Skydiving helmet with anti-fog system

A skydiving helmet with a fog prevention feature which comprises:

• a helmet body formed with an air-intake hole;
• a transparent lens mounted on the helmet body to protect the face of a skydiver, wherein the lens has an inside surface and an outside surface;
• 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 from the air-intake hole over the inside surface of the lens to prevent fog on the lens during a skydiving event;
• and
• an airflow deflector plate affixed to the helmet body for deflecting air into the helmet from the air-intake hole, the airflow deflector plate defining a centerline bisecting the deflector plate and extending between the air-intake hole and the arc of the exhaust vent with a pair of side vanes formed on the deflector plate to straddle the centerline, wherein the side vanes are angled relative to the centerline to widen toward the exhaust vent with an angle therebetween less than the arc of the exhaust vent and a pair of lateral vanes formed on the deflector plate and angled with the side vanes relative to the centerline wherein the lateral vanes are positioned respectively between a side vane and the centerline to create a plurality of airways oriented on the deflector plate for directing the deflected air against the inside surface of the lens during a skydiving event.

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

• providing a helmet body 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 skydiver, 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, 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 extending through an arc centered on the air-intake hole of the chin portion;
• and
• positioning an airflow deflector plate against the air-intake hole to establish an air-intake vent, the airflow deflector plate defining a centerline bisecting the deflector plate and extending between the air-intake hole and the arc of the exhaust vent with a pair of side vanes formed on the deflector plate to straddle the centerline, wherein the side vanes are angled relative to the centerline to widen toward the exhaust vent with an angle therebetween less than the arc of the exhaust vent and a pair of lateral vanes formed on the deflector plate and angled with the side vanes relative to the centerline wherein the lateral vanes are positioned respectively between a side vane and the centerline to create a plurality of airways oriented on the deflector plate to direct air into the helmet and over the inside surface of the lens from the air-intake hole to the exhaust vent, wherein the air deflector plate includes a 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 the plurality of vanes mounted on the base member to extend between the base member and the chin portion of the helmet body to create the 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 a skydive by the skydiver.
