Abstract:
1. A seat lifter device for a vehicle, comprising: a pair of right and left base frames; a pair of right and left rear link members; a torque rod for connecting the pair of right and left rear link members for torque transmission; a pair of front right and left link members each including an end being pivoted on a front portion of each of the pair of right and left base frames and forming a parallel link mechanism with the rear link members; a rotation device for relatively rotating the base frames and the rear link members; a lock/unlock device having an engagement/disengagement mechanism for engaging or disengaging a detent member movably supported on a first rotation member fixed to a base frame side, with or from a second rotation member fixed to a rear link member side and a rotating member supported on the base frame side and engaging with or disengaging from the engagement/disengagement mechanism, wherein the lock/unlock device produces a lock condition in which the relative rotation between the first and the second rotation members is restricted by the engagement of the detent member with the second rotation member and an unlock condition in which the relative rotation between the first and the second rotation members is allowed by the disengagement of the detent member from the second rotation member; and an operating member rotatably supported on at least one of said base frames and biased to a neutral position.
