1. An actuating apparatus of a motor vehicle, comprising:
an actuating element which is adjustable by loading with a magnetic field between a first position which provides a first vehicle function and a second position which provides a second vehicle function;
a magnetic device, wherein the actuating element can be loaded with the magnetic field by the magnetic device;
wherein the actuating element is an additively manufactured component and wherein the actuating element comprises a multiplicity of louver elements which are configured separately from one another and are interlinked with one another and are moveable relative to one another within a plane of extent; and
an air guiding device, wherein air is feedable from a surrounding area of the motor vehicle to the motor vehicle by the air guiding device, wherein a ventilation opening of the air guiding device is released by the actuating element in the first position and wherein feeding air into the motor vehicle is the first vehicle function, and wherein the ventilation opening of the air guiding device is closed by the actuating device in the second position and wherein preventing air feed into the motor vehicle is the second vehicle function;
wherein during an adjustment of the actuating element from the first position into the second position the actuating element is compressed in the plane of extent such that a base area of the actuating element is reduced, wherein during an adjustment of the actuating element from the second position into the first position the actuating element is stretched in the plane of extent such that the base area is increased, wherein the first position of the actuating element is parallel to the second position of the actuating element, wherein a curvature of the actuating element out of the plane of extent does not occur during the adjustment of the actuating element, wherein only a size of the base area changes during the adjustment between the first position and the second position, and wherein an orientation of the actuating element relative to the air guiding device is kept constant during the adjustment of the actuating element between the first position and the second position.
