Abstract
An operation mechanism of a lifter for an automotive seat, including a drive mechanism, a drive shaft operatively connected with the drive mechanism, a gear fixed on the drive shaft, a pair of first and second latch pawls engageable with the gear, and a switch-over cam for selectively disengaging one of the two latch pawls from the gear, with the other of them remaining in engagement with the gear, which forms a ratchet structure. Such actuation of the switch-over cam is effected by drawing out or retracting the handle of lever provided with the mechanism. Thus, the rotational direction of the gear is set by drawing out or retracting the handle, which causes raising or lowering of the seat through the drive mechanism.
