Abstract
Abstract A bullet-proof body-protecting wall structure comprising a thin resilient pressure molded, outer skin of resin impregnated layers of flexible woven fabric with inner and outer surfaces, a non-integrated laminated flexible woven fabric core with inner and outer surfaces arranged with its outer surface adjacent the inner surface of the outer skin to yieldingly support said skin against inward deflection and a soft resilient inner liner with inner and outer surfaces and arranged with its outer surface adjacent the inner surface of the core to yieldingly support said core against inward deflection, said inner surface of the inner lines adapted to be disposed substantially adjacent to a portion of the body to be protected and said outer surface of the outer skin adapted to be disposed substantially normal and opposite to the line and direction of flight of a bullet directed toward said portion of the body.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
145 words
A bullet-proof body-protecting wall structure comprising a thin resilient integrated laminated flexible woven fabric and a resin impregnated outer skin with inner and outer surfaces, a non-integrated laminated flexible woven fabric core with inner and outer surfaces arranged with its outer surface adjacent the inner surface of the outer skin to yieldingly support said skin against inward deflection and a soft resilient inner liner with inner and outer surfaces and arranged with its outer surface adjacent the inner surface of the core to yieldingly support said core against inward deflection, said inner surface of the inner liner adapted to be disposed substantially adjacent to a portion of the body to be protected and said outer surface of the outer skin adapted to be disposed substantially normal and opposite to the line and direction of flight of a bullet directed toward said portion of the body.
Claim 2
Dependent Claim
145 words
A bullet-proof body-protecting wall structure comprising a thin resilient integrated laminated flexible woven fabric and a resin impregnated outer skin with inner and outer surfaces, a non-integrated laminated flexible woven fabric core with inner and outer surfaces arranged with its outer surface adjacent the inner surface of the outer skin to yieldingly support said skin against inward deflection and a soft resilient inner liner with inner and outer surfaces and arranged with its outer surface adjacent the inner surface of the core to yieldingly support said core against inward deflection, said inner surface of the inner liner adapted to be disposed substantially adjacent to a portion of the body to be protected and said outer surface of the outer skin adapted to be disposed substantially normal and opposite to the line and direction of flight of a bullet directed toward said portion of the body.
Claim 3
Dependent Claim
52 words
A wall structure as set forth in claim 1 wherein the fabric is woven of long chain polyester resin fibers having high indexes off shear and tension and a high melting point, said resin impregnating and bonding the fabric of the skin having lower indexes of shear and tension than said fibers.
Claim 4
Dependent Claim
38 words
A wall structure as set forth in claim 1 which further includes an inner skin similar in structure to the outer skin and disposed between the inner surface of the core and the outer surface of the liner.
Claim 5
Dependent Claim
64 words
A wall structure as set forth in claim 1 wherein the outer skin is molded to substantially conform to the configuration of the portion of the body to be protected and to occur in substantially predetermined spaced relationship with said portion of the body, said core and said liner being shaped to conform with the shape of the outer skin and with each other.
Claim 6
Dependent Claim
107 words
A wall structure as set forth in claim 1 wherein the outer skin is molded to substantially conform to the configuration of the portion of the body to be protected and to occur in substantially predetermined spaced relationship with said portion of the body, said core and said liner being shaped to conform with the shape of the outer skin and with each other, wherein the fabric is woven of long chain polyester resin fibers having high indexes of shear and tension and a high melting point, said resin impregnating and bonding the fabric of the skin having lower indexes of shear and tension than said fibers.
Claim 7
Dependent Claim
93 words
A wall structure as set forth in claim 1 wherein the outer skin is molded to substantially conform to the configuration of the portion of the body to be protected and to occur in substantially predetermined spaced relationship with said portion of the body, said core and said liner being shaped to conform with the shape of the outer skin and with each other, said structure includes an inner skin similar in structure to the outer skin and disposed between the inner surface of the core and the outer surface of the liner.
Claim 8
Dependent Claim
81 words
A wall structure as set forth in claim 1 wherein the fabric is woven of long chain polyester resin fibers having high indexes of shear and tension and a high melting point, said resin impregnating and bonding the fabric of the skin having lower indexes of shear and tension than said fibers, said structure includes an inner skin similar in structure to the outer skin and disposed between the inner surface of the core and the outer surface of the liner.
