Abstract
A chair comprises:
(i) a seat member having a central portion, a front end and a longitudinally offset rear end;
(ii) a wheeled base;
(iii) a support member extending between said wheeled base and said central portion of said seat member;
(iv) a chair back member pivotally mounted to said seat member for movement between an upright position and a reclined position;
(v) an arm rest member having an button positioned in said arm rest member, said button being movable between a first position and a second position;
(vi) a fluid cylinder transversely offset from said central portion, having actuating member and operatively connected to said chair back member for adjustment of the inclination thereof; and, (vii) a flexible cable having a first end connected to said button and a second end operatively connected to said actuating member whereby, when said button is moved from said first position to said second position, said actuating member is actuated so that the inclination of the chair back member may be adjusted and when said button member is moved from said second position to said first position, the inclination of the chair back member is fixed.
