Abstract
Abstract Reinforced body armor and the like is fabricated by securing a plurality of layers of material, having qualities resistant to ballistic penetration, along paths spaced within a selected predetermined range, so as to restrict movement of the fabric layers in lateral and longitudinal directions and to compact the layers in an elastic mass thereby to provide improved resistance to penetration of the material by a ballistic missile and to partially stiffen the material so that shock waves and the force of impact of the missile are distributed over a relatively large area adjacent the point of impact of the missile to reduce back target distortion.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
85 words
A protective material comprising: 1. a plurality of layers of ballistic material, 2. said layers of material being formed of woven continuous filament synthetic yarns, 3. securing means extending along spaced continuous paths interconnecting said layers, 4. said securing means comprising a plurality of continuous uninterrupted stitches at least through a substantial portion of each path with each stitch interconnecting said layers together, 5. said paths being spaced a distance no greater than three-fourths of an inch and no less than one-eight of an inch.
Claim 2
Dependent Claim
85 words
A protective material comprising: 1. a plurality of layers of ballistic material, 2. said layers of material being formed of woven continuous filament synthetic yarns, 3. securing means extending along spaced continuous paths interconnecting said layers, 4. said securing means comprising a plurality of continuous uninterrupted stitches at least through a substantial portion of each path with each stitch interconnecting said layers together, 5. said paths being spaced a distance no greater than three-fourths of an inch and no less than one-eight of an inch.
Claim 3
Dependent Claim
51 words
The material of claim 1 wherein: 6. said plurality of layers include an outer layer, 7. said outer layer being tensioned and flexed by said securing means to provide an angled surface to a missile impacting normally to said material so as to tend to deflect said missile from said material.
Claim 4
Dependent Claim
19 words
The material as defined in claim 2 wherein: 6. the stitches are four to fifteen stitches to an inch.
Claim 5
Dependent Claim
33 words
The material as defined in claim 1 wherein: 6. said paths are disposed along substantially parallel lines; 7. said material being free of securing means extending in a path intersecting said parallel paths.
Claim 6
Dependent Claim
30 words
The material of claim 1 wherein: 6. said plurality of layers of ballistic materials is in the form of a vest having dimensions to cover portions of the wearer's body.
Claim 7
Dependent Claim
18 words
The material as defined in claim 1 wherein said paths of stitches are relatively parallel to each other.
Claim 8
Dependent Claim
29 words
The material as defined in claim 1 wherein the ballistic material is formed of woven nylon fibers and said stitches each comprise a nylon thread joining the layers together.
Claim 9
Dependent Claim
18 words
The material as defined in claim 1 wherein said stitch paths are spaced 3/8 of an inch apart.
Claim 10
Dependent Claim
17 words
The material as defined in claim 1 wherein the stitches are four to eight to the inch.
