  "textContent": "A seat structure comprises an arm in the rear of a seat cushion; supporting frame supported by arm; front frame in the front of seat cushion; cushioning mechanism spread over between supporting frame and the front frame, and strained by an elastic force of the torsion bar; and standard position setting mechanism. A haunch supporting portion of the cushioning mechanism is lifted upward by forcing front edge of front frame in downward direction. A seat structure comprises an arm (16) arranged in the rear of a seat cushion (10) and enforced in a direction of falling backwards with a torsion bar (15) in a normal state; supporting frame (12) supported by arm and arranged along a width direction in the rear of the seat cushion; front frame (13) in the front of seat cushion having a predetermined width in a longitudinal direction of the seat cushion, and its front edge being movably supported in a vertical direction; cushioning mechanism (20) spread over between supporting frame and the front frame, and strained by an elastic force of the torsion bar; and standard position setting mechanism for setting an upward moving position of the front edge of the front frame when a person is seated on the cushioning mechanism in a standard posture. The front edge of the front frame is moved more in an upward direction than a standard position when a load for depressing any portion of the cushioning mechanism is applied compared with the time of being seated on the cushioning mechanism in the standard posture. A haunch supporting portion of the cushioning mechanism is lifted upward by forcing front edge of front frame more in a downward direction than the standard position.",
