  • Publication number: 20200001817
    Abstract: An airbag 20 of an airbag device 10 includes a center deployable portion 22 that is configured to be deployed obliquely rearward toward a center in a vehicle width direction of a vehicle 1 when expanded and deployed upon receiving supply of gas. The center deployable portion 22 has a head receiving surface 22a which receives the head 3a of an occupant 3 moving obliquely forward to come into contact with the head receiving surface 22a. A patch cloth 30 is coupled, at both ends thereof in the vehicle width direction, to the head receiving surface 22a, while having a portion which is slack with respect to the airbag 20.

  • Patent number: 9902359
    Abstract: Disclosed is an airbag apparatus which comprises: a first airbag configured to be deployed rearwardly from a steering wheel during an oblique collision of a vehicle; and a second airbag configured to be deployed rearwardly and upwardly from a position below a steering shaft during the oblique collision of the vehicle. The second airbag comprises an upward deployment portion capable of, in its deployed state, extending upwardly via a lateral side of the steering shaft, wherein the upward deployment portion is disposed between a lateral portion of the first airbag in its deployed state and an instrument panel.

  • Patent number: 9694782
    Abstract: The present application discloses a control device for an automatic transmission mounted in a vehicle including idling stop means for automatically stopping an engine when a predetermined stop condition is satisfied, and restarting the engine when a predetermined restart condition is satisfied in an engine automatically stopped state. The control device for the automatic transmission includes a first friction element and a second friction element fastened in a starting stage of the automatic transmission; and hydraulic-pressure controlling means for controlling hydraulic pressure for fastening the first and second friction elements. The first friction element includes a return spring that urges a piston of the first friction element to a release side. The second friction element includes a friction plate, a pressing piston that presses the friction plate, and a clearance adjustment piston that supports the pressing piston so as to allow relative movement of the pressing piston.

  • Publication number: 20160200281
    Abstract: An airbag apparatus includes a first airbag (10) that deploys rearward from a position in front of an occupant (D) upon an oblique collision and a second airbag (20) that deploys so as to cover a cabin side wall upon an oblique collision. The second airbag (20) includes a wraparound portion (23) which deploys so as to protrude towards the inside of the cabin at a position further on the front side from an outer edge portion (10a) that is a portion, opposing the cabin side wall, of a peripheral edge of the deployed first airbag (10) to restrict the outer edge portion (10a) from being displaced forward.
