ABSTRACT:
A monolithic rail clip, formed from a single piece of material, comprising a plurality of integrated hooks spaced along an angled rail body for use in constructing a seat base. A pair of the rail clips are attached to a pair of opposing members of a frame of the seat base so that the integrated hooks form opposing pairs. A plurality of springs are attached to the hook pairs and stretch between the opposing members to define a resilient structure for supporting a furniture seat. Each rail clip is constructed by forming a plurality of tabs extending from one longitudinal edge the rail body and bending the tabs to form the plurality of hooks. The integral construction of the hooks reduces the assembly time of each rail and seat base. The monolithic construction of the rail clip provides additional structural rigidity to the seat base.
