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： An airbag gas generator with a simple construction, which operates to apply as small an impact as possible to the passenger during the initial stage of its operation and thereafter rapidly increase the gas pressure to reliably protect the passenger. The airbag gas generator which includes in the housing with gas discharge ports a single ignition means activated by impacts, a gas generating agent ignited and burned by the ignition means to produce a combustion gas, and a filter means to cool the combustion gas and/or arrest combustion residue. The operation performance of the gas generator is adjusted such that the tank pressure measured at 0.25×T milliseconds will be 0.25×P (kPa) or less where a desired tank maximum pressure in the tank combustion test is P (kPa) and a period of time from the start of rising of the tank pressure to the time when the maximum pressure P (kPa) is reached is T milliseconds.
