Embodiment Construction

[0046] figure 1 Shown are the parts making up the front assembly comprising the bumper 50 mounted on a bumper reinforcement 30 which is itself fastened by fixing elements 61 , for example by bolts or riveting, It is secured to the longitudinal pillars of the vehicle by means of a box (crash box) 60 which is deformable in the event of a crash.

[0047] A case may also be provided in which the bumper reinforcement 30 is overmoulded on the structural part 20 , which here is formed by a rigid cross-beam bar made of steel or aluminium. A one-piece component 10 is thus obtained, which is itself fixed on the deformable box (crash box) 60 of the vehicle. The structural portion 20 generally includes a crash beam and may support an air guide, a pedestrian crash protection system, a battery charger or an electronic control unit (ECU).

[0048] figure 2 A front view of the bumper reinforcement 30 that is the subject of the invention is shown, seen from the front of the vehicle.

Abstract

Bumper reinforcement (30) produced by moulding a thermoplastic material and intended to be integrated in a motor vehicle front assembly between a bumper and a technical part. The bumper reinforcement (30) comprises at least one mounting plate (40) intended to bear at least one sensor (41), said mounting plate being formed in one piece with said bumper reinforcement (30) and connected by its perimeter (42) thereto via a fragile material bridge (43) such that, in the event of a frontal impact causing the deformation of the bumper reinforcement and impacting the mounting plate (40), the mounting plate (40) is fully or partly detached from the bumper reinforcement (30) under the effect of the rupture of the material bridge (43).

Description

technical field [0001] The invention relates to the field of motor vehicles. In particular, the invention relates to a module arranged at the front of the vehicle, between the engine assembly and the front protection. Background technique [0002] In the prior art, in particular according to document WO 2006 / 100379, vehicle front assemblies are known which comprise a technical front face supporting functional elements such as cooling systems, bumper skins or optical elements . The front subassembly includes at least one upper cross member for transmitting forces in the event of a crash to a vehicle side member arranged behind the front subassembly. [0003] French patent application 1758255, not yet published at the filing date of the present application, describes a front integral module for a motor vehicle comprising a structural part formed by beams constituting an energy-absorbing system and overmoulded on the structure One-piece semi-structural part on the permanent ...
