Benefits of technology

[0010]The unique arrangement and support of tiles allows the armor assembly to assume complex curvatures. The disclosed examples provide the protection of rigid body armor while providing the flexibility and freedom of movement associated with flexible body armor.

Problems solved by technology

Increased weight and reduced flexibility decrease an individual's freedom of movement.
A significant disadvantage with typical arrangements is that a solid plate extending over the majority of an individual's thoracic and abdominal regions tends to be uncomfortable and limits the individual's freedom of movement.
Such arrangements have not proven to be widely accepted or to perform in a manner that has satisfied the needs of the military or law enforcement agencies, for example.

Embodiment Construction

[0025]FIG. 1 shows body armor 20 that can be worn by an individual to protect at least the thoracic and abdominal region of the body. A vest 22 is made of a ballistic material. One example ballistic material has fibers consisting of long molecular chains produced from poly-paraphenylene terephthalamide. One such commercially available material is sold under the trade name KEVLAR. One example includes a vest 22 that is an Outer Tactical Vest used by the military and is known as Inteceptor Body Armor. In the illustrated example, the vest 22 includes a pocket 24 on a front side 26 of the vest 22. A similar pocket (not illustrated) is provided on a rear side 28 of the vest 22.

[0026]An armor assembly 30 is received within the pocket 24. As can be appreciated from FIG. 2, an armor assembly 30 is provided on the front side 26 and the rear side 28 of the example body armor 20. Each armor assembly30 includes a plurality of rigid tiles. This example includes tiles 32, 34, 36 and 38 in a longi...

Abstract

A body armor assembly includes a plurality of rigid tiles that are supported in a manner to provide movement and flexibility while still providing the protection of rigid armor. In a disclosed example, a tile holder maintains a plurality of tiles in a selected alignment. The tile holder maintains a minimum overlap dimension between adjacent tiles. Some of the tiles are maintained by the tile holder in a manner that allows for the overlap dimension to increase beyond the minimum overlap dimension. In a disclosed example, at least two rigid layers have at least one ballistic material layer between them to provide a rigid armor material composition.

Description

FIELD OF THE INVENTION[0001]This invention generally relates to armor. More particularly, this invention relates to multilayer armor that can be incorporated into a flexible body armor assembly, for example.DESCRIPTION OF THE RELATED ART[0002]A variety of configurations of projectile-resistant armor are known. Some are used on vehicles while others are specifically intended to protect an individual. Some materials or material combinations have proven useful for either application.[0003]Body armor for protecting an individual's vital organs, for example, usually comprises a ballistic material. Known materials for such purposes include those sold under the trade names KEVLAR, DYNEEMA, SPECTRA and TWARON. Such ballistic materials typically are fabric-like and provide protection while maintaining flexibility. Multiple layers of such fabrics are known to be useful for body armor that provides protection against low or moderate velocity projectile threats.[0004]One shortcoming of such arr...
