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.

摘要： Selective non-catalytic reducing (SNCR) compounds, independent of the gas generant composition, reduce the toxicity of effluent gases produced by combustion of nonazide gas generating compositions used to inflate vehicle occupant restraint systems. It is believed that reaction of the NH2 radical (formed from the SNCR compound) with NO in the combustion gas forms N2 thereby decreasing the concentration of toxic nitrogen oxides therein. Heterogeneous placement of the reducing compound proximate to the gas generant bed within a gas generator ensures intimate contact with the combustion gases, and yet still provides a noninvasive method of toxic gas reduction.
摘要翻译：选择性非催化还原（SNCR）化合物，独立于气体发生剂组合物，降低了用于使车辆乘员约束系统膨胀的非偶氮气产生组合物燃烧产生的废气的毒性。相信在燃烧气体中NH 2自由基（由SNCR化合物形成）与NO的反应形成N 2，从而降低其中的有毒氮氧化物的浓度。在气体发生器内靠近气体发生床的还原性化合物的非均匀放置确保与燃烧气体的紧密接触，但仍然提供无毒的气体还原方法。

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. A first propellant body 31 and a second propellant body 33 are provided in lengths substantially equivalent to the length of the housing 12 wherein the first propellant body 31 is placed in physical contact with the second propellant body 33 for all or most of their respective lengths. Once the first propellant body 31 is ignited upon a crash event, resultant uniform ignition and combustion across the length of the second propellant body 33 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 first propellant body 31 contain silicone, a perchlorate oxidizer, and a nitrate salt.

摘要： Assembly of a gas generator 10 includes the step of adding uncured silicone to a propellant cup 25. Granulated oxidizer is then added over the top of the silicone and allowed to disperse therein. Afterwards, the silicone is cured to provide flush communication with an inner wall 14 of the propellant cup 25. Other granulated gas generant constituents may be added as well. A gas generator 10 assembled in this manner provides more predictable burn rates of a gas generant composition 26 and therefore more predictable performance of the gas generator 10.

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： An inflator (10) for use in an inflatable vehicle occupant protection system. The inflator (10) includes a longitudinal enclosure (22) and a first gas generant (24) positioned along the enclosure (22). Enclosure gas exit apertures (40) are arranged along the enclosure (22) to enable fluid communication between the enclosure (22) and an exterior of the enclosure. And to provide controlled venting of combustion gases from the enclosure (22) as the first gas generant composition (24) burns, thereby controlling the speed and direction of combustion propagation of the first gas generant. Combustion of the first gas generant (24) results in an inflator housing internal pressure of at least a first predetermined minimum internal pressure. The second gas generant composition (91) is also configured to combust to generate inflation gas providing at least a second predetermined minimum internal pressure in the housing, the second predetermined minimum internal pressure being higher than the first predetermined minimum internal pressure. As combustion of first gas generant (24) nears completion, flame from combustion of the first gas generant composition (24) reaches the end (22b) of the enclosure (22) and contacts the second gas generant composition (91), igniting the second gas generant (91) and producing a burst of gas and a resulting in an increase in inflator housing internal pressure. Gas exit apertures (20) along the housing (12) are sized such that the housing internal pressure is maintained at at least the first predetermined minimum level after passage of a predetermined time period after inflator activation.
