Abstract
A gas generating apparatus is provided which includes a first combustion chamber having a first opening and a second combustion chamber having a second opening. Each of the combustion chambers contains an ignitor and a propellant. A filter chamber that accommodates a filter is provided. The filter chamber is separated from each of the combustion chambers. The apparatus is configured so that a combustion gas produced in the first combustion chamber exits through the first opening and enters a first portion of the filter chamber without passing through the second chamber. The second combustion chamber extends through the filter chamber and the first combustion chamber.
