    摘要： Airbag inflators employ gas generating compositions formed from a mixture of fuels and a mixture of oxidizers and preferably mica at levels of 1 to 5% by weight. The gas generant composition contains a primary and secondary fuel. The primary fuel is a guanidine compound, preferably guanidine nitrate. The secondary fuel is selected from tetrazoles, triazoles and mixtures thereof at levels of 5% by weight or less of the total gas generant composition. The oxidizer system is a mixture of at least two components selected from the group consisting of transition metal oxides, alkali metal nitrates and alkaline earth metal nitrates. The novel gas generants yield inflating gases having a reduced content of undesirable gases such as nitrous oxides and carbon monoxide.

    摘要： A low onset dual stage hybrid inflator comprising a diffuser subassembly, a gas generator subassembly, and a pressure vessel. The dual stage inflator offers a variety of different output levels of inflation gas. The four main deployment scenarios for the dual stage inflator are primary output, staged output, full output, and secondary only. For primary output, only the stored gas is released from the inflator. For staged output, the stored gas is released and after a short period of time (i.e. 30 ms), the gas generant is ignited. For the full output, the stored gas is released from the dual stage inflator at the same time the gas generant is ignited. For secondary output, only the gas generant subassembly is fired, and the hot gases from the gas generant subassembly mix with the stored gas. The combination of the hot gas and the stored gas has sufficient pressure to rupture the burst disk.

    摘要： A non azide gas generant composition of nitroguanidine and an oxidizer such as phase stabilized ammonium nitrate is provided. A gas generant having nitroguanidine and phase stabilized ammonium nitrate has many desirable characteristics such as little production of ash and the production of essentially toxic free exhaust gas. When nitroguanidine is compressed into a pellet it has needle shaped crystals that bend or distort. When the gas generant pellets are subjected to thermal cycling some nitroguanidine crystals will return to their native conformation resulting in pellet growth. To eliminate this pellet growth, nitroguanidine is passed through a vibrating ball mill. The media in the vibrating ball mill pulverizes the nitroguanidine into an amorphous crumb.

    摘要： An initiator has a circuit board with two spaced copper traces and a bridge resistor of Nichrome® or tantalum nitride at one end, and wire leads or pins joining the wire traces at the other end. A zener diode is placed between the wire leads and a bridge resistor. Immediately before the wire leads reach the circuit board they pass through a ferrite core. The wire leads, the ferrite core, and the circuit board except for the end of the board to which the bridge resistor is mounted, is insert molded into a body of glass filled nylon 6,6. The nylon body mounts an aluminum can that covers the bridge resistor and is bonded to a circumferential groove in the nylon body. The bridge resistor is covered with primary explosives such as zirconium potassium perchlorate and the can is filled with gas generating granules such as 5-aminotetrazole.

    摘要： The dual stage inflator has a divider plate that separates gas generant in the primary chamber from gas generant in the secondary chamber. Burning of the gas generant yields inflation gas that is useful for inflating a vehicle airbag. The gas generant from the primary chamber is ignited from a separate ignition train than the gas generant in the secondary chamber. The divider plate in the inflator is capable of moving during the operation of the inflator. Before the inflator is fired, the divider plate rests against the inner surface of the lower housing. The divider plate prevents inflation gas from the primary chamber from igniting the secondary chamber. However, when the internal pressure of the secondary chamber exceeds the internal pressure of the primary chamber, the divider plate is displaced in an upward direction thereby permitting the inflation gas from the secondary chamber to flow around the divider plate and out of the inflator.
