PROBLEM TO BE SOLVED: To provide an air pressure control device for a vehicle seat which is further excellent in use feeling.SOLUTION: In a seat support adjustment control (step 103) or a massage control (step 105), a control device drives an air pump thereby forcibly feeding air into an airbag provided inside a seat. Further, the control device opens/closes an intake valve provided in a flow channel of air communicating with the airbag. The control device opens an exhaust valve provided on an upstream side of the flow channel with respect to the intake valve after stop of the air pump, and consequently, discharges air, which is encapsulated in the flow channel on an upstream side with respect to the intake valve in the closed state to the outside of the flow channel (step 109, a residual pressure exhaust control).SELECTED DRAWING: Figure 4

    【課題】より使用感に優れた車両シートの空気圧制御装置を提供すること。【解決手段】シートサポート調整制御(ステップ103)又はマッサージ制御(ステップ105)において、制御装置は、空気ポンプを駆動してシートの内側に設けられた空気袋に空気を圧送する。また、制御装置は、その空気袋に連通する空気の流路に設けられた吸気バルブを開閉する。そして、制御装置は、空気ポンプの停止後、吸気バルブよりも流路の上流側に設けられた排気バルブを開放することで、その閉状態にある吸気バルブよりも上流側の流路内に封止された空気を流路外に排出する(ステップ109、残圧排気制御)。【選択図】図4
