Definitions

  • the present invention relates to ballistic protective apparel.
  • Soft armor is worn in the form of jackets, vests, etc. which are composed of assemblies of ballistic fabric such as those formed from DuPont Kevlar ® fibers or of Spectra ® ultra high molecular weight polyethylene fibers from Honeywell.
  • the soft armor is often fabricated as flexible panels which are received within pockets or pouches formed in fabric vests or jackets. In more serious threat situations, where higher velocity rifle rounds and fragments must be countered, soft armor has typically been supplemented with hard armor fabricated of rigid plates of ceramic, polymer, or metal.
  • U.S. Pat. No. 6,892,392 discloses soft armor ballistic elements fabricated of multiple layers of ballistic fabric material, for example duPont Kevlar® material, Akzo's Twaron® T-2000 microfilament aramid fiber material, or other conventional ballistic fabric. Fifteen to thirty layers of ballistic fabric are formed together with a 1/16 inch molded plastic stiffening layer which provides some three-dimensional shape.
  • FIGS. 4 and 5 A conventional prior art groin protective ballistic element 10 is shown in FIGS. 4 and 5.
  • the prior art soft armor element 10 is substantially flat, and will be typically fastened to a ballistic vest to hang downwardly to shield the groin of a wearer.
  • the ballistic element 10 is comprised of multiple layers of ballistic fabric which are formed together by heat and pressure to cause a polymer resin to set up and form a single unified element, which may be stitched at the edges, and then enclosed within a fabric bag or pocket.
  • the shape of the prior art element 10 which is suspended from the vest is spaced from the wearer's body, and in the case of an explosion can be displaced or detached from the wearer, thus sacrificing its protective function.
  • a protective element should be closer to the body.
  • Hard armor ballistic protective elements are known, for example in ballistic helmets. Yet a protective element that is too stiff can be uncomfortable to the wearer, especially when encountering obstacles or in situations requiring active movement.
  • the ballistic protective element of the present invention is preferably a compound curved sheet comprised of a stack of multiple layers of ballistic material, for example material of Kevlar ® fibers, or Spectra ® fiber material.
  • the stack may be stitched around the periphery, to obtain the desired level of stiffening, a more or less thick plastic stiffening shape maybe formed together with the layers of ballistic material.
  • the ballistic protective element is preferably somewhat compliant and not so stiff as to excessively interfere with movement of the wearer.
  • the ballistic element may be enclosed within a fabric bag and suspended from a belt, and have a rearwardly opening cup shape to serve to protect the groin of a wearer.
  • the ballistic element may have various compound shapes and be disposed at any desired location on a protective garment, for example to protect a shoulder, a knee, a thigh, an elbow, or an arm.
  • the ballistic protective element can be better positioned to protect the guarded wearer, staying closer to the protected body when exposed to a threat, yet at the same time, the compliant capacity of the element makes it less likely to interfere significantly with the wearer's movements, especially when coming rapidly in contact with some obstacle.
  • FIG. 1 is a perspective view of a ballistic protective groin protective element of the present invention.
  • FIG. 2 is a side elevational view of the groin protective element of FIG. 1.
  • FIG. 3 is an enlarged, fragmentary cross-sectional view of the groin protective element of FIG. 2.
  • FIG. 4 is a perspective view of a prior art ballistic protective groin protective element.
  • FIG. 5 is a side elevational view of the prior art element of FIG. 4.
  • FIG. 6 is a perspective view of a soldier wearing the ballistic protective groin protective element of FIG. 1 in connection with a ballistic protective vest.
  • FIG. 7 is a front perspective view of a shirt having compound curved soft armor ballistic elements received in pockets adjacent the shoulders of the shirt.
  • FIG. 8 is an enlarged cross sectional view of the alternative embodiment protective element of FIG. 7 having a plastic stiffening element.
  • FIGS. 1-8 a compliant body armor ballistic element 20 is shown in FIGS. 1-3.
  • the component 20 will typically be worn together with some type of armored vest 22, as shown in FIG. 6.
  • the component 20 may include a fabric bag 24 which receives a soft armor ballistic element 30, as shown in FIGS. 2 and 3 and which is a thin compound curved concave element, which may be about five-sixteenths inches thick.
  • the enclosing sewn fabric bag 24 protects the ballistic element 30 from wear and soiling.
  • This bag may be a lightweight nylon material.
  • the element 30 is formed as a stack of multiple layers of ballistic material 25, for example material of Kevlar ® fibers, or, for example, layers of material of Spectra ® ultra high molecular weight polyethylene fibers from Honeywell.
  • the stack is formed under heat and pressure with a resin as discussed below, and may be stitched around the periphery, in a quilted pattern, or otherwise, to form a stiffer ballistic element.
  • the element may have a fabric covering adhered thereto, hi an alternative embodiment 100 additional stiffening shape is provided to the ballistic element by adding a stiffening plastic layer 102, as shown in FIG. 8 to the layers of ballistic material.
  • the plastic layer may be about 1/16 to 1/32 inches thick polycarbonate such as General Electric' s Lexan® polycarbonate resin thermoplastic material, and may be adhered or stitched to the ballistic element as disclosed in U.S. Pat. No. 6,892,392.
  • ballistic element is meant an element configured to resist ballistic projectiles or fragments.
  • the ballistic element is formed in a diaphragm press, employing vacuum forming techniques in which a lay up of ballistic material sheets with resin material between the sheets is positioned on an underlying heated mold having the desired compound shape. A vacuum is applied to draw the sheets to the underlying mold, and a rubber sheet is brought down over the lay up to apply even pressure to cause the lay up to conform to the mold under heat and pressure, which causes the resin to set up. hi place of a rubber sheet a metal or rubber match mold could be used, hi this fashion the compound curved ballistic element is formed, avoiding the necessity to employ slits or darts in the ballistic material sheets.
  • the pressure and temperature in the press should be selected such that the formed ballistic element is not a hard shell, but is instead somewhat compliant and resilient. Hence the ballistic element is capable of keeping its shape and being disposed in close proximity to the portion of the wearer's body which it is protecting, but it is nevertheless capable of deforming in response to an obstruction or interference with some obstacle.
  • the groin protective element is preferably attached to a belt 32 and disposed to depend downwardly from the belt to protect the wearer's groin.
  • the element 30 has a generally planar upper margin 34 with a rearwardly opening cup-shaped segment 36 extending downwardly therefrom.
  • the cup-shaped segment 36 tapers as it extends downwardly, and curves upwardly and rearwardly such that is faces downwardly at its lowermost, and is closely spaced from the wearer's groin.
  • a garment of flexible fabric such as a shirt 106 has pockets 108 positioned to overlie a wearer's shoulders, and having flaps 110 which are releasably openable to receive compound curved compliant elements therein.
  • the flaps may be closed with strips of hook and loop fastener, such as VELCRO® fastener manufactured by Velcro Industries B. V.
  • the elements may be reinforced with a molded plastic sheet, as in the element 100 shown in FIG. 8, or the elements may be similar to the element 30 described above without reinforcement.
  • a compliant element which is a developable surface may also be employed where desired.
  • a shirt is illustrated as the garment which receives the ballistic elements, trousers or other another garment may also be employed as a carrier for the ballistic elements.

Abstract

La présente invention porte sur un élément protecteur balistique qui est de préférence une feuille cintrée composite consistant en un empilement de couches multiples de matériau balistique, par exemple un matériau de fibres Kevlar® ou un matériau de fibre Spectra®. L'empilement peut être piqué autour de la périphérie. Pour obtenir davantage de rigidité, une forme rigidifiante en matière plastique plus ou moins épaisse peut être formée conjointement avec les couches de matériau balistique. L'élément protecteur balistique est de préférence quelque peu souple et n'est pas assez rigide pour gêner de manière excessive le mouvement du porteur. L'élément balistique peut être renfermé à l'intérieur d'un sac en tissu et suspendu à une ceinture, et avoir une forme de coupelle s'ouvrant vers l'arrière pour servir à protéger l'aine d'un porteur. L'élément balistique peut avoir diverses formes composites et être disposé à n'importe quel emplacement souhaité sur un vêtement protecteur, par exemple protégeant une épaule, un genou, une cuisse, un coude ou un bras.
