ABSTRACT:
A spring assembly for an article of furniture having a seat assembly supported from a chair frame and an actuation mechanism for enabling a leg rest assembly to move between a stowed position and an extended position. The mechanism includes a support shaft, a drive rod spaced apart from the support shaft, and a toggle link coupled to the drive shaft. The spring assembly includes a spring with a first and a second end and adapted to attach to the toggle link at the first end. The spring also includes a member at the second end adapted to slidably engage the support shaft, whereby the spring aligns itself at a position on the support shaft where the length of the spring is at a minimum.
