Gas generating system
First Claim
1. A gas generating system comprising:
- a baffle system includinga first baffle chamber in fluid communication with a separate inflation gas generant combustion chamber for receiving therein combustion products from combustion of an inflation gas generant positioned in the combustion chamber; and
an outer baffle chamber positioned radially outwardly from the first baffle chamber for receiving therein combustion products from the first baffle chamber, anda second baffle chamber positioned radially inwardly of the outer baffle chanter for receiving therein combustion products from the outer baffle chamber.

Abstract
A gas generator (10) includes an igniter (27) and first and second inflation gas generant compositions (52, 52′) positioned to enable fluid communication with the igniter (27) upon activation of the igniter. Flow regulators (54, 54′) are provided to regulate a flow of combustion products from the igniter (27) to the first and second inflation gas generant compositions (52, 52′), to correspondingly regulate a time period between activation of the igniter (27) and initiation of combustion of the first and second inflation gas generant compositions (52, 52′). In another aspect, the gas generator (10) includes a modular baffle system (70) including a first baffle chamber (71) in fluid communication with an inflation gas generant combustion chamber (50) for receiving therein combustion products from combustion of an inflation gas generant (52) positioned in the combustion chamber. An outer baffle chamber (74) is also positioned radially outwardly from the first baffle chamber (71) for receiving therein combustion products from the first baffle chamber. In yet another aspect, the gas generator includes a first enclosure (12), a second enclosure (24), and a projection (44) formed on one of the first enclosure and the second enclosure. An aperture (46) is formed in the other one of the first enclosure (12) and the second enclosure (24) for receiving the projection (44) therein. At least a portion of the projection (44) is fixed within the aperture (46) to prevent withdrawal of the projection (44) from the aperture (46), thereby securing together the first enclosure (12) and the second enclosure (24).

3. A gas generating system comprising:
-
a modular baffle assembly including; an enclosure; and a plurality of discrete baffle elements positioned within the enclosure, each baffle element of the plurality of baffle elements being spaced apart from a wall of the enclosure to define a flow passage for an inflation fluid between each baffle element of the plurality of baffle elements and the wall, a first baffle element of the plurality of baffle elements defining a first baffle chamber, the first baffle chamber being in fluid communication with the flow passage, a second baffle element of the plurality of baffle elements defining a second baffle chamber, the second baffle chamber being in fluid communication with the flow passage, at least one of the first and second baffle chambers being positioned so as to enable fluid communication with an enclosure containing an inflation gas generant composition upon activation of the gas generating system. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10)

11. A gas generating system comprising a gas generator including:
-
a first enclosure; a second enclosure; a projection formed on one of the first enclosure and the second enclosure; and an aperture formed in the other one of the first enclosure and the second enclosure for receiving the projection therein, at least a portion of the projection being fixed within the aperture to prevent withdrawal of the projection from the aperture, thereby securing together the first enclosure and the second enclosure, the first enclosure comprising an igniter assembly and the second enclosure defining a combustion chamber for an inflation gas generating composition, the second enclosure being positioned so as to enable fluid communication with the first enclosure upon activation of the gas generator, and wherein the projection is formed on the second enclosure and an orifice is formed in the second enclosure extending through the projection to regulate the flow of a fluid between the first enclosure and the second enclosure.

12. A gas generating system comprising a gas generator including:
-
a first enclosure; a second enclosure; a projection formed on one of the first enclosure and the second enclosure; and an aperture formed in the other one of the first enclosure and the second enclosure for receiving the projection therein, at least a portion of the projection being fixed within the aperture to prevent withdrawal of the projection from the aperture, thereby securing together the first enclosure and the second enclosure; and wherein the aperture end at least a portion of the projection are dimensioned such that an interference fit is formed between the projection and the aperture when the projection is received within the aperture, to prevent withdrawal of the projection from the aperture.
