摘要： PROBLEM TO BE SOLVED: To provide an inflator containing pressurized gas, having less exhausted combustion residues. SOLUTION: The high temperature combustion residues in combustion gas of a gas generating agent 36 are gathered in the inflator 10 and less exhausted to the outside as a result of the composition of the gas generating agent 36, a temperature difference between the combustion gas and the pressurized gas isolated from each other by a first rupture disc 40 and the collision of the combustion gas with a wall face 22a.

摘要： PROBLEM TO BE SOLVED: To prevent malfunction from being generated. SOLUTION: When combustion is generated in the first gas generation chamber 130, combustion gas flowing out from the first communication hole 136 flows along the direction toward an inner wall in an inflator housing 102, and is prevented from flowing along the direction toward the second gas generation chamber 140. The second gas generation chamber 140 is prevented thereby from generating the malfunction by heat energy of the combustion gas.

摘要： PROBLEM TO BE SOLVED: To provide a gas generator for an air bag, provided with simple construction ensuring protection of a crew in such a manner that it is operated without giving the least impact to the crew at the initial stage and then a gas pressure is rapidly increased. SOLUTION: This gas generator for an air bag comprises a housing having a gas exhaust port, storing single ignition means operated with impact and a gas generating agent to be ignited an burned by the igniting means to generate a combustion gas. The housing has a combustion chamber where the gas generating agent is burned and the combustion chamber has a space portion held where no gas generating agent of preset capacity exists, so that the combustion capacity of the gas generating agent is expanded to the space portion during ignition and burning of the gas generating agent.

摘要： PROBLEM TO BE SOLVED: To provide a gas generator for an air bag with excellent ignition combustibility of gas generation agent. SOLUTION: When high temperature gas by an operation of a first igniter 21 flows from a first communication hole 34 to a combustion chamber 40 in this gas generator, the gas generation agent 43 closer to the first communication hole 34 burns first and combustion gas is easy to flow toward a larger communication hole 85. As a result, ignition combustibility of the gas generation agent 43 distant from the first communication hole 34 can be improved. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a gas generator for an air bag having a filter with a high cooling effect. SOLUTION: The gas generator has a housing having a gas exhaust port, an ignition means chamber having an ignition means operated by an impact, and a combustion chamber storing a gas generating agent for generating combustion gas by ignition and combustion. A cylindrical filter 65 is disposed between the combustion chamber and the gas exhaust port, and the combustion gas is discharged from the gas exhaust port through the filter. An inner cylindrical shielding plate 66 is arranged inside the cylindrical filter 65, the lower end opening rim of the inner cylindrical shielding plate contacts with a housing bottom surface, the upper end opening rim is arranged so as to provide a space between it and the housing ceiling surface, and a section having high permeability is disposed between the inner surface of the cylindrical filter and the inner cylindrical shielding plate 66. Heat resistance is required in the inner cylindrical shielding plate, so that it is made of metal such as stainless steel. A gas flow is provided by operations of the inner cylindrical shielding plate 66 for grappling the cylindrical filter 65 for cooling the combustion gas from both sides, an outer cylindrical shielding plate 67, a first clearance 71, and a second clearance 72. The cooling effect of the combustion gas is improved. COPYRIGHT: (C)2004,JPO&NCIPI
