摘要： The invention, which is especially useful for inflating safety cushions for automotive vehicles, is essentially an orificed housing and an expendable cartridge therein. The cartridge has a hermetically sealed can containing a layer of gas generant material in one end contiguous with a tubular-shaped igniter including an electric squib and pyrotechnic material to be ignited thereby. A layer of filter screens is included between the ignition device and a perforated partition. The remainder of the can is filled with an annulus formed by annular wrappings of wire screen and a central bag of pH neutralizing material. The perforations in the partition are centered over the neutralizing material so that the slightly alkaline gases from the burning gas generant and ignition device must pass through the pH neutralizing material before passing through the annular wrappings of screen and rupturing the wall of the can to inflate a safety cushion. This disposable cartridge is closely supported on all sides by the housing, except at the orifices thereof, so that rupturing of the can may occur only at the orifices when the gas generator is fired.
摘要翻译：特别适用于对汽车的安全垫充气的本发明基本上是一个有孔的外壳和一个消耗性的卡盘。墨盒具有气密密封的罐，其容纳一层气体发生剂材料，其一端与管状点火器邻接，该管状点火器包括电点火器和由此引燃的烟火材料。点火装置和穿孔隔板之间包括一层滤网。罐的其余部分填充有由丝网的环形包装和pH中和材料的中心袋形成的环。分隔件中的穿孔位于中和材料的中心，使得来自燃烧气体发生剂和点火装置的轻微碱性气体必须通过pH中和材料，然后通过筛网的环形包装并破裂罐壁以使其膨胀安全垫除了在其孔口之外，这种一次性盒被壳体紧密地支撑在所有侧面上，使得当气体发生器被点火时罐的破裂只能在孔口处发生。
