  • Two chamber inflator body
    Patent number: 5934705
    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. An insulating disc disposed between the two chambers precludes flame front and thermal propagation from one chamber to another, thus preventing redeployment of an activated airbag.
