Abstract (en)
Shell (l0) of the helmet is provided with at least one, but preferably two ventilating air outlet holes (8) placed substantially on the vertical symmetry plane of the shell itself in a retracted position with respect to the summit of the shell, said hole/holes (8) being associated with an ejector device (4) apt to create a depression at the level of said outlet hole/holes to increase the discharge of the air, coming from the internal comfort padding (l8), through a radial duct (l6) provided in the thickness of the anti shock layer (l4), said duct leading to a chamber (l2) communicating in turn with said air outlet hole/holes. The ejector (4) comprises a slider valve (34) apt to open or close fully or partially said air outlet holes.
