Abstract
A self-leveling arm assembly is for use with an article of furniture that includes a back rest portion having an arm support. The back rest portion is connected to a seat portion at a first pivot, wherein the backrest portion is pivotable relative to the seat portion between a forward position and a backward position. The assembly includes an arm and at least one linkage member having a first and a second end. The first end is adapted to be pivotably connected to the seat portion, and the second end carries a cross pin for slidable engagement in a path formed in the aim support. The arm includes a pin at one end. The arm is adapted to be connected to the arm support at the one end to define an area of rotation, which includes rotation of the arm about the pin so that upon simultaneous rotation of the back portion and the linkage member about their respective pivots, the arm experiences vertical displacement, but substantially no angular displacement when the backrest is moved between the forward and the backward positions.
