摘要： The present invention provides a gas generator in which ignition and combustion performance of a gas generating agent and operation performance are enhanced. An inner cylindrical member 4 is disposed in a cylindrical housing 3, an annular first combustion chamber 5a is provided radially in the outside of the inner cylindrical member 4, and, in the combustion chamber 5a, a ratio (D/L) of its radial average distance (D) to its axial average length (L) is adjusted to be in the range of 0.2 to 2.0. The invention provides a gas generator for an air bag capable of reducing a size of the gas generator and easily and reliably adjusting a capacity of a combustion chamber which accommodates the gas generating agent, and also provides a retainer for such a gas generator. The invention provides a retainer which changes a flow of a gas ejected from a through-hole of an inner cylindrical member provided in the housing and has a cylindrical portion for collecting fluid and semifluid combustion products included in the gas, and provides a gas generator for an air bag using such a retainer. The invention provides a gas generator for an air bag comprising, in a housing having a gas discharging port, a inner cylindrical member having a cylindrical peripheral wall, and two combustion chambers defined by the inner cylindrical member, in which a gas generating agent to be ignited for generating a working gas is charged in the respective combustion chambers, and working gases generated in the respective combustion chambers pass through different flow-paths and reach the gas discharging port. The present invention further provides a gas generator for an air bag in which, in a housing having a gas discharging port, an inner cylindrical member having a cylindrical peripheral wall is disposed, two combustion chambers are defined by the inner cylindrical member, a gas generating agent which is burnt to generate a working gas is charged in each of the combustion chambers, and working gases generated in the respective combustion chambers pass through different flow-paths to reach a coolant means.

摘要： The present invention provides a gas generator for an air bag whose reliability is improved.
Since a grounding pin 191 is set to minus, even when plus current flows from a first igniter 112a to a second igniter 112b, the current flows in only the minus grounding pin 191 so that there is no possibility such that the second igniter 112b may be activated erroneously by the activation of the first igniter 112a.
摘要翻译：本发明提供了一种可靠性提高的气囊气体发生器。由于接地引脚191被设定为负，即使当正电流从第一点火器112a流到第二点火器112b时，电流仅流过负接地引脚191，使得不存在第二点火器112b可能为通过第一点火器112a的激活而错误地激活。

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).
