摘要： A dual-type gas generator for inflating air bags is provided in which a first igniter structure having a first combustion chamber accommodating a first gas generating material and a second igniter structure having a second combustion chamber accommodating a second gas generating material both exhaust, when activated, to exhaust gas to a common filter chamber. When the igniter structures are intended to be activated separately and with a time lag, gas generated in the first chamber often flows into the second chamber and may ignite the second gas generating material. This malfunction can be prevented by various flame-transferring preventing structures that preclude direct flow of gas from the first chamber into the second chamber through the common filter chamber.

摘要： A gas generator for an airbag producing no malfunction is provided. When the first combustion gas generated in the first combustion chamber 30 enters the filter chamber 50, most of the gas is discharged through the gas discharge port 52, however, part of the combustion gas flows into the second through hole 62. This combustion gas flows through the vent hole 76 into the second combustion chamber 40 after changes its flow direction by the gas-flow inhibiting member 80 inside the second cap member 75. At this time, the temperature of the gas is lowered, so that the second gas generating agent 43 is never burnt.

摘要： A gas generator for an airbag allows maintaining combustibility as originally designed. An ignition energy generated by an activation of a first igniter 21 flows via a first communication hole 24, a first intermediate chamber 30 and second communication holes 43, into a second combustion chamber 40, to cause a gas generating agent 43 to ignite and burn. The ignition energy flows into the second combustion chamber 40 with making a detour, and therefore, the gas generating agent prevents from broken by the impact and the combustibility thereof is never changed.

摘要： A filter for a gas generator in which the manufacture is simple, which has an adequate filter performance and cooling performance and, furthermore, which has high reliability with little damage caused in actuation of the gas generator, is provided. The filter for an air bag gas generator comprises a first layer formed from helically wound wire rods having a cross-sectional area of 0.03 to 0.8 mm2, in such a way that the pitch angle of wire rods vertically superposed in the radial direction is symmetrical, and a second layer that exists on the outer side of the first layer in the radial direction and is formed to have a finer filter particle size than the first layer using a wire rod narrower than the wire rod that forms the first layer.
