## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application claims priority to U.S. Provisional Patent Application 61/527,671, filed Aug. 26, 2011 and entitled “Protective Helmet Appliqué System and Method.”


FIELD OF THE INVENTION
The present invention pertains to armor-enhanced headwear, and more particularly to an armor-enhanced helmet appliqué assembly including a helmet appliqué that is comfortable, balanced, detachable, versatile and which protects the head from projectiles such as ballistic projections.
BACKGROUND AND SUMMARY OF THE INVENTION
Military and law enforcement personnel have employed armor-enhanced clothing in order to protect their bodies from gunfire, shrapnel, explosive devices and other harmful ballistic objects. Such personnel have further employed armor-enhanced helmets in an effort to block ballistic objects from penetrating traditional helmets and producing injury or grave damage to the head of the wearer. However, prior armor-enhanced helmets are typically heavy and awkward to wear, often causing undue neck fatigue and even injury to the wearer.
The present invention provides a helmet appliqué assembly including a helmet appliqué that is lighter weight, and attachable to an existing helmet to cover one or more areas of an otherwise exposed helmet. The appliqué element of the present invention can be suitably relieved in areas where no ballistic protection is required, or where ballistic protection would otherwise impede certain functions of the helmet and the wearer's desired functional capabilities. The appliqué element of the present invention can comprise various types of material, including, for example, ultra high molecular weight polyethylene (UHMWPE), aramid fibers, ceramics, polycarbonate, steel or a combination of two or more such materials. The appliqué assembly of the present invention further includes one or more underside attachment member types for attaching the appliqué to a helmet, and can optionally include one or more external-side attachment or connector members for attaching other articles to the outside of the appliqué element. Accordingly, the appliqué system and/or assembly of the present invention increases the protection level of a helmet in a specific area or areas as a mission or threat dictates by allowing the appliqué element to be donned or doffed as needed, and thereby does not require the additional weight of the appliqué element to be permanent.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE PRESENT INVENTION
As shown in FIG. 1, one embodiment of the helmet appliqué assembly 30 of the present invention includes a helmet appliqué element 10 attached to an underlying helmet 15. The helmet 15 can be provided with various attachments such as a night vision device mount 20 and a rail system 25. The rail system permits the helmet to attach necessary or desirable articles such as lighting, camera or other accessories as is known in the art. The appliqué element 10 is formed and shaped so as to avoid impeding the use and functionality of the night vision device mount 20 and rail system 25, and can further be designed in alternative embodiments to extend further or less in a given direction depending upon the specific underlying helmet involved.
In the embodiment shown in FIG. 1, the ballistic appliqué element 10 of the present invention includes an external surface 12 and an internal surface in between the element 10 and the helmet 15, a front profile edge 13, a rear profile edge 14 and two side profile edges 16, wherein the side profile edges are curved so as to provide relief around edge attachments 25 of the helmet. The front profile edge 13 can be formed so as to provide an opening 17 in a variety of shapes, such as rectangular, square and/or shaped. In the embodiment shown in FIG. 1, the front profile edge 13 is formed so as to provide a substantially U-shaped opening 17 in the appliqué element. The appliqué element 10 can comprise ballistic material hermetically sealed and encapsulated within a fabric material, wherein the ballistic material comprises one or more of: ultra-high molecular weight polyethylene, aramid fibers, ceramics, polycarbonate material, and/or steel as described above.
In one embodiment of the present invention, the helmet appliqué assembly 30 further includes one or more connector members secured to the internal surface of the appliqué element 10, with the connector members being capable of secure engagement with one or more counterpart connector members of the helmet 15. For instance, hook-and-loop type fasteners, straps, snaps and other similar attachment means can be employed. It will be appreciated that the fastener elements can be directly secured to the fabric material described above.
In a specific embodiment, a hook or loop fastener strip, with adhesive on one side and hook or loop fasteners on the other, is adhered to the internal surface of the appliqué element 10, such that the adhesive side is pressed against the internal surface of the appliqué element and the hook or loop side faces outwardly. A counterpart loop or hook strip can be similarly applied to an underlying helmet (such as helmet 15) in order to be able to securely retain the strip affixed to the internal surface of the appliqué element. It will be appreciated that multiple hook or loop strips can be secured to the internal surface of the appliqué element in locations deemed most suitable to create a secure but releasable fit with the underlying helmet. Such an arrangement is illustrated in the embodiments of the present invention shown in FIGS. 2 and 3, wherein the helmet appliqué element 10 includes fasteners 35 secured to the internal surface 32 thereof, and these fasteners 35 are aligned so as to mate with counter fastener elements 40 on the exterior surface 42 of helmet 15. When element 10 is desired to be donned, it can be attached to helmet 15 by aligning fasteners 35 with fasteners 40, and when element 10 is desired to be doffed, it can be lifted with sufficient pressure from helmet 15 in order to overcome the retention strength of the fasteners, thereby allowing element 10 to be removed.
As an alternative to hook or loop strips, the present invention can use other connector member types, such as male or female snap members secured to the internal surface of the appliqué element, and positioned so as to mate with the counterpart female or male snap members on the outer surface of the helmet. As a further alternative, the connector member types can comprise one or more straps that can be secured to the underlying helmet in known fashion.
In the embodiment of the present invention as shown in FIG. 1, the helmet appliqué element 10 is applied to the frontal lobe of the helmet. However, it will be appreciated that the helmet appliqué element 10 can cover different or additional areas of the helmet depending upon intended use and anticipated threat or mission. Further, it will be appreciated that multiple helmet appliqué elements can be employed on the same helmet when desirable.
In one embodiment of the present invention, one or more connector members on the internal side of the appliqué element 10 are evenly distributed across the helmet appliqué so as to mate with appropriate mating attachment elements distributed across the helmet. In another embodiment of the present invention, the helmet appliqué element is provided as part of a helmet appliqué system kit or assembly, wherein the kit includes alternative attachment members for selection and use by the wearer or assembly personnel. Such an assembly can further include elements that can readily be secured to a helmet that may otherwise be incapable of receiving the helmet appliqué element of the present invention. For example, the kit can include, strips of loop-type fasteners with an adhesive substance on one side and loop fasteners on the other, such that the adhesive side can be secured to the helmet, leaving the loop fasteners exposed and available for receiving mating hook fasteners secured to the underside of the helmet appliqué element. Similarly, such an assembly or kit can include one or more attachment components for attaching external elements to the external side of the appliqué element 10. For instance, a loop-type fastener strip with adhesive on one side can be secured to an identification tag via the adhesive side, and the loop-type fastener side can then be exposed for securing to a hook-type fastener on the external side of the appliqué element 10.
The appliqué element of the present invention can be quickly donned and doffed through the use of the attachment components of the present invention. When not in position on a helmet, one embodiment of the appliqué element 10 of the present invention is semi-rigid and can be stored in stand-alone or stacked fashion.
The present invention thus provides a helmet appliqué assembly including a helmet appliqué element that is lighter weight, and attachable to an existing helmet to cover one or more areas of an otherwise exposed helmet. As described above, the present invention can be suitably relieved in areas where no ballistic protection is required, or where ballistic protection would otherwise impede certain functions of the helmet and the wearer's desired functional capabilities. The appliqué element of the present invention can comprise various types of ballistic material, including, for example, ultra high molecular weight polyethylene (UHMWPE), aramid fibers, ceramics, polycarbonate, or a combination of two or more such materials, In one embodiment of the present invention, the appliqué element can be provided in form similar to a “soft armor” product, wherein the ballistic material is hermetically RF heat sealed and encapsulated within a fabric material (e.g., CorduraTM) in order to maintain ballistic integrity in wet or sandy environments.
The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the claims of the application rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
