Abstract: An impact absorber is provided for absorbing impact forces especially in case of a collision of a motor vehicle. The impact absorber includes an inner tube (1), which can be pushed into an outer tube (2) in a telescopic manner and which is closed with a bottom plate (3) at its free end projecting from the outer tube (2). Starting from the bottom plate (3) in the direction of the longitudinal axis (4) of the impact absorber, a gas space (5) filled with pressurized gas and a first, a fluid-filled liquid space (7), which is separated from the gas space (5) by a wall (6) displaceable in the inner tube (1), are arranged in the interior of the inner tube (1). The liquid space (7) is in connection through a throttle element with a second, fluid-filled liquid space (13), which adjoins the first liquid space (7) in the direction of the longitudinal axis (4) and is closed by a piston (9) fixed in the outer tube (2) towards the free end of the outer tube (2) in a liquid-tight manner.

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.
