Coil springs 3a, 3b, 4a, 4b are provided as tension members which are bridged between respective side portions 11, 12 of a seat back frame 1 and respective vertical bars 20, 21 of a tension assembly 2 in an upper portion and a middle portion. On the contrary, linear wires 5a, 5b in which one wire end is entwined and fastened to axes of the vertical bars 20, 21 and another wire end is inserted and fastened to stop rings 14, 15 of the side frame portions 11, 12 are provided in a lower portion. Accordingly, a sitting attitude is intended to be stabilized by increasing a supporting pressure of a lumbar part applied by the tension assembly 2 by means of the linear wires 5a, 5b.",
