ABSTRACT:
A one-piece back support for a chair. The support includes a substantially integral backing member having a front side, a back side, and top and bottom edges. The backing member defines, on its front side, a substantially vertical, concave channel. The channel communicates with the bottom edge of the backing member and terminates proximate the center of the backing member. The channel is sized and shaped to receive a "T"-shaped support member so that the backing member is supported by the support member. The backing member, in view of the manner of mounting, can be pivoted about the support member, the channel including laterally extending notches. Such notches project from the main channel portion at its end generally centrally located within the backing member. The "T" portion of the support member is, thereby, received within the channel and notches. The support also includes means to limit the extent to which the backing member can be pivoted with respect to the support member.
