Abstract

Ventilator roof for use in motor vehicles with a roof opening in a fixed roof surface which can be closed by a cover. The cover can be swung by pivoting around a pivoting axis, at, or near its rear edge, into a ventilation position in which the cover front edge is below the roof surface, while the cover rear edge is kept at the height of the roof surface, and a ventilation gap is formed between the cover front edge and the front edge of the roof opening. At least one electrically powered blower is built into a ventilation channel leading from the ventilation gap into the vehicle interior. The blower can be powered by solar cells or the on-board vehicle power unit (battery) with safeguards to prevent use when the vehicle power unit lacks sufficient charge. In some embodiments, arrangements are also provided to enable the blower to provide ventilation of the interior space of the vehicle even when the cover is closed.
