To provide a seat temperature control system that can use an air blower for generating hot air and prevent the efficiency of a heater from being reduced when the air blower is driven while the heater is driving.SOLUTION: A seat temperature control system includes a seat cushion, a seat bag 200, and a control device. At least one of the seat cushion and the seat bag includes a body 210, an air blower 230, a heater 220, a temperature adjustment member 240, a selector valve 250 switchable between a first orientation in which communication between a support surface intake port 211h and the air blower 230 is blocked and the other intake port 212h and a supply port 213h are communicated and a second orientation in which the support surface intake port 211h and the supply port 213h are communicated, and a valve drive unit 260. When receiving a hot air signal, the control device drives the valve drive unit 260 such that the selector valve 250 is brought into the first orientation, drives the air blower 230, and heats the temperature adjustment member 240.SELECTED DRAWING: Figure 2
【課題】送風機を温風の形成のために用いることと、ヒータの駆動中に送風機が駆動した場合におけるヒータの効率の低下の抑制と、の双方を達成可能なシート温度制御システムを提供する。【解決手段】シート温度制御システムは、シートクッションとシートバック200と制御装置とを備える。シートクッション及びシートバックの少なくとも一方は、本体210と、送風機230と、ヒータ220と、温度調整部材240と、支持面吸気口211hと送風機230との連通を遮断しかつ他部吸気口212hと供給口213hとを連通させる第1姿勢と支持面吸気口211hと供給口213hとを連通させる第2姿勢とに切り替え可能な切替弁250と、弁駆動部260と、を有する。制御装置は、温風信号を受信すると、切替弁250が第1姿勢となるように弁駆動部260を駆動することと、送風機230の駆動と、温度調整部材240の加熱と、を行う。【選択図】図2
