Garment for protection against high-energy projectiles

The invention relates to an item of clothing for protecting essentials human body parts against high-energy projectiles fired from handguns or handguns, Grenade, mine or similar splinters, in which at least in the area of the particularly endangered body parts of the wearer layered, from the combination of a metal or ceramic plate with single or multi-layer synthetic fabrics or the like. existing deposits are arranged, in particular armored vest.

Clothing used to protect against high-energy projectiles, in particular armored vests, have long been available in numerous configurations but quite different Effectiveness known.

Well-known armored vests are provided with padding, which consists of several layers of synthetic fabric, for example Polyamide. Such pads are generally able to contain soft-core projectiles and projectile fragments. When a projectile hits one of these formed cushion it is subjected to a deformation process as a result of the kinetic energy inherent in it. In doing so, it inevitably increases the area with which it acts on the upholstery.

To protect against hard core ammunition, cushions of the type mentioned have certain natural limits. To this disadvantage

or less bulging of the material due to the residual energy remaining in the projectile or fragment. Like operational experience have taught, this residual energy can still be so great that it causes hematomas, broken ribs or - for example shocking - even causing death.

With a bulletproof vest (DE-Gbm 68 08 297) was not only to improve the comfort of the vest, but also also proposed to absorb the residual kinetic energy of the projectile on a carrier web made of foam to attach existing padding. Another proposal (DE-AS Π 96 100) aims at a multi-layer armored vest Packages of polyamide fabrics glued together

in front of each of these packages a plate made of tough plastic, preferably made of a polycarbonate.

Not least because of the conditions already presented here, neither a foam padding is capable of doing this another protective plate made of polycarbonate, each in connection with upholstery, the problem of destruction to solve the residual kinetic energy of projectiles sustainably.

The object of the present invention is therefore to use suitable Structural and constructive measures to distribute the point-like residual energy of a floor over a larger area, in order to ultimately render them harmless to the person wearing the vest.

For such a task, the knowledge that the arrangement of a non-elastic Body behind the upholstery, in the direction of the person wearing the vest, whose bullet-resistant effect tends towards zero.

The object defined above is achieved according to the invention by a cushioning insert that is assigned to the support and faces the wearer and the residual kinetic energy of the projectile, splinter or the like. By distribution absorbing elastic plate.

In a further useful embodiment of this idea, which carries the proposed invention, there is that which distributes the residual energy Plate alternatively made of a sufficiently thin but tempered steel or of a tough, elastic one Plastic, such as polycarbonate.

The invention proposed in this respect has a number of advantages:

Apart from the fact that already existing protective vests due to the extremely low thickness of the elastic panels with

This can be retrofitted without further ado, wearers of such vests now receive optimal body protection, because by arranging a thin and highly elastic plate made of steel or polycarbonate facing the carrier in addition to the combination of steel plate and padding, which is essential for the vest design, injuries to the wearer, regardless of the degree of severity, are practically excluded in the effective protection area of the vest.

In the drawing, the invention is shown using an exemplary embodiment. The - only - figure shows the arrangement a material combination of front, relatively strong steel plate, synthetic fabric and rear, relatively thin and thus flexurally elastic steel or polycarbonate sheet spatial representation.

the insert is connected to a relatively thin and therefore highly elastic plate 3. As a material for such a plate tempered steel or also plastic based on polycarbonate '' proved to be particularly useful.

Assuming, for example, that a hard core bullet fired at a relatively short distance from a handgun or handgun at a high initial velocity (V ₀ ) penetrates the plate 1 * is then subjected to expansion due to the inherent elasticity of the insert, the kinetic that may still remain is sufficient Projectile energy is no longer released in order to penetrate the thin plate 3 as well.

As a result of its material properties, the plate 3 is only subjected to a relatively small amount of deformation, which is in the form of a relatively blunt and
large-area impression (3a) represents. Such an energy absorption distributed over a relatively large area
practically eliminates injuries to the person wearing the vest.
