Erecting mechanism for a swivel-up rollover bar for vehicles, in particular for four-seat convertibles, having a bar leg which is supported in a swivel bearing on one vehicle side and which can be swivelled about a transverse axis of the vehicle and has a supporting section which is remote from the swivelling axis and serves to support the vehicle during a rollover movement the supporting section of the bar leg is swivelled up on a curved path which extends, at least over a partial swivelling angle, around the swivel bearing on a path different from a circular arc by virtue of the fact that the useful length of the bar leg varies with the stroke.

A self-supporting motor-vehicle body includes outer lateral side members (sills) on a substructure in the region of the passenger cell, and front and rear side members which are angularly offset relative to a longitudinal center axis of the vehicle and respectively located at a vehicle forward structure and at a vehicle rearward structure. The front and rear side members adjoin the lateral side members via a bent portion. In order to provide stiffening of the body, struts are secured to the substructure of the body so as each to be fastened at one end to a lateral side member, and directed towards a middle region of the vehicle with their other end fastened once again to the substructure of the body. A front strut is guided from each of the two lateral side members into the vehicle forward structure and/or a rear strut is guided from each of the two lateral side members into the vehicle rearward structure, with each strut preferably being aligned at an angle of approximately 45.degree. relative to the longitudinal axis of the vehicle, and extending along the substructure at least into the middle region of the vehicle.

An axially adjustable steering device for motor vehicles comprises two jacket-tube parts, of which the inner jacket-tube part is displaceable telescopically in the outer jacket-tube part by means of a controllable drive, a worm gear received in a reception part pivotably mounted fixedly relative to the vehicle acting on an axial tooth-profile part on the inner jacket-tube part in a longitudinally displacing manner. The reception part is retained via a locking mechanism in an engagement position of the worm gear and tooth-profile part, and this locking mechanism is releasable in a controlled manner during a front collision, after which the worm gear is pivoted out of engagement with the tooth-profile part and the inner jacket-tube part is moveable into a position shifted furthest in the forward direction.

To prevent the possibility of the upper extremities of a strapped-in passenger in a convertible vehicle from going beyond the extension of the tiltable roll bar in the event that the vehicle turns over, despite the fact that the roll bar is erected, the latter is extended beyond its particular pivoting point, and this extension engages around the shoulder-belt part between its deflection point and the lower fastening point, and when the roll bar is swung up, causes a tautening of the belt-band run because the shoulder-belt part is taken up.
