  • Occupant protection device
    Patent number: 10486639
    Abstract: An occupant protection device includes a vertical air bag. The vertical air bag is deployable downward at least from above a shoulder of an occupant seated in a seat of a vehicle. During deployment, the vertical air bag is bent in such a manner that a deployed direction distal end portion is, at a portion in front of an upper body of the occupant seated in the seat, oriented towards a waist of the occupant. During the development, in a state in which the vertical air bag is bent, the deployed direction distal end portion comes in contact with a frontal portion of the occupant seated in the seat.

  • Vehicle seat
    Patent number: 10449921
    Abstract: A vehicle seat includes a seat back, and an airbag that deploys in the seat back. After having deployed, the airbag has such a shape that a deployment amount, in a front-back direction, of the airbag near an upper part of the seat back differs from that near a lower part of the seat back. The airbag deploys in the seat back in such a way that, after having deployed, the airbag elastically supports an upper body of an occupant and elastically receives an impact force applied to a back surface of the seat back.

  • VEHICLE SEAT AIRBAG SYSTEM AND VEHICLE SEAT
    Publication number: 20190299905
    Abstract: A vehicle seat includes a seat back frame, an elastic installation supporting member installed in the seat back frame, and an airbag within a seat back, the vehicle seat causing the airbag to inflate and develop within the seat back. An inflator is attached to the seat back frame. The seat back frame has a substantially frame shape along a seat back shape. The airbag is provided in the seat back frame in the substantially frame shape. The inflator is attached to at least one of an upper portion and a lower portion of the seat back frame in the substantially frame shape. An inflation and a development of the airbag in the seat back due to an operation of the inflator allows the airbag to elastically support an upper body of a seated person and to elastically receive an impact force.

  • PASSENGER PROTECTION APPARATUS
    Publication number: 20190299896
    Abstract: A passenger protection apparatus includes: a seat belt including a shoulder belt ; an anchor disposed on one side of a seat to hold one end of the seat belt; a buckle disposed on the other side; a tongue that can hold part of the seat belt; a first activation member that reels and unreels the shoulder belt; a first detector that detects or predicts a collision of the vehicle; a second detector that detects a change in a sitting state of the passenger; and a controller that controls activation of the first activation member. When the first detector detects or predicts a collision of the vehicle, the controller controls the first activation member to reel, and stop reeling or unreel the shoulder belt. The controller controls the first activation member to reel the shoulder belt again, based on the change in the sitting state detected by the second detector.

  • PASSENGER PROTECTION APPARATUS
    Publication number: 20190299902
    Abstract: A passenger protection apparatus includes a seat, an activation member, a first detector, a second detector, and a controller. The seat has a seat cushion on which a passenger can sit. The activation member is configured to be activated upward in the seat cushion. The first detector is configured to detect or predict a collision of a vehicle. The second detector is configured to detect a sitting state of the passenger sitting on the seat cushion. The controller is configured to control activation of the activation member. The activation member can change an activation point at which the activation member is activated upward. When the first detector detects or predicts a collision of the vehicle, the controller sets the activation point on a basis of the sitting position detected by the second detector, and activates the activation member upward in the seat cushion at the determined activation point.
