Description

The present invention relates to a method for producing a deformable trim part, in particular for a vehicle. The invention further relates to such a trim part.

A trim part is usually used for decorating an object or a component. As a result, the appearance of the component are changed and / or increased the value of the component. Usually, the component is provided with a decorative material for decorating. Such decorative materials include in particular wood, aluminum and plastic. Due to their rigidity, these decorative materials have limits on deformability, so that they can not be attached to an arbitrarily shaped component. In this case, such components often and increasingly on decorating forms, the complex geometries, in particular waves, plates, bends and the like, have. If one tries to adapt such a decorative part, in particular the associated decorative material, such a shape of the component, it often causes damage to the decorative material, such as cracks and / or folds of the decorative material. These damages can make the trim unusable or they require a costly reworking of the molded into the desired shape trim. For example, if wood is used as a decorative material, then these post-processing may include, for example, the cementing and / or pickling and / or coloring of the decorative material. Overall, the manufacturing costs and production costs are thereby significantly increased. In addition, for this reason, only a limited, suitable for such deformations, number of materials, in particular types of wood, can be used.

To improve the deformability of such a trim part, it is from the DE 101 24 913 C1 and the DE 20 2005 011 383 U1 known to bring in a trim with a decorative material made of wood, in the wood grooves that have a smaller depth than a wall thickness of the wood. Subsequently, the wood is cut along the grooves in such a way that this results in separate wood sections. Subsequently, a reversibly deformable cross-connection is introduced into the gaps or spaces between the wood sections and the wood sections are glued together. To deform the resulting decorative part of the cross-bond is brought by heat treatment in its deformable state and then shaped the trim part in the desired shape.

Such a realization of the trim part and / or such an adaptation of the trim part to a desired shape, however, require a high manufacturing outlay and / or a complicated deformation into the desired shape.

The present invention therefore deals with the problem of providing improved or at least other embodiments for a method for producing a deformable trim part of the aforementioned type and for such a trim part, which are characterized in particular by a simplified production and / or simplified deformability. In particular, the method should be suitable for curved or complex geometries.

This problem is solved according to the invention by the subject matters of the independent claims. Advantageous embodiments are the subject of the dependent claims.

The present invention is based on the general idea, in a trim piece with a decorative material applied to a deformable support, to divide the decorative material into a plurality of separate decorative material portions such that they are connected together and movable relative to each other over the supports. As a result, the decorative material sections which are held together relative to one another by the carrier can be moved in virtually any relative to one another, so that any desired shape of the decorative part can be achieved. As a result, therefore, a deformability of a trim part is improved and / or simplified. The size and subdivision of the trim portions can be easily adapted to the geometry of the wearer. In addition, by the subdivision of the decorative material in the decorative material sections and the deformable support, caused by the deformation of the trim damage, especially the decorative material, avoided or at least significantly reduced. The trim part can thus be produced and / or deformed in a simplified manner.

According to the idea of the invention, the ornamental material is first applied to the deformable support and fixed to the support for producing the trim part. The fixation of the decorative material on the carrier can be done in any way. In particular, it is conceivable to glue the decorative material to the carrier. Thereafter, for dividing the decorative material in the decorative material sections at least two transverse to the carrier slots are introduced into the decorative material. The respective slot can be visibly introduced into the decorative material. The introduction of the slots in the decorative material takes place in this case such that the slots cut through the decorative material and subdivided into a plurality of separate and fixed to the carrier decorative material sections. The introduction of the slots is further such that the carrier remains connected. This means in particular, that the carrier is not severed by the slots. As a result, the decorative material sections can be moved relative to each other due to the deformable support, so that the trim part is deformable. As a result, an adaptation of the trim part to a component to be decorated can be achieved. This makes it possible in particular to decorate components with complex geometries by means of the trim part, with appropriate damage to the trim part, in particular the decorative material, avoided or at least reduced.

The decorative material may in principle be any suitable for decorating the component. In particular, wood can be used as a decorative material. It is conceivable, for example, to use a wood veneer as a decorative material. It is conceivable, for example, to use a real wood veneer as a decorative material to make the appearance of the trim high-quality.

Preferably, the slots are introduced from the side facing away from the carrier of the decorative material in the decorative material. In this way, damage to the carrier and / or the severing of the carrier can be effectively avoided.

The at least two slots can in principle each have an arbitrary shape. In this case, embodiments are advantageous in which regularly arranged slots are introduced into the decorative material. As a result, the trim part can be adapted to a variety of components with different geometries.

The respective slot can be introduced in any manner in the decorative material. In this case, at least two such slots can be introduced simultaneously and / or at least two such slots successively in the decorative material. For introducing the respective slot in the decorative material can be used any tools. For this purpose, a cutting device, in particular a cutting plotter can be used. Likewise, the slots can be introduced by cutter and / or laser in the decorative material. Here, the introduction of the respective slot in the decorative material can be controlled by a control device in order to bring the desired shape and / or number and / or density and / or a desired course of the slots in the decorative material can.

The carrier may in principle be made of any material, provided that it is deformable in the context of the desired deformation of the trim part, which depends in particular on the geometry of the component to be decorated. It is advantageous in particular to use a fleece, in particular laminating fleece, having carrier.

During the deformation of the trim part into the desired shape, the slots preferably remain unfilled so that the trim material sections can be moved relative to one another in a simplified manner. It is understood, however, that at least one such slot can be filled after deformation of the trim part.

It is conceivable, for example, that the trim part provided with the slots is deformed into a predetermined shape and then coated. At least one such slot can be at least partially filled by the coating. For coating the trim part, in particular the decorative material, advantageously plastics and / or synthetic resins are used, which are preferably transparent, so that the decorative material remains visible from the outside. These include, for example, polyurethanes (PU) and / or polymethyl methacrylates (PMMA).

The production of the trim part can be made such that the slots are made invisible after the molding of the trim part in the desired shape. For this purpose, the slots can be processed in accordance with color. In particular, it is conceivable to fill the slots in such a way that they become invisible.

It is also conceivable that the trim part in the region of such a slot to increase the visible color contrast of the slot is processed in color, so that the visibility of the slot is increased or improved. For this purpose, the corresponding edges of the decorative material sections can be processed in color. It is also conceivable to color the carrier accordingly and / or to use a colored carrier. In this case, the carrier in particular has such a color, which differs from the color of the decorative material. As a result, the color contrast in the region of the slot is increased.

As mentioned above, the slots can be inserted in the decorative material in a uniform, regular manner. In this way, in particular similar and / or the same decorative material sections can be realized. In this case, the respective slot may have a linear course or a curved course and / or a broken course. Of course, this is also conceivable that at least one such slot initially has a linear course and then a curved and / or broken course or vice versa.

The introduction of the slits in the decorative material and thus the subdivision of the decorative material in the Ziermaterielabschnitte may be adapted to the geometry of a component to be decorated. This means that the slots are introduced into the decorative material in such a way that a subsequent deformation of the trim part results in a desired, adapted to the component shape of the trim part results, this deformation of the trim part is preferably done without damage. This is done in particular by a suitable choice of the course and / or the density and / or the number.

As a decorative material in particular wood veneers are used, as they are already used in the automotive sector. These veneers may have material thicknesses of 0.3 to 1 mm, preferably 0.4 to 0.7 mm. The slots or grooves are guided solely by the veneer, not by the underlying fleece or not in the carrier, which serves to stabilize the veneer. The slot or groove depth is depending on the thickness of the decorative material or wood veneer 0.1 to 0.8 mm, preferably 0.1, -0.2 mm. The residual thickness of the decorative material in the slot is thus at least 0.1 mm.

The decorative material, in particular the veneer with slots or grooves preferably forms a reticulated pattern, wherein the slots or grooves intersect and circumscribe areas of different sizes. The surfaces are preferably 2-30 mm by 2-30 mm or 4 to 900 mm ^{2 in} size.

In this way, in particular rectangular and / or square and / or triangular etc. decorative material sections can be realized. Preferably, different shapes are formed with different surface area. Conveniently, the trim portions in the areas that are later subjected to a higher deformation, smaller than in the areas that remain flat, or should have little deformation. Similarly, in these areas, the slots or benefits are closer together.

In general, arbitrary patterns of the slots can be introduced into the decorative material so that the corresponding decorative material sections can each have an arbitrary shape and / or size. Such patterns include, in particular, criss-cross patterns, curved patterns and blends thereof.

In a further embodiment of the invention, the pattern of slots or grooves are highlighted, in particular colored. The slits or grooves are blackened, limed or pickled as in pore structures in the wood and thus set in color. For this purpose, pore filler pastes and powder, or possibly putties may be used. The order can be carried out by rubbing or rubbing with, for example, a bristle brush, polishing bales or the like and subsequent filling. Depending on requirements, the job and the surface cleaning can be repeated several times. This is especially useful for coarse-pored wood. To achieve the additional effects, a colored laminating fleece can also be used, or a colorless one can be dyed later.

The trim part according to the invention or the trim part produced according to the invention can be used in any area. It is conceivable to use the trim part in a vehicle. In this case, the trim part can be mounted on a dashboard of the vehicle and adapted to the shape or the geometry of the dashboard. It is conceivable that the trim part by attaching to the component to be decorated, ie in particular on the dashboard, to deform and bring in the desired shape. It is also conceivable to shape the trim part prior to attachment to the component to be decorated in the desired, adapted to the geometry of the component shape and then attach to the component.

It is understood that in addition to the method for producing such a trim part and such a trim part of the scope of this invention belongs.

Other important features and advantages of the invention will become apparent from the dependent claims, from the drawings and from the associated figure description with reference to the drawings.

It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.
