Abstract
The present invention is an inflator with an improved reliability wherein a charge holderfor giving directivity to an detonation wave generated due to combustion of a primingis provided to an igniter, thereby promoting rupture of a rupturable plate. A cross-shaped notch is applied to a surface of the rupturable plate, and when the rupturable platereceives a rupture pressure from the igniter, four portions of the rupturable plate lap so that the outflow of the pressurized medium can be secured and fragments cannot be made. An inflator housingand a diffuserare connected by screwing a male screw portion on an outer surface of the end portion in the inflator housinginto a female screw portion on an inner surface of the end portion in the diffuser portion. An existing gas cylinder can be used in this method. A diffuser portionis connected in the opening portion side of a housing, and a gas discharging portis connected to the diffuser portion. The outflow direction of the pressurized medium and the axial directions of the inflator housingand the gas discharging portare coincident with each other at actuation. The diffuser portionis connected in the opening portion side of the inflator housing, and the gas discharging portis connected to the diffuser portion, and two filter meansandare arranged. After actuation, foreign objects included in the pressurized medium can be removed by the filter meansand
