Abstract
A steering wheel assembly including an inflator subassembly, a steering wheel armature, and a cushion subassembly. The inflator subassembly and the cushion subassembly are located on opposite sides of the steering wheel armature. The inflator subassembly comprises an inflator. The inflator subassembly has a lip, which fits into a circular channel on the bottom portion of the steering wheel armature. The cushion subassembly includes an airbag, a retainer, and an airbag cover. Upon detection of a crash from a crash sensor, the inflator begins to generate gas. The gas flows through the inflator subassembly and then is forced to flow through the hub portion of the steering wheel and into the cushion.
