A passive restraint system that automatically deploys during a crash to act as a cushion for the occupant. It creates a broad surface on which to spread the forces of the crash, in order to reduce head and chest injury. It is considered a "supplementary" system to the lap/shoulder belt because it enhances their protective action in frontal collisions.
safety devices installed in most newer vehicles that inflate to protect the driver and/or passenger in certain collisions.
An extrication tool, consisting of air sacs or bags, filler hoses, air regulator, control valves, and a supply of compressed air.
