Abstract

A ventilation system for a helmet that incorporates various elements in different embodiments, including air flow channels in the safety padding, a shell on the safety padding underneath the external shell, thickening of the external shell in the areas of the air flow channels, extrusions in the external shell to facilitate air flow in the air flow channels, and vents in the external shell to feed and exhaust air flow.
