ABSTRACT:
A spring mat assembly for a seat or seat back frame has a pair of relatively widely spaced longitudinal bolster wires across which a plurality of relatively closely spaced transverse stringer wires are connected as by wrapping therearound. The stringer wires extend outwardly beyond each of the bolster wires to form wing edges including a fixed wing at each end of the assembly for attachment to the seat frame, and a free wing on at least one end of the assembly to form with the adjacent fixed wing a split-wing edge on the assembly. The outwardly projecting portions of the stringer wires forming the free wing portion or portions preferably extend at an obtuse angle to their intermediate portions extending between the bolster wires, and they are interconnected at their outermost ends by a longitudinal wire as by being tightly hooked therearound. The stringer wires forming each of the fixed wing portions are either formed with open hook outer ends for attachment to the seat frame or are interconnected at their outer ends by separate additional longitudinal border wires as by being tightly hooked therearound.
