The present invention relates to a decorative element, a dashboard, notably for a motor vehicle, and a method for manufacturing a decorative element.
Decorative elements are known, notably for dashboards and in particular for motor vehicles.
Moreover, it is known practice to provide a chromium plating on an element intended to be attached to a vehicle, notably a motor vehicle. Such an element is—for example—known from the publication U.S. Pat. No. 6,279,974 B1.
Such an element provided for a chromium plating provides for the part to be chrome plated to be first of all manufactured, for the chrome plating step then to be performed, and, during a subsequent step, for such a chrome-plated part to be attached to a non-chrome-plated part.
The consequence of such a manufacturing method is that assembly tolerances may have a negative effect on the esthetic appearance of such a decorative element.
The aim of the present invention is notably to overcome the drawbacks of the prior art, and notably those cited above, and also to propose a decorative element and a dashboard of a vehicle which can be produced simply and efficiently and which has an advantageous esthetic appearance.
According to the invention, this aim is achieved by a decorative element, notably for use associated with a dashboard of a motor vehicle, the decorative element comprising a first part and a second part, the first part of the decorative element being made of a first non-transparent material, the first material bearing a decoration layer, the second part of the decorative element being made of a second transparent or diffusing material (allowing for the passage of light), the first part of the decorative element and the second part of the decorative element being produced in a single piece.
Through such a production of the decorative element, it is advantageously possible to reduce or eliminate the assembly tolerances between the first part of the decorative element and the second part of the decorative element. This makes it possible to enhance the esthetic appearance of the decorative element, notably when the second part of the decorative element is illuminated.
A preferred refinement of the invention lies in the fact that the first part of the decorative element and the second part of the decorative element are produced via a two-stage injection molding.
According to a preferred embodiment of the decorative element according to the present invention, the first part of the decorative element and the second part of the decorative element are produced via a two-component injection molding.
Through such productions of the inventive decorative element, it is advantageously possible to minimize the efforts in manufacturing the decorative element and to minimize the assembly tolerances.
A preferred refinement of the invention lies in the fact that the first material comprises
polyamide (PA), and/or
acrylonitrile butadiene styrene (ABS), and/or
polycarbonate+acrylonitrile butadiene styrene (PC-ABS), and/or
polycarbonate (PC),
or a composition of these materials.
Through such a production of the inventive dashboard, it is advantageously possible to make the first part of the decorative element capable of being covered by a decoration layer, notably a layer of chromium.
According to a preferred embodiment of the decorative element according to the present invention, the second material comprises polymethyl methacrylate (PMMA) or polycarbonate (PC) as transparency or diffusing variant.
Through such a production of the inventive dashboard, it is advantageously possible to provide the second part of the decorative element such that the second part is not covered by the decoration layer.
A preferred refinement of the invention lies in the fact that the decoration layer is a layer of chromium.
According to a preferred embodiment of the decorative element according to the present invention, the first material is chosen to be easily covered by the decoration layer in a decoration layer application process (galvanoplasty type) and the second material is chosen such that, in the decoration layer application process, the second material is not covered by the decoration layer.
The present invention also relates to a motor vehicle dashboard comprising at least one inventive decorative element.
Through such an embodiment of the display method, it is advantageously possible to increase the level of safety of a vehicle because the user can concentrate on the important information and is not distracted from the main information by a multitude of information presented and/or by different positions of the information.
A preferred refinement of the invention lies in the fact that the dashboard comprises a display means, the display means having a display area, and the display area being at least partially surrounded by the decorative element.
Through such an embodiment of the display method, it is advantageously possible to produce a display that has an advantageous esthetic appearance.
The present invention also relates to a method for manufacturing an inventive decorative element, the method comprising the following steps:
in a first step of the method, the first part and the second part are produced via a two-stage injection molding or via a two-component injection molding, and
in a second step of the method, the decoration layer is applied selectively onto a surface of the first part.
Other features and advantages of the invention will become apparent from reading the following description of a particular nonlimiting embodiment of the invention.
The invention will be better understood from the following description, which relates to preferred embodiments, given as nonlimiting examples, and explained with reference to the appended schematic drawings in which:
As
In the example shown in
The first part 2 of the decorative element 1 comprises a first material and the second part of the decorative element 1 comprises a second material. The first material is different from the second material in terms of its physical and/or chemical properties. For example, the first material comprises
polyamide (PA), and/or
acrylonitrile butadiene styrene (ABS), and/or
polycarbonate+acrylonitrile butadiene styrene (PC-ABS), and/or
polycarbonate (PC),
or a composition of these materials.
It is also possible for the first material to comprise a composition of a number of these materials.
For example, the second material comprises polymethyl methacrylate (PMMA) or polycarbonate (PC) as transparency or diffusing variant.
The first material is preferably a material that has a high susceptibility for a decoration layer (indicated in
The second material is preferably a material on which a decoration layer does not hold, that is to say, when the decorative element 1 (before being subjected to the decoration layer application process) is treated so as to produce the decoration layer, the decoration layer is not deposited on a surface of the second part (or the second material) of the decorative element 1.
In
In all the variants of the present invention, the second material is preferably a material which is transparent. Moreover, according to the present invention, it is possible (and represented in
It is preferred for the two parts 2, 3 of the decorative element 1 to be produced via a two-stage injection molding or via a two-component injection molding. It is also possible for the decorative element to be produced via an injection molding with three (or more) stages or via an injection molding with three (or more) components.
