In addition, the invention relates to a headrest system for a motor vehicle, the headrest system having a headrest and a display head mounted device. The invention also relates to a seat device for a motor vehicle and a motor vehicle, the seat device having a headrest and a seat surface for an occupant of the motor vehicle. Background Art

[0002] At least partial and / or temporary autonomous driving of modern motor vehicles enables the occupants of the motor vehicle, in particular the driver, to gain time. However, the interior of known motor vehicles is not optimally designed for the possibly different interests of the occupants. The known entertainment possibilities and therefore also the possibility of abandoning them cannot be generally individualized in motor vehicles. Communication between the occupants is often made difficult by the entertainment possibilities and active entertainment possibilities must be overcome disadvantageously, for example by speaking loudly. The corresponding communication is again usually perceptible to all occupants and cannot be individually designed.

[0003] Common practice in motor vehicles includes the use of external entertainment devices for inputting and outputting entertainment content and / or dialogues. However, motor vehicles often have only simple and / or unfavorable connections of external entertainment devices and therefore have non-optimal coordination of the entertainment devices with the motor vehicle, in particular the infotainment system of the motor vehicle, and / or with each other. Summary of the invention

[0004] The object of the present invention is therefore to eliminate or at least partially eliminate the above-mentioned disadvantages of the prior art. In particular, the object of the present invention is to provide a headrest for a seat arrangement of a motor vehicle, with which the use of a display head mounted device can be realized in a particularly simple and advantageous manner. In particular, the object of the present invention is also to provide a headrest system for a motor vehicle, a seat arrangement for a motor vehicle and a motor vehicle.

[0005] The above-mentioned object is achieved by the patent claims. In particular, the object is achieved by a headrest for a seat device of a motor vehicle having the features of independent claim 1. In addition, the object is achieved by a headrest system for a motor vehicle having the features of independent claim 11, a seat device for a motor vehicle having the features of independent claim 12, and a motor vehicle having the features of independent claim 13. Further advantages and details of the invention are derived from the dependent claims, the description and the drawings. Features described in conjunction with the headrest according to the invention are of course also applicable in conjunction with the headrest system according to the invention, the seat device according to the invention, the motor vehicle according to the invention, and vice versa, respectively, so that the disclosures concerning the individual inventive aspects always refer to each other or can refer to each other.

[0006] According to a first aspect of the invention, this object is achieved by a headrest for a seat device of a motor vehicle, the headrest having a support surface for the head of an occupant of the motor vehicle, a receiving recess for receiving a display head mounted device, a detection device for detecting the display head mounted device in the receiving recess, a charging device for wirelessly supplying electric energy to the display head mounted device in the receiving recess, and a control device for controlling the supply of electric energy by the charging device based on the detection of the display head mounted device by the detection device.

[0007] Within the scope of the present invention, a display headset is to be understood as a combination of at least one loudspeaker, at least one microphone and at least one display. The display headset according to the invention can be worn on the head by an occupant. Preferably, at least one display is designed in an arcuate and / or helmet-like manner. Preferably, the display headset and / or the microphone comprise a noise reduction device (Rauschunterdrückung). Different structural designs of display headsets are basically known. The display headset according to the invention is preferably claimed primarily or only with respect to the interaction and / or interaction with the headrest according to the invention. Preferably, the headrest according to the invention can be used together with display headsets known on the market. The display headset is preferably to be understood as a wireless, in particular modular wireless, display headset.

[0008] The headrest has a support surface for the head of an occupant of a motor vehicle so that the headrest's function is essentially ergonomic and safety-related. The support surface is preferably padded at least in sections. In addition, the headrest according to the invention has at least one receiving recess for accommodating a display headset. Thus, the display headset can be placed by the occupant in at least one recess and / or in at least one receiving recess. Within the scope of the present invention, a receiving recess is to be understood as a device and / or volume for storing a display headset in a defined manner at the headrest and / or at least in sections in the headrest. At least one receiving recess can include a continuous receiving recess or a plurality of receiving recesses. Preferably, the receiving recess has a conical and / or chamfered area for guiding and / or positioning the display headset in the receiving recess in a defined manner. Preferably, the receiving recess has at least one bottom section parallel to the surrounding surface of the headrest. Preferably, the receiving recess has at least one pocket-shaped and / or slot-shaped volume for accommodating a display. Preferably, the receiving recess has at least one magnet and / or at least one latching device for aligning the display headset in the receiving recess and / or for guiding the display headset into the receiving recess.

[0009] For the sake of intuitive description and further understanding of the description, the display headset can thus be placed in a storage position in at least one receiving recess of a headrest or on the head of a user. When placed on the head of a user, the display headset preferably functions substantially according to known display headsets and is designed for outputting and inputting audio data.

[0010] Furthermore, the headrest comprises a detection device for detecting a display head mounted device in at least one receiving recess. The detection device detects whether a display head mounted device is arranged in at least one receiving recess of the headrest. The detection of the display head mounted device advantageously enables a control according to the detection described in detail below. The structural design of the detection device is described in the subsequent paragraphs. Intuitively described, the detection device identifies whether the display head mounted device is placed in a storage position in at least one receiving recess of the headrest.

[0011] In addition, the headrest has a charging device. The charging device is designed to wirelessly provide electrical energy to the display headset in the accommodating recess. Here, wireless provision should be understood as follows, that is, no wired connection is required, set and / or established between the display headset and the charging device for providing electrical energy. Here, for the feature of wirelessly providing electrical energy to the display headset, the extent to which the display headset and / or the headrest have cables respectively is irrelevant. The charging device is preferably designed to inductively wirelessly provide electrical energy to the display headset. The charging device is preferably arranged at least partially in sections in the headrest, preferably completely in the headrest. The charging device is preferably arranged in and / or at the headrest in the area of ​​at least one earmuff of the display headset and / or in the area of ​​the bow of the display headset. In other words, with respect to the installation position of the headrest, the charging device is preferably arranged in the lateral area of ​​the headrest and / or in the upper part of the headrest.

[0012] The control device according to the present invention can realize the supply of electric energy to the display head mounted device through the charging device according to the detection of the display head mounted device by the detection device. Intuitively speaking, if the display head mounted device in the accommodating recess is detected by the detection device, it is preferably possible to supply electric energy to the display head mounted device through the charging device. On the contrary, if the display head mounted device in the accommodating recess is not detected by the detection device, it is not possible to realize and / or prevent the supply of electric energy to the display head mounted device through the charging device. Preferably, the control device is energy-efficiently capable of realizing the following, that is, if the display head mounted device is not detected in the accommodating recess, the supply of electric energy to the display head mounted device is prevented electronically or mechanically. Within the scope of the description, the control device is defined as a component of the headrest, the seat device and / or the motor vehicle. Alternatively or additionally, the control device is designed as a functional unit together with an existing control device of the seat device and / or the motor vehicle.

[0013] Preferably, the headrest has an electrical interface for electrical connection to a seat device described later and / or a motor vehicle, and / or a mechanical interface for mechanical connection to a seat device. Alternatively or additionally, the headrest is designed in one piece with the seat device, for example in the form of a seat shell.

[0014] A headrest designed in this way is particularly advantageous because it allows the use of a display headset particularly easily, wherein the control device can particularly easily provide electrical energy via the charging device as a function of the detection of the display headset by the detection device.

[0015] According to a preferred improvement of the present invention, it can be arranged in the headrest that the headrest includes a data interface, wherein the data interface is designed for wireless data transmission with a display head mounted device, wherein the control device is designed to control the wireless data transmission through the data interface according to the detection of the display head mounted device by the detection device. The data interface is preferably designed to be inside the headrest or to be designed to be separated from the headrest. Wireless data transmission should be understood similarly to the wireless provision of electrical energy described above, that is, no wired connection is required, not provided and / or established between the display head mounted device and the data interface for data transmission. Here, for the feature of wirelessly providing electrical energy to the display head mounted device, the extent to which the display head mounted device and / or the data interface have cables respectively is irrelevant. The data interface is preferably designed to transmit data to the display head mounted device via a known standard (e.g., Bluetooth, in particular at least Bluetooth 5 or at least 5.3). Within the scope of the present invention, controlling the wireless data transmission via the data interface in dependence on the detection of the display head mounted device by the detection device is to be understood as follows: if the display head mounted device is not detected in the receiving recess, the wireless data transmission to the display head mounted device is designed according to a first transmission logic, and if the display head mounted device is detected in the receiving recess, the wireless data transmission to the display head mounted device is designed according to a second transmission logic. The first transmission logic is designed differently from the second transmission logic. Within the scope of the present invention, the transmission logic is to be understood as a logic for processing the data transmission between the headrest and the display head mounted device. Within the scope of the description, the data of the data transmission is preferably to be understood as an audio signal and / or a video signal. A headrest designed in this way is particularly advantageous because wireless data transmission to the display head mounted device can be realized via the data interface, wherein the control device is designed to control the wireless data transmission via the data interface in dependence on the detection of the display head mounted device by the detection device.

[0016] According to a preferred improvement of the present invention, in the case of a headrest, it can be arranged that the data interface is designed for wireless data transmission of incoming audio data, outgoing audio data and outgoing display data with a display head mounted device, wherein the control device is designed to independently control the wireless data transmission of incoming audio data, outgoing audio data and outgoing display data through the data interface according to the detection of the display head mounted device by the detection device. It is particularly advantageous that the data interface is designed for wireless transmission of incoming audio data, outgoing audio data and outgoing display data with a display head mounted device. The incoming and outgoing audio data preferably include audio signals that can be output by the display head mounted device and / or received by the display head mounted device. For better understanding, the data interface is defined as a reference device for audio data and display data, so that the outgoing audio data is preferably display head mounted device speaker data, and the incoming audio data is preferably display head mounted device microphone data. The outgoing display data preferably includes video data for output on a display of the display head mounted device. The combination of the data interface and the control device is particularly advantageous because, according to this improved solution, the control device is designed to independently control the wireless data transmission of the incoming audio data, the outgoing audio data and the outgoing display data via the data interface in dependence on the detection of the display head mounted device by the detection device. Thus, it is possible, for example, that when the display head mounted device is positioned in the receiving recess and is detected accordingly by the detection device, the outgoing audio data and / or the outgoing display data of the data interface are not sent to the display head mounted device and are therefore not output on the display head mounted device. However, despite the fact that the display head mounted device is positioned in the receiving recess and is detected accordingly by the detection device, the independent control of the wireless data transmission continues to enable the reception of the incoming audio data by the microphone of the display head mounted device and the corresponding data transmission from the display head mounted device to the data interface. Thus, by way of example, the use of the microphone of the display head mounted device continues to be enabled while avoiding the audio output and / or the video output on the display head mounted device in the receiving recess. In other words, when the display headset is arranged at the headrest, a headrest designed in this way can, for example, achieve that the sound does not come from the display headset speakers and / or the video signal is not presented on the display because they are placed and / or covered at the headrest. In contrast, the display headset microphone continues to be usable; in such a way that it is arranged at the headrest, the microphone can be turned forward and / or pulled out and used as usual in order to improve voice reception. A headrest designed in this way is particularly advantageous because wireless data transmission to the display headset can be achieved via a data interface, wherein the control device is designed to independently control the wireless data transmission of incoming audio data, outgoing audio data and outgoing display data via the data interface based on the detection of the display headset by the detection device.

[0017] According to a preferred improvement of the present invention, in the case of a headrest, it can be provided that the accommodating recess is designed to at least partially, in particular completely, accommodate a bow of a display head-mounted device, at least partially, in particular completely accommodate at least one earmuff of the display head-mounted device, at least partially, in particular completely accommodate a display of the display head-mounted device, and / or accommodate the entire display head-mounted device in the headrest. Preferably, the accommodating recess is designed to surround the headrest in partial sections. With respect to the installation position of the headrest, the accommodating recess is preferably designed at the headrest above and laterally. The accommodating recess preferably corresponds to the negative shape of the display head-mounted device or substantially corresponds to the negative shape, or corresponds to the negative shape of a generally commonly used display head-mounted device shape. Preferably, the accommodating recess includes a continuous or separate recess for at least one earmuff of the display head-mounted device, at least one bow of the display head-mounted device, and / or at least one display of the display head-mounted device.

[0018] The receiving recess preferably has at least one positioning device, in particular wherein the at least one positioning device is arranged asymmetrically on the headrest and / or in the receiving recess in order to enable the display headset to be accommodated in only one orientation. A headrest designed in this way is particularly advantageous, since the receiving recess enables the display headset to be advantageously accommodated at least in sections in the headrest.

[0019] According to a preferred improvement of the present invention, in the case of a headrest, it can be provided that the detection device includes a mechanical, electrical and / or inductive sensor device for detecting a display head mounted device in the accommodating recess. The detection device is preferably designed in a sensory, electronic, mechanical and / or inductive manner. The detection device preferably includes at least one sensor device, particularly preferably at least two or more sensor devices, for detecting a display head mounted device in the accommodating recess. Preferably, the detection device is designed in such a way that an incorrect arrangement of the display head mounted device in the accommodating recess can also be detected. Preferably, when an incorrect arrangement of the display head mounted device in the accommodating recess is detected, an optical and / or acoustic signal is output via the display head mounted device, the headrest and / or the motor vehicle. A headrest designed in this way is particularly advantageous because the detection device enables an advantageous detection of the display head mounted device in the accommodating recess.

[0020] According to a preferred improvement of the present invention, in the case of a headrest, it can be provided that the headrest includes at least one speaker, wherein the control device is designed to control the output of the at least one speaker according to the detection of the display headset by the detection device. Preferably, the at least one speaker is integrated in the headrest at least in sections. Alternatively or additionally, the speaker can be arranged outside the headrest. The control of the output of the at least one speaker should preferably be understood as the control of the data transmission of the audio signal to the at least one speaker. Preferably, the headrest thus enables the output of the outgoing audio signal through the at least one speaker, especially when the display headset is detected in the receiving recess by the detection device. Therefore, by way of example, the above-mentioned use of the display headset microphone can continue to be achieved, while avoiding the audio output on the display headset in the receiving recess. In other words, when the display headset is arranged at the headrest, the headrest designed in this way can, by way of example, achieve that the sound does not come from the speaker of the display headset, because it is placed and therefore covered on the headrest, but from the speaker of the headrest. The headrest designed in this way is particularly advantageous because when the display headset is arranged in the receiving recess, the audio data can be outputted advantageously, in particular individually, through the speaker.

[0021] According to a preferred improvement of the present invention, in the case of a headrest, it can be provided that the headrest comprises at least one holding device, wherein the holding device is designed to hold the display headset in the receiving recess in a holding and / or locking manner, in particular wherein the at least one holding device is designed to hold the display headset, the bow, the display and / or the at least one earmuff in a holding manner. Preferably, at least one holding device has an initial resistance for inserting into the receiving recess and / or removing the display headset. Preferably, at least one holding device is designed to be elastically deformable. Preferably, at least one holding device has a spring device. Preferably, at least one holding device comprises at least one magnet, at least one clip and / or at least one plug connection. Preferably, the headrest has at least two or more holding devices, in particular wherein at least two or more holding devices are evenly and / or symmetrically arranged on the headrest. Preferably, at least one holding device comprises an ejection device, such as a button, for advantageously ejecting and / or releasing the display headset from at least one holding device and / or from the receiving recess. Preferably, at least one holding device is designed to be rotatable and / or pivotable. Preferably, the detection device can detect that the display headset is received in the receiving recess in a holding and / or locking manner by the holding device. Particularly preferably, the control device can provide electrical energy by the charging device based on the detection that the display headset is received in the receiving recess in a holding and / or locking manner by the holding device. In other words, preferably, the supply of electrical energy can only be achieved when the correct, holding and / or locking reception of the display headset is detected. A headrest designed in this way is particularly advantageous because the holding device can advantageously receive the display headset in a holding and / or locking manner, and thus safe positioning of the display headset, accident protection and / or avoidance of loose parts in the interior of the motor vehicle can be achieved.

[0022] According to a preferred improvement of the present invention, in the case of a headrest, it can be arranged that the headrest is designed as a sleeve-type headrest. And it has a cavity for putting the headrest on the conventional headrest as an add-on and at least one closing device for closing the cavity at least in sections. The cover headrest is to be understood as a retrofit solution for conventional headrests that do not have the technical function of the headrest according to the invention, for example. For this purpose, the headrest according to this design has a cavity, with which the cover headrest can be covered on the conventional headrest. In order to be fastened to the conventional headrest, the cover headrest preferably has at least one fastening device, such as Velcro, elastic band, rope, button and / or snap. The cover headrest preferably has at least one interface for electrical, data communication and / or mechanical connection to the seat device and / or the motor vehicle. The headrest designed in this way is particularly advantageous because the cavity and the design as a cover headrest can realize an advantageous retrofit solution for conventional headrests at low cost and expense.

Therefore, the use of the microphone of the display headset 120 can continue to be achieved, while avoiding the audio output and / or video output on the display headset 120 in the receiving recess 30. In other words, when the display head mounted device 120 is arranged on the headrest 10, the headrest 10 designed in this way can, for example, achieve that the sound signal does not come from the speaker of the display head mounted device 120 and / or the video signal is not presented on the display 126 of the display head mounted device 120 because it is placed, arranged and / or covered on the headrest 10. On the contrary, the microphone of the display head mounted device 120 continues to be usable; in a manner arranged on the headrest 10, the microphone can be rotated forward and / or pulled out and used as usual to improve voice reception.
