発明の名称
(EN) IMPACT ABSORBING BODY FOR VEHICLE
(FR) CORPS ABSORBEUR DE CHOCS POUR VEHICULE
(JA) 車両用衝撃吸収体
要約
(EN)
A hollow impact absorbing body (1) for a vehicle manufactured by blow-molding thermoplastic resin and internally mounted on vehicle component members for preventing the impact absorptivity of the recessed ribs to be lowered by buckling and preventing resin accumulation from occurring in a blow molding process, comprising walls (3) and (4) opposed to each other, wherein the tip parts of the plurality of recessed ribs (5) and (6) formed by recessing the walls toward the other opposed walls are welded to each other, the height of the recessed ribs from the walls to welded surfaces (7) is set to 15 to 45 mm and the thickness of all the ribs is 30 to 90 mm, and connection ribs for connecting the adjacent recessed ribs to each other are provided to support the recessed ribs, whereby the accumulation of the resin can be prevented by providing swelled parts at parts of the weld surfaces.
(FR)
L'invention concerne un corps creux absorbeur de chocs (1) destiné à un véhicule. Ledit corps est fabriqué par moulage par soufflage de résine thermoplastique et monté de manière interne sur des éléments constitutifs de véhicules afin d'empêcher que la capacité d'absorption des chocs des nervures creuses ne diminue par flambement et afin d'empêcher qu'une accumulation de résine ne survienne dans un procédé de moulage par soufflage. Ledit corps comprend des parois (3) et (4) opposées les unes aux autres, les parties d'extrémité de la pluralité de nervures creuses (5) et (6) formées par creusement des parois vers les autres parois opposées sont soudées les unes aux autres, la hauteur des nervures creuses depuis les parois jusqu'aux surfaces soudées (7) est comprise entre 15 et 45 mm et l'épaisseur de l'ensemble des nervures est comprise entre 30 et 90 mm, et des nervures de liaison permettant de relier les nervures creuses adjacentes les unes aux autres sont présentes afin de supporter les nervures creuses, l'accumulation de la résine pouvant ainsi être empêchée par utilisation de parties gonflées au niveau de parties des surfaces de soudure.
