초록

A gas generating composition comprising ammonium nitrate and a non-toxic metal oxide which reduces the pressure exponent and enables the composition to sustain combustion at or near atmospheric pressure, thereby improving combustion efficiency. The composition is useful for various purposes, such as inflating a vehicle occupant restraint, i.e., an air bag for an automotive vehicle or aircraft, as well as aircraft escape chutes or the like.

청구항

[ What is claimed is:] [1.] A gas generating composition comprising a mixture of:ammonium nitrate,guanidine nitrate and/or aminoguanidine nitrate; anda non-toxic iron oxide having a surface area of between about 5 m.sup.2 /gm to about 1000 m.sup.2 /gm, and being present in an amount between about 0.25 to 10 % by weight of the composition sufficient to achieve sustained combustion at atmospheric pressure and improved cold temperature combustion efficiency.
