Description

Load-distributed ballistic plate of bulletproof plate and multipurpose protective clothing including the same

The present invention relates to a ballistic plate and a body armor including the same, and more specifically, the ballistic plate is supported by the ballistic plate while being accommodated in the body armor (bulletproof vest) to relieve the load and completely block moisture penetration through a barless material. It relates to a load-distributing ballistic plate of increasing bulletproof plate and a multi-purpose fusion protective suit including the same.

This part provides background information related to the content of the present application, and is not necessarily prior art.

As the industry develops, the performance of weapons for killing lives [firearms, mines and explosives, swords (blades/awls)] also improves every year (the speed of bullets and debris that are launchers is increasing and the mass is increasing). In order to secure the safety of people, the development of protective equipment suitable for the times (defense the performance of weapons for killing humans) is required (such as body armor, protective clothing, shields, helmets, explosion-proof bags, etc.). Therefore, the NIJ bullet defense standards (NIJ-0101.06) and swords defense standards (NIJ-0115.00), which are the testing standards for police body armor of the U.S. Department of Justice Institute of Justice (NIJ), are prescribed and the debris defense test method is established.

Hereinafter, protective equipment for each type of killing weapon will be classified and described.

Weapons for killing lives are largely divided into firearms (referring to firing a projectile of bullets), explosive logistics (referring to scattering (flying) fragments), and swords (referring to having sharp parts).

1. Firearms.

In general, the body armor that protects the human body from firearms is composed of a combination of a garment, a ballistic plate, and a bulletproof plate.

The ballistic plate, which is a key component of the body armor, is aimed at minimizing trauma by reducing the speed of the projectile, which is a warhead of firearms, to a stop state (speed "0").

The ballistic plate that protects the wearer from bullets must meet the NIJ THREAT LEVEL (rear defense performance within 44mm), which is the most widely recognized internationally recognized police body armor test standard of the National Institute of Justice (NIJ).

In addition, in the manufacture of ballistic plates, the following conditions must be satisfied.

First, the bullet must have good defense and meet the standard.

Second, it is necessary to consider the deformation of the ballistic plate. That is, even if the bullet does not penetrate, it is recognized as a ballistic plate with excellent performance when there is little deformation to the rear so as not to damage the body by minimizing the impact.

LEVELIIIA armor of NIJ-STANDARD-0101.06 is under 44 mm without penetration by a projectile such as a .44 magnum projectile at a speed (Vo) specified as "436 m/s +/- 9 m/s (1430 ft/s). It must have a back deformation."

Third, it should be lighter and thinner in consideration of weight and thickness, so that it has good activity.

Fourth, the fit should be good.

Fifth, the manufacturing cost should be low.

Various ballistic plates have been developed to meet these regulations, and materials for ballistic plates known to date include aromatic polyamide (PARA-ARAMID), high density polyethylene (HIGH DENSITY POLYETHYLENE), and polybenzoxazole (PBO). There is this.

As the aromatic polyamide system, there is a high elastic fiber Kevlar (KEVLAR: DuPont's trademark) fabric or Twaron (TWARON: TWARON DEIJIN's trademark) fabric, and high-density polyethylene as a film made of a polymer compound. (DYNEEMA: DSM's brand name) or Spectra (SPECTRA: HONEYWELL's brand name), and polybenzoxazole (PBO) is Zylon (trade name). In addition, a ballistic plate using ceramic (the product was developed under the name of "Dragon Skin", which did not meet NIJ standards during commercialization, and was discontinued due to heavy weight), liquid ballistic plate (known to have potential, but is generally used. Commercial development has not been possible) and others are being developed.

Such an aromatic polyamide-based high-elastic fiber fabric or a film made of a high-density polyethylene polymer compound, when the body armor is NIJ ⅢA, is each independently stacked in multiple sheets (35 to 36 sheets) and wrapped with an outer shell, or these fiber fabrics and films Are laminated in an appropriate ratio to form a ballistic plate.

Explaining the process of stopping by absorbing the impact of the bullet by the ballistic plate, the bullet starting from the muzzle is in a high temperature state due to friction with the air after firing.

When such a high-temperature bullet hits the ballistic plate, the generated impact energy is diffused in all directions as shown. After that, the progress of the bullet is suppressed by the ballistic plate, and the bullet 1 is gradually squeezed and the progress is stopped on the ballistic plate.

Accordingly, the ballistic plate must have the characteristics of absorbing impact energy well and withstanding high temperatures.

If a bullet is fired on the ballistic plate while the ballistic plate is attached to the mud plate, it can be seen that the ballistic plate is deformed by applying impact energy to the mud plate by the propulsion force of the bullet when capturing the bullet and then returns to the initial state.

Therefore, even if the ballistic plate does not penetrate by minimizing the deformation of the ballistic plate due to impact energy, the tensile strength must be sufficiently considered so that the deformation of the ballistic plate does not adversely affect the human body.

The process in which the fired bullet is captured by the ballistic plate will be described in more detail as follows.

When the kinetic energy of the bullet fired from the gun reaches the ballistic plate, the impact energy is applied to the ballistic plate, and the applied impact energy diffuses into a wave shape and is converted into heat energy, thereby generating heat.

At this time, the temperature of the bullet is gradually stopped while exceeding 150 ℃.

In this way, the bullet is stopped by the ballistic plate by the following mechanism. That is, while applying a predetermined deformation to the ballistic plate, the impact energy is diffused, the speed of the bullet is gradually slowed down, and thus the progress of the bullet is stopped.

When the yarnols of the ballistic plates stacked in several layers are deformed, the energy of impact is reduced as the impact energy is dispersed in all directions along each yarnol.

This impact energy is distributed in all directions along the yarn. When the ballistic plate is composed of several layers, the above-described operation is performed identically on the surface of the plurality of layers.

Aromatic polyamide (PARA-ARAMID), which is the material of the ballistic plate, has a higher heat resistance than high density polyethylene, while it is heavier, and high density polyethylene has a higher tensile strength than aromatic polyamide, but has a lower heat resistance. There are characteristics.

Since the conventional high-density polyethylene film is a unidirectional shield, the energy dispersing efficiency is much higher than that of the aromatic polyamide system because there is no cross-over fiber strand when a bullet touches the ballistic plate. In other words, the high-density polyethylene film has no energy dispersing and repulsive force generated by the cross-over fiber strands, so that energy is dissipated in only one direction, so the shock absorbing power is much higher than that of the aromatic polyamide system.

However, while a plurality of aromatic polyamide-based woven fabrics are used to be sewn crosswise in a state of overlapping, high-density polyethylene films are prohibited from sewing when producing ballistic plates.

This is a fatal problem that the ballistic plate penetrates because the ballistic plate is impacted and the impact energy is dispersed along the yarn, and when the high-density polyethylene film is sewn, the dispersion efficiency at the sewing point decreases rapidly, and the impact of the bullet cannot be dispersed. Because I bet.

Therefore, in recent years, HYBRIDS (a product obtained by mixing aromatic polyamide and high-density polyethylene) has been commercialized in consideration of only the merits of each material.

In other words, on the front side of the ballistic plate, a plurality of aromatic polyamide-based woven fabrics that withstand impact heat are stacked, and a plurality of high-density polyethylene films having high tensile strength and good impact absorption are stacked on the rear side to form a ballistic plate. .

However, such a conventional ballistic plate has a high heat energy of about 150°C or more of a fired bullet, and the impact heat of the front of the ballistic plate and frictional heat on the rear of the ballistic plate generated by rotation decreases the defense power of the ballistic plate, causing multiple layers of the ballistic plate. Since it had to be composed of (34~36 layers), the weight was heavy and the fit was degraded, and there was a problem in that it was not possible to supply body armor at a low price due to the composition of expensive fabrics such as high-density polyethylene in several layers.

2. Debris and explosive logistics

V50 is defined as the speed at which the penetration probability of selected fragments is exactly 50%, and ballistic plates for fragments or explosives are internationally recognized as the most widely recognized MIL-STD-662F and STANAG 2920 standards (calculated value of V50 for continued protection). It is manufactured to be satisfied.

Fragments or explosives have lower impact energy and heat than bullets, but fragments or explosives defense ballistic plates have a similar action to bullet defense ballistics as described above, and protect the wearer from fragments or explosives without being pierced by fragments or explosives.

The ballistic plate for debris or explosives is intended to protect the wearer from the debris or explosives of the surrounding structures or bombs.The debris or explosives have lower impact energy and heat than bullets, but the ballistic plate for debris or explosives is as described above. It protects the wearer from debris or explosives without being pierced by debris or explosives with a similar action to bullet defense ballistic plates.

In the conventional ballistic plate for debris or explosives defense, the ballistic plate for bullet defense is used as it is, and thus, it is very inconvenient to fit due to heavy weight, and the debris or explosives defense performance is weak in terms of defensive performance.

3. Swords (blades/awls).

In order to protect the human body when attacked by weapons with sharp ends such as knives, awls, and bamboo spears, a swordsman uniform is used.

The conventional swordsman uniform uses a swordsman board as a core part.

As with the ballistic plate (both body armor), it is manufactured in accordance with the NIJ's National Police Department of Justice Test Standard (NIJ-STD-0115.00), which is the most widely recognized internationally. It should be used as a criterion for judging whether or not it is appropriate.

For reference, when explaining the standard contents of NIJ-STD-0115.00 for the bulletin board, common threats are various swords, their sharpness, pointedness, style, handle and blade design. (handle and blade design), attacking angle (attacking angle), the physical condition of the attacker (the physical condition of the attacker) and the attacker's skill of the attacker is differently taken. Depending on the type of threat environment, it is about a machined edge or blade of good quality, which is generally regarded as an'Edged Blade' class, and a weapon such as a dull or spike of low quality. 'It is classified into two different protection classes, which are considered to be classes, and within each of the classes, the armor suit is divided into three protection levels as follows.

Level 1 swordsman uniform: A low-level swordsman suit suitable for wear.

Level 2 Swordsman's Clothing: A garment for a regular work piece suitable for wearing.

Level 3 Anti-Sword Suit: A high-level anti-sword suit worn under high risk situations.

It is of course necessary to protect the wearer from penetration from a knife, a weapon having a sharp blade, or a weapon with a pointed tip without being restricted by the movement of the wearer.

On the other hand, the ballistic plate is divided into a flexible soft armor (soft armor) and a non-flexible hard armor (HARD ARMOR) according to the shape. ARMOR is a material (fabric, etc.) that protects the projectile of bullets or fragments.

Soft protective equipment is mainly applied to clothing such as protective clothing because of its characteristics, as it is more active than hard protective equipment, and it cannot prevent moisture penetration and is weak against heat. As a result, it has a disadvantage that the protective performance is poor and the lifespan is very short compared to hard protective equipment, and hard protective equipment is hard. Due to its characteristics, it is mainly applied to small items such as shields, helmets, and bags, rather than clothing, and has the advantage of having a longer lifespan than soft protective equipment, but has low activity and heavy disadvantages compared to soft protective equipment.

As described above, the body armor is composed of a combination of a ballistic plate and a bulletproof plate having defensive performance, for example, the ballistic plate is for bullet defense, the ballistic plate is for rifle bullet defense, and the ballistic plate and the bulletproof plate have different defense performances, thus, The ballistic plate is applied to the body armor by default, and the ballistic plate is selectively applied as needed.

The ballistic plate and the bulletproof plate are inserted into the pockets of each body armor, the ballistic plate is accommodated on the wearer's body, and the bulletproof plate is inserted in front of the ballistic plate.

In this case, compared to the ballistic plate inserted into the wearer's body, the bulletproof plate farther away from the body is drooped downward by the load, and thus the upper body of the wearer is leaned forward, so there is a problem that the activity is deteriorated.

In addition, the bulletproof plate pocket is inevitably made of a size larger than the size of the bulletproof plate for storage and replacement of the bulletproof plate, and thus, there is a problem in that the bulletproof plate is shaken from side to side in the bulletproof plate pocket, thereby reducing activity.

In addition, when the outer shell of the ballistic plate is sealed with a bar material, it is difficult to completely waterproof between the two outer shells, and moisture may penetrate through the hole through which the thread passes, so that moisture penetrates the ballistic plate fabric inside the outer shell. It is known that the defense performance drops by about 20% when infiltrating.

Registered Patent No. 10-1713647

The present invention is to solve the above-described problems, by distributing the load of the bulletproof plate applied to the front of the ballistic plate to prevent the wearer's upper body from being pulled due to the load of the bulletproof plate. It is an object to provide a load-distributing ballistic plate and a multipurpose fusion protective clothing including the same.

Further, another object of the present invention is to distribute the load of the bulletproof plate and to prevent the left and right shaking of the bulletproof plate.

The load-distributing ballistic plate of the bulletproof plate according to the present invention comprises: a ballistic plate main body for surrounding and protecting a body part of a wearer; It is formed on a front surface of the ballistic plate body and comprises a bulletproof plate load distribution unit for accommodating the bulletproof plate accommodated therein to distribute the load of the ballistic plate to the ballistic plate body.

Preferably, the bulletproof plate load distribution part is formed in the shape of a groove in the front surface of the ballistic plate body to insert the bulletproof plate.

The ballistic plate body includes a plurality of ballistic plate fabrics, and includes a hard armor portion that is hardly molded by heat pressure.

According to the load-distributing ballistic plate of the bulletproof plate according to the present invention and the multi-purpose fusion protective suit including the ballistic plate, the speed of the warhead of firearms, the debris of landmines and explosives is reduced and ultimately the speed is increased by using the ballistic plate and the bulletproof plate together. Set to "0", that is, to stop the warhead of the projectile and fragments of the flying (flying) chain to prevent trauma to the wearer from the warhead and fragments, and to significantly reduce the weight felt by the wearer by distributing the load of the bulletproof plate through the ballistic plate. Therefore, there is an effect of improving the fit and effective protection of the wearer by enabling a quick and safe response to the threat of the other party. In particular, the bulletproof plate is accommodated in the outermost (front, rear) of the bulletproof suit to prevent large sagging caused by the load of the bulletproof plate, thereby maximizing the fit, activity, and stability.

In addition, by completely blocking the penetration of moisture with a seamless seal that fuses (high frequency) the edges of the outer skins, there is an effect of preventing deterioration of ballistic performance due to moisture penetration and consequently improving the ballistic performance by about 20%.

In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted. In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary depending on the intention or custom of users or operators. Therefore, the definition should be made based on the contents throughout this specification.

As shown in Figs. 1 to 4, the load-distributing ballistic plate 10 (hereinafter abbreviated as "ballistic plate") of the bulletproof plate according to the present invention includes a ballistic plate body 11 and a ballistic plate body protecting a wearer. It is formed on (11) and is composed of a bulletproof plate load distribution unit 12 that distributes the load of the bulletproof plate 20 by supporting the bulletproof plate 20.

The bulletproof plate load distribution unit 12 may be of various forms for distributing the load of the bulletproof plate 20, and is preferably in the form of a groove (or jaw) supporting the bottom of the bulletproof plate 20. The groove-shaped bulletproof plate load distribution unit 12 is formed in the ballistic plate body 11 to insert the bulletproof plate 20, and the jaw-shaped bulletproof plate load distribution unit 12 is forward from the ballistic plate main body 11 It is formed to protrude toward to support the bulletproof plate (20).

Compared with the conventional ballistic plate, the conventional ballistic plate has a flat structure on a surface opposite to the ballistic plate without a structure supporting the ballistic plate, whereas the present invention provides the ballistic plate 20 and the ballistic plate as one surface of the ballistic plate body 11. The opposing side includes the bulletproof plate load distribution unit 12, so that the structure is uneven.

The bulletproof plate load distribution unit 12 basically supports the bottom of the bulletproof plate 20, and thus, receives the load from the bulletproof plate 20 and transmits the load to the ballistic plate body 11 to disperse it.

In addition, the bulletproof plate load distribution unit 12 supports the bottom of the bulletproof plate 20 and also supports both left and right sides of the bulletproof plate 20 (grooves or jaws), and prevents the left and right movement of the bulletproof plate 20 Prevents discomfort caused by the left and right shaking of the bulletproof plate 20.

In addition, the bulletproof plate load distribution unit 12 supports the bottom of the bulletproof plate 20 or supports the bottom of the bulletproof plate 20 and both left and right, while also supporting the upper part of the bulletproof plate 20 (groove or jaw), By preventing the bulletproof plate 20 from moving up and down, inconvenience caused by shaking up and down is eliminated.

The ballistic plate body 11 has a size and curvature surrounding the body in order to protect most of the wearer's body, whereas the bulletproof plate 20 protects only key important parts such as the heart, and has a different curvature than the ballistic plate body 11 Thus, the bulletproof plate load distribution unit 12 is formed in the ballistic plate body 11 but is formed according to the curvature of the bulletproof plate 20.

That is, as shown in FIG. 4, the inner surface of the bulletproof plate load distribution unit 12, that is, the front surface of the ballistic plate body 11 is formed with the same curvature as the rear surface of the bulletproof plate 20.

In this structure, the depth of the bulletproof plate load distribution unit 12 may vary depending on the curvature of the ballistic plate body 11 and the bulletproof plate 20, and FIG. 4 shows that the circumference of the bulletproof plate 20 is in the ballistic plate body 11 It is shown as the protruding depth.

As shown in Fig. 5, the ballistic plate 10 of the present invention is divided into a front ballistic plate 10-1 for protecting the chest of the wearer and a rear ballistic plate 10-2 for protecting the back. In this case, the ballistic plate 10 Is divided into a front ballistic plate 20-1 and a rear ballistic plate 20-2, and may be applied to the front ballistic plate 10-1 and the rear ballistic plate 10-2, respectively, but is not limited thereto and It is possible that the front ballistic plate 20-1 is not applied to the ballistic plate 10-2 but only the front ballistic plate 10-1.

Accordingly, in the rear ballistic plate 10-2, the aforementioned bulletproof plate load distribution unit is formed only when the rear ballistic plate 20-2 is applied.

On the other hand, the present invention also has a structural feature in which the shoulder shoulder portion 15 is configured.

The shoulder attachment portion 15 is a type that covers the wearer's shoulder and has a characteristic of preventing the ballistic plate 10 and the body armor from sagging downward due to a load.

In the drawing, the shoulder attachment portion 15 is shown to be on the rear ballistic plate 10-2, but the present invention is not limited thereto, and the shoulder attachment portion 15 includes the front ballistic plate 10-1 and the rear ballistic plate 10-2. ) Can be formed on more than one side.

Hereinafter, the ballistic plate main body 11 will be described.

The ballistic plate main body 11 is a first embodiment in which a hard amour that protects an important part (a vital part such as a chest) and a soft amour part that protects a part that needs activity is formed together (Fig. 6, Fig. 7), Example 2 (Fig. 8) consisting of only a hard armor unit protecting an important part (a vital part such as a chest), and a hard armor unit.

<Example 1>

As shown in Figs. 6 to 8, the ballistic plate main body 11 according to the present embodiment includes a ballistic plate fabric 13 made of a plurality of fabrics and a shell 14 surrounding the periphery of the ballistic plate fabric 13 ( It is preferably made of a heat-resistant and waterproof bulletproof shell). In FIG. 8, the hatching line between the outer shell 14 and the ballistic plate fabric 13 indicates a space.

The ballistic plate fabric 13 and the outer skin 14 are in a flexible state before the hard armor part is formed, and do not restrict wearing and activities while protecting the joint part.

The ballistic plate fabric 13 is, for example, in the form of a sheet made of polyethylene or in a form in which 4 to 6 aramid fibers are additionally laminated on a polyethylene sheet, and has high defense performance against both bullets, debris, explosives, and swords. It is manufactured to have a hard armor part and a soft armor part through pressing and fusion bonding.

Specifically, in the process of laminating the above-described fabric (polyethylene sheet), a resin (hot melt, etc.) for hardening the fabric is added to the position where the hard armor part is formed. The resin is not applied to the location where the soft armor part is molded. That is, although the hard armor part and the soft armor part are the same fabric, there is a difference in resin.

After applying the resin to the fabric, hot pressure is applied through a press to form a ballistic plate.

1. Conditions for forming the hard armor part.

The heating condition is 60℃~135℃, and the pressurization condition is 140kg/㎠~190kg/㎠ The process time according to heating and pressurization is 10~25 minutes. For example, starting at a temperature of 60℃, the fabric is heated and pressurized at a pressure of 140kg/㎠ to 190kg/㎠, and the temperature is raised to 135℃ (gradually raised according to the process time described above). Stop.

The above-described heating conditions are optimal conditions for process time and product damage prevention, and can be started at a temperature of less than 60℃, but because the preheating time is longer, productivity decreases, and when the temperature exceeds 135℃, the product becomes melted. Destroyed. The pressurizing condition is also a condition for matching the product to the optimum strength without breaking.

The above-described temperature includes a temperature at which the resin is thermally deformed and hardened while bonding fabrics through crosslinking ability, that is, the heating condition varies depending on the melting point of the resin.

Accordingly, a plurality of ballistic plate fabrics are bonded to each other through a heating and pressing process, and external waves are bonded to each other with the ballistic plate fabric, and through this process, a single hard protective body is synthesized out of a simple stacking state.

2. Conditions for forming soft armor part.

The hard armor part and the soft armor part are molded at the same time through one press, and as mentioned above, the pressure and heating conditions are the same, but the hard armor part has the same molding conditions because resin was applied and the soft armor part was not applied. In the unused part, it is molded into a soft armor part.

The soft armor portion is formed to have a width of, for example, about 5 cm from the edge of the ballistic plate body.

In the present invention, the press has a structure suitable for the use of molding the hard armor part, the use of shaping the ballistic plate body, and the use of molding the bulletproof plate load distribution part 12.

As shown in FIG. 6, the hard armor part is seen in a state in which ballistic plate fabrics are stacked in a layered form, rather than a layered structure by crosslinking the ballistic plate fabrics through a resin.

On the other hand, in the state where both sides of the ballistic plate fabric 13 are covered with the shell 14, the hard armor part is formed, and thus, in this process, the shell 14 is also integrated with the ballistic plate fabric 13 in the hard armor part.

In view of the above manufacturing process, the two outer skins 14 are in a state where the edges are not attached, and the edges of the two outer skins 14 must be sealed, and in the present invention, the penetration of water through the outer skins 14 is prevented. The edges of the outer shells 14 are sealed by fusion bonding (high frequency) to seal. That is, water may penetrate through the bar hole when sealing by the bar method, but since the present invention is a barless material, the penetration of water is completely prevented.

The ballistic plate body 11 must be formed in a curved ergonomic shape along the body of the wearer, and this molding can be performed according to the shape of the press.

The outer shell 14 is, for example, an aramid fabric with excellent heat resistance (for example, around 3,000 denier), and any one heat-resistant fabric (aramid The fabric is used as an example) and is waterproof.

Waterproofing of aramid fabric is, for example, a method of impregnating or applying a liquid waterproofing material (rubber, silicone, etc.) on one or two sides of the aramid fabric to form a waterproof layer, attaching a waterproof sheet made of a waterproofing material with an adhesive such as epoxy resin. How to do it is possible.

Such an outer shell 14 prevents deformation due to heat and fundamentally blocks the penetration of moisture into the ballistic plate, thereby preventing a decrease in durability due to moisture and a deterioration in the protective performance of the ballistic plate. In addition, a separate waterproof outer shell is provided. Waterproofing is possible even if it is not used.

The outer shell may be prepared by impregnating the above-described heat-resistant and bullet-proof fabric (aramid fabric, PBO, etc.) in a phenolic resin. The phenolic resin functions to improve waterproof and bulletproof performance together with the heat resistance and bulletproof fabric.

<Example 2>

As shown in Figure 9, the ballistic plate body 11 according to this embodiment is composed of only a hard armor part, the configuration of the hard armor part is the same as the hard armor part of Example 1, and the outer skin is integrally formed when forming the hard armor part. do.

The method of manufacturing the load-distributing ballistic plate of the bulletproof plate according to the present invention is summarized as follows.

1. Lamination of ballistic plate fabric and skin.

The ballistic plate fabric and outer shell are cut in a certain size and shape, the cut outer shell is laid on the floor, and the ballistic plate fabric laminated in multiple sheets is placed on it, and the outer shell is covered and laminated.

2. Ballistic plate molding.

The hard armor part is formed by applying heat and pressure to the laminate of the ballistic plate fabric and the outer shell made in the previous process, and is formed in a curved shape to protect the wearer's body, and in this process, the ballistic plate load distribution part 12 is formed. . When the bulletproof plate load distribution unit 12 has a groove shape, the rear surface of the ballistic plate main body 11 may remain flat or may be formed to be convex back along the shape of the bulletproof plate load distribution unit 12.

3. Sheath sealing.

The edge of the outer shell is sealed by high-frequency fusion.

A bulletproof suit including a load-distributing ballistic plate of the bulletproof plate according to the present invention is composed of a vest-shaped clothing (vest), a ballistic plate 10 and a bulletproof plate 20 accommodated in the clothing.

The vest includes a ballistic plate pocket and a bulletproof plate pocket in which the ballistic plate 10 and the ballistic plate 20 are respectively accommodated.

Ballistic plate 10, as shown in Figure 5, the front ballistic plate 10-1 and the rear ballistic plate 10-2 are each housed in the ballistic plate pockets formed on the front and rear portions of the vest, respectively, bulletproof plate (20) is accommodated in one or more of the front and rear portions of the vest.

In the present invention, after inserting the bulletproof plate 20 into the bulletproof plate pocket, the bulletproof plate 20 is pushed toward the ballistic plate 10 so that the bulletproof plate 20 is supported by the bulletproof plate load distribution unit 12 of the ballistic plate 10.

Therefore, the bulletproof plate 20 is accommodated in the bulletproof plate pocket, but since it is supported by the ballistic plate 10, the load is distributed to the ballistic plate 10 and there is no sag toward the bottom.

On the other hand, the ballistic plate pocket and the bulletproof plate pocket of the bulletproof suit may have a single configuration, i.e., one pocket, and in this case, the bulletproof plate 20 on the ballistic plate 10 does not sandwich the outer shell of the pocket and the bulletproof plate load distribution unit 12 ).
