ABSTRACT:
An conditioning system is shown for a helmet having an impact resistant body with an exterior, an interior which defines a head receiving cavity, a front region and having a back region which is located adjacent a lower edge of the helmet body. A first opening is provided in the helmet body located at the back region of the helmet body adjacent a lower edge thereof which acts as an air intake opening. A blower fan communicates with the air intake passage for drawing air into the intake passage and forcing the air from the back region of the helmet in the direction of the front region thereof. A thermoelectric cooling element is located in the helmet interior in communication with the intake passage downstream of the blower fan. The thermoelectric cooling element has a cold side and a hot side. A DC power source is provided for powering the thermoelectric cooling element. An external heat sink is located on the helmet exterior and is connected to the hot side of the thermoelectric cooling element by means of a second opening in the helmet body. Air passing over the thermoelectric cooling element is cooled and air conditions the head receiving region of the helmet.
