Description

The invention relates to an ergonomic system according to the preamble of claim 1, in particular an intelligently controlled ergonomically optimized seating system and a method for ergonomically adjusting a workplace according to the preamble of claim 19.

Many professionals spend most of their working time sitting. Sitting for too long, the associated lack of exercise and an unsuitable or rigid sitting posture have an impact on their performance and health, especially for people who work permanently. In particular, this can cause damage to the spine, the heart and the entire musculature and impair the metabolism. In addition, permanent sedentary work can also be the cause of mental illnesses or at least favor them. In addition to an unfavorable seating position, other workplace conditions, such as room temperature or disturbing noises, especially in open-plan offices, also affect performance and health. Systems which are aimed at adapting individual working conditions to the respective user are known from the prior art.

From the German patent application DE 10 2013 109 830 A1 For example, an ergonomic system for a workplace system with height-adjustable furniture emerges. The ergonomic system comprises a data processing device and an image recording device connected to the data processing direction. The image recording device creates an image of a user of the workstation system and transmits the image files to the data processing device. The data processing device is connected to an ergonomics database. On the basis of the image data, a measure for the correctness of a corresponding position and posture of the user is determined. The level of correctness is then signaled to the user via light-emitting diodes or a display on a mobile phone or a computer.

The user is encouraged to behave ergonomically by signals, but the recommended settings are often not or not correctly implemented. The signals displayed are no longer perceived after a short time or are deliberately ignored. In particular, information that indicates a suitable seating position is often not implemented or is not implemented correctly.

To set a suitable or comfortable seating position, office chairs often have several elements that allow the user to individually adjust the office chair. However, the users are often not aware of all of the available setting options, or the numerous setting options make the user feel overwhelmed when setting the office chair. The user often selects an office chair setting that is unsuitable for him. Even with a suitably adjusted office chair, it is not taken into account that the optimal seat setting changes over the course of the day due to the seating behavior and the respective physical performance physiology of the user and must be continuously adapted to the respective user profile.

The object of the invention is to provide a holistic ergonomic system and a method for adjusting the ergonomic system, which in particular ensures a suitable sitting position of the user.

The invention achieves this object by means of an ergonomic system having the features of claim 1 and a method having the features of claim 19. Advantageous refinements and useful developments of the invention are specified in the dependent claims.

The ergonomic system mentioned at the outset comprises a data processing device, an office chair which comprises at least one chair foot and a seat connected to it, and a user detection device for detecting the face and / or for detecting the seating position of a user arranged on the office chair. The user detection device can consist of several cameras for detecting movements of the face, in particular the eyes, and the body of the user. The determined image data and / or seat position data of the user detection device are transmitted to the data processing device. Furthermore, the ergonomics system includes a database which is connected to the data processing device and contains, among other things, data for a preferred suitable seating position of the user. The database contains, in particular, medically based data on a suitable sitting position, which are specifically geared towards moving or dynamic sitting. Personal data of the user can also be stored. On the basis of the data in the database and the visual observation and / or the seat position data of the user detection device, the data processing device continuously determines a suitable seat position desired for the user. In particular, health-promoting measures are identified. The preferred local database can are in particular in connection with a global ergonomics database in order to retrieve data and to transmit recorded data of the user to them. This enables continuous optimization of the ergonomic system based on the determined data. In particular, machine learning enables self-optimization of the ergonomic system, in particular the database.

According to the invention, the ergonomic system is characterized in that parts of the office chair can be actively controlled by the data processing device to adjust the desired suitable seating position. In particular, the seat can be connected to the chair foot via a bearing that can be adjusted for the inclination of the seat, the bearing being controllable via the data processing device.

This makes it possible to bring the seat position of the office chair, in particular the seat, but also other parts of the office chair, into a preferred position from a medical point of view on the basis of the captured image data and / or the seat position data of the user detection device and the data from the database. Signaling that is intended to animate a user to assume a predetermined sitting position is not necessary.

The adjustment of the inclination of the seat or other parts of the office chair can in particular take place automatically. This can ensure that a preferred or the desired suitable seating position is actually assumed. The ergonomic system according to the invention thus provides permanent autonomous control without the intervention of the individual user. The movement of the seat surface or other parts of the office chair can in particular take place in such a way that the user does not or hardly perceive it and is not disturbed in his work. However, a consciously perceptible movement of the seat or other parts of the office chair, which, for example, actively initiates the user to stand up, is also possible. In particular, it is also possible to align the actuation of the seat surface or other parts of the office chair to the training of a specific body region, in particular specific muscle parts of the back. For example, a certain back section, e.g. a weakened back section is trained specifically or a back-friendly sitting position is set. In particular, the personal needs of a user can be taken into account, for example by entering and storing appropriate medical or therapeutic data in the database. In the event of complaints from the user, the recorded data of the ergonomic system can also be used for further treatment measures, for example for further therapeutic measures by a physiotherapist. Furthermore, it is also possible, in addition to the automatic activation of the seat surface or other parts of the office chair, to additionally output signals or information, for example via displays on a screen or light signals, which also inform the user. For example, information about other supporting measures can also be provided. The ergonomic system enables the user to have a direct effect on health and performance, in particular also on concentration. In addition to taking into account the previous seating position, previous seating positions or movements of the user detected by the user detection device can also be taken into account when determining a desired suitable seating position.

In an advantageous embodiment of the ergonomic system, the storage or other parts of the office chair can be automatically controlled to change the inclination of the seat surface on the basis of the data in the database and the data in the user detection device after certain time intervals. In particular, this prevents the user from remaining in a sitting position for an extended period of time and damage from a rigid sitting posture occurring. A suitable sitting position is in particular also dependent on the duration in which the user is in this sitting position. At predetermined time intervals, it can be prevented that the seat surface is actuated continuously, for example, each time the user's body movement is detected by the movement detection device. Continuous activation of the seat surface could in particular also have disruptive effects on the work of the user and create an uneasy working atmosphere. Rather, an automatic control of the seat surface is provided after certain predetermined time intervals. For the determination of a desired suitable sitting position by the data processing device, in particular a suitable inclination of the seat surface, the image data and / or seat position data of the user detection device, which reflect the previous sitting position and the movements of the user, are averaged within the time intervals. The time intervals can be predetermined or can be continuously and individually calculated, in particular also on the basis of detected movements and the type and frequency of the movements of the user.

The seat surface can preferably have sensors for detecting the seat position and / or the weight of the user or a local load on the seat surface. The sensors are included connected to the data processing device. In combination with the data of the user detection device in particular, this enables precise information about the sitting posture and the determination of a suitable sitting position of the user. The detection of local loads on the seat surface makes it possible, in particular, to detect incorrect loads and to control the seat surface accordingly.

In a further embodiment, the office chair can have a chair base which is height-adjustable via the data processing device and / or via a manually operable lever. This allows a further adaptation of the ergonomic system to a seating position suitable for the user, in particular the adaptation to the size of the user and to the height of a work table. The work table can also be part of the ergonomic system, in particular the height and inclination of the table top can be designed to be controllable by the data processing device.

In a preferred embodiment, the office chair can comprise a back part which can be controlled by the data processing device and / or manually by a lever. In particular, the back part can also include sensors for detecting the user's sitting position, which are connected to the data processing device. The back part can particularly preferably consist of a plurality of separately controllable units, in particular a backrest, which for example comprises a lumbar support, and a headrest. The backrest in particular can be divided into further adjustable sub-units, each of which can be equipped with sensors. This enables an exact detection of the sitting position, in particular the detection of the back of the user, as well as an adjustment of the office chair adapted to the back. With such a configuration of the back part, individual areas of the back can be supported in a targeted manner. In particular, by adapting the contact pressure and adjusting the height of the backrest and adjusting the headrest, the back part can be adapted to the needs of the user.

The holistic ergonomic system according to the invention can preferably have a noise suppression unit. The noise suppression unit advantageously comprises a sound sensor for recording the ambient noise and a loudspeaker system for generating destructive interference. The noise suppression unit can work autonomously or can be connected to the data processing device. The ambient noise detected by the sound sensor is analyzed, a corresponding destructive interference is calculated and this is output via the loudspeaker system. This makes it possible to block out disturbing ambient noise and create a quiet working atmosphere for the user. This promotes in particular the concentration, the performance and the well-being of the user. The noise suppression unit or at least parts of the noise suppression unit is particularly preferably integrated in the back part of the office chair, in particular in the headrest. It is particularly advantageous if the sound sensor and the loudspeaker system are arranged in the back part and thus directly on the ears of the user. This enables local noise suppression in the area of the office chair without the use of additional headphones.

In a further embodiment, the ergonomic system can comprise an air conditioning unit connected to the data processing device. The air conditioning unit comprises at least one air conditioning sensor, which in particular detects the ambient temperature and / or the air humidity. In addition, the air conditioning unit can have an air conditioning unit that can be controlled via the data processing device. This makes it possible to act on the climate surrounding the workplace, in particular the office chair, in order to create a pleasant working atmosphere for the user. In particular, the temperature and / or the humidity can be adjusted. It is also possible to take into account the climatic working conditions that are pleasant for a user in order to further increase the well-being of the user.

In an advantageous embodiment, the ergonomic system can have a lighting unit connected to the data processing device. The lighting unit comprises at least one light sensor for detecting the brightness and / or the color temperature of the ambient lighting. In addition, the lighting unit can comprise a light system that can be controlled via the data processing device. According to the data recorded by the light sensor, the data processing device can control the light system in order to set a brightness and / or color temperature of the ambient lighting that is suitable for the user. Here too, it is possible to take into account the settings that are personally pleasant for a user. As a result, a working atmosphere suitable for the user is also generated with regard to the ambient lighting. In particular, damage to the eyes can also be counteracted by working in unfavorable lighting conditions. Suitable lighting conditions also have a positive effect on the psyche of the user.

Furthermore, the ergonomic system can have a screen connected to the data processing device, in particular the screen connected to a work computer. In particular, the brightness of the screen can be controlled by the data processing device and can be adapted to the needs of the user, in particular also taking into account further conditions of the workplace, such as the ambient lighting or the user's sitting position. In addition to the brightness, the data processing device can also control other parameters of the screen, for example the screen resolution.

In a first advantageous embodiment, the bearing of the office chair can be a spring bearing, with a lower plate which is connected to the chair base, an upper plate which is connected to the seat surface or forms the seat surface, and arranged between the lower and the upper plate Spring elements. The spring elements each have a controllable adjusting screw for adjusting the respective spring force of the individual spring elements. The adjustment screws can be controlled via the data processing device. A control unit, in particular a motor unit, which can be controlled via the data processing device is particularly preferably assigned to the adjustment screws. This results in a simple and robust design of the bearing in terms of production technology, which enables the inclination of the seat surface to be set precisely via the data processing device. In particular, the setting of a rebound of the seat under load is also given. This is particularly advantageous for cushioning a movement of the user, especially when sitting down.

In a second advantageous embodiment, the bearing of the office chair can be a roller bearing with a bearing element, in particular a bearing ring, which is connected to the chair base and a spherical shell arranged on the bearing element, which is connected to the seat surface or forms the seat surface. The bearing element has roller elements that are connected to the spherical shell. Alternatively, it is also possible for the spherical shell or the spherical shell and the bearing element to have the roller elements. The roller elements can be controlled via the data processing device. A control unit that can be controlled via the data processing device, in particular a motor unit, is particularly preferably assigned to the roller elements. The above-mentioned advantages of spring mounting are also given when designing the mounting as a roller mounting.

In a third advantageous embodiment, the bearing of the office chair can be a levitation bearing, with a bearing element, in particular a bearing ring, which is connected to the chair base, and a spherical shell arranged on the bearing element, which is connected to the seat surface or forms the seat surface. At least one of the two elements, the bearing element or the spherical shell, comprises a permanent magnet or is designed to generate a magnetic field. The other element is magnetic, in particular diamagnetic, or also designed to generate a magnetic field. The bearing element and the spherical shell can be spaced apart and aligned with one another by magnetic interactions. The magnetic field of the bearing element and / or the spherical shell can be controlled via the data processing device. The above-mentioned advantages of spring mounting are also given when the mounting is designed as a levitation mounting, with a particularly precise adjustment of the inclination of the seat surface being possible.

A method according to the invention for the ergonomic setting of a workplace with an ergonomic system according to the invention is characterized in that the data processing device receives data from the ergonomic system, in particular the image data of the user detection device and data from further sensors, and a preferred setting of the ergonomic system, in particular the sitting position, based on the data from the database of the user. The ergonomic system is then specifically controlled according to the determined or calculated settings. In particular, the inclination of the seat surface or other parts of the office chair is suitably adjusted. The method enables a suitable continuous adjustment of the holistic ergonomic system. This leads to an improvement in performance, health and well-being of the user. The recorded data make it possible, in particular, to improve the ergonomic system, in particular through machine learning, and to adjust the ergonomic system to the needs of the respective user.
