The trim part includes a layered structure having at least a base support, a functional layer and a haptic layer. The functional interior trim part includes an electrical shielding layer. The electrical shielding layer leads to a selective sensor field expression in the direction of an operating half-space. The electrical shielding layer is arranged on a side of the functional layer facing away from the haptic layer. A method for manufacturing the interior trim part is also disclosed. ## Claims ### Claim 1 A functional interior trim component for a vehicle, comprising: a layered structure comprising at least a base support, a functional layer and a haptic layer; an electrical shielding layer comprising leads to a selective sensor-field expression arranged in a direction of an operating half-space, and wherein the electrical shielding layer is arranged on a side of the functional layer facing away from the haptic layer. ### Claim 2 (depends on 1) The functional interior trim component for a vehicle according to claim 1, wherein the electrical shielding layer is a grounded or groundable grounding layer. ### Claim 3 (depends on 1) The functional interior trim component for a vehicle according to claim 1, wherein the electrical shielding layer comprises a conductive material arranged at least in regions. ### Claim 4 (depends on 1) The functional interior trim component for a vehicle according to claim 1, wherein the electrical shielding layer comprises a coating of a conductive material. ### Claim 5 (depends on 1) The functional interior trim component for a vehicle according to claim 1, wherein the functional layer comprises a plurality of conductive tracks. ### Claim 6 (depends on 1) The functional interior trim component for a vehicle according to claim 1, wherein the haptic layer comprises a soft material arranged at least in regions. ### Claim 7 (depends on 1) The functional interior trim component for a vehicle according to claim 1, wherein the functional layer is arranged functionally connected or connectable to a controller. ### Claim 8 (depends on 1) The functional interior trim component for a vehicle according to claim 1, wherein at least the base support, the electrical insulation layer, the functional layer and the haptic layer are formed at least in regions from a transparent or translucent material such that light can be transmitted from the base support to the haptic layer. ### Claim 9 A method of manufacturing a functional interior trim component for a vehicle, the method comprising the steps of: providing a base support; providing a functional layer and a haptic layer, providing an electrical shielding layer on the base support, the electrical shielding layer comprising leads to a selective sensor-field expression in a direction of an operating half-space, and laminating the electrical shielding layer together with the functional layer to form a composite and then subsequently bonding the composite to the base support or to the base support in advance. ### Claim 10 (depends on 9) The method according to claim 9, wherein the bonding of the composite of electrical shielding layer and functional layer to the base support is integrated by back-injection molding of the base support.
