There are evenly distributed snap hook connections on the inside of the outer shell and provided on the outside of the inner shell. On a side facing the viewer, a front ring is provided, which covers a transition between the inner shell and the outer shell and is locked to the outer and / or the inner shell.

It is an object of the present invention to provide a fastening arrangement, which is improved over the prior art, of a design component on at least one cover and / or frame element and an improved method for producing such a fastening arrangement

specify.

The object is achieved by a

Fastening arrangement of a design component on at least one cover and / or frame element with the features of claim 1 and a method for producing a fastening arrangement with the features of claim 12.

In a mounting arrangement of a design component on at least one cover and / or frame element according to the invention at least one rear-shaped or shaped retaining element of the design component in a correspondingly shaped recess of a first cover and / or frame member positively and / or non-positively.

In this case, the retaining element or are preferably a plurality of such Holding elements arranged on a rear side of the design component and surmount / project beyond the back.

In this way, a play-free and vibration-resistant arrangement of a design component on the first cover and / or frame element is made possible. As a result, a noise development between the design component and the first cover and / or frame element is advantageously avoided.

Furthermore, a quality impression of a fastening arrangement between the design component and the first cover and / or frame element is significantly improved.

The at least one retaining element is or preferably the retaining elements are advantageously at least partially, preferably at the ends bent at a free, repellent from the design component end, so that the holding element or the holding elements have a hook-shaped configuration. This fold, which forms the hook-shaped formation, enables a secure form-fitting attachment of the design component by engagement of the hook-shaped formation on the first cover and / or frame member.

The at least one recess or preferably the recesses of the first cover and / or frame element is / are expediently formed corresponding to a cross section of the respective holding element of the design component, so that the holding element is arranged and held positively in the respective recess. Furthermore, in this way the recesses bounding regions of the first cover and / or frame member to the respective holding element, so that a frictional engagement and thus also a non-positive connection between the design component and the first cover and / or frame element is trained. This makes the backlash-free and vibration-resistant

Attachment of the design component on the first cover and / or

Ensures frame element, so that relative movements between the design component and the first cover and / or frame element, which could lead to disturbing noises, such as rattling, squeaking or creaking, are avoided.

The first cover and / or frame element is expediently designed to be flexible at least in sections in an area surrounding the respective recess. As a result, a simple arrangement of the design component on the first cover and / or frame element is made possible without damaging the respective retaining element, because for insertion of the retaining element into the corresponding recess, this can be increased, for example by means of a corresponding assembly tool, by pulling the flexible region outwards is, away from the recess, so that the recess widens. After insertion of the retaining element in the recess, the assembly tool is then removed, so that the flexible area elastic

deformed back, so that the recess assumes its original size, whereby the retaining element is held in a form-fitting manner in the recess and is preferably also held in a non-positive manner, since

Regions of the first cover and / or frame member, which limit the recess to create the holding element.

Furthermore, it is expedient in the flexible area in each case at least one holding means which corresponds to one

Mounting tool is formed, arranged. At this holding means, the mounting tool is to be used to widen the recess. In this way it is ensured that the recess is to be widened without damaging the first cover and / or frame element by the assembly tool and without the design component and its respective To damage retaining element during insertion into the recess by the mounting tool.

On an opposite side of the recess of the flexible area, in an advantageous embodiment, a reinforcing and supporting element is arranged in or on the first covering and / or frame element. Such a reinforcing and supporting element may be formed, for example, as a plurality of rib-shaped stiffening elements. By reinforcing and supporting element a stiffening of the recess is achieved, so that, for example

Damage and deformation of the first cover and / or

Frame member and the design part, in particular of the respective holding element of the design component, are avoided during a formation of a material connection between the respective holding element and the first cover and / or frame member. The cohesive connection is formed for example by hot-bonding and / or hot stamping. In this case, the respective holding element by the respective reinforcing and supporting element is at least

partially held and supported.

The first covering and / or frame element is expediently arranged on a second covering and / or frame element. In this case, the second cover and / or frame element preferably surrounds the first cover and / or frame element at least in sections such that the flexible region or the flexible regions of the first cover and / or frame element is under or supported such that a Movement of the flexible region or the flexible regions after assembly of the first cover and / or frame member on the second cover and / or frame member and preferably even during assembly is reliably prevented. In this way, if the cohesive connection between the respective holding element and the first cover and / or frame element during assembly of the first cover and / or frame member is formed on the second cover and / or frame member, a

Stiffening of the recess also in the flexible area of the respective

Recess achieved, so that damage and deformation of the first cover and / or frame member and the design component, in particular the respective holding member of the design component, are avoided during the formation of the material connection between the respective holding element and the first cover and / or frame member. In addition, this is after assembly, d. H. during a service life of the mounting arrangement, for example in a vehicle, a widening of the recess and a release of the respective

Holding element prevents the first cover and / or frame member.

The design component is preferably designed as a chrome ring or chrome-plated annular or partially circular component which surrounds a display unit at least in sections. The first cover and / or frame element is expediently designed as a front mask of the display unit and the second cover and / or frame element as the rear cover of the display unit. By means of the thus formed

Fastening arrangement is thus a high quality and stable

Display unit formed.

In the inventive method for producing the

Mounting arrangement is at least one holding element or are preferably used a plurality of holding elements of the design component in the respective correspondingly shaped recess of the first cover and / or frame member. In this way, a play-free and vibration-resistant arrangement of a design component on the first cover and / or frame element is made possible. As a result, a noise development between the design component and the first cover and / or frame element is advantageously avoided.

To make this process easier and more time-consuming

To avoid bending operation of the inflexible holding elements of the design component, are advantageously the flexible area or the plurality of flexible areas of the first cover and / or

Frame member by means of a mounting tool which engages a respective corresponding holding means, reversibly deformed. This deformation takes place such that an opening cross-section of the recess is increased. In this case, the opening cross section of the recess is increased such that the bent end of the holding element can be guided. In this case, the recesses can be widened successively by means of the assembly tool in several recesses to the

Retaining elements after expansion in the respective recess

introduce, or more or all recesses can be widened simultaneously by means of a mounting tool which acts on a plurality of holding means, or by means of a plurality of assembly tools, thereby to be able to simultaneously introduce the corresponding holding elements of the design component in the respective recess.

After carrying out the bent end of the holding element and the removal of the mounting tool, the flexible area resumes its original shape. This reduces the

Opening cross section of the recess on its output, which corresponds to the cross section of the retaining element. Thus, the bent end of the retaining element is arranged behind the first covering and / or frame element and held in such positive and / or non-positive.

By reducing the opening cross section of the recess to its output size, the recesses surrounding areas of the first cover and / or frame element to the holding element, whereby it is frictionally held frictionally. For this purpose, it is advantageous that the opening cross-section is formed corresponding to a cross section of the holding element in the recess arranged in the region of the holding element or, for example, also slightly smaller than this cross section of the holding element is formed, thereby further pressing the recess surrounding areas of the first Cover and / or frame element to the

Retaining element and thus achieve an even stronger positive connection.

After this assembly process, the formation of a material connection between the at least one holding element or preferably between the plurality of holding elements of the design component and the first cover and / or frame element takes place. The formation of such a material connection can for example by means of a

Hot glue or a hot stamping process done. As a result, in addition to the positive and / or non-positive connection, a permanently very strong cohesive connection between the holding elements of the design component and the first cover and / or frame element is produced, so that over a period of use of the fastening assembly away a release of the design component of the first cover - And / or frame element is prevented. In particular, this way

Relative movements between the design component and the first cover and / or frame member, which can lead to unwanted noise, over the entire service life of the mounting assembly prevented.

Particularly preferably, the formation of the cohesive takes place

Connection between the holding elements of the design component and the first cover and / or frame member during assembly of the first cover and / or frame member on the second cover and / or frame member. In this way, the second cover and / or frame element as a support for the first cover and / or

Serve frame member and thereby prevent deformation of the first cover and / or frame member during the formation of the cohesive connection. In addition, this is a fast

Making possible, since the assembly of the first cover and / or frame member on the second cover and / or frame member and the formation of the material connection takes place in a common operation.

The at least one holding element or the plurality of holding elements of the design component is / are preferably by means of the reinforcing and supporting element or by means of the reinforcing and

Support elements of the first cover and / or frame member during the heat-bonding or hot stamping process at least partially held and supported. Through the reinforcement and

Supporting element, a stiffening of the respective recess is achieved, so that, for example, damage and deformation of the first cover and / or frame member and the design component, in particular the respective holding element of the design component, during the formation of the material connection between the respective holding element and the first cover and / or frame element is avoided. Furthermore, the at least one flexible will advantageously be / are

Area or the flexible areas of the first cover and / or frame member under or supported by the second cover and / or frame member such that movement of the flexible areas during and after assembly of the first cover on the second and / or

Frame element is securely prevented.

Embodiments of the invention are explained in more detail below with reference to drawings.

Fastening arrangement and

Fig. 2 schematically shows a perspective view of a

Assembly process of a design component on a first cover and / or frame element. Corresponding parts are provided in all drawings with the same reference numerals.

1 shows schematically a sectional view of a fastening arrangement 1 according to the invention. Such a fastening arrangement 1 comprises at least one design component 2, a first cover and / or

Frame element 3 and a second cover and / or frame member 4th

Design component 2, first cover and / or frame member 3 and second cover and / or frame member 4 are preferably part of a

conventional display unit, not shown, on the relevant operating data of the vehicle can be displayed.

In order to achieve an optically high-quality appearance of the display unit, it is at least partially surrounded by the design component 2 on a front facing the vehicle user. That's it

Design member 2 formed corresponding to an outer periphery or a portion of the outer periphery of the display unit.

The design component 2 is preferably designed as a chrome ring or a chrome-plated annular or partially circular component which surrounds the display unit at least in sections.

A front side 5 of the design component 2 has a rounded, semicircular or wavy surface formation. A rear side 6 of the design component 2 is substantially planar.

On the back 6 of the design component 2 holding elements 7 are arranged or formed. In this case, the holding elements 7 project beyond the rear side 6. Design component 2 and holding elements 7 are preferably formed in one piece. The holding elements 7 are folded at least in sections, preferably at the ends on a free, repellent from the design part 2 end 8, so that the holding elements 7 have a hook-shaped configuration. A region 9 between the fold 10 and the back 6 of the

Design components 2 is formed in a straight line.

The first cover and / or frame element 3 is preferred as

conventional front mask of the display unit formed. The

Design component 2 is arranged by means of at least one retaining element 7 in a correspondingly shaped recess 1 1 of the first cover and / or frame member 3 positive and non-positive.

The recesses 1 1 of the first cover and / or frame member 3 are corresponding to a cross section of the respective

Holding member 7 of the design part 2 is formed, so that the

Retaining element 7 is arranged and held in a form-fitting manner in the respective recess 11. The recess 1 1, for example, has a

rectangular cross section on. In this case, the design component 2 lies with its rear side 6 essentially on the entire surface on the first cover and / or frame element 3.

The first cover and / or frame element 3 is in a

Recess 1 1 surrounding area 12 formed at least partially flexible. Furthermore, in each case at least one retaining means 13, which corresponds to one in FIG. 2, is in this flexible region 12

illustrated assembly tool 14 is formed arranged.

To form the flexible region 12, for example, a cross-sectional tapering 18 in the first cover and / or frame element 3 is formed on each side of the holding means 13. At one of the flexible region 12 opposite side 15 of the recess 1 1, a reinforcing and supporting element 16 is arranged in or on the first cover and / or frame member 3. Such a reinforcing and supporting element 16 may be formed, for example, as a plurality of rib-shaped stiffening elements. In this case, the reinforcing and supporting element 16 is formed corresponding to the rectilinear region 9 of the respective holding element 7.

The second cover and / or frame member 4 is preferably formed as a rear cover, housing or housing portion of the display unit.

The first cover and / or frame element 3 is arranged on the second cover and / or frame element 4. In this case, the second cover and / or frame member 4 surrounds the first cover and / or frame member 3 at least in sections such that the flexible portions 12 of the first cover and / or frame member 3 are under or supported such that movement of the flexible Areas 12 after assembly of the first cover and / or frame member 3 on the second cover and / or frame member 4 is reliably prevented. For this purpose, the second cover and / or frame member 4, for example, correspondingly shaped, in particular inflexible, wall sections 17 or formations, which are laterally arranged positively on the flexible portions 12.

FIG. 2 schematically shows a perspective view of a mounting operation of the design component 2 on the first cover and / or

Frame element 3. In the method for producing the fastening arrangement 1, the holding elements 7 of the design component 2 are correspondingly in the

shaped recesses 1 1 of the first cover and / or

Used frame element 3. In order to facilitate this process and to avoid a laborious bending operation on the inflexible holding elements 7 of the design component 2, the flexible regions 12 of the first cover and / or frame element 3 by means of

Assembly tool 14 which engages the corresponding holding means 13, reversibly deformed. For this purpose, the assembly tool 14 is hook-shaped in the example shown here, to the respective

Attack holding means 13 and to be able to pull it so that the recess 1 1 expands.

This deformation takes place in such a way that an opening cross-section of the recess 11 is increased. The opening cross section of the

Recess 1 1 increases such that the folded end 8 of the support member 7 can be passed. After performing the bent end 8 of the holding member 7 and the removal of the mounting tool 14, the flexible portion 12 assumes its original shape.

As a result, the opening cross-section of the recess 1 1 reduces to its initial size, which corresponds to the cross-section of the holding element 7, in particular in its rectilinear region 9. Thus, the bent end 8 of the retaining element 7 is arranged behind the first covering and / or frame element 3. As a result, the design component 2 is held positively and / or non-positively on the first cover and / or frame element 3.

After this assembly process, the formation of a material connection between the holding elements 7 of the design part 2 and the first cover and / or frame element 3. The formation of such cohesive connection can be done for example by means of a conventional hot-glue or a hot stamping process.

Particularly preferably, the formation of the cohesive takes place

Connection between the holding elements 7 of the design component 2 and the first cover and / or frame element 3 during assembly of the first cover and / or frame member 3 on the second cover and / or frame member 4th

The holding elements 7 of the design component 2 are by means of the reinforcing and supporting elements 16 of the first cover and / or

Frame member 3 at least partially held and supported during the hot-glue or hot stamping process.

Furthermore, the flexible portions 12 of the first cover and / or frame member 3 are so from the second cover and / or

Under or supported frame member 4 that a movement of the flexible portions 12 during and after assembly of the first cover and / or frame member 3 on the second cover and / or

Frame member 4 is reliably prevented.

In this way, a play-free and vibration-resistant fixation of a design component 2 on a cover and / or frame member 3 is possible. As a result, a noise development between the design component 2 and the cover and / or frame element 3 is advantageously avoided.

Furthermore, due to the reduced gap dimensions and tolerances, a quality impression of a fastening arrangement 1 between

Design component 2 and cover and / or frame element 3 significantly improved. Particularly advantageously, relative movements are between

Design component 2 and cover and / or frame member 3 during operation of the display unit prevents or at least significantly reduced.
