Air Bag Modules
WARNING: This page is about a different car, the 2002 Pontiac Montana, 2002 Oldsmobile Silhouette, and 2002 Chevrolet Venture. However, it is still accessible from the selected car via links, so may be relevant.
Air bag modules consist of an inflatable bag and inflator. When vehicle is in an accident of sufficient force, SDM causes current flow through deployment loops. Current passing through deployment loops ignite inflator charges, producing gas which rapidly inflates air bags.
