摘要： PROBLEM TO BE SOLVED: To dispense with a filter for filtering of an inflator to reduce the size and weight of the inflator and improve the cooling performance of gas temperature during work.SOLUTION: A gas generated at a combustion chamber 42 enters a cooling space 44, where the same hits a bottom wall 26D of an upper case 26 (inflator case 12) and flows into a gas channel 48, and then jets out of a gas nozzle 26C. Either of the upper case 26 and a lower case 28, for example, the upper case 26 having the bottom wall 26D facing the cooling space 44 is provided with an integral fitting flange 26F (flange) for fitting to a given part. Hence heat is released efficiently through the integral fitting flange 26F (flange) toward the given part.

摘要： PURPOSE:To provide a gas generator for an air bag which is easy for fitting a mechanical sensor, and small in size and light in weight. CONSTITUTION:A gas generator for an air bag comprises a housing, a gas generating means inside the housing, and an ignition means of the gas generating means; and it is purposed to protect an occupant from shock by introducing the gas generated by the shock by means of the gas generating means into an air bag. The ignition means is made up of a single detonator 11 that is detonated by sticking a mechanical sensor 4 by means of a sticking pin 8, a transfer charge that is ignited by the firing of the detonator 11, and a transfer charge housing chamber 14 for housing the transfer charge; and that is housed inside the central cylinder 3b arranged in the central part inside the housing.

摘要： PURPOSE:To restrict height of an inflator to low, and while obtain a large distance between an ignition bin and firing agent by arranging inflammation agent in a side of the firing agent to be arranged in the ignition direction of the ignition bin, and arranging gas generating agent in the surroundings of the inflammation agent and the firing agent. CONSTITUTION:In a mechanical ignition type inflator D, inflammation agent 13 is arranged in a side of firing agent 12 to be arranged in the ignition direction of an ignition bin 17b, and gas generating agent 14 is arranged in the surroundings of the inflammation agent 13 and the firing agent 12. Height of the inflator D can be therefore restricted to a height specified with an arrangement space of a starting device 17 and an arrangement space of the firing agent 12 and the inflammation agent 13, while a distance between the ignition bin 17b and the firing agent 12 can be made large within a height to be allowed by the inflator D. Consequently, collision energy of the ignition bin 17b against the firing agent 12 can be made large.

摘要： PROBLEM TO BE SOLVED: To provide an inflator which can be reduced in size and weight by dispensing with filters for cooling and filtering and ensures that a gas is quickly jet out of a gas nozzle during work.SOLUTION: A gas generated at a combustion chamber 42 enters a cooling space 44, where the same hits a bottom wall 26D of an upper case 26 (inflator case 12) and flows into a gas channel 48, and then jets out of a gas nozzle 26C. At this time, the high-temperature gas and the inflator case 12 exchange heat to cool the gas. Mist contained in the gas meets flow resistance when passing through the cooling space 44 and the gas channel 48, thereby deposits on the bottom wall 26D of the upper case 26 (inflator case 12), and is eliminated effectively. When an internal pressure of an outer cylindrical member 18 rises because of the generated gas, a deformation suppressing means 24 prevents the other end 18B of the outer cylindrical member 18 from deforming outwardly, thus suppressing the contraction of the gas channel 48.
摘要翻译：要解决的问题：提供一种可以通过分配用于冷却和过滤的过滤器来减小尺寸和重量的充气机，并确保在工作期间气体被快速地从气体喷嘴喷射出来。解决方案：在燃烧室42产生的气体进入冷却空间44，同时撞击上壳体26（充气机壳体12）的底壁26D并流入气体通道48，然后喷出气体喷嘴26C。此时，高温气体和充气器壳体12交换热量以冷却气体。气体中所含的雾气通过冷却空间44和气体通道48时会遇到流动阻力，从而沉积在上壳体26（充气机壳体12）的底壁26D上，并被有效地消除。当外圆柱形构件18的内部压力由于产生的气体而上升时，变形抑制装置24防止外圆柱形构件18的另一端18B向外变形，从而抑制气体通道48的收缩。版权所有（C）2012，JPO＆INPIT

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.
