  • Method for producing filter used in gas generating apparatus of car airbag
    Publication number: 20070138708
    Abstract: The present invention relates to a filter used in a gas generating apparatus of a car airbag. The car airbag is equipped with a gas generating apparatus for generating high temperature and high pressure, in which gunpowder is exploded by ignition of an igniter, by which a gas generating agent is burned. By combustion of a gas generating agent, a high temperature and high pressure gas is generated, which should be cooled down to be suitable for expansion of an airbag while impurities contained in the gas are removed. The present invention relates to a filter prepared by sintering a perforate plate with metal powder prepared by processing machining chips to meet the foregoing requirements.
