摘要： 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.
摘要翻译：当第一燃烧室5a内的气体发生剂9a燃烧时，通过利用第二燃烧室5b关闭连通孔10的金属薄板11的功能，防止气体发生剂9b被燃烧。具有孔1191的杯1190被覆盖在点火器1112上，并且其火焰以窄的宽度直线前进到传送装料1116。因此，由于转印装料1116完全燃烧，因此可以可靠地产生用于燃烧气体发生剂1109的足够的火焰。第一燃烧室3005a和第二燃烧室3005b之间的连通孔3010由通过粘合剂层层叠的双层密封带3011封闭。激活后，由于第一燃烧室3005a的内部压力增加，密封带3011不会破裂，但是由于第二燃烧室3005b的内部压力的增加，它们容易剥离。

摘要： Combustion residues of a gas generating agent remain in an inflator due to composition of the gas generating agent, temperature difference between combustion gas and pressurized gas isolated by a rupturable plate, collision of the combustion gas against a wall surface and the like. The inflator inflates an air bag with pressurized gas and combustion gas, while satisfying the following requirements: (1) pressurized gas contains an inert gas and substantially no oxygen; (2) in the gas generating agent, a pressure is 0.8 or less; (3) a mole ratio of an amount of pressurized gas and the combustion gas is 1 to 10; (4) a ratio of a mass of pressurized gas and the gas generating agent is 1 to 10; (5) a mass of a gas generating agent is 1 to 30 g; and (6) the pressurized gas is charged at 30,000 to 67,000 kPa.

摘要： A gas generator is provided which is less likely to suffer from damages or peeling-off of a protruding seal tape during assembling of the generator, thus surely assuring a moisture preventive effect by the seal tape.In the gas generator for an air bag, a recess is formed in a portion of a partition wall that divides a housing into an ignition means storage chamber that stores igniting means and a gas generating agent storage means that stores a gas generating agent, or in a portion of a housing, to which a seal tape is attached to close through-holes formed through the partition walls or housing. The depth and width of the recess are equal to or larger than the thickness and width of the seal tape. The seal tape is attached such that its side edge portions are received in the recess, so as to close the through-holes.
