The inner surface can comprise a first slidable finish comprising a first glaze comprising a thickness less than or equal to 2 millimeters (mm). An inner energy management layer can be disposed within the outer energy management layer and further comprise an outer surface oriented towards the outer energy management layer and an inner surface opposite the outer surface. The outer surface can comprise a second slidable finish that directly contacts the first slidable finish. The second slidable finish can comprise a second glaze comprising a thickness less than or equal to 2 mm. A space between the first slidable finish and the second slidable finish can be devoid of a lubricant and devoid of any interstitial slip layer.

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 protection devices are also provided.

An illuminable helmet assembly is disclosed. The helmet assembly may include a helmet body having an outer shell, an energy management layer and a fit system. A light diffuser is coupled to an outer surface of the helmet body, the diffuser having an illumination surface with an outer perimeter and defining a footprint of the illumination surface extending inward from the illumination surface to a center of the helmet body. A light source is positioned adjacent to and in some cases outside of the outer perimeter and the footprint of the illumination surface. The light source is positioned to emit light toward the illumination surface at an acute angle to the illumination surface.

A safety helmet includes an outer shell configured for surrounding a head of a user, and an infrared reflective layer disposed in an interior of the outer shell. The infrared reflective layer is configured for reflecting at a least a portion of incident infrared radiation transmitted through the outer shell. The infrared reflective layer has infrared reflectivity of at least 40%. The safety helmet further may have an evaporative cooling pad positioned within a cavity defined by the inner surface of the outer shell. A method of manufacturing a safety helmet is also disclosed.

A helmet may be worn on a head of a wearer having a shape and a contour. The helmet may have a plurality of layers coupled together including an energy management layer and an outer shell layer disposed over the energy management layer. The plurality of layers are integrally formed with one another, and the energy management layer is configured to absorb and dissipate energy received by the helmet during an impact by an external force. The outer shell layer is configured to disperse and dissipate impact energy from the external force. Each of the plurality of layers has a density and a geometry, and the density or geometry of at least one layer differs from the density or geometry of at least another layer.

The present invention relates to a method for manufacturing and/or treating thermally deformable reflective material, including steps for: providing a base material such as a plate material or a sheet material, arranging on the base material an adhesive layer in the form of a polymerizable monomer mixture, preferably a photoactivatable monomer mixture, positioning reflective particles on the monomer mixture, subjecting the monomer mixture to a curing process for providing a thermoplastic polymer mixture for the purpose of fixing the reflective particles relative to the base material.

An antistatic sport device includes a basic body and a basic element placed at the basic body, made of a running surface layer and side edges. At least one of the side edges forms a contacting surface that can be turned towards the terrain. Between a rear surface of the running surface layer and the basic body, a contacting element made of an electrically conductive material is placed at least in sections. The running surface layer is electrically conductively connected to the contacting element via a discharge path and further the contacting element to the contacting surface formed by the at least one side edge. Further, a sport system has antistatic function and a sport clothing system is for such sport system.

The present invention is a helmet apparatus configured to accommodate multiple impact hits thereafter retaining usability, with the helmet including an outer shell that is divided into a posterior and an anterior portion, further the outer shell is divided into a left and a right portion, the shell is rigid except for a first relatively less rigid portion that is disposed within the posterior portion straddling the left and right portions, and a second relatively less rigid portion disposed within the anterior portion straddling the left and right portions. Further a flexible channel is disposed along a shell major and minor axes, also a series of fluid bladder layers slidably engaged to one another are disposed on the inside of the shell, wherein the first, second, and channel less rigid portions along with the slidable bladders absorb kinetic energy impacts to the shell reducing energy transfer to the user's head.

An exemplary scalable helmet includes a base helmet having a lower edge, a ballistic portion removably attached to the base helmet, and a mounting portion including at least one connector. The mounting portion extends along a portion of the lower edge of the base helmet for connecting an accessory to the scalable helmet. The connector includes at least one restraining portion for restraining movement of the accessory attached to the base helmet. The mounting portion extends below a lower edge of the ballistic portion when the ballistic portion is attached to the base helmet, and the ballistic portion is removable from the base helmet without removing an accessory connected to the connector.
