PURPOSE:To filtrate combustion gas certainly by forming a gas filling filter from an upper filter arranged beside an orifice and a gas filtrating filter arranged in its lower part through a partitioning plate. CONSTITUTION:A partitioning plate 89 has such an effect that the combustion gas, which has flowed into a gas fill chamber 51 upon passing a combustion chamber filter 49, flows into an upper filter 53, changes the stream of this combustion gas, and leads to a gas filtrating filter 55. The upper filter 53 turns the combustion gas into turbulence by allowing a high speed combustion gas jetted from an orifice 82 to run against the filter 53 and has an effect to attach the residues of combustion gas to a wire meshing. The filter 55 has functions to cool the combustion gas to a degree at which the air bag will not burn off, remove the residues from combustion contained in the combustion gas, and supply only harmless nitrogen gas to the air bag. Thereafter it flows into the air bag from a gas outflow hole 57. |
