A pivotable rollover bar for motor vehicles, in particular for four-seater convertibles, which, bent in the shape of a U, surrounds the rear seating area of a passenger compartment in a lowered rest position. The rollover bar can be pivoted by a drive about lateral bearings on a vehicle body, about a transverse axis of the vehicle, into a raised operative position in which its crossbar spans the interior of the passenger compartment. The rollover bar is provided on its lateral limbs with a flattened portion on the side facing the interior of the passenger compartment, this flattened portion enlarging the interior or the passenger compartment at the sides of the seat. At least one supporting tube projects from the rollover bar towards the vehicle body, the supporting tube being displaceable together with the rollover bar and being guided in a guide in the vehicle body and positioned to take up forces in the transverse direction of the vehicle.

The proposed safety-belt arrangement in a vehicle has a three-point belt, for which an upper deflecting fitting, together with a guide part of a belt feeder arm, is retained on the vehicle center column so as to be vertically adjustable on a common support. The belt lug of the feeder arm can consequently be made as small as possible, while still accommodating passengers of varying sizes.

A wind-up mechanism for eliminating the belt looseness of a safety belt system when exceeding a predetermined deceleration, in which an ignitable propellant charge, provided for triggering the retraction movement of the belt is arranged centrally in the hollow shaft of a belt roller that blocks automatically in case of danger. A liquid medium is preferably disposed in front of the propellant charge which, after the ignition of the propellant charge, drives a rotor coupled at that instant with the wind-up roller so as to eliminate the belt looseness by the gases forming during the ignition of the propellant charge. The hollow shaft accommodates at one end a cap and a toothed rim connected therewith, into which engages a blocking mechanism triggered in case of danger, while at least a part of the rotor is formed-on at the other end of the shaft in the course of a cold-flow or casting operation.

A headrest for a motor vehicle in which an inflatable bellows forms the headrest which is provided with elastically yielding drawbands that return the bellows into its folded-together position when the bellows is deflated by withdrawing therefrom the pressure.
