  • Patent number: 9969348
    Abstract: Influence from a rear bag section is prevented or suppressed from being applied to an occupant out of position. In a state in which a side airbag inflates and deploys frontward of a side support section of a seat back, a front-rear partition cloth that partitions a bag body into a front bag section and a rear bag section brings an intermediate portion in a vehicle width direction of a front surface of the rear bag section to be recessed toward a vehicle rearward direction so as to be a valley-shaped recessed portion. Through this, even if the side airbag inflates and deploys while the occupant is located frontward of the side support section, it is possible to prevent or suppress influence from the rear bag section to this occupant.

    Abstract: An airbag assembly may include an airbag and an inflator in fluid communication with the airbag. The inflator may have a gas source chamber containing a gas source and a centrifugal flow chamber into which the gas flows from the gas source chamber through a centrifugal flow barrier. As the gas moves through the centrifugal flow barrier, it may be urged to move along a pathway that encircles at least a part of a longitudinal axis of the inflator. The gas may then move toward the longitudinal axis to flow through an orifice of an inward flow barrier. this inward flow may occur at a velocity that is generally too large for entrained particulates. Thus, such particulates may remain in the centrifugal flow chamber. The gas may flow from the orifice into a plenum chamber that releases the gas to the airbag via a plurality of apertures.

  • Publication number: 20150021888
    Abstract: An inflator (10) for a vehicle airbag module comprises an external housing (12) in which a combustion chamber (36) is formed, wherein the inflator (10) can be supported to be oscillating on a body-side component of the vehicle, especially on a component of the airbag module. Inside the external housing (12) a separate balancing weight (58) is arranged for adjusting the vibration behavior of the inflator (10), wherein the balancing weight (58) has no further inflator-specific function. In an airbag module for a vehicle including such inflator (10) the latter is supported by its retaining means on another component of the airbag module so that it is adapted to oscillate about a suspension plane.

  • Patent number: 8910364
    Abstract: A method and apparatus for securing a heat sink/filter positioned between a pressure vessel and a diffuser in an air bag inflator. The pressure vessel is constructed so that upon activation of the inflator of the area of gas exiting the pressure vessel is smaller than the area of gas exiting the diffuser to create pressures in the pressure vessel that are higher than the pressures in the diffuser. This results in deformation of the pressure vessel that is equal to or greater than the deformation of the diffuser to maintain compression of the heat sink/filter between the pressure vessel and the diffuser during activation of the inflator.

  • Patent number: 8893622
    Abstract: An igniter for a passenger vehicle safety airbag module includes a housing with apertured walls, gas-generating tablets filling the housing, and, in direct contact with gas-generating tablets, an initiator containing combustible material. A plurality of four malleable flaps of substantially identical shape and size are secured about the squib in an upstanding circumscribing array with spaced-apart, opposed lateral edges between adjacent of the flaps interconnected by fluid seals in the form of webbing that is structurally less robust than the flaps. The ends of the flaps remote from the squib curl radially inwardly into a spaced-apart edge-to-edge disposition beyond the combustible material. The webbing and the flaps together enclose an interior space and the combustible material. Pressure from the ignition of the combustible material causes the fluid seals to burst and the flaps to pivot outwardly crushing the gas-generating tablets in the housing.

  • Patent number: 8827308
    Abstract: An airbag assembly may include an airbag and an inflator in fluid communication with the airbag. The inflator may have a first chamber containing a first gas source and a second chamber containing a second gas source. A filter module may be positioned to filter and redirect gas flows from the first and second gas sources. The filter module may be constructed by securing a baffle within an interior cavity of a filter medium having a generally tubular shape, prior to installation of the filter module the inflator. The baffle may be supported directly by the material of the filter module, by a bracket, or by a support structure formed of wire thicker than that of the filter medium. The baffle may maintain isolation between the first and second chambers, or may help gas from the first gas source initiate gas provision from the second gas source.
