[Scope of Utility Model Registration Claim] A pinion gear provided on one side frame of the seat bag via a brake mechanism, a sector gear that meshes with the pinion gear and rotates, an intermediate portion of which is bent into a crank shape,
a torsion bar to which a lumbar plate is attached, the tip of one end of the torsion bar is locked to the rotating end of the sector gear, and the tip of the other end applies a biasing force to the lumbar plate to press the back of the occupant. The lumbar support is latched to the other side frame side so as to provide a lumbar support.
