  • Publication number: 20240336132
    Abstract: A steering wheel includes a control unit that executes an acceleration control or a deceleration control of a vehicle based on results of detections by a first contact detecting portion, a second contact detecting portion, a first operation detecting portion, and a second operation detecting portion. The control unit does not execute the acceleration control or the deceleration control based on an operation of a first operating portion when the first operating portion is operated in a state in which the first contact detecting portion is not detecting contact by a driver with a first gripping portion, and does not execute the acceleration control or the deceleration control based on an operation of a second operating portion when the second operating portion is operated in a state in which the second contact detecting portion is not detecting contact by the driver with a second gripping portion.

  • Publication number: 20230242171
    Abstract: A steering wheel includes a grip portion to be gripped during rotation steering; a skin layer being sheet-like and disposed to cover at least an outer peripheral surface side of the grip portion; and a conductive portion using a conductive thread made of a conductive fiber and disposed on an outer surface side of the skin layer. The conductive portion includes a decorative portion formed to decorate the outer surface side of the skin layer using the conductive thread.

  • Patent number: 8424907
    Abstract: An airbag is provided with a vent hole and a patch closing the vent hole. The airbag has a conically-shaped protrusion with the front narrowed when inflation is finished. The vent hole and patch are at the vehicle body side wall of the protrusion. The airbag has the reaction force-receiving contact portion that is partially recessed toward an occupant by receiving a reaction force substantially opposite to the approach direction of the occupant from the reaction force-applying support portion of the vehicle body structure when the occupant is cushioned, at the vehicle body side wall of the protrusion. The patch is positioned where the vent hole can keep closed when the airbag finishes inflating. The patch is not pressed against the reaction force-applying support portion but is spaced from the circumferential edge portion of the vent hole that moves when the reaction force-receiving contact portion is recessed.

  • Patent number: 8414023
    Abstract: An airbag includes a tuck that is formed by tucking a part of the outer circumferential wall toward an interior of the airbag. The tuck includes two opposing walls, a turn-round region that forms a bottom of the tuck and outermost ends of the opposing walls adjacent to and continuing to an outer surface of the airbag. The airbag further includes a temporary joint that joins the opposing walls of the tuck together in such a manner as to disjoint when an inner pressure of the airbag at inflation is increased. The temporary joint is formed into such a line that extends toward the turn-round region and has a first end proximate the outermost ends and a second end in the vicinity of the turn-round region.

  • Patent number: 8414019
    Abstract: The airbag of an airbag apparatus is provided with a slip member that is disposed on the outer surface of an occupant protection area of an airbag main body and can suppress load to an occupant by allowing the airbag main body to slide when the airbag comes in contact with the occupant while being developed and inflated. The slip member is connected to the airbag main body at both left and right edges and a rear-lower edge. In the slip member, a left connecting portion and a right connecting portion for connecting both left and right edges to the airbag main body are connected at a position before and above the center of the occupant protection area, and the rear connecting portion for connecting the rear-lower edge to the airbag main body is connected at a position rear-lower the center of the occupant protection area.
