Link locking device of seat for vehicle

Abstract

A link locking device of a vehicle seat is configured to prevent a force exerted on a seat belt from causing the rotation of a height link through a buckle. The device includes a sector gear unit rotatably fastened to a cushion frame and fastened to a link connection unit, to which a height link provided in a seat rail is rotatably coupled, to rotate together and a locking unit rotatably coupled to the cushion frame and fastened to a buckle of a seat belt to engage the sector gear unit and block the rotation of the link connection unit when the buckle is pulled. In this configuration, when the buckle is pulled, the locking unit engages the sector gear unit to restrain the link connection unit from rotating to prevent the rotation of the height link, thereby having the effect of preventing the distortion of the seat cushion.
