Abstract

L'invention concerne un dispositif de sécurité absorbant l'énergie, destiné à être monté sur un véhicule, qui comprend un absorbeur d'énergie et un moyen de guidage et de support. Ledit absorbeur d'énergie est constitué d'une plaque avancée et d'au moins un tube d'absorption d'énergie qui présente une partie de guidage enfoncée et une partie d'absorption d'énergie. Dans ladite plaque se trouvent des ouvertures de sortie correspondant au tube, dont la largeur est légèrement supérieure à deux fois l'épaisseur de la paroi du tube et la longueur est légèrement supérieure au diamètre extérieur du tube. La partie de guidage enfoncée passe par les ouvertures et est fixée audit moyen de guidage et de support. Le tube présente une longueur de déformation suffisante pour absorber l'énergie d'un impact. Lorsqu'un impact se produit, l'énergie de celui-ci est transmise aux éléments mobiles, puis l'énergie peut être graduellement absorbée par la déformation de la partie absorbant l'énergie.
