ABSTRACT:
An air bag system to protect occupants of automobiles against injury in case of collision. An air bag is housed, when empty, in a tapered open container in the passenger compartment of the car. It is inflated by compressed air from an air tank in the vehicle. Inflation is controlled by solenoid valves actuated by switches responsive to excessive brake pedal pressure, harness tension, or force against the front bumper. The speed of inflation may vary. A manual switch controls a deflation pump which deflates the bag and also mechanically draws it back into its container. Normal repeated use of the brake pedal operates air pumping means to keep up the pressure in the air tank.
