PURPOSE: To obtain a light-weight, low-cost gas generator without the use of a pressure-resistant container by winding a gas generating agent layer consisting of a high tensile single fibrous material and a gas generating agent around an ignition device and sealing both ends using a sealing agent. CONSTITUTION: A gas generating agent fibrous material obtained by applying a gas-generating agent paste uniformly to the surface of a high tensile, highly flexible yarn and drying the paste, is wound helically around the outer periphery of a cylindrical fire tube 1 in layers to form a gas generating agent layer 2. Further, a coolant fibrous material obtained by applying a coolant to the outer surface of the same yarn and drying the coolant, and a filter fibrous material are wound likewise around the outer periphery of the gas generating agent layer 2 sequentially in layers to provide a coolant layer 4, a filter layer 6 and a reinforcing layer 10. Further, a sealing layer 9 is formed on both end surfaces of the gas generating agent layer 2, coolant layer 4, filter layer 6 and reinforcing layer 10, using water glass. The fire tube 1 is previously filled with an ignition powder 5, and a squib 3 which is activated by an electric signal from a lead wire 8 is installed on the end part of the fire tube. The gas generator thus obtained is stored in a moisture-proof case 7. |
