<P>PROBLEM TO BE SOLVED: To respond to both of a regular posture and a comfortable posture, allow a user to take a sufficiently relaxed resting posture and provide superior comfort in seating time. <P>SOLUTION: A cushion frame 30 is supported to a rear link plate 41 and a front link plate 42, however, a displacement angle of the rear link plate 41 within a movable range is larger than the displacement angle of the front link plate 42 and an angle formed between the rear link plate 41 and a side frame part 12b of a base frame 10 is defined smaller than that of the front link plate 42. As the rear link plate 41 and the front link plate 42 rotatingly move forward, the seat face angle of the cushion frame 30 is increased. The tilt angle of the back frame 20 itself is unvaried, however, the seat angle of the cushion frame 30 is constituted to be varied following the movement of a person. <P>COPYRIGHT: (C)2008,JPO&INPIT |
