ABSTRACT:
A fresh-air supply system for a vehicle ventilation device through an air inlet opening in a bonnet or hood swivellably attached to the vehicle bodywork, has a fresh-air duct which starts from the air inlet opening, the first duct portion of which is arranged underneath the air inlet opening on the bonnet and the second duct portion of which is arranged immovably on the bodywork. The two duct portions of the fresh-air duct are brought by the closing movement of the bonnet into a connection position in which a circumferential sealing flange of the first duct portion cooperates with a corresponding sealing flange of the second duct portion. The cooperating sealing flanges of the two duct portions, lying in an approximately horizontal plane, are covered over by the bonnet. The first duct portion is a water-collecting box surrounding the air inlet opening and having a drainage device. An overflow opening from the first duct portion to the second duct portion lies above the drainage level in the first duct portion, in a manner protected from direct ingress of water.
