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 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.

Abstract: A protective helmet for use with motorsports and cycling activities has a head receiving helmet body that includes a head receiving interior, and an exterior having a front surface, a rear surface, and a perimetral lip for defining a forward-facing aperture. A transparent shield member is engageable with the helmet body and is configured to be placeable adjacent to the forward-facing aperture of the helmet body. The shield member includes a perimetral edge that is sized and configured for engaging the perimetral lip of the helmet body. A strap is coupled to the shield and is configured to engage the rear surface of the helmet body. The engagement of the perimetral edge of the shield member with the perimetral lip of the helmet body enables an increasing force exerted against the shield to be exerted against the helmet, rather than directly against the user's face, and resists the intrusion of dust into the interior of the helmet.

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 can be provided. The helmet can include an outer shell, an omnidirectional liner disposed within and coupled to the outer shell and configured to move relative to the outer shell, and a chinstrap coupled to the omnidirectional liner. The chinstrap coupled to the omnidirectional liner can hold a wearer's head to the omnidirectional liner and prevent the chinstrap from applying forces to the wearer while omnidirectional liner moves relative to outer shell. Other embodiments may include a chinguard with a movable chincup.

Abstract: An embodiment 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 includes 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 by a plurality of isolation dampers for omnidirectional movement of the inner liner relative to the outer liner and the outer shell.

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 by a damper array. The damper array may allow for omnidirectional movement of the inner liner relative to the outer liner and the outer shell.
