Abstract
A lumbar support apparatus installed in a seat back of a vehicular seat has a panel which is movable in front-and-aft direction. A U-shaped spring member is connected at its bent middle portion to the panel and pivotably supported at its opposite ends to a bracket fixed to a seat back frame. A control mechanism for moving the panel in the front-and-aft direction is disposed between the spring member and a pipe frame of the seat back frame. The control mechanism is fixedly in contact with the pipe frame through a stopper member so as to transmit the force from the spring member to the seat back frame in the front-and-aft direction.
