Abstract
Abstract A bullet-proof protective armor formed of a flexible support sheet having a large number of equal size, approximately square, flat metal plates secured upon the opposite faces of the sheet. The plates on each sheet face are arranged in a checkerboard pattern, that is, corner to corner, with a plate size space between each group of adjacent plates. The checkerboard pattern of the plates on one face of the sheet are reversely arranged relative to the pattern on the opposite face of the sheet. Thus, the plates on one face of the sheet are aligned with and overlap the spaces formed between the plates on the opposite face of the sheet. Flexible cover sheets are adhesively secured to the exposed faces and edges of the plates and the exposed portions of the support sheets to secure the plates to the support sheets and permit flexing of the armor.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
183 words
A protective Armor comprising a flexible support sheet and a plurality of approximately equal size, flat, relatively small metal plates arranged upon the opposite faces of the sheet; the plates being arranged in a checkerboard pattern upon each of the opposite faces of the sheet, each checkerboard pattern including adjacent metal plates in a corner-to-corner relationship with open spaces between edges of adjacent plates, with the pattern of the plates on one face of the sheet being reversed to the pattern of the plates on the opposite face of the sheet; said plates on one sheet face filling the spaces on the opposite sheet face with the edges of the plates on one sheet face aligned with the edges of the plates on the opposite sheet face without the plates on one sheet face overlapping onto the plates on said opposite sheet face; and means for securing each of the plates to the support sheet, wherein the armor may be bent and flexed along the edges of each of the plates and each of the plates is movable relative to the other plates.
Claim 2
Dependent Claim
