Abstract:
A method of manufacturing a gas generator for an air bag, comprising:providing a housing with at least one gas discharge port;providing, within the housing, an igniter that is actuated when an impact sensor detects an impact;providing, within the housing, solid bodies of gas generating agent that are ignited by the igniting means and burned to generate a combustion gas;providing, within the housing, coolant/filter means for cooling the combustion gas and scavenging combustion residues;limiting a ratio (A/At) of a total surface area A of the solid bodies of gas generating agent to a total opening area At of the at least one gas discharge port to be larger than 300; andlimiting each of a difference between the maximum pressures at 85.degree. C. and 20.degree. C. and a difference between the maximum pressures at 20.degree. C. and -40.degree. C. obtained in tank pressure tests using a tank, whose capacity is 60 l, to 25% or less of the maximum output pressure in the tank pressure test at 20.degree. C.
