Abstract:
A gas generator for an air bag, comprising:a housing having at least one gas discharge port;igniting means that is actuated when an impact sensor detects an impact;solid bodies of gas generating agent that are ignited by the igniting means and burned to generate a combustion gas; andcoolant/filter means for cooling the combustion gas and scavenging combustion residues, said igniting means, said gas generating agent and said filter means being accommodated in said housing, whereina ratio (A/At) of a total surface area A of said solid bodies of gas generating agent to a total opening area At of said at least one gas discharge port is limited to be larger than 300, andwherein 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, are each 25% or less of the maximum output pressure in the tank pressure test at 20.degree. C.
