Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
82 words
In an improved seat including a support means for a foamed body contact member, the improvement wherein the surface of the foamed body contact member has cored-out areas, said cored-out areas being positioned to give a geometric pattern of grooves that extend continuously in lengths no more than four inches before the grooves terminate or change direction to give raised portions, each portion being capable of being compressed independent of any other portion for at least 10 percent of its compression deflection.
Claim 2
Dependent Claim
82 words

Claim 3
Dependent Claim
12 words
The improved seat of claim 1 wherein the geometric pattern is hexagonal.
Claim 4
Dependent Claim
23 words
The improved seat of claim 1 wherein the geometric pattern extends across the foamed body contact member on a bias to each edge.
Claim 5
Dependent Claim
28 words
The improved seat of claim 1 wherein the cored-out areas are essentially coextensive with the area covered by a body resting on the seat in the normal position.
Claim 6
Dependent Claim
34 words
The improved seat of claim 1 wherein the depth of the cored-out area varies from the outer edge of the cored-out area to essentially midpoint in at least one direction of the foam member.
Claim 7
Dependent Claim
19 words
The improved seat of claim 5 wherein depth of the cored-out area varies in both longitudinal and transverse directions.
