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.

A head-mounted display system includes a head-mounted display unit and a positioning and stabilising structure structured and arranged to hold the head-mounted display unit in an operational position over a user's face in use. The positioning and stabilising structure includes a rear support structure adapted to contact posterior regions of a user's head and at least one connector structured and arranged to interconnect the rear support structure to the head-mounted display unit. The rear support structure is in the form of a hoop comprising an occipital portion configured and arranged engage the user's head along a portion of the occipital bone adjacent a junction where the neck muscles attach to the occipital bone in use.

An impact attenuating helmet including an outer liner having an inner mating surface, an inner liner positioned under the outer liner and having an outer mating surface configured to be received by the inner mating surface of the outer liner, the inner liner and the outer liner being configured to move relative to each other along a slip plane between outer mating surface of the inner liner and the inner mating surface of the outer liner, and one or more securing attachments, each securing attachment being coupled to the outer liner and being configured to secure the outer liner to the inner liner, each securing attachment comprising a slack element configured to permit a range of movement between the outer liner and the inner liner.

A headband for a protection helmet comprises a strip forming at least a part of a ring around a user's head. An adjustment device adjusts a circumference of the ring. The end of the strip is fixed to an attachment point that is movable with respect to the body of the adjustment device. A rotary actuator is connected to the adjustment device by means of a transmission so that rotation of the rotary actuator results in the attachment point being moved with respect to the body. The transmission comprises a flexible transmission shaft configured to transfer a rotary torque applied on the rotary actuator into a rotary torque applied on the adjustment device to move the attachment point and modify the circumference of the ring. A protection helmet comprises such headband.

Headwear for locating people, such as construction workers, firefighters, mine workers, sandhogs, police officers and military personnel. The headwear is hardhat or helmet that tightly fits on a user's head. The headwear comprised of a LED-light, a built-in WiFi device, and power source. The LED-light provides light to the user. The WiFi device transmits the location of the user.

A helmet for a goalie is described herein. The helmet includes a head protective outer shell, a chin cup support bracket, and a shock membrane. The head protective outer shell defines an interior space. The head protective outer shell includes an exterior portion and in interior portion. The exterior portion includes an exterior lower section and an exterior upper section. The exterior upper section is curved. The interior portion is opposite the exterior portion. The interior portion includes an interior lower section and an interior upper section. The chin cup support bracket is secured to the interior lower section. The chin cup support bracket includes dual arm members configured to interface with a removable chin cup. The shock membrane is coupled with the interior upper section. The shock membrane includes a honeycomb design adapted to match a curvature of the exterior upper section and the interior upper section.

A ballistic armored component attaches to the existing retention straps of common combat helmets and provides protection to the otherwise exposed lower skull and upper neck region. A fabric covering contains a soft armor or hard armor insert, and is mounted by straps or other fasteners to existing straps found in conventional helmets. The armor component may be fabric of aramid fibers, or fabric of ultra high molecular weight polyethylene fibers, or may be fabricated of a rigid plate of ceramic, polymer, or metal. The armored component adds additional protection from ground-level or subterranean munitions, by placing a ballistic shape on the lower skull region (occipital region), providing significant additional ballistic coverage with minimal weight and bulk. The fabric shell may also be connected directly to the helmet shell, to allow the component to withdraw within the helmet when the wearer's neck is flexed rearwardly.
