Abstract
A chair having a self-leveling armrest is disclosed, comprising a seat bottom and a seat back which rotates between a full up position and a full back position. The arm is moveable between an up position and a down position, and is positioned generally parallel with the seat bottom when in the down position. A first link member is pivotably connected to the seat bottom and to a second link member, and the second link member is pivotably connected to the seat back. The arm is pivotable with the seat back, and in the down position the arm moves with the second link member so that the arm remains generally parallel with respect to the seat bottom as the seat back pivots. A pin extends from the arm and is generally parallel with the armrest member. The pin is received by a pin-receiving groove in the second link member.
