Abstract

A drive device with override function for a moving device in motor vehicles includes a drive element, an output element with a rotationally symmetrical surface connected to the moving device, and a connecting device, which under a drive-side load transmits a drive torque to the output element and in the absence of the drive-side load releases the output element. The drive device further includes a carrier wrap spring, which is operatively connected to the drive element and can be brought into engagement with the rotationally symmetrical surface of the output element, together with a control element, which under a drive-side load braces the carrier wrap spring with the rotationally symmetrical surface of the output element and in the absence of the drive-side load releases the bracing of the carrier element with the rotationally symmetrical surface of the output element.
