A "U"-shaped bracket having two parallel, flat side plates and a front plate connecting the front ends of the two plates. The rear ends of the parallel plates opposite the front plate are left open. The open end of the U-shaped bracket is sized such that it can be welded onto the cylindrical rod of a seat back frame. Aligned openings are provided in the parallel flat plates of the bracket to accept and rotatably support a cylindrical armrest support rod extending from a pivotable armrest support member. The cylindrical rod includes a laterally extending pin for use in maintaining the armrest support member in a plurality of desired rotational positions with respect to the bracket. The opening in the outside plate of the bracket includes an upwardly and rearwardly extending notch to accept the laterally extending pin of the cylindircal rod. The bracket includes three stops positioned to provide abutments for the laterally extending pin from the cylindrical armrest rod at three usable armrest positions.
