A protective helmet including an outer shell including at least one aperture, an elastomeric diaphragm connected to an inner surface of the outer shell and covering the at least one aperture, an inner shell slidingly connected to the outer shell where the inner shell is spaced apart from the outer shell, and at least one expandable bladder positioned between the outer shell and the inner shell and operatively arranged to displace the elastomeric diaphragm in the at least one aperture of the outer shell.

A helmet assembly includes a face shield and a single, center top mounting arrangement that operatively connects a center top location of the face shield to a center front mount on the helmet. The face shield can be raised and lowered about a pivot axis provided in the mounting arrangement between a tilted up, non-use position and a lowered, deployed position. The mounting arrangement can include a detent and two recesses, wherein the detent engages a first recess at a slightly forwardly displaced position to allow ventilation between the helmet and mandible and the face shield and a second recess at the tilted up, non-use position. The recess and detent engagement can be overcome by easy manual force acting on the face shield to reposition the face shield.

A helmet may include an upper-body comprising a first outer shell coupled to a first energy-absorbing shell formed of expanded polypropylene (EPP), expanded polystyrene (EPS), expanded polyurethane (EPU), or expanded polyolefin (EPO). A lower-body may include a second outer shell coupled to a second energy-absorbing shell formed of EPP, EPS, EPU, or EPO, wherein an upper portion of the lower-body is nested within the upper-body and a lower portion of the lower-body extends to an outer surface of a lower portion of the upper-body. A strap anchor may be disposed between the upper-body and the lower-body, and be sandwiched between the upper-body and the lower-body with the strap anchor being adjacent to, and oriented towards, the lower-body. A strap may be coupled to the fastening device and coupled to the strap anchor for coupling the helmet to a head of a user.

Disclosed herein are sports helmets having modular components. A modular component includes an eyewear adapter that is releasably attachable to the helmet and configured to interface with corresponding eyewear in an orientation that permits a wearer of the helmet to see through the eyewear. The eyewear adapter is configured such that, in use, the eyewear adapter enhances the fit or function of the eyewear relative to the use of the helmet and the eyewear without the eyewear adapter. A modular component includes electronics modules that can be mechanically and electrically coupled to the helmet. A modular component includes other functional modules that affect the aerodynamics of the helmet, the air flow of the helmet, the fit of the helmet, or the look of the helmet.

An augmented-reality helmet which in one embodiment is a full-face motorcycle helmet with a look-down micro-display that projects a virtual image in-line with the helmet's chin bar. In order to accommodate the power requirements, the helmet includes a battery pack mounted at the base of the motorcyclist's skull. A wind turbine charges the batteries. Exhaust from the turbine is then deducted through the helmet to cool the battery pack and/or the motorcyclist's head. The turbine is controllable so that it can operate as a circulating fan to provide ventilation. A digital gyroscope provides a control input to a controller for operating a steerable headlight of the motorcycle to track the rider's head movements; and provides acceleration output to an algorithm that will contact emergency responders if the rider is non-responsive after a collision. A 170 degree rear-view camera is mounted within an aerodynamic fairing on the back of the helmet.

An example face shield includes a face shield lens comprising a locking channel, a face shield shell configured to receive the face shield lens when the face shield is inserted into the face shield shell, and a lens lock configured to move between: a locked position in which the lens lock is configured to engage the locking channel of the face shield to secure the face shield lens to the face shield shell; and an unlocked position in which the lens lock is configured to disengage the locking channel of the face shield to permit insertion of the face shield to the face shield shell and removal of the face shield from the face shield shell.

A facial shield for a protective headgear system includes a polymeric sheet having an upper portion configured to be coupled to a support and a lower portion having a lower extremity, wherein the upper portion includes a first hole, a second hole, and a third hole, each one of the first, second, and third holes laterally spaced from the other two of the first, second, and third holes, and the first hole including a first section having a first hole gap and a second section laterally adjacent the first section and having a second hole gap, wherein the first hole gap of the first hole is greater than or equal to the maximum vertical dimension of a first hook of the support, and wherein the second hole gap of the first hole is greater than a vertical base thickness of a base of the first hook and is less than the maximum vertical dimension of the first hook.

An attachment system for securing a frontal helmet extension to protective headgear, the attachment system including one or more magnetic elements disposed on the helmet and/or frontal helmet extension and one or more complementary elements disposed on the helmet and/or frontal helmet extension and adapted to engage the magnetic elements. The magnetic elements and complementary elements are configured to detachably couple the frontal helmet extension to the helmet in a position wherein the frontal helmet extension extends forward from the helmet. The magnetic properties of the magnetic elements are adapted to magnetically attract the complementary elements so that the frontal helmet extension is effectively secured to the helmet during ordinary use of the helmet while allowing release of the frontal helmet extension from the helmet upon impact.

An integrated helmet and respirator system comprises a shell defining a helmet portion, the helmet portion being bounded by a peripheral edge. An annular shroud has an upper edge and a lower edge, the upper edge removably attached to the peripheral edge of the helmet portion and the lower edge attached to an annular frame member. A front portion of the annular shroud defines a visor. A one-way exhaust valve is received within an opening in the annular frame member. The one-way exhaust valve is configured to allow an exhalation gas exhaled by a user to exit an interior of the integrated helmet and respirator system and to prevent or minimize ambient air from entering the interior of the integrated helmet and respirator system. A neck dam extends downward from the frame and is configured to prevent or minimize ambient air from entering the interior of the integrated helmet and respirator system.

A helmet can comprise an upper-body comprising an upper outer shell and an upper energy-absorbing material coupled the upper outer shell. The helmet can comprise a lower-body comprising a lower outer shell and a lower energy-absorbing material coupled the outer shell, wherein the lower-body is nested within the upper-body. A strap anchor can be formed without a web and embedded within the upper-body or the lower-body between the upper-body and the nested lower-body. A strap can be coupled to the strap anchor, wherein the strap extends between the upper-body and the lower-body and is threaded through the lower-body to couple the helmet to a head of a user. The strap anchor can comprise a size less than or equal to 10-30 millimeters (mm), by 10-50 mm, by 2-10 mm. The strap anchor can be sandwiched between the upper-body and the lower-body and hidden from view within the helmet.
