1. A gas generating system comprising:
- a first chamber activatable to provide a first quantity of gas;
a shell positioned within the first chamber and defining a second chamber activatable independently of the first chamber to provide a second quantity of gas;
a single opening enabling fluid communication between the second chamber and the first chamber; and
a barrier sealing the opening to prevent fluid communication between the first and second chambers prior to activation of the second chamber, the barrier being configured to enable pressurized gases to flow from the second chamber through opening and between the barrier and the shell prior to a failure of the barrier.

8. A gas generating system comprising:
-
a housing; a first chamber within the housing and structured to be activatable to provide a first quantity of gas; a shell including a flat base and a wall extending from a periphery of the base so as to define a second chamber positioned within the first chamber and structured to be activatable independently of the first chamber to provide a second quantity of gas; a single opening formed along the base and enabling fluid communication between the second chamber and the first chamber; and a barrier sealing the opening to prevent fluid communication between the first and second chambers prior to activation of the second chamber. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
