A gas generator ( 10 ) includes an igniter ( 27 ) and first and second inflation gas generant compositions ( 52, 52 ') positioned to enable fluid communication with the igniter ( 27 ) upon activation of the igniter. Flow regulators ( 54, 54 ') are provided to regulate a flow of combustion products from the igniter ( 27 ) to the first and second inflation gas generant compositions ( 52, 52 '), to correspondingly regulate a time period between activation of the igniter ( 27 ) and initiation of combustion of the first and second inflation gas generant compositions ( 52, 52 '). In another aspect, the gas generator ( 10 ) includes a modular baffle system ( 70 ) including a first baffle chamber ( 71 ) in fluid communication with an inflation gas generant combustion chamber ( 50 ) for receiving therein combustion products from combustion of an inflation gas generant ( 52 ) positioned in the combustion chamber. An outer baffle chamber ( 74 ) is also positioned radially outwardly from the first baffle chamber ( 71 ) for receiving therein combustion products from the first baffle chamber. In yet another aspect, the gas generator includes a first enclosure ( 12 ), a second enclosure ( 24 ), and a projection ( 44 ) formed on one of the first enclosure and the second enclosure. An aperture ( 46 ) is formed in the other one of the first enclosure ( 12 ) and the second enclosure ( 24 ) for receiving the projection ( 44 ) therein. At least a portion of the projection ( 44 ) is fixed within the aperture ( 46 ) to prevent withdrawal of the projection ( 44 ) from the aperture ( 46 ), thereby securing together the first enclosure ( 12 ) and the second enclosure ( 24 ).
