摘要

A helmet having blunt force trauma protection includes a prior art helmet and a replaceable impact layer. The replaceable impact layer preferably includes at least one gas cell layer, a removable attachment system and an outer layer of sheet material. The at least one gas cell layer includes a plurality of gas cells created between two plastic sheets. Each cell will burst upon a pre-determined impact. The plurality of cells preferably have a hexagon shape, but other shapes may also be used, such as round or square. The removable attachment system is preferably hook and loop fasteners, but other suitable removable attachment systems may also be used. At least one first pad of hook and loop fasteners is attached to an exterior surface of a prior art helmet and at least one second pad of hook and loop fasteners is attached to a bottom surface of the replaceable impact layer.
