Abstract: A motor vehicle roof with a roof opening in the fixed roof skin and with two successive adjustable covers for closing and partially clearing the roof opening. At least one of the covers is displaceable in the lengthwise direction of the motor vehicle into an open position and is swingable out of its closed position into a ventilator position by selectively lowering a front around the respective rear edge. The rear cover may be pushed out of its tilted ventilator position to under the closed front cover into an open position by being moved forward in its tilted position over most of its path of motion and then being lowered at its rear edge on the last section of the path of motion to essentially move completely under the front cover. Alternatively, the front cover can be moved rearward in its ventilator position to a point substantially overlying the rear cover in its ventilator position.

Abstract: A test routine for a throttle-valve displacement device is accomplished by use of a potentiometer (6) associated with a setting drive (3) and a potentiometer (5) associated with the throttle valve (1) to determine if the valve is operating properly. If it is found from a comparison of the potentiometer signals that the throttle valve (1) is connected to the gas pedal (2), then the setting drive is moved at specific time intervals at least once in closing direction and then back into the starting, position, and it is tested whether the throttle valve (1) follows the setting device. If so, then there is an erroneous indication of one of the two potentiometers and safety measures can be taken.

The desired-value transmitter has an electric path converter which gives off an electrical desired-value signal. In order to verify the proper operation of the return spring, a contact spring (9) of a first safety switch contact (10) acts on it in such a manner that the force of the return spring is transmitted to the contact spring. In the event that the return spring is broken, the safety switch contact assumes a position which is characteristic of this and gives off a corresponding signal which can reduce the output of the engine. The electric path converter may be a potentiometer.
