Abstract

A gas generator utilizes two segregated propellant container/combustion chambers, each having a plurality of nonazide propellant grains therein, and each having an igniter for separately igniting the propellant grains located within the respective chambers. A perforated insulating tube 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.
