Abstract

Armour, in particular body armour for female wearers is made of multiple layers (30) of penetration-resistant material for example made of polyaramid fibers, specially shaped to fit over a shaped area to be protected, e.g. the bust of a female wearer. The armour's shaped part is held in shape by a series of darts (37) in successive layers (30) of the material. Each dart in a material layer comprises a generally V-shaped section (35) whose edges (37) arc joined to form the dart. The V-shaped section (35) of the material is folded on itself to form a pleat (40) which is folded over to one side of the dart (37) to form an added thickness overlaying or underlying an adjacent part of the material (30). The darts (37) are angularly offset from one another with the pleats (40) oriented in directions so that the added thickness is distributed substantially evenly, thereby avoiding bulges or stiffness and improving the wearing comfort.

Description

The invention relates to protective clothing made of a multi-layered material that has resistance to penetration, and to a large extent to a body armor containing a part of a special shape that adheres to the curved surfaces of the body, such as a female bust, also this invention relates to a method of manufacturing this clothing .

Technical level

The use of high tensile strength fibers such as polyaramid fibers in multilayer structures is known to provide ballistic protection in body armor. The multi-layered bulletproof vest has been tested as a satisfactory body armor for men and women, but there are difficulties in providing comfort for women who use it, which arise from giving the body armor a special shape to fit the female body.

Wearing comfort and the effectiveness of protective clothing in preventing injury are closely related.

Depending on the level of protection and the type of fabric, from 10 to 50 layers of fabrics are used. In this way, something similar to an inflexible structure is produced, which is difficult to adapt to the clear contours of the body, namely to the area of the female bust. If the body armor does not make comfortable contact with the body of the wearer, the shock transfer becomes uneven and the body armor does not perform as it should. The areas of the body armor, which have a special shape, are largely responsible for the damage from shots at an angle of incidence equal to the angle of slip. Moreover, the female bust has a special ability to injure from a traumatic shock.

Various proposals have already been invented for a multi-layered bulletproof vest that is given a special shape to protect specific areas of the body, such as a woman's bust. But in the production of multi-layer protective clothing of a special shape, difficulties arise in that the layers of material that has resistance to puncture are flexible but relatively inelastic. This is how problems arise.

Providing the contour of the front panel of protective clothing by connecting cut strips of fabric with crossing seams and using special sewing patterns (patterns) was proposed in

US Patent 4,183,097. But, if the crossing of seams is not large enough, angled shots can pierce the vest, because increasing the size of the crossing seams creates a heavy dinner in the area where a woman needs as much flexibility as possible.

US Patent 4,578,821 proposes the insertion of a flexible multi-layer ballistic panel into the front cavity of a wearable garment. This panel is held in place by Meisgo hook-and-loop fasteners, which makes it possible to adapt to different bust sizes, but the protected area is limited and the Meisgo fastener cannot provide good ballistic protection. Thus, this system is only suitable for low levels of protection.

U.S. Patent No. 2,231,481 discloses a vest having an interior of a foamed plastic material that is shaped to conform to the bust. The formed rigid or semi-rigid shock absorbing sheet is added to the layers of plastic and as a result, a multi-layered ballistic package is obtained, the whole structure is added to the pocket. With this device, the ballistic package adapts to the shape by wrapping around a horizontal line. This can only be achieved by leaving large openings on the left and right side of the chest, so protection in these side areas will be questionable. Moreover, the vest will be relatively heavy, inflexible and uncomfortable to wear.

Another suggestion, made in US Patent 5,020,157, was to use rigid, inflexible cups made of a strong polyethylene material worn over a woman's bust and under a relatively soft body vest to protect against ballistic injury. Despite this, the shock-generating pressure is transmitted to the edges of the cups, which can cause injury. Additionally, inflexible cups can be uncomfortable to wear.

German patent UOE-A-4423194 and international publication UUO 96/01405 offer armored clothing for the body, which is given a shape by forming layers of aramid fabric in a polyvinyl chloride shell using a pressure of 400-800kPa and a temperature of 180-300"C. But aramid fibers can be stretched up to 495, this stretching can lead to failure during forming. Moreover, shaping the layers of material that stretches the fabric, which can lead to increased voids between the fibers and reduce ballistic effectiveness. Also, this forming in the polyvinyl chloride shell makes armored clothing relatively hard.

The above-described prototype proposals for special shaped multilayer protective clothing do not have a successful, manufacturable, lightweight multilayer structure that fits comfortably on the body while providing good ballistic protection and that can be produced using affordable equipment. which works at normal temperature.

The essence of the invention

The object of the present invention is to eliminate the above-mentioned problems of prototypes and to provide multi-layered protective clothing, of a special shape, which would fit the body area, of a special shape, and which would combine reliable ballistic protection and a high level of comfort.

The object of the present invention is also to provide a simple way of giving shape to such protective clothing, which does not require hot processing, which reduces the characteristics.

The objectives are achieved through the application of a new technology of bending the turns to form layers, which are given shape by more or less uniformly distributing the turns in a changing (angular displacement) sequence, as described below.

The invention provides armored clothing, namely a bulletproof vest, which is made of multiple layers of flexible, relatively inelastic, puncture-resistant material that is specially shaped to fit specific areas of the body to be protected.

The term "special shape" refers to non-planar parts that have three dimensions, such as clothing.

In accordance with the invention, the layers of material are kept in shape due to a large number of turns in the sequence of layers of material. Each fold in the layer of material typically contains an M-shaped section bent toward itself and angled to one side of the fold to provide additional thickness above and below the adjacent portion of the layer.

Also, in accordance with the invention, the grooves are angularly offset to each other, with bent M-shaped sections oriented in such a way that said added thickness is distributed essentially evenly.

The light body armor obtained in this way, of a special shape, is comfortable to wear without deterioration of ballistic protection. The absence of cutouts in the grooves means that no lines of weakness are created that could contribute to bullet penetration.

The additional thickness of the bent portions of the M-sections, which is substantially uniformly distributed around the formed areas, provides additional layers of protection over these formed portions where bullets are more likely to strike at an angle of slip and cause injury. However, the presence of good ballistic protection is not the result of the thickening of these parts, but is mainly the result of the fact that it is intended not to make weak points that could reduce the ballistic effectiveness of the main layers.

The shape obtained in this way allows for a better fit to the contours of the body and, at the same time, does not impose any limitation on the amount of protection provided by the multi-layered structure.

Due to the uniform distribution, the top-bent parts do not cause an adverse physical effect on the flexibility and comfort of the protective clothing. Moreover, the excess weight of bent parts is insignificant. The bulletproof vest thus remains light and comfortable to wear and modern to increase protection against injury.

The bent M-shaped sections of the material form folds that can all be oriented in the same direction, that is, bent to one side. However, of course, these folds are oriented in different directions. In the best implementation, a pair of layers of material had folds with the same angular arrangement, with folds oriented in opposite directions so that they did not overlap each other. The layers of material that form these pairs can be contiguous to each other, but preferably are interlayers, because this increases flexibility and comfort by avoiding the pinching of folds, which can lead to stiffness or bulging.

Corner cavities may be left between the folds where convenient, thus corner cavities may be left between several or all adjacent folds having different angles in different layers. In this way, a contribution is made to the bending capacity without reducing safety. It is important to distribute the pleats at different angles so that the excess thickness is evenly distributed, avoiding bulges or stiffness that can reduce comfort and safety.

In principle, the grooves continue mainly radially from at least one point or zone of convergence. Naturally, the bends have a zig-zag angular arrangement, one to the other around the point or convergence zone, with an angle that is equivalent to or greater than the angle of the M-sections before bending. This helps to avoid unnecessary overlapping of the edges of the folded folds.

Each layer of material normally has one fold, or in the case of women's body armor of a special shape, two folds located symmetrically to each part of the two points or areas of descent. But it is also possible for each layer of material to have more folds, for example four folds on each side and which would continue above and below two points or areas of ascent.

A primary application of the specially shaped protective clothing of the present invention is a body armor that includes at least one part that is specially shaped to fit specific parts of the body, such as the torso, neck and/or collar area, or elbow, knee or other joint area Body armor can be soft or relatively inelastic or rigid armored clothing in the form of vests or arm or leg protection and other similar clothing.

A special application is a body armor specially shaped to fit the bust of the woman who wears it, and which has two concave parts placed laterally in the middle and pushed back relative to the bust. In this embodiment, the grooves have an angular displacement around each of the laterally placed concave parts, around which said additional thickness is distributed essentially uniformly.

In this women's body armor of a special shape, two concave parts, placed laterally in the middle and pushed back relative to the bust, are usually formed by grooves around the upper, lower and outer edges of the concave parts, defining a continuously formed bust ("monochasha"), which accommodates two breast.

Alternatively, two breast cups can be provided, but this is not necessary. In this case, it is possible to provide a sufficient number of folds which are arranged in a zigzag pattern, one to the other, so that the folds cover substantially the inner circular area around each laterally placed concave portion.

The ridges of this specially shaped women's bulletproof vest extend radially from two laterally located points or ascent zones corresponding to the centers of the concave parts, above and below the two points or ascent zones, and preferably continue at an angle greater than at least 180 degrees.

Body armor according to the present invention in the form of a vest typically has a front and a back panel permanently attached to each other or forming a detachable connection that is secured by, for example, MeiIsgo fasteners, the front panel is for example shaped to fit the bust of a female wearer due to the described to the new location of the loops. The invention relates to both a one-piece vest and a front panel, which can be sold separately.

The angle of the M-shaped sections of the flexible material depends on the degree of curvature required for any specific application. For most applications, the M-sections will each form an angle of about 10 to about 40 degrees.

For women's specially shaped body armor, an angle of about 15 to 30 degrees, with a suitable 20 to 25 degrees, is desirable because it provides concave portions of a shape that is acceptable for most women's breasts.

M-shaped sections have an angle of less than 10 degrees, which is possible, for example, for different neck shapes. When small angles are used, special attention should be paid to the appropriate bending and placement of relatively narrow folds (half the angle of the U-sections) to avoid the formation of bulges.

M-shaped sections that have an angle of more than 40 degrees may, for example, be necessary for different elbow shapes.

Of course, the assembled layers of material have at least three locations of folds relative to each of the two laterally positioned concave portions. However, for some applications, two fold arrangements may be sufficient, where the pleats in different layers at each pleat are bent in opposite directions to spread the excessive thickness of the pleats as much as possible.

The arrangement of the sixth placement of the folds relative to each of the two laterally placed concave parts has proven satisfactory for women's waistcoats. The maximum number of tap placements will be determined by the intended application and industrial considerations.

The shape that will be obtained due to the special arrangement of the turns, according to this invention, can be symmetrical or asymmetrical to one or more points or areas of convergence. An asymmetric shape can be provided by an asymmetric distribution of the placement of folds, a talli can accommodate the use of M-like sections (in the same or different layers of material) with different angles, or asymmetric bending of folds.

As described in more detail below, the puncture resistant material is preferably made from polyaramid fibers and, to increase puncture resistance and reduce internal deformation, one or more layers (usually the back and/or front layer of the material) may be bonded to the polymer. It is also important for body armor to accommodate one or more front pockets to accommodate ballistic panels, or to interface with other protective layers to increase ballistic protection and/or reduce internal deformation where required. For example, rigid or a semi-rigid front layer may be acceptable.

Puncture resistant material

Various types of fibers can be used in the puncture-resistant material used in the multi-layer body armor according to the present invention, such fibers containing a polyolefin, for example, polyethylene, polyimide, polyester or polyaramid, which usually have a tear resistance of at least 900 MPa according to ATM 0O-885, which is equivalent to approximately 7 grams/day. To ensure a higher level of puncture resistance, it is desirable that the fiber breaking strength is at least 2000MPa according to ATM 0-885.

Polyaramid fibers are more desirable because they can have the required tensile strength, even exceeding the desired limit of 2000MPa, and additionally have good chemical resistance.

The fibers can be present in the material in many forms, preferably as a knitted fabric, a textile fabric, as a woven structure, a unidirectional structure or a multidirectional fabric (eg fibers crossing at an angle between 20 and 90 degrees) or a non-woven (eg felt) layer. Film-like canvases with puncture-resistant material are also possible.

On production grounds, qualities such as efficiency, fit and geometric strength (well-defined stable structure) of a textile fabric made from fibers with high tear resistance are preferred. The fabric structure may conveniently be plain fabric cut in a conventional manner from 42x42cm or 28x28cm, or 14x14cm or 6.7x6.7cm rectangles, however, other fabric structures may also suitably be used, depending on the need.

The specific gravity of these fabrics is mainly from 0.02 to 0.5 kg/m, preferably from 0.05 to 0.5 kg/m? and more preferably from 0.08 to 0.Zkg/m2 in order to obtain a balance between puncture resistance and specific gravity.

If the specific weight is lower than 0.02kg/m2, the ballistic resistance of the fabric, even made of polyaramid fibers, is generally unacceptable, while if the specific weight is greater than 0.5kg/m2, the use of a large number of layers of material becomes impractical, in due to weight restrictions.

The fibers used have an acceptable denier number (which is defined as the weight in grams of 9000 meters of thread) from 0.1 to 3500, and a suitable one from 10 to 3500, depending on the required weight/ballistic protection ratio for the fabric. 1000 to 3000 denier fiber is used for less demanding applications, while for applications requiring a high level of protection/low specific gravity, 1 to 1000 denier fiber and more specifically 50 to 1000 denier fiber is preferred .

In many cases, a denier between 1 and 3000 is fine for fibers.

The fibers can be presented in an uncoated form, or in a coated form, otherwise pre-treated (for example subjected to a pre-draw treatment or a pre-heat treatment). In the case where polyaramid fibers are used, it is generally not necessary to coat or pre-treat the fiber, thus converting it into a suitable woven or non-woven layer; however, in some cases, a coating can be applied to the fibers, for example, in order to increase their connection to the polymeric continuous medium.

To increase puncture resistance and reduce internal deformation, one or more layers of the above-described fabric, typically only the front and/or back layers, can be attached to the polymer layer or impregnated with the polymer in order to take advantage of both the qualities of fibers and polymer media.

Such a composition, known from the prior art, contains a layer composed of fibers having a tensile strength of at least 900 MPa (7 grams/denier) according to A5TM 0O-885 attached to a polymer medium having a flexural modulus of 42 to 1,000 MPa, respectively to ATM 0-790, tensile strength at least at 10 MPa in accordance with ATM 0-638 and elongation to break at least 10095 in accordance with

ABTMO-638.

In such compositions, it is desirable to use a thermoplastic polymer. Acceptable polymers include special polyethylenes, polyimide, polyester ether ketones, ionomers, modified phenol-aldehyde polymers, polyesters.

Preferably, the thermoplastic polymer is an ionomer, more preferably, the ionomer contains cations selected from the group consisting of Lithium, Sodium, and Zinc, namely from 0.1 to 390 such cations by total weight.

Alternatively, the thermoplastic polymer is a modified phenolic aldehyde polymer, namely phenolic aldehyde polyvinyl butyral.

The polymeric medium should preferably have a tensile strength of at least 20MPa and an elongation at break of at least 20095, more preferably at least 30095, both in accordance with ATM 0-638.

The flexibility of the polymer layer is an important factor, both for the resistance to penetration of the environment and the comfort of wearing a body armor that contains one or more composite sheets.

It is desirable that the flexural modulus of the polymer is in the range from 42 to 1000MPa, according to ATM 0-790, namely from 50 to 800MPa.

A flexural modulus greater than 1000MPa indicates a polymer that is too stiff to effectively resist puncture or be comfortable to wear as body armor, while a flexural modulus less than 42MPa indicates a material that is too flexible to provide any effective stiffness for composition for anti-shock needs. An additional advantage of bulletproof vests containing such a polymer is the reduction of internal deformation achieved when a bullet hits the bulletproof vest.

Another important quality of the polymer layer is its density, namely from the point of view of the low specific weight (expressed in kg/m of the composition) for the ease of wearing the body armor and for the ease of supervision and rationality of development, as well as for achieving reduced weight.

It is desirable that the density of the layer containing the polymer compound is lower than 2,500 kg/m3, and especially lower than 1,500 kg/m3; ionomer polymer layers are particularly preferred in this regard if their density is less than 1,000 kg/m3.

The polymeric continuous medium can essentially be applied as a layer that can be attached to one or both sides of the fiber-containing layer, depending on the application, and in more practical conditions, if the appropriate manufacturing method allows. In the best implementation, a fiber-containing layer is introduced into the solid polymer medium in order to fix the fibers, resulting in a very strong composition. The polymer and fiber layers can be joined in a batch or continuous process by means known in the art, such as calendering, extrusion coating, gluing, impregnation, thermal bonding, and other forms of layering with of two different materials, or even by local polymerization, thus forming a continuous polymer medium with the fiber.

The preferred method of joining the fiber/polymer layer composition is thermal bonding, such as batch molding or continuous molding, particularly by means such as a belt press or calender.

When layers of such a fiber/lolymer composition are incorporated into a specially shaped body armor according to the present invention, such sheets may be formed using folds and folds as described herein; nor does it need to apply heat during this molding process. However, it would be possible to introduce one or more composites of preformed fiber/polymer layers.

Method of production

According to another aspect of the present invention, a method of manufacturing multi-layered armored clothing having a special shape begins with providing multiple layers of flexible, relatively inelastic, puncture-resistant material to compose the armored clothing having a special shape. Each layer has fold lines defining at least one crease that accommodates the normal

M-shaped section of the material, the bends of different layers have an angular displacement relative to each other around at least one point or convergence zone.

First, the edges of the M-shaped sections are joined together to form grooves in each layer, all layers with formed grooves having essentially the same peripheral shape for assembly into body armor.

Of course, all these layers are identical in shape and size. However, it is sometimes possible to arrange layers with slight differences in shape and size, for example to accommodate gradual formation, such as gradual layer building.

Then, the multiple layers assembled to form the formed part with the grooves of the different layers having an angular offset to each other and the M-shaped sections of the material are bent in the directions necessary to distribute the thickness substantially uniformly around the formed part.

The forming operation is performed with the appropriate support. To form a vest, for example, layers can be built on the bust.

Finally, the multiple layers formed in this way are assembled to form the armored clothing.

The sequential construction of angularly displaced ('rotating') folds with bent folds in successive layers (from the Me2 layer) can be attributed to gradual contouring, as ways of contouring during successive layering up to 30, 50 or more layers.

In this way, armored clothing can be sewn by building it into an anatomically accurate shape. Each individual layer of a relatively inelastic material that has resistance to puncture can be formed by folding, connecting turns, folding folds and building successive layers.

On the one hand, there is the possibility of sewing clothes such as vests, taking individual measurements of the wearer. On the other hand, molded garments such as vests can be tailored to fit different users.

The method of folding and stapling does not require special equipment and accessories, but can be performed by existing methods of modern textile cutting equipment.

The advantage of this method of assembly is that the multi-layered form can be conveniently made using relatively thin layers of material that has resistance to puncture, by connecting a large number of layers, say 50 or more. It is well known that ballistic protection increases with the number of layers, even with a similar absolute thickness.

Preferred pairs of material layers have grooves with similar angular locations, and M-shaped parts of these layers are bent in opposite directions in such a way that they do not lie on top of each other, pairs of layers with grooves at similar angular locations are preferably arranged in alternative layers.

Thanks to this new method of building thick protective layers, the layers are increased (when overlapping where the folds are bent from above), which provides additional protection against ballistic impact, useful especially in areas of special shape where bullets or fragments hit at an angle (ie in a non-perpendicular impact).

The edges of the M-shaped sections can be stitched together to form loops, preferably using polyaramid thread. Alternatively, these edges may be attached by other means, such as polyaramid staples or rivets, or by gluing. Layers of impact-resistant material are conveniently joined by stitching.

When the layers of material are joined together, care must be taken to maintain shape and prevent air pockets from forming. The front panel of the bulletproof vest can be made by joining together two or more layers of a puncture-resistant material formed by stacking the layers with angular displacement grooves as described above.

Detailed description of drawings

Fig. 1 shows a lightweight bulletproof vest that includes a front panel 10, which is specially shaped to conform to the bust of a female wearer, and a back panel 20, each of which is made of a puncture-resistant composition, the front panel 10 has an upper chest section 14 and a lower chest section 15 formed in the middle of two concave portions which are placed laterally in the middle and are pushed back relative to the bust. Inner layers of puncture-resistant material complete the front panel 10 and are formed by a sequence of corrugations having an angular displacement, as will be described with reference to Figs. 3-15 and 17-20.

As shown in Fig. 17, the front and back panels 10, 20 of the vest are tied together, with the possibility of separation, by a series of MeIsgo fasteners, namely, MeIsgo villi fasteners 11 on the upper part of the front panel 10, which connect to MeIsgo - hook fasteners located on the shoulder straps 21, adjacent to the side panel 20, and Meisgo riie fastener 12 in the lower part of the front panel 10, connected with Meisgo fasteners hooks located on the side of the belts 22 adjacent to the lower part of the back panels 20. These side straps 22 are located on the additional crossbar 23 and, for additional security, the strap 24 is equipped with Velcro fasteners.

Layers of puncture-resistant material finishing the front panel 10 are added between the outer cover sheet and a spacer of non-puncture-resistant material. To adapt these outer sheets to the shape of the front panel 10, seams 17 are provided, extending to and above the bust level. However, it is particularly noted that, according to the invention, the inner layers of the puncture-resistant material did not have any incisions, but were composed of a series of folds having an angular displacement and having bent folds, as described below with reference to Fig. 3 -15 and 17-20.

If desired, the outer cover sheet has a crease with bent pleats similar to the inner layers made of a material that resists puncture.

Fig. 3 through 14 each show the right half of one of twelve layers 30 made of a puncture-resistant material prior to assembling the sequence of layers to form the front panel 10 of the specially shaped body armor shown in FIG. 1. The other half of each layer 30 is a mirror image with respect to line X. The lines shown in the middle of the perimeter of each layer 30 are only guidelines that serve to indicate the lines along which the bending and joining is done.

Each layer 30 has two side extensions 31 (corresponding to the parts of the front panel 10 adjacent to the waist of the wearer), a concave side 32 (corresponding to the parts of the front panel 10 adjacent to the hands of the wearer), rounded upper parts 33 (corresponding to the parts of the front panel 10 covering the upper part of the wearer's chest, i.e. where the fasteners 11 are attached), and a concave top 34 (corresponding to the part of the front panel 10 that fits and covers the wearer's neck).

Each half of the layer 30 also has an M-shaped section 35 which has a central fold line 36 around which it can be bent and joined to form a fold as shown in Fig.15. This figure shows a layer corresponding to that in Fig. 3 or Fig. 5. As shown, ply 30 is bent about a vertical fold line 38 coinciding with fold line 36, whereupon ply 30 may be joined by stitching or stapling along line 37 defining M-shaped section 35 to form a fold along the join line 37, leaving a fold 40 which accommodates the M-shaped section 35 bent around itself.

As shown for layers 30 of FIG. 17 to 20, when two folds are formed in the right and left portions of each layer 30, the outer perimeter of the layer 30 takes a shape that is substantially similar for all layers and is consistent with the shape of the perimeter of the front panel 10. However, successive layers 30 may have different sizes and shapes, as well as the functions of the building form.

By comparing Fig. 3 to 14, it can be seen that successive layers have ridges 37 angularly offset from each other around a meeting point 39, each sheet having two laterally placed meeting points 39 corresponding to the centers of the concave portions on the front panel 10, that are adapted to hold the breast. These convergence points 39 have a similar arrangement for all twelve layers 30. It is understood that the pointed ends of the protrusions 37 can be spread around the convergence zone, for example a circular zone, which is not folded as a result. Such a zone will be large enough to avoid undulations and unwanted "doubling" at the point of descent.

Pairs of alternating layers of material 30, namely those shown in Fig. 3 and 5; 4 and 6; 7 and 9; 8 and 10; 11 and 13; 12 and 14 are similar, so the ridges 37 of the layers of each pair are arranged with a similar angular arrangement. The protrusions 37 of the sequence of layers (Fig. 3, 4, 5 and so on) have an angular offset to each other. Those depicted in figures 3, 4 and figures 5, 6 are at an angle of 180 degrees to each other; those of the sequence of layers having different angles are represented in the figures with 7 to 14 lines of folds 36. As a rule, the folds 37 in the odd-numbered layers are located at the top and the folds in the even layers are located at the bottom of their layer 30, with the exception layer 30 shown in Fig. 12 where the grooves are located in the middle.

In this example provided, the M-angle between the lines 37 forming each turn is approximately 22.5 degrees, so the six side-by-side turns will extend more than 135 degrees. However, it can be seen that the full extension of the loops 37 over an angle of about 195 degrees, which starts at one end of the top from the loops 37 of Figs. 11 and 13, to the loops 37 of Figs. 4 and 6 at the other end of the lower part, causes the cavity between other grooves 37 - see Fig. 2.

As shown in fig. 17 to 20, the folds 40 associated with the folds 37 are bent in opposite directions in order to obtain the best possible distribution of their excessive thickness when the layers 30 are connected. Each pleat 40 occupies half the width of the M-shaped section and these pleats 40 are selectively bent in opposite directions.

In Fig. 17, the left fold 40 at the top of the first layer 30 is bent to the right and the right fold 40 is bent to the left.

Also, in Figure 18, the left fold 40 at the bottom of the second layer 30 is bent to the right and the right fold 40 is bent to the left.

For the respective next two layers shown in Figures 19 and 20, the bending of the respective pleats 40 is reversed, that is, for the third and fourth layers 30, the left folds 40 are bent to the left and the right folds 40 are bent to the right.

A similar pattern of reverse bending of folds 40 is followed in successive groups of paired layers 30.

The principle is that the folds 40 in the recesses 37 are located in opposite layers - similar to those on

Figures 7 and 9 and fig. from 8 to 10, for example, - will be bent in opposite directions, so that when the layers 30 are folded, these folds 40 will not overlap each other (see Fig. 2). This folding of the pleats 40 can be done when the folds 37 are formed, or when the layers 30 are folded.

Layers 30 with their folds 37 are then folded sequentially on the bust, with folds 40, of successive layers as described above. Each layer 30 is fitted on the next (or previous) layer by needle stitching. A similar process is repeated for all twelve layers 30, laying the folds 40 in selected directions on top of the layer 30, except for the last layer, in which the folds can be turned in the middle in order to obtain a smoothed outer surface.

The folded and formed layers 30 are clamped and stitched (or otherwise stapled together) around their perimeter, paying attention to holding their shape during stitching and squeezing out air to avoid air pockets. For this, it is preferable not to sew continuously around the perimeter, but to sew the peripheral sections one at a time, starting from the round upper parts 33 and ending at the lower corners. If necessary, the part corresponding to the waist can be provided with a better shape.

By means of the recesses 37, the folded layers 30 are shaped to form two laterally placed concave portions into a single cup-like configuration adapted to conform to the breast of the wearer, and the pleats 40 in the various layers 30 are oriented in directions such that the additional thickness is distributed substantially evenly around the molded parts, preventing bulges or stiffness.

Fig.2 schematically shows the angular distribution of folds 40 in a folded package. In this figure, folds 40 are identified by the numbers 111-112 of their respective layer 30 relative to FIG. from C to 14. In this example, looking clockwise, pleats 1 11-19, 1 3-11, 17-15, 112-110, 1 6-I 8 and 12-14 are placed together in pairs bent in opposite directions relative to the lines forming their folds 37. Folds I 1-1 7, 1 5-12,

10-16 and 18-12 are all spaced apart from each other by the expansion of layer 30, which is not covered by folds.

Due to the staggered arrangement of the folds 37 and the selective orientation of the folds 40, not one fold in the package overlaps another. Moreover, the folds 40 whose outer edges coincide with each other at an angle - in these examples 3 and Г9 - are separated by a part that does not have folds on at least one inner layer 30 - namely layers 1 4-I 8 - thus there is no no risk of interference between the folds 40, which may cause pinching or bulge formation.

In the final configuration, the pleats 40 are evenly distributed around the outer parts of the integral cup-like concave shape, providing two layers with a high level of protection in these sensitive areas, in the places that are covered by the pleats 40.

If it is necessary to have two zones with a high level of protection over the uncovered zones in Fig. 2, then this can be achieved by simply adding additional layers to the package, with recesses in them in the necessary additional places.

The front panel 10 in Fig.1 can be made by fitting together a selected number of packages of twelve layers 30 stacked as desired, such as two packages assembled into a 24-layer panel or three packages assembled into a 36-layer panel, and so on. It is also possible to do fragmented assembly, for example, two and a half packages assembled into a 30-layer panel.

Figure 16 shows how layers of puncture resistant material can be assembled to form the back panel 20 of Figure 1. Here, the layers 50 formed to form the back panel 20 are placed together, bent according to the back shape, then stitched or otherwise joined together. All layers 50 except the last 5th layer are stitched together around their perimeter 51 and staggered 52.

The last 5 layers 50 (which will thus be closest to the body) are sewn together only around the perimeter of 51.

The packets are then sewn together only in the top zone and in the side zones of the perimeter 51.

The front and back panels 10, 20 are then added to their respective cover layers and aligned, and the Velcro fasteners and straps are fitted.

Examples

The molded front panel of the bulletproof vest is made as described above with 30 layers of Kemiamhuge Z6Z3E fabric and stitched using 930 cm Kemiagke sewing thread. Kemiagke is a registered trademark for the goods and services of DuPont. -64-97cm (size 42). The final molded front panel was mounted in Riauzipa backing material and subjected to standard ballistics tests. Bullets were directed into the apex, side, and border of the round chest under standard conditions. All bullets were retained in the first half of the package, which indicates a good ballistic design. Moreover, the deformation of the substrate from Riavziip was satisfactory. today V m 2 / Y ( W x H x : 15-х and ЙЙ 1-- / -р-6 ----- and and
