Abstract
Abstract A seat construction comprising a frame including a base and a back. Each of the base and back have a frame with spaced side rails and a spring assembly mounted on the frame. Each spring assembly comprises a plurality of longitudinally extending wires, a plurality of transversely spaced wires having intermediate portions extending between the spaced wires and free ends extending beyond the longitudinally extending wires at an acute angle to the intermediate portion. Each spring assembly further comprises a longitudinal wire along each side edge connecting the free ends of said transversely spaced wires. Each spring assembly is embedded in a body of resilient foam plastic material.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
140 words
In a seat construction, a spring assembly comprising a pair of longitudinally extending wires, a plurality of transversely extending spaced spring wires, portions of said transversely extending spaced spring wires being wound around said longitudinally extending wires to define an intermediate portion extending between the spaced longitudinally extending wires and connected thereto and free ends extending beyond the longitudinally extending wires at an acute angle to the intermediate portion, an additional longitudinally extending wire connecting the free ends of said transversely extending spring wires along each said first-mentioned longitudinally extending wire, a body of foam plastic material in which substantially the entire spring assembly is embedded, a frame comprising spaced side rails, said body and said frame having interengaging portions to provide lateral confinement for said body, said longitudinally extending wires overlying and spaced from portions of said side rails.
Claim 2
Dependent Claim
140 words
In a seat construction, a spring assembly comprising a pair of longitudinally extending wires, a plurality of transversely extending spaced spring wires, portions of said transversely extending spaced spring wires being wound around said longitudinally extending wires to define an intermediate portion extending between the spaced longitudinally extending wires and connected thereto and free ends extending beyond the longitudinally extending wires at an acute angle to the intermediate portion, an additional longitudinally extending wire connecting the free ends of said transversely extending spring wires along each said first-mentioned longitudinally extending wire, a body of foam plastic material in which substantially the entire spring assembly is embedded, a frame comprising spaced side rails, said body and said frame having interengaging portions to provide lateral confinement for said body, said longitudinally extending wires overlying and spaced from portions of said side rails.
Claim 3
Dependent Claim
26 words
The combination set forth in claim 1 wherein said intermediate portions of said spaced wires are substantially adjacent but spaced from one surface of said body.
Claim 4
Dependent Claim
17 words
The combination set forth in claim 1 including a border wire connecting said second-mentioned longitudinally extending wires.
Claim 5
Dependent Claim
24 words
The combination set forth in claim 1 wherein said body includes longitudinally extending grooves in the upper surface thereof overlying said longitudinally extending wires.
Claim 6
Dependent Claim
36 words

Claim 7
Dependent Claim
39 words
The combination set forth in claim 5 including longitudinally extending grooves in said body overlying and spaced from said paIr of longitudinally extending wires, said upholstery material extending into said grooves and means fastening said material to said wires.
Claim 8
Dependent Claim
41 words
The combination set forth in claim 5 including a transverse groove in said body overlying and spaced from an intermediate portion of a transverse wire, said upholstering material extending into said groove, and means fastening said material to said intermediate portion.
Claim 9
Dependent Claim
31 words
The combination set forth in claim 6 wherein said body of foam plastic material includes portions of said body cut away to provide access to said pair of longitudinally extending wires.
Claim 10
Dependent Claim
45 words
The combination set forth in claim 1 wherein said interengaging means between said body and said frame comprises a first extending surface which said first-mentioned longitudinally extending wire overlies and a second surface at an angle thereto, said body having portions thereof engaging said surfaces.
Claim 11
Dependent Claim
13 words
The combination set forth in claim 9 wherein said second surface faces outwardly.
