The present invention provides a gas generator for an air bag in which the weight of a coolant/filter is reduced. The air bag gas generator comprises a housing having a gas discharge port, an ignition means chamber in which ignition means are accommodated, and a combustion chamber in which a gas generating agent is accommodated, a cylindrical coolant/filter disposed between the combustion chamber and the gas discharge port, so that combustion gas passes through the coolant/filter prior to discharge through the gas discharge port, and the air bag gas generator meeting the following requirements (a), (b), and (c):
(a) that the gas generating agent have an amount of heat generation of 10 to 30kcal/mol;
(b) that the mass (g) of the coolant/filter in relation to 1 mol of gas generated during combustion of the gas generating agent be 20 to 65g/mol; and
(c) that the coolant/filter have a thickness of not less than 4.0mm. |
