ABSTRACT:
A back mounting structure for a chair having a seat and a contoured back extending generally vertically from a rearward curved edge of the seat is achieved by attaching the back and seat with a plurality of angle brackets, each having a horizontally extending leg and a vertically extending leg. The horizontal legs of the angle brackets are attached to the seat and the vertical legs of the angle brackets are attached to the back. The angle brackets more centrally disposed along the joined edges of the back and seat have their horizontal legs attached to the upper surface of the seat. The angle brackets more outwardly disposed along the joined edges have their horizontal legs attached to the underside of the seat. Forces exerted on the seat back tending to force the central portion of the curvilinear joined edges downwardly and the outward portions of the joined edges upwardly are thus counteracted.
