Definitions

  • the present invention concerns a multilayered bulletproof device, which can be used both as a device for personal protection, integrated for example in armor worn by a user, and also to protect means of transport such as armor-plated means, aircrafts or suchlike.
  • Multilayered bulletproof devices are known, used to protect users from bullet shots.
  • Multilayered bulletproof devices are also known, usually worn by users to protect them and defining a part of a protective armor.
  • multilayered bulletproof devices are usually coupled with each other to protect the front part of the body, i.e. the sternum, the back part of the body, i.e. the back, and the lateral parts of the body, i.e. the sides.
  • Each of the parts is called the code of an armor and can be articulated with respect to the others so as to allow freedom of movement for the user wearing it.
  • Multilayered bulletproof devices are sized to resist shots from firearms with high-caliber bullets, including AK-47s.
  • Known multilayered bulletproof devices comprise a plurality of plates made of ceramic materials, overlapping each other to cover a determinate surface and one or more layers of fibers, associated with the plates made of ceramic material and located, during use, inside the plates themselves.
  • the ceramic plates are substantially circular in shape, with a diameter of a few centimeters and are disposed partly overlapping each other, to cover a determinate surface zone and to obtain an armor with a scaled weave.
  • the ceramic plates are made of ballistic ceramic, having properties of great mechanical resistance and great resistance to impacts. Following impact with the bullet of a firearm, the ceramic plates break, absorbing the impact energy of the bullet and protecting the user who is wearing it.
  • the ceramic material has a fragile breaking behavior that causes a total or partial crumbling of the plates hit by the bullet.
  • the layers of fibers can be made of Kevlar, and are configured to absorb and contain the impact energy to which the ceramic plates are subjected.
  • a bulletproof device is also known, from DE-A- 10.2011.078.681 , consisting of a ceramic layer, facing toward the outside during use, and suitable to receive a bullet, a metal layer conformed as a plate and facing toward the inside, and an intermediate layer made of metal foam, interposed between the ceramic layer and the metal layer.
  • the ceramic layer has its surface provided with a plurality of protruding portions distributed uniformly, one adjacent to the other, and substantially conformed as a pyramid.
  • the pyramid structure allows to deflect the trajectory of the bullet, making it lose part of its kinetic energy, and therefore allows to reduce the impact on the multilayered bulletproof device.
  • Solutions of multilayered bulletproof devices are also known, from documents DE-A-199.28.370, DE-A-35.37.093 and FR-A-469.915, which comprise a first layer, external during use, made of metal material and shaped so that the surface, facing toward the outside during use and suitable to receive a bullet, is provided with a plurality of protruding portions distributed one adjacent to the other on the first surface.
  • these documents provide that, as well as the first layer, there is also a second layer located adjacent to the first layer, and located on the side of the first layer that is internal during use.
  • the second layer is defined by a plurality of fibers suitable to contain the deformation to which the first layer is usually subjected due to the impact with the bullet.
  • the first layer is defined by a layer of metal sheet, corrugated so as to define protruding portions that develop longitudinally along the whole longitudinal extension of the bulletproof device.
  • This configuration of the first layer is not able to adequately absorb the impact energy of the bullet, in particular, if the latter hits the first layer in a direction substantially parallel to the longitudinal extension of one of the protruding portions.
  • the first layer is obtained by rolling/shaping a metal sheet which, if hit by a bullet, is deformed and its corrugated shape is flattened.
  • the deformation of the first layer allows to obtain an effect of absorbing the energy of the bullet.
  • this solution is inefficient with regard to high-caliber bullets, in which the energies at play are particularly high. Indeed, in this case, the bullet perforates the first layer directly, without causing any absorption of the impact by the deformation of the layer.
  • One purpose of the present invention is to obtain a multilayered bulletproof device able to resist a plurality of impacts in the same surface portion.
  • Another purpose of the present invention is to obtain a multilayered bulletproof device with uniform capacities of resistance in the different directions.
  • Another purpose of the present invention is to obtain a multilayered bulletproof device that allows to protect the user from the impact of bullets fired by high-caliber rifles.
  • Another purpose of the present invention is to obtain a multilayered bulletproof device able to contain the bullet and/or possible fragments that are generated during the impact with the bullet.

  • the mechanical properties of the metal material, and also the particular shape of the protruding portions, confer on the multilayered bulletproof device the capacity to resist a plurality of impacts on the same surface portion.
  • the particular shape of the protruding portions confers on the multilayered bulletproof device a uniform resistance to the impact of a bullet in any direction from which it arrives, unlike in solutions known in the state of the art where the behavior varies greatly according to the different directions.
