  • Patent number: 8979121
    Abstract: A pyrotechnic inflator assembly including a shell member and an end cap joinable with the shell member to form a subassembly. The subassembly contains a quantity of pyrotechnic material and at least in part defines a combustion chamber wherein at least a portion of the quantity of pyrotechnic material is reactable to form product gas for inflation of an associated airbag cushion and to generate pressure therewithin. A diffuser assembly can be disposed adjacent an end of the shell member and includes flow control features for controlling flow of product gas from the inflator assembly. The inflator assembly further includes a composite overwrap about at least a portion of the subassembly and the diffuser assembly such that the pyrotechnic inflator assembly can withstand the pressure generated within the combustion chamber upon reaction of the pyrotechnic material. Corresponding methods of making a pyrotechnic inflator assembly are also provided.

  • Patent number: 8752486
    Abstract: Power sources and methods for applying a force to an object include use of thermite in a quantity sufficient to generate a thermite reaction, and a gas producing substance disposed in association with the thermite. The gas producing substance produces a gas when the thermite reaction occurs. The thermite reaction, the gas, or combinations thereof provide a force to the object. The gas can slow the thermite reaction to enable slower or continuous application of force while being non-extinguishing of the thermite reaction. The gas can further control heat transfer from the thermite reaction to adjacent objects.

  • Patent number: 8671842
    Abstract: A gas generator includes an outer wall delimiting a first chamber, a source of gas and a second chamber for diffusing gas outwards between which is found a nozzle. The nozzle includes a first through-hole for letting through gas from the first chamber to the second chamber. The first hole is closed by a cap capable of being opened from the triggering of an electro-pyrotechnic device located towards the first chamber. The second diffusion chamber includes in the wall at least one second through-hole for letting through gas outwards. The outer wall includes at least one overmolded plastic material around a portion of the metal nozzle.

  • Patent number: 8590930
    Abstract: A gas generator includes, an igniter having an ignition portion and a conductive pin a collar holding the igniter, a metallic cup-shaped case fixed to the collar and having a fragile portion. The collar includes a metallic portion and a resin part enclosing the ignition portion. An outer diameter of the metallic portion is larger than an outer diameter of the resin part. The cup-shaped case has an annular portion bent inward at an opening thereof. The annular bent portion includes a bent corner, an annular tilted surface, and an annular terminal end. The annular tilted surface includes an outer tilted surface facing toward a side of a peripheral surface of the cup-shaped case and an inner annular tilted surface facing the opposite side. The inner annular tilted surface of the annular bent portion presses against the resin portion.

  • Patent number: 8556294
    Abstract: An airbag inflator has a primary igniter and a secondary igniter. The primary igniter ignites an ignition enhancer material, which in turn ignites a primary supply of a gas generant material in a first chamber. A secondary supply of the gas generant material is located in a second chamber that is closed and is not in contact with any ignition enhancer material. Activation of the secondary igniter does not ignite the secondary supply of gas generant material, but does cause the second chamber to be opened. Combustion products from the primary supply of gas generant material enter the chamber and ignite the secondary supply of the gas generant material.
