Implementations described herein include surgical helmet assemblies that have a helmet enclosure shaped to encircle a head of a user. The helmet enclosure retains a fan and includes a brow bar portion at a front of the helmet enclosure that is shaped to extend along a brow or a forehead of the user and having a light positioned therein. The helmet enclosure also includes a stabilizer extending downward from the helmet enclosure in front of the ears of a user, a face shield that is transparent and coupleable to at least the brow bar portion, a headband shaped to extend across an occiput region of the user's head, and a surgical garment for covering at least the head and shoulders of a user in use. The brow bar portion includes vents disposed therein to direct airflow pushed through the helmet enclosure from the fan onto the user. The face shield is coupleable to the helmet enclosure by one or more of a hook and loop fastener on the helmet enclosure or the stabilizer and a post protruding from the brow bar portion.

An air-conditioned clothing for use with a helmet which can be used when the helmet is worn as well as when the helmet is not worn, includes a clothing main body, at least one fan, an air blow-out unit, a guide sheet and an attachment unit. The air is made to flow through an air flow path by the at least one fan and the flowing air evaporates sweat coming out from a body to cool the body with heat of evaporation and in a case where the helmet is worn, the air which blows out from the air blow-out unit is guided to the helmet by the guide sheet and taken into the helmet from an air intake which is formed between an inner edge of the helmet and the head of the user in order to circulate the air inside the helmet.

A safety helmet (10), including a rigid outer shell (11) and an inner part (11.1) made to absorb and deaden any impact endured by said helmet, and comprising an inner padding (14c) which provides a canalisation structure (16) for conducting air between said at least one air intake opening (12.1) and said at least one air extraction opening (13.1), characterized in that it comprises a cap (15), which, when the helmet is worn by said person, cooperates with said padding to provide a plurality of air channels at said canalizations of said padding and covers the head of the person at least at the padding itself.

A helmet has a fan forcing air into a ducting channel to provide air circulation within the helmet for distributing the exhaust air over a faceplate linked to the helmet for eliminating moisture and frost from the faceplate's interior surface. A heating element warms the circulating air for warmth in extremely cold weather. A wiper is installed above the faceplate for clearing moisture from the faceplate's surface. The faceplate is coated with a photochromic material for causing the lightening and darkening of the faceplate dependent upon the ambient light. A pair of lights are mounted on the front and rear of the helmet for safety. A pair of audio headphones, a microphone, and a transceiver are mounted within the helmet for communication with a cellular telephone. A battery provides power for powering the fan heating elements, the wiper, and the lights.

A protective mask is provided. A protective head covering for reducing exposure to contamination and infection for a user, comprising a fabric affixed to a perimeter of a frame such that the frame and the fabric enclose the user's face. A face shield housed in the frame. An adjustment apparatus affixed to the frame such that the frame may be reshaped. One or more exterior pores affixed to an exterior of the frame and a filtering mechanism housed within the one or more exterior pores.

A surgical garment for use with a helmet, wherein the garment comprises a shell, a transparent face shield, and an attachment element coupled to the transparent face shield. The garment may be configured to define a barrier between the wearer and the environment. The attachment element configured to removably couple with a coupling member of the helmet, wherein the attachment element and coupling member comprise complementary coupling surfaces. The attachment element comprises a head having a distal surface and a proximal surface, and defining a coupling recess, the coupling recess is defined in the proximal surface of the head. The garment may comprise a first and second attachment element, with the first attachment element being coupled to upper portion of the transparent face shield and the second attachment element being coupled to lower portion of the transparent face shield.

A respirator has a shell that defines a breathable air zone for a user wearing the respirator. An air flow control system for the respirator has an air delivery conduit within the shell of the respirator, a valve member moveable relative to the air delivery conduit and within the shell to vary the amount of air flow through the air delivery conduit, and a valve actuator outside of the shell of the respirator. The valve actuator is manipulatable by a user of the respirator while wearing the respirator to control movement of the valve member.

A personal protection system (30,178,290) including a helmet (32,180) to which a garment (102,236) is mounted. The helmet (32,180) includes an electrically powered assembly such as a fan (92,266,268,272). At least one button (120,134,262,264) for regulating operation of the electrically powered assembly (92,266,268,272) is mounted to the face shield (110,240) of the garment (102,236). The helmet (32,180) includes a detector (85) that is connected to and monitors the state of the button (120,134,262,264). When the button (120,134,262,264) is depressed, the detector (85) sends a signal to a controller (88) that regulates the actuation of the electrically powered assembly. The controller (88) then sets the operating state of the assembly (92,266,268,272) so that the assembly (92,266,268,272) operates in the state desired by the individual wearing the personal protection system (30,178,290) based on the depression of the control button (120,134,262,264).

The inventive Invisible Face Mask apparatus comprises a headgear or headwear such as a cap, helmet, strap or a visor, which is equipped with an air purifying mechanism, such as an air filter, that filters ambient air, and an air blower which generates an airflow pushing the purified air in a downward direction in front of and adjacent to the user's face.

A personal protection system including a helmet worn on the head of a user and a hood removably coupled to the helmet. The hood may comprise a shell, a transparent face shield, and a mounting element configured to removably couple the hood to the helmet. The transparent shield may comprise a first lens and a second lens. The first lens may be coupled to the shell, and the second lens may be coupled to the first lens. The second lens may be coupled to the first lens by one of an adhesive, heat staking or ultra-sonic welding. The hood may also comprise a mounting element configured to center the transparent face shield relative to a light assembly coupled to the helmet such that the light emitted from the light assembly passes through a u-shaped opening or slot defined by the second lens.
