Abstract

L'invention concerne un habitacle en plastique renforcé de fibre de verre (11) destiné à une automobile, qui comprend : un arceau de sécurité en U renversé (17), monté sur les châssis latéraux arrière gauche et droit (23) ; et des jambes de force gauche et droite (18), qui se déploient selon un plan incliné vers le bas depuis la partie supérieure de l'arceau de sécurité (17) et sont reliés, à leurs extrémités inférieures respectives, aux châssis latéraux arrière (23) par l'intermédiaire d'éléments de support (67) métalliques. Des amortisseurs (73) d'un dispositif de suspension arrière sont maintenus sur les éléments de support (67), lesdits éléments de support (67) pouvant par conséquent être utilisés pour maintenir fermement les deux jambes de force (18) de l'arceau de sécurité (17) et les amortisseurs (73) de la suspension arrière. Le poids de la carrosserie du véhicule peut ainsi être allégé par rapport aux cas où ces éléments sont maintenus individuellement sur les châssis latéraux arrière (23).
