Abstract
Abstract A safety helmet exhibits, in the zone of the longitudinal line of symmetry of its chin protector, an upwardly projecting rubber-elastic material air duct member comprising a sealing lip. This sealing lip extends past the contact area of the visor on the chin protector to such an extent that the chin protector is in contact with the visor when the visor is opened a crack. Thus, the air stream entering the interior of the helmet is conducted toward the lateral regions of the window and cannot affect the eyes of the helmet wearer. Since the air duct member is made of a rubber-elastic material, the visor can be closed entirely. Additionally, the air duct member is provided with two lateral parts and a continuous water-conducting groove which is arranged in these parts and in the air duct member. Water can collect in the groove and be drained off in the rearward and downward directions.
