" is understood to mean an angle between 85° and 95°, even between 89° and 91°.

[0051] figure 1 Shown is an exploded view of an apron structure 1 according to an embodiment of the present invention, said apron stru...

Abstract

The invention relates to a valance panel structure (1) including a first (10) and second shell (20) extending in a longitudinal direction and assembled such as to form a hollow body and including an inner reinforcement (30) inside said hollow body. The inner reinforcement (30) includes three planar walls (32, 34, 36) arranged two-by-two at right angles or substantially at right angles such as to form an approximately Z-shaped cross-section, a longitudinal free edge (33) of a first planar wall (32) being inserted between two assembled securing rims (16a, 22a) of the first and second shells, at least on one portion of the length of said securing rims, a third planar wall (36) which is parallel or substantially parallel to the first wall (32) being applied against the bottom wall (12) of the first shell and attached to same.

Description

technical field [0001] The invention relates to a motor vehicle skirt structure. Background technique [0002] Motor vehicles often include floors bordering door sills at the sides. Said threshold comprises an apron generally formed by two U-shaped profiles joined facing each other, one of which is arranged on the outside of the floor and the other is arranged on the inside of the floor and is connected to it. The skirt is thus a hollow body which must however be able to resist a certain number of impact types. For example, in the event of a frontal or rear impact, the skirting must be able to maintain the rescue chamber, ie the doorway area, to allow the firefighters to open the door, although considerable forces generally pass through the skirting. In the event of a side impact, such as the case of a pediment impact type, the skirt is the first area of ​​resistance encountered. It must therefore be deformable in the direction of impact in order to absorb energy and damp...
