The present invention relates to the technical field of clothing, and more particularly to a protective headgear and a multifunctional casual protective clothing. The protective headgear consists of a headgear body, an inner headgear, a goggle, breathing valves and a headgear zipper. The multifunctional casual protective clothing includes a piece of clothing and a protective headgear. A collar zipper is arranged on the collar of the clothing, and the collar zipper is connected with the headgear zipper of the headgear. By adopting the protective headgear, the multifunctional casual protective clothing of the present invention can avoid and prevent viruses, dust, smog, wind and snow; and after the protective headgear is removed, it can be used as ordinary casual clothing, with various functions and easy use, the protective headgear is suitable for casual clothing such as a coat, sportswear, down jacket, sweater, overcoat, jacket or leather jacket.

The technology described herein relates to breathable, vented, and insulating garments. More particularly, the technology described herein relates to articles with a plurality of interconnected chambers that are configured to retain a thermally insulating fill material such as down or synthetic fibers. The plurality of interconnected chambers are formed between at least two layers of material and between a plurality of seams. The plurality of seams are configured to join the at least two layers of material together. In one aspect, each seam of the plurality of seams is angularly oriented with respect to an adjacent or neighboring seam of the plurality of seams. One or more openings or perforations may be formed on one or more seams of the plurality of seams forming the plurality of interconnected chambers. The one or more openings may achieve evaporation of moisture and/or air transfer from an interior environment of the garment to an exterior environment.

The present invention is directed toward an article of apparel effective to regulate the temperature of the wearer. In an embodiment, the article of apparel includes a base textile with a thermal regulation membrane. The thermal regulation membrane contains a plurality of system-reactive components selectively engaged heat and/or moisture. In an embodiment, the printed coating includes a cooling agent, a phase change material, and a heat dissipation material. In operation, the article of apparel is effective to delay/diminish the rise in skin temperature (compared to a garment lacking the membrane), increasing wearer comfort.

Cooling suit including legs, torso and arms, which includes outwardly opening hose sleeve in the hip area, inwardly branching gas ducts having several outlet openings. A pressurized gas cylinder for carrying along and connecting outlet hose with coupling piece to this hose sleeve, and which comprises a valve and adjusting wheel for the regulated delivery of expanded gas into these gas ducts. The gas ducts in the upper-body have outflow openings in the area of the lower back, hips, neck area, armpits, arm joints, and sleeves. In the lower-body garment, outflow openings are arranged in the knees and the crotch area. This cooling suit is operated with a dry, compressed gas. The gas flowing from the pressure cylinder is expanded, subsequently cools down and then flows through the gas ducts and cools the body. Perspiration is carried away by the permanent gas supply via the breathable fabric of the suit.

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.

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 lighting apparatus for use as a surgical headlamp is disclosed. A light emitting diode is positioned in a recess within a frustoconical, thermally-conductive heat sink that has a several circumferential ridges to provide a desired surface area for heat transfer. The diode and the heat sink are provided in a housing that also includes a fan for drawing ambient air into the housing to contact the heat sink and exhausting heated air. A lens is snap-fit into a slide that frictionally engages the interior of the housing, allowing a user to adjust the spacing between the light emitting diode and the lens as desired. Personal cooling apparatuses usable with the lighting apparatus are also described. Auxiliary undergown switches are also described as are personal cooling apparatuses.

The compression augmented full-pressure suit system includes a garment configured to protect humans in low to zero atmospheric pressure environments while providing excellent mobility. The suit system includes a specialized compression garment worn over the entirety of the body, with a full pressure suit over that compression garment. The compression garment applies a percentage of the pressure on the human form required for protection in low atmosphere environments. The balance of the pressure that is required comes from pressurization of the full pressure suit. Use of both pressure application methods concurrently enables each component to be greatly simplified in comparison to their configuration when used individually, with the result being greater comfort and performance at a reduced cost.
