ABSTRACT:
A protective head gear or helmet having a ventilating system for cooling the interior of the helmet. Air inlet and outlet openings in the front and neck portions respectively of the helmet and air passages connected to the openings communicate with the interior of the helmet by means of apertures extending between the helmet interior and the air passages. Flow of air through the interior of the helmet, caused by relatively high pressure at the inlet openings and relatively low pressure or suction at the outlet openings during forward movement of the wearer when operating a vehicle, is controlled by valve mechanism operated from the exterior of the helmet.
