Driver Air Bag Module

Driver Air Bag

CAUTION: The driver air bag module is serviced as a complete assembly.

The driver air bag is mounted in the center of the steering wheel. The module consists of the following components:
^ Inflator
^ Mounting plate and retainer ring
^ Bag assembly
^ Steering wheel trim cover

Inflator
The inflator assembly is not a serviceable item. When the sensors close, signaling a crash, electrical energy flows to the air bag inflator. Inside the inflator, an igniter converts the electrical signal to thermal (heat) energy, causing the ignition of the inflator gas generant. This ignition reaction combusts the sodium azide / copper oxide gas generant in the inflator, producing nitrogen gas, which inflates the air bag.

Air Bag
The air bag is constructed of neoprene coated nylon, is 711 mm (28 inch) in diameter and fills to a volume of about 0.065 m (2.3 cubic ft) in approximately 40 milliseconds. It is not a serviceable item.
