Double convolution support system

Abstract

A support system for a seat, comprising a pair of side margins and sets of transverse wires, wherein each set of transverse wires is characterized by a particular convolution pattern. Sets of transverse wires having different convolution patterns are paired in various arrangements to create an expanded traversing region between the transverse wires or an aligned section along the transverse wires. The expanded traversing region allows larger seat components, such as ventilation system components, to be assembled through the expanded traversing regions. The aligned sections of transverse wires may be fastened together and to other seat components to secure the expanded traversing region and the placement of the seat components through the expanded traversing region. In an alternative arrangement, the base sections of the side margins are extended substantially perpendicular to the side margins to form a base support having a particular convolution pattern. The base sections may form an integral, unitary base support or may form separate base supports that are fastened to each other by a clip. Flexcords may be interposed between the base section of the side margins and the base support to provide resilient support.
