Abstract

The invention relates to a trim part (1), in particular interior trim part, for a vehicle (3), wherein the trim part at least partially has a wave-shaped structure (7) with elevations (9) and depressions (11) such that the wavy structure (FIG. 7) at a force - for example, a side impact - collapses and a burden, for example, a side impact, distributed such that it does not break the Zuziehgriff armrest (5) of the trim panel comes.

Description

The invention relates to a trim part for a vehicle and a vehicle.

In a side crash, the door inner panel of a vehicle is heavily deformed toward the interior. No parts may break or protrude sharp objects into the interior or stand. Especially the pull-handle of the armrest often presents a particular risk here, since it has to be firmly and rigidly connected for the sake of the desired stability. Therefore, a side impact also often results in breakage in the area where the door trim is most deformed.

To reduce the risk for passengers of the vehicle by broken parts, it is state of the art to secure the door panel in the critical fracture areas by crash hooks or tethers and thus to prevent the release of parts or to prevent their entry into the interior. It is also state of the art, in order to influence the bending behavior and stiffness, in door panels, in particular armrests, introduce honeycomb weakenings, so that they can be selectively deformed.

From the German patent DE 10 124 036 C2 goes out a trim panel, which is attached to the interior of the facing side of a body part of motor vehicles. The cowling has at least one deformable by the action of an external force deformable portion which is provided to absorb impact energy when transferred to a deformed state, wherein the carrier layer is formed in the region of the deformable portion of a seen with respect to the interior outer deformation part , an inner deforming part and a step flank located therebetween, and that the outer deforming part, the inner deforming part and the step flank change their tendency to absorb energy when the external force is applied.

Furthermore, from the German Offenlegungsschrift DE 10 259 592 A1 a trim part of a door or side wall of a motor vehicle, with a deformable armrest, which occupies a release position when loaded on the side and is connected to a laterally movable support element. To create a trim panel, the armrest is laterally reversible movable, it is disclosed to produce the armrest of a flexurally elastic or pliable membrane. This creates the problems already described above.

The invention is therefore an object of the invention to provide a trim part for a vehicle and a vehicle, said disadvantages do not occur.

The object is achieved by providing the subject matters of the independent claims. Advantageous embodiments will become apparent from the dependent claims and the embodiments disclosed below.

The object is achieved in particular by providing a trim part, in particular an interior trim part, for a vehicle, wherein the trim part at least partially has a wave-like structure with elevations and depressions, such that the wave-shaped structure folds up when a force is applied - for example a side impact - and a load, for example, a side impact, distributed so that it does not come to the breakage of the trim part. This has the particular advantage that in the area in which the lining part experiences the greatest bending, a wave structure is deliberately introduced in such a way that it folds up during bending and distributes the stress so that it does not break the component. As a result, it is prevented, in particular, that the passengers of the vehicle are at risk of sharp and broken components. By adapting the wavy structure in terms of size and length, the necessary bending behavior of the trim part can be well influenced and controlled. In the event of a crash, there are no breaks and no open and / or sharp edges. Depending on the design of the wave-shaped structure and load case can be made of a simpler material. Subsequent changes to the tool required for the production of the trim part are easy to implement, especially in terms of wall thickness and slots. It is preferably provided that the covering part consists of a support carrier and a visible side, wherein preferably the support carrier has the wave-shaped structure. Alternatively or additionally, it is also possible that the visible side has the wave-shaped structure. Alternatively or additionally, it is also possible that the support carrier and the visible side have the undulating structure.

For the purposes of the present invention, the term "support beam" is to be understood as a component which imparts structural stability to the trim part.

For the purposes of the present invention, the term "wave-shaped" is not intended to be exclusively a rounded wave-like shape but, for example, a zigzag-shaped one as well trapezoidal or a rectangular shape, to be understood.

According to a first development of the invention, it is provided that the covering part has a closing handle armrest, a curb, a midfield and a base support, wherein at least one of the components of the trim part, which is selected from a group consisting of Zuziehgriff armrest, curb, midfield and basic carrier, which has wave-shaped structure. This makes it possible in a targeted manner to be able to form areas of the trim part, which must have a particularly high structural integrity and stability, accordingly.

In the context of the present invention, the term "curb" is understood to mean an upper part of a trim part, in particular an interior trim part, in the assembled state.

For the purposes of the present invention, the term "midfield" is understood to mean a middle part of a trim part, in particular an interior trim part.

For the purposes of the present invention, the term "base support" is understood to mean a lower part of a trim part, in particular an interior trim part, in the assembled state.

According to a development of the invention, it is provided that the wave-shaped structure has slots in the elevations and / or depressions. In this way, it can be achieved, in particular, that the behavior of the pull-handle armrest in the event of a crash can be specifically influenced.

According to one embodiment of the invention, it is provided that the elevations and / or depressions of the wave-shaped structure have a deflection from a zero crossing - in other words that the elevations and / or depressions of the undulating structure have an extension - which in relation to a wall thickness of the wavy Structure between 50% and 300%, in particular between 100% and 250%, particularly preferably between 150% and 200%. This has the particular advantage that the breaking behavior of the closing handle armrest can be influenced by changing the wall thickness.

According to a development of the invention, it is provided that a wall thickness of the wave-shaped structure is between 1 mm and 10 mm, preferably 3 mm and 7 mm, particularly preferably 4 mm and 6 mm.

According to a development of the invention, it is provided that, in an installed position of the trim part, the elevations and / or depressions of the wave-shaped structure extend parallel to the vehicle transverse direction. In other words, it is preferably provided that, when viewing the elevations and / or depressions, "ridges" of the elevations and "valleys" of the depressions extend parallel to the vehicle transverse direction. Or alternatively described, it is preferably provided that an amplitude direction of the wave-shaped structure is aligned parallel to the vehicle vertical direction. As a result of this orientation of the wave-shaped structure relative to the vehicle transverse direction and thus to the impact vector of a side impact, it was possible in particular to achieve the positive effect, that is to say a prevention of a break in the pull-handle armrest.

In connection with the present invention is to be understood by the passage "parallel to the vehicle transverse direction" with respect to the wavy structure that individual waves, that is, the elevations and depressions are arranged parallel to the vehicle transverse direction and in particular individual waves are not aligned parallel to the vehicle vertical direction ,

According to one embodiment of the invention, it is provided that the covering part, in particular the Zuziehgriff armrest, the curb, the midfield and / or the base support is made of a material or having this material, wherein preferably the material is a press-deformed pulp and / or a Plastic is, wherein the plastic is preferably selected from a group consisting of polycarbonate-acrylonitrile-butadiene-styrene copolymer (PC-ABS) and acrylonitrile-butadiene-styrene copolymer (ABS).
