Definitions

  • the present invention relates to a stab-proof protection elementary component.
  • the invention relates to a component adapted to form a stab-proof protection structure comprising at least one flexible base, in particular made of cut resistant fabric, and a reinforcement structure made by means of a plurality of stab-proof protection elementary components.
  • the invention relates in particular, but not exclusively, to a protection structure adapted to make stab-proof vests able to ensure high levels of protection, in particular against the penetration of pointed and bladed weapons such as knives, scalpels or nails, and the following description is made with reference to this field of application with the sole aim of simplifying the description thereof.
  • protective vests against pointed and bladed weapons are increasingly required, generically also referred to as blades, such as knives, scalpels nails, etc.; in particular, said stab-proof protection vests are usually in the form of a vest to be worn under clothing.
  • the stab-proof vests are configured so as to limit the penetration of a pointed or bladed weapon within few millimeters from an exposed surface, so that the weapon cannot come into contact, if not superficially, and preferably in any way, with the body of the vest wearer.
  • the penetration-resistant structures of the blades are configured so as to capture and entangle said blades in order to prevent them from continuing on their way towards the wearer.
  • a stab-proof vest is a reinforced garment, worn both under and over clothing, aimed to protect the wearer's chest, back and hips, offering protection against the penetration of sharp objects, said penetration being limited to few millimeters from an exposed surface onto which sharp objects, generally blades, impact, so as to avoid serious injury to the wearer; said stab-proof vests may also offer protection against small-caliber firearms.
  • stab-proof vests are used not only by police officers, usually under bulletproof vests, but also as single items by paramedics, security guards and bodyguards, just to name a few, the blade penetration trauma injury being statistically the most likely type of assault a public or private security professional could suffer.
  • Stab-blade vests of the known type are made by means of a high performance aramid fiber composite, such as, for instance, Kevlar ® , Twaron ® or PARAX ® by Prosystems, which are para-aramid synthetic fibers capable of making strong and light products, in particular with a very high tensile strength; even polyester may be used to make said vests.
  • aramid fiber composite such as, for instance, Kevlar ® , Twaron ® or PARAX ® by Prosystems, which are para-aramid synthetic fibers capable of making strong and light products, in particular with a very high tensile strength; even polyester may be used to make said vests.
  • Such synthetic fibers are usually tightly woven to create stab-proof vests, the level of protection increasing thanks to the tightly woven fibers that make it extremely difficult for a bladed weapon to penetrate the material, entangling the blade in the fabric and sliding through the woven material.
  • fabrics made by means of tightly woven fibers are usually coated by or coupled with thermoplastic films of polyethylene or polyurethane nature, these films having the function of blocking the fibers so that a blade cannot penetrate between the fibers, moving them with respect to each other and proceed into the fabric, the final weight of the structure obtained being usually 200 to 400 g m/2.
  • said multilayer final structure is more rigid, heavy and with a considerable thickness, which may vary from 6mm to 12mm with density usually ranging from 3.5 kg m/2 to 7 kg m/2. Structures of this type, in addition to being very uncomfortable for a possible wearer, do not usually allow realizing stab-proof vests that can be worn under clothing.
  • the technical problem of the present invention is to provide a stab-proof protection structure having lower thickness and weight, with equal protection, compared to the known solutions, increasing the comfort of personal protection devices realized by means of such a structure, such as the stab-proof vests, improving their overall flexibility and therefore the wearer's comfort, also allowing it to be easily hidden under clothing, always ensuring extended coverage even of irregular surfaces, which is essential in the case of a stab-proof vest to wear, so as to overcome the limitations and drawbacks which still nowadays affect the structures and vests made according to the prior art.
  • the solution idea underlying the present invention is to provide a stab-proof protection structure by means of a plurality of stab-proof elementary components, structurally independent with each other and shaped so as to have mutually complementary perimeter portions, associated with a flexible base of cut resistant fabric in a mosaic shape, said elementary components being able to tilt independently from each other so as to facilitate a folding of the stab-proof protection structure thus obtained.
  • a stab-proof protection elementary component having a plate-like structure of the tile or card type and comprising at least one first face that is substantially plane, one second and opposite face that is substantially plane and parallel to the first face and a profile portion that is substantially orthogonal to said first and second faces, characterized in that said profile portion the multilobed-shaped, the elementary component being made of cut resistant material.
  • the invention comprises the following supplementary and optional features, taken singularly or in combination if necessary.
  • the elementary component may comprise a peripheral section, in turn comprising a plurality of lobes adapted to define the multilobed shape of the profile portion and a central section surrounded by the peripheral section.
  • Said peripheral section may further comprise a plurality of junctions adapted to connect two consecutive lobes of the plurality of lobes, said junctions having a conjugate and complementary shape with respect to the lobes.
  • At least one lobe of the plurality of lobes may have inverse concavity with respect to the other lobes of the plurality of lobes.
  • the junctions may have concavity equal to such at least one lobe of the plurality of lobes.
  • the central section may comprise connection means and the peripheral section may be devoid of said connection means.
  • the elementary component may comprise an adhesive film arranged at the central section to realize the connection means.
  • the peripheral section may comprise lobes and junctions having an arc of a circle shape, the profile portion may be completely radiated since it is only formed by portions of a circle.
  • each of said lobes and junctions may have a shape chosen from: a parabolic arc, a broken line of linear segments, a broken line of curvilinear segments.
  • the elementary component may be made of a plurality of layers of a cut resistant material suitably impregnated with a hardening material adapted to join said layers of fabric.
  • the cut resistant material may be chosen from: an aramid or para-aramid fiber fabric, preferably Kevlar ® , Twaron ® or PARAX ® by Prosystems, or high molecular weight polyethylene, or PBO (i.e. poly benzoxazole).
  • an aramid or para-aramid fiber fabric preferably Kevlar ® , Twaron ® or PARAX ® by Prosystems, or high molecular weight polyethylene, or PBO (i.e. poly benzoxazole).
  • the hardening material may comprise a thermosetting resin chosen from: an epoxy resin, a polyester resin, an acrylic or vinyl ester resin, a polyurethane resin, or a urea resin.
  • the elementary component may comprise a number n ranging between 3 and 8 of layers of cut resistant fabric.
  • the elementary component may have hardness ranging between 70-80 Shore and thickness ranging between 2 mm and 6 mm.
  • the central section may be raised with respect to the peripheral section.
  • a stab-proof protection structure comprising at least one flexible base and a reinforced portion associated with the flexible base, said reinforced portion comprising a plurality of elementary components singularly associated with the flexible base, structurally independent with each other and not linked to each other at profile portions thereof, characterized in that each of said elementary components is made as above indicated.
  • the elementary components may be associated with the flexible base only at the central section thereof.
  • the flexible base may be made of a cut resistant material chosen from: an aramid or para-aramid fiber fabric, preferably Kevlar ® , Twaron ® or PARAX ® by Prosystems, or high molecular weight polyethylene, or PBO (i.e. poly benzoxazole).
  • aramid or para-aramid fiber fabric preferably Kevlar ® , Twaron ® or PARAX ® by Prosystems, or high molecular weight polyethylene, or PBO (i.e. poly benzoxazole).
  • Said stab-proof protection structure may also comprise a plurality of preferential folding lines, positioned in a plurality of free areas formed by peripheral sections of consecutive elementary components, in said free areas the elementary components not being linked to the flexible base, the structure being adapted to cover surfaces or structures having an irregular pattern by folding according to the folding lines.
  • the stab-proof protection structure may have the shape of a stab-proof vest.
  • a stab-proof protection structure 10 comprising a plurality of elementary components 20, independent with each other and contiguous, associated with a flexible base of cut resistant fabric is described.
  • the stab-proof protection structure 10 comprises a reinforced portion 11 associated with a flexible base 12, made of a cut resistant fabric.
  • the flexible base 12 may be made of an aramid or para-aramid fiber fabric, for instance Kevlar ® , Twaron ® or PARAX ® by Prosystems, or by means of high molecular weight polyethylene, or even of PBO (i.e. poly benzoxazole).
  • aramid or para-aramid fiber fabric for instance Kevlar ® , Twaron ® or PARAX ® by Prosystems, or by means of high molecular weight polyethylene, or even of PBO (i.e. poly benzoxazole).
  • the flexible base 12 is suitably associated with the reinforced portion 11, in turn comprising a plurality of elementary components 20.
  • the term "associated" means that the reinforced portion 11 is physically connected to the flexible base 12, for instance connected in any suitable modality, and not necessarily directly connected thereto, but for instance indirectly connected through at least one further interposed layer, such as an adhesive layer.
  • the elementary components 20 are made with complementary and conjugated shapes adapted to interpenetrate like the pieces of a mosaic or a puzzle and to evenly cover the area of the reinforced portion 11, which in this way is finely divided into said elementary components 20.
  • Each elementary component 20 is made of a suitable cut resistant material, meant as a material hindering or even preventing the penetration of a pointed or bladed weapon, in particular a fabric chosen among those that may realize the flexible base 12.
  • the elementary components 20 in the reinforced portion 11 are associated, preferably glued, with the flexible base 12 at a plurality of central sections thereof, side sections of said elementary components being free from being associated, preferably the gluing, with the flexible base 12.
  • the side sections of the plurality of elementary components 20 distributed in the reinforced portion 11 thus define free areas in said reinforced portion 11.
  • said free areas are distributed substantially in all directions and thus suitably allow providing respective folding lines LP1, LP2, LP3 of the stab-proof protection structure 10 where the interference between the elementary components 20 is limited and which may develop in any direction.
  • the elementary components 20 of the reinforced portion 11 of the stab-proof protection structure 10 are distributed so as to evenly cover an area to be protected at the reinforced portion 11 like normal building tiles would cover a floor or wall. Thanks to the particular shape of the elementary components 20 according to the present invention, as it will be clarified in greater detail hereinafter, the same are partially interpenetrated with each other, as pieces of a mosaic or puzzle.
  • said floor or wall actually is a flexible base 12, made of the layer of cut resistant fabric, and the elementary components 20 are capable of following any deformation thereof, for instance in case one wishes to realize stab-proof blade coatings for irregular surfaces.
  • the stab-proof protection structure 10 has the shape of a stab-proof vest, still indicated with reference number 10.
  • the stab-proof vest illustrated in such a figure is in the shape of a vest, the reinforced portion 11 being substantially extended on the entire surface of the vest itself. It is obvious to provide for a different shape, but equally wearable by a user.
  • the reinforced portion 11 is thus realized so as to cover almost the entire chest, the side hips, and the back as well (not shown) of the user wearing the stab-proof vest, also following the shape of the axillary portions, chinstrap, and shoulders.
  • Said reinforced portion 11 actually realizes a total shield for the user wearing the stab-proof vest 10, which may be folded without encountering any resistance at the folding lines, for instance LP1, LP2, LP3, thus being flexible and suitable to be worn in any circumstance, also ensuring enough freedom of movement in any direction to the user wearing it.

  • the peripheral section 22 is quadrilobate-shaped and comprises a first lobe 22A, a second lobe 22B, a third lobe 22C, and a fourth lobe 22D, connected to each other by a first junctions 24ab, a second junction 24bc, a third junction 24cd, and a fourth junction 24da, respectively, said lobes 22A-22D having respective profiles 23a-23d that are complementary and conjugated with the junctions 24ab-24da.
  • the lobes 22A-22D have substantially circular-shaped profiles 23a-23d; equally, the junctions 23ab-23da have a substantially circular pattern. It is noted that, herein and hereinafter, the indication of a circular geometry, as well as the terms “plane”, “parallel” and “orthogonal” are always to be intended in connection to physical elements and not geometrically abstract, and thus must always take into account the tolerances introduced by the transition from a pure mathematical/geometric world to the real world.
  • At least one lobe, in particular the fourth lobe 22D has inverse concavity with respect to the remaining lobes which form the peripheral section 22 of an elementary component 20.

  • each lobe 22A-22D may have a non-circular profile, instead realized by means of a broken line, anyway having a complementary and conjugate pattern with a broken line profile of an adjacent junction 21ab-21da, so as to allow the elementary components 20 to be contiguously placed side by side, with partial interpenetration, in order to form the stab-proof protection structure 10.
  • the lobes 22A-22D are considered as provided with concavity and it is possible to provide for at least one of them an inverse concavity with respect to the others.

  • the linear segments are chosen so as to have a maximum extension of 3mm, so as to properly stop a blade from penetrating between two adjacent elementary components 20.
  • Each elementary component 20 is realized by means of a multi-layer structure comprising a plurality of layers of cut resistant material suitably impregnated with a hardening material adapted to join said layers of fabric.
  • an aramid or para-aramid fiber fabric for instance Kevlar ® , Twaron ® or PARAX ® by Prosystems, or high molecular weight polyethylene, or PBO (i.e. poly benzoxazole), i.e. a fabric suitable for also realizing the flexible base 12, is used.

  • the layers of cut resistant fabric are impregnated by means of a thermosetting resin, for instance an epoxy resin, a polyester resin, an acrylic or vinyl ester resin, a polyurethane resin, or a urea resin.
  • a thermosetting resin for instance an epoxy resin, a polyester resin, an acrylic or vinyl ester resin, a polyurethane resin, or a urea resin.
  • the elementary component 20 comprises n layers of cut resistant fabric, n ranging between 3 and 8, according to the degree of protection desired for the final stab-proof protection structure 10. Said layers of cut resistant fabric are joined by means of the thermosetting resin in a rigid final structure with hardness ranging between 70-80 Shore and thickness ranging between 2 mm and 6 mm.
  • the plate thus obtained is fragmented into the plurality of elementary components 20 having the quadrilobate shape illustrated in Figures 2A-2C , i.e. with a completely radiated profile portion 20S, meaning as only formed by portions of a circle.
  • a blade used against a stab-proof protection structure 10 realized by means a plurality of elementary components 20 associated with the flexible base 12 does not find any straight side and cannot penetrate through the junctions said these elementary components 20 which make up the reinforced portion 11 like a mosaic of the stab-proof protection structure 10.
  • the elementary components 20 are associated with the flexible base 12 just at the central section 21.
  • each elementary component 20 is glued to the flexible base 12 by means of an adhesive film 25 arranged at said central section 21.

It is in particular noted that, at said free areas 13, it is possible to perform the bending of the stab-proof protection structure 10 without the adjacent elementary components 20 interfering with each other.
  • the stab-proof protection structure 10 has the above indicated plurality of preferential folding lines LP1, LP2, LP3, positioned in said free areas 13, said stab-proof protection structure 10 being thus able to adapt to a non-plane surface, for instance when it realizes a stab-proof vest which has to follow the contours of a user wearing it.

Thanks to the so limited overall thickness, besides to the possibility of bending at the folding lines, the stab-proof protection structure 10 may be used to protect shapes with complex geometries, such as for instance the human body, thus realizing a stab-proof vest suitable for being worn even under clothing, for instance substantially in the form of a vest. It is obviously possible to provide for a different form, but equally wearable by a user.
  • the present invention defines stab-proof elementary components, each in the shape of a quadrilobate element comprising at least one central portion and side lobes, in particular four, at least one of said side lobes having concavity facing outwards of the component, i.e. in a direction opposite the central portion.
  • a plurality of elementary components may be associated in a mosaic shape on a flexible base of cut resistant fabric so as not to leave portions of said fabric devoid of said elementary components, thus forming a stab-proof protection structure that may be folded to also cover irregular surfaces, such as for instance anatomic parts of a wearer should said stab-proof protection structure be used to realize a stab-proof vest.
  • the innovative configuration of the elementary components according to the invention thus allows realizing a stab-proof protection structure capable of ensuring an effective protection with optimal levels such as a level KR3/SP3 (Knife/Spike resistant level) of the US NIJ 0115.00 standard in a final structure flexible enough to manage to also cover non-regular surfaces, in particular to realize a stab-proof vest.
  • a level KR3/SP3 Kernife/Spike resistant level
  • the use of the elementary components substantially in the shape of mosaic tiles to form the reinforced portion of the stab-proof protection structure allows minimizing, even eliminating, the portions of the area to be protected which are left uncovered, i.e. devoid of reinforcement elementary components, though ensuring the flexibility and thus the possibility to bend the final structure so obtained.
  • the presence of the lobed peripheral sections of the elementary components forming the reinforced portion comprised in the stab-proof protection structure, peripheral sections which are not associated, in particular glued, with the flexible base, allows defining free areas therein, where the adjacent elementary components do not interfere with each other and the stab-proof fabric which the flexible base is made of is not associated therewith, in particular glued, said free areas extending in any direction so as to allow realizing corresponding folding lines of the stab-proof protection structure so defined.
  • the stab-proof vest according to the present invention is capable of protecting more extended surfaces (in particular different parts of the body) with respect to the known solutions, while maintaining the flexibility of the vest as a whole and thus greater comfort for the wearer, possibly even under clothing.
  • the stab-proof vest could also have different shapes from the vest-like one illustrated and could comprise more sections, distinct from each other, each divided into a plurality of elementary components possibly separated by ballistic fabric portions.
