ABSTRACT:
A first cushion receiving member of a seat cushion and a second cushion receiving member of a seat back are turnably connected to each other by a connecting member. The first cushion receiving member is turnably supported at its front end on a front frame of a first framework. The second cushion receiving member is supported on a second framework, through a spring fixed at its upper portion at at least two points and at its lower portion to the second framework and through an elastic fabric having a periphery fixed to the second framework. Thus, the first and second cushion receiving members can be prevented from being oscillated laterally, and the vibration caused by the expansion and contraction of the spring can be dampened by the elastic fabric. As a result, it is possible to permit the longitudinal and vertical movement of the first and second cushion receiving members for supporting the cushion members of the seat and to restrict the lateral movement of the cushion receiving members, and to thereby prevent uncomfortable lateral oscillation of an occupant's body so as to improve sitting comfort.
