ABSTRACT:
A device for absorption of impact energy on an automobile is provided, with at least one energy absorber arranged between a bumper and the vehicle chassis, which has a deformation element which deforms in the event of a collision. The device adapts to different driving and risk situations and which has a simple design and can be manufactured cost-effectively. The absorption characteristic of the energy absorber is implemented to adapt to the driving situation. This is achieved by transferring the impact energy to the deformation element inside the energy absorber via at least one force introduction element which, depending on the respective driving situation, either transfers the impact energy directly to the deformation element for conversion into deformation work, or initially performs an excursion-limited motion inside the energy absorber and only thereafter transfers the impact energy to the deformation element for conversion into deformation work.
