To provide a vehicle seat which can suppress rotational motion of a head of a seating crewman with respect to his upper body part without a restriction feeling, a headrest and a headrest control system.SOLUTION: A vehicle seat which comprises a seat back 3 for supporting an upper body part of a seating crewman and a headrest 4 for supporting a head of the seating crewman, and is fitted to a floor. The headrest 4 has: a frame body 41 which is fixed to the seat back 3; a cushion body 50 which is slidable in a longitudinal direction of the seating crewman in a state that the head is supported with respect to the frame body 41; and a motor mechanism 70 which moves the cushion body 50 in the longitudinal direction. A controller 80, which operates the motor mechanism 70 on the basis of a signal from a pressure sensor 54 which detects such a pressure that the head is brought into contact with a surface of the headrest 4, operates the motor mechanism 70 so as to move the cushion body 50 in a direction in which the pressure in the longitudinal direction, which is detected by the pressure sensor 54, is increased in association with movement of the head in the longitudinal direction.SELECTED DRAWING: Figure 2

    【課題】拘束感を伴わずに着座乗員の頭部が上体部に対して回転運動するのを抑制できる乗物用シート、ヘッドレスト及びヘッドレストの制御システムを提供する。【解決手段】着座乗員の上体部を支持するシートバック3と着座乗員の頭部を支持するヘッドレスト4とを備えフロアに取付けられた自動車用シートである。ヘッドレスト4は、シートバック3に固定されたフレーム本体41と、フレーム本体41に対し頭部を支持した状態で着座乗員の左右方向にスライド移動可能なクッション体50と、クッション体50を左右方向に移動させる電動機構70と、を有する。頭部がヘッドレスト4の表面に当接する圧力を検知する圧力センサ54からの信号に基づき電動機構70を作動させる制御装置80は、頭部が左右方向へ移動する動きに伴って圧力センサ54によって検知される左右方向の圧力が高まる方向にクッション体50を移動させるように電動機構70を作動させる。【選択図】図2
