Abstract
Abstract A structural component for upholstered furniture includes a three-dimensional frame consisting of a plurality of wires which are welded together. A flexible sheet substrate and an upholstery material cover are secured together, with padding held between the substrate and the cover. Clips pierce the substrate and engage the frame such that the upholstery is fastened to the frame.

Claim 7
Dependent Claim
34 words
The structural component of claim 5 in which the folded portion of said substrate is adhesively secured together to maintain the fold, with said clip heads of said clip means held within said fold.
Claim 8
Dependent Claim
34 words
The structural component of claim 1 in which said padding means is a sheet of foam material which is secured to said flexible sheet substrate by pressure-sensitive tape having adhesive on both sides thereof.
Claim 9
Dependent Claim
27 words
The structural component of claim 6 in which the folded portion of said substrate is secured by means of pressure-sensitive tape having adhesive on both sides thereof.
Claim 10
Independent Claim
160 words
The method of making an upholstered furniture component, comprising the steps of: forming a wire frame having multiple wire mats welded together, providing a sheet of flexible material of appropriate shape for covering said wire frame, piercing said sheet at points adjacent its periphery with a plurality of clips, said clips having frame engaging portions extending from said sheet, adhesively bonding padding material to said sheet on the same side of said sheet as said frame engaging portions of said clips, sewing upholstery material to said sheet around the periphery thereof to cover said padding material, while leaving at least a portion of the periphery of said sheet exposed, folding over said periphery of said sheet such that said frame engaging portions extend outwardly on the opposite side thereof from said upholstery material, wrapping said sheet on said frame such that said frame is covered, and engaging a mat of said frame with said clips to form a finished component.
Claim 11
Independent Claim
160 words
The method of making an upholstered furniture component, comprising the steps of: forming a wire frame having multiple wire mats welded together, providing a sheet of flexible material of appropriate shape for covering said wire frame, piercing said sheet at points adjacent its periphery with a plurality of clips, said clips having frame engaging portions extending from said sheet, adhesively bonding padding material to said sheet on the same side of said sheet as said frame engaging portions of said clips, sewing upholstery material to said sheet around the periphery thereof to cover said padding material, while leaving at least a portion of the periphery of said sheet exposed, folding over said periphery of said sheet such that said frame engaging portions extend outwardly on the opposite side thereof from said upholstery material, wrapping said sheet on said frame such that said frame is covered, and engaging a mat of said frame with said clips to form a finished component.
Claim 12
Dependent Claim
42 words
