Abstract
A gas generator for automobile gas bags and the like includes a grain wherein a plurality of wafers of combustible gas generating material is arranged in a side by side array and a plurality of meshed cushion members is disposed in alternating relation between the wafers and compressed between the wafers in order to provide improved burn surface neutrality for more uniform inflator gas flow and better utilization of the gas generant, increased retention of solid residue in the combustion chamber for reduced plugging of the gas filters and cleaner inflation gas, a higher volumetric loading fraction so that the size and weight of the inflator may be reduced, and structural suspension of each individual wafer between the adjacent compressed cushion members to reduce breakage and damage of the wafers during the many years the inflator may remain in an automobile.
