Abstract
Abstract Each suspension line of a multi-cell gliding parachute is connected through a lower loop of a primary reinforcing tape folded over on itself. The upper overlying segments of the primary reinforcing tape extend partially across and are stitched to one side of a corresponding fabric rib connected between upper and lower fabric canopies of the parachute. The upper ends of the segments terminate below the upper canopy and are connected to a secondary reinforcing tape also stitched to the rib and spaced from the upper canopy. The upper segments of the primary reinforcing tape and the secondary reinforcing tape form a Y, T or other configuration serving to distribute the load from the suspension line without puckering or otherwise altering the preferred airfoil configuration of the upper and lower canopies.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
173 words
In combination with an inflatable parachute having upper and lower fabric canopies connected by a plurality of airfoil-shaped fabric ribs and a plurality of suspension lines, a structure for attaching each of the suspension lines to a corresponding one of the ribs, comprising: a primary reinforcing tape; means for securing the primary reinforcing tape in overlapping relationship with a corresponding rib; the primary reinforcing tape extending vertically across the rib and having an upper end which terminates below the upper canopy; means for attaching a suspension line to a lower end of the primary reinforcing tape; a secondary reinforcing tape connected to the upper end of the primary reinforcing tape, the secondary reinforcing tape having an upper end which terminates below and is spaced from the upper canopy; and means for securing the secondary reinforcing tape in overlapping relationship with the rib below the upper canopy and spaced therefrom for distributing a load on the suspension line across the rib to thereby inhibit the formation of puckers in the upper canopy when inflated.
Claim 2
Dependent Claim
173 words
In combination with an inflatable parachute having upper and lower fabric canopies connected by a plurality of airfoil-shaped fabric ribs and a plurality of suspension lines, a structure for attaching each of the suspension lines to a corresponding one of the ribs, comprising: a primary reinforcing tape; means for securing the primary reinforcing tape in overlapping relationship with a corresponding rib; the primary reinforcing tape extending vertically across the rib and having an upper end which terminates below the upper canopy; means for attaching a suspension line to a lower end of the primary reinforcing tape; a secondary reinforcing tape connected to the upper end of the primary reinforcing tape, the secondary reinforcing tape having an upper end which terminates below and is spaced from the upper canopy; and means for securing the secondary reinforcing tape in overlapping relationship with the rib below the upper canopy and spaced therefrom for distributing a load on the suspension line across the rib to thereby inhibit the formation of puckers in the upper canopy when inflated.
Claim 3
Dependent Claim
23 words
The combination of claim 1 wherein the primary reinforcing tape and the secondary reinforcing tape are arranged and connected in a T-shaped configuration.
Claim 4
Dependent Claim
23 words
The combination of claim 1 wherein the primary reinforcing tape and the secondary reinforcing tape are arranged and connected in a Y-shaped configuration.
Claim 5
Dependent Claim
19 words
The combination of claim 1, wherein the secondary reinforcing tape is configured in the shape of an inverted triangle.
Claim 6
Dependent Claim
16 words
The combination of claim 1 wherein the means for securing the primary reinforcing tape comprises stitching.
Claim 7
Dependent Claim
16 words
The combination of claim 1 wherein the means for securing the secondary reinforcing tape comprises stitching.
Claim 8
Dependent Claim
21 words
The combination of claim 1 wherein the primary reinforcing tape is folded over on itself to form a lower loop portion.
Claim 9
Dependent Claim
33 words
The combination of claim 7 wheren the means for attaching the suspension line includes a loop portion of the suspension line which passes through the lower loop portion of the primary reinforcing tape.
Claim 10
Dependent Claim
50 words
The combination of claim 1 wherein the primary reinforcing tape extends between a folded over edge of a panel portion of the lower canopy and a folded over lower edge of the rib, and stitching connects the folded over edges of the panel and rib with the primary reinforcing tape.
