Abstract

L'invention concerne un dispositif d'absorption de choc (10) comportant au moins une poutre dite pare-chocs (12) et des platines de fixation (14-1 ; 14-2) de la poutre pare-chocs (12) au châssis d'un véhicule automobile. La poutre pare-chocs (12) comporte une partie centrale (16) et des extrémités dites de liaison (18-1 ; 18-2). La partie centrale (16) est déportée par rapport aux extrémités de liaison (18-1 ; 18-2), et les extrémités de liaison (18-1 ; 18-2) de la poutre pare-chocs (12) sont assujetties aux platines de fixation (14-1 ; 14-2) par des moyens de liaisons rapportés. Selon l'invention, le dispositif (10) comporte en outre un absorbeur de chocs dit central (22) et des absorbeurs dits de choc réparabilité (24-1 ; 24-2) et lesdits absorbeurs de choc réparabilité (24-1 ; 24-2) sont distincts des extrémités de liaison (18-1 ; 18-2) de la poutre pare-chocs (12). L'invention concerne aussi une face avant équipée d'un tel dispositif d'absorption de chocs. Application notamment au domaine automobile.
