A helmet for protecting the head of a user may include at least one liner comprising an inner surface and a lower edge surrounding the inner surface at a helmet opening configured to receive a head of a helmet wearer. At least two coupling points may be located on the inner surface proximal to the lower edge. At least one flexible forehead strap may follow the lower edge of the energy management layer and may be inwardly offset from the inner surface. At least two prongs may be coupled to, and slidably extend between, the flexible forehead strap and the at least two coupling points, respectively. A continuous gap between the inner surface and the flexible forehead strap may be provided by an offset created by the at least two prongs, the at least two prongs flexibly maintaining the offset.

Disclosed herein is a buckle including a plug member and a socket member. The plug member includes a shaft part protruding from one side of a first body, a first magnet inserted into the shaft part, a connection recess formed on the outer face of the shaft part, and at least one guide protrusion formed on the inner wall of the connection recess. The socket member includes a connection protrusion formed on one side of a second body to be inserted into the connection recess, a coupling recess formed in the middle of the connection protrusion so that the shaft part is inserted into the coupling recess, a second magnet inserted into the coupling recess, and at least one guide groove formed in the outer surface of the connection protrusion to guide the guide protrusion.

The invention of the present application relates to an apparatus fixed to the face. Particularly, the present invention relates to an apparatus which is fixed to the face by bringing, in close contact with a specific part of the face, at least one from among a mask, hat, helmet, portable sound equipment, glasses or goggles, eye patch, VR device, chin strap and cosmetic facial mask.

A helmet fit system includes a harness, a first anchor and a second anchor secured to a helmet, a tensioning mechanism, and a cable passing from the mechanism, around the first anchor, through the harness, and around the second anchor. The tensioning mechanism is not secured to any portion of the harness. The harness may define a channel, the cable passing through the channel. The tensioning mechanism is mounted to the outer surface of a helmet on the first side of a plane of symmetry of the helmet such that the cable passes through the helmet.

A combat helmet has a shell made from a ballistic rated material, the shell having an outer surface and an inner surface such that at least a portion of the outer surface is formed as a series of adjoining polygon shaped faceted regions that help distribute any force impacted on such regions across a relatively large portion of the shell. The faceted regions are curvedly contoured, and may extend through to the inner surface of the shell. The faceted regions may cover primarily the crown section of the helmet shell, the lower section, or both.

A chin cup that has a hard outer cup and a soft inner cup that may be removable from the outer cup. The inner cup has a peripheral edge extending beyond the edges of the outer cup. Three strap guides, allow a strap to slide through. A one size fits all design includes a central indentation that extends upward toward a top central portion of the cups as well as a central narrowing longitudinally of the cups. Aligned vent holes in the inner and outer cups let the user's chin breathe. The cups have an arcuate longitudinal arch shape. Various embodiments include a boss and hole design that has buttons or mushroom caps that prevent the separation of the cups when not in use and an overmold one piece chin cup embodiment with the soft inner cup imbedded in the hard outer cup.
