ABSTRACT:
The present invention relates to an energy absorption device (1) for a bumper arrangement of a vehicle, with a hollow longitudinal section (2) intended for deformation, a rolled-back region (3) adjoining the hollow longitudinal section, and an extension section (4) connected to the rolled-back region. In order to improve an energy absorption device of this type to the extent that obliquely acting accident forces can be absorbed with a high degree of efficiency in as simple a manner as possible, it is proposed, in an initial state prior to energy absorption, to orient the hollow longitudinal section (2) obliquely with respect to the axial direction of the extension section (4).
