Abstract:
1. A self-reclining chair having a variable geometry frame comprising a combination of: a. a U-shaped support-frame with a horizontal member extending along a support surface, said U-shaped support frame providing said chair with transversal stability, said U-shaped support frame having a fixed front-leg ( b. an arched-shaped seat panel comprising a seat portion panel having a hinged back-rest panel, said seat portion panel and said back-rest panel being linked to said upper ends of said front and rear legs, respectively, of said U-shaped support frame, said hinge being located between both said front and rear legs of said U-shaped support frame to provide a lever for said angular displacement of said back-rest panel, a front end of said seat panel having a clamp for angular displacement about a transversal axis located at an upper end of said front-leg, and said back-rest panel having a clamp for angular displacement about a rear transversal axis located at the upper end of said rear-leg of said U-shaped support frame, c. a tension-mechanism linked to said support frame and having incremental adjustment, said tension mechanism configured to pull said seat portion panel downwardly, and to modify the span between said upper ends of said front and rear legs of said U-shaped support frame, and to angularly displace seat panel and said back-rest panel, said tension-mechanism configured to overcome a spring load of said articulated rear-leg of said U-shaped support frame, and d. a control stopper connected to said tension mechanism for automatic synchronized engagement, said control stopper configured to overcome the downward pull of said tension-mechanism, said control stopper being including means to provide incremental adjustments of reclined positions of said chair.
