Definitions

  • the present invention relates to a bulletproof protection elementary component.
  • the invention relates to a component adapted to form a bulletproof protection structure comprising at least one flexible base, in particular made of ballistic fabric, and a reinforcing structure made by at least one ballistic panel associated with the flexible base and made in turn by a plurality of bulletproof protection elementary components.
  • the invention relates, particularly, but not exclusively, to a protection structure adapted to realize bulletproof vests capable of ensuring high protection levels, in particular greater than IIIa level according to the US NIJ regulation, and the following description is made with reference to this application field with the only purpose of simplifying the exposition.
  • the number of the overlapping layers determines the protection ability of the structure as a whole, classified in protection classes NIJ (United States) or SK (Germany), for instance.
  • These structures are generally made of high tenacity fibers, such as for instance the aramid fibers, which have a high mechanical tensile strength and high heat and flame resistance, which make them particularly suitable for use in bulletproof vests, the high resistance being in this case used to absorb the kinetic energy of the bullets through permanent deformation, thus minimizing the effects on the user wearing the vest.
  • the fiber structures can provide effective protection against short-weapon bullets and limited to automatic weapons up to 7.65 caliber or 9 Parabellum, corresponding to 357 and 44 Magnum pistols and at speeds up to about 500m/s. This corresponds to IIIa protection level according to the US NIJ regulation.
  • these ballistic panels may be made of metal materials or more often of the so-called ballistic ceramic, namely a high strength alumina oxide that may precisely fragment the bullets, so as to divide them into splinters and usually have fairly large thicknesses, for instance between 5 and 12 mm, preferably between 7 and 10 mm.
  • a bulletproof protection structure for calibers greater than 357 and 44 Magnum, namely greater than IIIa level of the US NIJ regulation, made according to the prior art is schematically illustrated in Figure 1 , globally indicated with reference number 10.
  • a bulletproof protection structure 10 may be for instance used for shoring vehicles and tanks.
  • the bulletproof protection structure 10 in the case illustrated just by way of example, has a substantially rectangular shape and comprises a fiber base 11, made for instance of high-tenacity fibers, for instance interwoven, also referred to as ballistic fabric.
  • Said bulletproof protection structure 10 further comprises a plurality of ballistic panels 12, associated with the fiber base 11, for instance by gluing.
  • the ballistic panels 12 may be made of ballistic ceramic.
  • the ballistic panels 12 may be suitably spaced apart so as to define, between two contiguous panels, at least one portion 13 of the fiber base 11 free from said ballistic panels and thus allow folding the bulletproof protection structure 10 at folding lines indicated with reference number 14.
  • the bulletproof protection structure 10 illustrated in Figure 1 can thus cover a prismatic-shaped object, in particular with a squared base since the ballistic panels 12 illustrated in the figure are of equal size.
  • the bulletproof protection structure 10 with ballistic panels 12 of different size, in particular suitable for following the shapes of the objects to be covered and protected, as evenly as possible.
  • This makes the protection of non-regular surfaces complicated and practically impossible in case of rounded shapes, such as for instance cylindrical towers, actually imposing squared and sharp shapes.
  • the portions 13 without ballistic panels 12 are less protected, in particular penetrable by bullets of caliber greater than 357 and 44 Magnum or greater than IIIa level of the US NIJ regulation. In these portions 13, which may also have great dimensions, the bulletproof protection is indeed only ensured by the fiber base 11.
  • the bulletproof vest is a garment, generally a vest-or-jacket-style garment, used by armies and law enforcement, which is useful to protect a wearer from gunshots or splinters from explosive fragmentation (in this case, being more commonly indicated as "flak jacket”), since it stops the bullet or splinters therein.
  • This kind of garment is also used by security guards, for instance in service at the banks, or for the transport of valuables.
  • a bulletproof vest is made of an outer container suitably of ballistic fabric, and of one or more internal ballistic panels, for instance of ballistic ceramic.
  • ballistic panels are particularly used as shields and thus are usually placed in front of the the person's chest, thorax and in the rear part of the back and, in some cases, in the lower part, on the waistband of the lateral sides, on the right and on the left, so as to ensure protection to the vital organs of the user wearing the vest.
  • these ballistic panels are an obstacle to the dynamics of a moving human body, limiting the freedom of the bulletproof vest wearer.
  • the user wearing the bulletproof vest is hindered for instance in the bust movements, or even in the side movements, forward and backward, the use of the reinforcing ballistic panels introducing in the garments an extreme stiffness and an additional weight that limit the comfort of the wearer, besides ensuring effective protection just to a surface that is substantially limited to the areas of vital organs, such as for instance the heart, thanks at least to one ballistic panel placed at the chest of the user wearing the vest.
  • a bulletproof protection structure which is made by means of a ballistic panel finely divided into a plurality of contiguous elements that are structurally independent and associated with a fabric portion, having a flexibility degree enough to ensure an extended coverage even of non-regular surfaces, like in the case of a bulletproof vest to be worn, meanwhile increasing the protection level.
  • a bulletproof protection structure is described for instance in Italian patent application No. IT 102015000019024 filed on 28/01/2015 to the same applicant and schematically illustrated in Figure 2 .
  • the bulletproof protection structure 20 comprises a fabric portion, particularly made by high-tenacity fibers, for instance interwoven, namely of ballistic fabric.
  • the portion of ballistic fabric is substantially a flexible base 21 of the bulletproof protection structure 20.
  • the ballistic fabric may comprise high molecular weight polyethylene.
  • the bulletproof protection structure 20 is further provided with a ballistic panel 22, associated with the flexible base 21, for instance by gluing or by providing a containing liner and suitable pockets made therein.
  • the ballistic panel 22 thus realizes a reinforcing structure of the flexible base 21 made of ballistic fabric of the bulletproof protection structure 20.
  • the ballistic panel 22 is in particular finely divided into a plurality of elementary components 23 having a surface extension that is less than that of the ballistic panel 22 and being in a number sufficient to realize a coverage of an area to be protected AP by means of said ballistic panel 22.
  • elementary components 23 are structurally independent and singularly associated with the flexible base 21 of ballistic fabric, so as to be contiguous and to minimize, at the limit to cancel, the portions of the area to be protected AP that are left uncovered, namely without elementary components 23.
  • the elementary components 23 are substantially made like tiles, in the shape of a flattened parallelepiped, with two faces, a bottom face and a top face respectively, of greater extension, and a side portion that runs along the entire contour of the elementary component 23 and has a height Hz selected based on the protection degree required to the ballistic panel 22. More particularly, referring to Figure 2A , these elementary components 23 are associated at one of said faces of greater extension, such as the bottom face Fb, for instance by gluing with thermoplastic films, whereas the sides 23s are substantially without retaining means to the adjacent elementary components. This allows a movement of said elementary components 23 in a plane Z that is orthogonal to the plane defined by the ballistic panel 22, in practice orthogonal to the sheet whereon the bulletproof protection structure 20 is illustrated.
  • this floor or wall is actually a flexible substrate, made by the flexible base 21 of ballistic fabric, and the elementary components 23 in the form of tiles can follow the possible deformations thereof, for instance in case one wishes to realize bulletproof coverings for non-regular surfaces.
  • the ballistic panel 22 finely divided into the elementary components 23 and associated with the flexible base 21 of ballistic fabric, and thus the bulletproof protection structure 20 thus formed, are flexible structures capable of covering surfaces or structures with irregular trend.
  • the elementary components 23 preferably have a hexagonal shape, so as to obtain a bulletproof protection structure 20 that can be easily folded at substantially vertical or horizontal folding lines, using the local reference of the figure (in which just a vertical folding line 24a is indicated) and according to substantially oblique folding lines, like line 24c, as indicated in Figure 2 .
  • said known solution has the drawback of having an interference area between adjacent elementary components or tiles under folding conditions, precisely at a folding line.
  • an interference zone Zi exists, which extends around to each folding line, for instance at the vertical folding line 25a indicated in Figure 3A still with reference to a bulletproof protection structure 20 comprising a ballistic panel 22 that is finely divided into the elementary components 23 and associated with the flexible base 21 of ballistic fabric, the elementary components 23 being in particular glued to the flexible base 21 of ballistic fabric at the bottom face Fb thereof, as indicated in Figure 3B .
  • each elementary component 23 thus completely rests on and is linked to the ballistic fabric that forms the flexible base 21 of the bulletproof protection structure 20.
  • the "real" fold line 24a has a broken or polygonal line trend that follows the edges of the single components or tiles based on an "ideal" fold line 25a which should follow the underlying fibers of ballistic fabric forming the flexible base, said "ideal" fold line 25a being rectilinear.
  • the interference zone Zi is illustrated for a vertical "real" fold line 24a, a quite similar situation also occurs for a transverse fold line24c, which still has a broken or polygonal line trend that follows the edges of the single components or tiles based on a rectilinear "ideal" fold line 25c.
  • the interference zone Zi substantially comprises portions of the top face Fa of the elementary components on the fold line 25a; in particular, in said interference zone Zi, each elementary component comes into conflict with an adjacent component along the "ideal" fold line 25a, thus preventing a correct fold of the bulletproof protection structure 20 comprising the ballistic panel 22 formed by the elementary components 23 and thus its precise adaptation to an irregularly shaped surface to be protected.
  • the interference zone Zi has a transverse dimension Hz equal to 9.2 mm.
  • a real fold line 24 has a sinusoidal trend around to a rectilinear ideal fold line 25, defining, as previously, an interference zone Zi between adjacent elementary components 23 along said fold lines, as indicated in Figure 4A still with reference to a bulletproof protection structure 20 comprising a ballistic panel 22 divided into the elementary components 23 having circular cross section with diameter D and associated with the flexible base 21 of ballistic fabric, the elementary components 23 being still glued to the flexible base 21 at the bottom face Fb thereof, as indicated in Figure 4B , and the top face Fa thereof may also be dome-shaped, as illustrated in the figure.
  • the interference zone Zi has a transverse dimension Hz equal to 4 mm.
  • the bulletproof protection structures 20, comprising a ballistic panel 22 divided into the elementary components 23, singularly glued to a flexible base 21 of ballistic fabric have a limited flexibility degree linked to the elongation properties of the fiber used to make the flexible base and to the type of adhesive used to link the elementary components 23 thereto.
  • the high tenacity fibers used to realize such bulletproof protection structures 20 generally have an elongation equal to 3-4%, which is analogous to the elongation values provided by the adhesive films traditionally used in this field, we can immediately conclude that the structures thus obtained cannot be adapted to particularly irregular shapes, such as those of a human body, and therefore are not suitable for making bulletproof vests.
  • the technical problem of the present invention is to provide a bulletproof protection structure having a sufficient flexibility degree to also ensure an extended coverage for non-regular surfaces, like in the case of a bulletproof vest to be worn, meanwhile minimizing the exposed ballistic fabric surfaces, thus increasing the protection level conferred by said vest, so as to overcome the limitations and drawbacks which nowadays still affect the structures and vests realized according to the prior art.
  • the solution idea underlying the present invention is to make a bulletproof protection structure by means of a plurality of contiguous and independent elementary components which are shaped so as to have at least one raised section adapted to delimit the connection surface, in particular by gluing, between said elementary components and a flexible base of ballistic fabric of the protection structure, thus eliminating interferences between contiguous elementary components on occasion of a folding of the structure itself.

  • the invention comprises the following additional and optional features, taken singularly or in combination if necessary.
  • the bulletproof protection elementary component of the tile type may comprise a free surface defined in the first face as a remaining area around to the raised section.
  • said raised section may be concentric with the first face of the body.

  • connection means 58 in particular adhesive layers 58A, only at the raised sections 51 of the tile-shaped elementary components 50 allows the maximum freedom degree for the bulletproof vest 60' that comprises the flexible base 56 of ballistic fabric and the ballistic panel 55 realized by said tile-shaped elementary components 50, in particular, thus ensuring the correct covering of the user's body wearing it, meanwhile minimizing the impediments to movement.
  • the bulletproof vest 60' could also comprise a lower protection portion (not illustrated), in the form for instance of a strip still provided with reinforcing elementary components that can pass between the user's legs wearing it.
  • the innovative configuration of the elementary components according to the invention allows realizing a ballistic panel and a bulletproof protection structure comprising it which can ensure an effective bulletproof protection for calibers greater than 357 and 44 Magnum, namely greater than IIIa level of the US NIJ regulation, in a finale structure that is flexible enough to also cover non-regular surfaces.
  • a bulletproof protection structure of the illustrated type may cover the hood of a vehicle such as a Jeep®.
  • the bulletproof protection structure according to the present invention advantageously allows increasing the protection level until reaching calibers such as AK47 and SS109 NATO; furthermore, by increasing the thicknesses both of the portion of ballistic fabric and of the elementary components into which the ballistic panel is finely divided, it is possible to reach more important calibers, such as Dragunov or SVD rifle (acronym from the Russian: “Snayperskaya Vintovka Dragunova”) M2AP NATO.
  • a bulletproof protection structure such as a bulletproof vest, which remains flexible, but ensures a bulletproof protection for calibers greater than 357 and 44 Magnum, namely greater than IIIa level of the US NIJ regulation.
  • the presence of the raised sections provided in all of the elementary components forming the ballistic panel comprised in a bulletproof protection structure allows defining free areas in said ballistic panel where the adjacent elementary components do not interfere with each other and the ballistic fabric of the flexible base is not glued thereto; more particularly, said free areas extend in any direction, since corresponding folding lines of the ballistic panel may be defined therein.
  • the bulletproof vest according to the present invention can protect more extended surfaces (in particular different parts of the body) with respect to the known solutions, maintaining the flexibility of the vest as a whole and thus a greater comfort for a wearer.
  • the bulletproof vest could also have different shapes than the vest one illustrated and could comprise more ballistic panels, each divided into a plurality di elementary components in the case separated by portions of ballistic fabric.
