Abstract
A piston-cylinder unit, which erects a swingable roll bar in a crash situation by an ejection spring, includes a controllable drive by which the movement and the direction of movement of the piston can be controlled and which can be disengaged in the event of a crash pulse, whereupon the piston extends rapidly by virtue of the ejection spring.
