PROBLEM TO BE SOLVED: To achieve improvement of a reclining mechanism of a passenger seat in an aircraft.SOLUTION: A passenger seat 100 in an aircraft includes a seat bottom frame 152 constituting a seating face, and a seat back frame 162 constituting a backrest. Cam followers 240, 242, which are provided on both sides of the seat back frame 162, slide in a cam groove 132 in a spreader 130 which supports both sides of a seat mechanism. When an actuator 200 extends, a link arm 230 rotates in an arrow Rdirection, and consequently, the seat back frame 162 starts reclining, a link plate extends in an arrow Fdirection thereby rotating a headrest frame 172 in a θ direction. Due to this action, a sight line of a passenger is prevented from being out of a video system provided on a back of a front seat.

    【課題】航空機の乗客用シートのリクライニング機構の改良を図る。【解決手段】航空機の乗客用シート100は座面を構成するシートボトムフレーム152、背もたれを構成するシートバックフレーム162を備え、シートバックフレーム162の両側に設けたカムフォロア240、242はシート機構の両側を支持するスプレーダー130のカム溝132内を摺動する。アクチュエータ200が伸長してリンクアーム230が矢印R1方向に回動し、シートバックフレーム162がリクライニングを開始すると、リンクプレートが矢印F1方向に延びて、ヘッドレストフレーム172をθ方向に回動する。この作用によって乗客の視線は前席の背中に設けた映像装置から外れることはなくなる。【選択図】図3
