Abstract

L'invention porte sur un appareil (100) d'absorption de chocs dus aux collisions de véhicules dont, suite à un choc causé par un véhicule, les parois frontales (50) se déplacent facilement vers l'avant si bien que les guides (110) ne sont pas endommagés. Par ailleurs, les fixations (130) ne sont pas encastrés dans le sol mais fermement maintenus dans les fentes (61a) d'une échelle (61), tandis que les pneumatiques usagés (40) comprimés par le choc ne reviennent pas à l'état initial même si l'ajusteur de jeu est endommagé, ce qui évite une collision secondaire occasionnée par le mouvement dans la direction opposée de l'échelle (61).
