Abstract
An improved motor vehicle roof is provided which includes a roof opening provided in a fixed roof surface, at least one closing element for selectively at least partially closing the roof opening, an electrical adjusting drive for driving the closing element and a sensor engineering system for detecting a situation which adversely affects the safety of the passengers and for producing a corresponding danger signal. Importantly, the roof includes a quick-action closing device coupled to the sensor engineering system which causes the closing element to close from its open or partially open position when a danger signal is present. The closing device includes means for producing an electrical voltage which exceeds the normal feed voltage (rated voltage) of the adjusting drive by several times, and for applying the voltage to the electric adjusting drive.
