It is a typical harness conformed by a hard outer shell (1) that usually projects a front visor (2), and an optional crown with ventilation ports (3), enclosed in an inner harness (A) that lays on the wearer's head, keeping a considerable clearance in respect of the inner face of the shell (1). The helmet is put on the wearer's head and is positioned using an adjustable annular headband (4). The harness is a crowned thin structure conformed by curved portions of different width and equal thickness, which form stretching deformation portions based on the energy transferred during an impact. Thanks to the sizing of the curved portions that form the crowned structure, stretching deformation occurs at temperatures ranging from −18° C. to 50° C. The crowned structure is shaped from an upper elliptic portion (5) that delimits a vast upper and central opening (6) that is substantially elliptic, from which radial portions extend (7 and 8) until reaching a lower adjustable annular headband. This upper elliptic portion (5) presents two diametrically opposed stretched openings (9 and 10), through which it is subdivided in two internal curved portions of lesser width (11 and 12), opposed to the respective external curved portions, which are wider (13) and (14).

Helmets and methods for manufacturing a helmet are described. An example helmet includes a shell and a shock absorbing liner attached to the shell. The shock absorbing liner includes a cavity. The helmet a shock absorbing insert formed of a material different than the material of the shock absorbing liner. The cavity is configured to retain the shock absorbing insert.

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.

An airborne pathogen extraction system that provides for continuous airborne pathogen particle extraction from a specifically targeted area in a room or a specifically targeted area proximate to a user. The pathogenic particles are filtered and/or disinfected before the air is returned proximate to the originating location, or are directed an area away from the user(s). The airborne pathogen extraction systems and methods lower the chances of contagion or infection from airborne pathogens, such as viruses.

Antivirus helmets and techniques to manufacture the antivirus helmets are provided. The antivirus helmets can protect subjects from viruses, bacteria, or other types of pathogens. The antivirus helmets can be modular and can isolate a subject wearing the antivirus helmets from the surrounding environment. The antivirus helmets can be deformable and can be worn during extended periods while protecting a subject wearing the antivirus helmet and other subjects in the environment surrounding the subject.

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 positive-pressure protective wear has a protective body and an air supply. The protective body has a clothing and a headgear connected with the clothing. The air supply is connected with the protective body and inputs gas into the protective body to keep the protective body under positive pressure, and this can provide an effect of ventilation.
