ABSTRACT:
An apparatus includes an assembly to be mounted on a vehicle steering shaft which rotates about an axis to steer the vehicle and which has a threaded end portion. The assembly includes a steering wheel armature (10), a hub (34) fixedly connected to the steering wheel armature (10) and for non-rotatable attachment to the steering shaft, an inflatable vehicle occupant restraint (50), an inflator (15) for providing inflation fluid for inflating the vehicle occupant restraint (50), a frame (24) supporting the vehicle occupant restraint (50), and the inflator (15) on the steering wheel armature (10), and a cover (35) covering the steering wheel armature (10), the vehicle occupant restraint (50), and the inflator (15). A rotatable fastener (30) axially forces the assembly onto the steering shaft with the hub (34) non-rotatably attached to the steering shaft. The fastener (30) has an attachment portion (33) for threaded engagement with the threaded end portion of the steering shaft. The assembly has a surface (34a) for supporting the fastener (30) the assembly for rotation relative to the assembly. The fastener (30) includes a driven gear portion (32) fixed to the attachment portion (33) and for rotating the fastener in one direction relative to the assembly about the axis of the steering shaft to effect the axial forcing. A driving gear (40) forms a part of the assembly and is in meshing engagement with the gear portion (32) of the fastener (30).
