Abstract:
A chair, comprising:a) a hollow tubular seat frame, having at least two spaced apart open ends; b) a hollow tubular backrest frame, having a pair of spaced apart open ends aligned with and pivotally connected to the open ends of the seat frame at fixed pivot points; c) a limit stop, affixed to each of one of the backrest frame and the seat frame, configured to limit a degree of rotation of the backrest frame relative to the seat frame between an upright position and a maximum backwardly rotated position; and d) a substantially solid elongate spring element, extending from within each open end of the backrest frame into the corresponding open end of the seat frame, configured to bias the backrest frame in the upright position, and to resiliently resist backward rotation of the backrest frame.
