PROBLEM TO BE SOLVED: To provide a seat device for a vehicle which can adjust a discharge speed of internal air filled in an airbag by a simple constitution.SOLUTION: A seat device 20 comprises a plurality of airbags 10 arranged inside a seat, and a flow passage L having a common zone LC, and communicating with the airbags 10. The seat device 20 also comprises a plurality of intake valves 25 which are arranged in a flow passage position being an upstream side of the airbags 10 at the pressure-sending of air to the airbags 10, a plurality of exhaust valves 26 (26a to 26c) which are arranged in the flow passage position communicating with the common zone LC of the flow passage L, and a control device for controlling operations of the intake valves 25 and the exhaust valves 26. When discharging the internal air of the airbags 10, the control device adjusts a discharge speed of the internal air by selectively releasing the exhaust valves 26.SELECTED DRAWING: Figure 3

    【課題】簡素な構成にて、空気袋に充填された内部空気の排出速度を調整することのできる車両用シート装置を提供すること。【解決手段】シート装置20は、シートの内側に設けられる複数の空気袋10と、共有区間LCを有して各空気袋10に連通する流路Lと、を備える。また、シート装置20は、各空気袋10に対する空気の圧送時において各空気袋10の上流となる流路位置に配置される複数の吸気バルブ25と、流路Lの共有区間LCに連通する流路位置に配置される複数の排気バルブ26(26a〜26c)と、これら各吸気バルブ25及び各排気バルブ26の作動を制御する制御装置と、を備える。そして、制御装置は、各空気袋10の内部空気を排出する際、各排気バルブ26を選択的に開放することにより、その内部空気の排出速度を調整する。【選択図】図3
