GAS GENERATOR FOR INFLATING A SAFTY BAG

TITLE OF THE INVENTION GAS GENERATOR FOR INFLATING A SAFETY BAG A gas generator for inflating a safety bag for the protection of persons in a vehicle, is equipped with a combustion chamber that is divided into a smaller section and into a larger section by a sheet metal insert. The sheet metal insert also divides the fuel into two portions, whereby a smaller fuel portion is located closer to the ignition openings of an ignition device while the larger fuel portion is located further away from the ignition device. The divider or insert provides a passage or gas flow openings which are so located that the combustion gas generated in the smaller section must flow entirely through the smaller section before it enters into the larger section. Thus, the smaller fuel portion is combusted substantially first and the larger fuel portion is combusted thereafter to provide an inflation characteristic for the safety bag such that the bag is initially filled slower and then rapidly.

Two-stage automotive gas bag inflator using igniter material to delay second stage ignition

ABSTRACT OF THE DISCLOSURE A dual-stage gas bag inflator, operable initially, when activated, to cause the gas bag to deploy slowly and then, after a delay, to deploy rapidly, includes a housing having first and second compartments of different size separated by a bulkhead. The first compartment is the smaller since it is to produce a smaller amount of gas to cause the initial slow deployment of the gas bag. A gas generant charge is ignited in the first compartment, and after some delay, a gas generant charge in the second compartment is ignited. The delay is produced by an initiator including a squib, igniter material in each of the first and second compartments, and a fuse cord which is ignited by the squib. The fuse cord passes through the bulkhead and ignites all igniter materials in both inflator compartments simultaneously. The igniter material in the second compartment is so characterized that it burns slower than the igniter material in the first compartment. When ignited, the igniter material in the first compartment burns outwardly rapidly while that in the second compartment burns outwardly relatively slower. As a result, the gas generant in the first compartment is ignited before the gas generant in the second compartment. The burn rate of the igniter material in the second compartment may be made slower than that in the first compartment by using igniter materials of different chemical composition or by increasing the size of the igniter material, giving it a greater burn area, thus causing it to by consumed slower.

PYROTECHNIC ADAPTIVE GAS GENERATOR WITH TUBULAR CHAMBERS FOR PROTECTIVE CUSHION

Le générateur (1) comporte un boîtier (2) cylindrique qui présente une paroi latérale (3) fermée à ses deux extrémités. Une plaque (6) transversale divise ledit boîtier (2) en une partie amont (9) et une partie aval (10). La partie amont (9) contient un tube (16) qui sépare de façon étanche deux chambres de combustion (17, 18) munies chacune d'un chargement pyrotechnique (19, 20). Un dispositif électrique d'allumage (5) est constitué par un initiateur à double tête (21, 22) ne comportant qu'une seule alimentation électrique. Les deux têtes (21, 22) peuvent être incorporées à un pont de commutation comportant quatre interrupteurs combinés à un circuit à diodes. Ainsi, il est possible, soit de n'initier qu'une seule tête (21, 22) au choix, soit d'initier les deux selon un décalage programmé dans le temps. Le générateur selon l'invention permet de constituer un générateur progressif destiné à gonfler un coussin de protection. The generator (1) comprises a cylindrical housing (2) which has a side wall (3) closed at both ends. A transverse plate (6) divides said housing (2) into an upstream part (9) and a downstream part (10). The upstream part (9) contains a tube (16) which sealingly separates two combustion chambers (17, 18) each provided with a pyrotechnic charge (19, 20). An electric ignition device (5) consists of a double-headed initiator (21, 22) comprising only one electric power supply. The two heads (21, 22) can be incorporated in a switching bridge comprising four switches combined with a diode circuit. Thus, it is possible either to initiate only one head (21, 22) as desired, or to initiate both according to a programmed offset in time. The generator according to the invention makes it possible to constitute a progressive generator intended to inflate a protective cushion.

La presente invención se refiere a un generador de gas que comprende: un sólo alojamiento alargado perforado, extruído por percusión, que tiene un primer y un segundo extremos; una base de tapa de extremo que cierra el primer extremo del alojamiento; una tapa de extremo que cierra el segundo extremo del alojamiento; un mamparo perforado colocado en un sitio intermedio dentro del alojamiento, formando el mamparo primera y segunda cámara alargada dentro del alojamiento y teniendo formada en el mismo una válvula de bola que incluye una cámara de válvula de bola y primera y segunda aberturas que conectan la cámara de válvula de bola con la primera y segunda cámaras alrgadas, respectivamente, con la entrada a la segunda cámara denotando una primera posición y la entrada a la primera cámara denotando una segunda posición, alojando la cámara de válvula de bola una bola en la misma, que es movible, mediante lo cual la bola es capaz de operar para moverse entre la primera y segunda posiciones para restringir el flujo de gas a través del mamparo; con lo cual en un segundo momento, la primer cámara queda a presión, forzando la bola de la válvula de bola hacia la primera posición, suprimiendo el flujo de gas en la segunda cámara y aislando de esta manera la primera cámara de la segunda cámara; por lo cual en un tercer momento, una caída de presión en la primera cámara afloja el acoplamiento de la bola de la válvula de bola en la cámara de válvula de bola, desde la primera posición, y la presión incrementada en la segunda cámara forza la bola hacia la segunda posición y aisla la segunda cámara de la primera cámara; primera y segunda cargas generadoras de gas, alargadas, de un material pirotécnico sólido, contenidas en la primera y segunda cámaras alargadas, respectivamente; primero y segundo tubos de encendido pereforados, alargados, provistos en relación de funcionamiento con la primera y segunda cargas generadoras de gas alargadas, respectivamente, teniendo cada uno de los ...

Autoignition compositions

A gas generator 10 includes an autoignition composition that contains an alkali metal chlorate such as potassium chlorate as an oxidizer, a carboxylic acid such as DL-tartaric acid as a fuel, and a desiccant in operable communication therewith. Gas generating systems 180 such as vehicle occupant protection systems 180 , containing the gas generator 10 , are also provided.

Gas generator for air bag system of vehicle, has pipe with ignition region whose middle diameter is larger than middle diameter of transmission region, where area of holes in ignition region is less than area of holes in transmission region

The generator has a flame transmission pipe (30) arranged in an axial direction of a tubular shaped housing within a combustion chamber and equipped with a set of communications holes The pipe has a ignition region (31) and a flames transmission region (32), and the middle inner diameter of the region (31) is larger than the middle inner diameter of the region (32). The overall openings surface area of the holes in the region (31) is less than the overall openings surface area of the holes in the region (32).
