Definitions
- the present invention relates to a method for producing a decorative composite which has a cushion-like surface structure on its visible or decorative surface.
- the invention also relates to a decorative composite for a motor vehicle.
- the decorative composite with the cushion-like surface structure or cushion structure is intended in particular for use in the automotive sector, for example as a decoration or part of a decoration in an interior of a motor vehicle, in particular a passenger car and/or truck.
- Possible applications of such a decorative composite are, for example - in particular illuminated/illuminable or backlit/backlit - symbols (warning symbols, status indicators, etc.), emblems (coats of arms, manufacturer symbols, logos, vehicle model and/or series names, etc.), functional decors ( Interior or ambient lighting, button and/or switch surfaces, etc.), seams, seam imitations (e.g. decorative seams, functional seams, cross seams, etc.).
- the decorative composite can serve as a cladding element for a loudspeaker.
- a decorative cut of the decorative composite or the entire decorative composite has, for example, one or more through openings that can be transilluminated or backlit and/or are permeable to ventilation or sound (“sound permeable”).
- Individual cushions of the cushion-like surface structure are usually separated from one another by connecting seams, which are created in particular by sewing or stitching, so that the individual cushions rise between the connecting seams from a plane of the connecting seams. So that the cushion structure can be formed particularly uniformly, a flexible decorative blank is used for a conventional decorative composite.
- a method for producing a decorative composite is proposed.
- a decorative composite is proposed which was produced using the method.
- the method according to the invention is therefore used to produce the decorative composite.
- the decorative composite according to the invention is a product that was/is produced using the method according to the invention.
- the method for producing the decorative composite has the steps explained in more detail below, which can take place in a different order than the description. Furthermore, the steps can at least partially overlap each other in time or at least partially begin, run and/or end at the same time. In other words: First, the individual steps involved in the process are explained; their order arises in connection with the description, in particular through the description of the possible ones Designs of the procedure. If necessary, the order of the steps differs from possible embodiment to possible embodiment.
- the decorative composite has a decorative side or decorative side which faces into the interior when the decorative composite is installed in the intended position, that is, when the decorative composite has been installed as intended in a vehicle, in particular a motor vehicle.
- the decorative composite has a back that faces away from the interior when installed in the intended position.
- the decorative composite can, for example, be attached to a dimensionally stable support, for example laminated onto the support.
- the term “formally stable” means that the shape of the wearer is self-supporting or inherently stable; This means that as long as a sufficiently strong deformation force does not act on the carrier, the decorative carrier will not be deformed.
- the decorative carrier can, for example, have wood, glass, metal or another rigid or dimensionally stable material as the material.
- the carrier can have or be formed from plastic, for example ABS (acrylonitrile butadiene styrene), PMMA (polymethyl methacrylate), PP (polypropylene), PC (polycarbonate), PU (polyurethane), ABS-PC (blend), etc
- plastic for example ABS (acrylonitrile butadiene styrene), PMMA (polymethyl methacrylate), PP (polypropylene), PC (polycarbonate), PU (polyurethane), ABS-PC (blend), etc
- the plastic is used as a matrix for reinforcing fibers, such as natural, metal or carbon fibers, so materials such as PP-GF, PU-GF, NF-PP etc. are also conceivable for the carrier.
- the carrier can be translucent, transparent or opaque.
- the decorative composite has a decorative blank which has a decorative side which forms the decorative side of the decorative composite in the finished decorative composite.
- the decorative blank also has a coating side which is spaced from the decorative side by a thickness of the decorative blank.
- the coating side can be processed using a smoothing process.
- the decorative cut extends predominantly two-dimensionally between the decorative side and the coating side.
- the respective decorative cut is therefore in particular a plan product made of a textile, a textile-like material, leather and/or artificial leather.
- film structures made of these or other materials are conceivable, such as TPO (thermoplastic polyolefins) etc.
- Natural, renewable and/or synthetic leather substitutes are also used as materials for the respective decorative cut hot-stamped textiles come into question.
- Other options include Alcantara ® or Dinamica ®.
- a material structure made of a mixed material is conceivable, which has, for example, one or more of the aforementioned materials.
- the decorative cut can be multi-layered, for example made of a leather or artificial leather layer and a textile or Fleece layer, be formed. If two or more decorative cuts are used, they can be made of the same or different material.
- the respective material can be transparent or non-transparent and/or permeable or non-permeable to acoustic waves.
- the decorative blank can be completely or partially pre-coated with a polymer on its coating side, the polymer being in particular transparent.
- the pre-coating is used, for example, to bind fibers and can contain additives (waxes, oils, color pigments, etc.).
- the pre-coating gives the decorative cut improved trimability.
- cavities in the decorative blank can be filled.
- An example of an application is partially embedding the textile backing of an artificial leather.
- the coating side of the decorative blank is coated with a coating material in a coating area, the coating area being characterized or predetermined by the predetermined connection contour.
- the coating side of the decorative blank is only coated with the coating material in exactly the area that is specified by the predetermined connection contour.
- the coating area is specified or characterized by the connection contour in that the coating area lies outside the connection contour.
- the connecting contour reproduces a pattern on the finished decorative composite, according to which, for example, individual cushions of a cushion structure of the decorative composite are separated from one another and arranged relative to one another. This pattern can be regular or irregular.
- the coating material can in particular only be formed in a predetermined portion of the coating area, for example in a symbol area, of the cushion structure or a (respective) individual cushion of the cushion structure.
- a symbol arranged or formed in the symbol area can (but does not have to) be formed by means of a perforation or have such a perforation.
- the coating follows, for example, the contour of the perforation or openings (for example line-like gaps). In addition to the contour of the openings, the coating can be seamless.
- the decorative blank is then placed with the coating side partially coated with the coating material on a lining element which is reversibly elastically compressible along its thickness direction.
- a layer arrangement is formed which has the decorative blank and the lining element.
- the underlining element has at least one reversibly elastically compressible layer.
- the underlining element can be constructed in multiple layers, with the individual layers being connected to one another, for example, by means of a light-transparent and/or UV-stable adhesive. It can also, in particular, have a carrier layer which is connected to the reversibly elastically compressible layer.
- the underlining element can have a cover layer, so that the reversibly elastically compressible layer is arranged between the carrier layer and the cover layer.
- the reversibly elastically compressible layer of the underlining element is, for example, a textile structure, foam structure, sponge structure, cotton structure, etc.
- Textile structures here include, among other things, a woven fabric, a knitted fabric, in particular a spacer knitted fabric, a knitted fabric, a braid, to understand a sewn fabric, a fleece etc.
- Threads or fibers of the lining element are in particular plastic fibers.
- Layers of the layer arrangement i.e. at least the decorative blank and the lining element, can lie loosely on top of one another or can be fixed relative to one another in a non-positive, positive and/or material fit.
- the connecting contour is compressed, for example by means of a pressing element.
- the compression can alternatively or additionally be carried out using a connecting means used to connect the decorative blank and the lining element, such as a thread, a rivet, etc.
