Abstract
Abstract A bulletproof arrangement of woven, knitted or the like fabrics comprised of highly strong fibers comprises at least one continuous material web which forms a plurality of folds which overlap one another like fish-scales. The distances between the edges of the folds are dimensioned smaller than the caliber of a high velocity projectile impacting thereupon, so that the projectile is deflected in the bulletproof arrangement in the sense of a ricochet effect and is thereby kept off an object to be protected.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
188 words
A bulletproof arrangement of woven or knitted fabric material comprised of aromatic polyamide fibers, comprising: (a) at least one continuous web of said fabric material; (b) said web being folded at spaced intervals in a zigzag configuration forming a succession of panels, each panel comprising three layers of said web and having a first fold line between the first and second layers of said web and a second fold line between the second and third layers of said web; (c) said third layer of said web in one panel extending to form the first layer of said web of the next succeeding panel; (d) the distance between the second fold line of one panel and the first fold line of the next succeeding panel being greater than, but less than twice, the distance between the first and second fold lines of said panels such that said panels partially overlap; and (e) the distance between the first fold line of one panel and the second fold line of the panel next succeeding the next succeeding panel being less than the caliber of a projectile impacting upon the bulletproof arrangement.
Claim 2
Dependent Claim
188 words
A bulletproof arrangement of woven or knitted fabric material comprised of aromatic polyamide fibers, comprising: (a) at least one continuous web of said fabric material; (b) said web being folded at spaced intervals in a zigzag configuration forming a succession of panels, each panel comprising three layers of said web and having a first fold line between the first and second layers of said web and a second fold line between the second and third layers of said web; (c) said third layer of said web in one panel extending to form the first layer of said web of the next succeeding panel; (d) the distance between the second fold line of one panel and the first fold line of the next succeeding panel being greater than, but less than twice, the distance between the first and second fold lines of said panels such that said panels partially overlap; and (e) the distance between the first fold line of one panel and the second fold line of the panel next succeeding the next succeeding panel being less than the caliber of a projectile impacting upon the bulletproof arrangement.
