The vehicle interior trim part comprises a decorative layer, which has through-openings. In addition, the vehicle interior trim part comprises a reflective layer, which likewise has through-openings, the inner wall of the through-openings in the reflective layer being reflective. The through-openings in the reflective layer overlap at least in part with the through-openings in the decorative layer, such that a light path is formed at least in part. The reflective layer is at least 1.5 times as thick as the decorative layer in a periphery of the light path. ## Claims ### Claim 1 A vehicle interior trim part, comprising: a decorative layer, the decorative layer including one or more first through-openings; and a reflective layer, the reflective layer including one or more second through-openings; wherein an inner wall of the second through-openings are reflective, wherein the one or more first through-openings and the one or more second through-openings overlap at least in a region for forming a light path, and wherein the reflective layer is at least 1.5 times as thick as the decorative layer in a periphery of the light path. ### Claim 2 (depends on 1) The vehicle interior trim part according to claim 1, wherein a composite layer made up of the decorative layer and the reflective layer is at least the same thickness and at most 10 times as thick as a longest extension of a cross section of at least one of the one or more first through-openings or the one or more second through-openings perpendicular to the light path. ### Claim 3 (depends on 1) The vehicle interior trim part according to claim 1, wherein the reflective layer is at least twice as thick as the decorative layer in the periphery of the light path. ### Claim 4 (depends on 1) The vehicle interior trim part according to claim 1, wherein a reflectance of the reflective layer on the inner wall of the one or more second through-openings in the visible spectral range is at least 0.25. ### Claim 5 (depends on 1) The vehicle interior trim part according to claim 1, wherein the reflective layer is arranged behind the decorative layer. ### Claim 6 (depends on 1) The vehicle interior trim part according to claim 1, wherein the reflective layer is configured to reflect light from the inner wall before passing through the one or more first through-openings in the decorative layer. ### Claim 7 (depends on 1) The vehicle interior trim part according to claim 1, wherein the reflective layer has a higher reflection coefficient than the decorative layer. ### Claim 8 (depends on 1) The vehicle interior trim part according to claim 1, wherein the decorative layer is a leather layer. ### Claim 9 (depends on 1) The vehicle interior trim part according to claim 1, wherein the decorative layer and the reflective layer at least partially abut one another. ### Claim 10 (depends on 1) The vehicle interior trim part according to claim 1, wherein at least one of the one or more first through-openings in the decorative layer or the one or more second through-openings in the reflective layer are filled. ### Claim 11 (depends on 1) The vehicle interior trim part according to claim 1, wherein the decorative layer has a thickness of between 0.01 mm and 1 mm. ### Claim 12 (depends on 1) The vehicle interior trim part according to claim 1, wherein the reflective layer is a bleached white or grey leather. ### Claim 13 (depends on 1) The vehicle interior trim part according to claim 1, wherein an outer surface of the decorative layer is coloured. ### Claim 14 (depends on 1) The vehicle interior trim part according to claim 1, wherein the decorative layer is opaque. ### Claim 15 (depends on 1) The vehicle interior trim part according to claim 1, wherein a reflectance of the reflective layer on the inner wall of the second through-openings in the visible spectral range is at least 0.5. ### Claim 16 (depends on 1) The vehicle interior trim part according to claim 1, wherein at least one of the one or more first through-openings in the decorative layer or the one or more second through-openings in the reflective layer are unfilled. ### Claim 17 A vehicle interior trim part, comprising: a decorative layer, the decorative layer including one or more first through-openings; a reflective layer, the reflective layer including one or more second through-openings; and a composite layer made up of the decorative layer and the reflective layer; wherein an inner wall of the second through-openings are reflective, wherein the one or more first through-openings and the one or more second through-openings overlap at least in a region for forming a light path, and wherein the reflective layer is at least 1.5 times as thick as the decorative layer in a periphery of the light path, wherein the composite layer has a thickness at least as thick and at most ten times as thick as a longest extension of a cross section of at least one of the one or more first through-openings or the one or more second through-openings perpendicular to the light path. ### Claim 18 (depends on 17) The vehicle interior trim part according to claim 17, wherein the decorative layer has a thickness of between 0.1 mm and 0.7 mm. ### Claim 19 A vehicle interior trim part, comprising: a decorative layer, the decorative layer including one or more first through-openings; and a reflective layer, the reflective layer including one or more second through-openings; wherein an inner wall of the second through-openings are reflective, wherein the one or more first through-openings and the one or more second through-openings overlap at least in a region for forming a light path, wherein the reflective layer is at least 1.5 times as thick as the decorative layer in a periphery of the light path, wherein the reflective layer is arranged behind the decorative layer, wherein the reflective layer is configured to reflect light from the inner wall before passing through the one or more first through-openings in the decorative layer, wherein the reflective layer has a higher reflection coefficient than the decorative layer, and wherein the decorative layer has a thickness of between 0.01 mm and 1 mm. ### Claim 20 (depends on 19) The vehicle trim part according to claim 19, wherein the decorative layer and the reflective layer at least partially abut one another, wherein the decorative layer is a leather layer, and wherein a reflectance of the reflective layer on the inner wall of the one or more second through-openings in the visible spectral range is at least 0.5.
