ABSTRACT:
The present invention provides an inflatable air bag with a plurality of air valves and at least one internal, gas-operated extension member for deploying the bag, with three such members being preferred. The extension members are generally tubular, being inside the bag. Each is attached at its first, base end to a gas source, its second end being free. Prior to deployment of the air bag, the extension members are compactly within the bag. On demand, a gas source is activated to inflate the extension members, straightening each quickly into a substantially straight, elongated pressurized tube expanding the bag. Ambient air from the passenger compartment of the vehicle flows rapidly into the bag as it expands to create an impact-absorbing cushion.
