Luftsackeinrichtung für die Verwendung bei einem Fahrzeuginsassensitz, insbesondere bei einem Fahrgastsitz

摘要

An air bag device for use in a passenger's seat is formed of a retaining box having an opening disposed at the front face for expanding an air bag and air intake ports disposed on the lateral side for intaking air, seat-like valves disposed in the retaining box, the valves being capable of covering the lateral sides thereby closing the air intake ports and moving from the lateral side thereby opening the air intake ports, a gas generator disposed to the deep inside of the retaining box, and a lid for covering the opening of said retaining box. The valves are made of such a material as melting at a temperature lower than the igniting temperature of the gas generator.
