1. In a vehicle occupant protection system containing a binderless gas generant composition formed into a desired shape, the improvement comprising: a silicone coating applied about the gas generant composition, said coating provided at 1-50% by weight relative to the combined weight of the gas generant composition and silicone. 2. A product formed from the method comprising the steps of: providing powdered gas generant constituents including a fuel and an inorganic oxidizer, but not an elastomeric binder; homogeneously wet or dry blending the gas generant constituents; forming the gas generant blend into desired shapes; coating the gas generant shapes with uncured silicone; and curing the silicone covered shapes. 3. A nonazide gas generant composition comprising a nitrogen-containing fuel and an inorganic oxidizer, said composition formed into a desired shape, wherein the composition further comprises: a silicone coating about the desired shape, said silicone provided at 1-50% by weight relative to the combined weight of the gas generant composition and the silicone. 4. The gas generant composition of claim 3 wherein: said nitrogen-containing fuel is selected from the group consisting of tetrazoles, bitetrazoles, triazoles, triazines, guanidines, and metal and nonmetal salts and derivatives of the foregoing fuels, and mixtures thereof; and said inorganic oxidizer is selected from the group of nonmetal or metal nitrates, nitrites, chlorates, chlorites, perchlorates, oxides, and mixtures thereof. 5. The gas generant composition of claim 4 wherein: said nitrogen-containing fuel is selected from the group consisting of nitroguanidine, guanidine nitrate, aminoguanidine nitrate, 1H-tetrazole, 5-aminotetrazole, 5-aminotetrazole nitrate, 5-nitrotetrazole, 5,5'-bitetrazole, diguanidinium-5,5'-azotetrazolate, nitroaminotriazole, melamine nitrate, and metal and nonmetal salts of the foregoing fuels. 6. The gas generant composition of claim 4 wherein: said inorganic oxidizer is selected from the group consisting of phase stabilized ammonium nitrate and strontium nitrate. 7. The gas generant composition of claim 4 wherein: said inorganic oxidizer is selected from the group consisting of alkali, alkaline earth, and transitional metal nitrates, nitrites, chlorates, chlorites, perchlorates, oxides, and mixtures thereof.
