Patent Application
20150026858
Many variations of blunt force and ballistic impact protectors for the face and jaw have been designed in the past with a common feature of a rigid attachment to a helmet. However, such systems have performance limitations because they diminish the user's field of view, limit mobility in confined spaces, retain heat and moisture, and/or make helmet systems more difficult to don and doff.
Thus, there has gone unmet a need for improved devices, systems and methods that can provide at least one of improved facial or neck protection to first-responder and military personnel likely to be put in harm's way, such as soldiers, law enforcement officers, and firefighters.
The present systems and methods, etc., provide these and/or other advantages.
The devices, systems, and methods, etc., herein provide, in certain aspects, a two-point, adjustable, partially pliable, and releasable tensioning suspension that supports an anti-blunt-force frame connected to a protective helmet. The protective devices herein can be, for example, “sport-level” and “military/law enforcement-level.” As used herein, “sport-level” indicates face protection capable of withstanding the impacts and traumas experienced in sports such as football, hockey and baseball, while “military/law enforcement-level” means law enforcement officers, firefighters, soldiers, sailors, and the like, i.e., personnel who are likely to encounter heavy blunt force impacts such as vehicle crashes, bats, truncheons, thrown rocks and ballistic impacts such as .22 caliber and 9-millimeter and 0.44 magnum bullets as well as fragmentations from anti-personnel devices such as grenades and improvised explosive devices (IEDs). Thus, a military/law enforcement-level protection system herein typically meets or exceeds the 2010 National Institute of Justice (NIJ) Level IIIA helmet standards for the helmets herein, 2010 NIJ IIIA standards for body armor, and the face protection element and ballistic armor meets or exceeds or MIL-DTL-43511D and/or the 2010 NIJ Level I, Level IIA, or Level II body armor standards, as desired.
The anti-blunt-force frame is positioned and balanced on the wearer's face by an impact absorbing face padding system, including a chin strap or cup, which can be padded if desired. One advantage of this design is that it allows the device to be worn closely on a wide variety of face sizes which is advantageous in confined spaces such as inside military vehicles. It also has the benefit of being rapidly removable from the wearer's face in the event that a gas mask must be donned suddenly, or if the wearer's facial area needs medical attention. The close proximity to the face also increases the wearer's field of view and allows for eye protection such as goggles to be easily donned and doffed. Optional embodiments include open frame designs at the mouth area to allow heat and exhaled moisture to dissipate to the outside environment without impedance.
Thus, in one aspect, the present devices, systems, methods, etc., herein include an adjustable facial protection system for a human comprising a crescent-shaped face protection element configured to withstand blunt force impact and a ballistic material element to prevent the penetration of ballistic and fragmentation projectiles at various force levels to meet different ballistic hazards. The systems can also include a protective helmet.
The face protection element comprises a substantially rigid frame having a right side and a left side, which frame can be comprised of multiple adjoined frame elements or a singular frame element or otherwise as desired. The face protection element can further comprise at least one interior impact absorbing contact point, such as a chin cup or cheek pad configured to hold the face protection element in place against a jaw or face of a user. The frame can comprise at least one right side frame attachment point and one side frame attachment point configured to attach the frame to the helmet. Briefly, the attachment points each attach to corresponding elongated connector elements extending from the respective frame attachment point to a corresponding helmet attachment point located on the protective helmet, such that the elongated connector elements depend substantially vertically from the helmet to the face protection element when the face protection element can be connected to the helmet, wherein, for both sides, the elongated connector element can be pliable and resilient so as to securely retain the face protection element on the jaw of a user and in front of the user's face while simultaneously pliably suspending the face protection element from the helmet, and wherein, for both sides, at least one of the elongated connector element, the side attachment point and the helmet attachment point can be structured such that the distance between the face protection element and the helmet can be selectively adjusted such that the helmet can fit a wide variety of different head sizes. In certain embodiments, the adjustment can be from about 1 inch to 2 inches to 3 inches.
In other aspects, the devices, systems, etc., can comprise only certain devices or sub-systems of the complete systems herein, for example the face protection element without the helmet (albeit configured for attachment to the helmet); the extensible elongated connector elements; or, at least the inner layer and rigid frame layer discussed further below configured to attach to the anti-ballistic layer.
In one embodiment, at least one of the elongated connector element, the side attachment point and the helmet attachment point can comprise a quick release mechanism such that at least one side of the face protection element can be quickly released from the helmet in a single motion by a user. Both the right side and the left side of the face protection element can comprise quick release mechanisms to quickly release the entire face protection element from the helmet. The quick release mechanism can be any desired quick release mechanism, such as those described in U.S. Pat. No. 6,490,729 for a different purpose. For example, the quick release mechanism can be a snap, a quick release buckle, a pull-tab, a ratchet, or a pin and hole mechanism. The system can comprise opposed quick release mechanisms (or other configurations, for example where there is a tensioner member that stabilizes the face protection system on the user, such as a neck strap or side/rear helmet straps) and wherein the system further can comprise a single quick release activator operably connected to all attachment points such that activation of the activator simultaneously releases the attachments in a single motion (or all of the quick release mechanisms if there are more than two quick release mechanisms). The activator can be any desired, effective activator, such as a depressable button, pull-tab, or twistable knob.
The helmet attachment points can be located at any suitable location on the helmet. In one embodiment, the helmet attachment points are located at about the temples of a user and on a forward lip of the helmet, i.e., at about the temporal line of the frontal bone of the skull.
Thus, the facial protection systems can be attached to the brim, or two front suspension bolts, or suspension straps, or other suitable attachment points, found on many military-level helmets such as the Combat Vehicle Crewman (CVC) helmet and an Army Combat Helmet (ACH), as well as the Modular Integrated Communications Helmet (MICH), Personnel Armor System for Ground Troops (PASGT), and the Lightweight Helmet (LWH), etc. Moreover, a single facial protection system herein can be adjusted to fit two or more—or all—of these and other different helmet types and sizes, as well as fitting a wide variety of head and facial types and sizes. Thus, the face protection system can be sized and configured to be used with a variety of helmets including at least helmets with or without ear coverage protection.
In certain embodiments, the elongated connector elements extend substantially vertically between the end areas of either side of the face protection element and their respective attachment points on the helmet; the elongated connector elements can be permanently or semi-permanently attached to either the helmet or the face protection element and releasably attached to the other. The elongated connector elements can be comprised of any suitable material (including composites or combination of materials) such as plastics, rubbers, metals, natural fibers, etc., and can comprise, e.g., ratchet strips, friction fits, adjustment holes or detents and at least one of the attachment element of the face protector or the attachment point on the helmet can comprise a ratchet or other adjustment mechanism configured to releasably, selectively ratchet the elongated connector element and hold the connector element in place when a desired size is achieved. The face protection system further can comprise at least one tensioner member such as a horizontal or angled neck strap or side/rear helmet strap(s) configured to extend from one side of the face protection element behind the neck of a user and attach to the other side of the face protection element for added system stability if desired.
The face protection element can comprise a) an inner layer comprising an interior contact point such as a chin strap, cup or pad comprised of an impact protection material and/or cheek pads; b) a substantially rigid frame layer, wherein the frame is strong enough to resist blunt force impacts including for example military-level blunt force impacts; and, c) an optional ballistic armor material layer comprising one or more ballistic armor materials strong enough to resist military-level ballistic projectiles. If desired, the rigid frame layer can also be configured to resist ballistic impacts and projectiles, the ballistic layer can be configured to resist blunt-force impacts, and each can be configured to resist other possible impacts and insults such as attacks by stabbing and/or edged weapons such as knives, bayonets and swords. Thus, in certain aspects, the specifics of the type and form of impacts, attacks, etc., to be protected against can be varied for each of the rigid frame layer and the armor layer.
The layers can be arranged as follows from interior to exterior: the inner impact absorbing suspension padding layer then the substantially rigid frame layer then the optional ballistic armor material layer. The ballistic armor material layer can be soft armor fabric and can be removably attached to at least one of the other two layers, and the inner layer can comprise at least three pads, one for a left cheek of a user, one for the chin cup, and one for a right cheek of a user. The inner layer (and other layers, if desired) can be discontinuous. For example, the pads can be held to each other and to the other layers of the face protection system by at least one strap extending from one side of the face protection system to the other. The pads can be interchangeable sizes to accommodate different face/head sizes, to vary ventilation or protection levels, or for other purposes as desired.
The substantially rigid frame can be fully rigid, and the substantially rigid frame can be ventilated with a plurality of ventilation holes configured to pass substantial amounts of air from the exterior to the user. The ventilation holes can comprise between about 20 percent to 30 percent, at least 50 percent, or at least 80 or 90 or even 95 or more percent of the surface area of the substantially rigid frame. In some embodiments, the rigid frame can be made of any suitable plastic or metal, such as wire. The ventilation holes can, if desired, comprise a filter media or other structure configured to inhibit the passage of unwanted materials to the face, neck, etc., of the user.
In a further aspect, the face protection element can comprise a) an inner layer comprising an interior contact point and b) a substantially rigid frame layer. At least one of the inner layer and the substantially rigid frame layer can comprise at least two ballistic armor material attachment elements configured to releasably retain a ballistic armor material layer as a further layer of the face protection element.
The inner layer can comprise any suitable material such as a crush protection material selected from at least one of an energy dissipating foam, an energy dissipating gel, or an air bladder, as well as hydraulics or suspension systems, etc. The rigid frame layer can be formed of any suitable material such as plastic or metal or metal wire and can be made by injection molding or other manufacturing processes. The ballistic armor material layer can be soft or hard and can be formed of any desired ballistic material, such as Kevlar®, Twaron®, Spectra Shield®, Dyneema®, aramid fibers or ultra high molecular weight polyethylene, thermoplastic elastomers such as polycarbonates such as Lexan®, or other suitable molded polycarbonates, or ceramics.
In some embodiments, upon quick release of one side of the face protection element, the face protection element swings freely and hangs downwardly via the elongated connector element from a forward portion of the helmet.
In still further aspects, the face protection element further can comprise a transparent or optical face shield, or face shield extending upwardly from an upper edge of the face protection element and sized to cover at least a nose and eyes of a user, for example to protect the user from frontal and some angular impacts. The transparent or optical face shield can be releasably attached to the upper edge of the face protection element, including the uppermost edge of the face protection element, or the transparent or optical face shield can be attached to at least a middle portion between an upper edge and a lower edge of the face protection element.
The transparent or optical face shield can be clear or can be tinted gray, yellow, brown or rose or other color(s) as desired. For example, the transparent or optical face shield can be tinted to selectively enhance wavelengths of light most useful for a person firing a ballistic weapon, and the face shield can comprise a UV protective coating. An upper edge of the transparent or optical face shield can be spaced at least about 1 inch, 2 inches, 3 inches, or more from the forward lip of the helmet or abut the front lip of the helmet using a fending standoff element (e.g., a strut that extends from the helmet and holds the transparent or optical face shield a desired distance from the lip of the helmet) when the face protection element can be fully attached to the helmet. This standoff from the front lip of the helmet can provide enhanced ventilation for a user, which can be important not just for comfort but to reduce the likelihood of exhaustion and heat stroke in hot environments. The upper edge can also contact the helmet for improves performance in cold environments. The transparent or optical face shield can also be pivoted on the face protection element so that it can be moved forward and backward relative to the user's face and to the rest of the protection system, for example for purposes of adjustable ventilation, for cleaning, or for permitting access to the user's face or equipment that is behind the transparent or optical face shield, such as the user's goggles or eyes.
The face protection system further can comprise at least one neck or throat protector extending downwardly from the face protection element and sized to cover at least a substantial portion of a neck or throat of a user. The neck or throat protector can be rigidly affixed to the face protection element, and the neck or throat protector can be attached to the face protection system such that the neck protector can move independently of the face protection element. Thus, in certain embodiments, the neck or throat protector can be hinged or dangle from the face protection element and the neck or throat protector can itself be rigid or flexible. In some embodiments, the neck or throat protector is configured to cooperatively work with and interact with throat protection projecting upwardly from body armor worn by a soldier.
In some embodiments, the face protection system can be configured to include or hold one or more of a heads up display, lighting systems, communications systems or a hydration system.
The substantially rigid frame of the face protection system can be configured to be size adjustable to selectively increase or decrease the breadth, radius or width of the substantially rigid frame. For example, the substantially rigid frame can comprise at least two opposing pieces joined in a center region wherein the joint or hinge between the pieces can be expandable to provide the adjustability, or the frame can comprise at least three pieces joined to each other at either side below the cheek of a user. Similarly, the anti-ballistic material of the face protection system can be also adjustable to selectively vary the radius of the anti-ballistic material element.
These and other aspects, features and embodiments are set forth within this application, including the following Detailed Description and attached drawings. In addition, various references are set forth herein; all such references are incorporated herein by reference in their entirety.
Turning first to the exemplary embodiments shown in the Figures,
The elongated connector elements 28 are sufficiently pliable and resilient so as to securely retain the face protection element 4 on the jaw or face of a user 22 and in front of the user's face in all desired directions while simultaneously pliably suspending the face protection element 4 from the protective helmet 8. The elongated connector elements 28 can extend substantially vertically from the end areas 48 of either side of the face protection element 4. In
The face protection element 4 in
The inner layer 56 comprises a crush protection material 82, for example an energy dissipating foam 84 or an energy dissipating gel 86. The inner layer 56 can be discontinuous and the pads are held to each other and to the other layers of the face protection system 2 by at least one pad strap 74 or other coupling mechanism, which as shown extends from one side of the face protection system 2 to the other.
The attachment of the facial protection system 2 to the protective helmet 8 comprises one or more quick release mechanisms 32 such that at least one side of the face protection element 4 can be quickly released in a single motion by a user 22 from the protective helmet 8. The quick release mechanism 32 can be provided on both the right side and left side of the face protection element 4 to quickly release a part of or the entire face protection element 4 from the protective helmet 8, and the quick release mechanisms 32 can be a snap 34 as in
The substantially rigid frame 10 can be ventilated with a plurality of ventilation holes 76 configured to pass substantial amounts of air from the exterior to the user 22. The ventilation holes 76 can comprise between about 20 percent to 30 percent of the surface area 78 of the substantially rigid frame 10 as in
As with certain other embodiments herein ballistic armor material layer 64 comprises a material 66 strong enough to resist a variety of ballistic or fragmentation projectiles. Adjustable facial protection system 2 also comprises a neck protector 112, which is also made of a material 66 strong enough to resist a variety of ballistic and/or fragmentation projectiles. In this embodiment, neck protector 112 can move independently of the face protection element 4 and is sized to cover at least a substantial portion of a neck of a user 22. In addition, the right side quick release mechanism 32 comprises a pin and hole retention and release mechanism 29 while the left side quick release mechanism 32 comprises a detent retention and release mechanism 31.
Turning to a further general discussion of the present systems, methods, such provide, in certain aspects, a two-point, adjustable, partially pliable, and releasable tensioning suspension that supports an anti-blunt-force frame connected to a protective helmet. The frame is positioned and balanced on the wearer's face by an impact absorbing face padding system, including a cupped chin pad. This design allows the device to be worn more closely to a wide variety of face sizes which is advantageous in confined spaces such as inside military vehicles. It also has the benefit of being rapidly removable from the wearer's face in the event that a gas mask must be donned suddenly, or if the wearer's facial area needs medical attention. The close proximity to the face in some embodiments also increases the wearer's field of view and allows for eye protection such as goggles to be easily donned and doffed. Optional applications of the design could include open frame designs at the mouth area to allow heat and exhaled moisture to dissipate to the outside environment without impedance. The present systems and methods comprises methods and compositions
Thus, one of the basic purposes of the systems is to provide: a) ballistic and fragmentation protection and b) blunt force trauma protection in a single device/system/face mask.
As one part of this, the systems, etc., herein comprise a flexible suspension system that is semi-independent of the helmet and thus allowing movement of the facial protection system somewhat independent of the helmet. This flexible suspension system can be provided by the elongated connector elements discussed herein. The flexible suspension system, and/or other elements of facial protection systems herein, can also permit size adjustment of face mask relative to size of head. The facial protection systems can also provide a single detachment activator (e.g., button) that releases both sides/entire face mask (facial protection element) instantly and simultaneously, e.g., to allow access to helmet to attach alternate device such as a gas mask, or to allow access to the face by a medic. In addition, if desired only one of the elongated connector elements can be released so it snaps on/off, so that the face mask can be easily released from the face in the event that a lower threat level is encountered, but still kept in immediate proximity to the face in the event that an increased threat level—especially a sudden, surprising increased threat level such as an ambush—is presented.
The systems typically comprise a 2 point suspension from the helmet to the face mask, and can comprise a neck strap around the back of neck or a side/rear helmet strap. The neck strap, etc., can comprise a quick release to allow mask to be lifted or pivoted forward and up.
The face mask comprises a rigid frame layer, which can provide a “skeleton” maintaining the form and structure of the face mask, which frame may be fully continuous, discontinuous and/or ventilated. The face mask also comprises a ballistic armor material such as soft armor (aramids and others) or hard armor (ceramics and others). This combination provides ballistic and/or fragmentation protection with blunt force protection via impact load distribution over a larger area. Either the ballistic protection element or the rigid frame can be on the outside of the overall face mask.
In some embodiments, the face mask comprises three layers: a) inner layer against face comprising a chin strap, pad and/or cup and an impact absorbing foam or gel, b) an exoskeleton comprising the rigid frame layer (which can be semi-rigid or fully rigid and can have holes in it for ventilation but can be a solid “sheet” structure if desired), and c) an outer layer comprising a ballistic armor material layer. B) and c) can be reversed in order if desired. In some embodiments, the ballistic armor material can be removable from the skeleton; i.e., the face mask can also be layers a) and b) only, but in such instance the layers typically have an option to include layer c), e.g., attachment points for such structure.
In some embodiments, an energy dissipating foam or gel (or similar; i.e., a protective crush-material) is used in the jaw (e.g., maxilla and/or mandible) and face regions, similar to the use of such materials in crash helmets.
The face mask can have the ability to easily remove ballistic fabric layer to create a fully vented blunt force protector only, and the face mask can have an easily adjustable degree of frag protection with varying thickness or coverage of the ballistic armor material. Similarly, the face mask can have varying degrees of coverage/thickness of the rigid, skeleton layer, and can have adjustable and removable degrees of blunt force protection via removable facial and chin pads.
In certain embodiments, a single facial protection system can size-adjusted to fit on any desired helmet, such as both the Combat Vehicle Crewman (CVC) and Army Combat Helmet (ACH). Thus, a single device can be configured for use with a variety of helmets including helmets with ear coverage/protection and helmets without ear coverage/protection (e.g., to provide open space about a user's ears for headphones, ear muffs, etc.).
It can also be possible to release only one side of the facial protection element for quick “swing away” of the mask, allowing quick don and doff. This release can release the entire system below one or both of the elongated connector element(s), or can be of the ballistic fabric layer only, which can assist ventilation while keeping at least some of the overall protection in place.
The devices, systems, etc., herein can, if desired, be integrated into, worn alongside, and/or replace existing helmet suspension systems, e.g., existing chin straps, etc.
The devices, systems, etc., herein can, if desired, integrate a protective lens or transparent or optical face shield thus combining facial protection with eye protection. This can be in addition to or instead of goggles or other eyewear worn by the user. Generally, the lens/face shield extends upward from the forward edge area of the jaw protector of the face mask, in front of goggles (if worn) and the eyes of the user. The upper edge of the optical face shield can be maintained a significant distance such as up to 2 inches or more from the front lip of the helmet, and thus not attach to the helmet, so that ventilation is better. Alternatively, the optical face shield element can abut the front lip of the helmet, for example using a fending standoff element.
The devices, systems, etc., herein can, if desired, comprise interchangeable facial pads as a means of fit and positioning.
The devices, systems, etc., herein can, if desired, comprise an accessory drape for additional neck protection, with or without independent movement of drape relative to the face mask or other elements of the system. The drape typically extends downwardly from the bottom of the front edge of the ballistic material. Typically, the drape can comprise anti-blunt force and/or anti-ballistic properties.
The facial protection systems can, if desired, be configured such that the rigid, skeletal structure has one or more splits or other structures in the middle area, or even in the precise center, to provide enhanced adjustability and thus comfort and range of use. For example, the “split” can comprise a soft, elastic material to provide some protection over the open area, or can be a center region hinge. There can also be other adjustment configurations, such as dual (or more) width adjustment elements located on either side of the face protector.
The ballistic armor material layer such as a ballistic fabric can also be expandable/retractable for sizing. Similarly to the rigid layer, the ballistic armor material layer could comprise a single, or dual (or more) width adjustment elements located on the front or either side of the face protector. In one embodiment, the ballistic armor material layer width adjustment elements can be under a protective rigid layer piece to provide reduced risk of injury.
The facial protection systems can, if desired, comprising a fairly substantial chin cup, typically padded, to help keep the system in place on the face of a user.
The present application is further directed to methods of making the various elements of the systems and apparatus herein, including making the systems and apparatus themselves from such elements, as well as to methods of using the same, including for example applying the facial protection systems to a user's face and/or head, manipulating the various elements of the facial protection systems, and removing partially or completely the facial protection systems from the user's face and/or head, or otherwise as desired.
All terms used herein are used in accordance with their ordinary meanings unless the context or definition clearly indicates otherwise. Also unless expressly indicated otherwise, the use of “or” includes “and” and vice-versa.

Singular forms, including in the claims, such as “a,” “an,” and “the” include the plural reference unless expressly stated, or the context clearly indicates, otherwise.
The scope of the present devices, systems and methods, etc., includes both means plus function and step plus function concepts. However, the claims are not to be interpreted as indicating a “means plus function” relationship unless the word “means” is specifically recited in a claim, and are to be interpreted as indicating a “means plus function” relationship where the word “means” is specifically recited in a claim. Similarly, the claims are not to be interpreted as indicating a “step plus function” relationship unless the word “step” is specifically recited in a claim, and are to be interpreted as indicating a “step plus function” relationship where the word “step” is specifically recited in a claim.
From the foregoing, it will be appreciated that, although specific embodiments have been discussed herein for purposes of illustration, various modifications may be made without deviating from the spirit and scope of the discussion herein. Accordingly, the systems and methods, etc., include such modifications as well as all permutations and combinations of the subject matter set forth herein and are not limited except as by the appended claims or other claim having adequate support in the discussion and FIGS. herein.
