Description

One aspect of the invention relates to an inner container for a household refrigerator. The inner container has a one-piece, U-shaped base body. This is made of metal. With the base body, in particular the inner container, a receiving space is formed, which is designed as a receiving space for food when the inner container is installed in the household refrigerator. The base body has a first side wall, a rear wall and a second side wall. Another aspect of the invention relates to a household refrigerator with an inner container. Yet another aspect of the invention relates to a method for producing an inner container for a household refrigerator.

Inner containers for household refrigeration devices are known. They are usually made of plastic. They can be made in one piece. For example, they can be produced as an injection molded component or by deep drawing.

However, it is also known that an inner container is made of metal. In these exemplary embodiments, however, the inner container is not designed in one piece, but rather is assembled from several individual components. However, it is also known in this context that such an inner container has an angled base body made of metal. In this regard, such an inner container is, for example, from DE 1601868 A1 known.

For example, an angled metal part for an inner container is also made from the US 3410449 A known.

Furthermore, from the CN 215675979 U a container for a household refrigeration device is known, which is constructed in several parts. The inner container can be made of a copper alloy. It has an angled central part which has a rear wall, a top wall and a bottom wall.

It is the object of the present invention to create an inner container for a household refrigerator which has a multi-angled, one-piece base part made of metal and which is functionally improved.

This object is achieved by an inner container, a household refrigeration device and a method according to the independent claims.

One aspect of the invention relates to an inner container for a household refrigerator. The inner container has a one-piece, U-shaped base body. This is made of metal. With the base body, in particular the inner container, a receiving space is formed or delimited, which is designed as a receiving space for food when the inner container is installed in the household refrigerator. The base body has a first side wall, a rear wall and a second side wall.

The base body has at least one coupling elevation. This coupling elevation is integrated into one of the walls. The coupling elevation is intended to be designed for coupling a separate additional component of the household refrigeration appliance. A one-piece, U-shaped base body made of metal is now formed for the inner container, which is integrated and thus formed in one piece with it and additionally has at least one such coupling elevation. This is functionally configured as intended so that an additional component can be attached directly to it. Such a separate additional component of the household refrigerator can thus be stably attached to such a metallic inner container. By integrating such a coupling structure into at least one wall of the metallic base body, the number of components is reduced and stability is increased. The coupling structure in a specific form as a coupling elevation thus enables an exposed orientation and position, so that the additional component can be easily arranged on it and is held mechanically stable. On the one hand, the integrated design of this coupling elevation can save assembly effort compared to a separate coupling elevation, which first has to be mounted on the base body. Likewise, position tolerances can be avoided accordingly. However, the mechanical stability is particularly advantageous if this coupling elevation is integrated into the base body. This means that load-bearing forces can also be absorbed in an improved manner. This is particularly advantageous in combination with the design of the base body made of metal. On the one hand, this already improves the basic structure and the material design, especially with regard to an inner container made of plastic. Since the coupling elevation is also locally integrated and made of metal, the inherent stability and rigidity is also improved.

In one embodiment, the coupling elevation is integrated in at least one side wall of the base body. This means that additional components can also be attached locally to this at least one side wall. In particular, it is formed entirely within a side wall. This also means that the entire geometry of such a coupling elevation is designed to be integrated within the dimensions of the side wall.

In one embodiment, a coupling elevation is formed as an elongated, horizontal elevation. This provides a coupling structure that allows an additional component to be coupled directly to it over a longer path or a longer contact surface. The coupled state is thereby improved and mechanically more stable.

A coupling elevation is viewed in itself as a structure that is formed to be exposed and protruding from the plane in which the wall in which this coupling elevation is formed extends flatly.

In one exemplary embodiment, the coupling elevation is designed as an embossing. This means that it can also be produced with very precise shape. In addition, an embossing can also be produced relatively easily, for example using an embossing stamp.

In one exemplary embodiment, the coupling elevation has an opening which is continuous through the wall in which the coupling elevation is formed. The coupling elevation therefore also has a hole area. This makes the attachment of an additional component even more flexible and variable. Because attachment can then also be made possible on or through the breakthrough. Furthermore, a breakthrough enables a more diverse creation of a geometry of the coupling elevation. This makes it easier to avoid undesirable local material thinning when the coupling elevation is formed from the material of the side wall.

In one embodiment, the coupling elevation is formed completely within the surface of the wall. In particular, the coupling elevation is designed at a distance from the edges of the wall. This means that a coupling elevation is not formed on the edge of the wall, at least in some areas. Thanks to such a coupling elevation that is completely internal to the surface, it can also be created in a very stable and dimensionally stable manner. In particular, additional components can also be reversibly and detachably attached at a distance from an edge of the wall.

In one exemplary embodiment, the coupling elevation has at least one bulge or bulge. In particular, this bulge is U-shaped. This means that this bulge itself is mechanically very stable and therefore designed to be dimensionally stable. In particular, the absorption of corresponding load forces when carrying additional components can be improved.

In one exemplary embodiment, a front edge of a side wall viewed in the depth direction of the inner container is designed as an angled edge region. This angled edge region integrated into the base body increases the inherent rigidity of this wall, especially at this front edge. This shape of the front edge is particularly advantageous in that further additional components can be fastened to this front edge of the side wall in a mechanically stable manner. This front edge therefore also serves as an additional connection or support structure for other components, particularly due to this individual shape.

Preferably, this shape of the angled edge region is formed over at least 50 percent, in particular at least 70 percent, in particular at least 90 percent of the entire length of this front edge.

In one exemplary embodiment, this edge region can be L-shaped in cross section perpendicular to its longitudinal axis, in particular correspondingly angled. On the one hand, such a shape is easy to produce, for example through specific forming. On the other hand, this also enables a very high level of inherent rigidity. The connection of further additional components to such a specific shape of the edge area is therefore simple and also possible with precise positioning.

In one exemplary embodiment it is provided that at least one coupling receptacle is integrated into a freely cantilevered, front L-leg of this L-shape when viewed in the depth direction. This coupling receptacle is intended for coupling with another additional component of the household refrigeration device. This means that another additional component can be connected in a locally specific manner using this coupling receptacle. In one exemplary embodiment, the coupling receptacle can be a breakthrough in this front L-leg. In particular, this coupling receptacle also enables, for example, a snap connection and/or a push-through connection of elements of the additional component to this front L-leg. In this context, it is also possible for this coupling receptacle to have a non-rectilinear opening, for example a C-shaped opening.

In one exemplary embodiment, an upper edge of at least one of the walls, viewed in the height direction of the inner container, can be formed as an angled edge region. In addition or instead of this, a lower edge of at least one of the walls, viewed in the height direction of the inner container, can be formed as an angled edge region. The Win kelung can be seen in particular in a cross section perpendicular to the longitudinal axis of the edge area. In this way, corresponding advantages such as those mentioned above for the front edge can also be achieved. This means that, on the one hand, the stability or rigidity is increased, and on the other hand, the direct connection to other separate walls of the inner container, for example a roof wall and/or a bottom wall, is improved. In particular, in such an exemplary embodiment, an angle part of such an edge region can also serve as a coupling strap for coupling to such a bottom wall and/or a ceiling wall. In this context, plug-in connections and/or stamped connections or the like can be produced by means of an angular part of such an edge region with a bottom wall and/or a ceiling wall.

In one exemplary embodiment, an inside of the base body facing the receiving space, in particular at least one of the walls, can be structured. In addition to or instead of this, such an inside can have an additional color layer, at least in some areas. A color layer can be, for example, a film and/or a coating and/or a print. Powder coating can also be provided.

In one exemplary embodiment, the inner container has further separate walls in addition to this one-piece, U-shaped base body. Such an additional separate wall can be, for example, a ceiling wall and/or a floor wall. These can be connected to the base body accordingly, so that the receiving space is delimited on the one hand by the three walls of the base body, in particular two vertical side walls and a rear wall, and on the other hand by the roof wall and the bottom wall. On the front, this inner container has a loading opening through which stored goods can be introduced into and removed from the receiving space.

Another aspect of the invention relates to a household refrigerator. This is designed specifically for storing and preserving food. The household refrigeration device can be, for example, a refrigerator or a freezer or a fridge-freezer combination device. The household refrigerator preferably has a body. This in particular has an outer housing. An inner container is arranged in the outer housing, as is formed in particular by the above-mentioned aspect or an advantageous exemplary embodiment thereof. The inner container is separate from the outer housing. In addition, the household refrigeration device can have a door. This can be movably arranged on the body and can be provided for closing the receiving space.

Another aspect of the invention relates to a method for producing an inner container for a household refrigerator. The inner container can be designed in particular according to the above-mentioned aspect or an advantageous embodiment thereof.

• - Bereitstellen eines plattenartigen Zuschnitts aus Metall;
• - Erzeugen zumindest einer Ankoppelerhebung in dem Zuschnitt und/oder Erzeugen zumindest eines umgeformten Randbereichs am Zuschnitt;
• - Erzeugen von zwei Biegekanten in dem Zuschnitt, so dass ein U-förmiger, einstückiger Basiskörper des Innenbehälters gebildet ist.

The method has the following steps in particular.

• - Providing a plate-like blank made of metal;
• - Generating at least one coupling elevation in the blank and/or generating at least one reshaped edge region on the blank;
• - Creating two bending edges in the blank, so that a U-shaped, one-piece base body of the inner container is formed.

Such a method can also be used in a specific sequence of steps to produce an improved production in terms of time and with regard to the respective sub-regions of the metallic inner container that are to be produced and which is more tailored to metal processing.

Especially when, in an exemplary embodiment, the coupling elevation and/or a shaped edge region are first created in the preferably flat plate-like blank, this can be carried out more easily with appropriate tools. Since access to the plate-like blank is easier with appropriate tools, more complex shapes can also be integrated and created precisely in this blank. In particular, in the method, the creation of the U-shape of the base body can only be carried out after the creation of a coupling elevation and/or at least one formed edge region. Because then the creation of local structures, in particular at least one coupling elevation and/or at least one reshaped edge region, is already completed and the final shape of the base body can then be carried out more precisely and in line with needs. In this context, the essentially flat design of the plate-like blank can then be produced with very precise bending edges, in particular two parallel bending edges, so that the U-shape with the opposite, in particular parallel side walls and the rear wall can be produced precisely.

Therefore, this sequence of steps is particularly important when producing the inner container, especially if it is locally integrated Having coupling elevations and/or shaped edge areas is particularly advantageous.

In one embodiment, a local, continuous slot can first be created in the plate-like blank. Following this creation of the slot, the coupling elevation can then be formed by shaping at least a surface area of the blank that adjoins this slot from the plane of the blank by reshaping.

In particular, in one embodiment, a U-shaped bulge is created directly adjacent to the slot. As a result, a specific coupling elevation is formed by this U-shaped bulge and the then formed opening that emerges from this initially one-dimensional slot. This sequence of steps can also be used to easily create a geometrically and conceptually very individual coupling survey. Here too, the shape precision can be achieved particularly advantageously and the tearing out of structures in the area of this coupling elevation as well as undesirable material thinning of the metal can be avoided. In particular, not only is the shape precision high, but also the stability of this integrated coupling elevation is particularly high and advantageous.

In a further exemplary embodiment, the coupling elevation can have at least one bent web. This can be formed by punching the wall and bending the punched tab or strip. In particular, this web is bent towards the outside of the wall in which it is formed. It is therefore bent away from the opposite wall of the U-shape. In one exemplary embodiment, an upper web and a lower web in the height direction can be formed. Both can be oriented horizontally and parallel or substantially parallel to each other. You can limit an opening, particularly a slot-like one, in the wall from above and from below. An additional component can be coupled to this coupling elevation, especially the two webs.

Embodiments of an independent aspect of the invention are to be viewed as advantageous embodiments of the other independent aspect. This also applies to the process steps that produce the inner container.

The information “top”, “bottom”, “front”, “back”, “horizontal”, “vertical”, “depth direction”, “width direction”, “height direction” means that the inner container or the inner container is used as intended and positioned as intended Positions and orientations given for the household refrigeration device are given.

Further features of the invention emerge from the claims, the figures and the description of the figures. The features and feature combinations mentioned above in the description, as well as the features and feature combinations mentioned below in the description of the figures and/or shown in the figures alone, can be used not only in the combination specified in each case, but also in other combinations or on their own, without the frame of the invention.

Exemplary embodiments of the invention are explained in more detail below using schematic drawings. Show it:

• 5 an enlarged view of a portion of 4

In the figures, identical or functionally identical elements are given the same reference numerals.

In 1 is a perspective view of an embodiment of a household appliance, shown here as a household refrigerator 1. The household refrigerator 1 has a body 2. The body 2 has an outer housing 3. In addition, the body 2 also has an inner container 4. The inner container 4 is separate from the outer housing 3. It is accommodated in the outer housing 3. In In particular, thermally insulating material is introduced into a gap 5 between the outer housing 3 and the inner container 4.

The inner container 4 delimits a receiving space 6 with walls. The receiving space 6 is intended to hold food. It can be a refrigerator compartment or a freezer compartment.

The inner container 4 has a first side wall 7, an opposite second side wall 8, a rear wall 9, a top wall 10 and a bottom wall 11. In addition, the household refrigerator 1 has a door 12. This is movably arranged on the body 2. It is intended for closing the receiving space 6 at the front.

The inner container 4 has a base body 13, as shown in 2 is shown in perspective in one embodiment. The base body 13 is formed in one piece, in particular manufactured in one piece. He is made of metal. The base body 13 is preferably U-shaped, particularly when viewed in a horizontal plane. Here it has the first side wall 7, the second side wall 8 and the rear wall 9. In particular, the base body 13 can be made from a sheet metal, in particular a steel sheet.

The base body 13 has at least one coupling elevation 14 integrated and thus formed in one piece with it. In particular, several such coupling elevations 14 can be provided in the exemplary embodiment. In the exemplary embodiment, several coupling elevations 14, which are oriented parallel to one another in the depth direction (z direction), can be formed both in the first side wall 7 and in the second side wall 8. For the sake of clarity, only some of these coupling elevations 14 are provided with the corresponding reference numerals. A coupling elevation 14 is intended to directly accommodate, in particular to couple to, an additional component of the household refrigeration appliance 1 that is separate from the base body 13, in particular to the inner container 4. Such additional components can be a variety of components. It is possible that, for example, a shelf, in particular a plate-like partition, which can be arranged in the receiving space 6, can be placed on such coupling elevations 14. It is also possible for a carrier part to be coupled directly to a coupling elevation 14. This separate carrier part is then intended to be intended so that an additional component separate from it can then be arranged.

It can be provided that a coupling elevation 14 is designed to protrude in a raised manner from the plane of the side wall, in particular the side wall 7 and/or the side wall 8.

In one exemplary embodiment, a coupling elevation 14 can preferably be oriented raised from the plane of the side wall 7 in the direction of the opposite side wall 8. In particular, this applies to all coupling elevations 14 of this side wall 7. In one exemplary embodiment, coupling elevations 14, which are integrated in the side wall 8, can be oriented in the direction of the side wall 7, protruding from the plane of this side wall 8.

In another exemplary embodiment, a coupling elevation 14 can preferably not be oriented raised from the plane of the side wall 7 in the direction of the opposite side wall 8, but rather be oriented applied thereto. This applies in particular to all coupling elevations 14 of this side wall 7. They are then designed to be raised towards the outside of the side wall 7.

In a further exemplary embodiment, the coupling elevation 14 can have at least one bent web. This can be formed, for example, by punching the side wall 7 and bending the punched tab or strip. In particular, this web is bent towards the outside of the side wall 7 in which it is formed. It is therefore bent away from the opposite side wall 8 of the U-shape. In one exemplary embodiment, an upper web and a lower web in the height direction can be formed. Both can be oriented horizontally and parallel or substantially parallel to each other. You can limit an opening, in particular a slot-like one, in the side wall 7 from above on the one hand and from below on the other hand. An additional component or a support part for a separate additional component can be coupled to this coupling elevation 14, in particular the two webs.

In the exemplary embodiment shown, the coupling elevations 14 have elongated, horizontal elevations. Their longitudinal axes preferably extend in the depth direction.

As can be seen, the coupling elevations 14 are formed completely within the surface of the side wall 7 and/or the side wall 8. This means that they are preferably formed at a distance from the upper edges and/or lower edges and/or front edges and/or rear edges of the side wall 7 and/or the side wall 8 in the surfaces of these side walls 7 and/or 8.

A coupling elevation 14 can in one embodiment, as shown in the enlarged view in 3 is shown, be formed by an embossed portion 15, for example. This embossed portion 15 can be formed, for example, as a U-shaped bulge. In the exemplary embodiment shown here, the coupling elevation 14 also has an opening 16. This is a strip-shaped opening that is open downwards and/or to the side. It therefore represents a hole area in the side wall 8. In particular, in one exemplary embodiment, this opening 16 is covered by the area 15 from above in a quasi roof-like manner.

The further coupling elevations 14 can also be designed accordingly. In particular, in one exemplary embodiment, this partial area 15 can be raised towards the receiving space 6, for example embossed or punched and bent. In another exemplary embodiment, this partial area 15 can be turned away from the receiving space 6 and thus raised outwards, for example embossed or punched and bent.

In one exemplary embodiment, a front edge 17 of the side wall 7 is formed as an angled edge region 18. In particular, this edge region 18 is formed with an L-shape in a cross section, in particular in a horizontal section (spanned by the xz plane), and thus perpendicular to its longitudinal axis oriented in the height direction. For this purpose, an L-leg 18a oriented in the width direction (x direction) is created. Another L-leg 18b is oriented in the depth direction. This front L-leg 18b is an L-shaped leg that projects freely towards the front. A front edge 19 of the side wall 8 can have a corresponding shape. On the one hand, such an angled edge region 18 enables the side wall 7 to be stiffened at the front. In addition, such an integrated uneven edge structure also enables further additional components to be connected to this base body 13 at this local front point of the side wall 7. The same then also applies to the connection of additional parts to the front edge of the side wall 8. In particular, such an angled edge region 18 extends over the entire height of the front edge 17.

In one exemplary embodiment, it can be provided that a coupling receptacle 20 is integrated in this angled edge region 18, in particular in the front L-leg 18b, and is therefore formed in one piece with it. Such a coupling receptacle 20 is designed for coupling with another additional component of the household refrigeration appliance 1. The coupling receptacle 20 can have a survey and/or a breakthrough. In this way, for example, a plug connection and/or a snap connection can be created between the front edge region 18 and this further additional component.

In one exemplary embodiment, the base body 13 has an angled edge region 24 and/or 25 and/or 26 on an upper edge 21 of the side wall 7 and/or on an upper edge 22 of the side wall 8 and/or on an upper edge 23 of the rear wall 9 . This makes it possible to create an individually integrated coupling structure for coupling to the separate roof wall 10.

The same can also be done on a lower edge 27 of the side wall 7 and/or on a lower edge 28 ( 2 ) of the side wall 8 and / or on a lower edge 29 of the rear wall 9 can be provided integrated. Angled edge regions can also be integrated there.

In one exemplary embodiment, this one-piece base body 13 made of metal can be manufactured by first providing a plate-like blank made of metal. This can be a flat plate, especially made of sheet steel. In one exemplary embodiment, at least one coupling elevation 14 and/or at least one deformed edge region 18 and/or 19 and/or a correspondingly angled edge region 24, 25, 26 is first attached to the upper edge 21 and/or 22 and/or 23 and/or a angled edge region is generated on the lower edge 27 and/or 28 and/or 29. This can be done by appropriate forming, in particular bending and/or drawing and/or punching. Preferably, in one embodiment, a slot continuous through the metal material is first created in the flat, plate-like blank at a local location at which a coupling elevation 14 is to be created. Subsequently, a bulge of the coupling elevation 14 is then formed at this local location by shaping at least a surface area of the blank that adjoins this slot out of the plane of the blank by reshaping. For example, in this context, an embossing die adjacent to the slot can act on the material of the plate-like blank, so that the partial area 15 is created by embossing. In particular, as already mentioned above, a corresponding U-shaped bulge is generated as a corresponding subarea 15. In this regard, the free U-legs are then formed as front and rear legs when viewed in the depth direction and the bottom leg of this U-shape is formed by a roof area of this sub-element 15.

In one exemplary embodiment, the formation of the U-shape of the base body 13 is then carried out subsequently to produce the coupling elevations 14 and/or the angled edge regions. For this purpose, bending edges 30 and 31 are created, so that this U-shape with the side walls 7 and 8 and the rear wall 9 arranged at an angle to them is then formed from this plate-shaped blank.

In addition or instead of this, for example, coupling receptacles 32 can also be integrated in the angled edge region on the upper edge 21. Here too, one or more such coupling receptacles 32 can be designed to be integrated. These can be designed according to an exemplary coupling receptacle 20. The exemplary embodiments explained for the edge region 18 and/or the exemplary embodiments explained for the upper edge 21 can also be provided for the front edge region 19. Accordingly, the configurations of the upper edge 21, in particular with a coupling receptacle 32, can be provided for the upper edges 22 and 23. The same applies to the lower edges 27, 28 and 29.

In one embodiment, an inside 9a of the rear wall 9 and/or an inside 7a of the side wall 7 and/or an inside 8a of the side wall 8 can be structured and/or provided with an additional layer of color. Structuring can be done, for example, by etching or laser processing. A color layer can be realized, for example, by coating or by applying a film or the like. This means that an individual functionality can be formed on the inside facing the receiving space 6. This can be provided with a view to improved shock protection and/or force protection and/or with a view to improved corrosion resistance and/or with a view to an individual optical design.

In 4 a partial area of the household refrigerator 1 is shown in an exemplary embodiment in a perspective view. The side wall 8 is shown here as an example. This shows an exemplary embodiment of a coupling survey 14. This has a breakthrough 16. It also has a section 15. The breakthrough 16 is formed like a slot here. The side wall 8 has a first web 33 here. This first web 33 borders on the slot-like opening 16. The first web 33 is oriented away from the side wall 8 and facing away from the receiving space 6. It is therefore oriented protruding into the gap 5. In the exemplary embodiment, the side wall 8 has a second web 34 that is different from the first web 33. This second web 34 is arranged adjacent to the slot-like opening 16. The second web 34 is oriented away from the side wall 8 and facing away from the receiving space 6. These two webs 33 and 34 are arranged at a distance from one another when viewed in the height direction. They are oriented parallel to each other. In the exemplary embodiment they are implemented as plate strips. In particular, they are formed in one piece with the side wall 8. They can, for example, be bent out of the plane of the side wall 8 by forming, in particular bending. In particular, they can also be produced by punching or embossing.

These two webs 33, 34 form the partial area 15. These two webs 33 and 34 are oriented parallel. In particular, they each extend over the entire length of the slot-like opening 16. The length of the opening 16 is measured here in the depth direction (z direction). In one exemplary embodiment, these webs 33 and 34 form an extension of the opening 16 facing away from the receiving space 6. The opening 16 in the side wall 8 is thus extended outwards like a shaft.

In the exemplary embodiment, a carrier part 35 is also shown. This is to be understood as an example in terms of shape and geometry. The carrier part 35 is a component separate from the side wall 8. In one exemplary embodiment, the carrier part 35 can be made in one piece, in particular made of plastic. It can be, for example, an injection molded component.

The carrier part 35 is intended so that additional components or additional components, which are separate from the carrier part 35, can be arranged on it on the receiving space side. For example, such an additional component can be a plate 36, as shown in 5 is shown in some areas. Such a plate 36 can be, for example, a partition or a shelf.

In one exemplary embodiment, the carrier part 35 is designed as an elongated component. It can be shaped like a bar. The longitudinal axis of the carrier part 35 is in particular parallel to the longitudinal axis of the opening 16. In 4 It can be seen that in one exemplary embodiment, the carrier part 35 is arranged to protrude into the opening 16 over its entire length in a direction perpendicular to the longitudinal axis.

The carrier part 35 thus extends into the breakthrough 16 in the width direction (x-direction), which is a spatial direction perpendicular to the longitudinal axis of the carrier part 35 and to the longitudinal axis of the opening 16.

The carrier part 35 has a first boundary wall 37 in the exemplary embodiment. In the exemplary embodiment, this is an upper boundary wall or a roof wall. In one exemplary embodiment, the carrier part 35 has a second boundary wall 38. This can be a lower or a floor wall. In the exemplary embodiment, the carrier part 35 is hollow at least in some areas. A hollow area 39 is delimited here at the top and bottom by the boundary walls 37 and 38.

At least one first locking step 40 is formed on an outside 37a of the boundary wall 37 facing away from the hollow region 39. Several such locking stairs 40 can also be provided, as shown for example in 4 is shown.

In particular, in one exemplary embodiment, an at least further or second snapping staircase 41 ( 5 ) educated. Here too, several such second snapping steps 41 can be formed along the longitudinal axis. Each of these locking steps 40 and/or each of these locking steps 41 each has at least two locking steps 40a, 40b and/or 41a, 41b, as shown in 5 is shown on. The carrier part 35 protruding through the opening 16 can thus be snapped in different positions, in particular with the different snap steps 40a, 40b, 41a, 41b. In particular, the carrier part 35 is thus snapped to the web 33 and/or 34.

In general, it is provided that the carrier part 35 is held on the side wall 8 only with snap connections.

In one exemplary embodiment, the web 33 has a free edge 33a facing away from the receiving space 6. Accordingly, in one exemplary embodiment, the web 34 has a free edge 34a facing away from the receiving space 6. In particular, in the snapped state, the snapping steps 40 and/or 41 rest directly on this free edge 33a and/or 34a, as shown in FIG 4 and 5 can be recognized.

Furthermore, in 4 and 5 It can also be seen that in one exemplary embodiment one or more stiffening webs 42 are formed in the hollow region 39. As a result, the hollow area 39 is reinforced. The stiffening webs 42 preferably extend over the entire clear width between the boundary walls 37 and 38.

In one embodiment it can be provided that a stiffening web 42, as shown in 5 is shown, is arranged in the direction of the longitudinal axis of the support part 35 at the longitudinal position at which a first snapping staircase 40 and a second snapping staircase 41 are also arranged. As a result, stiffening is achieved locally in the exemplary embodiment precisely at the points where two snapping stairs 40 and 41 are located opposite one another.

In one exemplary embodiment, the carrier part 35 has a first contact flange 43. In a further exemplary embodiment, a second contact flange 44 can be provided in addition to or instead of this. This contact flange 43 is intended to rest against an inside 8a of the side wall 8. This can be in a wall area 45 of the side wall 8, which here borders the opening 16 at the top. Accordingly, it can be provided that the second contact flange 16 rests on the inside 8a of the side wall 8, in particular in a lower wall region 46, which adjoins the opening 16 at the bottom.

In particular, the carrier part 35 has a coupling section 47 which projects into the receiving space 6 and which is designed and provided for coupling with a separate additional component 36. In particular, the carrier part 35 is arranged such that the first web 33 is arranged clamped between at least one snap-in staircase 40 and at least the first contact flange 43. In particular, in addition to or instead of this, it can be provided that the second web 34 is arranged clamped between at least one locking step 41 and at least the second contact flange 44.
