A roof top for motor vehicles which is adapted to be detachably secured to the lower vehicle body and which includes a lower rear cross frame that forms a relatively wide gap with the top side of the rear part of the vehicle body; this gap which terminates at its rear end in the atmosphere, forms part of a line system of a ventilation installation for the passenger space; a ventilating channel is branched off from this line system whose air flow fans the outer surface of the rear window. |
