Abstract

Dispositif de sécurité absorbeur d’énergie apte à se monter en une partie extrême de véhicule, en particulier en partie avant d’un véhicule automobile, caractérisé en ce qu’il comprend au moins un boitier absorbeur d’énergie déployable (1, 1’), qui est non déployé en position inactive, et configuré apte à passer vers une position active de sécurité en se déployant puis apte à se rétracter jusqu’à se compacter par déformation sous la contrainte d’un choc. Figure à publier avec l’abrégé : Fig. 2Energy-absorbing safety device suitable for mounting in an end part of a vehicle, in particular in the front part of a motor vehicle, characterized in that it comprises at least one deployable energy-absorbing box (1, 1' ), which is undeployed in the inactive position, and configured capable of passing to an active safety position by deploying then capable of retracting until it is compacted by deformation under the stress of an impact. Figure to be published with abstract: Fig. 2
