Claims

[Claims for Utility Model Registration] In order to incorporate a lumbar support into a seat back made of a thin sheet whose corners are curved over a wide range with a relatively large curvature, a part of the corner of the cushion pad of the seat back is cut out. a protector that is attached to a notch recess formed by the lumbar support, the protector having a mounting base that can be attached to a bracket to which the lumbar support is attached and an opening side of the notch recess that can be closed and that follows a curved corner surface. A lid portion formed in a curved shape is connected to the lid portion via an integral hinge so as to be freely openable and closable, and a locking pawl that is removable from a locking portion formed on the mounting base is formed protruding from the lid portion. The lumbar support protector for a thin sheet is configured such that the opening side of the notch recess can be held by the lid portion along the curved corner surface via the locking pawl.
