Embodiment Construction
[0016] As can be seen from FIG. 1, the wooden decorative covering includes a wooden veneer 1 that has been provided with a non-woven fabric layer 2. These two layers are already provided with a plastic support layer 3 in the injection mold. It can be seen from Figure 2 that the wooden veneer 1 is very curved. In the case of this large curvature, there is a danger of cracks in the veneer. However, the wooden veneer is stabilized by the non-woven fabric layer 2 in such a way that it can be bent to the extent shown in FIG. 2 without any cracks. Fastening means such as the hooks 4 shown are integrally formed on the plastic support layer 3.

Description
Technical field [0001] The invention relates to steering wheel decorative covering and interior decorative elements according to the preamble of claim 1 and a method for producing them. Background technique [0002] Various methods are known for producing steering wheel decorative covers and interior decorative elements. A method is known from practice to provide a decorative layer which is applied to a support made of wood, wooden material, plastic or metal by means of an adhesive or glue. The disadvantage of this method is that the production of such components requires a lot of operations. In addition, if the element is formed in a spherical form, cracks appear on the finish which can only be deformed to a limited extent. [0003] Furthermore, from DE-A2944797A1, a curved strip used in particular for the interior of a motor vehicle and a method for its production are known. The outer layer of the strip, visible after installation, includes a wooden veneer covering which is app...
