Driver Side Air Bag Module

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

DESCRIPTION
The driver side air bag module is mounted in the center of the steering wheel and consists of the following components:

Inflator
- When the sensors close, signaling a crash, electrical current flows to the air bag inflator.
- Inside the inflator, an igniter converts the current into thermal energy, causing ignition of the inflator gas generant.
- This ignition reaction combusts the sodium azide/cupric oxide gas generant in the inflator, producing nitrogen gas, which inflates the air bag.

NOTE: The inflator assembly is not a serviceable item.

Air Bag
The air bag is constructed of uncoated nylon. It is 672 mm (26.5 inches) in diameter and fills completely in approximately 40 milliseconds.

NOTE: The air bag is not a serviceable item.

Mounting Plate and Retainer Ring
The mounting plate and retainer ring attach and seal the air bag to the inflator.
- The mounting bracket and housing are also used to attach the trim cover and to mount the entire driver side air bag module to the steering wheel.

NOTE: The mounting plate and retainer ring are not serviceable items.

Steering Wheel Trim Cover
The cover is an injection-moulded plastic component which encases the driver side air bag module.
- When the air bag is activated, tear seams moulded into the steering wheel trim cover separate to allow inflation.

NOTE: The steering wheel trim cover is not a serviceable item.
