A mechanically ventilated headgear assembly for cooling a head of a user includes a hat, which can be positioned on the head of the user. The hat has a plurality of apertures positioned therein proximate to a top thereof to vent the hat. A battery is engaged to the hat. A fan, which is engaged to and positioned within the hat proximate to the top, is operationally engaged to the battery so that the battery is positioned to selectively power the fan. The fan motivates air through the apertures to cool the head of the user.

A headwear with an integrated cooling system which effectively and efficiently cools a user's head and neck. The headwear includes a headwear body, a first fan assembly, a second fan assembly, and a rechargeable battery. The headwear body includes a dome, a bill, and a nape-covering portion. The bill and the nape-covering portion are positioned opposite to each other about a rim of the dome. The first fan assembly and the second fan assembly each include a motorized fan and a cover housing, wherein the motorized fan is mounted within the cover housing. The first fan assembly cools the face of the user and is integrated into the bill. The second fan assembly cools the neck of the user and is integrated into the nape-covering portion. The rechargeable battery supplies electricity to the first fan assembly and the second fan assembly. Additionally, the rechargeable battery is mounted onto the dome.

There is disclosed universal pumper skirt for use with a helmet. The universal pumper skirt is composed of a coif wrapping around a wearer's neck and connected to a helmet. The coif includes an air connection input port on the coif. A wearer can use an air flow unit to pump air through the input port, creating positive air pressure in the coif and helmet that cool the wearer and reduce the intrusion of dust into the helmet. The coif may be removably attached to a motorcycle or motorsport helmet, therefore, a wearer can remove the universal pumper skirt from a helmet or transfer it to a different helmet.

A protective headgear (1) comprising: a protective helmet (20) that defines an interior space (31), that comprises an inward major surface, and that comprises a forward window with a windowpane (27); a head suspension that is connected to the helmet; and an air supply module (50) mounted at least partially within the interior space defined by the helmet, wherein the air supply module comprises central, right lateral, and left lateral trunks (53, 54, 55) that are configured so that when the module is mounted within the interior space defined by the helmet, selected central, left and right areas of the inward major surface of the helmet combine with the central, left lateral and right lateral trunks of the air supply module to respectively define a central air supply passage and left and right lateral air supply passages for delivering air to a wearer of the protective headgear, and, wherein the air supply module comprises an external, remote handle (70) that is remotely connected to an air valve that is operative to control a rate at which air is directed into the central air supply passage in comparison to a rate at which air is directed into the left and right lateral air supply passages.

A magnetic quick connect for a fluid delivery system includes a male coupling member and a female coupling member. The male coupling member defines a first outer fluid communication path and includes a first magnetic material. A first inner member is disposed within the first outer fluid communication path and defines a first inner communication path. The female coupling member defines a second outer fluid communication path and includes a second magnetic material. A second inner member is disposed within the second outer fluid communication path and defines a second inner communication path. The male and female coupling members are detachably held together by an attractive force between the first and second magnetic materials such that the first and second outer communication paths are held in fluid communication, and the first and second inner communication paths are held in fluid communication.

A cooling device for attachment to a helmet includes a fan and an electronics assembly. The fan is operable to draw external air into the cooling device. The electronics assembly is operable to control the rotation speed of the fan based on a speed of movement of a user wearing the helmet with the cooling device attached to the helmet. The cooling device additionally includes an air filter, and a deflector to direct cooled air to a desired one of different regions inside the helmet.

An electronic motorcycle helmet. The electronic motorcycle helmet includes a helmet having an aperture therein that can receive a head therethrough. A visor is disposed on a front side of the helmet and a display is disposed on an interior surface of the visor. A microprocessor, including a logic that receives a command input directed to one of a plurality of subsystems, toggles the subsystem between an activated state and a deactivated state, and displays a status window on the display corresponding to the subsystem. The plurality of subsystems includes a plurality of cameras disposed about the helmet, wherein each of the cameras is operably connected to the display and can apply a low-light filter for low-light conditions. Other subsystems include a wireless transmitter to wirelessly communicate with an external device, a GPS system, and a battery disposed at a lower edge of the rear side.

A safety helmet fan system includes a fan housing carrying a fan and configured to be mounted on an exterior of a safety helmet shell above a brim of the safety helmet shell, and an elongate cooling air duct connected to the fan housing to direct cooling air flow from the fan housing around the brim and into an interior of the safety helmet shell. The duct can have a flexible construction that allows the duct to be selectively reshaped to accommodate different safety helmet brim configurations. The duct can have a releasable connector configured to releasably connect the duct to a brim of a safety helmet shell.
