DETAILED DESCRIPTION OF THE DRAWINGS

[0024] Parts corresponding to one another are provided with the same reference numerals in all figures.

[0025] FIG. 1 shows a seat system S having a vehicle seat 1, a control unit 2, a display unit 3 and a camera 4, the detection range of which is directed at the vehicle seat 1. In addition, the seat system 5 comprises moveable elements 5 and pressure sensors 6 which can be controlled by means of the control unit 2 and are integrated in a seat cushion 1.1 forming a seat surface and in the seat back 1.2.

[0026] The moveable elements 5 are in particular so-called massage bubbles, which are arranged in predetermined areas of the seat cushion 1.1 and the seat back 1.2.

[0027] A vehicle seat 1 designed as a massage seat, which requires interaction with a user, in particular a driver of the vehicle, is known from the prior art.

[0028] Sitting leads to hardly any or to one-sided static muscle work of the user, which may cause pain and discomfort. In addition, monotony and consequent inattention and fatigue of the user can frequently occur during comparatively long motorway journeys.

[0029] In order to improve, in addition to a level of comfort, in particular a level of seat comfort, a physical activity of motor functions, in particular coordinative abilities, of the user on the vehicle seat 1, the seat system S and a method described below, in particular for carrying out a training program for the user, i.e., for an occupant on the vehicle seat 1, are provided.

[0030] The method with respect to the seat system S can be applied to any sedentary activity, wherein the application is not limited to the vehicle seat 1, which can be arranged in any vehicle. It is also conceivable that the seating system S can comprise a piece of furniture, in particular an office chair.

[0031] The seating system S is designed in such a way that it predetermines a movement to be performed by the user in the form of muscle training. Here, a feedback to the user takes place as interaction.

[0032] As described above, the seating system S comprises the moveable elements 5 and the pressure sensors 6 for this purpose, wherein the user has the option of activating and deactivating the execution of the muscle training.

[0033] According to the present exemplary embodiment, a prompt to perform muscle training is output to the user on the vehicle seat 1 by means of a visual output on the display unit 3.

[0034] Alternatively or additionally, a signal can also be output acoustically and/or haptically as a prompt.

[0035] Preferably, instruction is given in haptic form by controlling the moveable elements 5, wherein visual clarification via the display unit 3 is conceivable.

[0036] The user can confirm or reject the execution of the muscle training.

[0037] By way of example, the user is prompted to press against the seat back 1.2 with his right shoulder. By means of at least one pressure sensor 6 arranged in the corresponding area of the seat back 1.2, the pressure exerted by the shoulder on this area is detected. Based on detected signals of the pressure sensor 6, which are fed to the control unit 2, a temporal and spatial correspondence of the executed movement of the user with a specification of the seat system S is determined. Thus, a deviation between the exerted pressure as input signal E and a specification as output signal A is determined, as shown by means of the block diagram in FIG. 2.

[0038] In particular, the detected input signals E of the at least one pressure sensor 6 compared to the output signal A are used to determine whether the user is pressing as fast as possible and in the correct position of the vehicle seat 1, wherein it is also determined whether more body areas are involved in the application of pressure than required. Thus, the aim of the muscle training is for the user to learn to perform his/her movement more precisely.

[0039] Thus, the output signal A is compared with the input signal E, wherein the comparison refers to the temporal as well as the spatial correlation between the output signal A and the input signal E. The input signal E is thus evaluated not only in terms of an amplitude of the pressure exerted, but also in terms of whether the pressure sensor 6 assigned to the required area was actuated at a certain time.

[0040] Such an algorithm for comparing the input signal E with the output signal A enables an assertion about a coordination of the user. By means of the display unit 3, the amplitude of his/her exerted pressure can be displayed as information.

[0041] The camera 4 as a component of the seat system S continuously captures image data, wherein additional movements of the user in the space can be detected and, if necessary, taken into account during the execution of the muscle training. Thus, not only quasi-isometric movements but also more complex movements in the space, in particular in the vehicle, can be detected. These can be used as an extension of the training content and to correct the training.

[0042] In one embodiment of the seating system S, the user's breathing is detected while performing a motor task, i.e., during a training session. Thereby, corresponding to scientific literature, the user is given a cue to exhale during a muscle contraction, i.e., during the application of pressure to the required area of the vehicle seat 1, and to inhale during the release of pressure on the muscles.

[0043] A rhythm of the user's breathing is compared to a predetermined rhythm, wherein a deviation is determined and it is indicated to the user whether his/her breathing has the predetermined rhythm.

[0044] Furthermore, the method provides that a training process is offered to the user based on the detected input signals E and the output signals A. By means of a corresponding algorithm, the user is assigned to a training level based on the detected input signals E of the seat system S, which can be displayed to the user as feedback. During a training process, increasingly difficult sequences, i.e., training sessions are offered, whereby the complexity of the muscle training is increased.

[0045] Depending on the determined training level, an exercise can be selected as the next training session for the user, such that the user's training level and a training goal are taken into account. By means of the seating system S, after the user has used the seating system S several times, user-specific muscle training is possible. By way of example, the user can be identified based on detected signals from the pressure sensors 6 and/or based on detected image signals from the camera 4 and/or based on other information provided in the vehicle. Once the user has been identified, a suitable training session can be selected, also depending on the training level in relation to previous muscle trainings. For this purpose, for example, user data N can be detected and stored.

[0046] Another possible embodiment provides that the input signals E and the output signals A are used in order to offer the muscle training to the user in a game-like manner. In particular, body movements of the user can be used as a control signal for the game. It is also possible that the user's body movements on the vehicle seat 1 are additionally used as a further input and/or control element.

[0047] If several seats 1 are part of the seating system S, the input signals E of the vehicle seats 1 can be compared with one another, such that a comparison between several users is possible. The users can thus, for example, perform a joint muscle training and/or a competition. The competition can also be performed against a computer unit not depicted in more detail.

[0048] In a possible development, the completion of a training session can be represented, for example, by means of a score, wherein the scores of multiple users are compared via a digital path, for example, by means of an application program on a respective mobile device of the respective user.

[0049] By way of example, the performance of the muscle training can be used to detect a driver state. By way of example, the training session can be selected as a training or game recommendation during a driving session, such that the training session contributes to driver state optimisation.

[0050] It is also conceivable that the user is offered the performance of a training session depending on a state Z determined on the basis of detected image data of the camera 4, in order to increase the user's attention, i.e., to improve the state Z in relation to driving operation.

[0051] Alternatively or additionally, detected vehicle data D represent input variables of the seat system S. By way of example, a detected current vehicle position and/or detected signals of at least one acceleration sensor of the vehicle are used as vehicle data D. Based on the vehicle data D, a current driving situation can be taken into account in order to predetermine a training level which is at least optimised for the user. In particular for improving the driver's condition, e.g., to counteract a monotony of the driving operation, the inclusion of the vehicle data D appears to be useful.

[0052] By means of the seat system S and the method for operating the seat system S, the quality of movements of the user can be improved, wherein, due to the fact that the muscle training is performed during the driving operation of the vehicle, the user performs so-called double task training. On the one hand, the user performs the driving task as the driver, and on the other hand, he/she completes the muscle training.
