an output device arranged on one or both of in the first end of the at least one rod element and on the cross-sectional surface of the first end of the at least one rod element.

3. The holding device according to claim 1 , further comprising:

a plurality of rod elements, wherein each of the rod elements is arranged to be adjustable along its respective main extension axis, and wherein the respective cross-sectional surfaces form a part of the holding surface; wherein the adjustment device is configured to adjust a part of the plurality of rod elements or each of the rod elements.

4. The holding device according to claim 1 , further comprising:

a damping device for damping a force acting on the at least one rod element.

5. The holding device according to claim 1 , further comprising:

a suction device for creating a vacuum on the holding surface.

6. The holding device according to claim 1 , further comprising one or both of:

a temperature-measuring device; and

a temperature-control element for one or both of heating and cooling of one or both of the at least one rod element and of the first end of the at least one rod element;

wherein one or both of the temperature-measuring device and the temperature-control element is arranged in or on the at least one rod element.

7. A method for operating a holding device of an interior trim element of the motor vehicle, wherein the following steps are executed by a control device:

determining a form of an object, which is situated in an interior of the motor vehicle;

determining a position on the holding device suitable for holding the object;

generating a holding surface form default signal, which describes an adjustment of at least one rod element of the holding device along its main extension direction, as a function of the determined form of the object and the determined position, such that the part of the holding surface, which is formed by a totality of cross-sectional surfaces, forms a holding element, which is at least partially fitted to the determined form, in the determined position; and

transferring the generated holding surface form default signal to the adjustment device of the holding device in order to adjust the at least one rod element, and thereby form the holding element.

8. The method according to claim 7 , further comprising:

Determining one or both of a biometric parameter of a user and a sitting position of the user of the motor vehicle; wherein the position on the holding device that is suitable for holding the object is determined as a function of the determined biometric parameter of the user.

9. The method according to any of claim 7 , further comprising:

determining a position or location change of a body of the user;

determining a current position of the holding element;

determining an alternative position of the holding element, in which the object stored in the holding element is more easily accessible to the user from one or both of the changed body position and body location, as a function of the determined position and/or location change;

generating a further holding surface form default signal, which describes an adjustment of a plurality of rod elements for moving the holding element from the current position into the determined alternative position; and

transferring the further holding surface form default signal to the adjustment device.

10. The method according to claim 7 for operating a holding device, further comprising:

defining a target value of a temperature of a content of the object; and

setting the defined target value by the temperature-control element of the holding device;

wherein the defining of the target value depends on one or both of a determined material of the object and a property of the determined object.

11. The method according to claim 7 , further comprising:

generating a lighting signal, which describes a lighting of the holding element by a display content to be displayed or by light, as a function of one or both of the determined suitable position on the holding device and a position of the holding element; and

transferring the generated lighting signal to an output device of the holding device for one or more of a) controlling the output device of the at least one rod element; and b) controlling a lighting element that impacts the at least one rod element with light.

12. A control device, having a processor device,

wherein the control device is configured to execute the process steps of:

determining a form of an object, which is situated in an interior of the motor vehicle;

determining a position on the holding device suitable for holding the object;

generating a holding surface form default signal, which describes an adjustment of at least one rod element of the holding device along its main extension direction, as a function of the determined form of the object and the determined position, such that the part of the holding surface, which is formed by a totality of cross-sectional surfaces, forms a holding element, which is at least partially fitted to the determined form, in the determined position; and

transferring the generated holding surface form default signal to the adjustment device of the holding device in order to adjust the at least one rod element, and thereby form the holding element.

13. The holding device according to claim 1 , wherein the holding device has a control device configured to execute process steps affecting the control device, wherein the following steps are executed by the control device:

determining a form of an object, which is situated in an interior of the motor vehicle;

determining a position on the holding device suitable for holding the object;

generating the holding surface form default signal, which describes an adjustment of at least one rod element of the holding device along its main extension direction, as a function of the determined form of the object and the determined position, such that the part of the holding surface, which is formed by a totality of cross-sectional surfaces, forms a holding element, which is at least partially fitted to the determined form, in the determined position; and

transferring the generated holding surface form default signal to the adjustment device of the holding device in order to adjust the at least one rod element, and thereby form the holding element.
