ABSTRACT:
A gas generating system (10) including a baffle system (42) for modifying the temperature and pressure of a gas generated by the system, and to remove particulates from the gas. The gas generating system includes a first combustion chamber (34a), a second combustion chamber (36a), and the baffle system (42) adjacent both the first and second combustion chambers so as to enable fluid communication with the combustion chambers upon activation of the gas generating system. In another aspect of the present invention, a baffle system (42) is provided including a first end plate (44) having an opening (44b) formed therein for enabling fluid communication with a first fluid source (34a), a second end plate (46) having an opening (46b) formed therein for enabling fluid communication with a second fluid source (36a), and a sequence of baffle elements (48) extending between the first and second end plates. A first baffle element (48a) of the sequence of baffle elements defines a chamber (60) for receiving therein a fluid through the openings in the first and second end plates. Each additional baffle element in the sequence of baffle elements is spaced outwardly apart from a preceding baffle element in the sequence of baffle elements. In another aspect of the invention, a method is provided for producing, in a gas generating system, a gas having a pressure within a predetermined pressure range and a temperature within a predetermined temperature range. In another aspect of the present invention, a vehicle occupant protection system is provided.
