A seating posture is stabilized for the shoulders of a passenger seated on a vehicle seat. A vehicle seat is provided with a seat back configured to support the seated person from the rear. A shoulder support portion of the seat back configured to support a corresponding one of the shoulders of the seated passenger includes an air cell configured to expand when air is supplied. When the air cell expands, one end portion of the shoulder support portion on the outside in the width direction of the vehicle seat moves more forward than the other end portion of the shoulder support portion on the inside in the width direction.

Vehicle seat

Provided is to stabilize a fixed state of each bag body provided at a vehicle seat and configured to expand to push a corresponding one of the shoulders of a seated passenger. Of a seat back provided at the vehicle seat, each shoulder support configured to support a corresponding one of the shoulders of the seated passenger includes an air cell configured to expand by injection of air. The air cell includes protrusions extending in a predetermined direction and provided at respective end portions of the air bag in the extending direction thereof. The air cell is attached to the inside of the seat back in such a manner that each of the protrusions provided at respective end portions in the extending direction is fixed to a corresponding one of fixing positions separated from each other in the width direction of the vehicle seat.

It is an object to provide a seat of which a seating comfort can be improved. The seat includes a seat cushion pad having an air passage formed inside and an air vent formed at an upper surface thereof, and is configured to allow air in the air passage to blow out through the air vent, wherein the seat cushion pad includes a pad body and a cover member which is disposed over the pad body to form the air passage between the pad body and the cover member and in which the air vent is formed, and a front end portion of the cover member extends downward over a front end portion of the pad body.

A vehicle seat cushion material and a vehicle seat exhibiting excellent moldability and recyclability and providing favorable seating comfortability is described. A cushion material includes a small pad made of resin foam, a pad body integrally stacked on an upper side of the small pad to cover the small pad, made of resin foam, and formed larger than the small pad, and an impregnation layer formed in such a manner that the resin foam of one of the small pad or the pad body is impregnated with an expandable stock solution composition of the other one of the small pad or the pad body and formed at at least a portion of an area between the small pad and the pad body. The impregnation layer is formed on an upper surface and a side surface of the small pad, and the small pad is sterically covered with the impregnation layer.

Vehicle seat cushion material and vehicle seat

Improvement is made in a configuration of a movable portion movable to adjust a length of a seat cushion. A vehicle seat includes a seat cushion having a fixed portion and a movable portion movable relative to the fixed portion for adjustment of a length of the seat cushion, and also includes a notch arranged on the movable portion as a movable portion side engagement portion and an engagement plate piece arranged on the fixed portion as a fixed portion side engagement portion. The engagement plate piece is movable between i) a locking position engaged with the notch to bring the movable portion into an unmovable state, and ii) an unlocking position released from the notch to bring the movable portion into a movable state. The movable portion includes a pressing wire to move the engagement plate piece from the locking position to the unlocking position.

In a vehicle seat including an adjustment device configured to move a front end of a seat cushion to adjust the length of the seat cushion in a front-to-back direction, the adjustment device has a support portion movable back and forth relative to a seat cushion frame, and a roller portion rotatably supported by the support portion and configured such that a pad material is wound around an outer peripheral portion at a front end portion of the seat cushion. The length of the seat cushion is adjustable by a change in an amount of winding of the pad material around the outer peripheral portion corresponding to a rotation of the roller portion during front-to-back movement of the support portion. The outer peripheral portion of the roller portion is made of a soft material.
