PCT No. PCT/KR96/00021 Sec. 371 Date Oct. 15, 1996 Sec. 102(e) Date Oct. 15, 1996 PCT Filed Feb. 13, 1996 PCT Pub. No. WO96/25072 PCT Pub. Date Aug. 22, 1996The back of a chair is divided into a waist support (40) and a shoulder support (50) which are pivotally supported by respective support members (27 and 37) so that they can move freely and individually. The waist support (40) and the shoulder support (50) can move back and forth freely and independently against resilient resistance and their inclinations can be adjusted separately and manually. The waist support (40) always supports the waist while keeping close contact therewith and the shoulder support (50) supports the shoulder while keeping close contact therewith. Therefore, even when one uses the chair for a long time, the occupants comfort is assured as no load is applied to the waist. |
