Abstract
A process and arrangement for the ventilation of the interior of a motor vehicle is provided, whereby the motor vehicle has a ventilating device and a roof having at least one roof opening which can be opened and closed by displacement of at least one cover by means of an actuating device, like in a sliding roof, a sliding-lifting roof, a lifting roof, a spoiler roof, a folding roof, or the like, and whereby the ventilation device and actuating device for the roof cover are operatively connected in such a way that, when the roof is at least partially opened, the ventilation device of the vehicle is automatically activated to increase ventilation of the vehicle interior, which activation can be effected in corresponding ventilation stages. Alternatively, to avoid air congestion in the vehicle interior, when the ventilation device is activated, the roof opening can be automatically opened by the actuating device, whereby, for example, in the case of a sliding-lifting roof, the cover of the sliding-lifting roof is brought into its extended position. In similar manner, in other vehicle roof designs, the respective adjustable roof parts are brought to an appropriate position by either an automatic control element or a manual control.
