A closed face motorcycle helmet includes a shell with an eyeport and a shield attached for hinged motion between a closed position covering and sealing the eyeport and an open position displaced above the eyeport. A hinge plate is attached to the shell on each side and includes a socket into which a hub of the shield is rotatably disposed for hinged movement of the shield. A lever assembly having a downwardly extending lever and a hub with two dowels is attached to the bottom of the hinge plate. The lever assembly is manually movable between a central home position, a forwardly rotated shield cracking position, and a rearwardly rotated shield restraining position. A motion plate is attached to a lower edge of the shield and covers the hub and dowels of the lever assembly when the shield is closed. Surfaces on the inside of the motion plate interact with the dowels of the lever assembly to provide multiple precision shield control functions. Specifically, flipping the lever forward cracks the shield slightly open to eliminate fog and flipping it rearwardly applies an additional restraining force to the shield preventing it from being blown open by aerodynamic forces, especially at high speeds. A live beam mechanism with micro detents interacts with a projection on the shield to provide fluid-like operation of the shield and the ability to position the shield at virtually any location between fully closed and fully opened.

A helmet is particularly well suited for cold-weather use. The helmet includes a jaw shield that is detachable from a head portion.

A spring-loaded quick-release tinted shield is controlled by a lever that selectively raises and lowers the tinted shield. An eye shield pivotally connects to the helmet and is disposed in front of the tinted shield. An eye shield heating system on the eye shield electrically connects to the head portion of the helmet to provide electric power to the heating system.

An edge reinforcement for brittle armor plates is described and claimed herein for improving the ballistic performance of the outer peripheral margins of such plates to incoming threat projectiles. Typically, a transparent armor is positioned within a windowed opening of a security structure. Examples of contemplated security structures protected by my shields are civilian light-armored vehicles, military tactical trucks, and combat vehicles. My reinforced armor system deploys a shield of a hardened material, over and outboard of a brittle armor. Typically, this shield is positioned parallel planar to the brittle armor. If desired, my shield may extend slightly beyond the armor plate and mounting apparatuses. Fortuitously, the reinforced brittle armor plate has more strength than that of the central portion, or even exceeds it. Thereby, said plate will not be defeated merely because threat projectiles impact its weaker margins.

The present invention relates to a protective cover system. One embodiment of the present invention relates to a multi-layer protective cover system configured to be disposed over a transparent object. Particular embodiments relate to incorporating the system with electronic devices and articles of eyewear that include transparent objects such as display screens and lenses respectively. Each layer of the system includes a transparent member, an adhesion system, and a removal system. The transparent member is shaped to two dimensionally conform or exceed the dimensions of an exposed outer surface of the transparent object. The adhesion system removably couples the transparent member to the transparent object in a manner that does not significantly affect the transparency of the combination. The removal system allows individual layers to be removed without substantially affecting the remaining layers or the transparency of the system. One particular removal system embodiment includes attaching an outer tab to each of the layers. Each tab may be uniquely positioned along the outer edge of each layer to allow a user to peel away one or more top layers without affecting the layers below. In addition, each tab may be uniquely colored and / or numerically labeled to indicate the sequence of layers. A second embodiment of the invention relates to a method for sequentially removing protective layers from a transparent object as each layer becomes damaged or otherwise less transparent.
