Energy Absorption Device, Especially For Non-Axial Loads
First Claim
1. An energy absorption device adapted to be disposed between a support structure of a vehicle and a bumper to absorb energy by deformation, the energy absorption device comprising:
- a deformable, hollow main profile extending in a longitudinal direction between a bumper side that supports the bumper and a support structure side that is mounted to the support structure, the support structure side being opposite the bumper side; and
a deformable auxiliary profile extending in said longitudinal direction between the bumper side and the support structure side, said deformable auxiliary profile fastened on said main profile in an area at the support structure side and in an area at the bumper side.

Abstract
The invention relates to an energy absorption device which can be arranged to absorb energy by deformation between a support structure of a vehicle and a damper, the energy absorption device carrying a deformable main profile which has a hollow body-type cross-section. The aim of the invention is to improve an energy absorption device of the aforementioned type in such a manner that the energy can be well carried off even if the forces produced by an accident impact the energy absorption device at an angle. For this purpose, a deformable supplementary profile is provided on the cross-section of the main profile.
