PROBLEM TO BE SOLVED: To provide a vehicle seat in which the change actuation in the seating face angle of a seat cushion interlocks in response to the change of the seat back angle of a seat back in a necessary range of the angular adjustment area adjustable in the seat back angle.SOLUTION: A vehicle seat comprises: a recliner (reclining mechanism) in which an optional angle of an angular adjustment area is preset as a standard angular position 1N; a turning shaft 32 (a seating face attitude change mechanism) capable of changing a seating face angle to the installation site of a vehicle; and an interlocking change means 40 in which the change actuation of the seating face angle in a seat cushion interlocks in response to the change of a seat back angle of a seat back. The change means 40 configures a noninterlocking range in which a pressing part 50 does not press a pressed part 60 when the seat back falls forward from the standard angular position 1N, and an interlocking range in which the pressing part 50 presses the pressed part 60 when the seat back falls rearward from the standard angular position 1N.SELECTED DRAWING: Figure 6 【課題】シートバックの背凭れ角度を調整可能な角度調整領域のうち必要な範囲において、シートバックの背凭れ角度の変化に応じてシートクッションの座面角度の変更作動が連動する乗物用シートとする。【解決手段】角度調整領域のうち任意の一角度を標準角度位置１Ｎとして予め設定されているリクライナ（リクライニング機構）と、乗物の装着部位に対して座面の座面角度を変化可能とする回動軸３２（座面姿勢変更機構）と、シートバックの背凭れ角度の変化に応じてシートクッションの座面角度の変更作動が連動して行われる連動変更手段４０と、を有し、連動変更手段４０は、シートバックが標準角度位置１Ｎよりも前倒れする際に押圧部５０が被押圧部６０を押圧しない非連動範囲と、標準角度位置１Ｎよりも後倒れする際に押圧部５０が被押圧部６０を押圧する連動範囲を構成する。【選択図】図６
