  • Patent number: 10589646
    Abstract: A vehicle seat includes: a power tilt mechanism; a seat front panel that forms a part of a front portion of a seat cushion, bridges a right and left pair of side frames of the seat cushion, and is configured to be rotatable by the power tilt mechanism about a tilt central axis that is provided in linking portions, at which the seat front panel is linked to the side frames, an axial direction of the tilt central axis coinciding with a seat width direction; and a control device that is connected to the power tilt mechanism, the control device being configured to activate the power tilt mechanism to cause the seat front panel to rotate in a seat upward direction, in a case in which a vehicle impact in which an occupant sitting on the seat cushion will move in a seat forward direction has been predicted.

  • Patent number: 10583798
    Abstract: In a vehicle seat, a gas generating device of a side airbag apparatus is attached to the inside of an outer side frame in a seat-width direction. When a seated occupant is a three-dimensional mannequin of AM50, a portion of the gas generating device overlaps a back pan of the three-dimensional mannequin as viewed in a seat front-rear direction. Here, in a plan section of a seat back in a range in which the gas generating device is positioned in a seat up-down direction, when an imaginary line overlapping a section of the back pan is moved back toward a seat rear side until the imaginary line comes into contact with a side spring portion of a seat back spring, the gas generating device is positioned rearward of a moved-back imaginary line in the seat front-rear direction and outward of the moved-back imaginary line in the seat-width direction.

  • Patent number: 10358109
    Abstract: A vehicle seat includes an outer side frame, an inflator, and a side airbag including a front chamber and a rear chamber. The inflator is configured such that the rear chamber inflates and deploys faster at a higher pressure than a front chamber, and the side airbag is stored in a side portion in a state in which the side airbag straddles the outer side frame from a vehicle front side in a vehicle-width direction and a portion of the side airbag including the front chamber is folded outward of the outer side frame in the vehicle-width direction.

  • Patent number: 10343638
    Abstract: In a vehicular seat installed with a side airbag device, an inside bag completes inflation and deployment earlier than a side air bag body, on the inner side of the side airbag body in the vehicle width direction, and presses an occupant inward in the vehicle width direction. The inside bag inflates and deploys at an upper level than the abdominal region of the occupant. Further, reaction force is applied inward in the vehicle width direction from a reaction force plate supported by an outer side frame, to the inside bag. The reaction force plate extends in a vehicle front-back direction, and extends toward the front of the vehicle beyond a front edge portion of the outer side frame.
