Claims

[Claims for Utility Model Registration] (1) The lower end of the seatback frame is inserted into the inside of the breakover arm, which has a connecting edge on the rear end side and has a substantially U-shaped cross section, and moves forward in the front-rear direction. The breakover arm is rotatably supported, and an arc-shaped forward tilting groove that opens toward the front end along the rotating direction of the seatback frame is formed on the upper end side end surface of the breakover arm, and at least A bearing is inserted in the groove forming part to slide on the inner and outer end surfaces of the breakover arm, and furthermore, fasteners such as bolts and nuts are passed through the bearing and the end surface of the seatback frame through the forward tilting groove, and these are superimposed. A seatback forward tilting device characterized in that a sliding contact portion is tightened with appropriate tightening pressure. (2) The seatback forward tilting device according to claim 1, characterized in that a spacer is interposed between the bearings slidingly in contact with the inner and outer end surfaces of the breakover arm to regulate the minimum distance between the two bearings. (3) The seatback forward tilting device according to claim 1, characterized in that a seatback frame forward tilting stop member is provided protruding from the front end of the breakover arm.
