GN, AGN and KP gas generator composition
First Claim
1. A gas generative composition for inflating inflatable passenger restraint devices consisting essentially of a solid solution of a) about 35 to about 50% by weight guanidine nitrate (GN), b) about 10 to about 30% by weight aminoguanidine nitrate (AGN), c) about 30 to about 40% by weight potassium perchlorate (KP), d) 0 to about 6% by weight potassium nitrate (KN) and e) 0 to about 5% by weight polyvinyl alcohol (PVA).

Abstract
The combination of guanidine nitrate (GN), aminoguanidine nitrate (AGN) and potassium perchlorate (KP) in defined proportions serves as an effective gas generative composition that displays enhanced burning rate performance at 2000 and 4000 psi. Through the addition thereto of small amounts of potassium nitrate (KN) the burning rate and pressure component of the composition is further improved and through the addition of polyvinyl alcohol (PVA) both greater dimensional strength and superior stability are provided.
