Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
59 words
A method of decelerating evacuees sliding down an inflatable evacuation slide from an elevated egress of an aircraft to a lower surface upon which the aircraft is at rest, comprising the steps of: providing a generally taut fabric sliding surface for evacuees; and rippling the lower portion of the sliding surface to produce alternating transverse ridges and grooves thereacross.
Claim 2
Independent Claim
59 words
A method of decelerating evacuees sliding down an inflatable evacuation slide from an elevated egress of an aircraft to a lower surface upon which the aircraft is at rest, comprising the steps of: providing a generally taut fabric sliding surface for evacuees; and rippling the lower portion of the sliding surface to produce alternating transverse ridges and grooves thereacross.
Claim 3
Dependent Claim
23 words
The method of claim 1 comprising the additional step of coating the lower portion of the sliding surface with a high friction elastomer.
Claim 4
Dependent Claim
30 words
The method of claim 1 wherein the lower portion of the sliding surface is rippled by affixing to the underside thereof a deceleration panel having alternating transverse ridges and grooves.
Claim 5
Dependent Claim
47 words
The method of claim 3 wherein the deceleration panel is produced by the steps of: forming loops in the panel around a cord; stitching the loops to hold the cord therein; and folding the loops over and affixing the loops to the upper surface of the panel.
Claim 6
Dependent Claim
17 words
The method of claim 4 wherein the loops are folded in a direction towards the elevated egress.
Claim 7
Dependent Claim
21 words
The method of claim 4 wherein the folded over loops are affixed to the upper surface of the panel by adhesive.
Claim 8
Dependent Claim
24 words
The method of claim 3 wherein the deceleration panel is affixed to the underside of the lower portion of the sliding surface by adhesive.
Claim 9
Independent Claim
79 words
A method of making a deceleration panel to be affixed to the underside of the lower portion of an inflatable evacuation slide to ripple the sliding side thereof, comprising the steps of: forming a plurality of transverse loops in the panel, each individual loop being formed around a cord; stitching the base of each transverse loop to maintain the cord therein; folding over the individual stitched loops; and affixing the folded over stitched loops to the panel adjacent thereto.
Claim 10
Independent Claim
79 words
A method of making a deceleration panel to be affixed to the underside of the lower portion of an inflatable evacuation slide to ripple the sliding side thereof, comprising the steps of: forming a plurality of transverse loops in the panel, each individual loop being formed around a cord; stitching the base of each transverse loop to maintain the cord therein; folding over the individual stitched loops; and affixing the folded over stitched loops to the panel adjacent thereto.
Claim 11
Dependent Claim
19 words
The method of claim 8 wherein all of the individual stitched loops are folded over in the same direction.
Claim 12
Dependent Claim
84 words
An inflatable slide for evacuation from an elevated egress of an aircraft to a lower surface upon which the aircraft is at rest, comprising: a fluid distensible beam structure extending from the elevated egress to the lower surface; and a floor fabric operably affixed to the fluid distensible beam structure to provide a generally taut sliding surface for evacuees from the elevated egress, the lower portion of floor fabric having alternating transverse ridges and grooves across the sliding surface to decelerate evacuees sliding thereon.
Claim 13
Dependent Claim
84 words
An inflatable slide for evacuation from an elevated egress of an aircraft to a lower surface upon which the aircraft is at rest, comprising: a fluid distensible beam structure extending from the elevated egress to the lower surface; and a floor fabric operably affixed to the fluid distensible beam structure to provide a generally taut sliding surface for evacuees from the elevated egress, the lower portion of floor fabric having alternating transverse ridges and grooves across the sliding surface to decelerate evacuees sliding thereon.
Claim 14
Dependent Claim
50 words
The inflatable evacuation slide of claim 10 wherein a deceleration panel having alternating transverse ridges and grooves is affixed to the underside of the lower portion of the floor fabric to produce the alternating transverse ridges and grooves across the sliding surface of the lower portion of the floor fabric.
Claim 15
Dependent Claim
22 words
The inflatable evacuation slide of claim 10 wherein the lower portion of the sliding surface is coated with a high friction elastomer.
Claim 16
Dependent Claim
49 words
The inflatable evacuation slide of claim 11 wherein the deceleration panel comprises: a fabric panel; a plurality of individual cords; and a plurality of parallel fabric panel loops, individual loops formed around the individual cords, folded over toward the elevated egress end of said fabric panel and affixed thereto.
Claim 17
Dependent Claim
24 words
The inflatable evacuation slide of claim 11 wherein said deceleration panel is affixed to the underside of the floor fabric with a sheet adhesive.
Claim 18
Dependent Claim
64 words
A deceleration panel for affixing to the underside of the lower portion of the sliding surface of an evacuation slide from an elevated egress of an aircraft comprising: a fabric panel; a plurality of individual cords; and a plurality of parallel fabric panel loops, individual loops formed around individual cords, folded over toward the elevated egress end of said fabric panel and affixed thereto.
Claim 19
Dependent Claim
64 words
A deceleration panel for affixing to the underside of the lower portion of the sliding surface of an evacuation slide from an elevated egress of an aircraft comprising: a fabric panel; a plurality of individual cords; and a plurality of parallel fabric panel loops, individual loops formed around individual cords, folded over toward the elevated egress end of said fabric panel and affixed thereto.
Claim 20
Dependent Claim
21 words
The inflatable evacuation slide of claims 13 or 15 wherein said parallel fabric loops are formed around said cords by stitching.
Claim 21
Dependent Claim
23 words
The inflatable evacuation slide of claims 13 or 15 wherein said folded over fabric loops are affixed to said fabric panel by adhesive.
