[0002] The invention relates to a seat device for a motor vehicle with at least one backrest according to the preamble of patent claim 1. Furthermore, the invention relates to an arrangement and a method.

[0003] Seating devices are already known from the prior art, which can be designed, for example, as a driver's seat or as a front passenger seat. A corresponding display device, for example in the form of a display or screen, can in turn be formed on a backrest of this seating device, so that persons located behind the seating device, in particular in a rear area of ​​the motor vehicle, can perceive corresponding entertainment information via the display device. Furthermore, display devices are known which can show corresponding content from a roof lining of the motor vehicle for the persons in the rear area. Both the display devices on the backrest and the display devices in the roof lining cannot be stowed away and can therefore disturb and impair the person in the rear area.

[0004] DE102004 009 309 A1 discloses a seat having a screen on the rear side of its backrest, which screen can be pivoted upwards by approximately 180° from a non-use position, in which the viewing surface of the screen faces the backrest in a protected manner, into a use position in which the viewing surface faces a viewer located behind the seat.

[0005] Furthermore, DE 202004 000292 U1 shows a flat screen (20) that slides completely into the seat back (10). A drive unit pushes it upwards through a slot (18) to its fully exposed position (20.4) or downwards to its lowest position (20.1).

[0006] DE 102020207 522 A1 presents a method for controlling a seat system. A physiological state of the seat occupant can be assessed based on at least two of heart rate, respiratory rate, and heart rate variability. A countermeasure can be implemented to change the seat occupant's physiological state, and / or data related to the heart rate, respiratory rate, and / or heart rate variability can be transmitted.

[0007] The object of the present invention is to provide a seating device, an arrangement and a method by means of which an improved and particularly convenient display of contents for a person can be realized.

[0008] This object is achieved by a seating device, an arrangement, and a method according to the independent patent claims. Advantageous embodiments are specified in the subclaims.

[0009] One aspect of the invention relates to a seat device for a motor vehicle having at least one backrest, wherein the backrest has at least one display device for a person sitting behind the seat device on a rear side of the backrest.

[0010] It is provided that the display device can be moved and / or pivoted from a non-use position by means of a sliding and / or pivoting device into a use position for viewing by the person.

[0011] In particular, the display device is movably mounted on the backrest and, in the non-use position, can be visually adapted to the backrest, thereby providing a visually appealing backrest in the non-use position. In particular, the display device does not impair the person's vision in the non-use position. In the use position, the display device has a corresponding display side, wherein, for example, content, in particular in the form of films or games, can be displayed on the display side. Furthermore, navigation information or the like can also be displayed on the display side.

[0012] In particular, the display device is thus embedded in the internal structure of the seating device, which is designed in particular as a driver's seat and / or as a front passenger seat. When not in use, the display device, or it is also possible for a plurality of display devices to be installed there, is invisible to the person and concealed by a rear seat cover, in particular in a vertical arrangement, in the respective front seat. The cover in particular reflects the interior or seat design of the seating device. During use, i.e. in the position of use, the display device is in turn folded out or extended so that the display device can be arranged in a sliding and rotating movement via the pivoting device.

[0013] This ensures that the display device, when not in use, does not impair or interrupt the person's clear view, which could, for example, disrupt the interior design. This also allows for improved visibility for rear passengers.

[0014] The seating device has an input device, and the input device is designed to pivot the display device from the non-use position to the use position or vice versa, depending on a respective input from the person. This allows the person in the rear area to pivot the display device depending on the person or user. This allows the person to conveniently pivot the display device from the non-use position to the use position or vice versa.

[0015] The input device is designed as a voice input device for receiving a voice command from the person. For example, based on a voice command, the display device can then be moved from the non-use position to the use position. This allows for extremely convenient pivoting of the display device.

[0016] According to an advantageous embodiment, a display side of the display device is concealed from the person in the non-use position. In particular, the display side can have a rear side, which in turn is shaped or designed in the same way as the rear side of the backrest, thereby creating a visually appealing backrest or rear side for the person.

[0017] Furthermore, it has proven advantageous if the pivoting device comprises a rail system for sliding and / or pivoting the display device. In particular, the rail system can provide a sliding or rotating movement, so that the display device can be reliably pivoted from the non-use position to the use position.

[0018] In a further advantageous embodiment, the position of use is adjusted depending on the inclination of the backrest. In particular, the inclination of the backrest can be detected, and the position of use can be adjusted accordingly depending on the respective inclination of the backrest, so that an improved view for the person can be achieved. Depending on how the inclination is adjusted, a correspondingly improved view of the display device can be realized for the person. In particular, the position change can be adjusted automatically depending on the inclination. This allows control of the inclination of the backrest.

[0019] According to a further advantageous embodiment, the pivoting device is designed for horizontal and / or vertical pivoting of the display device. In particular, both horizontal pivoting and vertical pivoting can thus be realized. Preferably, horizontal and vertical pivoting can be realized. For example, the position can then be adjusted accordingly depending on the person's wishes, and pivoting can be realized. Furthermore, it is also possible for the display device of an adjacent seat, for example, to be completely brought together with the display device of the adjacent seat, so that an essentially common screen or a common display device can be provided.

[0020] A further aspect of the invention relates to an arrangement for a motor vehicle with at least two seating devices according to the preceding aspect. In an advantageous embodiment of the arrangement, a first display device of a first seating device of the two seating devices and a second display device of a second seating device of the two seating devices are pivotable such that the first display device and the second display device form a common display surface. In particular, an electronic computing device can be provided for this purpose, which can detect the pivoting of the two display devices accordingly and, when the two display devices are brought together, recognizes that these two are brought together and, for example, then in turn determines and displays the corresponding display as a common display.In particular, two display devices can be interconnected and arranged to form a “large overall screen”.

[0021] A further aspect of the invention relates to a motor vehicle with at least one seat device according to the preceding aspect or with an arrangement according to the preceding aspect.

[0022] Furthermore, the invention also relates to a method for operating a seating device for a motor vehicle having at least one backrest, wherein the backrest has at least one display device for a person sitting behind the seating device on a rear side of the backrest.

[0023] It is provided that the display device is pivoted from a non-use position by means of a pivoting device into a use position for viewing by the person or vice versa.

[0024] Advantageous embodiments of the seating device are to be regarded as advantageous embodiments of the arrangement and the method. The seating device and the arrangement, in particular, have specific features enabling the corresponding method steps to be carried out.
