1. A multi-chamber gas generating system comprising:

  • an elongated housing including a housing wall;

    a divider secured within an interior of the housing to separate the interior of the housing into a first chamber and a second chamber, the divider forming a gas-tight barrier between the chambers,at least one opening formed in the housing wall to enable fluid communication between the first chamber and an exterior of the housing;

    at least one opening formed in the housing wall to enable fluid communication between the second chamber and the exterior of the housing;

    a first tubular member positioned within the first housing chamber, the first tubular member having at least one opening formed therein to enable fluid communication between an interior of the first tubular member and the at least one opening formed in the housing wall enabling fluid communication between the first chamber and the housing exterior;

    a second tubular member positioned within the first tubular member, the second tubular member including at least one opening formed therein to enable fluid communication between an interior of the second tubular member and the at least one opening formed in the first tubular member,the at least one housing wall opening enabling fluid communication between the first chamber and the housing exterior being axially displaced from the at least one opening in the first tubular member such that combustion products flow in one of a first axial direction and a second axial direction between the at least one opening in the first tubular member and the at least one housing wall opening, the at least one opening in the first tubular member being axially displaced from the at least one opening in the second tubular member such that combustion products flow in the other one of the first axial direction and the second axial direction between the at least one opening in the second tubular member and the at least one opening in the first tubular member, the second axial direction being substantially opposite from the first axial direction;

    a third tubular member positioned within the second housing chamber, the third tubular member having at least one opening formed therein to enable fluid communication between an interior of the third tubular member and the at least one opening formed in the housing wall enabling fluid communication between the second chamber and the housing exterior;

    a fourth tubular member positioned within the third tubular member, the fourth tubular member including at least one opening formed therein to enable fluid communication between an interior of the fourth tubular member and the at least one opening formed in the third tubular member,the at least one housing wall opening enabling fluid communication between the second chamber and the housing exterior being axially displaced from the at least one opening in the third tubular member such that combustion products flow in one of the first axial direction and the second axial direction between the at least one opening in the third tubular member and the at least one housing wall opening, the at least one opening in the third tubular member being axially displaced from the at least one opening in the fourth tubular member such that combustion products flow in the other one of the first axial direction and the second axial direction between the at least one opening in the fourth tubular member and the at least one opening in the third tubular member,the first and second tubular members being positioned within the first chamber, and the third and fourth tubular members being positioned within the second chamber.
