Functional Support with Button Functions

A process for producing a multifunctional functional support with a rigid support structure, in which at least one of operating elements and display elements are arranged behind a transparent surface layer which is continuous over substantially the entire multifunctional support, the process comprising:

• i) introducing a flat, flexible plastic film;
• ii) placing the plastic film in a positioned manner, into an injection mold, wherein the plastic film is supplied from a roll, and the plastic film is backmolded to form a substantially continuous rigid support structure on a first side, the injection mold being designed in such a way that, in a region of at least one of the operating elements and the display elements, the plastic film is not backmolded, at least in places, and remains exposed in the form of at least one clearance or at least two clearances;
• iii) flooding on a second side, facing away from the first side, of the plastic film in the injection mold or, after transferring the plastic film into a further injection mold, in this further injection mold, substantially all over with a transparent curing casting compound in an RIM process, and coating the second side to form a continuous transparent surface layer with a thickness of at least 0.1 mm over substantially the entire functional support, and membrane regions that are flexible at least in places are formed in a region of the clearances;
• iv) placing at least one of the operating elements and the display elements into the clearances and joining at least one of the operating elements and the display elements to the rigid support structure.
