Abstract: When a gas generating agent 9a inside a first combustion chamber 5a is burnt, a gas generating agent 9b is prevented from being burnt by function of a metal thin plate 11 closing a communication hole 10 with a second combustion chamber 5b. A cup 1190 having a hole 1191 is covered on an igniter 1112, and the flame thereof advances into a transfer charge 1116 straightly in a narrow width. Accordingly, since the transfer charge 1116 is burnt completely, sufficient flame for burning a gas generating agent 1109 can be generated securely. A communication hole 3010 between a first combustion chamber 3005a and a second combustion chamber 3005b is closed by double-layered seal tape 3011 laminated through an adhesive layer. After activation, the seal tapes 3011 are not ruptured due to increase in the internal pressure of the first combustion chamber 3005a, but they are peeled off easily due to increase in the internal pressure of the second combustion chamber 3005b.

Abstract: A gas generator for an air bag has gas discharge ports closed by a seal tape and has two different opening areas. When a pressure inside the gas generator increases due to combustion of a gas generating agent, a gas discharge port having a larger area is first opened to decrease the internal pressure. Subsequently, as the pressure further increases a gas discharging port having a smaller area is opened to decrease the internal pressure.
