Abstract

An extendable element absorbs impact energy from a baffle and is capable of being moved by a trigger connected to a collision monitoring system. The device is moved in the longitudinal direction out of an initial position, in which it is received essentially in a vehicle side member, into a working position and is capable of being detained in this position. At the same time, the extendable element is guided in a cylinder arranged in the vehicle side member. The cylinder is connected to the vehicle side member via a turn-up profile arrangement which is capable of being transferred out of a position of rest into a deformation position.
