LIQUID GAS GENERATOR FOR CRASH PROTECTING CUSHION EXPANDABLE TO PREVENT AUTOMOBILE PASSENGER FROM INJURY

摘要

PURPOSE: To control gas generation for an overall drive continuing time and to reproducibly conduct it by connecting an interior of a reaction container with a hollow chamber in a casing through a communicating passage of a puncture element through all of the container by a puncture member, and breaking a breaking diaphragm between a flow-out chamber and the hollow chamber by a pressure. CONSTITUTION: A reaction container 32 closed to receive a liquified gas 36 is provided in a casing 18, and a hollow chamber 54 and an ignition member 56 are provided adjacent to the container 32. A puncture member 58 is movably disposed in the chamber 54. When the member 56 is operated, combustion gas of liquified gas 36 from the container 32 is passed through a communicating passage 68 into the chamber 54. Further, to discharge combustion gas generated in the case of burning the gas 36 to exterior, a flow-out chamber 30 opened to the chamber 54 is provided, the chamber 30 is closed to the chamber 54, and a breaking diaphragm 7 to be destroyed when burning gas in the chamber 54 arrives at a lowest pressure is provided.
