DETAILED DESCRIPTION OF THE INVENTION

[0052] The combined armor plate 1 is formed by the soft ballistic armor plate 2 and one or several hard armor plates 3 (FIG. 1). The total area of one or each of the several hard armor plates 3 is smaller than the total area of the soft ballistic armor plate 2. The hard armor plate 3 is always arranged in the front part of the combined armor plate 1 and, thus, the soft ballistic armor plate 2 is arranged in the rear part of the combined armor plate 1. In separate embodiments of the invention, the rear part of the combined armor plate 1 comprises a foamed material that is arranged as an additional layer behind the soft ballistic armor plate 2 in order to reduce the traumatic effect caused by intrusion of the striking element.

[0053] According to the invention, the one hard armor plate 3 or several hard armor plates 3 and the soft ballistic armor plate 2 are interconnected such that the firm and one-piece uniform structure is formed in each hard ballistic part 5 formed by these two ballistic armor plates 2 and 3 on the entire area 4 or on several areas 4 of the connection between the soft ballistic armor plate 2 and each of the hard armor plates 3. Therewith, the hard armor plate 3 (or several hard armor plates 3) and the soft ballistic armor plate 2 are connected such that said formed firm and one-piece uniform structure does not have even microscopic gaps, plies, cavities between the layers of the ballistic materials. Therefore, uniform zones are provided on the area of the soft ballistic armor plate 2 being hard ballistic parts 5 (FIG. 1), where regions of the soft ballistic armor plate 2 are reinforced with the hard armor plates 3. Zones of the soft ballistic armor plate 2 that are not reinforced with the hard armor plates 3 are soft ballistic parts 6 (FIG. 1). Owing to the described connection, the hard armor plates 3 gain the increased effective area of the ballistic protection both along the entire area of the hard armor plate 3 and along its edges, while the soft ballistic armor plate 2, in the zones of the newly formed hard ballistic parts 5, gains the enhanced ballistic protection against penetration and against blunt trauma effect owing to formation of the one-piece uniform structure.

[0054] The soft ballistic parts 6 comprised in the combined armor plate 1 have smaller firmness and smaller thickness of the ballistic material than the firmness and thickness of the combined armor plate 1 in the locations of the formed hard ballistic parts 5, where the one-piece uniform structure provided by the soft ballistic armor plate 2 and the hard armor plate 3 is formed. This allows to preserve flexibility, elasticity, and lightness of the entire combined armor plate 1 with its main area represented by the soft ballistic parts 6.

[0055] In separate embodiments of the structure, the firm uniform one-piece structure in the location (or several locations) of the formed hard ballistic part 5 has a straight flat or curved or rounded or multi-radius complex anatomic shape. This allows to make the combined armor plate 1 more ergonomic and convenient for the user.

[0056] Also, in separate embodiments of the structure, in order to ensure protection of one specific region of the human body near the vital organ, the combined armor plate 1 may comprise one or several hard armor plates 3 that are arranged in a single region of the combined armor plate 1. During the manufacturing process, this allows to specify and to select the required protection area of the particular region of the combined armor plate 1 from a small one (with one hard armor plate 3) to an enlarged one (with several hard armor plates 3), while at the same time preserving the flexibility of the entire structure.

[0057] During the manufacturing process, the proposed structure allows to formation different ballistic resistance of the hard ballistic parts 5 in terms of characteristics depending on a purpose and future usage conditions of the combined armor plate 1. This is achieved by selecting different materials of the hard armor plate 3 and the number of their layers to form the hard ballistic parts 5.

[0058] The combined armor plate 1 operates in the following way.

[0059] The proposed structure is intended to increase the ballistic resistance in critical locations, i.e., on the specific region or several regions near vital organs of the human user body, that are reinforced by the hard armor plates 3 at the background of the total area of the soft ballistic armor plate 2 owing to features of the structure. Thus, upon hitting with the striking elements, all areas of the soft ballistic parts 6 of the combined armor plate 1 operate in a standard way as already mentioned and described: they ensure protection against pistol bullets and non-sharp shards having low speed.

[0060] The formed uniform zones in the form of the hard ballistic parts 5, where the specific regions of the soft ballistic armor plate 2 are reinforced with the hard armor plates 3, have the increased effective area of the ballistic protection both along the entire area of the hard armor plate 3 and along its edges. Owing to the uniform connection between the soft armor plate 2 and the hard armor plate 3, a material and physical interrelation between them is increased, and, thus, the protection efficiency and expansion of the effective area (in particular, along the edges) of the hard armor plate 3 are enhanced significantly. It is understood that upon hitting the hard ballistic parts 5 with the high-speed shard-ended bullet or shard, the hard armor plate 3 will firstly operate as an individual armor plate, while at the same time the hard armor plate 3 operates in cooperation with the soft ballistic armor plate 2 utilizing its useful ballistic properties as well. At the same time, the soft ballistic armor plate 2 also possesses certain ballistic protection against penetration as well as against blunt trauma effect in the zones of the hard ballistic parts 5 owing to the formation of the one-piece uniform structure. The soft ballistic armor plate 2 also starts to operate in cooperation with the upper structural hard armor plate 3 utilizing its useful ballistic properties together with its own useful properties.

[0061] Upon the formed hard ballistic parts 5 are hit with the striking element, they ensure: [0062] non-penetration in the region of the main area of the hard ballistic part 5; [0063] non-penetration in the region of the edges of the hard ballistic part 5; [0064] reduction of the blunt trauma effect along the entire area of the hard ballistic part 5.

[0065] The small area of the hard ballistic parts 5 is intended to protect the critical regions of the user body, while the high total area of the soft ballistic armor plate 2 allows to preserve flexibility, elasticity, and relative lightness of the combined armor plate 1.

[0066] Therefore, owing to the combination and integral interconnection of the soft ballistic armor plate 2 and the hard armor plate 3, owing to ratio of their areas, owing to the formed hard ballistic parts 5 having the firm and one-piece uniform structure, owing to the presence of the soft ballistic parts 6 having lower firmness and smaller thickness of the ballistic material than the firmness and thickness of the combined armor plate 1 in the locations of the formed hard ballistic parts 5, the following is achieved: [0067] increasing the ballistic protection against penetration and the blunt trauma effect in specifically selected locations of the combined armor plate, and, thus, in specifically selected vital areas of the human user body; [0068] increasing the effective area of the ballistic protection and resistance of the combined armor plate 1 to penetration and blunt trauma effect in specifically selected locations of the combined armor plate, and, thus, in specifically selected vital areas of the human user body; [0069] preserving flexibility and elasticity of the predominant major part of the armor plate; [0070] preserving usage convenience of the armor plate without any significant increase of its weight.

[0071] Industrial applicability and achievement of the technical effects when using the combined armor plate 1 have been confirmed many times during conduction of experimental tests of the pad in practice.

[0072] Results of conduction of these tests are depicted in photos 1, 2 which show the depth of recesses on models resulting from making shots with the pistol bullet (TT pistol) to the hard ballistic part 5 of the combined armor plate 1, and the depth of the recesses of the blunt trauma is less than 10 mm.

[0073] The exemplary specific industrial embodiment of the proposed invention and its usage are mentioned above as the best exemplary embodiment.

[0074] The claimed combined armor plate meets all the requirements for its use, as well as the commonly accepted safety rules for use of such structures in combat conditions.
