摘要： An air bag inflator for the passenger side of an automobile includes an elongated, tubular housing having a plurality of perforations in its cylindrical wall for discharging gas. Within the housing are a gas generant composition, an igniter and filtering screens. The perforations are normally sealed with 0.003 inch (0.0762 mm.) thick non-tempered aluminum foil which is easily ruptured by the gas pressure when the inflator is ignited. The foil, in addition to serving as a hermetic seal for protecting the gas generant and igniter from moisture and dust, insures that the gas pressure will reach a certain, threshold level before being discharged into an air bag. In very cold weather the inflator attains its peak pressure considerably more slowly than in warm weather. As a result, the air bag may be inflated either too slowly or insufficiently to perform its intended purpose. In order to preclude this from happening at least some of the perforations in the housing are covered with an additional or buttressing layer of thicker (0.006 inch; 0.1524 mm.) non-tempered aluminum foil, so that the threshold gas pressure necessary to rupture these seals is raised. This shortens the time for attaining peak gas pressure within the tubular housing and results in faster, more satisfactory inflation of the air bag when the ambient temperature is low.
摘要翻译：用于汽车乘客侧的气囊充气机包括细长的管状壳体，其在其圆柱形壁中具有用于排放气体的多个穿孔。在壳体内是气体发生剂组合物，点火器和过滤网。穿孔通常用0.003英寸（0.0762mm。）厚的非回火铝箔密封，当充气机被点燃时，其易于被气体压力破裂。该箔除了作为气体密封件用于保护气体发生剂和点火器的湿气和灰尘之外，确保气体压力在排放到气囊中之前将达到一定的阈值水平。在非常寒冷的天气下，充气机的高峰压力比在炎热的天气中慢得多。结果，气囊可能太慢或不充分地膨胀以实现其预期目的。为了防止这种情况发生，壳体中的至少一些穿孔被较厚（0.006英寸; 0.1524mm）的非回火铝箔的附加或支撑层覆盖，使得破裂这些所需的阈值气体压力密封件被抬起。这缩短了在管状壳体内获得峰值气体压力的时间，并且导致当环境温度低时气囊的更快，更令人满意的膨胀。

摘要： A solid fuel gas generator generates extremely clean odorless nitrogen gas by a combustion process that involves the burning in an annular combustion chamber having gas discharge orifices of a gas generant composition having combustion product residues including alkali metal oxides and hydroxides and which may also include iron particulates, and features the provision between the composition and the gas discharge orifices of an annular primary cooling and filtering pack in the combustion chamber for maximum retention therein of such combustion product residues, the cooling and filtering pack including a fine mesh screen surrounding the gas generant composition and one or more layers of fiberglass woven fabric around the screen, the fabric being selected for its characteristic property at the combustion chamber temperature of reacting with the caustic soda in the combustion products to form innocuous sodium silicate and of becoming tacky to enhance particle entrapment, and further features in surrounding relation to the combustion chamber an annular secondary cooling and filtering pack including an aluminum silicate blanket that reacts with caustic soda residue to form innocuous sodium silicate.

摘要： A gas generator for inflating safety cushions in automotive vehicles has a tubular housing, closed at both ends except for a discharge orifice in one end. A hermetically sealed container in the completely closed end of the housing is divided by a consumable partition into two chambers containing gas generant material. Each of the two chambers is also equipped with an ignition means for igniting the gas generant. The remainder of the tubular housing is filled with the following elements, arranged in tandem series from the sealed container to the orifice of the housing: a filtering means, a first perforated plate, pH neutralizing material, a second perforated plate, cooling means, and a third perforated plate. An impact sensor, which is not a part of the present invention, determines whether one or both of the ignition means are fired on impact, depending upon the force of a collision; and, hence, the rate at which an inflatable structure is filled with gas.

摘要： A gas generator for automobile gas bags and the like includes a grain wherein a plurality of wafers of combustible gas generating material is arranged in a side by side array and a plurality of meshed cushion members is disposed in alternating relation between the wafers and compressed between the wafers in order to provide improved burn surface neutrality for more uniform inflator gas flow and better utilization of the gas generant, increased retention of solid residue in the combustion chamber for reduced plugging of the gas filters and cleaner inflation gas, a higher volumetric loading fraction so that the size and weight of the inflator may be reduced, and structural suspension of each individual wafer between the adjacent compressed cushion members to reduce breakage and damage of the wafers during the many years the inflator may remain in an automobile.

摘要： A gas generant composition especially adapted for inflating automotive airbags in the event of a vehicle collision to protect the occupants of the vehicle from injury. The composition consists essentially of 65-74% alkali metal azide; 10-28% ferric oxide; 6-16% sodium nitrate; 0.1-2% fumed silica; and 0-2% molybdenum disulfide. The composition burns at from about 1.2 to about 1.7 inches per second (about 3.0 to about 4.3 cm/sec).

摘要： For an inflator for pyrotechnically inflating protective gas bags for vehicles, an igniter is provided which causes the propellant in the inflator to ignite in a progressive manner so as to inflate the bag slowly at the onset but more rapidly later as inflation progresses. The overall inflation time is very rapid but the slow onset of bag deployment starts gentle movement against a vehicle's occupant and thus reduces the possibility of injury as compared with a more sudden movement by rapid inflation from the outset.

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.
