The present subject matter relates generally to ballistic panels, and headwear incorporating ballistic panels.
Firearms are a known hazard to law enforcement officers. In 2016, one hundred and forty-three law enforcement officers died in the line of duty, and sixty-six of these deaths were attributed to lethal gunshot wounds. Law enforcement officers have worn ballistic vests for decades to reduce the risk of lethal gunshot wounds, but ballistic vests have limitations. In particular, ballistic vests protect torsos while leaving other body parts vulnerable to gunshot wounds.
The head is particularly vulnerable to gunshots, and known ballistic vests offer no head protection. Gunshot wounds to the head are associated with high risk of death or grave disability due to irreversible brain tissue damage. Ballistic helmets are available that can reduce head damage from gunshot wounds. However, police departments frequently limit the use of ballistic helmets because they can appear aggressive or militaristic to the public. Thus, ballistic helmets are generally only issued to Special Weapons and Tactics (SWAT) units in police departments. In addition, ballistic helmets can be heavy and cumbersome for constant wear while on duty.
Aspects and advantages of the invention will be set forth in part in the following description, or may be apparent from the description, or may be learned through practice of the invention.
In a first example embodiment, a ballistic garment includes a fabric cap and a plurality of flexible ballistic panels. Each of the plurality of flexible ballistic panels has a bottom edge and an acutely pointed head that is spaced from the bottom head. The acutely pointed head of each of the plurality of flexible ballistic panels is positioned adjacent a top portion of the fabric cap. The bottom edge of each of the plurality of flexible ballistic panels positioned adjacent a bottom portion of the fabric cap. The plurality of flexible ballistic panels includes no less than six flexible ballistic panels.
In a second example embodiment, a ballistic garment includes a fabric cap and a plurality of flexible ballistic panels. Each of the plurality of flexible ballistic panels has a bottom edge and an acutely pointed head that is spaced from the bottom head. The acutely pointed head of each of the plurality of flexible ballistic panels is positioned adjacent a top portion of the fabric cap. The bottom edge of each of the plurality of flexible ballistic panels is positioned adjacent a bottom portion of the fabric cap. Each of the plurality of flexible ballistic panels also has a first side edge and a second side edge. The first and second side edges extend from the bottom edge to the acutely pointed head in each of the plurality of flexible ballistic panel. The first side edge of each of the plurality of flexible ballistic panels is positioned adjacent the second side edge of a respective one of the plurality of flexible ballistic panels such that the plurality of flexible ballistic panels are distributed around an interior of the fabric cap. The plurality of flexible ballistic panels includes no less than six flexible ballistic panels.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following description and appended claims.

Flexible ballistic panel 100 may include one or more ballistic materials, and flexible ballistic panel 100 is configured to protect against assaults with handguns. Flexible ballistic panel 100 and associated headwear may be suitable for extended daily wear. Thus, flexible ballistic panel 100 and associated headwear may be worn by law enforcement officers while executing their daily duties.
As may be seen in
In
Flexible ballistic panel 100 is constructed of a fiber material that is resistant to penetration by projectiles, such as bullets. As an example, flexible ballistic panel 100 may be constructed of or with a fabric having one or more of ultra-high-molecular-weight polyethylene fibers and para-aramid fibers. In certain example embodiments, the ultra-high-molecular-weight polyethylene fibers may be Dyneema® or Spectra® brand fibers, and the para-aramid fibers may be Kevlar® brand fibers. The fiber material within flexible ballistic panel 100 may be more comfortable for extended wear relative to hard armor panels.
Flexible ballistic panel 100 may include multiple layers of strong, ballistic-resistant fibers that engage and deform a projectile in order to spreading a force of the projectile over a larger portion of flexible ballistic panel 100, relative to an undeformed projectile. Flexible ballistic panel 100 can absorb energy from the deforming projectile and stop the projectile before the projectile completely penetrates the flexible ballistic panel 100. In certain example embodiments, flexible ballistic panel 100 may conform to the NIJ Type IIIa standard and thus protect against penetration by the bullets described in such standard. Thus, e.g., flexible ballistic panel 100 may stop .357 SIG and .44 Magnum ammunition fired from longer barrel handguns.
As shown in
Flexible ballistic panel 100 may also be shaped to suitably protect a wearer. For example, first side edge 130 has a first length L1, e.g., between bottom edge 110 and acutely pointed head 120, and second side edge 140 has a second length L2, e.g., between bottom edge 110 and acutely pointed head 120. Bottom edge 110 has a third length L3, e.g., between first and second side edges 130, 140. A ratio of the first length L1 to the second length L2 may be about 18:18.5, and a ratio of the third length L3 to the first length L1 may be about 2:3. As used herein, the term “about” means within ten percent of the stated ratio when used in the context of ratios. As a particular example, the first length L1 may be about eighteen centimeters (18 cm), the second length L2 may be about eighteen and a half centimeters (18.5 cm), and the third length L3 may be about twelve centimeters (12 cm). As used herein, the term “about” means within ten percent of the stated length when used in the context of lengths. Such sizing of flexible ballistic panel 100 may advantageously allow flexible ballistic panel 100 to fit within headwear while providing desirable protection for a wearer.
The bottom edge 110, first side edge 130 and second side edge 140 may also be oriented to suitably protect a wearer. For example, first and second side edges 130, 140 define an angle α, e.g., at or adjacent acutely pointed head 120. Similarly, bottom edge 110 and first side edge 130 define an angle β, e.g., at or adjacent and intersection of bottom edge 110 and first side edge 130, and bottom edge 110 and second side edge 140 define an angle γ, e.g., at or adjacent and intersection of bottom edge 110 and second side edge 140. As a particular example, the angle α may be about fifty degrees (50°), the angle β may be about eighty degrees (80°), and the angle γ may be about eighty degrees (80°). As used herein, the term “about” means within five degrees of the stated angle when used in the context of angles. Such angling of the edges or flexible ballistic panel 100 may advantageously allow flexible ballistic panel 100 to fit within headwear while providing desirable protection for a wearer.
Fabric cap 200 may be constructed to match the appearance of known headwear, such as a baseball cap, a casquette, a combination cap, a boonie hat, a patrol cap, a ranger hat, etc. Thus, e.g., fabric cap 200 may be constructed of various fabric panels stitched together. Fabric cap 200 may include one or more of para-aramid fibers, polyester fibers, cotton fibers, wool fibers, etc. As may be seen from the above, fabric cap 200 may have a covert and unassuming appearance. Thus, fabric cap 200 with flexible ballistic panels 100 may be worn to provide protection from brain damage due to projectiles, such as bullets, while also avoiding the aggressive or militaristic appearance of known helmets.
Flexible ballistic panels 100 are positioned within fabric cap 200. For example, flexible ballistic panels 100 may include no less than six (6) flexible ballistic panels 100. In certain example embodiments, flexible ballistic panels 100 may include exactly six (6) flexible ballistic panels 100. Within fabric cap 200, the acutely pointed head 120 of each flexible ballistic panel 100 is positioned adjacent a top portion 202 of fabric cap 200, and the bottom edge 110 of each flexible ballistic panel 100 is positioned adjacent a bottom portion 204 of fabric cap 200. In addition, the first side edge 130 of each flexible ballistic panel 100 may be positioned at or adjacent the second side edge 140 of an adjacent flexible ballistic panel 100 within fabric cap 200. Thus, e.g., flexible ballistic panels 100 may be distributed in a generally semi-spherical pattern within fabric cap 200. In particular, flexible ballistic panels 100 may be distributed three-hundred and sixty degrees (360°) around an interior 206 of fabric cap 200, e.g., in a plane that is perpendicular to an axis between the top and bottom portions 202, 204 of fabric cap 200. In such a manner, e.g., flexible ballistic panels 100 may be positioned in fabric cap 200 to cover anterior, lateral and posterior skull bones when fabric cap 200 on a wearer.
