Abstract

L'invention concerne un pare-chocs de véhicule, pourvu d'un amortisseur de chocs (1) en mousse synthétique absorbant l'énergie, disposé entre l'habillage (3) extérieur et un support (4) intérieur sollicité en flexion. L'objectif de l'invention est de créer un pare-chocs satisfaisant au test de résistance aux chocs provoqués par pendule ainsi qu'un test de collision avec une jambe inférieure. A cet effet, ledit amortisseur de chocs présente au moins partiellement des ergots (2) ou des cavités (5).
