Abstract
Abstract A cushion adapted for outdoor use in connection with outdoor furniture or the like including a pair of opposed woven fabric side layers, preferably formed of loosely woven plastic coated filaments, and an interlayer formed of a water impervious material disposed between the side layers, the side layers and interlayer being mutually attached, preferably by heat sealing, along their respective peripherally extending edge regions so as to define a pair of adjacent isolated chambers separated by the interlayer. A filler material is located entirely in one of the chambers such that the interlayer is contiguous with the inner surface of one of the side layers and spaced from the inner surface of the other of the side layers. The outer surface of at least one of the side layers will remain dry or be easily dryable even after either one of the side layers of the cushion is exposed to wet weather conditions.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
198 words
In a furniture cushion for outdoor use of the type including a pair of opposed side layers, each formed of woven fabric material, and attached to each other along their respective peripherally extending regions to define an interior space therebetween and a filler material located substantially throughout said interior space, the improvement comprising: said fabric material is formed of filaments at least the outer surfaces of which comprise thermoplastic material, a thin interlayer formed of water impervious plastic material having a peripherally extending edge region interposed between peripherally extending edge regions of said pair of opposed side layers, said peripherally extending edge regions of said side layers and interlayer being heat sealed to each other to form a continuous seal band extending around the entire periphery of the cushion, said interlayer extending entirely through said interior space to divide the latter into a pair of adjacent isolated chambers separated by said interlayer and wherein said filler material is located entirely in one of said chambers such that said interlayer is contiguous with the inner surface of one of said side layers and spaced from the inner surface of the other of said side layers by said filler material.
Claim 2
Dependent Claim
198 words
In a furniture cushion for outdoor use of the type including a pair of opposed side layers, each formed of woven fabric material, and attached to each other along their respective peripherally extending regions to define an interior space therebetween and a filler material located substantially throughout said interior space, the improvement comprising: said fabric material is formed of filaments at least the outer surfaces of which comprise thermoplastic material, a thin interlayer formed of water impervious plastic material having a peripherally extending edge region interposed between peripherally extending edge regions of said pair of opposed side layers, said peripherally extending edge regions of said side layers and interlayer being heat sealed to each other to form a continuous seal band extending around the entire periphery of the cushion, said interlayer extending entirely through said interior space to divide the latter into a pair of adjacent isolated chambers separated by said interlayer and wherein said filler material is located entirely in one of said chambers such that said interlayer is contiguous with the inner surface of one of said side layers and spaced from the inner surface of the other of said side layers by said filler material.
Claim 3
Dependent Claim
12 words
The combination of claim 1 wherein said filler material is polyurethane foam.
Claim 4
Dependent Claim
13 words
The combination of claim 1 wherein said filler material is polyester fiber batting.
Claim 5
Dependent Claim
30 words
The combination of claim 1 wherein said fabric material comprises filaments woven in a relatively loose weave and wherein each of said filaments comprise thread encapsulated in a thermoplastic material.
Claim 6
Dependent Claim

The combination of claim 4 wherein said thermoplastic material comprises vinyl.
Claim 7
Dependent Claim
57 words
The combination of claim 1 wherein said peripherally extending edge regions of said side layers and interlayer extend outwardly beyond said seal band so that said edge region comprises an inner seal band region and an outer region wherein said side layers and interlayer extend outwardly unsealed to each other and terminate at respective peripherally extending edges.
Claim 8
Dependent Claim
33 words
The combination of claim 6 wherein said peripherally extending edges of said side layers and interlayer are substantially coextensive and are sewn to each other to define a peripherally extending sewn cushion edge.
