1. A gas generator comprising: a housing containing a first end and a second end;a perforated first combustion chamber contained within said housing;a second combustion chamber contained within said housing, said second combustion chamber containing at least one gas exit aperture proximate to said second end of said housing;a first gas generant contained within said first combustion chamber;a second gas generant contained within said second combustion chamber;a first gas generant cushion positioned between one of either the first end or the second end, and the first gas generant, the first gas generant cushion including a first inner wall, a second inner wall, and at least a first concave cavity defined within at least one of the first inner wall and the second inner wall; anda booster chamber contained within said housing and extending from said first end to said second end, said booster chamber extending through said first gas generant cushion and in physical communication with said second end of said housing. 2. The gas generator of claim 1 wherein said first combustion chamber extends from said first end to said second end, through said first gas generant cushion, and in physical communication with said second end. 3. The gas generator of claim 1 wherein said at least one gas exit aperture of said second combustion chamber is sealed with at least one removable plug prior to actuation of said gas generator. 4. The gas generator of claim 1 wherein said first gas generant cushion is contoured about a portion of a periphery of said second combustion chamber. 5. The gas generator of claim 1 wherein said first gas generant cushion comprises said first concave cavity defined within said first inner wall and a second concave cavity defined within said second inner wall. 6. The gas generator of claim 1 wherein said first gas generant cushion comprises said at least first concave cavity defined within said first inner wall and said second inner wall. 7. A gas generator comprising: a housing containing a first end and a second end;a perforated first combustion chamber contained within said housing;a first gas generant contained within said first combustion chamber;a first gas generant cushion positioned between one of either the first end or the second end, and the first gas generant, the first cushion defining at least a first blind cavity therein; anda booster chamber contained within said housing, said booster chamber extending through said first gas generant cushion and in physical communication with said second end of said housing. 8. The gas generator of claim 7 wherein the at least a first cavity opens in a direction toward the one of either the first end or the second end. 9. The gas generator of claim 7 further comprising: a second combustion chamber contained within said housing; anda second gas generant contained within said second combustion chamber. 10. The gas generator of claim 9 wherein said second combustion chamber extends through said first gas generant cushion and physically communicates with said second end. 11. The gas generator of claim 7 wherein the first blind cavity is interposed between the first gas generant and the one of either the first end or the second end. 12. The gas generator of claim 7 wherein said first gas generant cushion is formed in the shape of an annulus or donut. 13. The gas generator of claim 7 wherein said first gas generant cushion comprises a first inner wall and a second inner wall, and wherein the at least a first cavity is defined within at least one of the first inner wall and the second inner wall. 14. The gas generator of claim 13 wherein said first gas generant cushion comprises said first cavity defined within said first inner wall and a second blind cavity defined within said second inner wall. 15. The gas generator of claim 7 wherein said first gas generant cushion is formed from desiccant and silicone. 16. A gas generator comprising: a housing containing a first end and a second end;a perforated first combustion chamber contained within said housing;a first gas generant contained within said first combustion chamber; anda first gas generant cushion positioned between one of either the first end or the second end, and the first gas generant, said first gas generant cushion comprising a first inner wall, a second inner wall, and at least a first concave cavity defined within said first inner wall and/or said second inner wall. 17. The gas generator of claim 16 further comprising: a booster chamber contained within said housing, said booster chamber extending through said first gas generant cushion and in physical communication with said second end of said housing. 18. The gas generator of claim 16 wherein said first gas generant cushion comprises said first concave cavity defined within said first inner wall and a second concave cavity defined within said second inner wall. 19. A vehicle occupant protection system comprising the gas generator of claim 16.
