Abstract
Abstract A vehicle seat whose seat back can be collapsed forward in relation to the seat cushion and wherein the projected upper end of a bracket located on the side of the seat cushion is covered by a hinge cover made of synthetic resin to separate the projected end of a bolt from the side of the seat back, so that the surface cover material on the seat back can be prevented from breaking because of the direct contact between the front end of the bolt and the side of the seat back.
