ABSTRACT:
The energy absorbing device for use as a composite bumper on a vehicle comprises a deformable unit providing a constant energy absorption, the unit being disposed in contact with a resisting structure and a flexible shield, and consisting of a number of energy absorbing members, each energy absorbing member being formed by the juxtaposition of a plurality of elongated hollow members having different lengths. Provision is made within the energy absorbing device of sections having an increasing impact resistance as the impact stress causes the energy absorbing device to be crushed, the stiffness of the energy absorbing device being thus enhanced as a function of the driving in thereof.
