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.

Drive arrangement for a roll bar of motor vehicles

To economize weight, an arcuate support tube of a roll-over yoke is produced from high-tensile heat-treated material and received by both members and by part of the adjacent median region in bracing structures which mount it on the motor car body and which consist respectively of two mutually connected half-shells which positively enclose and thereby retain the support tube.

Roll over bar for motor vehicles

A device for actuating a safety device, in particular a roll bar in a motor vehicle. The device includes a first sensor which is actuated when a vehicle acceleration exceeding a predetermined limiting value occurs and which generates a switch signal for a release device to activate the roll bar. The device also includes second and third sensors which control switches when both at least one wheel suspension is fully extended and the vehicle is tilted about either a longitudinal or transverse axis, so as to actuate the safety device during even relatively slow overturns.
