Abstract

A shock absorber for a motor vehicle has a deformation body, which can be deformed in the case of a collision and into the path of which a blocking part protrudes, with which, due to the forces acting during a collision, a plastic deformation of the deformation body is achieved with absorption of the collision energy, it being possible to increase the deformation resistance of the deformation body by directing it into an additional deformation stage. For this purpose, the blocking body has at least two switched positions, in which it protrudes into the path of movement of the deformation body, as a result of which the deformation body is plastically deformed to a greater or lesser extent due to the forces acting during impact.
