Abstract
Abstract First and second members are initially connected together by a frangible means. The first member connects to the pilot parachute suspension lines and the second member, which attaches to a load, connects to control line means. The control line means are connected with a closed loop attached at the periphery of the pilot parachute canopy and are initially slack. When the aerodynamic forces on the canopy cause the first and second members to move relatively to one another, thereby breaking the frangible means, the control line means are pulled taut thus exerting a force on the closed loop which, in turn, reefs the canopy.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
142 words
Means for reefing a pilot parachute comprising: a first member connected with the suspension lines of the pilot parachute; a closed loop attached to the canopy of the pilot parachute along the periphery thereof; a second member adapted for connecting the pilot parachute to a load; control line means connected between said closed loop and said second member; and frangible means initially connecting said first member and said second member together in a manner wherein said control line means are maintained slack; said frangible means being breakable when aerodynamic forces acting on said pilot parachute canopy cause said first and second members to move relatively to each other; said relative movement of said first and second members causing said control line means to pull taut and to exert a force on said closed loop which, in turn, reefs saID pilot parachute canopy.

Claim 3
Dependent Claim
30 words
Means as defined in claim 1 wherein said second member includes a pair of spaced webs and wherein said first member is initially at least partially interposed between said webs.
Claim 4
Dependent Claim
24 words
Means as defined in claim 2 wherein said frangible means connects said pair of webs and thus maintains said first and second members connected.
Claim 5
Dependent Claim
53 words
Means as defined in claim 3 wherein said first member includes an elongated endless loop interposed between said pair of webs and wherein said frangible means is disposed with said endless loop whereby, when aerodynamic forces move said endless loop, at least a portion thereof is brought into contact with said frangible means.
Claim 6
Dependent Claim
21 words
Means as defined in claim 4 wherein said frangible means consist of a row of stitches interconnecting said pair of webs.
Claim 7
Dependent Claim
28 words
Means as defined in claim 1 wherein a series of rings are attached to said canopy along the periphery thereof and wherein closed loop passes through said rings.
