Safety helmet, especially for users of automotive vehicles

摘要

The safety helmet has a viewing opening which can be covered by a visor. Several vent openings and air passage openings are arranged at the chin protector of the safety helmet. Such openings terminate together into an air-collecting chamber provided on the inside of the chin protector. Two ventilating tubes extending to the top edge of the viewing opening lead away from this air-collecting chamber. An air stream produced by a pressure head passes through the vent openings-as well as through the air passage openings if the visor is opened somewhat-into the air-collecting chamber and is conducted by the ventilating tubes onto the inside of the visor, thereby substantially preventing any fogging of the visor by moisture precipitation.
