(16) In one embodiment of the present invention, the helmet appliqu assembly 30 further includes one or more connector members secured to the internal surface of the appliqu element 10 and/or 50, 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.

(17) In one embodiment of the present invention, one or more connector members on the internal side of the appliqu element 10 and/or 50 are evenly distributed across the helmet appliqu so as to mate with appropriate mating attachment elements distributed across the helmet. In another embodiment of the present invention, the helmet appliqu element is provided as part of a helmet appliqu 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 appliqu 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 appliqu element. Similarly, such an assembly or kit can include one or more attachment components for attaching external elements to the external side of the appliqu element 10 and/or 50. 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 appliqu element 10 and/or 50.

(18) The appliqu 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 appliqu element 10 and/or 50 of the present invention is semi-rigid and can be stored in stand-alone or stacked fashion.

(19) The present invention thus provides a helmet appliqu assembly including a helmet appliqu 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 appliqu 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 appliqu 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., Cordura) in order to maintain ballistic integrity in wet or sandy environments.

(20) 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.
