INFLATOR OF AIR BAG DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an inflator of air bag device capable of enhancing the producibility. SOLUTION: An inflator 10 is structured so that a gas producing agent 19 is combusted through ignition actuated by heat emission of heating elements 24 installed in an ignition 21 so that an inflating gas is produced for inflating an air bag. An explosive 26 of Class 8 according to the hammer drop sensitivity test (JIS K4810-79) and Class 7 according to the friction sensitivity test (JIS K4810-79) is put around the heating elements 24 in the area between them and gas producing agent 19 in such a way as in tight attachment to the heating elements 24.
