ABSTRACT:
An office chair is provided having a contoured back assembly comprising a back frame and a suspension fabric. The fabric is attached to the back frame about its periphery wherein the back frame has a three-dimensional contoured shape formed by overlapped frame rings with the fabric being joined thereto. The fabric is secured to the frame by a machine wherein the fabric is first stretched from the outer edge of the fabric and then is clamped by a front frame section in the pre-tensioned or pre-streched condition. The fabric edges are allowed to hang loose and then fixed in the front frame section. Once secured, the fabric is unclamped from the front frame section, and then this sub-assembly is affixed to the rear frame ring to complete the assembly of the back frame.
