<p>A gas generator (10) utilizes two segregated propellant container/combustion chambers (38, 40), each having a plurality of nonazide propellant grains (42, 44) therein, and each having an igniter (50, 52) for separately igniting the propellant grains located within the respective chambers. A perforated insulating tube (20) disposed between the two chambers precludes flame front and thermal propagation from one chamber to another, thus preventing redeployment of an activated airbag. Alternatively, a gas generator may contain two separate inflator subassemblies insulated to prevent heat conduction from one subassembly to another.</p> |
