摘要： The present invention provides an airbelt inflator (10) designed primarily for supplying and directing gas from the combustion of gas generant materials into a vehicle airbelt. Inflator (10) includes a substantially cylindrical inflator body (12), having a first end (11) and a second end (13). A unique booster cup (22) is positioned within inflator body (12), and is preferably press fit with initiator body (15), suspending cup (22) within inflator body (12). Cup (22) facilitates consistent burn of the main propellant, imparting repeatable bag performance. A cylindrical mesh filter (38) is positioned in inflator body (12). A nozzle (36) is preferably positioned adjacent a disc (30). A variety of different nozzles giving inflator (10) varying gas output characteristics can be utilized with inflator (10), for example thrusting inflators or thrust-neutral inflators, depending on the operating requirements of the airbelt system. Booster cup (22) is sized such that it extends into inflator body (12), and abuts filter (38), thereby serving as a stand off or locator for filter (38), and providing a relatively snug packing arrangement for propellant tablets (28).

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 first 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 a combustion chamber of the sub-assembly and the housing openings (24). The first sub-assembly openings (49, 54) are axially displaced from the housing openings (24) such that combustion products flow in opposing first and second axial directions between the first sub-assembly combustion chamber and the housing openings. A second sub-assembly (100′) of substantially identical construction is positioned in the housing second chamber (80′).

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： Thermally stable gas generant compositions incorporate a combination of one or more primary nonazide high-nitrogen fuels selected from a group including tetrazoles, bitetrazoles, and triazoles, and salts thereof; and one or more secondary nonazide high nitrogen fuels selected from azodicarbonamide and hydrazodicarbonamide. The primary and secondary fuels are combined with phase-stabilized ammonium nitrate that when combusted, results in a greater yield of gaseous products per mass unit of gas generant, a reduced yield of solid combustion products, lower combustion temperatures, and acceptable burn rates, thermal stability, and ballistic properties. These compositions are especially suitable for inflating air bags in passenger-restraint devices.

摘要： High nitrogen nonazide gas compositions, useful in inflating passenger restraint gas inflator bags, comprise a nonmetal salt of triazole or tetrazole fuel, phase stabilized ammonium nitrate (PSAN) as a primary oxidizer, a metallic second oxidizer, and an inert component such as clay or mica. The combination of these constituents results in gas generants that are relatively more stable and less explosive, have improved ignitability and satisfactory burn rates, have sustained combustion throughout the various combustion pressures at the inflator level, and generate more gas and less solids than known gas generant compositions.

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

摘要： An inflator 10 of a vehicle occupant protection system contains an elongated housing 12 having a plurality of gas exit orifices 14 spaced along the length thereof. An ignition body 30 and propellant 16 are provided in lengths substantially equivalent to the length of the housing 12 wherein the ignition body 30 is placed in physical contact with the propellant body 16 for all or most of their respective lengths. Once the ignition body 30 is ignited upon a crash event, resultant uniform ignition and combustion across the length of the propellant 16 results in uniform gas generation and uniform inflation of an airbag 26, wherein the airbag 26 is at least substantially coextensive with and in fluid communication with the housing 12. Preferred mixtures of propellant 16 contain silicone, a perchlorate oxidizer, and a coolant.
