Abstract: A method and apparatus for construction of a protective head covering (helmet) to be worn by individuals engaged in activity that may, without the apparatus, cause concussive brain injury. The helmet, which is comparable in weight and envelope to conventional helmets, can be constructed from commercially available materials.

A second more rigid inner shell defines a space where one or more compartmentalized sealed elastomer energy absorbing cells are located. These cells contain either a gas or liquid agent designed to adaptively convert potentially injurious normal impact force energy to energy that is channeled between the shells and therefore harmless to the wearer. A portion of this converted energy will be stored and then utilized to automatically re-set the apparatus for the next impact event.
