Abstract

The present invention allows a large (unrestricted) circle of users to quickly and conveniently set, change and reproduce office chair configurations, and a variety of settings can be stored, changed and retrieved using a central computer or other stationary or mobile storage medium and this user-related data is protected against unauthorized access and accessible only to the respectively legitimized / authenticated user.

Description

The invention relates to devices and methods for setting and storing positions, preferably in seating and for the reproduction of stored positions.

Seating, especially office chairs, can have a variety of options for setting seating positions, such as a height, length, tilt adjustment of elements, in particular seat, backrest, headrest, footrest and armrest.

In the following, the terms office chair or chair are understood in particular to be synonymous with all types of furniture, chairs, loungers, flaps, doors, windows and other adjustable elements in the private or commercial mobile and stationary sector.

In particular, in motor vehicles electrically adjustable seats are known, which allow a reproduction of previously set and stored seating configurations (so-called seats with memory function). For storage and reproduction of the seat configuration here is often a keypad, which is generally connected via a CAN bus to a controller.

Furthermore, home or lounge furniture is also known in the domestic field (for example comfort armchairs, wellness armchairs), which have electrical adjustment options, sometimes supplemented by other functions, such as, for example, Massage or heating.

Adjustment mechanisms for this are in the form of kinematics, gearboxes, deflections, racks, spindles, cams, guides, fittings, hydraulics, etc. well known.

The disadvantage here is that the number storable positions, according to the number of existing keys, is limited and also each user has access to all stored seating configurations and can retrieve or change them as desired.

In many cases, the actuation of the respective adjustment mechanism by means of muscle power by the user. In other cases, this controllable actuators, for example in the form of electric motors with / without gear provided. The controllable actuators may have sensors, for example, for a position and / or load detection or such information may be obtained from the actuator, for example in the form of a motor current, a voltage, a phase relationship or a frequency. The actuators can also be operated in a regulated manner in conjunction with sensory information, for example to approach a certain position or to enable pinch protection.

For operation, motor-actuated seating furniture can have input means, for example in the form of a keypad, by means of which the user can approach desired and possibly perceived as pleasant, efficient or ergonomic positions.

The energy required for the Aktuierung by a stationary power source, such as the power grid, with which, for example, an office chair, at least during the Aktuierung is connected, or by an energy storage, preferably a rechargeable energy storage, particularly preferably a wirelessly rechargeable energy storage, such as one via electromagnetic Fields rechargeable accumulator, be provided.

In modern work environments, employees are often assigned changing jobs. Setting the desired positions of the office chair located at the respective workstation is time-consuming and inefficient in terms of an optimal workflow. In addition, to perform different activities, e.g. Desk activities or meetings, various positions of the office chair be useful, but their adjustment or reproduction is time-consuming.

As far as available, the number memory-retrievable positions of an electrically actuated office chair is limited to a few users and not protected from unauthorized access by third parties.

The object of the present invention is to allow a large (unrestricted) user group a quick and comfortable setting, change and reproduction of positions or seat configurations of an office chair, with a variety of settings being stored by means of a central computer or other stationary or mobile storage medium These user-related data are protected against unauthorized access and are only accessible to the respectively legitimized / authenticated user.

This object is achieved by means of an office chair according to claim 1. Advantageous developments of the invention are the subject of the dependent claims.

An office chair according to the invention has at least sensors, in particular for detecting the position of seat elements or seat structures, as well as Means for communication, power supply, storage and authentication of office chair and user and for communication with a local or network computer or a smartphone and their memory (possibly cloud) on and at least one user interface on at least one terminal, wherein the seat adjustment manually, partially manually or can be electrically actuated.

By storing and retrieving seating positions and seating configurations, particularly height, distance and inclination of seating elements from a store, manual reconfiguration is greatly facilitated and, in the case of motorization, allows fully automated seat adjustment. In particular, it is possible for each authorized user to store at least one, but preferably a number of seat positions or seat configurations related to him, and retrieve them on request.

In a particularly advantageous manner, this object is achieved by an office chair with electrically actuable seat elements, which allows a motorized reproduction of seating positions from the memory.

• 12 an office chair in relaxed position of the seat
• 13 an office chair with parallel kinematics and a mounting of the adjusting motors on the pedestal
• 14 an office chair with one, in the same sitting position as 13 , alternative position of parallel kinematics

In a first exemplary embodiment or a first expansion stage, the office chair has sensors, in particular for detecting the position of the seating elements, as well as communication means with energy supply, memory and identification means for authenticating the office chair and the user and a user interface on a computer or a smartphone.

In conjunction with a preferably graphical user interface, the user is able to easily and quickly retrieve and manually reproduce a seat configuration already made and stored, or from a collective of several seat configurations stored by him.

On the one hand, the office chair uses wireless communication to transfer the current chair parameters to an external data processing, display or input device. On the other hand, user-specific seat configurations may be retrieved from memory, e.g. Cloud, to be loaded on the external display / input device. This process may be preceded by an authentication of the user and / or a type identification of the office chair.

A comfortable seat adjustment can be achieved, inter alia, that the user the current actual positions of the seat elements and to be approached, loaded from the memory, target positions are displayed and the user, possibly supported by appropriate references to the location of the Adjustment devices and instructions for their operation, eg a direction of rotation, this manually operated until match each setpoint and actual position.

Particularly preferred for this purpose is a graphical user interface that visually or graphically, possibly symbolically, the office chair with the desired and the actual positions and the position of the adjustment of the chair model concerned, so that the settings intuitively, for example by means of a zero balance , can be performed. In support of this, the correct actuating direction of the adjusting devices can be displayed. For example, on the display device, the desired position of a backrest and its actual position, which may be different in inclination, height and distance from the seat, be graphed, so that the user in the form of a synchronous with the manual adjustment on the Display device moving backrest receives optical feedback in near real time. A corresponding feedback can also be made acoustically, for example by a pitch or volume proportional to the deviation. The coincidence of desired and actual position can be brought to display eg by flashing, intensity or color change of the backrest symbol on the display device and / or acoustically or by vibration, whereby the adjustment process for the inclination parameter backrest can be completed.
In the same or similar way further chair parameters can be reconfigured.

Compared to today's tedious trial and error, the quick retrieval of seating positions and the comfortable reconfiguration of the seating parameters already represents a significant improvement in the workflow with increased ease of use.

Similarly, manually set seat configurations may be stored in a memory of a central computer, a seat control device, a smartphone or other storage medium and retrieved as needed. Advantageously, the various seat configurations personal and labeled and only retrievable or modifiable after authentication.

Particular advantages of the inventive solution are that office chairs equipped with little effort with the necessary sensors, data transmission, storage and power source, etc. and in particular existing chair models without significant interference with the seat mechanism can hereby be retrofitted.

From the customer's point of view, not only the quick and easy reconfiguration of a particular chair is a great advantage, but also the transferability of the positions and seating configurations found in a particular chair model to other chair models. Ensuring such transferability of seating positions across different chair models of a manufacturer or between chair models of different manufacturers, can be achieved for example by appropriate databases in which the geometries of the chairs and other chair parameters are stored and to which the communication structure of the chair has access.

Another aspect of the invention, while ensuring the required degrees of freedom, an embodiment for the seat kinematics, also referred to as chair kinematics or adjustable support structure specify, which is easy to motorize and characterized by low complexity, a low number of components and a scalability different sizes and shapes of chairs.

This shows 2 For example, an embodiment of the chair kinematics in the form of a motor-driven parallel kinematic, which on the one hand with a pedestal 3 and on the other hand with the seat structure 6 , at least having a seat 24 , connected is. Advantageously, the in 2 and the following ones 3 to 14 illustrated office chair, at least one of the 1 shown components energy storage 22 and / or control electronics 21 with memory and wireless communication means, for example, a wireless communication link with a terminal 23 manufacture.

The 3 to 12 should symbolize, as by means of in 2 shown parallel kinematic different positions of the seat structure shown, or can be controlled by an electric motor.

The 13 . 14 show an alternative arrangement of the electric drives 4a . 4b on the pedestal 3 of the office chair.

For clarity, the show 3 to 14 none of the components, such as energy storage, control electronics, communication means, etc., which may have such an office chair.

Furthermore, the in 2 pictured office chair an energy storage 22 and a control electronics 21 with means for wireless communication with a terminal 23 as well as electric drives 5a . 5b on, in electrical operative connection with the control electronics 21 stand (electrical operative connection in 2 not shown). With one end is the lever 1.1 over a swivel joint 7 rotatably mounted with a pedestal 3 and with its other end over a swivel 7 rotatably mounted with one end of the lever 1.2 connected. The other end of the lever 1.2 is with the rotation axis 4a a rotary drive 5a , In particular, an electrically actuated rotary drive, rigidly connected, wherein the housing of the rotary drive 5a with the seat structure 6 of the chair is connected. The axes of rotation 4a . 4b and the axes of the swivel joints 7 are parallel to each other. Advantageously, the rotary drive 5a a motor-gearbox combination to convert a low engine torque at high speed into a high output torque at low speed of rotation. Particularly suitable for this purpose are transmissions with a high ratio, such as planetary gear, Excentergetriebe, worm gear, bevel gear or, most preferably, wobble gear.
To ensure inhibition in the non-actuated state of the rotary drive this may have a brake and / or the engine-transmission combination has a self-locking.
