Claims

[Claims for Utility Model Registration] 1. In order to move the front or rear part of the seat frame up and down, there is a drive threaded part near the front or rear part of the seat frame, which is parallel to the front and back direction of the seat frame. A movable member that has a drive shaft with an axial direction disposed in the axial direction thereof, and a driven screw portion that is screwed into the drive screw portion, and that moves in the front-rear direction of the seat frame in accordance with the rotation of the drive shaft. a crankshaft whose axial direction is perpendicular to the front-rear direction of the seat frame and which is rotatably attached to the seat frame; a lower end rotatably attached to the movable member; A swinging member whose upper end is fixed to the crankshaft and which swings in the front-rear direction of the seat frame as the movable member moves; A lifter for a seat, comprising: a rotatably attached arm; and means for rotating the drive shaft; and a lifting mechanism disposed near the front or rear end of a seat frame. 2. The seat lifter according to claim 1, wherein the elevating mechanism is disposed at both the front and rear sides of the seat frame. 3. The means for rotating the drive shaft includes: a drive gear attached to the drive shaft; a control gear meshing with the drive gear; and a knob for rotating the control gear. The seat lifter described in item 1 or 2. 4 The drive shafts of the lifting mechanisms disposed near the front and rear portions have a double structure in which one drive shaft is formed in a cylindrical shape and the other drive shaft is inserted into the cylindrical drive shaft. drive shafts, drive gears are disposed close to each drive shaft of this double structure, and a control gear is further provided that meshes with one or both of these drive gears. and rotating one or the other of the drive gears by rotating this control gear,
The seat lifter according to claim 2 or 3, wherein the seat lifter controls the vertical movement of either the front or the rear of the seat, or the front and the rear at the same time. 5. The seat lifter according to claim 4, wherein the control gear is rotated by rotating a knob attached to the control gear.
