Abstract
A device to direct on the vizor the central part of the air flow entering from the helmet's front grating, while the other two air flows entering through lateral slots (12,12') are directed sidewise. The entry of the lateral air flows can be adjusted by means of hinged valves (30) made of flexible plastic material, the hinged ends of said valves being oriented toward the center line of the helmet, the valves being shifted by sliders (50) engaging with inclined plane (34) of the valves themselves.
Claims4
Device to ventilate helmets, in particular motorcyclists' helmets, the front of the helmet being provided in its lower part with a set of parallel slots communicating with the interior of the helmet characterized by a central box shaped body opened upwardly to deviate the air flow on the visor and provided by interception means to control air flow, and by two flapper valves fitted laterally with respect to said central body, each to deviate and to control an air flow sidewise of the helmet, said valves consisting of an elastic lamina made of flexible plastic material and being hinged on the lateral walls of said central box shaped body.
