Description

[0001] The invention relates to a holding device for holding a screen on a seating system for a motor vehicle according to the preamble of claim 1.

[0002] DE 10 2023 002 204 A1 discloses a screen holder for arranging a screen on the back of a seat backrest, comprising a support rotatable about a first axis of rotation relative to a seat holder, wherein the support is rotatably connected at its opposite end to the seat holder to a screen mount about a second axis of rotation.

[0003] From EP 4 371 823 A2 a rearview device for a vehicle is known, wherein the rearview device comprises at least one arm which is rotatably mounted about at least one pivot point for a first rotation by means of the first fastening device about at least one first axis of rotation having at least one vertical component.

[0004] From DE10 2017 213 921 A1 a screen arrangement for a motor vehicle with a screen is known, wherein the screen is arranged in a vehicle interior and is rotatable about an axis of rotation which is essentially perpendicular to the screen.

[0005] From DE 10 2013 222 449 A1 a device for holding flat, approximately rectangular devices such as tablet computers or mobile phones in the interior of a motor vehicle is known.

[0006] The object of the present invention is to create a holding device for holding a screen on a seat system for a motor vehicle, so that the manufacturing effort of the motor vehicle can be kept particularly low.

[0007] This problem is solved according to the invention by a holding device for holding a screen on a seat system for a motor vehicle with the features of claim 1. Advantageous embodiments with expedient further developments of the invention are specified in the remaining claims.

[0008] The invention relates to a holding device for mounting a screen on a seat assembly for a motor vehicle, or the motor vehicle itself. The motor vehicle is, for example, a passenger car. Preferably, the motor vehicle, particularly in its fully manufactured state, includes the holding device. In particular, the motor vehicle includes the screen and the seat assembly.

[0009] The term "seating system" can refer in particular to a vehicle seat, which is to be arranged or is to be arranged in the interior of a motor vehicle. Accordingly, the seating system is specifically designed for seating at least one vehicle occupant. The interior, which can also be referred to as the vehicle interior, can refer in particular to a passenger compartment or passenger cell.

[0010] The holding device has at least one first holding element, which can be arranged, in particular directly, on the seat assembly and which can be referred to as an interface bracket. The first holding element has at least one first attachment area by which the first holding element can be attached, preferably pivotally, to the seat assembly, for example, to at least one component of the seat assembly, particularly at least indirectly or directly, on a rear side of the seat assembly, especially when the holding device is installed in the vehicle, particularly in the interior, and especially on the rear side of the vehicle, in the longitudinal direction of the vehicle. In other words, the first holding element is held, or is held, on the rear side of the seat assembly.Preferably, the first retaining element extends at least partially, and in particular predominantly or completely, further rearward in the longitudinal direction of the vehicle than the seating system, and in particular the component. Thus, for example, the first retaining element is arranged behind the seating system, and in particular behind the component, in the longitudinal direction of the vehicle. The first mounting area includes or forms, for example, at least one pivot point, in particular designated as the pivot point, at which the first retaining element can be rotatably attached to the seating system, and in particular to the component, relative to the seating system, and in particular to the component. The rotatability is, for example, rotation about several spatial axes.

[0011] Furthermore, the holding device comprises at least one second holding element, which is separate from the first holding element and can be connected to or attached to the first holding element via at least one fastening device, for example, at least indirectly or directly. In other words, the holding elements can be attached to or fastened to one another via or by means of the fastening device. In particular, the holding device comprises the fastening device. For example, the fastening device is formed by the first and / or the second holding element. Thus, for example, the first and / or second holding element comprises the fastening device. The second holding element has at least one second fastening area via which the screen can be attached or fastened to the second holding element, for example, directly.In other words, the second mounting element can be connected or attached to the screen via the second mounting area, for example, in a way that prevents rotation. Because the screen can be attached or fastened to the second mounting element, and in particular because the first mounting element can be attached or fastened to the back of the seat, the screen can be attached or fastened to the back of the seat, specifically to the component, via the mounting device and the mounting elements, that is, specifically via the mounting areas. In other words, the screen can be held or fastened to the seat, for example, to the component of the seat, by means of the mounting device and the mounting elements, specifically via the mounting areas.

[0012] To minimize the manufacturing effort required to produce the motor vehicle, the invention states that the first mounting area, particularly in the installed position of the mounting device in the motor vehicle, especially in the interior, is arranged off-center on the first mounting element, for example, on a base body of the first mounting element, in the transverse direction of the vehicle. In other words, the first mounting area and the first mounting element, especially the base body of the first mounting element, are arranged offset or displaced relative to each other with respect to their central axes. This means that the first mounting area and the mounting element, especially the base body, are arranged axially offset from each other in the transverse direction of the vehicle, such that, for example, a central axis of the first mounting area is spaced apart from a central axis of the mounting element, especially the base body, in the transverse direction of the vehicle.The respective central axis preferably extends perpendicularly to the first mounting area or to the first retaining element, in particular to the base body. Furthermore, the respective central axis preferably extends, at least substantially, in the longitudinal direction of the vehicle. The respective central axis is thus preferably a central axis extending in the longitudinal direction of the vehicle and passing through the first mounting area or through the first retaining element, in particular the base body. In particular, the respective central axis is a central axis of the first mounting area or the first retaining element, in particular the base body, with respect to the transverse direction of the vehicle, and in particular with respect to a transverse direction of the first mounting area or the first retaining element, in particular the base body.

[0013] The invention is based in particular on the following findings and considerations: With particularly large screens or displays, for example, there is a challenge regarding the distance, especially in the transverse direction of the vehicle, to the interior, particularly to a vehicle occupant, and to the deployment area of ​​a head airbag, for example, in both vertical and horizontal positions. To maintain this distance, the horizontally positioned screen must, for example, be shifted transversely towards the center of the vehicle. This shift creates, for example, a pivot point that lies outside a line of symmetry of the screen in the transverse direction. Maintaining the distance between the screen and the head airbag can therefore be challenging.To ensure a correct camera perspective, a camera mounted across the screen must be positioned centrally, for example, at the center of one of the screen's top edges, while the screen is set to its horizontal position. Determining the camera's position can therefore be challenging. The aforementioned requirements regarding the distance to the head airbag and the camera's position can necessitate the use of two different screens, one on the left and one on the right side of the vehicle, particularly in terms of their construction. This can also lead to the need for two different mounting mechanisms for attaching the screens to the respective seats (e.g., left and right), two different sets of covers (e.g., left and right), and / or double the costs for development, tooling, and validation.

[0014] The aforementioned problems can be overcome by means of the mounting device according to the invention. Because the first mounting area of ​​the mounting device according to the invention is arranged centrally on the outside of the first mounting element in the transverse direction of the vehicle, the screen can be positioned offset relative to the first mounting area in the transverse direction of the vehicle on the seat assembly, in particular offset inwards in the transverse direction of the vehicle, thus ensuring, for example, that the distance between the head airbag and the screen is maintained. At the same time, the camera can be or remain centrally positioned on the screen in the transverse direction of the vehicle, allowing the identical screen to be used on the left and right sides of the vehicle in the transverse direction, i.e., for example, on a left-hand seat assembly and on a right-hand seat assembly spaced further apart from the left-hand seat assembly in the transverse direction of the vehicle.Furthermore, the screens can be attached to the respective seating system using an identical mounting device according to the invention. This avoids duplicate effort, and in particular, duplicate costs, by using the mounting device according to the invention, which allows for the required distance between the pivot point and the symmetrical screen. For example, a unit price reduction can be achieved by doubling the volume of the identical, especially symmetrical, screen and the identical mounting device, particularly an identical swivel mechanism, especially for arrangement in the rear area of ​​the interior in the transverse direction of the vehicle, on the left and right.For example, by using the same cover for the left and right arrangement, reducing development costs by 50%, reducing validation costs by 50%, reducing tooling costs by 50%, and / or enabling particularly fast assembly with a single screw directly in the vehicle.

[0015] Further advantages, features, or details of the invention will become apparent from the following description of a preferred embodiment and from the drawings. The features and feature combinations mentioned above in the description, as well as the features or feature combinations mentioned below in the figure description and / or shown in the figures alone, can be used not only in the combinations specified, but also in other combinations or individually, without departing from the scope of the invention.

[0016] This shows: Fig. 1 a schematic perspective view of a holding device according to the invention; Fig. 2 a schematic and perspective exploded view of a holding device according to the invention; Fig. 3 a schematic and perspective exploded view of a holding device according to the invention, in which a second holding element is arranged on a screen; Fig. 4 a schematic representation of the interior of a motor vehicle to illustrate a conventional holding device; and Fig. 5 a schematic representation of two holding devices according to the invention arranged on a respective screen.

[0017] In the figures, identical or functionally equivalent elements are provided with the same reference symbols.

[0018] Fig. Figure 1 shows a schematic perspective view of a holding device 10 for holding a screen 12 on a seat 14 for a motor vehicle. Fig. Figure 2 shows the holding device 10 in a schematic and perspective exploded view. The screen is shown in Fig. 2. Fig. Figure 3 illustrates the holding device 10, which is also shown in a schematic and perspective exploded view.

[0019] The holding device 10 has a first holding element 16 which is to be arranged or is arranged on the seat assembly 14. The first holding element 16 is thus designed, in particular, as a holding element on the seat assembly side. The first holding element 16 has at least one first mounting area 18, via which the first holding element can be attached or is attached to the seat assembly 14, for example, to a component 22 of the seat assembly 14, on a rearward side 20 of the seat assembly 14 that faces the longitudinal direction of the vehicle, preferably pivotally. The component 22 is designed, for example, as a headrest or as a backrest of the seat assembly 14. The pivotal attachment requires, for example, that at least one pivot point 24 is provided, at which the first holding element 16, which is to be attached or is attached to the seat assembly 14 via the first mounting area 18, can be rotated relative to the seat assembly 14, for example, about several spatial axes.

[0020] The holding device 10 further comprises a second holding element 26, which is formed separately from the first holding element 16. The second holding element 26 can be connected to the first holding element 16, in particular directly, via at least one fastening device 28. The second holding element 26 has at least a second fastening area 30, which is spaced apart from the first fastening area 18, for example, in the longitudinal direction of the vehicle. The second fastening area 30 is not visible in the figures, as it is located in the Fig. 1, Fig. 2 and Fig. 3 shown in the illustration on a respective, non-visible reverse side of the second retaining element 26. The second fastening area 30 is therefore in Fig. 2 and Fig. Figure 3 is illustrated only by means of an arrow, which is intended to indicate this non-visible rear side. The screen 12 can be attached, in particular directly, to the second mounting element 26 via the second mounting area 30, whereby the screen 12 can be attached, or is attached, to the seat 14, in particular to the component 22, via the mounting device 10 and the mounting elements 16, 26 on the rear 20 of the seat 14. The second mounting element 26 is thus designed, in particular, as a screen-side mounting element. The second mounting element 26 can be part of a housing element of the screen 12. The housing element can also be referred to as the screen housing.

[0021] To minimize the manufacturing effort of the motor vehicle, the first mounting area 18 is arranged off-center in the transverse direction 34 of the vehicle on the first retaining element 16, in particular on the base body 35 of the first retaining element 16. Thus, for example, a first distance 36, which extends in the transverse direction 34 between an outer end 38 of the first mounting area 18 and an outer end 40 of the first retaining element 16, in particular the base body 35, is different from a second distance 42, which extends in the transverse direction 34 between an inner end 44 of the mounting area 18 and an inner end 46 of the first retaining element 16, in particular the base body 35. For example, the first distance 36 is smaller than the second distance 42.In particular, the pivot point 24 is arranged off-center on the first retaining element 16.

[0022] Preferably, the first mounting area 18, in particular the pivot point 24, and the second retaining element 26 are arranged axially offset from each other in the transverse direction 34 of the vehicle. In other words, the first mounting area 18, in particular the pivot point 24, is arranged off-center with respect to the second retaining element 26 in the transverse direction 34 of the vehicle.

[0023] Preferably, the first mounting area 18, in particular the pivot point 24, and the mounting device 28 are arranged axially offset from each other in the transverse direction 34 of the vehicle. In other words, the first mounting area 18, in particular the pivot point 24, is arranged off-center with respect to the mounting device 28 in the transverse direction 34 of the vehicle.

[0024] Preferably, the screen 12, which can be attached to or is attached to the second mounting area 30, is arranged axially offset in the transverse direction 34 of the vehicle relative to the first mounting area 18, in particular the pivot point 24. In other words, the screen 12, which can be attached to or is attached to the second mounting area 30, is arranged decentrally in the transverse direction 34 with respect to the first mounting area 18, in particular the pivot point 24.

[0025] Preferably, the screen 12, which can be attached to or is attached to the second mounting area 30, is arranged centrally in the transverse direction 34 of the vehicle with respect to the second mounting element 26. In other words, the second mounting element 26 is arranged centrally with respect to the screen 12 in the transverse direction of the vehicle or in the transverse direction of the screen 12.

[0026] The advantages of the holding device 10 are particularly evident in comparison to Fig. Figure 4 clearly shows a conventional arrangement of two conventional screens 12a, 12b in the interior 48 of a motor vehicle. The first screen 12a is attached to a first seat assembly 14 by means of a first conventional mounting device 10a. The second conventional screen 12b is attached to a second seat assembly 50, which is spaced from the first seat assembly 14 in the transverse direction 34 of the vehicle, by means of a second conventional mounting device 10b, which is distinct from the first conventional mounting device 10a. In the event of an accident involving the motor vehicle, a respective side airbag 51, which is designed in particular as a head airbag, is displaced inwards in the transverse direction 34 of the vehicle when it deploys.Therefore, for example, a minimum distance is provided between the respective screen 12a, 12b and the side airbag 51 or a lateral outer boundary of the interior 48 in the transverse direction 34 of the vehicle. This results in the respective conventional screen 12a, 12b being offset inwards in the transverse direction 34 of the vehicle relative to the respective seat assembly 14, 50. A respective camera 52 of the respective conventional screen 12a, 12b is arranged at the upper end of the respective conventional screen 12a, 12b in the transverse direction 34 of the vehicle, and centrally on the respective conventional screen 12a, 12b. This, in combination with the aforementioned respective offset of the respective conventional screen 12a, 12b relative to the respective seat assembly 14, 50, results in the following: Fig. In the arrangement shown for the conventional screens 12a, 12b, no identical screens can be used, which has a negative impact on the manufacturing costs of the motor vehicle.

[0027] This can be avoided by means of the mounting device 10, whereby a screen 12 can be attached to each of the respective seat units 14, 50 by means of the mounting device 10 or one of the mounting devices 10. This means that a first screen 12 can be attached to the first seat unit 14 with a first mounting device 10, and a second screen 12, which is identical in construction to the first screen 12, can be attached to the second seat unit 50 by means of the second mounting device 10. A special interface mount in the form of the mounting device 10 can thus be used, which can maintain the described respective distance to the respective side airbag 51, which is, for example, the respective distance between the side airbag 51 and the pivot point 24, from the respective screen 12.In particular, the screen 12 can be designed symmetrically, which means that identical screens can be used for the two screens 12.

[0028] This is in Fig. Figure 5 illustrates the two holding devices 10 and the two screens 12 in the interior space 48. Fig. Figure 5 illustrates possible mounting combinations. Accordingly, the respective symmetrical screen 12 can, for example, be arranged on the left or right side of the interior space 48, particularly in a rear area of ​​the interior space 48, in the transverse direction of the vehicle.

[0029] In particular, the camera 52 of the screen 12 is arranged in the middle of the screen 12 in the transverse direction 34 of the vehicle or in the transverse direction of the screen 12, especially at its upper end in the vertical direction of the vehicle or in the vertical direction of the screen 12.

[0030] As in Fig.As illustrated in Figure 5, a median plane 54 of the first mounting area 18 is preferably spaced apart from a median plane 56 of the screen 12. The median plane 54 can be referred to as the first median plane 54. The median plane 56 can be referred to as the second median plane 56. In particular, the first median plane 54 is arranged further outwards in the transverse direction 34 of the vehicle than the second median plane 56. In this case, the first median plane 54 is a median plane 54 of the first mounting area 18 with respect to the transverse direction 34 of the vehicle, or with respect to a transverse direction of the first mounting area 18. Preferably, the first median plane 54 passes through the pivot point 24. Preferably, the first median plane 54 extends perpendicular to the first mounting area 18. In particular, the first median plane 54 extends in the vertical direction and in the longitudinal direction of the vehicle.Thus, the first median plane 54 extends, for example, perpendicular to the vehicle's transverse direction 34. The second median plane 56 is, in this case, a median plane 56 of the screen 12 with respect to the vehicle's transverse direction 34, or with respect to the transverse direction of the screen 12. In particular, the second median plane 56 intersects the camera 52. The second median plane 56 extends, for example, in the vehicle's vertical and longitudinal directions. Accordingly, the second median plane 56 runs, for example, perpendicular to the vehicle's transverse direction 34. The median planes 54 and 56 preferably extend parallel to each other.

[0031] For example, the fastening device 28 has at least one pin 58, preferably several pins 58, for example four pins 58, for connecting the retaining elements 16, 26 to one another. The respective pin 58 is, for example, arranged on the second retaining element 26, and in particular attached to it. Furthermore, the fastening device 28 has, for example, a receiving opening 60 in which the respective pin 58 for connecting the retaining elements 16, 26 is received, in particular in a form-fitting manner. The respective receiving opening 60 is, for example, designed as a keyhole. This means that the respective receiving opening 60 has a keyhole-shaped geometry. In the present case, the respective receiving opening 60 is arranged on the first retaining element 16. The retaining device 10, in particular the first retaining element 16, can thus be equipped with slots and / or keyholes.

[0032] The screen 12, or the second retaining element 26, can therefore be provided with pins 58. Each pin 58 can be understood to be, in particular, a pin. Each pin 58 has, for example, at least one notch.

[0033] For example, the retaining elements 16, 26 can be screwed together, particularly directly, or are screwed together. Thus, for example, the fastening device 28 has at least one screw element 66. Furthermore, the fastening device 28 has, for example, at least one screw-in area 68 into which the screw element 66 can be screwed in, or is screwed in, for screwing the retaining elements 16, 26 together. For example, the screw element 66 is arranged, and in particular held, on the first retaining element 16. For example, the screw-in area 68 is arranged, or formed, on the second retaining element 26.

[0034] For example, the following assembly sequence is possible. First, for example, the second retaining element 26 is attached to the screen 12, in particular via the second mounting area 30. For example, and in particular subsequently, the screen 12 can be positioned in the receiving openings 60 of the first retaining element 16 using the pins 58. For example, and in particular subsequently, the screen is slid to the side to allow the pins 58 to engage in the receiving openings. For example, and in particular subsequently, the screw element 66 is tightened. The screw element 66, which is designed, for example, as a screw, is preferably already pre-assembled on the holding device 10, in particular on the first retaining element 16.

[0035] Overall, it is evident that a modular mounting interface for displays can be created in the form of the holding device 10.
