Seat cushion structure for use in a front seat.

摘要

A seat cushion (14) of a vehicle front seat (10), including a cushion panel (30) and a cushion frame (32), in which the cushion panel (30) and the cushion frame (32) are elastically held together in close proximity to a front edge portion of the cushion panel (30) by means of a torsion spring (64), and are connected together at a rear portion of the cushion panel (30) by means of a pair of rear-linking members (68) which is subjected to an urging force in a tension direction by a pair of tension springs (66). Thus, the seat cushion (14) 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 (14) eliminates pitching because the cushion frame (32) and the cushion panel (30) 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 (30) provides a wider space for an occupant seated in the rear of a vehicle to stretch his legs. <IMAGE>
