Problems solved by technology

The document does not address the issue of recoil of body parts upon impact, but concerns the breaking of brittle links after impacts of the pedestrian (pieton) type on a smaller scale and the guidance of body parts to prevent friction against other parts of the car , not to limit recoil that could cause significant damage to other body parts

Embodiment Construction

[0030] figure 1 It has been described in the introduction section.

[0031] figure 2 A motor vehicle front is schematically depicted with side wings comprising the recoil limiting device according to the invention.

[0032] Front side wing 1, illustrating a body part according to the invention, is fastened to said workpiece around the bodywork with front fastening points 3a, upper fastening points 3b and three rear fastening points 3c, the upper fastening points being substantially provided in the longitudinal direction of the side wing 1 One side, extending from front to back.

[0033] The front fixing point 3a connects the wing 1 to the shock absorber, the other points 3b and 3c connect the wing to the wing liner.

[0034] These fixing points 3a, 3b and 3c take the form of lugs so that they are not subjected to large impact forces and thus not deformed.

[0035] Repairability tests on the wing showed that it suffered damage to the door from recoil towards the door 2 . ...

Abstract

The invention relates to a bodywork element with means of limiting the intrusion of this element upon an impact therewith. This element is characterized in that it comprises means (6, 6a) of limiting the intrusion of this element (1) when this element is subjected to an impact the force of which is directed substantially parallel to the longitudinal axis of the vehicle. Application to the field of motor vehicles.

Description

technical field [0001] The invention relates to a body part with a device for limiting recoil of the body part when the body part is impacted. Background technique [0002] New protocols have been identified and Behavior of Body Parts Under Impact and new test procedures have been implemented to evaluate the behavior of body parts under standardized impacts. These tests relate in particular to so-called repairability shocks. [0003] The repairability test allows to assess the price of repairs when the tested car hits a rigid barrier at 15km / h, which also simulates what happens in a car park at 4km / h (in Europe or 8km / h in the US and Canada) shock. Such an impact on a rigid barrier during a repairability test causes non-negligible material damage, and the response of a type of automobile to the repairability test is the standard considered by the underwriter in determining the premium for this type of automobile insurance contract. [0004] These tests generally, but not ...
