摘要： PURPOSE:To prevent production of a burr, eliminate a remaining protrusion so as to reduce the size and weight by connecting a diffuser shell to a closure shell by means of electron beam welding. CONSTITUTION:A housing 1 is composed of a diffuser shell 2 and a closure shell 3, and the diffuser shell 2 is composed of a circular part 2a, central cylinder part 2b and inner cylinder part 2c. The central cylinder part 2b is provided with a caulking part 4 for fixing an ignition means and the inner cylinder part 2c accommodates a combustion means. The closure shell 3 is composed of an annular part 3a having a center hole 7 and a peripheral wall part 3b, and the peripheral wall part 3b is provided with a flange part 3c extending in the radial direction. A welded part 13 is formed in an outer peripheral part of the central cylinder part 2b and an outer peripheral edge part of the center hole 7; a welded part 14, at a tip part of the inner cylinder part 2c and in a region of the annular part 3a; and a welded part 15, at a peripheral edge part of the circular part 2a and a tip part of the peripheral wall part 3b. Since the welded parts 13, 14, 15 are electron beam welded, a remaining protrusion due to friction welding is not generated so as to miniaturize.

摘要： PURPOSE:To make mounting of a detonator safe and easy by forming a space between a sensor housing chamber and an ignitor chamber of a gas generator so that the space abuts on bothe the chamber, and providing a means for fixing a donator-piece for holding the detonator in the space. CONSTITUTION:A gas generator is composed of a diffuser shell 1 and a closure shell 3, and a space 2 is formed by the closure shell 3 and the diffuser shell 1. The inside of the space 2 is confined by an inner tube 1d of the diffuser shell 1 in the circumferential direction to form a sensor housing chamber 14 in the inner tube part 1d, and an ignitor chamber 17 is formed in the circular part 1b of the diffuser shell 1, namely in the upper part of the sensor housing chamber 14. A space formed between the sensor housing chamber 14 and the ignitor chamber 17 is used as a detonator storage chamber 20 in order to fix a detonator-piece 21 by a screw means 22. The detonator-piece 21 has a hole 21b, in which a detonator 11 is loaded. Besides, a projected part 21a is provided in the middle of the detonator-piece 21 so as to penetrate into the transfer charge chamber 17.

摘要： PURPOSE:To reduce density with which combustion residue within gas is adhered onto a cut-out section, thereby enhance cooling effect by forming a circular gas cooling member which is interposed to a cooling member chamber provided for the outside of a gasifying agent chamber in the radial direction, into a shape in such a way that an inner lower portion of a cros section in the radial direction is cut out. CONSTITUTION:The bottom section of a gas generator container 13 is broken by gas or pressure built up by gasifying agent 21, after that, gas goes to the radial direction so as to go into a cooling member 14 in a cooling member chamber 10. In this case, the lower inner diameter side of the cooling member 14 is formed with a cut-out 15, to the surface of which residue is adhered. The surface area of the cooling member 14 is widened by the aforesaid cut-out 15, the amount of adhesion per unit area is thereby lessened so that gas flows smoothly. In addition, the cut-out allows gas to flow into the center section of the thickness of the cooling member 14 with no restriction while streaming in the shaft vertical direction, thereby enhancing cooling effect.

摘要： PROBLEM TO BE SOLVED: To provide a gas generator for an air bag with a simple structure. SOLUTION: An inner cylindrical member 504 is arranged inside a housing. A second combustion chamber 560 filled with a second gas generator 522 is provided inside the inner cylindrical member 504, and a first combustion chamber 550 filled with a first gas generator is provided outside the inner cylindrical member 504. A notch 512 serving as an opening part communicating the first combustion chamber 550 with the second combustion chamber 560 is formed on a peripheral wall of the inner cylindrical member 504. Due to combustion of the second gas generator 522, the notch 512 is opened, so as to communicate the first combustion chamber 550 with the second combustion chamber 560. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an inflater capable of maintaining the pressurized gas flow rate to be substantially constant when the inflater is operated. SOLUTION: Broken pieces generated by the rupture of a first rupture disk 22 are captured around the top point 20b of the inner surface of a filter 20, and the remaining inner surface is not brought into contact with the broken pieces. Thus, the gas flow is not impaired by the broken pieces, and the pressurized gas flow rate can be maintained to be substantially constant. COPYRIGHT: (C)2004,JPO
