Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
63 words
A polyurethane foam body support member having a mesh reinforcing member positioned at a predetermined depth below the top surface thereof and the foam has a density of less than 2.8 and less than 2.2 when the body support member is, respectively, a mattress, or a seat and a seat back, said mesh reinforcing member stopping before reaching any edge of the foam.
Claim 2
Dependent Claim
63 words
A polyurethane foam body support member having a mesh reinforcing member positioned at a predetermined depth below the top surface thereof and the foam has a density of less than 2.8 and less than 2.2 when the body support member is, respectively, a mattress, or a seat and a seat back, said mesh reinforcing member stopping before reaching any edge of the foam.
Claim 3
Dependent Claim
17 words
The body support member of claim 1 wherein the reinforcing member is of metallic or wire construction.
Claim 4
Dependent Claim
72 words
The body support member of claim 1 wherein a surface of the body is divided into a decorative segment by cored-out areas, said cored-out areas being positioned to give a geometric pattern of not more than 9.8 centimeters in length before the grooves terminate or change directions 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 5
Dependent Claim
13 words
The body support member of claim 3 wherein the geometric pattern is hexagonal.
Claim 6
Dependent Claim
34 words
The foam mattress core of claim 3 wherein the cored-out areas in the crown extend no closer than 2.54 centimeters of each edge of the core to leave an uncored strip adjacent each edge.
Claim 7
Dependent Claim
24 words
The foam mattress core of claim 3 wherein the geometric pattern is formed by curved members to leave raised portions inside said curved members.
Claim 8
Dependent Claim
21 words
The foam mattress core of claim 3 wherein the geometric pattern extends across the core on a bias to each edge.
Claim 9
Dependent Claim
17 words
The body support member of claim 1 wherein the reinforcing member is laminated between layers of foam.
Claim 10
Dependent Claim
17 words
The member of claim 1 wherein the reinforcing member is positioned 3.1±1.0 centimeters below the top surface.
Claim 11
Dependent Claim
36 words
The member of claim 1 wherein at least part of the foam above the reinforcing member has a density of at least about 0.5 density units greater than the density of the foam beneath said member.
