Abstract
A gas generator (10) which generates propellant gas for inflating a gas bag in an air bag system comprises a housing (11) having a combustion chamber (21) which is formed by an upper part (12) of the housing and a lower part (13) of the housing in the interior of the housing (11), discharge openings (32) in the housing (11) for the exit of the propellant gas from the housing (11) into the gas bag, a filter device (30) upstream of the discharge openings (32) and an ignition device (23) for igniting a solid propellant (22) contained in the combustion chamber (21), the propellant gas escaping from the combustion chamber (21) being directed out of the housing (11) via flow chambers (29). The combustion chamber (21) is formed by an interior space of a tubular insert (18) which is fixedly held between the upper part (12) of the housing and the lower part (13) of the housing, and the tubular insert (18) comprises outlet openings (32) into an annular flow chamber (29) between the tubular insert (18) and the housing (11). The tubular insert (18) has tabs (27) bent radially outwards which, on the one hand, form the outlet openings (28) and, on the other hand, serve as a means for holding the filter device.
