12. In an inflatable vehicular safety restraint system including an inflator having a combustion chamber wherein a gas generant material is burned to generate a gas for use in inflation of an inflatable vehicle occupant restraint, the generated gas containing particulate of the gas generating material and byproducts thereof, the inflator also including at least one exit port for dispensing an inflation gas comprising at least a portion of the generated gas into the inflatable vehicle occupant restraint, the improvement comprising:
the vehicular safety restraint system further including treatment means comprising at least one layer of expanded metal, said layer of expanded metal being contacted by at least a portion of the particulate-containing generated gas and effecting reduction in the particulate content of the contacting gas prior to passage into the inflatable vehicle occupant restraint of inflation gas comprising the particulate content reduced portion of the generated gas. - View Dependent Claims (13, 14, 15, 16, 17)

18. In a vehicular safety restraint system including an inflator forming a housing having a combustion chamber wherein a gas generant material is burned to produce a hot gas containing particulate of the gas generating material and byproducts thereof, the inflator also including at least one exit port for dispensing inflation gas into a vehicle occupant restraint, the improvement comprising:
the inflator further including filter means comprising at least one layer of expanded metal housed within the combustion chamber, said layer of expanded metal being contacted by the particulate-containing hot gas and effecting reduction in the particulate content of the contacting gas. - View Dependent Claims (19)
