A gas generating inflator assembly for a vehicle safety restraint system including an inflator housing having two walls, an inner wall and an outer wall. The inner and outer walls form a combustion chamber therebetween. A filter pack is disposed within the combustion chamber along an inner diameter of the outer wall. Gas generant is also disposed within the combustion chamber. An internal structure is disposed within the combustion chamber for diffusing the ignitor blast and retaining slag produced by the ignited gas generant. The internal structure is spaced from the filter pack and the inner wall such that a portion of the gas generant is located between the internal structure and the inner wall and another portion of the gas generant is located between the internal structure and the filtration pack. The internal structure can be a ring of solid material, an expanded metal material or screen, a star-shaped configuration having a plurality of portions contacting an inner diameter of the filter pack, or a solid metal structure which may include an internal porous structure screen of wire mesh or expanded metal attached thereto.
