PROBLEM TO BE SOLVED: To provide a vehicle seat device which is further excellent in quietness.SOLUTION: A control device as a pressure-sending control part drives an air pump 31, and pressure-sends air to a massage airbag 20 arranged inside a seat. The control device as an expansion/contraction control part performs massage control for expanding and contracting the airbag 20 while driving the air pump 31 by controlling an operation of an intake/exhaust valve 44 which is arranged at a (branch line) of a second flow passage for connecting the air pump 31 and the airbag 20. Then, the control device as a pressure-reduction control part opens an exhaust valve 43 arranged at an upstream side rather than the intake/exhaust valve 44 in a state of contracting the airbag 20 during the execution of the massage control.SELECTED DRAWING: Figure 3
【課題】より静粛性に優れた車両用シート装置を提供する。【解決手段】圧送制御部としての制御装置は、空気ポンプ31を駆動してシートの内側に設けられたマッサージ用の空気袋20に空気を圧送する。また、拡縮制御部としての制御装置は、空気ポンプ31と空気袋20との間を接続する第2流路(の支線)に設けられた吸排気バルブ44の作動を制御することにより空気ポンプ31を駆動したまま空気袋20を拡縮させるマッサージ制御を実行する。そして、減圧制御部としての制御装置は、このマッサージ制御の実行中、空気袋20を収縮させる状態で、その吸排気バルブ44よりも上流側に設けられた排気バルブ43を開放する。【選択図】図3
