Description

The invention relates to a flexible sheet-like structure for the interior of a vehicle, in particular for a vehicle seat, according to the preamble of claim 1. The invention also relates to a seat cover according to claim 8, a vehicle seat according to claim 9 and a vehicle according to claim 10 flexible sheet-like structure has an essentially opaque cover layer, a luminous means and at least one essentially transparent spacer layer which is at least partially arranged between the luminous means and the cover layer.

State of the art

Such a flexible sheet-like structure is from DE 10 2015 102 407 A1 known. This known flexible flat structure is a flexible flat light which is intended in particular for use in an item of clothing. In this surface light, the lighting means are arranged at a distance from a reflective layer by a spacer layer and their light exit side faces this reflective layer. Light emitted by the lighting means is reflected on the reflective layer and scattered on its further path to the cover layer in the spacer layer and further spacer layers. This is intended to achieve uniform light emission from the top layer. The spacer layer is arranged over the illuminants after positioning the illuminants and is elastically deformed when the illuminants press into the spacer layer.

A surface light for a vehicle is also from the DE 10 2013 021 690 A1 known. This surface light has layers of plastic material and is therefore not a flexible, but an essentially rigid surface structure. In particular, the surface light is therefore not suitable as a cover fabric.

From the WO 2018/082810 A1 a flexible sheet-like structure for the interior of a vehicle, a seat cover with the flexible sheet-like structure, a vehicle seat with the seat cover and a vehicle are known. In particular, the flexible sheet-like structure is provided for a vehicle seat and has an at least partially light-permeable cover layer, lighting means and an at least partially light-permeable spacer layer which is at least partially arranged between the lighting means and the cover layer. According to the invention, the spacer layer has at least one embossed line in which the lighting means are received. This provides a large-area background lighting for a flexible planar structure in the interior of a vehicle.

task

The invention is based on the object of improving a flexible planar structure of the type mentioned at the beginning, in particular to provide a planar structure with precisely defined luminous areas. Furthermore, a seat cover for a vehicle seat, a vehicle seat and a vehicle are to be provided.

solution

The object is achieved according to the invention by a flexible sheet-like structure for an interior of a vehicle, in particular for a vehicle seat, with an essentially opaque cover layer, with a light source and with at least one essentially light-permeable spacer layer, which is at least partially arranged between the light source and the cover layer is, wherein the cover layer has recesses through which a light emitted by the illuminant passes.

Because the cover layer has recesses through which a light emitted by the luminous means passes, regions of the flat structure can be precisely defined which appear to be luminous when the luminous means is activated.

“Essentially translucent” in the context of this invention is understood generally and in particular with regard to the cover layer to mean that incident light can pass through in a proportion of up to [xxx approx. 50 to 99% xxx].

“Essentially opaque” in the context of this invention is understood in general and in particular with regard to the cover layer to mean that incident light with a proportion of less than [xxx approx. 5% xxx] passes through.

At least one further spacer layer, in particular precisely one further spacer layer, is preferably arranged between the spacer layer and the cover layer. The respective spacer layer can be a textile layer. The respective spacer layer can be made of a foamed material. The foamed material is preferably colourfast and made of a non-yellowing foam material. The respective spacer layer preferably has scattering elements on which light passing through the spacer layer is scattered. The respective spacer layer is particularly preferably a 3D spacer fabric or a 3D spacer knitted fabric or a 3D spacer knitted fabric. Threads of the respective textile layer are therefore scattering elements in the Spacer layer where light is scattered or also diffracted. The spacer layer can preferably be transparent. The spacer layer is preferably designed in such a way that a color composition of the light is unaffected. The spacer layer can also be designed in such a way that a color composition of the light radiating through the spacer layer can be influenced in accordance with a predetermined property. Overall, this ensures a uniform distribution of light in the area of the cover layer and thus a uniform, two-dimensional appearance of luminous areas of the flexible flat structure.

The flexible sheet-like structure preferably also has a carrier layer, the spacer layer and the lighting means being arranged between the cover layer and the carrier layer. Light in the spacer layer is thus wholly or partially prevented from exiting the flexible sheet-like structure on the rear side of the flexible sheet-like structure which faces away from the cover layer. At least some of the light in the spacer layer is reflected on the carrier layer. The carrier layer is in particular a textile layer, particularly preferably a fabric layer.

The cover layer can be a textile layer. The recesses in the cover layer can be cut free by means of a laser. The cover layer can be printed at least on its exposed upper side by means of an ink printer or by means of screen printing and / or be manufactured as a combination of several textiles. The lighting means can be light-emitting diodes. A colored composition of the light emitted by the illuminants can be adjustable. The lamps can emit colored light. The layers can be glued to one another at surface sections lying on one another.

A seat cover according to the invention for a vehicle seat has a flexible sheet-like structure according to the invention. A vehicle seat according to the invention has a seat cover according to the invention. A vehicle according to the invention has an interior trim with a flexible sheet-like structure according to the invention in the interior of the vehicle and / or has a vehicle seat according to the invention.
