Abstract
The invention provides a tension structure for constructing a seat back of a seat for an automotive vehicle. Coil springs are provided as tension members which are bridged between respective side portions of a seat back frame and respective vertical bars of a tension assembly in an upper portion and a middle portion. On the contrary, linear wires in which one wire end is entwined and fastened to axes of the vertical bars and another wire end is inserted and fastened to stop rings of the side frame portions 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 by means of the linear wires
