Abstract:
1. A stackable chair, comprising: a seat assembly including right and left seat members having spaced apart rear portions; a right and left pair of front and rear leg members supporting said seat assembly and joined outboard of respective seat members to facilitate stacking on a like-configured seat assembly; a back support, including spaced apart right and left side support members, said right and left side support members extending downwardly to respective right and left lower ends curved forwardly to be positioned in registry with and spaced apart by right and left gap separations from respective seat member rear portions; and a right and left spring member being separately superposed over respective right and left gap separations, each spring member having a rear portion secured in a substantial surface-to-surface contact relationship with respective right and left back support lower ends, and a front portion secured in a substantial surface-to-surface contact relationship with said right and left seat member rear portions, each spring member being biased to return to a non-flexed position; whereby said back support is reclined when sufficient force is applied against said back support to pivot said spring member rear portions downwardly to a flexed position, said back support being returned to a substantially upright position relative to said seat assembly by each spring member being biased to return to the non-flexed position; wherein said right and left back support lower ends and said right and left seat member rear portions are hollow having generally cubical exterior dimensions and a generally square cross section insert housed inside, said inserts having a convexly shaped end positioned in aligned registry with and spaced apart from respective said back support lower ends and seat member rear portions such that said convexly shaped ends of said seat member rear portion inserts face said convexly shaped ends of said back support lower end inserts, and said convexly shaped ends having convex portions which extend continuously across the entirety of the square cross section insert, whereby upon reclining of said back support, said seat member rear portion inserts engage with said back support lower end inserts and wherein the convexly shaped ends form an abutting relationship that facilitates rubbing against one another.
