Title
(EN) BUMPER, AND THE FABRICATION THEREOF
(FR) PARE-CHOCS ET SA FABRICATION
Abstract
(EN) The present invention relates to a structural beam or bumper, especially for a vehicle, comprising an elongated profile which upon collision is adapted for absorbing collision energy and forces, the bumper being prepared from a complete and hollow blank and being further provided with different cross sections along its more or less arched extension, and for the purpose of providing a structural beam or bumper bar which renders possibilities for rational and structural sturdy attachment to the frame of the vehicle, it is suggested that the bumper (1), has a substantially unchanged basic cross section (2) at each side of the centre (V-V), an outwardly pressed cross section (3) at the centre (V-V) in relation to said basic cross section (2), as well as a compressed or folded cross section (4) at the areas of each terminal portion.
(FR) Cette invention se rapporte à un longeron structurel ou un pare-choc, en particulier pour véhicules, qui comprend un profilé allongé qui, lors d'une collision, absorbe l'énergie et les forces de collision. Ce pare-choc est préparé à partir d'une ébauche complète et creuse et il comporte en outre différentes sections transversales sur sa longueur plus ou moins courbe et, afin de former une barre de longeron structurel ou de pare-chocs qui permette sa fixation robuste rationnelle et structurelle au châssis du véhicule, cette invention propose que le pare-choc (1) possède une section transversale de base essentiellement inchangée (2) de part et d'autre du centre (V-V), une section transversale emboutie vers l'extérieur (3) au centre (V-V) par rapport à cette section transversale de base (2), ainsi qu'une section transversale comprimée ou pliée (4) dans les zones de chacune des parties terminales.
