1. A gas generating composition which when ignited produces gas to inflate an inflatable vehicle occupant protection consisting essentially of:

  • a non-azide nitrogen containing organic fuel selected from the group consisting of guanidine nitrate, triaminoguanidine nitrate, and mixtures of guanidine nitrate and triaminoguanidine nitrate;

    an inorganic salt oxidizer;

    a burn rate modifier selected from the group consisting of cyclotetramethylenetetranitramine, cyclotrimethylenetrinitramine, iron oxide and mixtures thereof;

    0 to about 10% by weight of a non-energetic binder; and
