Abstract
A seat frame for a vehicle seat includes a seat cushion frame that forms a frame for a seating portion of the vehicle seat, and a height adjustment mechanism that is coupled to the seat cushion frame and a rail mechanism of the vehicle seat. The height adjustment mechanism adjusts the height of the seat cushion frame. The height adjustment mechanism includes a sector gear that rotates based on a height adjustment operation, a link that moves the height of the seat cushion frame up and down based on the rotation of the sector gear, and a restriction member that abuts against the sector gear, thereby restricting the movement of the sector gear. At least one of portions of the sector gear and the restriction member that abut against each other has a tapered shape.
