Abstract

La présente invention concerne une structure de carrosserie arrière pour véhicules, comprenant un châssis latéral arrière et un sous-châssis arrière disposé au-dessous du châssis latéral arrière et s'étendant dans la direction avant-arrière de la carrosserie de véhicule. Le châssis latéral arrière et le sous-châssis arrière comprennent chacun une section d'absorption de charge côté châssis latéral et une section d'absorption de charge côté sous-châssis, respectivement, qui absorbent des charges de choc lorsqu'une charge de choc provenant de l'arrière de la carrosserie de véhicule agit sur le côté arrière de la carrosserie de véhicule depuis une machine auxiliaire. La section d'absorption de charge côté châssis latéral et la section d'absorption de charge côté sous-châssis sont disposées de sorte que : la section d'extrémité arrière de la section d'absorption de charge côté sous-châssis est agencée plus loin sur le côté avant de carrosserie de véhicule que la section d'extrémité arrière de la section d'absorption de charge côté châssis latéral ; et la section d'extrémité avant de la section d'absorption de charge côté sous-châssis est disposée plus loin sur le côté avant de carrosserie de véhicule que la section d'extrémité avant de la section d'absorption de charge côté châssis latéral.
