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: An adjustment drive that includes an electric motor, a transmission having a self-locking transmission stage, an output, and a safety clutch having a free travel. The safety clutch is operable to separate, in an event of an excessive external torque introduced via the output, the self-locking transmission stage from the external torque. The adjustment drive also includes at least one compressible damping element arranged in the free travel to enable haptics of an external movement demand introduced via the output.

Abstract: A rotor for an electric motor includes a hub, formed of a plastic material, having a bore and a resilient hub finger; a magnetic ring rotationally connected to the hub; and a fixed axle arranged in the bore for receipt of a radial force applied by the resilient hub finger to facilitate rotation of the hub about the fixed axle.

Abstract: A folding device to move a mirror head relative to a mirror base of a motor vehicle exterior mirror, the folding device including a carrier operatively connected to one of the mirror head or the mirror base, a motor arranged in the carrier, and which has a motor shaft, an output device operatively connected to one of the mirror base or the mirror head, and a gear mechanism to operatively connect the output device to the motor shaft. The motor shaft and the output device are located parallel with each other, and the motor, the output device, and the gear mechanism are positioned relative to each other via the carrier, such that the axial spacings of the motor shaft, the output device, and the gear mechanism located therebetween are determined via the carrier.

Abstract: A folding device to move a mirror head relative to a mirror foot of a motor vehicle exterior mirror. The folding device includes a carrier operatively connected to one of the mirror head or the mirror foot, a motor attached to the carrier, the motor having a motor shaft, an output drive operatively connected to one of the mirror head or the mirror foot, a gear mechanism to operatively connect the output drive to the motor shaft, and a pressure device operatively connected to the carrier to engage and press the motor shaft against the motor.
