Abstract
Abstract A head impact force diversion system utilizes an apertured helmet, a rigid transfer arm, and a vest. The helmet, possessing an opening associated with an elevation which may be pivotable upon the helmet or integral with its surface, and vest are worn in a conventional manner. The rigid transfer arm is mounted and affixed to the vest and extends upward from the mounting, arches near and enters the aperture of the helmet, and terminates underneath the elevation. This system permits the usual range of motion of the head and neck during various activities and protects the head and neck when the helmet receives an impact force.
