Abstract
An integrated helmet having blunt force trauma protection includes a helmet shell, an inner impact layer and the replaceable impact layer. The helmet shell is preferably fabricated from carbon fiber or a high impact plastic. A plurality of openings are formed through the helmet shell to reduce weight. The inner impact layer is attached to an inside surface of the helmet shell. The inner impact layer includes a plurality of deformable cells, which communicate with each other through a plurality of gas channels. The inner impact layer will not burst upon impact. The plurality of deformable cell chambers are filled with air to allow air to be displaced from one area to another area. The replaceable impact layer is attached to an outside surface of the helmet shell. The replaceable impact layer will burst upon impact.
