Helmet with Anti-Fog System for Skydiving and Snow Skiing

A multi-purpose helmet with a fog prevention feature which comprises:

• a helmet body having an inner surface and an outer surface and formed with an air-intake hole;
• a transparent lens engageable via a quick release mechanism with the helmet body to protect the face of a user, wherein the lens has an inside surface and an outside surface;
• an airflow deflector plate affixed to the helmet body for deflecting air into the helmet from the air-intake hole and for directing the deflected air against the inside surface of the lens during an activity;
• and
• an exhaust vent created by a separation distance between the helmet body and the inside surface of the lens, wherein the exhaust vent is located across the lens and opposite the air-intake hole, and wherein the exhaust vent extends through an arc centered on the air-intake hole to draw air over the inside surface of the lens to prevent fog on the lens during the activity.

A method for manufacturing a multi-purpose helmet with a fog prevention feature which comprises the steps of:

• providing a helmet body having an inner surface and an outer surface and formed with an opening bordered by a helmet rim of the helmet body, wherein the helmet rim is dimensioned to surround the face of a user, and wherein the helmet rim has a forehead portion and a chin portion, with the chin portion being formed with an air-intake hole:
• mounting a transparent lens on the helmet body via a quick release mechanism, wherein the lens has an inside surface and an outside surface, and is mounted on the helmet body to cover the opening to separate the inside surface of the lens from the forehead portion of the rim and to create an exhaust vent therebetween:
• attaching a heating unit to the outer surface of the helmet body for heating the lens and preventing fog, wherein the heating unit includes a plurality of resistive conducting strips formed onto the inner surface of the lens, and wherein the heating unit and the plurality of conducting strips are interconnected by a heating wire positioned on the outer surface of the helmet;
• and
• positioning an airflow deflector plate against the air-intake hole to establish an air-intake vent to direct air into the helmet and over the inside surface of the lens, wherein the air deflector includes a substantially flat base member with a scoop formed thereon and positioned across the air-intake hole to establish an upper air-intake vent and a lower air-intake vent, and with a plurality of vanes mounted on the base member to extend between the base member and the chin portion of the helmet body to create a plurality of airways in the upper air-intake vent for moving air from the air-intake hole and into the helmet body to prevent fog from forming on the inside surface during an activity by the user.
