ABSTRACT:
The present assembly relates to a link assembly for a chair. The assembly includes a frame link for connecting to a frame of the chair and a back support link for connecting to a back support of the chair. The frame link and the back support link are pivotably connected in order to facilitate displacement of the back support according to movement of a back frame of the chair. An adjustable pivot point is located on one of the links for selectively adjusting the extent of displacement of the back support relative to the back frame.
