Abstract

The invention relates to a textile surface element (1) for arrangement on a vehicle, an outer side (A) facing a vehicle environment. According to the invention, the textile surface element (1) has a cell structure (Z) with opaque cell walls (4), a light-emitting light source (2) being arranged on an inside (I) of a respective cell (3) opposite the outside (A) and a light exit surface is arranged in the direction of the outside (A) and is formed by the latter.

Description

The invention relates to a textile surface element for arrangement on a vehicle, with an outside facing a vehicle environment.

From the EP 3 051 022 A1 a translucent synthetic leather and a method for its production are known. The synthetic leather has a textile backing material and a translucent layer structure, which is arranged on the textile backing material and connected to it. In addition, the layer structure comprises at least one layer based on polyurethane or polyvinyl chloride and a surface coating. The synthetic leather has a translucency for visible light in a range from 0.4% to 60%.

The object of the invention is to provide a textile surface element which is improved compared to the prior art.

The object is achieved by the features specified in claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims.

A textile surface element for arrangement on a vehicle has an outer side which faces a vehicle environment. According to the invention, the textile surface element comprises a cell structure with opaque cell walls, a light-emitting light source being arranged on an inside of a respective cell opposite the outside and a light exit surface being arranged in the direction of the outside and being formed by the latter.

In the case of a textile surface element designed in this way, color separation at border crossings, i. H. on the cell walls, between two different colors of light emitted.

A textile surface element designed in this way enables an essentially invisible light integration, wherein the textile surface element can be a textile outer skin of a vehicle.

In particular, visual effects can be projected from the inside to the outside of the textile surface element, so that, for example, it can be communicated visually.

Such a textile surface element can be produced comparatively easily and without great effort, the textile surface element representing a comparatively economical construction for visual communication, in particular of the vehicle, with the surroundings.

Exemplary embodiments of the invention are explained in more detail below with reference to a drawing.

• 1 schematisch eine perspektivische Ansicht eines Ausschnittes eines leuchtenden textilen Flächenelementes.

The shows:

• 1 schematically shows a perspective view of a section of a luminous textile surface element.

The single figure shows a perspective view of a section of a luminous textile surface element 1 . The textile surface element 1 is intended in particular for arrangement on a vehicle, with an outside A of the textile surface element 1 faces a vehicle environment. The textile surface element can 1 form a luminous, textile outer skin of the vehicle.

The textile surface element 1 is designed for the projection of visual light effects, with a light coming from outside A of the textile surface element 1 is emitted in a comparatively high quality of light, particularly with regard to color delimitation.

By means of the luminous textile surface element 1 is a visual communication with an environment by means of essentially invisible light sources 2nd feasible, with any color change of the textile surface element 1 is feasible.

To by means of the textile surface element 1 The textile surface element has the ability to reproduce relatively exact color contours 1 one a plurality of cells 3rd showing cell structure Z. on, with the cells 3rd by means of cell walls 4th are separated from each other. In particular, the cell walls 4th trained opaque.

According to the present exemplary embodiment, the cell structure is Z. formed as a honeycomb structure, the individual cells 3rd have a hexagon shape. As an alternative to the honeycomb structure, the cell structure Z. also have another useful shape.

On the inside I. of the textile surface element 1 is in every cell 3rd a light source 2nd , in particular in the form of an LED, arranged in the center. Each of the light sources 2nd emits light towards the outside A that a light exit surface of the textile surface element 1 forms.

In addition, the respective light source 2nd depending on a height of the cells 3rd depending on a distance between the inside I. and the outside A , at a given distance, e.g. B. between 1 mm and 50 mm, to the inside I. arranged and in particular held and fixed.

Because the cell walls 3rd are designed to be opaque, an undesirable mixing of colors of color-emitted light from the individual light sources 2nd largely excluded. Each wall thickness is less than 0.1 mm.

For example, the textile surface element 1 can also be used as a tarpaulin for a vehicle or for other suitable purposes, using a textile surface element designed in this way 1 any color change is possible.
