<p>There is disclosed a visor (16) for a safety helmet (10) comprising at least one aeration window (18) and outer opening/closing means (20) of at least one aeration window (18) fixed slidably on the visor (16) in order to allow adjustment of the flow rate of outside air entering the safety helmet (10) through the at least one aeration window (18). The visor (16) further comprises inner deflector means (22) also fixed slidably on the visor (16) opposite with respect to the outer opening/closing means (20), so as to be movable between a lower position, in which they free the at least one aeration window (18), and an upper position, in which they intercept it, directing the flow of air entering the helmet upward, so as to lick in a substantially distributed way the face of a user wearing the safety helmet.</p> |
