PROBLEM TO BE SOLVED: To ensure both elasticity and hardness of a vehicle seat and to appropriately switch the state of the vehicle seat according to a situation.SOLUTION: A seat device 100 is provided with: a vehicle seat that has a cushion material provided with a plurality of recesses in a bottom part; a plurality of air cells 20 bulged by sealing in compressed air; and a fluid supply mechanism 30 that supplies a fluid to the plurality of air cells 20. Some of the recesses are provided to the bottom part of a part of the cushion material positioned in a seating part on which the hip pf an occupant rests in the vehicle seat. Each of the air cells 20 bulges in corresponding one of the recessed parts. The fluid supply mechanism 30 bulges some or all the air cells 20 by supplying he compressed air to some or all the air cells 20, and changes the air cells 20 to be bulged by switching the supply destination of the compressed air.SELECTED DRAWING: Figure 3 【課題】乗物用シートの弾性及び硬度の双方を確保すると共に、状況に応じて乗物用シートの状態を適切に切り替える。【解決手段】底部に複数の凹部が設けられたクッション材を有する乗物用シートと、圧縮空気が封入されることで膨出する複数のエアセル２０と、複数のエアセル２０に対して流体を供給する流体供給機構３０と、を備えた座席装置１００において、複数の凹部の一部は、クッション材のうち、乗物用シートにおいて乗員の臀部が載る着座部に位置する部分の底部に設けられている。各エアセル２０は、複数の凹部のうち、対応する凹部内で膨出する。流体供給機構３０は、一部又は全部のエアセル２０に対して圧縮空気を供給することで、一部又は全部のエアセル２０を膨出させ、圧縮空気の供給先を切り替えることで、膨出させるエアセル２０を変える。【選択図】図３
