Abstract: An impact absorber for decelerating a vehicle during a collision with an obstacle by hydraulic damping forces and pneumatic spring forces includes two tubes that are telescopically displaceable one inside the other. An internal tube of the two tubes is closed off to the outside by a base. A gas space subjected to high pressure is disposed adjacent said base and interacts with a first liquid space via a separating piston which is axially guided in the internal tube in a sealed manner. The first liquid space is hydraulically connected to a second liquid space via a throttle opening through an intermediate wall attached inside the internal tube. A working piston attached to a piston rod is guided in the internal tube in a sealing manner and interacts via the piston rod with a third liquid space in an external one of the two tubes. A control which can be connected to two chambers is provided to extend the impact absorber or to return it to a normal position.

A second fluid chamber is formed by the outer tube and connected to the first fluid chamber via the partition. The outer tube has a tapering region directed away from the partition, and a deformation element dividing the second fluid chamber into two part chambers.
