Disclosed is a fixed-type seat, the seat back of which does not recline, which can take on a normal orientation and a rest orientation (corresponding to a normal reclined orientation). A cushion-material support mechanism which supports a seat cushion material (400) is provided on a cushion frame. Said cushion-material support mechanism has a slide frame (310) that has elongated guide holes (311 and 312) set such that the slide frame can slide diagonally upward/backward and downward/forward with the seat cushion material (400) supported. Since the slide frame slides diagonally downward/forward, although the seat inclination does not change, the seat cushion material (400) moves forward, causing the torso angle of the person sitting in the seat to increase, effectively resulting in a posture similar to that which results when a conventional seat back reclines. |
