The present invention relates to protective headgear in general, and more particularly to ballistic armor for protecting portions of the wearer's face.
Penetrating head trauma as the result of projectiles striking the head are among the most severe hazards faced by soldiers and police officers. Such injuries are very often fatal, and where not can cause lasting disability. Metal and leather helmets for protection against bladed and lower velocity projectile weapons have been known since ancient times. The Roman legions employed bronze helmets with cheek guards provided with leather padding. In modern times lightweight helmets have been fabricated from ballistic materials such as Kevlar® phenolic resin treated aramid fabric. Most standard issue combat helmets, such as the U.S. Army Personnel Armor System Ground Troops (PASGT) Helmet, cover the top, rear, and sides of the head, but leave the face of the wearer unprotected.
Protection for the face has been provided by a large clear bullet-resistant shield or visor mounted to the helmet shell, or other stiff member which wraps around the face. While good for some applications, this solution can be too heavy and cumbersome for the average infantryman. Some of these devices can keep the wearer from being able to correctly sight his weapon by not allowing him to position his head and face in very close proximity with his rifle. Additionally face armor may cover the entire face with a single protective item. There are numerous times when covering the mouth and nose of a soldier is unacceptable, for instance when eating, drinking, or communicating.
What is needed is face armor that can be mounted to conventional helmets, yet which preserves access to the face as needed for particular tasks.
A specific arrangement of ballistic material shaped to cover portions of the wearer's face is configured to selectively attach to a ballistic helmet. This arrangement protects otherwise exposed areas of the wearer's head. A shape of ballistic material, which may be soft armor, hard armor, or a combination thereof, is attached to each side of the helmet, one right and one left. These shapes cover the sides of the wearer's head, but leave room to avoid interfering with hearing needs and eye protection devices such as goggles. These shapes are held in place by connecting them to the existing helmet shell or to the straps and hardware of the helmet retention system. A removable piece of ballistic material may be used to join the left and right pieces and thereby cover a significant portion of the wearer's face. The ballistic material may be conventional soft armor, i.e., assemblies of ballistic fabric such as those formed from DuPont Kevlar® fibers, fibers of Spectra® ultra high molecular weight polyethylene fibers from Honeywell, or other ballistic material, or hard armor, for example elements fabricated of rigid plates of ceramic, polymer, or metal, or a combination of hard and soft armor.
It is an object of the present invention to provide face armor which readily and easily attaches to helmets already in the field, without modification to the helmets.
It is another object of the present invention to provide face armor which protects a significant portion of the head from projectiles, while allowing normal sighting of a weapon.
It is also an object of the present invention to provide face armor which protects a significant portion of the head from projectiles, while allowing the wearer to talk, drink, and communicate.
Further objects, features and advantages of the invention will be apparent from the following detailed description when taken in conjunction with the accompanying drawings.
Referring more particularly to
The front band 24 may be thermoformed or injection molded plastic, and need not be a ballistic element, because it extends for the most part over the ballistic shell 38 of the helmet 26. The band 24 may be formed of sheet material about ⅛ inches thick. The front band 24 brow segment 42 above the wearer's face is about one-inch tall, and has a rearwardly extending lip 40 which extends rearwardly about ⅜ of an inch, as best shown in
The ballistic protection is provided to the wearer's face by two porkchop-shaped side elements 46, 48 which are affixed to the downwardly extending mounting flanges 28, 30 of the front band 24, for example by two plastic rivets 52 at each side of the front band. As shown in
The side elements 46, 48 are thus spaced opposite each other on either side of the front band, and are thus positioned to protect portions of the face of the wearer of the face armor assembly 20. A T-shaped opening 62 is thus defined in the front of the face armor assembly between the two side elements 46, 48 and beneath the front band 24. An eye opening 64 is defined between the vertical segments 54 and above the horizontal segments 56. The eye opening 64 is preferably sized to allow the wearer of the armor to comfortably wear conventional goggles or other protective eyewear. A central opening 66 is defined below the eye opening 64 and between the forward edges of the two side element horizontal segments 56. This central opening 66 provides the wearer access to his mouth to permit eating and drinking while wearing the face armor.
The side elements 46, 48 are ballistic armor, preferably formed as an assembly of a plurality of layers of ballistic fabric, such as those formed from DuPont Kevlar fibers or of Spectra® ultra high molecular weight polyethylene fibers from Honeywell. It is desirable that the side elements be generally rigid, so that they stay in the desired protective position with respect to the wearer's face. The side elements are approximately one-half inch thick, and are fabricated by cutting multiple layers of the ballistic fabric into the desired shape, and then subjecting the cut fabric layers, which are impregnated with a resin, to high pressures, about 45 tons, and a temperature of about 250 degrees Fahrenheit. The pressure is applied over a form to give the element the desired three-dimensional shape. The resultant element can then be cut on a bandsaw to the desired perimeter, and is preferably coated, for example, with a polyurethane material to protect the edges of the material.
Because the side elements 46, 48, can come repeatedly into contact with the wearer's face, the inwardly facing surfaces of the side elements may have a soft or resilient sheet 68 adhered thereto, for example a rubbery sheet, or a synthetic material such as duPont Hypalon® chlorosulfonated polyethylene.
The face armor assembly 20 may thus be used with conventional helmets, without regard to the helmet retention system of the conventional helmet. It may very rapidly be applied to the helmet, and removed. In an alternative embodiment, not shown, the front band and the side elements can be injection molded of ballistic material such as transparent polycarbonate plastic as a unitary element, to be mounted to a conventional helmet by a similar elastic strap as in the assembly 20. It should be noted that alternatively, the front band may be a strap of webbing held in tension.
An alternative embodiment face armor assembly 70 is shown in
The helmet cover 72 is provided with attachment patches 84 of one part of a two-part hook-and-loop fastener material such as VELCRO® fastener manufactured by Velcro Industries B.V. The attachment patches 84 may be curved strips of material fixed to the outwardly facing surface 86 of the cover on opposite sides of the helmet.
The attachment patches serve to mount two side elements 88, 90 to the helmet cover. Each side element 88, 90 is comprised of a flexible fabric bag 92 or pouch which has an interior compartment 94 formed between an inner sheet 96 and an outer sheet 98 sewn together. A shaped ballistic element 100 is contained within the compartment 94. The ballistic element 100 may be conventional soft armor, for example a multiplicity of layers of ballistic fabric glued together and formed under pressure into the desired shape. The ballistic fabric sheets may also be co-formed with a plastic sheet stiffening layer of nylon, polyethylene, or a thermoplastic material, such as is disclosed in U.S. Pat. No. 6,892,392, the disclosure of which is incorporated by reference herein.
The fabric bag 92 has a wing 102 which extends upwardly from the ballistic element 100, and an attachment patch 104 is sewn to an inwardly facing surface 106 of the inner sheet 96 on the wing. The attachment patch 104 is the other part of the two-part hook-and-loop fastener to mate with the attachment patch 84 on the cover 72. The side elements may thus be removably engaged with the helmet cover.
To restrict the displacement of the side elements with respect to the helmet shell, each side element 88, 90, has a loop 108 defined by a strip of webbing 110 which is sewn to the inner sheet 96 of the fabric bag 92 in the lower forward corner. Each loop 108 is positioned to receive a portion of a front strap 76 which extends downwardly from the helmet assembly. Because the front straps are secured to the wearer's head, the engagement of the ballistic elements with the front straps serves to position the side elements for protection of portions of the face of a person wearing the helmet assembly.
The shape of the side elements 88, 90 where they project from the helmet may be generally similar to the shapes of the side elements 46, 48, of the face armor assembly 20. Thus each side element has a vertical segment and a horizontal segment which extends downwardly and frontwardly, and is preferably curved about a generally vertical axis, so that the side elements wrap around the wearer's face. Each horizontal segment has an upper portion and a lower portion which is recessed inwardly somewhat from the upper portion.
It should be noted that the helmet cover attachment patches 84 may be supplied sewn to a helmet cover, or alternatively, the mounting patches may have a high-strength adhesive backing with a peel-off release layer, thereby allowing the mounting patches to be attached to pre-existing helmet covers in the field. Moreover, the fabric bag, rather then being sewn from sheets of fabric, may be fabricated of compression molded foam pieces on one or both sides of the ballistic element.
An alternative embodiment side element 112 of another alternative embodiment face armor assembly is shown in
The side element 112 has a shaped ballistic element 114 enclosed within a bag, or otherwise surrounded by a protective covering, such as by gluing a piece of fabric 116 to the exterior of the ballistic element, and a cut sheet of rubber-like material 118 to the interior. The fabric 116 and material 118 define a compartment within an enclosure for the ballistic element. The ballistic element 114 is preferably an assembly of layers of ballistic material in soft armor as described above, but may also be a hard armor element. The side element 112 has a vertical segment 122 which extends downwardly and a horizontal segment 124 which extends downwardly and frontwardly. The entire side element 112 is preferably curved about a generally vertical axis, so that the side element wraps around the wearer's face. As with the above embodiments, the side element 112 may be formed such that the horizontal segment has an upper portion and a lower portion which is recessed inwardly somewhat from the upper portion, to conform more closely to the wearer's face and to allow a rifle to be brought closer to a wearer's face.
A flexible strap 126 is fixed to the sheet of material 118. The strap 126 may be a conventional strip of webbing which extends upwardly from the vertical segment of the side element 112. By threading the strap 126 through the adjustment buckle 81 on the helmet shell 38, the side element is connected to the conventional helmet assembly 26 and positioned at the appropriate height with respect to the wearer's face. The side element is configured for mounting to the retention assembly 74 of the conventional helmet. An inverted L-shaped slot 138 is positioned generally in the middle of the sheet 118, and a three-sided slot 140 is positioned above and rearwardly of the inverted L-shaped slot 138, defining a middle segment 154 of the sheet between the L-shaped slot and the three-sided slot. A short securement slot 142 is positioned above and rearward of the three-sided slot 140. A securement tab 144 is sewn to the sheet 118 to extend upwardly from the inverted L-shaped slot 138. The securement tab 144 is a strip of elastic webbing which is folded over and sewn at its far end to define a catch 146. The securement tab 144 may be passed through a central segment 148 of the three-sided slot 140 and out the securement slot 142, such that the catch 146 engages in the securement slot. Two slots 120 are formed in the lower forward corner of the horizontal segment 124 which are spaced from one another to define a loop 128 which receives a portion of a chin strap 80.
To mount the side element 112 to the retention assembly, the chin strap 80 is passed through the three-sided slot 140 and then out through the inverted L-shaped slot 138, over the surface of the sheet 118, and through the loop 128. The side element 112 is positioned such that the front strap 76 extends upwardly through the upper segment 150 of the three-side slot 140, and the nape strap 78 extends rearwardly through the lower segment 152 of the three-sided slot. The securement tab 144 is then engaged in the securement slot 142, which serves to prevent the release of the front strap 76 and the nape strap 78 from the element, and to thereby retain the side element in place. The sheet 118 is attached to the fabric 116 or to the ballistic element in such a way that the sheet is free from the ballistic element where necessary to allow the straps of the retention assembly to pass beneath the sheet 118.
For additional ballistic protection, a front element 130, as shown in
It should be noted that a helmet strap kit could be constructed with the armored portion at time of manufacture and would not require the ability to be “added on” to an existing helmet retention system.
It should be noted that in place of the front band and strap shown in
It is understood that the invention is not limited to the particular construction and arrangement of parts herein illustrated and described, but embraces all such modified forms thereof as come within the scope of the following claims.
