  • Patent number: 6991258
    Abstract: A frontal air bag system for a vehicle includes an air bag module having a housing for mounting to vehicle structure of the vehicle and an air bag operatively connected to the air bag module. The frontal air bag system also includes an inflator disposed in the housing for inflating the air bag with an inflation gas. The frontal air bag system further includes at least one tether interconnecting the air bag and either one of the housing and the inflator to cause some of the inflation gas to vent through the housing to atmosphere.

  • Patent number: 5509686
    Abstract: An air bag assembly for an inflatable passenger vehicle restraint system comprises an inflatable air bag, a thrust neutral inflator for generating pressure gas and a reaction canister. The inflator has a cylindrical casing with a plurality of holes on opposite sides for discharging the gas to inflate the air bag. The reaction canister houses the inflator and has a part-cylindrical bottom wall terminating in upstanding side walls which operatively connect the inflator to the air bag. A plurality of aspiration holes are formed in the reaction canister side walls. A part-cylindrical baffle is mounted in the canister between the inflator and the bottom wall and has an outlet to direct gas discharged from the inflator away from the walls and to the air bag. Ambient air is aspirated through the aspirator holes upon gas delivery from the inflator discharge ports to augment the volume of gas delivered to the air bag. The aspirator holes also serve as pressure relief vents for the air bag.

  • Patent number: 5498025
    Abstract: An air bag assembly includes an air bag module subassembly for installation in an air bag housing having a housing opening through which an air bag deploys. The air bag module subassembly includes a subassembly retainer which captures and holds an inflator and an air bag retainer in position relative to the housing and enables facile installation of the air bag module subassembly into the housing via the housing opening such that the subassembly retainer is restrained by the housing to prevent release of the air bag retainer.

  • Patent number: 5468011
    Abstract: An air bag module comprises an inflatable air bag, an inflator and a container for housing the inflator and the air bag. The container comprises an elongated reaction canister having a closed housing formed of a U-shaped body with end walls defining a rectangular top gas discharge opening. An air bag deployment chute comprises a rectangular body having a bottom gas transfer opening mating with the canister opening and a top air bag deployment opening. Cooperating flanges on the top side of the canister and on the bottom side of the chute are interengageable upon endwise sliding to assemble the chute to the canister. Surfaces on the chute and canister engage to locate the chute bottom opening in registry with the canister opening. Cooperating tabs on the canister are received in slots formed in the chute upon assembly and are deformed to lock the chute to the canister.

  • Patent number: 5433471
    Abstract: An air bag module comprises an air bag, an air bag retainer ring, a housing, an elongated inflator, and an inflator container. The retainer ring is secured to the air bag about its opening and has a mounting flange. The housing has spaced side and end walls defining a rectangular air bag storage chamber for storing a folded air bag and which has an upper air bag deployment opening and a bottom gas discharge opening. A mounting flange extends from each of the side walls, and four spaced straps span the gas discharge opening to interconnect the side walls and form an inflator cradle. The inflator is located on the straps and comprises a substantially cylindrical case having a plurality of gas discharge holes, a cap end and a blank end. The container comprises a U-shaped body forming bottom and side walls, two spaced raised ribs formed in the bottom wall, and a mounting flange extending from each of the side walls. Three pairs of aligned mounting apertures are formed in all of the mounting flanges.

  • Patent number: 5431432
    Abstract: A container for an air bag inflator comprises an open-ended cylindrical aluminum or magnesium extrusion having circumferentially-spaced internal ribs, an axial gas discharge opening and a pair of grooved mounting flanges flanking the opening. A cylindrical inflator is inserted through one end of the container on the ribs. An air bag deployment chute includes depending mounting flanges. An air bag, which includes mounting hems having loops, is placed in the chute. A U-shaped retainer is inserted into the hem loops and into the chute channels. This assembly is slid endwise into the container grooves. An end plate is attached to the retainer ends and has a notch to engage an orientation lug on the inflator. In another embodiment, the chute is omitted and the air bag hem loops each receive a mounting rod which are inserted radially into the container grooves. A mounting plate has flanges that are bolted to the container flanges, clamping flanges of an air bag cover in between.

  • Patent number: 5380038
    Abstract: According to the invention, a vehicle body has a passenger seating position and an inflatable restraint system for restraining a passenger. The inflatable restraint system includes an inflatable restraint module mounted to the vehicle body. The module includes a module opening through which an inflatable restraint cushion is deployed. The module includes an inflator for discharging gas out through the module opening to inflate the cushion. The cushion includes a forward wall and a rearward wall. The longitudinal centerline of the module opening is offset in a lateral offset direction, such as inboard or outboard, from the longitudinal centerline of the passenger seating position so that initial cushion inflation occurs offset of the centerline of the passenger seating position. A first tether device extends diagonally from the forward wall towards the lateral offset direction to the rearward wall.

  • Patent number: 5364124
    Abstract: An air bag assembly is mounted in a vehicle instrument panel recess located below an opening in the instrument panel upper surface which has a removable cover door normally closing the opening. The air bag assembly comprises an inflator, an air bag, a container mounting the inflator at its bottom and housing the folded air bag atop the inflator, and an air bag deployment chute. The deployment chute is a fabric rectangular tube having one end attached to the container around its deployment opening. The deployment chute is folded atop the air bag. A fabric tether connects the lower edge of the chute outer end to the container and is shorter than the tube. Upon actuation of the inflator, the deployment chute forces open the instrument panel door and extends outwardly of the instrument panel opening. The tether forces the chute to arch rearwardly and downwardly of the instrument panel opening.
