Description

The proposed solution relates to an adjustable table assembly for a vehicle, which is set up to provide a width-adjustable flat surface for placing objects.

Table assemblies with usable areas that can be adjusted in width are known in principle from the field of furniture construction. An adaptation of the usable area is mainly realized by fold-out or insertable tabletops. The table tops that can be folded out or inserted take up a relatively large volume even when they are not folded out or not inserted. Such table assemblies are therefore regularly heavy and bulky.

The object is to improve a table assembly with regard to the disadvantages of the prior art.

This problem is solved by a table assembly with the features of claim 1.

• - ein Basiselement,
• - zwei mit dem Basiselement verbundene Strukturelemente von denen mindestens ein Strukturelement relativ zu dem Basiselement entlang einer Ausfahrrichtung zwischen einer eingefahrenen Position und mindestens einer ausgefahrenen Position verstellbar ist, und
• - eine mit beiden Strukturelementen verbundenes aufrollbares Tischelement, das an mindestens einem der Strukturelemente aufrollbar gelagert ist, wobei in der mindestens einen ausgefahrenen Position des mindestens einen verstellbaren Strukturelementes ein abgerollter Abschnitt des Tischelementes eine ebene Benutzungsfläche bereitstellt.

Accordingly, a proposed adjustable table assembly for a vehicle includes at least:

• - a base element,
• - Two structural elements connected to the base element, of which at least one structural element can be adjusted relative to the base element along an extension direction between a retracted position and at least one extended position, and
• - A rollable table element connected to both structural elements, which is mounted on at least one of the structural elements such that it can be rolled up, wherein in the at least one extended position of the at least one adjustable structural element, a rolled-down section of the table element provides a flat user surface.

As a result, the proposed table assembly can be adjusted between a compact position and an extended position. In the usage position, the proposed table assembly with the unrolled section of the table element can provide a usage surface that can be suitable in particular for a user to put down objects. In the compact position, the table assembly can reduce a volume occupied by the table assembly and, in particular, a floor space occupied by the table assembly. Thus, in the compact position, the table assembly can reduce the likelihood of being an obstacle to a moving person. Consequently, particularly in rooms of limited size, the table assembly can be selectively adjusted between the compact position and the use position to either reduce the occupied floor space or to provide a use area.

In a further embodiment of the proposed solution, an extension of the usage area along the extension direction can be adjusted by rolling the table element along a rolling direction. This allows the table assembly to be adapted to different usage situations.

Further, the adjustable table assembly may be adjustable between the compact position and a plurality of extended use positions. As a result, the proposed table assembly can be adapted to other usage situations in which different dimensions of the usage area are desired by a user. In particular, the proposed adjustable table assembly can be steplessly adjustable between the plurality of usage positions. This can further improve the convenience of use.

In a further embodiment of the proposed adjustable table assembly, the extension direction can run parallel to the unwinding direction. This can reduce a construction effort.

Alternatively or additionally, an adjustment of the at least one adjustable structural element along the extension direction can be coupled with a rolling of the table element. This can increase ease of use of the adjustable table assembly.

The proposed table assembly can be set up to transfer an adjustment force introduced into the at least one adjustable structural element to the table element in such a way that it is unrolled along the rolling direction. For example, the adjustable table assembly can have a coupling mechanism for this purpose, which transmits the adjustment force from the adjustable structural element to the table element. Accordingly, the at least one adjustable structural element and the table element can be operatively connected.

Analogously, it is also conceivable and possible for the adjustment of the at least one adjustable structural element to be coupled with the rolling up of the table element in the opposite direction to the extension direction.

In a further embodiment of the proposed solution, the use area can be rigid in relation to a force introduced along a force orthogonal to the use area. As a result, the suitability of the usable area for a user to put down objects can be improved. In particular, objects with a non-negligible intrinsic weight, such as cups, computers and the like, can also be placed on the user area without it becoming deformed. This can avoid a risk of the objects placed on the use area slipping.

In a further embodiment of the proposed solution, the table element can be designed with a link apron. This can improve bending stiffness related to a force applied orthogonal to the user surface.

The link apron can have a plurality of elements coupled to one another. The link apron can thus have an anisotropic flexural rigidity.

In particular, the link apron can be rolled up in one direction and rigid in at least one other direction.

In a further embodiment of the proposed solution, the link apron can have a plurality of pairs of slats pivotally connected to one another. As a result, the link apron can be rolled up or down about an axis of rotation parallel to the axis of longitudinal extent of the slats.

In a further embodiment of the proposed solution, the slats can be set up to block a displacement of the slats along a force that is introduced orthogonally to the surface of use in an unrolled state. This can further increase the flexural rigidity of the surface of use in relation to a force introduced orthogonally to the surface of use.

For example, each of the slats can be set up for releasable attachment to the respective adjacent slats. Due to the releasable setting, adjacent slats can form a rigid composite. This can improve a load capacity of the usage area.

Furthermore, by way of example, the slats can each have a coupling section and a coupling section for releasable fixing, wherein the coupling sections and the coupling sections of adjacent slats can be connected to one another.

The connection of the coupling sections and the coupling section of respectively adjacent slats can be detachable depending on an angle enclosed by the longitudinal axes of the slats. This can enable detachment or connection of adjacent slats depending on the angle enclosed between the adjacent slats.

In a further embodiment of the proposed solution, the coupling section of one of the slats can encompass an adjacent one of the slats in such a way that a pivoting path of the slat in a pivoting direction is restricted by the coupling section. For this purpose, the adjacent slat can have a coupling section which, when a pivoting end position is reached, bears against the coupling section of the slat and blocks further pivoting along the pivoting direction. In particular, the slat and the adjacent slat can define a flat surface in the pivot end position.

The coupling sections of the slats can be designed in such a way that in the region of the unrolled section the coupling sections of all slats each rest against a coupling section of an adjacent slat and block displacement of the slats in the unrolled section along a direction orthogonal to the usage surface.

In a further embodiment of the proposed solution, the at least one adjustable structural element for rolling up the table element has a table shaft that is prestressed with respect to at least one direction of rotation. This can simplify rolling up and/or unrolling of the table element.

The table shaft can have a torsion spring, for example. The torsion spring can be arranged on the table shaft such that when the table shaft rotates along the at least one direction of rotation, the torsion spring introduces a restoring force directed counter to the at least one direction of rotation into the table shaft. As a result, the table element can be rolled up essentially automatically after it has been unrolled. An active rotation of the table shaft can therefore only be necessary when rolling up or unrolling the display film.

By way of example, the table element can roll up by itself against the extension direction by adjusting the at least one structural element. It is also conceivable and possible for the table element to roll up by itself when the at least one structural element is adjusted along the projection direction.

The table shaft can be a substantially cylindrical or rod-shaped body that is rotatably mounted on the at least one adjustable structural element. The table element can be connected to the table shaft in a fixed or pivotable manner with one end section. The table element can thus be rolled up and unrolled on the table shaft by rotating the table shaft.

In a further embodiment of the proposed solution, the table shaft can be set up to rotate along the at least one pretensioned direction of rotation by adjusting the at least one adjustable structural element. This can simplify a coupling of the adjustment of the at least one adjustable structural element and the rolling of the table element.

The table element can each be connected to one of the structural elements with two opposite end sections. The table element can be connected to the at least one adjustable structural element via the table shaft.

In a further refinement of the proposed solution, the table assembly can have a display film which can be rolled up and is connected to the structural element, for displaying visual content. The display film can be mounted on at least one of the structural elements so that it can be rolled up. As a result, the table assembly can be set up to provide a display of different sizes.

In a further embodiment of the proposed solution, in the at least one extended position of the at least one adjustable structural element, an unrolled section of the display film can provide a viewing surface that is visible to a user. In particular, the viewing surface can be flat. This can increase viewing comfort. In particular, the viewing area can be arranged on the table assembly in such a way that a user standing or sitting on the table assembly can see content on the display film in the area of the viewing area.

By way of example, the display film can be set up to display content only in the area of the viewing area.

The display foil can provide the viewing surface both in the compact position of the proposed table assembly and in the extended position. An extension of the viewing area in the compact position can be smaller than an extension of the viewing area in the use position.

In an alternative configuration, the display film can provide the viewing surface exclusively in the usage position or the plurality of usage positions. This can reduce the likelihood of the display foil being damaged when the table assembly is in the compact position. This can increase the life of the table assembly. By way of example, the proposed table assembly can thus be optionally adjusted between the display-free, space-saving compact position and the usage position with the usage area and display.

In a further alternative embodiment, the proposed table assembly can be adjusted between a plurality of usage positions of different widths. In this case, the viewing surface can only be provided in some of the usage positions. The proposed table assembly can thus be adjusted between one of the usage positions with a small usage area without a display and one of the usage positions with a larger usage area including a display.

In a further embodiment of the proposed solution, an extension of the viewing area along the extension direction can be adjusted by unrolling the display film along a further unrolling direction. As a result, the viewing area of the display film can be adapted to different usage situations.

In a further embodiment of the proposed solution, the viewing area can lie flat on the usage area. This can stiffen the viewing area or the display. In particular, the viewing area can thus be rigid in relation to a force acting orthogonally to the usage area. This can increase the ease of use and the service life of the display film.

For example, the display film can rest against the table element on the side of the usable area.

Alternatively, the display film can rest against the table element on a side of the table element that is opposite the usage area. In this case, the table element can be made of a transparent material, at least in sections, in order to enable the user to view the viewing surface. This can protect the viewing surface from external influences.

Alternatively or additionally, the viewing surface can be arranged between a plurality of table elements. For example, the display film can be sandwiched between two table elements. Here, at least one of the table elements can be formed with a transparent material in order to enable viewing of the sandwiched display.

In a further embodiment of the proposed solution, the display film can be framed by at least two table elements on the sides such that in the at least one extended position of the at least one adjustable structural element the viewing area is framed on at least two sides by user areas. As a result, the table assembly can be used for a number of application situations.

In a further configuration of the proposed solution, the adjustment of the at least one adjustable structural element along the extension direction and an unrolling of the display film along the further unrolling direction can be coupled. As a result, the viewing area can be provided at the same time, in particular when the user area is provided.

The proposed table assembly can be set up to transfer an adjustment force introduced into the at least one adjustable structural element to the display film in such a way that it is unrolled along the further unwinding direction. For example, the at least one adjustable structural element and the display film can be operatively connected in order to transfer the adjusting force from the adjustable structural element to the display film.

Analogously, it is also conceivable and possible for the adjustment of the at least one adjustable structural element to be coupled with the rolling up of the display film in the opposite direction to the extension direction.

For example, the extension direction can run parallel to the further rolling direction. This can simplify pairing.

In a further embodiment of the proposed solution, the at least one adjustable structural element for rolling up the display film can have a display shaft that is pretensioned with respect to at least one direction of rotation. This can simplify the rolling up and/or unrolling of the display film.

The display shaft can have a torsion spring, for example. The torsion spring can be arranged on the display shaft such that when the display shaft rotates along the at least one direction of rotation, the torsion spring introduces a restoring force directed counter to the at least one direction of rotation into the display shaft. As a result, the display foil can be rolled up essentially automatically after it has been unrolled. An active rotation of the display shaft can therefore only be necessary when rolling up or unrolling the display film.

In a further embodiment of the proposed solution, the display shaft can be set up to rotate along the at least one prestressed direction of rotation by adjusting the at least one adjustable structural element. This can simplify a coupling of the adjustment of the at least one adjustable structural element with the unrolling of the display film.

In one configuration, the display film can be formed with a flexible OLED display. This can reduce a possible radius of curvature when the display is rolled up.

Alternatively or additionally, the display foil can be designed with a digitizer for indicative or capacitive spatially resolved detection of touches of the display by a user. Such a digitizer can be connected to a control unit. Furthermore, the control unit can also be connected to the display foil and set up to cause an interaction of the content reproduced on the display foil in response to a detection of a touch and depending on a location of the touch on the digitizer.

In a further embodiment of the proposed assembly, the table assembly can have a drive for externally operated adjustment of the at least one adjustable structural element. This can increase the convenience of use.

The drive can in particular be designed with an electronically controllable motor coupled to the control unit. The motor can be set up to introduce the adjusting force into the at least one adjustable structural element in response to receiving a control signal from the control unit. The adjustment and the rolling can be controlled via the control unit. In particular, the control unit can initiate, stop and/or monitor the adjustment and/or the rolling. The control unit can have additional sensors for this purpose. Furthermore, the control unit can be set up via the additional sensors to detect an abort situation in which the adjustment and/or the rolling are blocked and/or stopped and/or reversed to protect people and/or objects must. In this case, the control unit can be set up to block and/or stop and/or reverse the adjustment and/or the rolling accordingly in response to the detection of the termination situation.

In a further embodiment of the proposed solution, the drive can be designed with at least one link chain, one end section of which is connected to the base element. As a result, a maximum possible adjustment path of the at least one adjustable structural element can be increased in the direction of the extension direction.

The at least one link chain can have a plurality of chain links which can be displaced relative to one another in a non-extended state, so that a non-extended section of the link chain is flexible. In an extended state, the chain links can lock against one another such that an extended portion of the at least one link chain is rigid. As a result, the usable area can be further reinforced.

Another end section of the at least one link chain can be arranged in an extendable manner on the at least one adjustable structural element. Thus, by extending the at least one link chain relative to the at least one adjustable structural element, the at least one structural element can be adjustable relative to the base element. By extending the at least one link chain, the adjustment force directed along the extension direction can be introduced into the at least one adjustable structural element. The at least one adjustable structural element can thus be adjustable by moving the at least one link chain along the extension direction between the retracted position and the at least one extended position.

By retracting the at least one link chain, the at least one adjustable structural element can be adjustable between the at least one extended position and the retracted position.

In an alternative embodiment, the link chain can be attached to the at least one adjustable structural element. By extending the link chain relative to the base element, the at least one structural element can be adjustable relative to the base element.

In a further embodiment of the proposed solution, the table assembly can have an unlocking mechanism for manual adjustment of the at least one adjustable structural element. This can also allow the table assembly to be adjusted in the event of a failed drive.

For example, the drive can be unlocked from the link chain. Accordingly, an operative connection between the drive and the at least one link chain can be detachable.

In one embodiment of the proposed solution, the drive can have a drive pinion, which is arranged on an output shaft of the motor and introduces the adjustment force into the at least one link chain. For unlocking, the drive pinion can be displaced relative to the link chain in such a way that the drive pinion and the at least one link chain are not engaged. In particular, the motor can be slidably mounted on the table assembly for this purpose.

In a further embodiment of the proposed solution, the drive can have at least one chain link and each of the at least one link chain can bear partially against a chain link with a guided section. As a result, the at least one link chain can be guided along an adjustment path predetermined by the at least one chain link.

In a further embodiment of the proposed solution, the at least one link chain can be flexible and thus deflectable in the section guided by the at least one chain link. This allows the at least one link chain to be deflected relative to the adjustable table assembly.

In a further embodiment of the proposed solution, the at least one link chain can be stiff in a free-running section that is not guided by the at least one chain link. This can increase the load capacity of the table assembly, in particular in the at least one extended position of the at least one adjustable structural element.

For example, the at least one chain link can be L-shaped. This can reduce a space requirement for the drive.

In a further embodiment of the proposed solution, a long section of the at least one L-shaped chain link can be arranged orthogonally to the extension direction on the at least one adjustable structural element. The long section of the at least one chain link can serve to accommodate a retracted section of the at least one link chain. Correspondingly, by aligning the long section of the min least one L-shaped chain link, the space required for the drive can be further reduced.

In a further embodiment of the proposed solution, a short section of the at least one L-shaped connecting link can be arranged parallel to the extension direction on the at least one adjustable structural element. As a result, the free-running section of the at least one link chain can be deflected in the direction of the extension direction. Consequently, by extending the at least one link chain out of the L-shaped chain link, the adjusting force directed in the direction of extension can be introduced into the at least one adjustable structural element.

In a further embodiment of the proposed solution, the table assembly can have at least one rail connected to the base element, via which the at least one adjustable structural element is connected to the base element. This can further increase a load capacity of the table assembly.

In a further embodiment of the proposed solution, the at least one rail can be telescopic along the extension direction. As a result, the installation space of the table assembly can be further reduced.

In a further embodiment of the proposed solution, the table assembly can have two structural elements that can be adjusted relative to the base element. This can increase a maximum extension of the usage area along the extension direction.

In principle, each of the two adjustable structural elements can correspond to one of the structural elements presented above. In particular, the two adjustable structural elements can correspond to two identical or two different embodiments.

In a further embodiment of the proposed solution, one of the two adjustable structural elements can be adjusted along the extension direction and the other of the two adjustable structural elements can be adjusted along a further extension direction running antiparallel to the extension direction.

In a further refinement of the proposed solution, each of the adjustable structural elements can be adjustable independently of one another between a retracted position and at least one extended position. This can improve suitability of the table assembly for a variety of application situations.

In a further embodiment of the proposed solution, the table element can be mounted on both adjustable structural elements in a manner that it can be rolled up via a table shaft in each case. In particular, the usable area can extend from one adjustable structural element to the other structural element. This can increase the size of an available user area.

In a further embodiment, both table shafts can be preloaded along at least one direction of rotation. This can allow the table element to roll up independently when the two structural elements are adjusted from one of the extended positions to one of the retracted positions or from the retracted position to one of the extended positions.

In a further refinement of the proposed solution, the display film can be mounted on both adjustable structural elements so that it can be rolled up via a display shaft in each case.

The proposed solution also relates to a vehicle with an interior space and an embodiment variant of a proposed adjustable table assembly arranged in the interior space. In this way, in particular, the usability of the interior can be improved.

In particular with regard to future, fully autonomous vehicles, the interior of the proposed vehicle can be flexibly redesigned. For example, the table assembly arranged in the interior can be adjustable for vehicle occupants to get in and/or out into the compact position, in which the at least one adjustable structural element is in the retracted position. This can increase the space available for movement in the interior. Furthermore, the table assembly can be adjusted into the at least one use position to provide a user area, for example for depositing objects or viewing multimedia content. By way of example, a table assembly with a usable area for a plurality of vehicle occupants located in the interior can hereby be provided in the interior.

The above statements on the embodiments and advantages of the table assembly also apply analogously to the proposed vehicle.

The attached figures illustrate exemplary possible embodiment variants of the proposed solution.

1A shows an adjustable table assembly 1 according to the proposed solution with a base element 2 and two structural elements 3, 3' connected to the base element 2, of which one of the structural elements 3` relative to the base element 2 along an extension direction D3 between an illustrated retracted position P1 and at least an extended position P2 is adjustable. Also connected to the two structural elements 3, 3' is a rollable table element 4 of the table assembly 1. The table element 4 is mounted on the adjustable structural element 3' so that it can be rolled up. In this case, the table element 4 is rolled up in the illustrated retracted position P1 of the at least one adjustable structural element 3 ′ and is fastened to the non-adjustable structural element 3 with an end section 613 .

1 B shows the table assembly 1 1A in an extended position P2. In this case, the adjustable structural element 3' is adjusted relative to the base element 2 along the extension direction D3. Due to the adjustment of the adjustable structural element 3' along the extension direction D3 and the attachment of the table element 4 to the non-adjustable structural element 3, the table element 4 is opposite to the illustration in 1A partially unrolled. The unrolled section extends between the two structural elements 3, 3' and provides a flat surface 41 for use. This user area 41 is particularly suitable for a user to put down objects. By adjusting the adjustable structural element 3' in the opposite direction to or along the extension direction D3, an extension of the usage area 41 in the rolling direction D4, D4' can be reduced or enlarged.

In 2 the roll-up table element 4 is shown in one embodiment as a link apron. The link apron includes a plurality of longitudinally extending slats 42 each pivoted to an adjacent slat 42 . The link apron shown is divided into a section rolled up around a table shaft 43 and an unrolled section that provides the surface 41 for use. The ability of the slats 42 to pivot about their pivot axes is restricted by the shape of the individual slats 42 in such a way that, starting from a planar arrangement of the slats 42 in the area of the usage area 41, each individual slat 42 can only be pivoted in one pivoting direction. Pivoting along the opposite pivoting direction, on the other hand, is blocked in the planar arrangement by pairs of coupling sections 421 and coupling sections 422 abutting one another. As a result, the usable area 41 provided by the unrolled section is rigid in relation to forces acting along a vertical.

3A shows two adjacent slats 42, 42' from the region of the unrolled section in cross section. Each of the slats 42, 42' has a transverse axis 423, 423`. In the area of the unrolled section or the area of use 41, the transverse axes 423, 423' of adjacent slats 42, 42' run parallel. The lamella 42 also has a connecting section 420 which is circular in cross-section and which is pivotally mounted in a corresponding circular recess in the adjacent lamella 42`. As a result, the slats 42, 42' are connected to one another such that they can pivot in relation to one another. The pivoting of the slats 42, 42' in the direction of the usage surface 41 is blocked by the coupling section 421 of each slat 42, 42' resting against a coupling section 422 of the respectively adjacent slat 42, 42'. In contrast, the pivoting of the slats 42, 42' along a direction pointing away from the use area 41 is not blocked.

In 3B is opposite 3A the adjacent slat 42' is pivoted towards each other along the direction away from the use surface 41. The transverse axes 423, 423' of adjacent slats 42, 42' accordingly do not run parallel but enclose a pivoting angle α.

4A shows part of a further embodiment of the proposed table assembly 1. Here, a beam-shaped base element 2 is arranged centrally, on which four rails 7 are arranged transversely to a longitudinal axis of extension of the base element 2 and on both sides beyond the base element 2. The rails 7 can be telescoped along an extension direction D7. The two adjustable structural elements 3 ′ are connected to the base element 2 in such a way that they can be adjusted relative to the base element 2 via the rails 7 . The one of the two structural elements 3' shown in the picture above can be adjusted along the extension direction D3 and the one shown in the picture below can be adjusted along a further extension direction D3'. The extension direction D3 and the further extension direction D3' run antiparallel to one another. Furthermore, the illustrated part of the table assembly 1 includes four link chains 61. Two of the four link chains 61 are each pivoted on one side of the base element 2 on the base element 2. FIG. The two link chains 61 pivotably linked on one side in each case serve to drive 6 one of the two structural elements 3 ′. For this purpose, the structural elements 3' each have two L-shaped chain links 65, each of the chain links 65 being arranged with a long section 651 orthogonally to the extension direction D3, D3' on the respective structural element 3'. Correspondingly, the short sections 652 of the four chain links 65 run parallel to the extension direction D7. in the in 4A In the retracted position P1 of the two structural elements 3' shown, the four link chains 61 each lie against one of the chain links 65. In particular, a large part of each of the four link chains 61 is thus accommodated in the long section 651 of one of the chain links 65 . By extending the link chains 61 from the chain links 65, adjustment forces can be introduced into the adjustable structural elements 3', starting from the retracted position P1 shown. The adjustable structural element 3' shown in the image above can be adjusted along the extension direction D3 and the other structural element 3' shown in the image below can be adjusted along the further extension direction D3'.

In 4B are compared to the representation in 4A the link chains 61 shown only incomplete. In particular, the in 4B illustrated plan view thereby four motors 62 for externally operated adjustment of the two structural elements 3 '. Each of the four motors 62 has a drive pinion 63 which is in engagement with one of the four link chains 61 in each case. Consequently, the link chain 61 can be adjusted by a motor through the drive 6 of the drive pinion 63 . Furthermore, the illustration in 4B two unlocking mechanisms 64. In each case one unlocking mechanism 64 is arranged on one of the adjustable structural elements 3' between the telescoping rails 7. Each of the unlocking mechanisms 64 is also connected to the two motors 62 which are set up to drive the two link chains 61 for driving 6 one of the two structural elements 3'.

5A shows a detailed representation of some drive components as well as the unlocking mechanism 64 of the in 4A adjustable structural element 3' shown above. The two motors 62 associated with the structural element 3 ′ are mounted on the rails 7 so that they can be displaced along the extension direction D7 of the rails 7 . Furthermore, both motors 62 are connected to a carriage 643 of the unlocking mechanism 64 which meshes with an external thread of a worm 642 of the unlocking mechanism 64 . Due to the rotation of the worm 642, the carriage 643 and the motors 62 can be displaced along the extension direction D7. By shifting the motors 62 along the off In the pulling direction D7, the drive pinions 63 of the two motors 62 can be selectively engaged with or disengaged from a respective link chain 61. If the drive pinions 63 are in engagement with the link chains 61 , the link chain 61 can be adjusted by a motor via the motors 62 . A manual adjustment, on the other hand, can be blocked by a resistance to rotation of the drive pinion 63 . If the drive pinions 63 are disengaged from the link chains 61 via the unlocking mechanism 64, the adjustable structural element 3' can consequently be adjusted manually along the extension direction D7. Furthermore, the unlocking mechanism 64 in the 5A illustrated embodiment has an electronically controllable motor 641 for electronic unlocking and locking or switching between manual and power-actuated adjustability.

5B shows the detail view 5A . In contrast to 5A is that in 5B illustrated adjustable structural element 3 'is displaced along the extension direction D3 relative to the base element 2. Correspondingly, the link chains 61 are each at least partially extended out of the section 611 guided by the chain links 65 in the direction of the base element 2 . Each of the two link chains 61 shown thus includes a free-running section 612 which extends counter to the extension direction D3 of the structural element 3' from the structural element 3' in the direction of the base element 2, which is not shown.

5C shows that in 4A above the base element 2 shown adjustable structural element 3 '. Centrally arranged is the worm 642 driven by the motor 641 of the unlocking mechanism 64, with which the motor 62 of the drive 6 can be adjusted along the extension direction D7 of the rails 7 in order to bring the drive pinion 63 into or out of engagement with the link chains 61.

6A shows a perspective view of the in 4A illustrated part of an embodiment of the proposed table assembly 1. As in 4A the four link chains 61 each lie against one of the chain links 65 . Thus, none of the link chains 61 has a free running section 612 . Consequently, both adjustable structural elements 3' are shown in their respective retracted position P1. The distance between each of the adjustable structural elements 3' relative to the base element 2 is minimal in each case.

Unlike the 6A show the 6B the part of the proposed table assembly 1 in the extended position P2. In this case, each of the four link chains 61 has a free-running section 612 which is not in contact with one of the chain links 65 . The free-running section 612 extends from the short section 652 of the L-shaped chain links 65 in the direction of the base element 2. By extending the link chains 61 out of the area of the chain links 65, the two adjustable structural elements 3' along the extension direction D3 or the further extension direction D3` relative to the base element 2 in the illustrated at least one extended position P2.

7 shows a perspective view of a further embodiment of the proposed table assembly 1. The table assembly 1 includes in the 4A until 6B shown part of the table assembly 1 and a table element 4 that can be rolled up with a table top 11 that cannot be rolled up and is arranged centrally between the two adjustable structural elements 3 ′. Adjoining the table top 11 on both sides and supported on each of the two structural elements 3 ′ so that they can be rolled up, the table top 11 is adjoined by a section of the table element 4 that is designed with lamellae 42 . In the illustrated extended position P2 of the two structural elements 3', the table element 4 with the unrolled section provides the usable surface 41, in particular for the user to set down objects.

The table element 4 can be rolled up around the table shafts 43 by adjusting the structural elements 3 ′ in the direction of the base element 2 . By adjusting the structural elements 3' along the extension direction D3 or the further extension direction D3', the table element 4 can be unrolled on each of the structural elements 3' along a respective unrolling direction D4, D4`. The rolling directions D4, D4' on both structural elements 3' run anti-parallel to the respective extension direction D3, D3' of the structural element 3'.

8th shows a further embodiment of the proposed table assembly 1, which, in contrast to that in 7 illustrated embodiment of the table assembly 1 has a rollable display film 5. The display film 5 is mounted on both adjustable structural elements 3' so that it can be rolled up via a display shaft 53. in the in 8th In the extended position P2 of the two adjustable structural elements 3' shown, the display film 5 with the unrolled section provides a viewing surface 51. On this, multimedia content can be displayed for a user to view.

The display foil 5 can be rolled up around the display shafts 53 by adjusting the structural elements 3 ′ in the direction of the base element 2 . By adjusting the structural elements 3' along the extension direction D3 or the further extension direction D3`, however, the display film 5 can be unrolled on each of the structural elements 3' along a respective further unrolling direction D5, D5'. The rolling directions D5, D5' on both structural elements 3' run anti-parallel to the respective extension direction D3, D3' of the structural element 3'.

9A and 9B each show a perspective view of a further embodiment of the proposed table assembly 1. The base element 2 in the embodiment shown is formed with a table base. Consequently, the table assembly 1 can be mounted on a floor, in particular a floor of a vehicle cabin, via the base element 2 . In 9A the two structural elements 3' are shown in a retracted position P1.

Contrast shows 9B the table assembly 1 with structural elements 3' adjusted relative to the base element 2 along the extension directions D3, D3'. A viewing surface 51 is arranged centrally between the two structural elements 3', lying flat on the usable surface. Multimedia content can be made available to users via the viewing area 51 of the display film 5 .

In variants of the proposed solution that deviate from the illustrated embodiments, the table element 4 that can be rolled up can be designed with a fabric tarpaulin and stiffening elements. The stiffening elements can be set up so that they are in a configuration that is rigid against bending when they are unrolled.

Furthermore, the drive 6 can in principle be designed with a pneumatic or a hydraulic drive 6 instead of a motor 62 . In this case, instead of using link chains 61, an adjusting force can also be realized in principle via cable drives, spindle drives or rack and pinion drives.

In a further alternative configuration, the motors 62 for introducing the adjusting force into the at least one adjustable structural element 3' can also be arranged on the base element 2 instead of on the at least one adjustable structural element 3'. In the exemplary embodiment variant in which the adjusting force is introduced into the at least one structural element 3' via link chains 61, the at least one link chain 61 can be attached to the at least one structural element 3'. Accordingly, the at least one link chain 61 can in principle also be guided at least partially via a chain link 65 arranged on the base element 2
