Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
68 words
A traction strip comprising an outer layer of a spun bonded polyester having a high tensile strength in all directions, and a flexible inner layer selected from the group consisting of a cellular hydrophobic and a cellular hydrophillic sponge material bonded to one surface of said outer layer thereby forming a laminate, and means cooperating with said laminate for retaining it on a portion of a wearer''s body.
Claim 2
Dependent Claim
68 words
A traction strip comprising an outer layer of a spun bonded polyester having a high tensile strength in all directions, and a flexible inner layer selected from the group consisting of a cellular hydrophobic and a cellular hydrophillic sponge material bonded to one surface of said outer layer thereby forming a laminate, and means cooperating with said laminate for retaining it on a portion of a wearer''s body.
Claim 3
Dependent Claim
30 words
The strip according to claim 1 wherein the bond between said inner and outer layers comprises a layer of said sponge material which is softened in the presence of heat.
Claim 4
Dependent Claim
20 words
