Disclosed is a helmet provided with a radar reflector. The helmet includes a helmet body formed in a shape corresponding to a shape of a user head, and the radar reflector mounted on an outer surface of the helmet body to reflect a radar signal transmitted from radar equipment. The radar reflector includes a plurality of reflection units each concaved in a trigonal pyramid shape having one opened surface, each of the plurality of reflection units reflecting the radar signal. Thus, by applying the radar reflector to the helmet of a user aboard an object to be detected by using a radar signal, the radar signal is effectively reflected in bad weather or at night, thereby improving the recognition rate of radar equipment.

Body protection devices, particularly protective helmets are provided, which comprise a shell of plastic material or of fiber-reinforced plastic material, wherein the shell comprises an outer coating layer formed of a polyacrylic or polyepoxide polymeric matrix including graphene fillers. Processes for the production of body protection devices are also provided.

One embodiment of a helmet 10, upon which markers 14 are used to add decorations to the plastic outer shell 12. The ink from the markers 14 dries quickly, and thereafter becomes waterproof and unable to be removed without the use of chemicals or without damaging the plastic outer shell 12 of the helmet 10. The decorations thus applied are able to withstand the expected rigors of sporting activity without being erased. In addition, a solvent based cleaning solution 18 and a means for applying the solvent based cleaning solution 18 to the plastic outer shell 12 of the helmet 10 is used to erase any mistakes in the decorations, or to erase them entirely, thereby allowing the user to re-decorate the helmet 10 whenever they so desire.

Various embodiments of helmets and methods of their manufacture are disclosed. In some embodiments, the helmet includes a helmet shell having a helmet shell edge and/or a mounting location for mounting an accessory to the helmet shell. A material that is adherent to the helmet shell may be sprayed onto the helmet shell edge of the helmet shell to form a trim. Alternatively, the material may be sprayed onto a portion of the helmet shell associated with either a mounting location for mounting an accessory or a position for a mounted accessory.

A helmet may include a helmet body, a fit system, a bezel, and a hardware retainer. The helmet body may have an outer shell and an energy management layer. The bezel may be separate from the outer shell and coupled to the helmet body at the vent opening of the helmet, encircle the vent opening, and have a hardware opening extending through the bezel and an anchor opening in the bezel adjacent the hardware opening. The hardware retainer may be positioned behind and coupled to the bezel. The hardware retainer may include a hardware receiving aperture aligned with the hardware opening and a hardware retainer cover coupled to a rear side of the hardware retainer. The hardware retainer may further include an anchor recess aligned with the anchor opening. The bezel may be in-molded into the energy management layer.

An impact-absorbing coating may provide an impact-absorbing material and an outer skin. The impact-absorbing coating may be applied to an object and may reduce injuries that may be sustained by a user of the object to which the coating is applied. The impact-absorbing material may have a thickness of approximately ⅜″. The outer skin may be provided over the impact-absorbing material and may provide a paintable and decoratable finish.

A helmet, has a shell that includes a first portion and a second portion. The first portion has first, second and third layers. The second layer is positioned between the first layer and the third layer. The second layer is less dense than the first layer and the third layer. The second portion has a plurality of enemy dissipaters. Each of the energy dissipaters has a rod that extends in a spiraling manner from a fixed end to a free end. The rod tapers continuously along its length from the fixed end to the free end so that the fixed end exhibits a larger internal cross sectional area than the free end. The free end is capable of vibrating when the helmet is impacted by an object in order to dissipate impact energy.

One variation of a system for serving augmented visual content to a user includes: a visor including a substrate of a transparent material and a reflective coating applied across the substrate, configured to selectively reflect visible light within a first reflection channel, and configured to transmit wavelengths of visible light outside of the first reflection channel, wherein the first reflection channel spans a first band of wavelengths; a projection system configured to project visual content in a first output channel onto an interior surface of the visor, the first output channel including a first peak-power wavelength of visible light within the first reflection channel and excluding wavelengths of visible light outside the first reflection channel; and a support structure configured to locate the visor on the user's head with the visor in a field of view of the user and configured to locate the projection system relative to the visor.

A flexible, fibrous energy managing composite panel includes multiple flocked energy absorbing material (FEAM) layers separated by dividers. The FEAM layers can be single side or double side and can be fabricated from monofilament fibers having different properties (e.g., length and denier) flocked onto various substrates. The dividers can include sheets, fabrics, films, foam, spacer fabrics to separate the flock fibers in adjacent layers. The composite panels can be processed for breathability and flexibility. Other embodiments include piezoelectric FEAM layers and dividers for electronic sensing applications, and application of composite panels to body armor and the outer shells of helmets.

A method of creating a design on complex curves and irregular contours of a protective helmet, quickly and without having to first disassemble the helmet. A design is transferred to a clear film/acetate, which is then exposed onto a photoresist mask, transferring the design to the photoresist mask. The mask is washed out creating blast-able areas in the design mask. The mask is adhered to an area of the helmet, which is otherwise covered with a sealed protective bag. Sandblasting/abrasive-blasting etches portions of the helmet surface through the blast-able area of the mask. Various colors or other special effects may be painted/applied onto the etched portions of the helmet surface. The protective bag and photoresist mask can be removed, and the painted areas buffed/polished in a final step.
