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.

To make a rotatable vehicle seat be rotatable in a small space, in a vehicle seat () including a seat cushion () provided on a floor () of a vehicle and a seat back () provided on the seat cushion, the seat cushion is provided on the floor so as to be rotatable about a selected one of multiple rotation axes (A) extending substantially vertically. Preferably, a rotation device () is provided between the floor and the seat cushion, the rotation device being configured to enable rotation about the selected one of the multiple rotation axes while restricting rotation about any of the remaining rotation axes.

A method of assembling a vehicle seat is provided, comprising: providing a seat back frame; forwardly movably connecting a headrest for supporting a head of a seat occupant to the seat back frame; mounting a rear-end collision detector to the seat back frame at a position behind the seat occupant, operatively connecting the rear-end collision detector to the headrest; disposing a link member at a position lateral to the rear-end collision detector; forming a front extending portion that inwardly extends in a right-to-left direction at a front end of a lateral face of the side frame; and forming a rear extending portion that inwardly extends in the right-to-left direction; wherein a protruding portion is formed from a portion of the lateral face of the side frame that faces at least the part of the bracket, the link support shaft being disposed at a same height as the protruding portion.

Method for assembling vehicle seat with cushion plate

Provided is a vehicle seat that is rotatable relative to a vehicle body and can prevent a collision between an object located around a seat body and an occupant by airbags. A vehicle seat includes: a seat body () supported by a vehicle body () so as to be rotatable around a substantially vertical axis; a pair of airbags () provided on either lateral side edge of the seat body and configured to deploy to respective lateral sides of an occupant seated on the seat body; a rotation angle detecting device () provided on the seat body and configured to detect a rotation angle of the seat body relative to the vehicle body; and a control device () configured to control deploying operation of the respective airbags independently of each other. The deploying operation includes a deploying amount and/or a deploying timing. The control device is configured to individually control the deploying operation of the pair of airbags according to the rotation angle detected by the rotation angle detecting device.

Provided is a vehicle seat that detects an alertness level of the driver, urges the driver to be alert, and permits the transition from autonomous driving to manual driving when the driver is alert enough for the manual driving. A vehicle seat () configured to be mounted on a vehicle () provided with a vehicle control device () that can be selectively switched from autonomous driving to manual driving comprises: a seat body () configured to support a driver; a seat control unit () configured to communicate with the vehicle control device; an alertness level sensor () provided on the seat body for detecting an alertness level of the driver; and a rousing unit () provided on the seat body for providing a stimulus for urging the driver to be roused, wherein the seat control unit is configured to detect the alertness level of the driver according to a signal from the alertness level sensor upon receiving a start signal that is produced by the vehicle control device when a transition from the autonomous driving to the manual driving is to be initiated, to activate the rousing unit when the alertness level is lower than a first alertness level threshold value, and to permit the vehicle control device to perform the transition from the autonomous driving to the manual driving when the alertness level is equal to or higher than the first alertness level threshold value.

A conveyance seat unit lessens a neck load applied to an occupant based on body shape, sex, or the like of the occupant when a rear load acts on a conveyance. The conveyance seat unit includes: a seat having a support portion that supports the occupant from behind; a state adjustment mechanism configured to adjust a state of a neck load adjustment portion, of the support portion, that affects the neck load applied to the occupant when the rear load acts on the conveyance; and an electronic control unit (ECU) that controls the state adjustment mechanism. The ECU acquires occupant information on the body and the sex of the occupant and controls the state adjustment mechanism according to the acquired occupant information to change the state of the neck load adjustment portion, which has been adjusted by the state adjustment mechanism, according to the content of the occupant information.

Conveyance seat unit

A vehicle seat whose state is changeable when a rear load is input to a conveyance includes a rotary member configured to move from an initial position in association with the state change, and a lock pin configured to restrict movement of the rotary member. Where a load on the vehicle seat from an occupant based on the rear load changes according to the occupant's physique, weight, etc., when the load is less than a predetermined value and the rotary member moves from the initial position to reach a first position, the lock pin holds the rotary member at the first position. When the load is equal to or greater than the predetermined value, the rotary member, after having reached the first position, moves toward a second position beyond movement restriction by the lock pin, the second position being apart further from the initial position than the first position.
