US Patent 11766085 Omnidirectional energy management systems and methods

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 can be provided. The helmet can 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 polymer liner can be coupled to the inner liner and can at least partly separate the outer liner and the inner liner. Pads and dampers can also couple the outer liner and inner liner and provide for and control omnidirectional movement of the liners relative to each other.
