Abstract
An adjustable arm rest assembly for use on a chair including an arm rest post and an arm rest support surface. According to one aspect of the invention, the support surface is pivotably attached to a top surface of the arm rest post. The support surface includes a front portion and a rear portion and is pivotable about a pivot axis that extends in parallel with the seat back of the chair. A locking element is attached to one of the arm rest post and the support surface. The locking element includes a front portion and a rear portion with the front portion including a first mating element. The front portions of the support surface and locking element are farther from the seat back than the rear portions. A guide member is attached to the other of the arm rest post and the support surface. The guide member is located adjacent the front portion of the locking element and is adapted to receive the first mating element into one of a plurality of second mating elements. The locking element and the guide member are movable with respect to one another so that the support surface may be secured in a selected position relative to the arm rest post.
