Abstract
A crash helmet (1) for sports, such as cycling, in which, to optimize ventilation for the wearer and so minimize the effects of sweating, the crash helmet consists of a supporting cap (2), designed to be worn on the top of a person's head, and an outer cap (3) designed to fit on top of the supporting cap (2) and permanently connected to the latter; the supporting cap (2) has a plurality of first through holes (5-9) in channels which are opposite the inner surface of the outer cap (3); the front of the outer cap (3) has at least second through holes (18, 19, 20) which communicate with a channel in the supporting cap, and with a first hole (5-9) in the supporting cap; the rear zones of the caps (2,3) together form, at the channels in the supporting cap, an equal number of matching passages (27, 28, 29) which communicate with corresponding second hole (18, 19, 20) and are open at a rear zone of the crash helmet (1); thus between the supporting cap (2) and the outer cap (3), there is a system of channels with Venturi effect, communicating with the head of the crash helmet wearer.
