1. A gas generating composition, which is installed in a vehicle occupant restraint system and generates gas by a combustion reaction when the vehicle occupant restraint system is actuated, wherein the gas generating composition essentially consists of:ammonium nitrate as an oxidant; and microcrystalline activated carbon as an reductant, wherein the microcrystalline activated carbon has a specific surface area of 700 to 1600 m2/g, wherein the weight ratio of the ammonium nitrate to the microcrystalline activated carbon is between 95:5 and 99:1, wherein the gas generating composition has a predetermined size and shape, the shape being one of a cylinder, a tube, a lobed tube having a plurality of through holes, and a polygonal prism having a plurality of through holes.
