US 7,017,254 B2 · Rail clip for seat bases

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.

Dependent claims

A method of forming a rail clip for anchoring a plurality of wire springs in a seat base, comprising the steps of:

providing an elongate rail with an angled, constant cross-section having a securing portion for securing the rail to the seat base, and having another extending portion extending at an angle away from the securing portion at the seat base;
forming a plurality of tabs extending from a longitudinal edge of the extending portion of the rail by removing portions of the extending portion to define the tabs, the tabs comprising integral extensions of the extending portion spaced apart along the edge of the rail;
and
bending the tabs to form hooks spaced along the elongate rail and configuring each hook to receive and firmly hold an end of a wire spring.
