Claims

[Scope of utility model registration request]

A support bracket attached to the seat back frame supports the vertical part formed on one side of the torsion bar so that it can rotate around its axis, and the shaft of the operating lever can also rotate around its horizontal axis. A cam fixed to the operating lever is engaged with the torsion bar, and by rotating the operating lever, a support plate attached to the other side of the torsion bar moves in the front-rear direction of the seat. In the lumbar support of a car seat configured to
A shaft of a second operating lever is inserted into the shaft of the operating lever (first operating lever) so as to be rotatable about the shaft, and the shaft of the second operating lever is inserted into the shaft of the first operating lever. The vertical part of the torsion bar is arranged so as to protrude from the tip of the shaft of the operating lever, and a holding member is screwed into the protruding part of the shaft so as to be movable along the shaft. An automobile seat characterized in that one end of the seat is tiltably supported, and the other end of the vertical part is supported by the support bracket so as to be swingable about a horizontal axis. Lumbar support.
