Abstract:
1. A device for absorption of impact energy on an automobile vehicle, with at least one energy absorber arranged between a bumper and the vehicle chassis and having a deformation element which deforms in the event of a collision, whereby the energy generated during the collision on the vehicle is at least partially converted by its deformation into deformation work, wherein the absorption characteristic of the at least one energy absorber ( 1 ) depends on the driving situation, by supplying the impact energy to the deformation element inside the at least one energy absorber ( 1 ) through at least one force introduction element ( 3 ), which either forms in cooperation with other elements ( 5 , 10 , 10 ′) a rigid arrangement which transfers the impact energy directly to the deformation element ( 2 ) for conversion into deformation work, or transfers the impact energy only after an excursion-limited motion inside the at least one energy absorber ( 1 ) to the deformation element ( 2 ) for conversion into deformation work, whereby the force introduction element ( 3 ) is blocked or released for movement by an actuator ( 7 , 8 , 9 ), with the actuator being operated based on a driving situation that is determined by the motion characteristic of the vehicle and/or by a driving situation detected by sensors.
