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.
摘要翻译：热稳定的气体发生剂组合物包含硝基胍，一种或多种非偶氮高氮燃料和相稳定的硝酸铵或类似的非金属氧化剂的组合，其在燃烧时导致每质量单位气体发生剂产生更高的气体产物产率，固体燃烧产物的产率降低，可接受的燃烧速率，热稳定性和弹道性能。这些组合物特别适合于在乘客约束装置中充气气囊。

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.
摘要翻译：优选的气体发生剂组合物包含5-氨基四氮唑硝酸盐和氧化剂的组合。氧化剂可以选自包括非金属和金属硝酸盐，亚硝酸盐，氯酸盐，亚氯酸盐，高氯酸盐和氧化物的组。 5-氨基四氮硝酸盐的特征在于富氧燃料，因此被认为是自燃燃料。然而，为了在某些应用中调节氧平衡，优选使用氧化剂。这些组合物特别适用于在乘客约束装置中充气气囊和致动安全带预紧器。

摘要： An autoignition composition for the gas generator of a vehicle occupant restraint system that is thermally stable at temperatures up to 110.degree. C., autoignites between 150.degree. C. and 175.degree. C., produces minimal toxic gases upon combustion, provides for a reduced gas inflator size, and can be safely produced using simple processing methods. By mixing an alkali metal nitrite with a nitrogen-based fuel, the resulting gas generants autoignite at or below 175.degree. C. The addition of an alkaline earth metal nitrite or nitrate provides the stability needed to additionally function as a booster and/or a gas generant.

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： In accordance with the present invention, a flexible gas generator (10) is provided which includes a first flexible housing (14) defining an interior, the first housing (14) having an exterior surface. A first flexible, porous covering (15) is positioned in contact with substantially the entire exterior surface of the first housing (14). The first housing (14) and covering (15) are positioned within a second flexible housing (12). The first (14) and second (12) housings may be formed from polymeric or metallic tubing. A second flexible, porous covering (19) may be positioned to cover substantially the entire exterior surface of the second housing (12). The flexible first covering (15) may comprise multiple layers of, for example, a braided or a mesh material. The flexible coverings (15, 19) provide structural support for the housings (12, 14) while cooling and filtering the generated gases. A series of plenums (390) may be formed between adjacent layers of the first covering and/or a series of baffles (100) may be positioned between the layers to direct the flow of inflation gases and to cool the gases. Use of flexible tubing and flexible coverings provides the gas generator with substantial flexibility.

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.
