Abstract: A dynamic air intake (A, A?) for vehicle, helmet or safety clothing and the like, including a rigid casing (1, 5; 1?, 5?) having an air inlet opening (A1, A1?), an air outlet opening (A2, A2?) and a closed channel (1.4, 1.5, 3, 5; 1?, 1.4?, 25, 3?, 5?) for the passage of an air flow passing between said inlet opening (A1, A1?) and said outlet opening (A2, A2?), comprising air/water filter separation means including at least one layer (3, 3?) of material which absorbs rainwater and/or nebulised water, water vapour, arranged along said channel (1.4. 1.5, 3, 5; 1?, 1.4?, 25, 3?, 5?), without obstructing the cross section of the same channel, in direct contact with said passing air flow and in which water and water vapour, which are transported by said passing air flow, are gradually collected and released to be dispersed towards the outside of said rigid casing.

Abstract: A safety helmet (10), including a rigid outer shell (11) and an inner part (11.1) made to absorb and deaden any impact endured by said helmet, and comprising an inner padding (14c) which provides a canalisation structure (16) for conducting air between said at least one air intake opening (12.1) and said at least one air extraction opening (13.1), characterized in that it comprises a cap (15), which, when the helmet is worn by said person, cooperates with said padding to provide a plurality of air channels at said canalizations of said padding and covers the head of the person at least at the padding itself.
