Pyrotechnic compositions having combustion reaction products that include a high percentage of carbon dioxide at high temperatures. These pyrotechnic compositions include a fuel component having combustion product with a relatively high percentage of carbon to hydrogen content, such as an aromatic polycarboxylic anhydride fuel component. These pyrotechnic compositions may be employed to emit infrared radiation from a decoy flare or other device. The compositions may also be employed as a gas generating propellant for a projectile, such as a flare or rocket, or for other applications such as an automobile airbag. These pyrotechnic compositions emit infrared emissions with minimized short wavelength components, and produce substantially non-toxic combustion gases having relatively small amounts of water vapor.

Pyrotechnic compositions and uses therefore

Disclosed are compositions that are useful as microgas-generators, which can be used as propellants in airbags or seatbelt pretensioners. The compositions use a fuel which comprises an organic compound having a high ratio of the number of reactive carbon-oxygen groups to the total number of carbon atoms. The compositions also optionally use an oxidizer to supply oxygen to the fuel and/or a binding agent to form the fuel and optional oxidizer into particles. The compositions are useful as ignitors or squibbs, and can be used in industrial tools, seatbelt pretensioning systems, and airbags.

Combustible composition for use in vehicle safety systems

The invention relates to an electrical initiator which can be used with an automobile air bag or seat belt pretensioner. The initiator comprises a header, a cup, conducting pins, epoxy pin seals, a bridgewire, a primer, and an output charge. In some embodiments, the initiator also includes a director can. The header and the cup are composed of an insulating dielectric material capable of being ultrasonically welded together. The header secures the pins. Each pin is electrically conductive and each is formed with a buttress knurl to form a seal when each pin is inserted into the header. Additionally, the pins are further sealed to the header by an epoxy sealant and the interference fit of the pin to the header. The bridgewire connects the pins together on one side of the header. An electrical signal through the bridgewire generates heat igniting the primer. Primer reacts with the output charge that in turn ignites a solid gas generant that produces gas that fills air bags or activates the gas generator that drives seat belt pretensioners. The primer contacts the bridgewire. The output charge contacts the primer. The output charge is in the cup, and the cup is ultrasonically welded to the header to provide, along with the pin seals, an environmentally secure seal.
