摘要： A gas generator for inflating an inflatable article such as a safety bag or raft, has a reaction chamber (1) surrounded by a ring-shaped filter chamber (2). First gas exit openings (10 to 15) permit generated gas to flow from the reaction chamber into the filter chamber. Second gas exit openings (22) lead from the filter chamber into the inflatable article. A temperature responsive flow control is provided to make sure that the inflation efficiency or the inflation pressure inside the inflated article is substantially constant and substantially independent of the temperature of the gas generator at which the ignition of a gas generating fuel begins. For this purpose the total cross-sectional flow area of the first gas exit openings and/or the average gas flow path length between the first and second gas exit openings is controlled so that with a rising temperature the flow cross-sectional area and/or average path length is increased while the area and/or path length is decreased in response to a decreasing temperature.

A structure is arranged in the combustion chamber for holding down the propellant granule, which has a disc-shaped holding face with grid holes, wherein the holding face is pressed into the combustion chamber and is connected in a form- and force-fitting manner with the combustion chamber wall. The structure for holding down the propellant granules is prestressed and presses elastically onto the propellant granules thereby arresting the propellant granules at a preselected filling level and at a variable distance from the combustion chamber cover.
