Description

TECHNICAL AREA

The invention relates to a Interieurteil and a method for producing a Interieurteils having an opening to be bridged in one or more decorative elements of the Interieurteils.

BACKGROUND OF THE INVENTION

It is known to make the illumination of vehicle interiors with the aid of optical fibers. The light guide here serves both to generate directly visible lines of light, as well as to produce an indirect illumination, which is also referred to as ambient lighting.

In addition, interior parts of vehicle interiors have openings, which come about, for example, that two decorative elements are joined together. In this case, the opening is a gap. A functional bridging of such an opening takes place only slightly in the prior art. However, it is known in this regard to sew optical fibers by means of a fastening lug in column of the type described above. The US 2010/0296302 A1 describes an interior component in which a strip of a light-conducting polymer material is sewn into a gap between two cladding elements. Alternatively, openings or gaps may be artistically emphasized by decorative stitching, as is common practice in high-end interior trim of upper and upper class vehicles.

BRIEF DESCRIPTION OF THE INVENTION

An object of the invention is to provide an interior design with one or more decorative elements and a method for producing such an interior judgment, in which an opening in the decorative element is bridged in a functional and optically innovative manner.

The object is achieved with a Interieurteil according to claim 1 and a method according to claim 13. Advantageous embodiments are defined in the dependent claims and also result from the following general description of the invention and the description of embodiments.

The interior of the invention has one or more decorative elements and an opening in the one or between the plurality of decorative elements. In the opening, a filler material is introduced, which has a light guide. In addition, the cross section of the filling material is deformable, preferably, the cross section of the filling material is compressible and expandable. Due to the deformability of the cross-section, the filling material can adapt to different opening geometries. For example, the filling material can compensate in this way a variable gap width between two decorative elements in a simple manner. In addition, the sewing process for forming the seam according to the invention, which at least partially spans the opening and at least partially over the filling material, can be positively influenced by the pressure from the inside, which results from the flexible, compressible nature of the filling material. This results in a technical synergistic effect between the desire to provide a decorative seam for overstretching the opening and a filling material for optically filling the opening.

In particular, in leather trim in vehicles or equipment with leather-like materials game takes place between adjacent decorative elements, so that a very precise and durable gap is not or only very difficult to accomplish. A change in distance can be done for example by the internal material, which can expand and contract under temperature and pressure or other external influences. The elasticity of the filling material allows for optimal adaptation to the gap and a tensioned support by the seam. With the help of the bridging of the present invention, a game in the decorative element or between decorative elements can thus be compensated. The bridging widens and puts the seam under tension. The seam can certainly press into the bridging material.

Preferably, the opening is an elongated gap and preferably the filling material is elongate, wherein the cross section of the filling material is deformable perpendicular to the extension, preferably compressible and expandable. The advantages of the invention described above apply to a great extent to the case of elongate openings, in particular in the case of a gap between two or more decorative elements.

The nature of the light guide can be as follows: standard light guide, light guide one or more parts, light guide of a conductor layer with printed light sources (eg LED) or partial coatings (eg reflector layer), which are necessary for a light generation, with / has no transparent lichtdurchstahlenden areas.

Preferably, the light guide is in cross section in the longitudinal direction to its extent Compressible and / or expandable, where appropriate, can be dispensed with an additional flexible material for the production of the filling material.

For the filling material are in particular and preferably deformable thermosets, elastomers, thermoplastics, crosslinked thermoplastics, compact or foam materials, PE, PP, PVC, PUR, glass, metal, PMMA, PC, COC, PES, composite materials, fiber composites or a combination in question ,

The filler material preferably has a bridging material which at least partially surrounds the optical waveguide with or without additional light source equipment. Such a bridging material serves for stabilization, for influencing the light and for protecting the light guide. In addition, the bridging material can facilitate the attachment of the light guide in the opening, for example by sewing or gluing. In particular, it is preferred that the bridging material at least partially surrounds the optical waveguide on the visible side of the interiors, whereby the optical waveguide is fixed and protected from external influences. In this case, the bridging material is on the front side, i. H. the visible side of the Interieurteils at least partially transparent to ensure a visual appreciation of the opening by means of the light guide. The light guide can be in one piece or in several parts.

Preferably, the bridging material is made of film, metal, leather, artificial leather, a leather-like material, wood, paper and / or textile. In particular, the above-mentioned materials come into question, d. H. deformable thermosets, elastomers, thermoplastics, crosslinked thermoplastics, PE, PP, PVC, PUR, glass, metal, PMMA, PC, COC, PES, ABS or a combination thereof.

Preferably, one or more of the decorative elements at the edge of the opening on a Umbugbereich. The Umbugbereich a visually appealing, stable and resistant conclusion to the opening is achieved. The fold preferably produces a comparatively sharp-edged transition between the filling material and the at least one decorative element. With a sharp-edged Umbug a minimal gap can be achieved with relatively well-defined dimensions.

Preferably, the filler material is not lowered, d. H. it is flush with the plane of the decorative elements or introduced into the opening in the visible, so that the above-mentioned optionally under tension connection of decorative element, filling material and seam can be accomplished particularly well.

Preferably, one or more of the decorative elements has a decorative layer of leather, synthetic leather or a leather-like material, since the present invention is particularly suitable for these materials.

Preferably, one or more decorative elements in the region of the opening and / or the filling material has one or more bores which are used in the assembly of the decorative materials with the filler material for vacuum suction. This aspect will be described in more detail below.

Preferably, a dimensionally stable carrier is provided on the side facing away from the visible side of the Interieurteils, whereby the Interieurteil is stabilized and prepared for further processing and mounting in the interior of a vehicle.

Preferably, an adhesion promoter is provided between one or more of the decorative elements and the filling material in order to strengthen the composite of decorative element and filling material.

The production of the inventive Interieurteils first requires an arranging and positioning of the or the opening having decorative elements in a first tool. This tool preferably has a time-controllable vacuum suction possibility in order to ensure a gentle and precise fastening of the decorative elements during further processing in the first tool. In a further step, the filling material is introduced into the opening, preferably using a vacuum device and preferably using a tempering device. Alternatively, a combination of vacuum and overpressure, an HPF process, or other process based on pressure differences may be used. Preferably, a heat activatable adhesive, such as in a mask application, introduced between the decorative element and filler material, wherein the adhesive is preferably reduced or suitable for heat activation. The adhesive may have light-influencing properties in interactions with the bridging material and / or decorative material and the light guide (light transmission behavior, light reflection behavior, light absorption behavior). In a further optional step, a functional haptic layer can be applied to the decorative element / filler composite, wherein here too a heat-activatable adhesive, for example in a mask application, is provided between the decorative element / filler composite and the haptic layer. Again, the adhesive may be reduced or provided completely heat-activated. In a next step, the composite is optionally pre-positioned on a dimensionally stable support, for example in a second tool, wherein preferably a heat-activatable adhesive between composite and dimensionally stable support is introduced. Thereafter, the composite is removed and placed in a laminating press, in which the final composite is produced under pressure and temperature. In this way, a low-gap "marrying" of the decor or the elements and the filling material can be completed. In addition, in this way functional and thin-layered interior parts with different decor arrangement can be produced in a simple manner.

The functionalization described above lies in the combination of the filling material with the seam. It can serve as a light and / or tactile guide, in which respect further structural elements can be introduced, for example for accentuation to the surrounding decorative material. In addition, a closing of the opening takes place in an elegant manner, as well as a joining of decorative elements, optionally with a gap-reduced transition. Optionally, wrinkles can be introduced with the filling material into the opening or the gap. The filling material may have a memory effect with regard to its shape as a further aspect.

Although the present invention has been described in terms of a car interior design, it is to be understood that the invention may be practiced in other fields such as aerospace and marine, furniture, home automation, etc. Further, there are others Advantages and features of the present invention will become apparent from the following description of preferred embodiments.
