Abstract

Protective clothing, in particular body protective clothing for female wearers, is made of a multilayer 30 of a penetration-resistant material, such as, for example, polyaramid fibers, and is specifically shaped to fit over the shape site to be protected, for example the female wearer's chest. . The shape portion of the protective garment is held in shape by a series of daart 37 in the continuous material layer 30. Each daart of the material layer typically includes a V-shaped compartment 35 whose edges 37 are joined to form the daart. The V-shaped section 35 of material is folded by itself to form a pleat 40, which is folded over one side of the daart 37 to cover or spread underneath the material 30 of the adjacent area. To form thickness. The daart 37 is angularly divided with the corrugations 40 oriented in various directions so that the added thickness is substantially evenly distributed, thereby giving a more comfortable fit avoiding bulging or stiffness.

Description

Specially Shaped Multilayer Armor

It is known to use high strength fibers, such as polyaramid fibers, as multi-layered structures to protect from projectiles with body armor. Multi-layer bullet defense vests have proved very satisfactory as body armor for men and women, but have encountered challenges in shaping armor to fit the female body to provide comfort to female wearers.

Comfort The fit and effectiveness of protective clothing to prevent injury are closely related. About 10-50 layers of fabric are used depending on the level of protection and the type of fabric. This creates a rather rigid structure and is therefore not easily applied on protruding body contours, especially on the female chest. If the protective clothing is not worn in line with the wearer's body, the shock transmission will be uneven and the body protective clothing will not perform its role properly. The shape portion of the body protective clothing is particularly susceptible to damage by bullets of an accidentally missed angle. Moreover, women's breasts are particularly vulnerable to traumatic impact.

Various proposals have already been made for specially shaped multi-layer body armor to protect the shape of the body such as women's breasts. However, the fact that the penetration-resistant material layer is flexible but relatively inelastic has made it difficult to produce unusually shaped multilayer protective garments. Thus, I ran into a problem.

It is proposed in US Pat. No. 4,183,097 to form a frontal garment panel contour by joining the cut panels of the fabric with overlapping seams using a unique stitching pattern. However, if the overlapping seams are not large enough, angle shots can penetrate the vest, while larger overlapping seams create hard edges in areas where women need more flexibility as possible. do.

U.S. Patent No. 4,578,821 proposes inserting a flexible multilayer bullet panel into the front pocket of a wear garment. These panels are held by Velcro hook-and-pile fasteners that are adjustable to the size of the chest, but the protected area is limited, and the Velcro fasteners cannot be safe from good projectile performance. As such, this system is only suitable for low protection levels.

British Patent No. 2,231,481 proposed a vest with a foamed plastic material shaped to fit the inner part to the chest. Shaped hard or semi-hard shock-absorbing sheets are added to the plastic layer, and finally a multilayer projectile (defense) pack is inserted, and the entire array is sealed in one bag. In this design, the projectile (defense) pack is shaped by folding the horizontal line almost. This can only be achieved by leaving large openings on the left and right sides of the chest, so protection of these side areas will be questionable. Moreover, the vest will be relatively heavy, hard and inconvenient to wear.

Another proposal in US Pat. No. 5,020,157 was to cover a female breast using a rigid non-flexible cup made of high strength laminated polyethylene material in a conventional soft body vest to prevent injury from projectile impact. Nevertheless, the impact-producing pressure will be delivered to the edge of the cup which may cause injury. Hard cups will also be inconvenient to wear.

It has been proposed in DE-A-4423194 and WO 96/01405 to mold body armor by molding an aramid fiber layer of a PVC shell under a pressure of 400 to 800 kPa and heating at a temperature of 180 to 300 ° C. However, aramid fibers have an elongation of 4% or less and can be damaged during molding. Moreover, the layered shape stretches the fibers to increase the spacing between the fibers and reduce the projectile defense efficiency. In addition, this molding of the PVC shell makes the protective clothing relatively rigid.

Therefore, while the conventional proposals for the above described uniquely shaped multilayer body armor can be made using useful devices operating at ambient temperatures while providing good protection against the projectile, they fit comfortably and are lightweight. Failed to produce a multilayer structure.

Summary of the Invention

It is an object of the present invention to obviate the above mentioned problems of the technology and to provide a multi-layered garment suited specifically to fit over the shape site to provide reliable protection and high fit for projectiles.

It is also an object of the present invention to provide a simple method for shaping such multilayered garments that does not require heat treatment which reduces performance.

This object is achieved by a novel-daart folding technique for producing layers shaped by daart which are somewhat uniformly distributed in rotational order (angularly offset), as described below.

The present invention provides protective clothing, in particular body protective clothing, made of multilayers of flexible, relatively inelastic, penetration-resistant materials that are specifically shaped to fit well over the shaped site to be protected.

"Specially shaped" means to go beyond the plane of a three-dimensional structure, like a garment.

According to the invention, the layer is held in shape by a number of daart in a continuous material layer. Each daart in a layer generally includes a V-shaped partition that is edged to form a daart, the V-shaped partition folded on its own and folded on one side of the daart, so that a portion of the adjacent layer is folded. Overlap or underlay to form added thickness.

In addition, according to the invention, the arts are angularly divided with the V-shaped partitions oriented such that the added thickness is distributed substantially evenly.

The resulting uniquely shaped lightweight protective clothing provides a comfortable fit without compromising the protection of the projectile. The absence of cuts in DaArt means that no weak lines are made that could allow the projectile to penetrate.

The added thickness of the folded portions of the V-shaped compartments, which are substantially evenly distributed around the shape site, provide an additional layer of protection on these shape parts which are prone to projecting at an angle at which the projectile misses. However, good protection against the projectile is not due to this thickness part, but mainly due to the fact that the design does not produce a weak part which reduces the efficiency for the projectile of the main layer.

The shape thus produced allows for better fit to body contours without limiting the protection provided by the multilayer structure. Due to their even distribution, the folds do not affect the flexibility and fit of the garment. Moreover, the additional weight of the folded part is not large. Thus, body protective clothing is lightweight, comfortable to wear and increases protection against injury.

The folded V-shaped sections of material all form wrinkles that can be oriented in the same direction, ie can be folded in the same plane. Typically, however, these corrugations are oriented in the other direction. In a preferred embodiment, the pair of material layers have daart at the same angle position. These pairs of material layers may be adjacent to each other, but advantageously these alternating layers give a more comfortable fit by avoiding overlapping wrinkles that can result in bulge or stiffness.

By placing each gap in a convenient part between the daarts, a corresponding respective gap may be placed between some or all of the adjacent pleats of the other layer. This can contribute to the flexibility of the shaped part without reducing safety. It is important to avoid bulging or stiffness that can reduce comfort and stability by angling the wrinkles in such a way that the added thickness is evenly distributed.

In principle, daart extends radially from one or more concentration points or sites. Typically, daart is staggered from one another to another in the vicinity of one focal point or area by an angle equal to or greater than the V-shaped partition before folding. This avoids unnecessary overlap of folded fold edges.

Each layer of material typically has one daart, and in the case of women's specially shaped body armor, two daarts are arranged symmetrically on each side of two concentration points or sites. However, each layer of material may have more daart, for example four daart on each side extending above and below two concentration points or areas.

The main field of application of the specially shaped protective clothing of the present invention includes one or more portions shaped to fit well over shaped portions of the body, such as torso, neck and / or collar areas, shoulder areas or elbows, knees or other joint areas. It is a body protective suit.

A particular application is body armor that is specifically shaped to fit over the breasts of a female wearer, with two side-blank internally recessed portions corresponding to the breasts. In this embodiment, the daart is folded angularly around the two concave portions of each side-blank and the added thickness around it is substantially evenly distributed.

In such women's uniquely shaped body armor, the two side-blank recessed portions corresponding to the breasts are usually continuous shaped breasts ("mono-cups") to accommodate the two breasts. Formed by daart around the top, bottom and outer edges of the recess.

Alternatively, two chest cups may be provided but this is not necessary. In this case, it is possible to provide sufficient daart staggered with each other such that the folds cover substantially the entire circle area around each side-blank recessed portion.

The daart of this female's uniquely shaped body armor is radially expanded from the two focused side-spaces or areas, corresponding to the center of the concave part, below and above the two focused points or areas, preferably The overall angle extends beyond about 180 degrees.

Body armor according to the invention in the form of a vest typically has front and rear pannels that are permanently tightly coupled or loosely filled by, for example, Velcro fasteners, and the front panel is, for example, the novel DaArt arrangement described. It is shaped to fit the breast of the female wearer. The present invention relates to both the entire vest and the front panel which can be sold separately.

The angle of the V-shaped section of the flexible material depends on the degree of bending required for any particular application. In most applications the V-shaped compartments can be at an angle of about 10 to 40 degrees each.

In women's uniquely shaped body armor, an angle of about 15 to 30 degrees, preferably about 20 to 25 degrees, is desirable to provide a concave portion of a shape suitable for most female breasts.

V-shaped compartments with an angle of less than 10 degrees are possible for example for neck shape. If small angles are used, special care will be needed to fold properly and to place relatively narrow creases to avoid bulging.

V-shaped compartments with angles greater than 40 degrees would be needed, for example, in the elbow shape.

Typically, the assembly of the material layer has three or more daart positions around the two respective side-blank recesses. However, in some applications only two daart positions may be sufficient, where at each daart position the pleats of the other layer fold in opposite directions to unfold the added thickness of the possible pleats.

An arrangement with six daart positions around two concave portions of each side-blank has proved very satisfactory for women's vests. The maximum number of daart positions is determined by the listed uses and manufacturing considerations.

The shapes produced by the specific arrangement of daart according to the invention may be symmetrical or asymmetrical with respect to one or more concentration points or sites. Asymmetrical forms may include using asymmetric distributions of daart positions, and / or using V-shaped partitions (in the same or different layers) with different angles, and may be provided by asymmetrical folding of the folds. .

As discussed in detail below, the penetration-resistant material is advantageously made of polyamide fibers, improves penetration resistance, reduces backface deformation, and has one or more layers (typically only the backside and / or ) Front layer) can be bonded to the polymer. In addition, body armor may include one or more front pockets for receiving projectile (defense) panels, or may be associated with other protective layers, to enhance projectile (defense) performance and / or reduce backside deformation as needed. Can be. For example, the hard or semi-hard front layer can be fitted.

Penetration-Resistant Materials

Penetration-resistant materials used in multi-layer body armor according to the present invention have several types of fibers, such as polyethylene, poly, having a strength of at least 900 MPa in accordance with ASTM D-885, which is equivalent to about 7 g / denier. Fibers comprising polyolefins such as mids, polyesters or polyaramids can be applied. In order to provide good penetration-resistance, the strength of the fibers is preferably at least 2000 MPa according to ASTM D-885.

Polyaramid fibers exceed the preferred 2000 MPa limit, but are preferred because they can have the required strength and also have good chemical resistance.

The fibers are many types of materials, preferably knitted fabrics, woven fabrics, uniweave structures, unidirectional structures or multidirectional sheets (eg having fibers that cross at an angle of 20 to 90 degrees), or It may be present as a nonwoven (eg felt) layer. Film like sheets of penetration-resistant materials are also possible.

High strength fabrics are preferred to give efficiency, usability and geometric strength (well defined stable structures). Fabric configurations may also be used with different fabric configurations depending on the requirements of the application, but suitably typically 42 x 42 or 28 x 28 end / cm, or 14 x 14 or 6.7 x 6.7 end / cm It may be a plain weave consisting of.

The specific gravity of such fabrics is usually from 0.02 to 0.5 kg / m ² , preferably from 0.05 to 0.5 kg / m ² , more preferably from 0.08 to 0.3 kg / m ² for the balance between penetration-resistance and specific gravity.

Proportion of resistance to the fabric projectile is less than 0.2 kg / m ² can not be normally acceptable, even when made from polyaramid fibers, the specific gravity is due to the multiple layers of fabric using the constraints of a weight exceeding 0.5 kg / m ² It becomes impractical.

The fabric used has a suitable denier (defined as g weight of 9000 meter yarn) of 0.1 to 3500, suitably 10 to 3500, depending on the desired fabric weight / projectile defense performance. Fibers having deniers of 1000 to 3000 are used for less applications, and fibers having deniers of 1 to 1000, more particularly 50 to 1000, are preferred for high performance / low specific gravity applications.

In many cases, fibers having a denier in the range of 10 to 3000 are excellent.

The fibers may be present in uncoated or coated form, or otherwise in a pretreated form (eg, pre-stretched or heat treated). When polyaramid fibers are used, there is usually no need to coat or otherwise pretreat the fibers other than arranging the fibers in a suitable woven or nonwoven layer; However, in some cases, coatings may be applied to the fibers, for example, to increase their binding to the polymerizable continuum.

In order to improve penetration-resistance and to reduce backside deformation, one or more layers of the above-described fabric, typically only the backing layer and / or the frontal layer, are bonded to the polymer layer or utilizing both the properties of the fiber and the polymerizable continuum. It may also be impregnated with a polymer in order to do so.

The composites described in EP-A- (KB-4060) have a softening factor of 42 to 1,000 MPa in accordance with ASTM D-790, a tensile strength of at least 10 MPa at burst according to ASTM D-638, and an elongation at break of 100% according to ASTM D-638. A layer comprising a fiber comprising, in accordance with ASTM D-885, having a strength of at least 900 MPa (which is equivalent to about 7 g / denier) bonded to a polymeric continuum having

In such composites preferably thermoplastic polymers are used. Suitable polymers include certain polyethylenes, polyimides, polyester etherketones, ionic resins, phenolic-modified resins, polyesters.

Preferably, the thermoplastic polymer is an ionic resin, more preferably an ionic resin comprising from 0.1 to 3% by weight of a cation selected from lithium, sodium and zinc. to be.

Alternatively, the thermoplastic polymer is a phenolic modified resin, in particular phenolic-polyvinylbutyral resin.

The polymerizable continuum should preferably all have a tensile strength of at least 20 MPa and at least 200% elongation at break, more preferably at least 300%, according to ASTM D-638.

The flexibility of the polymer layer is an important factor in the penetration-resistance of the composite and the comfortable fit of body armor to insert one or more composite sheets.

The softening coefficient of the polymer is preferably 42 to 1000 MPa, in particular 50 to 800 MPa according to ASTM D-790.

Softness modulus of polymers higher than 1000 MPa indicates that the polymer is too hard to withstand piercing or wear comfortably as body protective clothing, whereas softness modulus of polymers less than 42 MPa is used in compositions for anti-stab purposes. It is indicated that the polymer is too flexible to provide any effective rigidity. An additional advantage of body armor comprising such polymers is that there is less back deformation that occurs when a bullet hits body armor.

A significant property of another polymer layer is its density in terms of low specific gravity, which is particularly desirable for ease of treatment and efficient manipulation for the purpose of ease of wear and weight reduction of body armor.

Preferably, the density of the layer comprising the polymer compound is 2.500 kg / m ³ and in particular 1,500 kg / m ³ and it is particularly preferred if the ionic polymer layers have a density of less than 1,000 kg / m ³ .

The polymerizable continuum may suitably be applied as a layer that can be bonded to the fiber-containing layer on one or both sides, depending on the application in a suitable manufacturing process. In a preferred embodiment, the fiber containing layer is sealed in the polymerizable continuum to fix the fibers, resulting in a very strong composition. The polymer and fibrous layers may be batchwise or by any means known in the art, such as, for example, calendering, extrusion coating, adhesion, impregnation, thermal bonding, other forms of laminating two different material layers or in-situ polymerization. It can be combined in a continuous process to produce a polymerizable continuum with the fibers.

Preferred methods of joining the fiber / polymer composite layer are thermal bonding, such as molding in batch process form or continuous process form by belt press or calendar.

When a layer of such composite fibers / polymers is included in a shaped body garment in accordance with the present invention, such sheets may be shaped using daart and folded folds as described herein; It is not necessary to apply heat during this shaping process. However, it may contain layers of one or more fiber / polymeric composites that have been pre-shaped by molding.

<Manufacturing method>

According to another aspect of the present invention, a method of making a uniquely shaped protective garment is disclosed by providing a multilayer of flexible and relatively inelastic penetration-resistant material to be assembled into a shaped protective garment. Each layer generally has a tangent that defines one or more daarts comprising a V-shaped section of material, and the daats of different layers fold angularly to each other around one or more concentration points or sites.

First, the edges of the V-shaped compartments are joined to form a daart on each layer, and with all the daart formed, the layers have substantially the same periphery for assembly into shape protective clothing.

Typically, all these layers are the same in shape and size. However, it may sometimes be convenient to arrange the layers in slightly different shapes or sizes, for example, in order to control the shape that progresses as the layers are shaped.

The multi-layers are then assembled to form a shape portion, the other layers of daart are folded back to each other, and the V-shaped sections of material are folded in several directions to distribute the added thickness substantially evenly around the shape site.

This production process is carried out on a suitable support. For example, a layer can be made on the chest to make a vest.

Finally, the shaped multilayers are assembled to form protective clothing.

A stepwise preparation of angularly overlapped (“rotated”) daart with folds folded in a progressive layer (from layer number 2) can be thought of as a progressive contouring of less than 30, 50 or more layers that continue during the contouring process. .

In this way, the garment can be tailored to the correct form without cutting. Each single layer of relatively inelastic, penetration-resistant material can be shaped by folding or bonding daart, folding wrinkles and increasing continuous layers.

On the other hand, these vests can be tailored according to the measurements of the individual wearers. On the other hand, shaped garments, such as vests, can be made to suit other wearers.

Folding and tightening techniques do not require special equipment and tools but can be handled by current techniques of modern fabric cutting techniques.

The advantage of this assembly technique is that the multilayered form can be made simply using a relatively large layer of penetration-resistant material, in which a very large number of layers, ie 50 or more layers, have been accumulated. It is known that the number of layers at the same overall thickness further improves the projectile defense performance.

Preferably, the pair of material layers has daart at the same angle position, and the V-shaped portions of such layer are folded in opposite directions so as not to overlap each other, and the pair of layers having daart at the same angle position are preferred. Preferably assembled into alternating layers.

By this new technique of making thick protective layers, the layers are obtained, in particular, for bulleted or debris-shaped areas where they are hit at any angle (deviated collision) and provide additional protection against projectile impact.

The edges of the V-shaped compartments can preferably be stitched together using polyaramid yarns to form daart. Alternatively, these edges may be joined by other means, for example by other means, such as staples or rivets of polyaramid, or by adhesion. The layer of impact-resistant material is simply joined by sewing.

When the layers of material are bonded to each other, care must be taken to maintain shape and avoid the formation of air pockets. The front panel of the body armor can be made by joining together a pack of two or more layers of penetration-resistant material, shaped by assembling a layer with angularly cracked daart as described.

<Detailed Description of Drawings>

1 includes a front panel 10 and a back panel 20 specifically shaped to fit over a breast of a female wearer, each of which represents a lightweight bullet-resistant vest made by assembling a layer of penetration-resistant material. . The front panel 10 has an upper chest compartment 14 and a lower chest compartment 15 and forms two inwardly hollow recesses inwardly corresponding to the chest. The inner layer of penetration-resistant material from which the front panel 10 is made is shaped by a series of angularly offset daart as described with reference to FIGS.

As shown in FIG. 1, the front and rear panels 10 and 20 of the vest cooperate with the Velcro hook fasteners attached to the shoulder leash 21 mounted on the rear panel 20. ) Are loosely filled together by a series of velcro fasteners, ie velcro pile fasteners 11 at the top surface. This side leash 22 carries an additional velcro cross-piece 23 and is provided with a belt 24 and velcro fasteners for added protection.

A layer of penetration-resistant material for making the front panel 10 is embedded between the exterior sheet and the lining of the non-penetration-resistant material. In order to conform this outer sheet to the shape of the front panel 10, a seam 17 is provided that extends to and above the chest level. However, it is important according to the invention that the inner layer of the penetration-resistant material is free of cutouts, and only by a series of angularly-divided daart with folded folds, as described below with reference to FIGS. Are assembled.

If desired, the exterior sheet may have daart with folded folds, such as that of the inner layer of penetration-resistant material.

2A-2M respectively show the right half of one of the twelve penetration-resistant material layers 30 prior to the assembly of successive layers to form the shaped front panel 10 of the bullet-resistant vest of FIG. 1, respectively. . The other half of each layer 30 is a mirror image with respect to X-rays. The lines appearing inside the boundaries of each layer 10 merely indicate the location of the fold and bond lines.

Each layer 30 has two side extensions 31 (corresponding to a portion of the front panel 10 that fits around the waist of the wearer), and side recesses 32 (front facing under the wearer's arm). Corresponding to the part of the panel 10), circular top 33 (corresponding to the part of the front panel 10 that covers the wearer's upper shoulder, ie the part to which the fastener 11 is attached) and the concave top ( 34) (corresponding to a portion of the front panel 10 that fits around the wearer's neck).

Each half of layer 30 also has a V-shaped partition 35 having a central tangent 36 that can be folded or joined peripherally in FIG. 3 to form a daart. This figure shows a layer corresponding to the layer of FIG. 2A or 2C. As shown, the layer 30 is folded along a vertical tangent 38 that coincides with the tangent 36, and the layer 30 is along a tangent 37 defining a V-shaped compartment by stitching or stapling. Combined, it is possible to create daart along the combined line 37, leaving a pleat 40 consisting of the folded V-shaped compartment 35 itself.

As can be seen in layers 30 of FIGS. 4A-4D, when two daart 37 are formed on the right and left sides of each layer 30, the outer boundary of layer 30 is for all layers. It adopts the same shape and coincides with the peripheral shape of the front panel 10. However, the continuous layer 30 may have other sizes and shapes depending on the function of the form to be produced.

Comparing FIGS. 2A-2M, the continuous layer has daart 37 that is angularly divided around the focusing point 39, with each sheet 30 adapted to accommodate the wearer's chest. It has two side-blank concentration points 39 coincident with the center of the recess. These concentration points 39 are almost all in the same position for all twelve layers 30. This means that the pointed ends of the daart 37 may be distributed around the concentration site, ie around the circular site, and consequently do not fold. This area will be large enough to avoid twisting at the point of focus and unnecessarily "overlapping".

Alternate pairs of layers 30, i.e., FIGS. 2A and 2C; FIGS. 2B and 2D; FIGS. 2C and 2E; FIGS. 2D and 2F; FIGS. 2E and 2G; FIGS. 2F and 2H; FIGS. 2G and 2i; FIGS. 2H and 2K; Figures 2I and 2L; Figures 2K and 2M are the same because the daart 37 in each pair of layers lies at the same angle position. Consecutive layers of the art 37 (FIGS. 2A, 2B, 2C, etc.) diverge from each other. The arts of FIGS. 2A, 2B and 2C and 2D are 180 degrees with respect to each other, and the art of the remaining continuous layer is the different angle shown in FIGS. 2E-2M by tangent 36. In general, even-numbered daart 37 is positioned on top, except for layer 30 of FIG. 2K where daart is centered in the middle, even-numbered daart 37 of the layer 30 Is located at the bottom.

In these examples, the V angle between the lines 37 forming each daart is about 22.5 degrees, so that the six daarts placed side by side widen to 135 degrees. However, the entire daart 37 starts at one upper end of the daart 37 of FIGS. 2i and 2l and extends about 195 degrees up to the lower one end of the daart 37 of FIGS. 2b and 2d. As can be seen, there is a space between the rest of the daart 37 (see FIG. 5).

As shown in FIGS. 4A-4D, the corrugations 40 associated with the daart 37 are folded in alternating directions with respect to each other so that the added thickness of the layers 30 are possible during assembly. Each pleat 40 occupies one-half the width of the V-shaped compartment, and these pleats 40 are selected and folded in an alternating direction.

In FIG. 4A, the left pleat 40 above the first layer 30 folds to the right, the right pleat 40 folds to the left, and in FIG. 4B the left pleat 40 below the second layer 30. ) Is folded to the right and the right pleat 40 is folded to the left.

In the next two corresponding layers of FIGS. 4C and 4D, the folding of the corresponding corrugation 40 is inverted, ie the left corrugation 40 is to the left in the third and fourth layers 30, Right pleat 40 is folded to the right.

The same pattern continues with the pairs of layers 30 followed by the folding of the pleats 40 in the opposite direction. The principle is that, for example, as in FIGS. 2E and 2G and FIGS. 2F and 2H, the corrugations 40 of the daart 37 lying in the same position in the alternating layers are those corrugations 40 upon assembly of the layer 30. ) Are folded in half direction so as not to overlap each other (see FIG. 5).

Then, together with these daart 37, the layer 30 is continuously assembled on the chest while the corrugation 40 of the continuous layer is folded as described above. Each layer 30 is fitted on the next (or previous) layer by the yarn. Except for the last layer where the pleats are directed inwards to make the outer surface smooth, the same process is performed for all twelve layers 30 while the pleats 40 are placed in the selected direction above the layer 30. Is repeated.

The assembled and formed layers 30 remain clamped and are sewn (or fixed to each other) around them while processing to maintain shape during sewing and air compression to avoid the creation of air pockets. For this purpose, it is preferable to sew the peripheral section once at a certain interval starting from the circular top 33 and finishing at the lower corner rather than stitching the periphery continuously.

Due to the daart 37, the assembled layer 30 is shaped to form two side-blank recessed portions in the form of a mono-cup that fits well over the wearer's chest, and the pleats 40 in the various layers 30. ) Are oriented in several directions so that the added thickness is substantially evenly distributed around the shaped portion to avoid bulging or stiffness.

5 schematically illustrates the distribution of the angle of the pleats 40 in the assembled pack. Corrugations 40 in this figure are identified by the numbers L1 to L12 of their respective layers 30 corresponding to FIGS. 2A-2M. In these examples the corrugations L11-L9, L3-L1, L7-L5 L12-L10, L6-L8 and L2-L4 in the clockwise direction are arranged together in pairs folded in opposite directions with respect to the lines forming their daart 37 do. The pleats L1-L7, L5-L12, L10-L6 and L8-L2 are all angularly spaced apart from each other by the large space of the layer 30 which is not occupied by the pleats.

Due to each staggering of the daart 37 and the optional orientation of the pleats 40, the pleats in the pack do not overlap each other. Furthermore, the corrugations 40-for example L3 and L9-whose outer edges of the corrugations are angularly matched with each other are separated by at least one unpleasant portion of the intermediate layer 30-ie layers L4-L8-. There is no fear of overlapping or bulging due to interference between the pleats 40.

In the final assembly, the pleats 40 are evenly distributed around the outer periphery of the mono-cup recess, providing two additional layers of protection in this sensitive area at the location covered by the pleats 40.

The front panel 10 of FIG. 1 fits a selected number of packs of twelve layers 30 assembled together, as described, for example, two packs comprise 24-layer panels, or 2 Packs can be made, including 36-layer panels, and the like. It is also possible to assemble a two and a half pack comprising, for example, a 30-layer panel.

FIG. 6 illustrates a method by which the layer of penetration-resistant material can be assembled to produce the back panel 20 of FIG. 1. Here, the layers 50 shaped together to form the back panel 20 are put together, bent in the form of the back, and then sewn or otherwise attached to each other. Except for the last five, all of the layers 50 have their periphery 51 and the intersection 52 stitched. The last five layers 50, which are the closest to the body, are sewn only around 51. Thereafter, the pack is sewn together with only the upper and side portions of the periphery 51.

The front and rear panels 10 and 20 are then embedded in their respective cover layers and linings and run with Velcro fasteners and thongs.

FIELD OF THE INVENTION The present invention relates to protective garments made of multiple layers of penetration-resistant materials, and more particularly, to protective body garments comprising specificly shaped portions to fit well into the curves of the body, such as female breasts, and methods of making the same.

As described above, a shaped front panel of bullet-resistant vest was made of 30 layers of Kevlar® style 363F fabric sewn using a 930 dtex Kevlar® sewing thread. . Kevlar® is a registered trademark of DuPont. This layer was assembled on a chest measuring 94-64-97 cm (size 42). The finished shape front panel was loaded on a Plastilina support material and standard tests on the projectiles were performed. The bullet was aimed at the lateral edge of the end of the curved chest under standard conditions. All bullets were stopped within half of the pack, indicating a good projectile (defense) design. Moreover, the back strain on the plastilina was satisfactory.
