SUPPORT SEAT

To provide a support seat that allows a user to take a more correct seating posture.SOLUTION: A support seat 10 includes: a seat part 21 that supports the hip of a user; a backrest 22 that supports the back of the user; a first air bag 31, a second air bag 32 and a third air bag 33 that expand with air supply; and a control device 80 that controls a pump 71 which supplies air to the first air bag 31, the second air bag 32 and the third air bag 33. The first air bag 31 is arranged at a portion that corresponds to the sacrum of the user seated in the seat part 21. The second air bag 32 is arranged at a portion that corresponds to the lumbar spine of the user seated in the seat part 21. The third air bag 33 is arranged at a position deviating in the width direction with respect to the first air bag 31 and the second air bag 32. The control device 80 supplies air to the first air bag 31, the second air bag 32 and the third air bag 33 so that the pressing force of the first air bag 31 and the second air bag 32 become greater than the pressing force of the third air bag 33.SELECTED DRAWING: Figure 1 【課題】より正しい着座姿勢をユーザに取らせることができるサポートシートを提供する。【解決手段】サポートシート１０は、ユーザの臀部を支持する座部２１と、ユーザの背中を支持する背もたれ２２と、給気により膨張する第１空気袋３１、第２空気袋３２及び第３空気袋３３と、第１空気袋３１、第２空気袋３２及び第３空気袋３３に給気するポンプ７１を制御する制御装置８０と、を備える。第１空気袋３１は、座部２１に着座するユーザの仙骨に対応する部位に配置され、第２空気袋３２は、座部２１に着座するユーザの腰椎に対応する部位に配置され、第３空気袋３３は、第１空気袋３１及び第２空気袋３２に対して、幅方向にずれた位置に配置される。制御装置８０は、第１空気袋３１の押圧力及び第２空気袋３２が第３空気袋３３の押圧力よりも大きくなるように、第１空気袋３１、第２空気袋３２及び第３空気袋３３に給気する。【選択図】図１
