  • Chair having separable back
    Patent number: 5704689
    Abstract: The 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.
