Abstract

L'invention a pour objet une partie arrière de structure (2) de véhicule automobile. La partie arrière (2) comprend deux longerons arrière (10) supportant le poids du véhicule et qui chevauchent l'essieu arrière. Elle comprend en outre un premier (18) et un deuxième système d'absorption d'énergie de choc arrière, le deuxième système étant plus en arrière que le premier système (18). Le premier système (18) inclue des portions d'absorption d'énergie (20) s'étendant principalement longitudinalement, et qui sont chacune fixée à un des deux longerons (10) à l'aide de moyens de fixation (30) répartis le long de chaque longeron arrière (10). L'invention est dédiée aux chocs arrières à grande vitesse, par exemple d'au moins 80km/h ; dans lesquels les véhicules entrent en collision avec un désaxage.
