Abstract
Abstract A deceleration panel for the lower section of an aircraft escape slide to control the sliding speed of passengers leaving an aircraft in which longitudinal strips of rubber having a nonskid surface are mounted on strips of fabric supporting material for resisting sliding in the dry condition. The strips of fabric are fastened to a layer of three-dimensional fabric having stiff loops for draining away any water and projecting out of the water to resist sliding in the wet condition. The three-dimensional fabric is mounted on a backing member of fabric supporting material which has a coating of conductive material on the underside as do the strips of fabric supporting materialto conduct static electricity away from the panel.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
69 words
A friction panel providing resistance to sliding in the wet and dry condition comprising a three-dimensional fabric member having upstanding loops for draining water from the surface and presenting a rough surface having a high coefficient of friction in the wet condition and a strip member of friction material mounted over a portion of said fabric member to provide resistance to sliding in the dry condition of the panel.
Claim 2
Dependent Claim
69 words
A friction panel providing resistance to sliding in the wet and dry condition comprising a three-dimensional fabric member having upstanding loops for draining water from the surface and presenting a rough surface having a high coefficient of friction in the wet condition and a strip member of friction material mounted over a portion of said fabric member to provide resistance to sliding in the dry condition of the panel.
Claim 3
Dependent Claim
26 words
A friction panel according to claim 1 wherein said strip member extends longitudinally of the friction panel and is spaced from the edges of said panel.
Claim 4
Dependent Claim
26 words
A friction panel according to claim 2 wherein said friction strip member is fastened to a supporting strip member mounted on top of said fabric member.
Claim 5
Dependent Claim
22 words
A friction panEl according to claim 1 wherein said fabric member is mounted on a backing member of high strength fabric material.
Claim 6
Dependent Claim
76 words
A friction panel according to claim 4 wherein said friction strip member extends longitudinally of said friction panel and is spaced from the edges thereof and mounted on a supporting strip member which is fastened to said fabric member and backing member and wherein said backing member and said supporting strip member have a coating of conductive material on the underside to carry away charges of static electricity generated at the surface of the friction panel.
Claim 7
Dependent Claim
100 words
An aircraft escape slide adapted to be inflated and extend from the aircraft to the ground in an inclined position having an entrance end at the aircraft and an exit end where the slide contacts the ground, a slide lane extending between said exit end and entrance end, and a deceleration panel of high coefficient of friction mounted on said slide lane at said exit end of the slide, said deceleration panel having a three-dimensional fabric member with upstanding loops and longitudinal friction strip members mounted on top of said fabric member and spaced from edges of said fabric member.
Claim 8
Dependent Claim
100 words
An aircraft escape slide adapted to be inflated and extend from the aircraft to the ground in an inclined position having an entrance end at the aircraft and an exit end where the slide contacts the ground, a slide lane extending between said exit end and entrance end, and a deceleration panel of high coefficient of friction mounted on said slide lane at said exit end of the slide, said deceleration panel having a three-dimensional fabric member with upstanding loops and longitudinal friction strip members mounted on top of said fabric member and spaced from edges of said fabric member.
Claim 9
Dependent Claim
25 words
An aircraft escape slide according to claim 6 wherein said friction strip member is mounted on a supporting strip member fastened to said fabric member.
Claim 10
Dependent Claim
66 words
An aircraft escape slide according to claim 7 wherein said supporting strip member has a coating of conductive material on the underside for carrying charges of static electricity from the surface of said panel and said supporting strip members extend beyond the end of the deceleration panel and around said exit end of the escape slide to a position where contact is made with the ground.
Claim 11
Dependent Claim
64 words
An aircraft escape slide according to claim 8 wherein there is a second longitudinal supporting strip member on which a friction strip member is mounted and which is disposed in parallel relationship to said friction strip member so that said supporting strip members cover at least fifty percent of the surface of the friction panel to provide contact with persons sliding over the panel.
