Abstract

L’invention concerne un élément absorbeur de chocs (13) pour véhicule automobile. L’élément absorbeur de chocs (13) est destiné à être assemblé sur une extrémité arrière d’un longeron latéral du véhicule automobile. L’élément absorbeur de chocs (13) comporte une jambe de force (14), un organe de fixation (15) destinée à permettre la fixation de la jambe de force (14) au longeron du véhicule automobile et un dispositif de fixation (16) destiné à permettre la fixation de la jambe de force (14) à un panneau arrière du véhicule automobile. Dans l’élément absorbeur de chocs (13) selon l’invention, la jambe de force (14) comporte un dispositif déformable – dit dispositif (18) à déformation programmée – configuré pour autoriser une dissipation d’énergie mécanique en cas de compression de ladite jambe de force (14). Figure à publier avec l’abrégé : Fig. 2The invention relates to a shock-absorbing element (13) for a motor vehicle. The shock-absorbing element (13) is intended to be assembled on a rear end of a side member of the motor vehicle. The shock-absorbing element (13) comprises a strut (14), a fixing member (15) intended to allow the strut (14) to be fixed to the side member of the motor vehicle and a fixing device (16) intended to allow the strut (14) to be fixed to a rear panel of the motor vehicle. In the shock-absorbing element (13) according to the invention, the strut (14) comprises a deformable device – called a programmed deformation device (18) – configured to allow mechanical energy dissipation in the event of compression of said strut (14). Figure to be published with the abstract: Fig. 2
