摘要： A gas generating system (10) includes a tubular outer housing (12) having a longitudinal axis (L) and one or more apertures (12d) formed therealong to enable fluid communication between an interior of the outer housing and an exterior of the outer housing. A tubular inner housing (70) is positioned within the interior of the outer housing (12). The inner housing (70) includes one or more apertures (70d ) formed therealong to enable fluid communication between an interior of the inner housing and an exterior of the inner housing. A first tubular baffle (80) is provided for cooling and regulating a flow of gas produced by the gas generating system (10). The first baffle (80) has a plurality of corrugations (80c) formed therealong and is positioned between the inner housing (70) and the outer housing (12) to define a gas flow channel (82) extending between the first baffle (80) and the inner housing (70). The first baffle also includes an opening (80e) formed therein to enable fluid communication between the gas flow channel (82) and an exterior of the gas flow channel. The corrugations (80c) are spaced apart from the inner housing (70) to provide a corresponding plurality of constricted gas flow passages (84) extending between the corrugations (80c) and the inner housing (70). The constricted passages (84) provide alternating compression and expansion of gases flowing along the gas flow channel (82), thereby facilitating cooling and filtration of the gases.

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： A filterless airbag module (10) including a structure for cooling combustion gases. The airbag module (10) includes an inflator (12) having a housing (18) and a smokeless gas generating propellant (20) contained within the housing. One or more apertures (24) are formed in the housing (18) to enable fluid communication between an interior of the housing and an exterior of the housing. An airbag (16) is arranged to fluidly communicate with the apertures (24). A combustion gas retainer (42) is positioned exterior of the housing (18) and in alignment with the apertures (24). The retainer (42) and a surface (72) of the housing (18) combine to define a cooling chamber (50) for cooling combustion gases received from the housing (18) via the apertures (24). The cooling chamber (50) is dimensioned to affect an average residence time of combustion gases received in the chamber (50) so that the gases reside in the cooling chamber (50) for a length of time sufficient to cool the gases to a temperature within a predetermined temperature range prior to the gases exiting the cooling chamber (50). A heat-absorbing material may be positioned in the cooling chamber (50) to aid in cooling combustion gases received therein.

摘要： Preferred gas generant compositions incorporate a combination of 5-aminotetrazole nitrate and an oxidizer. The oxidizer may be selected from a group including nonmetal and metal nitrates, nitrites, chlorates, chlorites, perchlorates, and oxides. 5-aminotetrazole nitrate is characterized as an oxygen-rich fuel and is therefore considered to be a self-deflagrating fuel. To tailor the oxygen balance in certain applications, however, the use of an oxidizer is preferred. Methods of formulating the compositions are also described. These compositions are especially suitable for inflating air bags and actuating seatbelt pretensioners in passenger-restraint devices.

摘要： An inflator (10) for use in an inflatable vehicle occupant protection system. The inflator (10) includes a pressure vessel (12) having an opening (60) formed therein. A quantity of relatively unreactive pressurized gas is stored in the pressure vessel (12). A quantity of a gas generant composition (14) is positioned in an interior of the pressure vessel (12) and in fluid communication with the pressurized gas. An igniter (18) is positioned proximate the gas generant (14) for initiating combustion of the gas generant. A rupturable, fluid-tight seal (30) is positioned to seal the opening (60) in the pressure vessel (12) for maintaining the pressurized gas within the pressure vessel (12) prior to activation of the igniter (18). Activation of the igniter (18) results in combustion of the gas generant (14). Pressure from the combustion gases, in combination with the pressure of the gases stored under pressure in vessel (12), cause the burst disk (30) to rupture, providing an inflation gas to an associated vehicle airbag, for example. Also provided is a method for manufacturing an inflator for use in an inflatable vehicle occupant protection system.

摘要： An inflator (10) for use in an inflatable vehicle occupant protection system is provided. In one aspect of the invention, the inflator (10) includes a longitudinal enclosure (22) having a substantially uniform cross-sectional area along at least a portion of the enclosure, and a gas generant composition (24) positioned along the portion of the enclosure (22). The gas generant composition (24) is distributed substantially uniformly along the portion of the enclosure (22). A plurality of gas exit apertures (40) is formed along the portion of the enclosure (22) to enable fluid communication between the enclosure (22) and an exterior of the enclosure. The apertures (40) are spaced apart a distance proportional to a desired rate of propagation of a combustion reaction of gas generant positioned between the apertures (40). In another aspect of the invention, the total number of apertures (40) along the enclosure (22) is inversely proportional to a desired rate of propagation of a combustion reaction of gas generant positioned between the apertures (40). In yet another aspect of the invention, an airbag device is disclosed which includes an inflator having an inflator housing (12) configured as a structural member of a vehicle. The inflator housing may be employed as a stand-alone structural member in a vehicle or used to reinforce another structural member. The housing may comprise a cavity portion having a cylindrical cross-section. The cavity portion may serve as the structural member, or extensions (150) may be coupled to the cavity portion to provide a structural member having a desired configuration. Examples of vehicle components employing the inflator (22) as a structural enhancement include seats, doors, and instrument panels.
