BACKGROUND OF THE INVENTION1. Field of the Invention
Certain disclosed embodiments relate generally to armor for protection of personnel and/or vehicles, buildings, etc.
2. Description of the Related Art
Currently known armor includes “hard” and “soft” armor. Hard armor can be made very strong, but may be too rigid for some applications. Soft armor has some advantages, but is generally weaker than hard armor.
SUMMARY OF THE INVENTIONAccording to one embodiment, there is provided soft armor. The soft armor comprises an armor structure having a threat side and an inner side inward of the threat side. The armor structure is formed from soft armor material, and the armor structure is substantially imperforable by rifle fire.
According to another embodiment, there is provided soft armor. The soft armor comprises an armor structure having a threat side and an inner side inward of the threat side. The armor structure is formed from soft armor material, and the armor structure is sufficiently strong to defeat rifle fire.
According to another embodiment, there is provided soft armor. The soft armor comprises an armor structure having a threat side and an inner side inward of the threat side. The armor structure is formed from soft armor material, and the armor structure provides at least NIJ type III ballistic protection.
According to another embodiment, there is provided a soft armor garment. The soft armor garment comprises a torso portion formed from soft armor material and configured to wrap around a torso of a wearer. The torso portion provides at least NIJ type III ballistic protection to at least a portion of the torso against threats from any side of the torso.
According to another embodiment, there is provided a soft armor garment. The soft armor garment comprises a torso portion formed from soft armor material and configured to wrap around a torso of a wearer. The torso portion provides at least NIJ type III ballistic protection to the torso against threats within a 360-degree threat envelope.
Certain objects and advantages of the invention are described herein. Of course, it is to be understood that not necessarily all such objects or advantages may be achieved in accordance with any particular embodiment of the invention. Thus, for example, those skilled in the art will recognize that the invention may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other objects or advantages as may be taught or suggested herein.
All of the embodiments summarized above are intended to be within the scope of the invention herein disclosed. However, despite the foregoing discussion of certain embodiments, only the appended claims (and not the present summary) are intended to define the invention.

Any of the embodiments of the soft armor structures 100, 200, 300, 400, 500, 600 disclosed herein may be employed to construct any of a variety of armored equipment. For example, and of the disclosed armor structures may be employed to construct soft body armor, such as a bulletproof vest. In one embodiment shown in
Alternatively, any of the disclosed armor structures may be employed to construct soft body armor panels which may be sewn into, and/or enclosed in pockets formed in, a vest constructed from other suitable materials or fabrics.
Any of the disclosed armor structures 100, 200, 300, 400, 500, 600 may also be employed to form armor panels for use in vehicles, either on or against the vehicle “skin” or in critical locations like seats, cockpits, fuel tanks, hydraulic lines, ammunition stores, etc. Similarly, any of the disclosed armor structures 100, 200, 300, 400, 500, 600 may be employed to construct helmets or armor panels for buildings.
In constructing the armor structures and/or armored articles disclosed herein, each of the layers of soft armor material may be laser-cut into the desired perimeter shape. The layers may be cut individually or in groups of 2 or more. Laser cutting has proven advantageous in that it prevents fraying of woven soft armor materials as the laser heat tends to “heat-seal” the edges of the cut material. In some embodiments, an infrared laser or a carbon-dioxide laser may be employed.
Either of the stitch patterns shown in
Specifications for various materials discussed above are as set forth in the following tables.
