  • Patent number: 8388021
    Abstract: A passenger seat airbag apparatus includes: an airbag which is housed in a folded state inside an instrument panel, and which inflates toward a passenger with a supply of gas during a frontal collision of a vehicle, and which has a vent hole that can be opened and closed; a tether whose first end is linked to a periphery of the vent hole in the airbag, and which closes the vent hole due to tension that is caused when the airbag inflates; an actuator which has a first hole that a second end of the tether is passed through, and which discontinues a linked state of the tether by cutting the tether if a predetermined condition is satisfied; and a protective member that is attached to the actuator so as to cover at least an edge portion of the first hole, and that is interposed between the edge portion and the tether.

  • Patent number: 8128121
    Abstract: In a knee airbag device mounted on a steering column, an opening that provides a workspace when a wire harness connector that extends from the steering column is connected to a wiring connector provided at one end portion of an inflator is formed in a side wall of a lower cover (or column cover) opposite the connector of the inflator. By using the opening, the connector of the wire harness may be easily connected to the connector of the inflator, which is mounted transversely with respect to the axial direction of the steering column. The opening is closed by a lid.

  • Patent number: 8056922
    Abstract: The invention has the object of increasing workability of an attachment operation of a knee airbag module of a column-mounted knee airbag device. When fixing a knee airbag module to a lower portion outer peripheral surface of a steering column, it is possible to perform the fixing from a vehicle upper side and a vehicle rear side of the steering column, using a space between an instrument panel (interior member) at a vehicle upper side of the steering column and a combination switch provided at a rear end side of the steering column. Accordingly, when performing an attachment operation of the knee airbag module to the steering column, an operator does not have to enter from a lower side of the steering column.

  • Patent number: 7832760
    Abstract: A vertical cell is formed in a forward inflation section of an airbag. The vertical cell extends in a vehicle height direction at the rear of a pillar, and communicates through a bottom end of the vertical cell with a horizontal cell. When the inflation section is deployed, the folded horizontal cell or the lower side part of the airbag is pulled back toward the passenger compartment with respect to the side window opening. Accordingly, the horizontal cell deploys to an area below a bottom edge of the side window opening or a beltline in the passenger compartment on the inner side of a front side door.

  • Patent number: 7806433
    Abstract: A supplemental inflation part is formed in a portion of an upper-end side inflation section of an airbag, the portion overlapping a B-pillar garnish. The supplemental inflation part has a semicircular shape that forms a push-out part. Folding the push-out part allows the upper-end side inflation section to be inflated largely at the initial stage of deployment of the airbag. Thus, the airbag is pushed toward the passenger compartment with greater force upon its deployment. Therefore, a terminal part of a headliner that covers the folded airbag is largely opened so that the airbag deploys smoothly downward along the side of the vehicle body in the passenger compartment without interference from the top end of the B-pillar garnish.
