Abstract

Abstract Embodiments of a safety enhanced motorcycle helmet provide enhanced cushioning to protect sensitive areas of the user's head. In each embodiment, a high density foam material is provided just under the thick outer shell of the helmet. The various embodiments contemplate embedding of various designs of low density foam materials within the high density foam layer. Embodiments include strips of low density foam, low density cylindrical foam plugs, channels formed within the high density foam layer and containing low density foam balls, and low density foam wedge plugs.
