Embodiment Construction

[0043] figure 1 and 2 This has been described in the context of the discussion of the background art.

[0044] Figures 3 to 5 Deformation of a conventional deformable front structure of a vehicle is shown in the event of a frontal impact with full overlap or mostly full overlap. More specifically, image 3 shows the structure in the undeformed state, Figure 4 shows the structure in its deformed state after impact, and Figure 5 show the basis Figure 4 The neutral fiber (la fiber neutre) of the deformed structure.

[0045] exist image 3 Among them, the front mechanism 2 of the vehicle mainly consists of a front cross member 4 held at its two ends by two deformable profiles 6 commonly referred to as “crash boxes”. These profiles are intended to be deformed by forming folded folds, which deformation is also commonly referred to as "bottelage". The structure 2 also comprises two parallel longitudinal structural sections 8 a and 8 b supporting the deformable section 6 ...

Abstract

The invention relates to a motor vehicle structure (102) comprising two longitudinal structural profiles (108b) extending towards the front of the vehicle with mounting plates (114) at the forward ends thereof; two deformable profiles (106) extending respectively in the forward continuation of the structural profiles (108b) and fixed to the mounting plates (114); and a transverse beam (104) fixed to the forward ends of the deformable profiles (106). The structure further comprises an arm (118) fixed to the power unit (120) and extending essentially transversely (or longitudinally) as far as the rear face of the mounting plate (114) of one of the two structural profiles (108b), so as to apply to said mounting plate (114) a longitudinal and / or transverse force able to encourage outward lateral deformation of the forward end (116b) of the structural profile (108b) in the event of an impact on the transverse beam (104).

Description

technical field [0001] The invention relates to the absorption of impacts to the front of a vehicle. More particularly, the present invention relates to a vehicle front structure and a vehicle capable of absorbing a front impact. Background technique [0002] The system or device for absorbing frontal impacts of a vehicle usually consists of a cross member fastened to two compressively deformable profiles, often referred to as “crash boxes”. These deformable profiles may each comprise a fastening plate for fastening on the head of a side member of the vehicle structure. Stringers are two structural profiles that run parallel to each other along the structure of the vehicle. A deformable profile or “crash box” is provided to be deformable by forming folded folds. This deformation is also commonly referred to as "baling" because the deformed profile takes on a ring shape, much like a bundled haystack. [0003] Absorbers for frontal impacts of vehicles should satisfy a very...
