Abstract

L'invention concerne un cadre auxiliaire (10), en particulier une poutre intégrale (10), pour une carrosserie d'un véhicule automobile, ayant deux traverses (20, 22) orientées au moins substantiellement dans la direction transversale (18) du véhicule et écartées l'une de l'autre dans la direction longitudinale (16) du véhicule, qui sont reliées entre elles par deux longerons (12, 14) orientés au moins substantiellement dans la direction longitudinale (16) du véhicule et écartés l'un de l'autre dans la direction transversale (18) du véhicule. Les longerons (12, 14) prennent au moins par endroits la forme de profils extrudés (32, 34) et possèdent chacun au moins une chambre (40). Au moins l'un des profils extrudés (32, 34) comporte au moins un couvercle (44, 46) grâce auquel la chambre (40) du profil extrudé (32, 34) correspondant est au moins par endroits recouverte. L'invention concerne en outre un tel cadre auxiliaire (10) dans lequel une direction de la presse d'extrusion d'au moins l'un des profils extrudés (32, 34) correspond au moins substantiellement à la direction transversale (18) du véhicule.
