Abstract:
1. A protective headgear assembly that reduces the impact forces by spreading them laterally and uses air to resist the impact forces and decrease the rate of deceleration of the human head, said headgear assembly comprising of: an energy absorbent layer made of uniformly consistent viscoelastic material in contact with and placed directly on the outside of a rigid shell; a honeycomb layer with hollow cells and perforated walls for air to flow from one cell to another, in contact with and placed over the viscoelastic energy absorbent layer; a cover over such honeycomb layer, made of soft yet resilient material with small perforations that match with the hollow cells, said perforations being smaller than the hollow cell under it, to provide a constricted passage for the trapped air in the hollow cells to escape into the atmosphere upon impact.
