Abstract

L'invention concerne un système d'atténuateur de collision pour un déploiement devant une structure fixe comprenant un rail s'étendant le long d'une longueur du système d'atténuateur de collision et une pluralité de diaphragmes disposés initialement dans une relation espacée le long de la longueur du rail. Chaque diaphragme de la pluralité de diaphragmes se déplace le long du rail, de telle sorte que, lorsqu'une extrémité avant du système d'atténuateur de collision reçoit une force d'impact provenant d'un véhicule, un premier diaphragme des diaphragmes se déplace vers l'arrière le long du rail et frappe un deuxième diagramme des diaphragmes, de sorte que les premier et deuxième diaphragmes se déplacent davantage vers l'arrière le long du rail, ce processus continuant avec des diaphragmes supplémentaires jusqu'à ce que les forces d'impact soient totalement atténuées. Un élément de déchirement sur le système d'atténuateur de collision vient en prise avec un matériau formant un élément déchirable du système d'atténuateur de collision, le matériau de déchirement d'élément de déchirement formant l'élément déchirable pour augmenter l'atténuation de la force d'impact.
