Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
167 words
A vest having projectile-stopping capabilities comprising inner and outer material cover layers for positioning about a body part of the user, a layer of ballistic material fitted between said layers, said ballistic material being flexible and having projectile-entrapping capabilities upon projectile impact, and including a layer of shock-resistant plate means located adjacent said ballistic material and forming a generally rigid surface when struck by a projectile, said plate means for spreading out and distributing the blunt trauma force of said projectile over a wide area of said vest, the improvement wherein said plate means includes a plurality of juxtaposed plate parts fitted edge to edge, each plate part including an outwardly projecting tab and having a marginal recess opening, said tab of each plate part fitted restrictively into said marginal opening of an adjacent plate part and overlying a portion of said adjacent plate part so as to constitute means for providing a one directional non-flexing interlock with such adjacent plate part to define said rigid surface.
Claim 2
Dependent Claim
167 words
A vest having projectile-stopping capabilities comprising inner and outer material cover layers for positioning about a body part of the user, a layer of ballistic material fitted between said layers, said ballistic material being flexible and having projectile-entrapping capabilities upon projectile impact, and including a layer of shock-resistant plate means located adjacent said ballistic material and forming a generally rigid surface when struck by a projectile, said plate means for spreading out and distributing the blunt trauma force of said projectile over a wide area of said vest, the improvement wherein said plate means includes a plurality of juxtaposed plate parts fitted edge to edge, each plate part including an outwardly projecting tab and having a marginal recess opening, said tab of each plate part fitted restrictively into said marginal opening of an adjacent plate part and overlying a portion of said adjacent plate part so as to constitute means for providing a one directional non-flexing interlock with such adjacent plate part to define said rigid surface.
Claim 3
Dependent Claim
15 words
The vest of claim 1 wherein said plate means is located under said ballistic material.
Claim 4
Dependent Claim
36 words
The vest of claim 2 wherein said vest includes an outer deflector means positioned over said ballistic material said deflector means for turning said projectile so that the projectile contacts said ballistic material at an angle.
Claim 5
Dependent Claim
24 words
The vest of claim 3 wherein said shock resistant plate means is formed of expanded polyethylene and said deflector means is formed of polycarbonate.
Claim 6
Dependent Claim
13 words
The vest of claim 3 wherein said deflector means includes individual raised projections.
Claim 7
Dependent Claim
17 words
The vest of claim 5 wherein said raised projections have angled sides and are pyramidal in shape.
Claim 8
Dependent Claim
14 words
The vest of claim 1 wherein said ballistic material is formed of aramid fibers.
Claim 9
Dependent Claim
82 words
The vest of claim 1 wherein each plate part includes a second said tab and a second said marginal opening, said second tab of at least some of said plate parts fitted restrictively into said second marginal opening of at least some of the other adjacent plate parts and overlying a portion of such last mentioned other adjacent plate parts so as to also constitute said means for providing a one directional non-flexing interlock with said last mentioned other adjacent plate parts.
