A helmet can comprise an upper-body and a lower-body nested within the upper-body. An opening can be formed within a front portion of the helmet and disposed between an outer surface of the upper-body and an inner surface of the lower-body. A first magnet can be encased within the upper-body or the lower-body and adjacent the opening. A shield can comprise a shield mount and a second magnet coupled to the shield mount that is sized to fit within the opening and to be releasably coupled to the first magnet. The first magnet and the second magnet can be self-aligned in direct alignment with eyes of a user. A third magnet can be disposed above the first magnet and aligned with the second magnet on an outer surface of the helmet out of sight from eyes of the user.

A helmet comprises a shell defining a shell ventilation aperture and an inner liner securable within the shell. The inner liner defines an inner liner ventilation aperture and a recessed track. A ventilation control includes a slider plate and a boss disposed on the slider plate. The boss is configured to be frictionally retained within the recessed track while providing for the slider plate to be reversibly displaced along the recessed track from a first position in which the slider plate blocks a flow of air through the inner liner ventilation aperture to a second position in which the slider plate permits the flow of air through the inner liner ventilation aperture. The slider plate is configured to be reversibly displaced between the first and second position by a force applied upon a lower surface of the slider plate from within the helmet.

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.

The present invention relates to a helmet including mouth vents. The helmet of the present invention includes: a chin guard 100 having a first fastening portion 110 and a second fastening portion 120; a vent body 200 having a first fastening protrusion 210 protruding toward the chin guard 100 so as to be inserted into and fixed to the first fastening portion 110 and a second fastening protrusion 220 protruding toward the chin guard 100 so as to be inserted into and penetrate the second fastening portion 120; and fixing means 300 detachably coupled with the second fastening protrusion 220 penetrating the second fastening portion 120 to fix the second fastening protrusion 220 to the second fastening portion 120.

A head protection system includes a safety helmet and a fire protection cloth. The safety helmet includes a helmet shell (105) and a holding device (108) to guarantee a distance (A) between a helmet shell inner side (106) and the user head (102). An air path (110) is formed by a plurality of openings (120) of a fastening ring (125) and the distance between the inner side of the helmet shell and the head of the user. The fastening ring is arranged at least in an area of the user forehead of the user. The fire protection cloth has a fastening strap (230) with rigid fastening elements (235) configured to mesh with an opening of the fastening ring to detachably fasten the fire protection cloth to the safety helmet. The rigid fastening elements fill the plurality of openings in the fastened state to close the air path.

A thermoformed protective face shield includes a curved top portion adapted to conform to a curved lower portion of a rigid protective headwear. The face shield further includes a visor portion extending outward from a lower end of the curved top portion, thereby creating a space between the user's face and a face cover portion. The visor portion includes one or more channels formed therein for structural support and/or allowing release of heat and/or moisture from the face cover portion. The face cover portion extends downward from the visor portion and covers and provides protection for the face of a user. A side shield portion extends inwardly from the face cover portion. For shielding the sides of a user's face. Further, a perimeter flange may extend perpendicular to the perimeter of the face shield for providing structural support to the face shield.

A helmet cover that has an outer skin, an impact absorbing material and at least one vent comprising an aperture through the helmet cover is described. A helmet cover vent may be aligned with a vent in a helmet, thereby providing for improved ventilation and cooling, and may be attached to a helmet. A helmet cover vent may be configured as a tapered or flared vent, and may be an, air capture vent. The impact absorbing material may be configured over substantially the entire helmet cover surface, or may cover only a portion of the surface. In one embodiment, the impact absorbing material is configured as a discrete pad that is located where impact is most common, such as on the front, sides, or back of the helmet cover. A discrete pad may be interchangeable, allowing for customizing the type and location of impact absorption on the helmet cover.

A helmet having non-bursting air cells preferably includes a hard helmet shell, an outside air cell impact layer and an inside air cell impact layer. The outside air cell impact layer preferably includes at least one air cell layer and an outside layer of sheet material. Each air cell layer includes a plurality of air cells created between two plastic sheets. The inside air cell impact layer includes the at least one air cell layer. The inside and outside air cell impact layers may be permanently or removably attached to hard helmet shell. A second embodiment of the helmet having non-bursting air cells preferably includes the hard helmet shell, the outside air cell impact layer and an inside air cell inflatable impact layer. The inside air cell inflatable impact layer preferably includes at least one inflatable air cell layer and a check valve.

A head, neck and shoulder protection assembly for protecting the head, neck and shoulders of a user includes a pair of shoulder pads. A helmet, which has a bottom edge defining an opening, is reversibly couplable to the shoulder pads. The bottom edge is substantially complementary to an upper surface of the shoulder pads. The helmet is couplable to the shoulder pads such that the helmet is fixedly positioned relative to the shoulder pads. The opening is configured for insertion of the user's head into the helmet. The helmet is positioned to couple to the pair of shoulder pads, such that movement of the helmet relative to the shoulder pads is restricted. The helmet is dimensionally larger than the head and neck of the user, such that the user has full range of movement of the head and neck of within the helmet without the user's head contacting the helmet.

A helmet comprising and outer liner and an inner liner slidably coupled to an interior surface of the outer liner is disclosed. The outer liner comprises an interior surface and the inner liner comprises an exterior surface. The inner liner is composed of an elastically deformable material. A majority of the interior surface of the outer liner and a majority of the exterior surface of the inner liner are both substantially parallel to a pseudo-spherical surface having a coronal cross section that is circular with a first radius and a sagittal cross section that is circular with a second radius different from the first radius. The inner liner is elastically deformable along the interior surface of the outer liner in response to rotation of the outer liner relative to the inner liner caused by an impact to the helmet.
