A mounting rail assembly comprises a rail configured to be coupled to a helmet. The rail may include a rear surface and a front surface with a mounting groove extending along a length of the front surface. The mounting groove may be open outwardly from a front surface of the rail and be configured to couple to a first accessory device at two or more positions along the length of the rail. A recess may be proximate an edge of the mounting rail assembly. The recess may be open generally perpendicular to the mounting groove and configured to receive a second accessory device. At least a portion of the recess may be positioned between the mounting groove and the rear surface of the rail.

Lighted headgear are provided that include removable self-contained light modules. The self-contained light modules can include a housing that contains one or more light sources and a rechargeable power source. The housing may include a protruding engagement portion for removably securing the self-contained light module to a cap portion of the lighted headgear.

An airflow device configured for creating an air barrier includes a fan, a power source, a laminar assembly, and an attachment mechanism. The power source is coupled to the fan. The laminar assembly includes a plurality of tubes and is coupled to the fan so that air flow generated by the fan passes through the plurality of tubes to create the air barrier. The attachment mechanism attaches the laminar assembly to a user in a location near the user's head such that the air barrier created by the laminar assembly is positioned in front of the user's face. A plenum is positioned between the fan and the laminar assembly such that the air flow generated by the fan passes through the plenum and then through the laminar assembly. The airflow device acts as a face shield that protects the user from airborne contaminants and viruses.

A helmet is provided, which includes a helmet shell and a fastening assembly. The fastening assembly has a mounting fixture releasably connected to the helmet shell and a release mechanism operatively connectable to the mounting fixture, where connection of the release mechanism to the mounting fixture secures the mounting fixture to the helmet shell, and disconnection of the release mechanism from the mounting fixture enables disconnection of the mounting fixture from the helmet shell.

A neck cover and a helmet are provided that improve quietness of a helmet interior and that do not cause inconvenience for a wearer. In order to eliminate a gap between an opening portion of a helmet and a neck periphery of a wearer, insert-through holes, which are for passage of a chin strap that is attached to an inner side of the helmet, are formed in a portion, which covers a front portion (throat) of a neck, of a neck cover that is attached to a peripheral edge of the opening portion.
