Abstract

Titre de l'invention : ELEMENT ALLONGE DE STRUCTURE DE VEHICULE AVEC RAIDEUR CROISSANTE SELON SA LONGUEUR L’invention concerne un élément de structure (11) d’un véhicule automobile, ledit élément de structure (11) étant un élément allongé montrant deux extrémités et comprenant une première paroi (13) formant un corps creux, ledit élément de structure (11) étant remarquable en ce qu’au moins un moyen d’absorption de chocs (21) est disposé dans ledit corps creux de manière à s’étendre sur au moins une partie de la longueur dudit élément de structure (11), et en ce qu’au moins un moyen d’absorption (21) et/ou la première paroi (13) présente une raideur croissante selon sa longueur. Figure à publier avec l’abrégé : Fig. 2Title of the invention: ELONGATED ELEMENT OF VEHICLE STRUCTURE WITH INCREASING STIFFNESS ACCORDING TO ITS LENGTH The invention relates to a structural element (11) of a motor vehicle, said structural element (11) being an elongated element showing two ends and comprising a first wall (13) forming a hollow body, said structural element (11) being remarkable in that at least one shock absorbing means (21) is arranged in said hollow body so as to extend over at least part of the length of said structural element (11), and in that at least one absorption means (21) and/or the first wall (13) has an increasing stiffness along its length.
