  • the anterior portion (17), or forward facing part, of the shell (12) is preferably positioned so that the peripheral vision of the wearer is not obstructed by the shell (12).
  • the shell (12) and anterior portion (17) thereof are positioned posterior to the wearer's head (5). This arrangement allows for the wearer to turn his or her head as far as possible left or right with their view being minimally obstructed. To achieve this, the shell (12) should be setback from where the wearer's head (5) would normally be positioned if they were looking straight ahead.
  • a portion of the shell (12) can be lined with an impact absorbing material (16), such as a foam (FIG. 2).
  • an impact absorbing material (16) such as a foam (FIG. 2).
  • the foam is vinyl nitrile.
  • the anterior portion (17) of the shell (12) typically forms an arch around the wearer's head (5) and neck (6).
  • these light emitting elements (14) can be strips of individual light emitting elements (14).
  • the whole of the anterior portion (17) of the shell (12), or a majority thereof, can be provided with light emitting elements (14).
  • the light emitting elements (14) will be in the form of light emitting diodes (LEDs), since LEDs can be powered through a battery or a similar low-voltage power source.
  • LEDs light emitting diodes
  • a camera (19) can also be mounted on the shell (12) or formed in conjunction with the anterior portion (17) thereof.
  • the camera (19) can be a still image and/or video camera, which would allow the wearer to take pictures/videos of his or her surroundings.
  • the camera (19) may be a multi -directional camera, which would allow images/videos to be taken in multiple directions from the helmet (1).
  • cooling elements (18) may be integrated into the shell (12) of the helmet (1) or otherwise attached to the shell (2).
  • the cooling elements (18) may be in the form of cooling coils or an evaporator unit.
  • the cooling coils may be part of a personal refrigeration system, which would include a condenser, expansion valve and compressor.
  • the condenser, expansion valve and compressor may be compartmentalized and worn by the user as part of a utility belt or otherwise.
  • one or more of these elements may be positioned on the helmet (1) outside the shell (12).
  • the cooling elements (18) act as a heat pump to transfer heat from inside the helmet (1) to the environment.
  • the helmet (1) further includes a transparent face shield (15) that abuts the breastplate (11) and shell (12), and surrounds the portion of the wearer's head not surrounded by the shell (12).
  • the face shield (15) is connected to both the breastplate (11) and shell (12).
  • the face shield (15) can be connected to the other two elements by methods known to those skilled in the art, such as pressure fitting, with or without, the use of adhesive.

  • Another consideration for the size and shape of the face shield (15) is that the interior space formed by shell (12) and the face shield (15) should allow for the wearer's head to have a full range of motion.
  • the face shield (15) should be made from an shatter resistant material, such as poly(methyl methacrylate), that is transparent to allow the wearer to visualize their surroundings.
  • the face shield (15) may be provided as photochromatic acrylic glass, polycarbonates or plastics. Such photochromatic materials will darken when exposed to light and lighten in low light conditions.

  • the transparent face shield could be tinted to reduce the amount of ambient light that passes through the face shield.
  • the face shield (15) can also include a helmet mounted display, which would allow a computer generated image to be superimposed on the face shield (15). Since the face shield (15) is transparent the computer generated image would be superimposed on a real-world view to form an augmented reality view. In one embodiment, the computer generated image is projected through a partially reflective mirror.
  • Information displayed on the augmented reality helmet mounted display can include environmental readings, such as temperature, particulates in the environment, and warnings of hazards in the environment.

  • air passages (21) are positioned on the breastplate (11), shell (12), face shield (15), or a combination of two or more of these. In some embodiments, the air passages (21) are positioned on the posterior region of the helmet (1). The air passages (21) allow for air from the environment to pass into the helmet (1) and vice-versa. In order to prevent particulate matter from entering the helmet (1), filters may be positioned within the air passages. These filters can be of any type known in the art, including, but not limited to, charcoal or high- efficiency particulate air (HEP A) filters.
  • HEP A high- efficiency particulate air
  • one or more of these air passages (21) could be replaced or modified to transform the helmet (1) into an open or closed circuit self contained breathing apparatus, comprising a high pressure tank, a pressure regulator and inhalation connection at or in conjunction with the air passages (21).
  • the helmet (1) described herein can be used as part of a personal protection system for personnel working in an underground mine.
  • the personal protection system also includes ear protection (22) that protects the wearer's ears from noise emanating from the environment.
  • the ear protection (22) can be standard ear muffs, or, preferably, are noise cancelling headphones. Such noise cancelling headphones can eliminate noise from the environment, and can act as speakers, so the wearer can receive messages from central command or a microprocessor (23) attached to the helmet (1).
  • the ear protection (22) can include a microphone and/or Bluetooth ® technology or some other wireless technology, so information, such as environmental data, can be transmitted from the wearer to another location or vice versa.
