摘要： A simple-structure, air bag-use gas generator capable of positively protecting occupants by being operated with a minimum impact to occupants in an initial stage of operation and then quickly increasing a gas pressure. An air bag-use gas generator comprising an inner tube member disposed in a housing to partition an ignition means-housing chamber from a combustion chamber, and a plurality of transfer charge holes formed in the peripheral surface of the inner tube member to allow communication between the two chambers, the plurality of transfer charge holes being formed so that their distances from the end of the inner tube member are less than 30% of the axial length of the inner tube member. A gas generator capable of using even a gas generating agent inferior in ignitability and delivering a satisfactory operating performance in an initial stage of operation when such a gas generating agent is used. A air bag-use gas generator comprising an inner tube member disposed in a housing to partition an ignition means-housing chamber from a combustion chamber, a plurality of communication portions formed in the peripheral surface of the inner tube member being adjusted so that central angles formed by adjoining communication portions are up to 60°.

摘要： A gas generator for air bags which is increased in safety and reliability. Even when a gas generating agent (9a) in a first combustion chamber (5a) is burnt, burning of a gas generating agent (9b) is prevented by the action of a metal thin plate (11) closing a communication hole (10) leading to a second combustion chamber (5b). An igniter (1112) has fitted thereon a cup (1190) having a hole (1191), and the flames produced at the time of firing form a narrow, straight stream to a transfer charge (1116). Thus, the transfer charge (1116) completely burns, reliably producing sufficient flames for complete combustion of a gas generating agent (1109). An ignition means receiving chamber (2008) contains the igniter and the transfer charge, and the filling density of the transfer charge (2016a) in a transfer charge receiving chamber (2015a) is 0.1 - 5 g/cm3. A communication hole (3010) between the first and second combustion chambers (3005a, 3005b) is closed by a seal tape (3011) composed of two layers with an adhesive layer interposed therebetween. After actuation, the seal tape (3011) does not burst by a rise in the internal pressure in the first combustion chamber (3005a) but easily comes off by a rise in the internal pressure in the second combustion chamber (3005b).

摘要： The present invention provides a ruptuable plate in which broken pieces are hardly produced. In an inflator for inflating an article to be infalted with a pressurized medium, a rupturable plate for an inflator blocking and closing between a portion which is charged with a pressurized medium and maintained at high pressure and a portion which is not charged with a pressurized medium and maintained at normal pressure is provided. The rupturable plate is mounted to the inflator by fixing a peripheral edge portion thereof to the inflator, and is further provided with one or two or more selected from the followings: (a) a ratio (diameter/thickness) of a thickness and a diameter is 14 to 50, (b) a tensile strength is 880 to 1100 N/mm , and (c) an elongation is 25% or more. And in the rupturable plate, the whole remaining portion excluding the fixed peripheral edge portion falls off without breaking when the rupturable plate receives a pressure of the igniter.

摘要： The present invention provides an inflator capable of prolonging the duration of inflation of an air bag.
Since an inflator housing 12 of an inflator 10 for a curtain air bag is charged with a pressurized medium comprising a mixed gas of He and Ar (He: Ar = 3: 7 to 7: 3) , the sound velocity of the pressurized medium is smaller than that of a pressurized medium comprising He only, and the viscosity of the former is higher than that of the latter, so that the duration of the inflation of an air bag can be prolonged.

摘要： The invention provided a gas generator for an air bag having any of the following members. A deflecting member is provided to suppress discharge of a combustion product generated by a combustion of gas generating means, and is formed as a tube portion to be capable of shielding a gas discharge port formed at least on a circumferential wall of a housing from the inside of the housing. A coolant/filter means supporting member can position a coolant/filter means, prevent a short pass of an operating gas, and functions as a buffer member between the coolant/filter and the housing, and/or prevent a heat from being transferred to a diffuser shell, and comprises an annular portion arranged to face an end surface of the housing and a wall portion contacting with an inner periphery of the coolant/filter means. Further, in order to make it possible to securely support and fix the coolant means and prevent the short pass of the operating gas, an outer peripheral edge of an end portion thereof is adhered and/or supported to a bent portion or a step portion formed in an inner surface of an upper end surface and/or an inner surface of a lower end portion in the housing. The coolant/filter means is formed in a cylindrical shape obtained by laminating a wire mesh. The housing for the gas generator securely fixes an igniter included in an ignition means, is preferably used at a time of manufacturing a gas generator having a restricted overall height, and has an opening portion for inserting and fixing the igniter or an igniter supporting member. The opening portion is provided with a connecting portion for fixing the inserted igniter or igniter supporting member, and the connecting portion is provided in inner side of the housing rather than the end surface having the opening portion.
