Abstract
Follow-up performance to respiratory movements is made higher than that of the prior art without obstructing movements of the pelvis of a person. A configuration is adopted that a cushioning member arrangement frame for a seat back 34, 140 and a cushioning member arrangement frame for a seat cushion are displaced according to load fluctuation to a cushioning member for a seat back 40, 150 or a cushioning member for a seat cushion 20. That is, such a configuration is adopted that the cushioning member arrangement frame for a seat back 34, 140 or the cushioning member for a seat cushion 20 not only moves according to load fluctuation but also frames themselves supporting them move via tension structure members spread over the frames (a cushioning member for a seat back and a cushioning member for a seat cushion). Accordingly, when a person lays his/her pelvis at his/her sitting position for deep breathing, the cushioning member arrangement frame for a seat back is displaced to push the vicinity of an upper portion of the cushioning member for a seat back, so that the vicinity of a lower portion of the cushioning member for a seat back is pushed forward to enrich support of the sacrum…
