Abstract
A new filtration system for gas generators, especially side impact airbag inflators for use in automobiles, has a sheet of expanded metal formed into a tube, cylinder or other geometric form and a bed of expanded metal chips. The interior of the geometric form is filled with chips of expanded metal and this configuration has been found extremely effective in cooling and filtering the gases produced during the combustion of a gas generant. The filtration system disposed between the gas generant bed and the gas exit apertures of the inflator housing. The weight of the filtration system should be at least four times the weight of the gas generant placed in the inflator housing.
