Abstract
The forced air helmet heater and defroster system for sport and utility vehicles begins with a small motor driven blower. This blower is mounted or fastened to the vehicle and adapted to draw in cold, fresh air from the exterior of the vehicle and force it through a heat source. The heat source warms or tempers this cold fresh air. Then, depending on system configuration, the air exiting the heat source is either forced to an insulated helmet delivery conduit equipped with a break-away connection on the inlet end and a diffuser on the exit end, or it can first be routed to an optional temperature control junction and then to the insulated helmet delivery conduit. The vehicle rider may then place the delivery conduit's exit diffuser between the interior side of the helmet and their cheek or chin whereby the expelling warm air flushes the helmet's interior thus warming the rider's face and breathing air as well as keeping the rider's face shield and eyeglasses defrosted and fog free.
