  • Patent number: 12145524
    Abstract: Airbag devices for a vehicle. The airbag cushion may include a gas discharge section, a first tether, and a chamber having an occupant side panel and a steering wheel side panel. The first tether may include a first end directly or indirectly connected to the occupant side panel and second ends connected to the steering wheel side panel. The edge of the gas discharge section can be pulled into the chamber by the taut first tether and the area of the gas discharge section opening with the edge of the gas discharge section pulled into the chamber is smaller than when the first tether is relaxed.

  • Publication number: 20240286574
    Abstract: A vehicular airbag device that comprises: an inflator; and an airbag cushion that inflates and deploys between a steering wheel and an occupant. The airbag cushion includes: an occupant-side panel that deploys to the occupant side and restrains the occupant; a vehicle-side panel that is disposed on the opposite side to the occupant-side panel; and side panels that connect the occupant-side panel and the vehicle-side panel and constitute the side surfaces of the airbag cushion. The side panels comprise a plurality of subpanels. A base material weft that constitutes a central section E1 of the sub-panels extends in a virtual plane S2 that follows the occupant side of the rim of a steering wheel when the airbag cushion is inflated and deployed.

  • Patent number: 11840187
    Abstract: A retaining cover that encapsulates a cushion which is stowed in a bulk stowed form in front of the regular seating position of the vehicle having a side surface retaining part wound around a side surface of the cushion in stowed form, a cloth-like part provided in a manner traversing vertically across the upper surface of the cushion in stowed form, and a weak part provided at a prescribed location on the cloth-like part that divides the cloth-like part to an upper piece and lower piece due to the expansion pressure of the cushion. If the cushion expands and deploys with the occupant in close proximity, the upper piece of the cloth-like part is sandwiched in between the cushion and the occupant, such that the upper piece restrains the upward deployment of the cushion.
