ABSTRACT:
A seat cushion of a vehicle front seat, including a cushion panel and a cushion frame, in which the cushion panel and the cushion frame are elastically held together in close proximity to a front edge portion of the cushion panel by means of a torsion spring, and are connected together at a rear portion of the cushion panel by a pair of rear-linking members which is subjected to an urging force in a tension direction by a pair of tension springs. Thus, the seat cushion can be formed with a simplified spring arrangement, and provides easy tuning of these springs because the tension spring exhibits a linear spring characteristic. Furthermore, the seat cushion eliminates pitching because the cushion frame and the cushion panel are connected together at the rear portion thereof behind a hip point of an occupant who is seated in the front seat. Moreover, the seat cushion provides a wider space for an occupant seated in the rear of a vehicle to stretch his legs.
