摘要： A variable volume airbag cushion. The cushion includes a front wall having a central region for contacting the passenger, and a periphery. This periphery is connected to a periphery of a rear wall. The rear wall includes a central inlet operatively connected to a gas generator. The generator provides gas to initially inflate the volume defined between the front wall and rear walls. The rear wall includes at least one pleat therein, with the pleat held by a frangible connection such as a tear seam. It is preferred that the pleat be folded over to lie against the remainder of the rear wall, and secured thereto, again by a frangible connection. The pleats reduce the size of the rear wall, and therefore the volume between the front and rear walls. The frangible connections will rupture above a predetermined gas pressure in the cushion. This permits the rear wall to expand to its full size, increasing the volume between the front and rear walls. The cushion may therefore compensate for increase gas production due to higher ambient temperatures, or may be used with an adaptive gas generator which produces larger or smaller amounts of gas based upon various conditions.
摘要翻译：一个可变体积的气囊垫。衬垫包括具有用于接触乘客的中心区域的前壁和周边。该周边连接到后壁的周边。后壁包括可操作地连接到气体发生器的中心入口。发电机提供气体以最初膨胀在前壁和后壁之间限定的体积。后壁在其中包括至少一个褶皱，褶皱由诸如撕裂缝的易碎连接保持。优选地，将褶皱折叠以抵靠后壁的其余部分，并且通过易碎的连接再次固定到其上。褶皱减小了后壁的尺寸，因此减小了前壁和后壁之间的体积。易碎连接将破裂在衬垫中的预定气体压力之上。这允许后壁扩展到其全尺寸，增加前壁和后壁之间的体积。因此，衬垫可以补偿由于较高的环境温度而增加的气体产量，或者可以与基于各种条件产生更大或更少量的气体的自适应气体发生器一起使用。

摘要： An airbag inflator having a reduced area filter and cartridge-loaded generant. The inflator has a tubular housing with a plurality of exit ports in a limited angular extent. A filter having the general shape of a section of a tube is received within the housing within the extent of the exit ports. The filter has lateral edges which are compressed to reduce the thickness of the filter along these edges, increasing the inner diameter of the filter. A hollow cylindrical cartridge may be provided to house a quantity of pyrotechnic gas generant. The cylindrical cartridge is received within the housing, with the filter interposed between the cartridge and the exit ports. The increased inner diameter of the filter permits the use of a larger diameter cartridge compared to a filter which has not had its lateral edges compressed, which in turn permits a shorter inflator to hold the same volume of generant. The housing may be formed by double impact extrusion to have two separate interiors, each having a generant cartridge. This will permit the cartridges to be fired separately, providing adaptive performance for the inflator.

摘要： A method and apparatus for igniting a pyrotechnic gas generator, or inflator, such as those used in automotive airbag systems is disclosed. The ignition system uses a flammable gas to ignite the pyrotechnic gas generant. The flammable gas can be stored either throughout interior free space in the inflator or it can be maintained in a separate sealed container either separately or jointly with the pyrotechnic gas generant. The method and apparatus offer both cost savings and a reduction in delay time over conventional pyrotechnic ignition systems.

摘要： A generant cartridge for incorporation into an airbag inflation module, is produced by shrink wrapping a plastic envelope around gas generant pellets or wafers thereby completely encapsulating the gas generant in a hermetically sealed envelope. The gas generant cartridge may be prepared at one location and brought to an assembly line located at another location. As a result, the assembly of the generant into the module inflator is simplified. The gas generant may be shrink wrapped with an entire filter assembly or with only a portion of the filter assembly and then inserted into an inflator. A booster charge for rapid ignition of the gas generant may also be inserted in the cartridge.

摘要： A gas generator for vehicle occupant restraint systems comprises an elongated housing having gas outlet openings, a sealed, rupturable gas generant cartridge positioned within the housing, and pyrotechnic gas generant contained in the cartridge in the form of a plurality of wafers having openings defining a central passage. An igniter capsule mounted at one end of the housing has an exit opening juxtaposed the sealed gas generant cartridge and the central passage of the gas generant therein. The igniter capsule contains ignitor material, and an initiator and initiator charge. The initiator ignites the ignitor material which expels a fireball of hot combustion products from the capsules exit opening, rupturing the sealed cartridge and igniting the gas generant charge to produce gas for inflating an air bag. A rupturable seal is provided over the exit opening of the ignitor capsule and a nozzle directs hot combustion products to the gas generant cartridge. The initiator charge is auto ignitor material for operating the gas generator if it is exposed to fire. The ignitor capsule comprises overlapping metal parts, and is mounted as a closure of the elongated housing. The gas generant cartridge is placed in the housing surrounded by filtering and cooling screens. One end of the rupturable gas generant cartridge adjacent the ignitor capsule outlet is scored for rupturing inwardly to admit the ignitor fireball. The cartridge contains wraps of filter screen to provide structural rigidity, and additional filter and cooling materials surround the cartridge.

摘要： A lightweight and inexpensive inflator for a vehicle passenger side restraint bag. The inflator includes a thin igniter housing member and also includes a thin arcuate barrier member which defines a combustion chamber for holding gas generant material for combustion thereof. The inflator housing has generated gas outlet apertures only on one side and the barrier member faces that side so that generated gas is directed toward the other side of the housing and is then redirected through a filter pack to the apertures. The filter pack includes a plenum providing screen which is blocked to the entrance of redirected gas by the pressing of other layers of the filter pack against the housing wall whereby the redirected gas is directed through a fibrous filter member before being directed into the plenum and out through the housing apertures. After leaving the housing apertures, the generated and filtered gas is directed through another filter pack which is disposed along the wall of the bag retainer prior to the gas flowing into the airbag.

摘要： An impact extruded perforated aluminum housing contains a two-stage gas generator having a perforated bulkhead positioned between the stages. Each stage includes a combustion chamber having an igniter and pyrotechnic charge therein with cooling and filter screens surrounding the combustion chamber. The igniter of the first stage is fired by a squib responsively to an external electrical signal. A rupturable barrier and a ball valve associated with the bulkhead control the flow of gas through the bulkhead and provide mechanical timing for ignition delay in the firing of the second stage after the first stage has been fired, and also provide pressure control after ignition of both stages to prevent repressurizing the first stage. A rupturable foil barrier surrounding the combustion chamber in the first stage promotes a rapid rise in pressure therein and thus breakout sooner therefrom of gas to an airbag to be inflated. A rupturable foil barrier surrounds the cooling and filter screens in the second stage and delays the breakout of gas therefrom to the airbag as the pressure rises, the rate of which pressure rise is less than that at which the pressure in the first stage rises. The thickness of the foil barrier surrounding the combustion and filter screens is selected to be sufficiently less than that of the foil barrier surrounding the first stage combustion chamber so as to achieve substantial equalization of pressure in the first and second stages.

摘要： A safety igniter for flares is attachable to the flare parachute by a lanyard that operates the igniter when the parachute opens. The igniter is packaged in a housing that is mounted into the flare casing adjacent the ignition surface of the flare candle. The housing has two contiguous bores of different diameters, the larger bore containing a primer-charge holder and a firing-pin holder, both of which are movable in the bore. The primer-charge holder is retained adjacent the shoulder at the juncture of the bores, so that its motion is rotational only; while that of the firing-pin holder is primarily a forceful axial motion produced by the parachute lanyard, to which it is operatively attached. The primer charge is normally out of angular alignment with the firing pin and the chamber in the housing containing a pyrotechnic charge, but is aligned with a dead-air chamber. However, means for rotating the primer-charge holder is actuated in response to axial motion of the firing-pin holder, so that the primer charge is brought into alignment with the firing pin and pyrotechnic charge before it is struck by the firing pin. In one embodiment, all three of these items are normally mutually out of angular alignment, so that the firing-pin holder must also be rotated. When the firing pin strikes the primer charge, it discharges into the pyrotechnic material which, in turn, discharges hot gases onto the ignition surface of the flare candle.
