Abstract
Abstract A device for applying a restraining and stabilizing force to a first object, such as an ejection seat, as it moves away from a second object, such as an aircraft. The device itself includes an elongated rendable web means connected between the first and second objects and an element secured to one of the objects and projecting at least partially through the web means to progressively rend the web means as the first object moves away from the second object. The rendering of the web means provides a restraining force which opposes movement of the first object away from the second object and also provides a stabilizing effect on the first object.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
142 words
A device for applying a stabilizing and restraining force to a first object as it moves away from a second object, said device comprising: at least two juxtaposed fabric webs and stitching means normally fastening said webs together; said webs being at least partially slack when said first object is located near said second object; a rigid element secured to one of said objects and projecting between said juxtaposed fabric webs; said element being operative, as said first object moves away from said second object, to progressively contact against and break said stitching means, thereby progressively rending and separating said webs; said breaking of said stitching means by contact and relative movement thereof against said element providing a restraining force which opposed movement of said first object away from said second object and also providing a stabilizing effect on said first object.
Claim 2
Independent Claim
142 words
A device for applying a stabilizing and restraining force to a first object as it moves away from a second object, said device comprising: at least two juxtaposed fabric webs and stitching means normally fastening said webs together; said webs being at least partially slack when said first object is located near said second object; a rigid element secured to one of said objects and projecting between said juxtaposed fabric webs; said element being operative, as said first object moves away from said second object, to progressively contact against and break said stitching means, thereby progressively rending and separating said webs; said breaking of said stitching means by contact and relative movement thereof against said element providing a restraining force which opposed movement of said first object away from said second object and also providing a stabilizing effect on said first object.
Claim 3
Dependent Claim
39 words
A device as defined in claim 1 wherein the quantity and pattern of said stitching means, and the strength of said stitching means can be preselected to thus preselect the amount of restraining force applied to said first object.
Claim 4
Dependent Claim
51 words
A device as defined in claim 1 wherein said stitching means are interrupted at selected portions along said web means to provide a portion where no stitches are broken for a selected interval of time, and during such interval of time, no restraining force will be applied to said first object.
