Abstract: A helmet is provided having one or more layers of foam forming a first helmet shell nested inside a second helmet shell. Left and right circular ear openings are positioned on opposing sides of the first helmet shell and on opposing sides of the second helmet shell. A faceguard is attached to the first and second ear opening at opposing sides of the second helmet shell and a right ear hole anchor and a left ear hole anchor, each have an inside surface and an outside surface. One each of the ear hole anchors attach to the first and second circular ear openings of the second helmet shell at their inside surface and a first end of the faceguard attaches to the outside surface of the right ear hole anchor and a second end of the faceguard attaches to the outside surface of the left ear hole anchor.

Abstract: A pressure attenuating helmet is provided including separate plates having a plate thickness, an outer surface, under surface, and adjacent edges. The plates joined along the adjacent edges to the other ones of the plurality of plates, forming a helmet shell. Perforated flanges formed along the under surface at the adjacent edges of the plates, the flanges formed inwardly along a line from the adjacent edge of each of the plates extending in the direction of the thickness of the plates. Perforation in the flanges spaced equidistantly in an array along a long direction of the flanges, enabled to accept sutures and aligned flange-to-flange. A network of elastomer splines shaped and positioned to separate the adjacent plates both along the adjacent edges and the perforated flanges. Sutures through the perforations securing the plates together along the adjacent edges and foam cushions are provided between the plates and a wearers head.
