摘要： Methods of making and resultant compositions thereof, which include a gas generant having a coating including an inorganic combustion inhibitor. Such coated gas generants are useful in pyrotechnic compositions and ignition materials, and may be employed, for example, in inflatable restraint systems. The ratio of coated and uncoated gas generant bodies within an airbag inflator may be tailored to provide S-curve inflation performance. Spray application of aqueous mixture including the combustion inhibitor onto the gas generant body provides a rapid way to achieve a thin but robust coating.

摘要： Compositions and methods relate to gas generants used in inflatable restraint systems. The gas generant grains include a fuel mixture having at least one fuel and at least one oxidizer, which have a burn rate that is susceptible to pressure sensitivity during combustion. The gas generant composition further includes a plurality of pressure sensitivity modifying glass fiber particles distributed therein to lessen the pressure sensitivity and/or to increase combustion stability of the gas generant. Such gas generants can be formed via spray drying techniques.

摘要： An inflator assembly having an inflator body that forms a chamber wherein a quantity of a gas generating solid reacts to form gas. A quantity of gas treatment material is included to treat the formed gas to form a treated gas. At least one assembly exit opening permits the treated gas to exit the inflator assembly. The required gas generating solid has a flame temperature of no more than 1670 K with the inflator assembly having significant weight and volume reductions as compared to an otherwise identical performing inflator assembly that utilizes gas generating composition having higher flame temperatures.

摘要： An inflator that includes a quantity of gas generant housed within a chamber. A liquid including at least one of a fuel soluble in the liquid or an oxidizer soluble in the liquid and a piston are housed within another chamber of the inflator. This chamber is sealed. Upon actuation, movement of the piston hydraulically expels the liquid through an opening in the piston such that the liquid contacts the gas formed by combustion of the gas generant and cools the same. The fuel and/or oxidizer in the liquid can react to form additional gas.

摘要： The disclosure provides an inflator device for a passive restraint device, like an airbag. In certain aspects, a fuel-rich gas generant grain is located in actuating proximity to an initiator device. The grain has at least one flow channel through which a shock wave generated by the initiator device passes. The shock wave opens a burst disc between the inflator housing and downstream airbag to permit gases to flow into the airbag. A chamber storing pressurized gas (having at least one oxidant, e.g., O2) is also disposed within the inflator. Upon initiator actuation, the oxidant can react with combustion products of the initiator and the fuel-rich gas generant and flow into the airbag for rapid inflation. Methods of inflating airbags and improving airbag deployment reliability are provided. Such inflators are particularly suitable for large volume (greater than 60 liter) airbags.
