Air Bag Modules
WARNING: This page is about a different car, the 1995 Mitsubishi Mirage and 1995 Eagle Summit. However, it is still accessible from the selected car via links, so may be relevant.
Driver-side air bag module is mounted on steering wheel. See Figure and Fig 1 . Passenger air bag module is mounted in right side of dash. Air bag module inflator assembly produces nitrogen gas to fill air bag. When a small amount of current from SDU is applied, ignitor starts a thermal reaction, which spreads an ignitor charge.
Surrounding ignitor charge is a pellet-filled area that produces nitrogen gas. Gas pressure builds and discharges from inflator through a diffuser and screen assembly, forcing trim cover to burst along its seams until air bag is fully inflated. When air bag is fully inflated, gas escapes through vents on sides of air bag.
