Abstract
Abstract A bulletproof protective plate assembly suitable for use as bulletproof armor. The protective plate assembly includes a plurality of first plates arranged in vertical edge-to-edge relationship. The first plates are formed with contiguous first and second portions, with the second portion disposed at a predetermined angle with respect to the first portion such that the first plates closely conform to the shape of the upper torso of a human being along the vertical plane when the protective plate assembly is applied thereto. One of the lateral edges of the second portion of certain of the first plates is notched or disposed at an obtuse angle with the corresponding contiguous edge of the first portion of the first plate so as to enable the first plates to flex or hinge about the adjoining vertical edges without the edges of the second portions of each plate abutting to thereby closely conform the protective plate assembly to the body of the wearer along the horizontal plane. A plurality of second plates are disposed over the joints between adjoining edges of the first plates. The first and second plates are contained in the desired position within an enclosure that is inserted into a cavity in a conventional bulletproof vest or can be used with an identically formed protective plate assembly and connecting straps to protect both the front and back of the wearer.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
195 words
A protective plate assembly comprising: a plurality of first plates having contiguous first and second portions, said second portion being disposed at a predetermined angle with respect to said first portion such that said first plates closely conform to the shape of the torso of a human being along the vertical plane of the body of the wearer; said first portions of said first plates being disposed in edge-to-edge relationship in a common plane; certain of said second portions of said first plates having at least one lateral edge thereof disposed at an obtuse angle with respect to the contiguous edge of said first portion of said plate to permit said first plates to rotate freely about the adjoining edges of said first portions without interference between the edges of said second portions of said first plates such that said protective plate assembly closely conforms to the shape of the body of the wearer along a horizontal plane; a plurality of second plates disposed in overlapping relationship over the adjoining edges of said first plates; and an enclosure housing said first and second plates and maintaining said first and second plates in the desired position.
Claim 2
Dependent Claim
195 words
A protective plate assembly comprising: a plurality of first plates having contiguous first and second portions, said second portion being disposed at a predetermined angle with respect to said first portion such that said first plates closely conform to the shape of the torso of a human being along the vertical plane of the body of the wearer; said first portions of said first plates being disposed in edge-to-edge relationship in a common plane; certain of said second portions of said first plates having at least one lateral edge thereof disposed at an obtuse angle with respect to the contiguous edge of said first portion of said plate to permit said first plates to rotate freely about the adjoining edges of said first portions without interference between the edges of said second portions of said first plates such that said protective plate assembly closely conforms to the shape of the body of the wearer along a horizontal plane; a plurality of second plates disposed in overlapping relationship over the adjoining edges of said first plates; and an enclosure housing said first and second plates and maintaining said first and second plates in the desired position.
Claim 3
Dependent Claim
33 words
The protective plate assembly of claim 1 further including means for flexibly interconnecting the first plates in a unitary assembly such that said first plates are free to rotate about their adjoining edges.
