Claims

[Claim for Utility Model Registration] A pair of front links and rear links are provided on both sides, with one end pivoted to the seat frame and the other end pivoted to the base plate of the seat, and the height of the seat can be adjusted. In a seat height adjustment mechanism equipped with a height adjustment means, a pair of tilt links are rotatably attached to one end of either the front link or the rear link, and between the seat frames, and one of the tilt links is attached to the seat frame. A drive unit that is rotatably but immovably attached to the seat frame and has an adjuster nut rotatably attached, a tilt handle at the front end, and an adjuster screw screwed into the adjuster nut on the outer circumferential surface. 1. A height adjustment mechanism for a vehicle seat, comprising: a shaft; and an angle adjustment means, the height adjustment means and the angle adjustment means being independently operable.
