Abstract

A vehicle seat structure allowing a reduction in the weight of a seat while ensuring cushioning performance. The seat includes a base plate member with an outer frame forming an outer periphery of the seat, and concave portions with seating positions and a seat back position on an inner peripheral side of the outer frame made concave in a direction of a seating load. In addition, the seat includes a fabric member that is provided in a tensioned state in such a manner so as to close open sides of the concave portions for supporting an occupant'"'"'s weight. A first cushion member is provided in positions on the fabric member, at least corresponding to the outer frame.
