Definitions

  • the invention relates to a method for using a cushion for a chair, preferably an office, work or leisure chair, as well as such a cushion, a chair with such a cushion and a computer program product.
  • the cushion has a cushion element which is movable with at least one degree of freedom assigned to the cushion element.
  • the mobility should be given in particular as permanent mobility during the use of the pillow, that is, when a person is sitting or standing on it. This can imply that the mobility is such that for a longer period of use of the cushion, movements take place in a further direction than that originally taken, so that, in particular, a return or almost return to the original state can take place in the long term.
  • the mobility should preferably allow such small movements that it cannot be consciously felt by a normal person sitting or standing on the pillow, but is noticed subliminally.
  • Cushions that cause such subliminal movements are also known as phoronomic cushions, especially when used in chairs.
  • Such chairs are in the US 2011/269601 A1 , the US 7,931,334 B1 , the DE 197 50 441 A1 and the US 2016/242562 A1 disclosed.
  • a first chair element on which the cushion element can be placed or in which the cushion element can be integrated can be any component of the chair. However, it is preferably a first chair element arranged either in the back or on, on or in the seat of the chair. In this way, the subliminally stimulated movements can strengthen the back and lumbar muscles of the person sitting on the chair and lastingly work out.
  • a chair element with a staggering seat pad is, for example, from WO 2016/067217 A1 of the present applicant III SOLUTIONS GMBH, Rebmattli 9a, 6340 Baar, Switzerland.
  • the office, work and leisure chair described therein comprises a cushion with a plurality of deformable (deformable) air chambers (for example four air chambers) under the seat cover, the plurality of deformable air chambers being connected to one another and on an elastically deformable (deformable) hollow body rests. Every time you sit down on the chair, this hollow body serves as a pump to inflate the air chambers. Every time you get up from the chair, the hollow body fills again with air due to its elastic expansion.
  • the seat pad When the person shifts their weight in the chair, the seat pad stumbles imperceptibly, the person makes a countermovement, the seat pad stumbles back again, etc.
  • the same present applicant describes an office, work and leisure chair with a staggering seat cover.
  • the seat pad rests via a cover plate on several spring elements which are mounted displaceably in the direction towards the edge region of the bottom plate of the seat pad. When the weight is shifted on the seat support, the spring elements move back and forth.
  • the WO 2016/067217 A1 suggests equipping the chair with a so-called garage into which a smartphone can be inserted.
  • Such smartphones have sensors. These sensors can detect how the garage is moving due to the swaying motion of the seat cover. First, a series of measured values is recorded. The measured values are then sent using an app (application) analyzed on the smartphone.
  • a cushion in particular for an office, work or leisure chair, which comprises a cushion element that is movable with at least one assigned degree of freedom, in such a way that it makes it easier for the person is to find the optimal settings for a chair with such a cushion and / or to actively support the training process in some other way and / or to provide further possibilities for using such a cushion.
  • the task also includes providing a corresponding cushion and chair and a corresponding computer program product with a program code.
  • the object is achieved by a method with the features of claim 1, by a cushion with the features of claim 9, a chair with the features of claim 13 and by a computer program product with the features of claim 14.
  • At least one sensor built into the cushion is used to detect the position or the change in position to at least one cushion element with regard to at least one degree of freedom assigned to it, the sensor being coupled to an interface for wireless output of measured values.
  • the at least one sensor records measured values and transmits at least some of the recorded measured values to a device outside the cushion element via the interface, the device receiving and evaluating the measured values and an output signal issues.
  • the cushion has a built-in sensor, it can have a defined position, for example in relation to the other components and elements of a chair on which the cushion is placed or in which the cushion is integrated. In this way, the position and also a change in position of the cushion element can be recorded particularly precisely.
  • the measured values obtained can also be made available immediately, which enables a quick evaluation of the measured values within or by the device which is located outside the cushion.
  • the output signal can give the person sitting or standing on the cushion a corresponding feedback.
  • the method according to the invention is used in such a chair with a cushion of the type described, in which the at least one first chair element comprises a seat support which is supported in a wobbly manner, with at least two sensors detecting the position or change in position of two different areas of the seat support and providing corresponding measured values send the device.
  • the two sensors take into account the fact that there are two degrees of freedom.
  • the muscles in the lumbar region in particular are strengthened when the seat cushion is staggered.
  • the invention provides that the method is used with a cushion on or in a chair elastically deformable (also deformable) hollow body rests on it, which acts as a pump for inflating the air chambers every time you sit down on the pillow and fills with air again every time you stand up from the pillow as a result of its elastic expansion.
  • a pump hose with a one-way valve is also preferably provided from the hollow body into at least one of the air chambers, for re-pumping any leakage losses.
  • Connecting hoses between The air chambers are equipped with valves that can be opened or closed mechanically, hydraulically, pneumatically or electrically so that the swaying path of the seat plate and the damping of the swaying movement can also be varied here.
  • the same is used in a chair on which the cushion is placed, which has at least one adjustment device with which at least one of the first chair elements and at least one of the degrees of freedom assigned to it can be adjusted
  • the output signal accordingly gives an instruction to actuate a device from the at least one device for setting.
  • the measured values are used to correct, if not even perfect, the setting of a chair with such a cushion element with respect to at least one of the first chair elements.
  • a control signal is output as the output signal. In other words, not only is information reproduced, but the device immediately effects the next step.
  • the device outside the pillow is (or at least comprises) a data processing device, in particular a computer, a smartphone, a tablet computer.
  • the data processing device has an output device, and the control signal that may be present controls it. (Even in embodiments in which no control signal is output, the device can have the properties mentioned as a data processing device - computer, smartphone, tablet computer or the like.)
  • the sensor continuously records measured values, these via the Interface is continuously transmitted to the data processing device and these are continuously received by the latter and an output made on the output device varies over time as a function of the measured values.
  • an optical display on a screen as an output device can directly reproduce the movement of the cushion element.
  • a corresponding two-dimensional representation can be given on a screen.
  • an arrow on the screen or the cursor can be controlled by moving the person sitting on the chair with respect to the seat cover. In this way there is a special incentive for the person sitting on the chair to move around in the chair in a certain way. (The movements are then no longer subliminal, but conscious.)
  • control signal is used to control a user input for a program, in particular to control a cursor and / or as an input signal for an application, a game or the like.
  • the body movements of a person sitting or standing on the cushion element can thus directly initiate program inputs.
  • the avatar of a player in a computer game can be controlled in this way, which creates interesting and entertaining new input options.
  • the movement pattern detected by the sensor has also proven to be highly individual.
  • This movement pattern can thus also be used in the sense of a digital “fingerprint” in order to identify a user of the seat cushion.
  • Such an identification can already take place after recording the movement pattern for about 10 seconds to 20 seconds.
  • This fingerprint can be recorded and verified both for a user sitting on the cushion element and for a user standing on it. This can be used, for example, to recommend specific seat settings for an identified user, which means that repeated optimization of the seat setting based on the movement pattern can be dispensed with.
  • the output signal can generally be or at least include an optical, acoustic or haptically detectable output signal that can be detected by a person.
  • the device makes outputs outside of the pillow with which a person sitting or standing on the pillow is induced to move on the pillow, which are preferably predetermined movements.

  • the cushion comprises a pneumatic wobble cushion, which has a plurality of deformable air chambers connected to one another and rests on an elastically deformable hollow body, which acts as a pump for inflating the air chambers every time you sit down on the cushion and which moves away from you every time you stand up Fills the cushion with air again as a result of its elastic expansion.
  • the cushion is preferably designed such that when the cushion element is loaded with a weight over the complete range of at least 40 to 100 kg for the weight and preferably from 30 to 120 kg for the weight, it records measured values and outputs them wirelessly.
  • the pillow should be able to serve both as a seat cushion and should also be able to be used when the user is standing on the cushion. The latter makes sense if the user is standing in front of a standing desk on which his computer is located. When standing on the pillow, the total weight of the user is applied to the pillow (for example 80 kg), when sitting with only about half (then 40 kg).
  • the cushion element must be suitably stable and, in particular, be designed in such a way that the degree of freedom for movement is given in the entire weight range.
