Gas generating system

Abstract

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