A method for producing a three-dimensional motor vehicle interior element through which light can shine and which has an observer-side surface is produced in two steps. In a first step a three-dimensional transparent substrate is produced from a cross-linked polymer. In a second step the substrate is provided on an observer-side surface of the substrate with a coloring through which light can shine, at least in a subregion.

Method for producing a three-dimensional motor vehicle interior element through which light can shine, and a motor vehicle interior element

A method for producing a capacitive contact sensor and a capacitive contact sensor having a carrier plate made of plastic are described. The front surface of the sensor initiates a switching process when contacted, and the rear surface of the sensor has one or more capacitive sensor electrodes disposed thereon and connected via conductors to analysis electronics. The regions on the front surface of the carrier plate opposite the sensor electrodes thereby form contact zones. A plastic film supporting the sensor electrodes and conductors is placed on a first side wall of a cavity of an injection molding tool, wherein the sensor electrodes face the first side wall, and then a polycarbonate forming the carrier plate is injected into the cavity on the side of the plastic film facing away from the sensor electrodes. The cavity is then expanded, forming a gap on the side facing away from the plastic film and the gap is injected with a further plastic reacting with the polycarbonate in the contact region and forming a scratchproof coating.
