<P>PROBLEM TO BE SOLVED: To provide a vehicular seat capable of providing high sitting comfort and easily assembling a bent spring material at a low cost. <P>SOLUTION: The bent spring material 6 that elastically supports a seat cushion from the back side is provided. The bent spring material 6 is composed of a wire 7 alternately and continuously having a plurality of linear parts 6a and a plurality of nonlinear parts 6b longitudinally. The bent spring material 6 is configured to arrange a plurality of continuous nonlinear parts 63 in which the plurality of nonlinear parts 6b continue in two rows in parallel by bending a plurality of wire parts 7a continuing to both sides of each of the linear parts 6a positioned at the longitudinal center among the plurality of linear parts 6a of the wire 7 in the longitudinal direction at right angles to be arranged in parallel; and linking an overlapping part 61 with a fixture 62 not to be separated while each of the linear parts 6a of both the wire parts 7a remains opposed to each other are bent and overlapped at right angles. Each of the linear parts 6a positioned to the longitudinal center of the wire 7 is mounted to a shaft 52 and each end of both the continuous nonlinear parts 63 is mounted to a crosslinked frame 51c. <P>COPYRIGHT: (C)2013,JPO&INPIT |
