Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
91 words
An improved air management impact absorbing pad comprising: a foam core attached to and enclosed within a generally air-impermeable covering defining a pad having a top side and a bottom side and air management holes in said covering structured and sized in relation to said core for providing controlled transfer of air into and from said pad such that the holes perform a significant impact absorbing function; and wherein the foam of the core is comprised of two or more foam layers with a stretch fabric bonded between the foam layers.
Claim 2
Dependent Claim
91 words
An improved air management impact absorbing pad comprising: a foam core attached to and enclosed within a generally air-impermeable covering defining a pad having a top side and a bottom side and air management holes in said covering structured and sized in relation to said core for providing controlled transfer of air into and from said pad such that the holes perform a significant impact absorbing function; and wherein the foam of the core is comprised of two or more foam layers with a stretch fabric bonded between the foam layers.
Claim 3
Dependent Claim
21 words
The improved impact absorbing pad if claim 1 wherein said air management holes are located on rim sides of said pad.
Claim 4
Dependent Claim
101 words
An improved air management impact absorbing pad, comprising: a foam core attached to and enclosed within a generally air impermeable covering defining a pad having a top side and a bottom side and having air management holes in said covering structured and sized in relation to said core to provide controlled transfer of air into and from said pad such that the holes perform a significant impact absorbing function; and wherein the improvement comprises at least a portion of said covering defining said bottom side being of stretch fabric while said covering substantially defining said top side is of non-stretch fabric.
