ABSTRACT:
An impact absorber for decelerating a vehicle impacting on an obstacle, which impact absorber includes two tubes which can be displaced one inside the other in the manner of a telescope. The inner tube is closed off from the outside by a base and has a highly pressurized gas space and a first fluid space. A second fluid space is arranged in the outer tube and is hydraulically connected to the first fluid space via a restriction formed by a restricting aperture in an intermediate wall fixed in the inner tube. The outer tube has, in the end region, a plastic disk which melts at a predetermined temperature and as a result counteracts an explosion of the impact absorber in the event of a fire by reducing the pressure.
