    摘要： A gas generant body having a plurality of alike, flat-surfaced projections equally spaced and radially equidistant about the periphery of one or both sides of the body. The spaced projections are defined by curved or arcuate walls emanating from the center of the generant body which flare outwardly to the body's perimeter, each having an angular arc length greater than the space therebetween. The outer edge of each projection is preferably contiguous with the perimeter of the body. When the projections are on both sides, as is preferred, the projections on one side are preferably in a staggered or offset relationship to those on the other side. A washer-shaped wafer disc is the most preferred overall generant body form. A stack or assembly of the multiprojection generant wafers may be formed into an array for use in a gas generator for an automobile gas bag inflator. Each generant wafer acts as its own spacer, can be assembled independent of orientation, will not mesh or interlock with adjacent wafers and does not need extra inflator hardware.

    摘要： Reinforced ceramic unitary filters for air bags. The filters have a first layer having a high porosity, and a second layer having a low porosity. The first layer is preferably formed of low-cost ceramic grit sintered into a rigid mass, or a rigid reticulated ceramic. The second layer is formed of metal particles, and provides increased strength for the brittle ceramic. The metal particles may be formed onto the second layer and then sintered in place. Alternatively, the second layer may be formed separately and secured in position on the first layer. As a third alternative, the second layer may be applied by plasma arc deposition upon the first layer. The metal particles provide increased strength to the filter, as well as providing a fine filtering layer. The metal layer can also place the ceramic in compression to pre-load the ceramic layer for increased resistance to breakage.

    摘要： Components of a vehicle airbag gas generator, or inflator, are coated with reactivity resistant materials to protect them from deterioration caused by contact with the high temperature, reactive gases generated by recently developed non-azide high reactive temperature gas generating materials. Suitable coatings include those produced from ceramics and reactivity resistant metals. These coatings also provide long term protection of the components from deterioration caused by the environment/atmosphere within the inflator.

    摘要： A unitary rigid filter for use in a high temperature, high pressure application in a pyrotechnic airbag inflator includes a matrix structure formed of porous carbonaceous foam material coated with silicon material and having a high thermal conductivity coefficient for absorbing heat from the gases generated on ignition of a pyrotechnic material. The porous, carbonaceous foam has a porosity or permeability of approximately 40 ppi to 80 ppi and a thin, sheet-like liner of porous, ceramic paper is mounted on the body of the foam matrix structure for improving operational characteristics.

    摘要： A pyrotechnic inflator for an air bag includes a housing for containing gas generating material for inflating an air bag. The housing has a wall formed of rigid, porous material and serves both as a filter for entrapping contaminants from the gas that is generated within as the gas passes outward through the wall into the air bag and cools the gas by absorbing heat therefrom. Gas generating material and an ignition train is hermetically sealed in a bag or packet inside the porous housing which serves triple duty as a solid pyrotechnic container, a gas filter and a gas cooler.

    摘要： A pyrotechnic air bag inflator utilizing non-azide gas generating material such as mixtures of copper oxide and amino tetrazol includes a unitary, rigid, drop-in type, filter for cooling and filtering high temperature, high pressure corrosive gas generated when the air bag inflator is activated to inflate an associated air bag. The filter comprises a reticulated structure formed of strong, porous, metal, metal alloy or ceramic material having a high thermal diffusivity and surface area for absorbing heat from the gas and defining a plurality of tortuous passages for entrapping contaminants from the gas passing through the filter.

    摘要： An airbag inflator with venturi effect cooling and gas supplement. The inflator includes a housing having a quantity of gas-producing fuel therein, and possibly a stored gas also, along with appropriate igniters. These materials are stored within a gas production chamber of the housing. The gas leaving this chamber travels through the housing to an exit port on the housing. Intermediate the gas production chamber and the housing exit port is a venturi section of the housing. This section reduces the pressure of the gas, and thus the pressure at the interior end of draw vents opening onto the venturi section. The vents therefore draw outside air into the housing to mix with the gas. This cools the gas to the desired temperature, and also supplements the gas exiting the housing. As such, the need for a heat sink to cool the gas is reduced or eliminated. Furthermore, since the cushion is inflated with a mixture of gas and air, the amount of gas typically needed is reduced by the amount of added air. This permits the amount of fuel to be reduced, thus reducing cost and weight.
