    摘要： A gas generant tablet (24) for use in a linear inflator (10). The tablet (24) includes a body portion (102) having a first end (104), a second end (106), and a longitudinal axis (T). A first projection (108) extends from the tablet first end (104) in a first direction, with at least a portion of the first projection (108) extending non-orthogonally with respect to the tablet longitudinal axis (T). A second projection (112) extends from the tablet second end (106) in a second direction generally opposite the first direction. At least a portion of the second projection (112) extends non-orthogonally with respect to the tablet longitudinal axis (T). The tablet (24) is shaped such that a cavity (25) is formed between adjacent tablets (24) when the tablets are stacked within a combustion chamber of the inflator (10). Also disclosed is an inflator (10) for use in an inflatable vehicle occupant protection system (200). The inflator (10) includes a longitudinal enclosure (22) having a substantially uniform cross-sectional area along at least a portion of the enclosure. The enclosure (22) defines an interior cavity (22c) for containing a quantity of a gas generant composition therein, and includes a plurality of apertures (40) formed therealong to enable fluid communication between the enclosure interior cavity (22c) and an exterior of the enclosure. A plurality of gas generant tablets (24) is stacked along the enclosure (22), the tablets being shaped such that a cavity (25) is provided between adjacent tablets (24) when the tablets are stacked within the enclosure (22).

    摘要： An inflator (10) for use in an inflatable vehicle occupant protection system. 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 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 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).

    摘要： A pyrotechnic actuator 10 contains a tapered piston 30 that is first propelled through a chamber 18 upon actuator 10 operation. A narrower portion 38 of the piston 30 initially enters an annular retainer 40 having an annulus 42. The diameter or cross-sectional area of the annulus 42 is about equal to or less than the cross-sectional area of portion 38. As the diameter of the tapered piston 30 increases over the length passing through retainer 40, to a diameter greater than that of annulus 42, the piston 30 is then wedged or fixedly received within the annular retainer 40, thereby preventing retraction of piston 30 once a load is exerted thereon.

    摘要： Thermally stable gas generant compositions incorporate a combination of nitroguanidine, one or more nonazide high-nitrogen fuels, and phase-stabilized ammonium nitrate or a similar nonmetallic oxidizer that, upon combustion, result in a greater yield of gaseous products per mass unit of gas generant, a reduced yield of solid combustion products, and acceptable burn rates, thermal stability, and ballistic properties. These compositions are especially suitable for inflating air bags in passenger-restraint devices.

    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. These compositions are especially suitable for inflating air bags and actuating seatbelt pretensioners in passenger-restraint devices.
