Abstract

L'invention concerne une structure de carrosserie, en particulier selon l'une quelconque des revendications précédentes, pour un véhicule à deux voies, présentant un module inférieur arrière, constitué par des longerons latéraux (7) de carrosserie qui sont reliés à l'arrière à un pare-chocs transversal (11) et auxquels est relié un cadre auxiliaire (15), qui porte un groupe moteur (17) qui est relié de manière cinématique aux roues arrière (19) du véhicule. Selon l'invention, le pare-chocs (11) est positionné de manière excentrique, c'est-à-dire décalé de la dimension verticale (Δz), par rapport aux longerons (7) de carrosserie, suite à quoi, dans le cas de collision par l'arrière, les forces (F) de collision par l'arrière sont introduites de manière excentrique dans les longerons (7). Un adaptateur (23) s'appuie avec transmission de force, directement ou indirectement, entre le pare-chocs (11) et le longeron (7) de carrosserie respectif pour la compensation de l'introduction excentrique des forces.
