| 41 | Pyrotechnic stored gas inflator | US10943458 | 2004-09-17 | US20050110253A1 | 2005-05-26 | Paresh Khandhadia; Jeffery Blackburn |
| An inflator (10) for use in an inflatable vehicle occupant protection system. The inflator (10) includes a pressure vessel (12) having an opening (60) formed therein. A quantity of relatively unreactive pressurized gas is stored in the pressure vessel (12). A quantity of a gas generant composition (14) is positioned in an interior of the pressure vessel (12) and in fluid communication with the pressurized gas. An igniter (18) is positioned proximate the gas generant (14) for initiating combustion of the gas generant. A rupturable, fluid-tight seal (30) is positioned to seal the opening (60) in the pressure vessel (12) for maintaining the pressurized gas within the pressure vessel (12) prior to activation of the igniter (18). Activation of the igniter (18) results in combustion of the gas generant (14). Pressure from the combustion gases, in combination with the pressure of the gases stored under pressure in vessel (12), cause the burst disk (30) to rupture, providing an inflation gas to an associated vehicle airbag, for example. Also provided is a method for manufacturing an inflator for use in an inflatable vehicle occupant protection system. | ||||||

| The present invention relates to a hybrid gas generator (1), used for motor vehicle safety to inflate an airbag, comprising a body (2) containing an ignition device (16) and a reservoir (3) connected to the body and containing a pressurized gas (31), together with initially closed-off discharge orifices (10). The body possesses a first pyrotechnic charge (14) capable of generating a quantity of gas which, coupled to the volume of gas (31) contained in the reservoir, allows the airbag to be inflated in a time period of less than 50 milliseconds, and a second pyrotechnic charge (13) capable of generating, after combustion of the first pyrotechnic charge, a quantity of gas sufficient to keep the airbag inflated for a time period of several seconds. | ||||||

| 45 | Hybrid gas generator provided with an initiator with shaped explosive charge | US09490146 | 2000-01-24 | US06338500B1 | 2002-01-15 | Christian Perotto |
| The invention relates to a hybrid gas generator intended for motor vehicle safety. The generator (1) includes a container (2) containing a cold gas (10) under pressure and having an open end in which a compartment (2), which is located outside the container (2), is fixed. This compartment (3) is provided with gas discharge orifices (6) and has a front wall (8) in which there is an opening closed by a diaphragm (9) which makes it possible to separate the inside of the container (2) from the inside of the compartment (3), in a leaktight fashion. The latter contains an initiator (12) with shaped explosive charge and a pyrotechnic charge (13), the initiator (12) being capable of destroying the diaphragm (9) from a distance and of initiating the pyrotechnic charge (13). This generator (1) makes it possible to initiate deployment of the airbag using cold gas (10) as soon as it starts to operate. | ||||||

| An improved hybrid airbag inflator comprises a container for storing a compressed gas having a rupturable wall defining an exit opening. A pyrotechnic gas generator has an output directed into the container for adding heat and mass flow to the compressed gas in the container. A single initiator ruptures the rupturable wall and initiates the gas generator, preferably via a pyrotechnic delay train which initiates combustion of the gas generator after a predetermined delay, to provide for delayed onset of the high pressure gas generator input. The initiator is preferably an electric detonator that produces a self forging fragment to rupture the rupturable wall and initiate the pyrotechnic delay. The pyrotechnic generator may also have a second output directed into a manifold leading from the container to the airbag and entering the manifold downstream from the inlet nozzles that restrict the flow of compressed gas into the manifold. | ||||||

| An initiator suitable for use with airbag passive restraint systems and which does not use pyrotechnic materials is disclosed. The initiator provides an electrically actuated igniter which ignites an adjacently stored non-pyrotechnic fluid combustible material which may comprise a mixture of a fluid fuel and a fluid oxidizer, a fluid monopropellant or a fluid exothermically decomposable material. A sub-assembly of the non-pyrotechnic initiator with a fuel containment chamber and inflators which use the non-pyrotechnic initiator are also disclosed. | ||||||

| An airbag inflator comprises a housing having an interior and gas outlet ports communicating with the interior and open to outside the housing. First and second divider walls separate at least two gas chambers from the interior. A pressurized combustible gaseous mixture is stored in each gas chamber. An initiator is disposed within each gas chamber and actuatable to ignite the pressurized combustible gaseous mixture. | ||||||

| A hybrid gas generator for vehicle safety, systems, in particular airbag inflating and seat belt tensioning systems or pyrotechnical isolating switches for disconnecting the vehicle electrical system from the vehicle battery in the event of an impact accident, is described, whereby a moving piston is provided to destroy the bursting diaphragm which closes off the compressed gas container. This piston is moved towards the bursting diaphragm by igniting an ignition system whereby according to this invention the piston has a flange-shaped projection which is located against a shoulder on the internal surface of a sleeve facing the piston and is designed such that when the ignition system is ignited the flange-shaped projection shears off. Advantageously, the operating pressure in the combustion chamber of the hybrid gas generator according to this invention can thus be determined by the area of the shearing surface on the flange-shaped projection. | ||||||

| An apparatus for use in inflating an air bag comprises a container (15) containing a supply of inflation fluid. The container has a first outer surface (19) and an inner surface (26) which is threaded and defines a threaded opening extending into the container from the first outer surface. A plug (40) has an outer periphery (45) which is threaded. The plug is screwed into the threaded opening in the container. The outer periphery of the plug includes a second outer surface (51) adjacent the first outer surface of the container. The outer periphery of the plug and the inner surface of the container that defines the threaded opening comprise an interface (11) between the plug and the container. The interface extends to the periphery of the container between the first and second outer surfaces. A ring (30) overlies both the interface and portions of the first and second outer surfaces. The ring is secured to the first and second outer surfaces to block leakage of inflation fluid from the container through the interface. | ||||||
| 51 | Generator of cool working gases | US3640083D | 1970-03-27 | US3640083A | 1972-02-08 | GALBRAITH LYLE D; THORN WILLIAM F |
| Hot pressure gases are generated by burning a solid fuel grain. A portion of the gases are used to pressure feed a liquid from its storage chamber into a mixing zone. The remainder of the hot gases are directed into the mixing zone for mixing with the liquid. The hot gases provide the heat of vaporization for, and cause the vaporization of, the liquid. The gas generator comprises a one-piece housing of composite welded construction, defining liquid storage, breech and mixing chambers. A control cartridge containing burst discs, flow control orifices and seals is inserted into the housing through the outlet passageway. A solid fuel cartridge is inserted into the breech through an opening at the opposite end of the housing.

A shotgun shell is encased in a barrel member and locked in place with a screw-on housing. When the shell is fired, the gases expelled by the shell push a knife blade forward into a gas container positioned within the main housing. The moving knife blade ruptures the gas container and the gas therein escapes and the powder gas from the shotgun shell ignites the gas escaping from the container creating various visual effects, such as a fireball. | ||||||
