ABSTRACT:
An assembly is provided for mounting 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 (39) covering the steering wheel armature (10), the vehicle occupant restraint (50), and the inflator (15). A rotatable fastener (30), when rotated, axially forces the assembly onto the steering shaft with the hub (34) non-rotatably attached to the steering shaft. The fastener (30) has a first portion (33) for threaded engagement with the threaded end portion of the steering shaft and is movable axially toward the steering shaft due to the threaded engagement when rotated in one direction. The hub (34) has a surface (34a) for supporting said fastener (30) for rotation relative to the assembly. The fastener (30) includes a second driven gear portion (32) fixed to the first portion (33).
