Omnidirectional energy management systems and methods

Abstract

Systems and methods of a safety helmet for protecting the human head against repetitive impacts, moderate impacts and severe impacts so as to significantly reduce the likelihood of both translational and rotational brain injury and concussions may be provided. The helmet may include an outer shell, an outer liner disposed within and coupled to the outer shell, and an inner liner disposed within and coupled in spaced opposition to the outer liner. A damper array may allow for omnidirectional movement of the inner liner relative to the outer liner and the outer shell.

What is claimed is: 
     
         1 . A helmet comprising:
 an outer shell;   a liner assembly comprising:
 an outer liner disposed within and coupled to the outer shell; and 
 an inner liner disposed within and coupled to the outer liner; and 
   a limit mechanism disposed on the liner assembly and configured to prevent over-rotation and/or over-displacement between the outer liner and the inner liner.
