To prevent a suspension from being locked out of a design range.SOLUTION: In a suspension device of a vehicle seat, when an upper member is lifted together with a seat body, a pair of lock members of a lock mechanism are relatively displaced. The lock mechanism has an actuator for engaging the pair of lock members, and lifting of an upper member is locked by the engagement. In a state in which a detection part detects that a relative position of the pair of lock members is located out of a lock permissible range set as a range within which the lock is permitted, the actuator is made to be inoperative by the control part.SELECTED DRAWING: Figure 8

    【課題】サスペンションが設計範囲外でロックされることを防止する。【解決手段】車両用シートのサスペンション装置では、シート本体と共にアッパ部材が昇降すると、ロック機構が有する一対のロック部材が相対的に変位する。このロック機構は、一対のロック部材を互いに噛合させるアクチュエータを有しており、当該噛合によりアッパ部材の昇降がロックされる。このロックを許容する範囲として設定されたロック許容範囲外に一対のロック部材の相対位置があることが検知部によって検知されている状態では、制御部によってアクチュエータが作動不能とされる。【選択図】図8
