Description

The invention relates to a method for producing a decorative element, in particular a Holzzierelements. Furthermore, the invention relates to such a decorative element and the use of such a decorative element.

Decorative elements are used for example as trim parts in motor vehicles. Such decorative elements may cover speakers and must therefore have recesses through which the sound of the speakers can pass. Holzzierelemente are usually not stamped, so that the introduction of a plurality of recesses in such a Holzzierelement is not economical. For this reason, a speaker grille is usually used instead in the Holzzierelement, as for example from the DE 690 10 612 T2 is known.

In decorative elements made of plastic, the injection mold can be adjusted accordingly, so that the decorative elements have a plurality of recesses, as for example from the DE 10 2011 078 234 A1 is known. From the US 2003/0066596 A1 Decorative elements are known in which on a carrier substrate, a decorative layer of fabric is applied and these two layers are punched.

The present invention has for its object to provide an improved or at least other embodiment of a manufacturing method for a decorative element with a plurality of recesses, which is characterized in particular by a simpler and more cost-effective production.

This object is achieved by the backrest of the independent claims. Advantageous developments are the subject of the dependent claims.

The invention is based on the general idea of making a thin layer of wood stampable by applying this layer of wood to a carrier material which can be punched. As a result, a plurality of recesses can be introduced into the decorative element by means of a single method step. It is expedient that a layer of wood is applied to a stampable carrier material to form a composite, and the composite of the layer of wood and the carrier material is punched to introduce a plurality of recesses in the centering element. In this way, a plurality, in particular all required, recesses can be introduced into the decorative element with a single punching tool. The production of the decorative element is thereby considerably facilitated. Consequently, both time and cost can be saved.

A favorable possibility provides that aluminum is used as the carrier material, in particular an aluminum plate. Aluminum is excellently punched. Also the combination of the situation wood and the aluminum is punched. Consequently, the recesses need not be drilled individually in the trim element but can be introduced by means of a single punching tool.

A particularly favorable possibility provides that a wood veneer is used as a layer of wood, in particular an open-pored wood veneer. As a result, only a small volume of expensive wood is needed. Usually expensive and noble and beautiful-looking wood types are used in decorative elements, so that the saving of the amount of wood leads to a cost reduction.

An advantageous solution provides that the composite is formed, in particular bent. Through the carrier layer, which forms the main part of the stability of the decorative element forming processes, such as bending can be performed. In this way, a more varied design of the decorative element can be made possible.

A particularly advantageous solution provides that the layer of wood is dyed and / or varnished and / or finished. These steps are preferably carried out after the introduction of the recesses and after the forming of the composite. Through these steps, the decorative element receives a particularly valuable visual impression.

Furthermore, the above object is achieved by a decorative element with a layer of wood, which is applied to a carrier material, wherein the decorative element has a plurality of recesses, which pierce the decorative element. This allows speakers, which are arranged behind the decorative element are covered by the decorative element, so they do not interfere with the visual impression. At the same time, the sound generated by the speakers is only slightly disturbed by the ornamental element.

A favorable variant provides that the decorative element is produced by a method according to the above description. As a result, the advantages of the method are transferred to the decorative element on the above description insofar reference is made.

In addition, the above object is achieved by the use of such a decorative element in a motor vehicle, wherein the decorative element a speaker of the motor vehicle covering and sound generated by the speaker through which recesses may pass to propagate in an interior of the motor vehicle. By using such a decorative element in a motor vehicle, a very noble interior with wood look can be achieved without disturbing speaker grille while the visual impression. The fact that the recesses can be punched for the passage of sound, the production cost of such a decorative element are lower than if these recesses would have to be drilled individually. In addition, no separate speaker grille is required thereby, whereby the security, for example, in a head impact, is increased. In addition, the tendency to fragmentation is significantly reduced.

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.

Preferred embodiments of the invention are illustrated in the drawings and will be described in more detail in the following description, wherein like reference numerals refer to the same or similar or functionally identical components.

In each case show schematically:

1 A view of an inventive decorative element,

2 A sectional view through the decorative element 1 along the section line AA.

An in 1 illustrated decorative element 10 is used for example in motor vehicles to cover an interior of the motor vehicle. In particular, the decorative elements 10 improve the look of the interior. Especially noble see decorative elements 10 from, which have a wooden surface. For example, root wood is very popular. In modern vehicles, the quality of the sound generated by the radio is very important. Because of this, many speakers are often installed. Usually, such speakers are covered with speaker grids through which the sound generated by the speakers can pass. However, these speaker grilles significantly disturb the appearance of the interior. For this reason, it is desirable if the decorative element 10 recesses 12 through which sound can pass, which is generated by the speakers.

For this purpose, a plurality of recesses 12 needed, which are located directly above the speaker. Wood can only be punched poorly. In particular, open-pored types of wood, which have particularly high-quality optical properties, in particular a noble appearance, can be poor or do not punch at all.

The ornamental element 10 has a stampable carrier layer 14 on which a layer of wood 16 is up. The composite formed in this way 18 is due to the stampable carrier layer 14 also punched. In such a decorative element 10 can therefore use a punching tool which has a plurality of punches for the recesses 12 has in a single punching step a plurality, in particular all required, recesses in the decorative element 10 be introduced.

The carrier layer 14 preferably has aluminum. Aluminum is particularly easy to punch and, moreover, very light, so that the overall weight of the decorative element 10 remains low.

After the composite 18 from the location wood 16 and the carrier layer 14 was punched, the decorative element can be subjected to further processing steps. In particular, due to the carrier layer 14 made of aluminum, the decorative element to be bent. Due to the malleability of the aluminum and the decorative element 10 be shaped accordingly.

After these forming steps, the situation can be wood 16 be refined, in particular by dyeing or varnishing and / or polishing the wood layer.

As a location wood 16 For example, wood veneer can be used. Preferably optically noble woods are used, for example, walnut or root wood.
