    • A gas generator for an air bag which includes a short cylindrical container (21) for a gas generator having a central chamber (34), a ring-like outside chamber (35) communicating with the central chamber (34) and encompassing it and emission holes (36) for emitting a gas from the outside chamber (35) to inflate an air bag, a gas generating agent (51) accommodated in the ring-like outside chamber (35), ignition means (10, 40) accommodated in the central chamber (34) for burning the gas generating agent (51), and heat-insulating members (22, 23), (37, 38) for thermally insulating the gas generating agent (51) inside the outside chamber (35) from the container (21), disposed at least at the upper portion and/or at the lower portion of the inside of the outside chamber (35). Because the heat-insulating members (22, 23), (37, 38) are disposed at least the upper portion and/or the lower portion of the inside of the outside chamber (35) of the container (21), the influences of the ambient temperature on the gas generating agent accommodation space can be reduced and a combustion speed within a predetermined range can be obtained.
    • 一种用于气囊的气体发生器,其包括用于具有中心室(34)的气体发生器的短圆柱形容器(21),与中心室(34)连通并包围其的环状外室(35) 用于从外部室(35)排出气体以使气囊膨胀的孔(36),容纳在环状外部室(35)中的气体发生剂(51),容纳在该环状外部室中的点火装置(10,40) 用于燃烧气体发生剂(51)的中央室(34)和用于将外部室(35)内部的气体发生剂(51)热绝缘的隔热构件(22,33),(37,38) 容器(21),至少设置在外部室(35)的内部的上部和/或下部。 由于绝热构件(22,33)(37,38)至少设置在容器(21)的外部室(35)的内部的上部和/或下部,所以影响 可以降低气体发生剂容纳空间的环境温度,并且可以获得在预定范围内的燃烧速度。
