First Claim
1. A gas generating system comprising:
- a gas generator for production of gas; and
a flame retardant positioned exterior to the gas generator, said flame retardant comprising at least one metal oxide,wherein upon activation of the gas generator, the gas is at least partially reactable with the flame retardant, and, said flame retardant is provided in a molar amount sufficient to oxidize a predetermined amount of carbon monoxide formed upon activation of said gas generator.

Abstract
A gas generating system (24) is provided including a gas generant container (34) and an initiator (28). The initiator (28) is positioned exterior of the gas generant container (34) so as to enable fluid communication with the container (34) upon activation of the initiator (28). A gas generant composition (32) is placed within the container (34). In one embodiment, the gas generant container (34) has sufficient rigidity to maintain a predetermined shape prior to positioning of the gas generant (32) therein, and is penetrable by combustion products resulting from activation of the initiator (28). A flame retardant (33) is positioned within the housing 17 exterior of the gas generant container (34) but in reactive proximity thereto. A seatbelt device (150) and a vehicle occupant restraint system (180) incorporating a gas generating system as described herein are also disclosed.
