ABSTRACT:
The invention is an improved limp material segment coupling assembly. The segment coupling assembly includes a rigid drive member and a segment coupler having a substantially planar lower surface. The lower surface is adapted to frictionally engage a limp material segment. A spring coupler couples the segment coupler to the drive member. The spring coupler includes at least one bent sheet spring. Each bent sheet spring includes a resilient sheet extending between the drive member and the segment coupler. The spring axes of each of the springs are substantially parallel to the planar surface of the segment coupler.
