초록 ▼

Gas generator for an inflatable impact cushion for protecting an occupant of a motor-vehicle from injury, has a housing, in which is formed a storage chamber for liquified gas. The storage chamber is separated by a partition wall from a combustion chamber also formed in the housing. An ignition device is positioned in a precombustion chamber, and has an ignition charge to generate combustion gases during ignition. In the precombustion chamber there is guided, in a displaceable manner, a piston which, because of the combustion gases of the ignition charge, moves into and through the combustion chamber in a direction of the partition wall, in order to penetrate the partition wall. When the partition wall is penetrated there is a connection between the storage chamber and the combustion chamber by way of a liquified gas channel system so that liquid gas can flow into the combustion chamber. At the same time a connection is created between the precombustion chamber and the (main) combustion chamber by way of ignition channels formed in the piston. Hot combustion gases of the ignition charge ignite the liquified gas. The rising internal pressure in the combustion chamber causes displacement of the longitudinally displaceably guided partition wall, which moves together with the piston and thereby continuously forces liquid gas from the storage chamber into the combustion chamber. The combustion gases emerge, through outlet openings in the housing.

대표청구항 ▼

A gas generator for an inflatable impact cushion of a motor vehicle which comprises: a housing, in which a combustion chamber is formed; at least one outlet opening in a wall of the housing for emergence of combustion gases forming in the combustion chamber; a storage chamber for storing liquified gas within said housing, the storage chamber being separated from the combustion chamber by a partition wall; an ignition device, arranged adjacent to said combustion chamber, with an ignition charge for generating combustion gases for igniting the liquified gas; and a longitudinally displaceably guided piston which, when the ignition charge is ignited, is displaced in a direction of the partition wall and penetrates the partition wall due to the gas pressure formed, as a result of the combustion of the ignition charge; first channel means located in a region of a rear end of the piston in the direction of movement for allowing the combustion gases of the ignition charge to arrive in the combustion chamber, and second channel means in a region of a front end of the piston for allowing liquified gas from the storage chamber to arrive in the combustion chamber and to burn therein.
