摘要： A multi-chamber gas generating system (10) has a housing (12) with openings (24) formed in a wall thereof. A gas-tight internal divider (42) separates the housing into two chambers (80, 80′). A gas generating sub-assembly (100) incorporating a baffle system is positioned in the first chamber (100). The sub-assembly (100) includes a first tubular member (44) and a second tubular member (52) positioned within the first member. The first and second members have openings (49, 54) formed therein to enable fluid communication between an interior of the second member (52) and the housing openings (24). The housing openings (24) are axially displaced from the first member opening (49) such that combustion products flow in a first axial direction between the first member opening and the housing opening. The first member opening (49) is axially displaced from the second member openings (54) such that combustion products flow in a second axial direction between the second member openings (54) and the first member opening (49). The second axial direction is substantially opposite from the first axial direction. A second sub-assembly (100′) in second housing chamber (80′) includes third and fourth tubular members (44′, 52′) similar to the first and second members and having openings therein axially displaced relative to each other such that combustion products flow in the second axial direction between the third member opening (49′) and the housing openings (24), and in the first axial direction between the fourth member openings (54′) and the third member opening (49′).

摘要： An airbag inflator (10) including an elongated outer housing (12) having an interior and one or more orifices (22) formed therealong to enable fluid communication between the outer housing interior and an exterior of the outer housing (12). The outer housing orifice(s) (22) open from the outer housing interior toward a first side (F) of the inflator. An elongated inner housing (14) is positioned in the outer housing interior. The inner housing (14) has an interior and one or more orifices (20) formed therealong to enable fluid communication between the inner housing interior and an exterior of the inner housing (14). The inner housing orifice(s) (20) open from the inner housing interior toward a second side (S) of the inflator. A quantity of a gas generant composition (16) extends along a portion of the interior of the inner housing (14). The gas generant (16) has a substantially “C”-shaped cross-section with a slot (24) extending along the length of the gas generant (16). The gas generant slot (24) is oriented facing the inner housing orifice(s) (20). A filter (15) is positioned intermediate the inner housing orifice(s) (20) and the outer housing orifice(s) (22) for filtering combustion products generated by combustion of the gas generant composition (16). An igniter (40) is operatively coupled to the gas generant composition (16) so as to enable fluid communication between the igniter (40) and the gas generant composition (16) upon activation of the inflator (10). The slotted, “C”-shaped cross section of the gas generant (16) provides a greater exposed gas generant surface area than would be achievable without the slot (24). This enhances the ignition and burning of the gas generant composition (16) upon inflator activation.
