PROBLEM TO BE SOLVED: To provide a chair in which a backrest and a seat are dynamically moved though in a simple structure. SOLUTION: The seat 1 and the backrest 2 are integrally connected. Support column frames 5 are arranged on both left and right sides of the seat 1, the upper part of the backrest 2 is attached to a back support frame 7 extended from the upper end of the support column 5 to the rear part, and the seat 1 is suspended by a seat support frame extended from the upper end of the support column frame 5 to the lower part. The backrest 2 is provided with a bend allowance part 4, and the part slightly above the bend allowance part 4 is attached to an auxiliary frame 9 in a forward tilting shape in the side face view. When a person leans on the backrest 2, the auxiliary frame 9 is tilted forwards, the back support frame 7 is turned downwards centering on the front end, and the seat support frame 8 is turned to the front centering on the upper end. Since the seat 1 is largely moved forward in linkage with the backward tilting of the backrest 2, comfortableness in a rocking state is improved. COPYRIGHT: (C)2006,JPO&NCIPI
