Description

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 (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 a portion (33) for threaded engagement with the threaded end portion of the steering shaft. The assembly has a surface (34a) supporting the fastener (30) on the assembly for rotation relative to the assembly. The fastener (30) includes a driven portion (32) for rotating the fastener in one direction relative to the assembly about the axis of the steering shaft to effect the axial forcing.
