Abstract: A passenger motor vehicle includes a body, a side door movable between a closed position and an open position, a side door fixing element, and a body stop element. The side door fixing element is disposed on the side door and the body stop element is disposed above the side door fixing element in a vertical direction of the passenger motor vehicle when the side door is in the closed position. The side door fixing element and the body stop element have an offset relative to each other in a transverse direction of the passenger motor vehicle when the side door is in the closed position. The side door is reshapeable as a result of an impact on the side door such that the side door fixing element is displaceable against the body stop element.

Abstract: A window guide for a side window of a motor vehicle side door in the vicinity of a door frame includes a frame profile, an inner cladding, and an outer cladding. The frame profile is made Z-shaped throughout, with an inner Z-leg flanking the window glazing being secured to a parallel connecting flange of the inner cladding and an outer Z-leg pointing away from the window glazing being attached flush to a parallel inner surface of the outer cladding.

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.

Abstract: 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.
