Abstract: In a safety steering wheel, the ring and spokes are jacketed in a polyurethane integral foam of which the cap covering the integrated air bag unit is also made. To improve appearances the jacketing and the cap merge materially with one another.

Abstract: A device is provided for making a firm but releasable joint between a steering wheel which is connected to the steering column and a locking bolt that is movable by means of a lock cylinder.In order to provide between the hub of the steering hub and the locking bolt a joint which cannot be forcibly released from the outside, the diecast steering wheel hub is pot-shaped on the side facing the steering column and its cylindrical flange which in concentric to the steering column is provided on its inside periphery with a multiplicity of axial grooves for receiving the locking bolt. A metal ring is provided in front of the end faces of the grooves and is firmly connected to the land disposed between the grooves.

Abstract: In a steering wheel covered with a layer of plastic material, the steering wheel hub is connected to the steering wheel rim by a steering wheel spoke. To reduce the manufacture expenditure, the spoke is embedded in the steering wheel hub consisting of an aluminum pressure diecasting and the spoke as well as the portion of the steering wheel rim to which the spoke is connected are embedded by a pressure-diecast layer.

Abstract: Disclosed is an improved three-point safety belt for use in an automobile having a body containing a door where the three-point safety belt is secured at one end to the body and at the other end to a region of the body proximate the door. The three-point safety belt comprises an automatic winder and a pelvis strap mount, the pelvis strap mount being connected to a first prestressed spring, the mount being slidably mounted on a rod having on at least one side thereof engaging means. The mount has connected thereto cooperating engaging means for engaging the engaging means on the rod. The mount cooperating engaging means engages the engaging means on the rod when the mount is urged toward the spring. The mount is mounted against a release mechanism responsive to a threshhold deceleration, whereby when the threshhold deceleration is exceeded, the release mechanism releases the mount and allows the same to slide on the rod.
