ABSTRACT:
A lumbar support device to provided on a seat back frame of a vehicle seat. In this device, a crank-like torsion bar is rotatably secured on the seat back frame via a cramp member having a snap action element, and connected at its one end to a lanced bridge integral with a lumbar plate, without requiring any separate connecting element. Another end of the torsion is abutted on an adjustment cam which is also directly mounted in a cam support bracket, without any separate connecting element, the cam support bracket being fixed on the seat back frame. Additionally, removal prevention elements are integrally provided at connecting points among those torsion bar, cramp member, lumbar plate, cam and cam support bracket, in order to prevent them against removal from one another. Therefore, the number of constituent elements can be reduced and assembling of the lumbar support device may be expedited with great ease.
