A headgear apparatus for delivering temperature conditioned air including passively or actively cooled, heated, or ventilated air to the interior of a shell is disclosed. A device housing which enshrouds a device for providing temperature conditioned air is placed on a rear portion of the shell. The device housing has air inlets and air rejector vents for delivering fresh air to and removing heated air from the device, and is configured to reduce the heated air from re-entering the device through the air inlets. The headgear apparatus is designed to withstand impact forces without injuring the wearer.

The present disclosure aims for providing a device having an attachment part and an air blowing part so that the device is attachable to the fabric products other than the string. The device provided for solving the above described problem has: an attachment part (622) that is attachable to a fabric product selected from a group consisting of a cloth (620), a shirt (620), a towel (700), a neckerchief (740), a scarf (740), a hood (720), a bandana (720), a fabric product (740) capable of retaining water, and a fabric product (740) storing a water absorptive polymer; and an air blowing part (301) that is supported by the attachment part (622), wherein the air blowing part (301) blows an air flow in a state that the attachment part (622) is supported by the fabric product put on a human body (609).

A pliable padded thermal safety helmet that conforms to a patient's head. The helmet has an exterior layer that protects a patient from impact injuries, and has an interior surface that secures removable thermal packs that provide hot or cold therapy depending on the treatment intended for an injury, infection, etc. The thermal packs are removably attached to the inside surface of the thermal safety helmet, via hook and loop material, at any desired location inside the thermal safety helmet to provide heat or cold to specific areas of a patient's head.

A modular helmet is described herein. The module helmet includes an inner shell adapted to be positioned onto a user's head and an outer shell coupled to the inner shell. The outer shell is spaced a distance radially outward from the inner shell to define a climatic zone between the inner shell and the outer shell. A cooling assembly is positioned within the climatic zone between the inner shell and the outer shell. The cooling assembly includes a plurality of cooling packets that are coupled to the outer shell.

A mechanical refrigeration and heating unit supplies filtered air that is heated or chilled as needed for one or more welding helmets. A portable or transportable cabinet or housing has an air inlet on which a cartridge air filter is mounted. The air passes through an evaporator coil into an evaporator plenum where an evaporator fan moves the air to an outlet that connects with a heater plenum that contains an electric heater module. An outlet of the heater if fitted with an outlet port to which an air hose may be connected. A compressor, condenser coil, receiver, and condenser fan are located in an equipment compartment in the housing. A control board in the unit allows the user to select heated or chilled air. A clogged-filter alarm provides visual and audio alarm signals when pressure in the evaporator plenum falls below a threshold.

A respirator system having a vortex tube with an arcuate hot leg. A respirator helmet has an inlet hose. A vortex tube with an arcuate hot leg and an inlet port is coupled to the respirator helmet. A compressed air source is coupled to the inlet port to supply air to the vortex tube in the range of 110 liter/minute (l/min) to 425 l/min and in the range of 40 pounds per square inch (psi) and 80 psi. This portable arrangement provides effective temperature control within the respirator system.

A safety helmet (100) includes a helmet shell (7), with a bearing support structure (2, 5, 9, 21), with a helmet-side coupling point and with a module adapter (1). The bearing support structure (2, 5, 9, 21) is fastened to the helmet shell (7) on an inside. A helmet-side adapter coupling point of the module adapter (1) can be connected detachably to the safety helmet-side adapter coupling point of the module adapter (1). The module adapter (1) holds a module at the safety helmet (100). A process for fastening a module detachably to a safety helmet (100).

A mask which will provide air purification along with cooling and warming of a wearer's face and mouth, utilizing tubing that is filled with liquid that is detachable to the mask. The liquid is temperature controlled utilizing a thermostat and distributed by a pump. The mask is provided with removable filters, the filters clean incoming air and have filaments of organic herbs that are breathable and can serve medicinal purposes. A fan is attached to the mask to provide air circulation from outside the mask that is filtered before it reaches inside the mask to help purify the incoming air. An exhaust valve filter is placed inside the mask that filters air exiting the mask to the outside environment.

Baseball caps to be worn on a person's head are provided. According to one embodiment, a baseball cap includes a dome configured to be placed on the wearer's head, wherein the dome includes one or more panels and one or more cooling channels. The baseball cap also includes a hub positioned at a top of the dome. The hub comprises a central cavity and one or more conduits in gaseous communication with the one or more cooling channels of the dome. A coolant output port is provided in gaseous communication with the central cavity of the hub. The coolant output port is configured to supply a coolant gas to the one or more cooling channels of the dome via the central cavity of the hub.

An all-weather comfort-control suit operable to permit a rider of an open-air vehicle to heat or cool their body to a comfortable level. The suit may comprise a number of independent temperature zones that may be heated or cooled based upon different conditions specified by the rider and in response to temperatures measured by a number of temperature sensors. The suit may comprise a modular design permitting riders to selectively utilize individual pieces of attire that are desired. The suit may further provide protection to the rider from injury or the environment.
