Abstract: Adjustment drive includes an electric motor, a transmission, at least one engaging element, and a resilient element. The transmission has a self-locking transmission stage, a power takeoff, and a safety coupling that separates the self-locking transmission stage from an external torque in response to an excessive external torque introduced via the power takeoff. The safety coupling has a motor-side gearwheel with at least one coupling contour and at least one engaging contour, a power takeoff-side gearwheel, a free-running mechanism formed by the at least one coupling contour, and coupling elements operable to establish a positive-locking connection between the motor-side gearwheel and the power takeoff-side gearwheel. The at least one engaging element is rotationally secured to the motor-side gearwheel or the power takeoff-side gearwheel.

Abstract: A drive arrangement for adjusting an aerodynamic flap on a vehicle. The drive arrangement includes an electric motor, a spur gear mechanism having gear stages, an output shaft, and at least two housing halves. The spur gear mechanism includes at least one self-locking gear stage that does not form the first gear stage nor the last gear stage of the spur gear mechanism. A safety coupling is arranged between the self-locking gear stage and the output shaft to disengage the output drive on overload in order to protect the flap attached thereto from damage.

Abstract: A system of exterior mirrors having a mirror head and a mirror foot, the system including a first mirror which is configured to rotate about and also move vertically along a first axis defined by a first drive for the first mirror, and a second mirror which is configured to rotate about a second axis defined by a second drive for the second mirror.
