The rate of combustion of an electrically operated propellant having self-sustaining threshold of at least 1,000 psi is controlled to produce chamber pressures that are sufficient to produce a desired pressure profile in the airbag to accommodate a range of human factors and crash conditions yet never exceeding the self-sustaining threshold. The combustion of the propellant is extinguished to control the total pressure impulse delivered to the airbag. Propellants formed with an ionic perchlorate-based oxidizer have demonstrated thresholds in excess of 1,...
1. A method of deploying and inflating an airbag comprising: providing a combustion chamber;providing an amount of electrically operated propellant within the combustion chamber, said propellant comprising an ionic perchlorate-based oxidizer such that the propellant has a self-sustaining threshold pressure of at least 1,000 psi at which the propellant once ignited by an electrical input cannot be extinguished and below which the propellant can be extinguished by interruption of the electrical input;coupling the airbag to the combustion chamber;igniting t...
