Abstract
A ratchet-type lever mechanism for seat lifter, which comprises a brake unit whose shaft is connected with a mechanism of the seat lifter, two ratchet gear wheels provided about the shaft of brake unit, a shaft rotatable in a spaced-apart relation with the brake unit shaft, an operating lever connected with the shaft, and a sector ratchet gear element provided between the operating lever and two ratchet gear wheels. The sector ratchet gear element is so arranged in the lever mechanism to enable a user to rotate the operating lever in usual way without confusion about direction of rotation of the lever to cause upward and downward motions of the seat lifter. The sector ratchet gear element may be of an outwardly-toothed type having two outwardly toothed arcuate gear teeth and two sector gear portions, or may be of an inwardly-toothed type having two inwardly toothed arcuate gear teeth.
