  • Patent number: 6254128
    Abstract: The invention relates to a gas generator for an air bag (11) including a cartridge (3) containing a gas-generating charge of solid material (5) and a storage reservoir (9) containing a storage gas (10). To trigger gas production the charge of solid material (5) is ignited. The resulting gas pressure tears off the front face (13) of the cartridge (3) along a peripheral notch (6). A sliding element (7) connected to the front face (13) pierces a sealing element (8) of the storage reservoir (9). A guiding channel (23) in which the front face (13) is guided in the manner of a piston, opens into a flow zone (12). When the front face (13) has reached the flow zone (12), reaction gas flows around the front face (13) into openings (16) in the tube-shaped sliding element (7). The reaction gas then flows into the storage reservoir (9) where it is mixed with the remaining storage gas.

  • Patent number: 5660803
    Abstract: A liquified gas-containing generator has a casing in which a reaction container containing liquified gas is accommodated. So as to trigger combustion of the liquified gas a puncture element with an overflow channel is driven into the reaction container. The kinetic energy for the puncture element is generated pyrotechnically by initiation of an ignition element. The ignition gases of the ignition element pass via the overflow channel into the interior of the reaction container where these gases induce combustion of the liquified gas. The combustion gases arising thereby pass via the overflow channel out of the reaction container into a hollow space in which the puncture element is arranged. The hollow space is sealed in relation to a discharge passage by a bursting membrane. This bursting membrane bursts open when a minimum pressure of the combustion gases is reached and thereby opens the way for discharge of the combustion gases out of the casing via the discharge passage.

  • Patent number: 5415845
    Abstract: 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 liquid 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 liquid gas channel system so that liquid gas can flow into the combustion chamber.

  • Patent number: 5388860
    Abstract: The safety device has a gas generator for generating gas, which is accommodated in a rigid housing. The housing is open at one side and is sealed in this region by an originally folded sheet of a gas cushion. When igniting the gas generator, the sheet unfolds outwards over the open side and forms the gas cushion filled with gas under pressure. The gas escapes by way of at least one escape opening, formed in a housing wall, with a variable effective cross-sectional area, when the passenger pitches into the gas cushion. The effective cross-sectional area is altered by a temperature-controlled escape opening-adjusting device so that at high gas internal pressures, the cross-sectional area is greater than at lower gas internal pressures. With this arrangement, the temperature-dependent alterations in the catching or impact reduction characteristic of the gas cushion are thereby compensated for.

  • Patent number: 5308370
    Abstract: A filter device for filtering a gas flow, especially for filtering the gases produced by a gas generator for an impact protection cushion, comprises a filter element exhibiting several filter material plies of varying permeability lying in series in the flow direction. The filter element is fashioned as a wrapped member produced by winding up a length of filter material. The length of filter material has sectionally different filter materials, preferably wire mesh of differing mesh widths and metal fiber mats. A wrapped member is formed by winding up this filter material web, the wrapping plies of which consist of different materials with varying filter effects. This filter element wrap is inserted, for example, in the annular interspace between the two tubes of a double-tube gas generator. Owing to the rising pressure of the gas to be cleaned, the wrapped member is compacted with the consequence that its filtering function is improved.

  • Patent number: 5259644
    Abstract: An ignition unit is provided with an internal housing defining a chamber in which an ignition charge and an ignition element igniting the charge are accommodated. The housing defining the chamber consists of a cover and a container which are connected to one another along a circumferential groove. A distributor housing is mounted on to the housing forming the chamber, in which distributor housing gas outlet openings are provided which are closed by a cap-shaped cover of the chamber. The V-shaped circumferential groove represents a predetermined breaking or separation position of the chamber, for which reason the cover is separated from the container when the ignition charge is ignited. The cover moves away from the container into a space until it strikes the upper end of the distributor housing. With its movement relative to the distributor housing, the cover releases the gas outlet openings so that the gases and flames can emerge from the ignition unit.
