Definitions
- the device for detecting and optionally correcting a posture of a person, wherein the device comprises a sitting or lying unit, at least one load-removing element and a measuring device.
- the patent application WO 03100741 A1 describes a device for detecting a posture of a person sitting on a chair, comprising sensors arranged in the seat surface and in the backrest of the chair and a tone generator. Depending on the pressure values on the backrest and the seat surface detected by means of the sensors, a sound signal is output by the tone generator.
- the patent application WO 0217752A1 describes a method and a device provided for detecting the sitting posture of a person. This also includes means for admonishing the person to a correct posture, in which case again the posture of the person is detected by a plurality of sensors arranged in the seat surface and in the backrest.
- the document KR20020025448 describes a chair having a plurality of sensors positioned in the seat and back of the chair, whereby the posture of the seated person is detected by these sensors.
- the invention discussed here has the task of measuring the posture of a person on a sitting or lying unit by means of a device, wherein the device can be attached to, for example, a chair without much effort.
- the measuring device for detecting a force and / or distortion state is arranged in the intersection between at least a part of the sitting or lying unit and the at least one load-removing element on and / or in the load-removing element, wherein based on measured values , which by the measuring device for detecting the force and / or Distortion condition are measured, the presence of the person on the sitting or lying unit and / or the posture of the person can be determined.
- the arrangement of sensors as units of the measuring device in the interface between the seat and, for example, the chair support of an office swivel chair is much simpler than the attachment of sensors to the seat of a chair.
- measuring devices may be additionally or exclusively arranged on and / or in load-bearing elements such as between the legs and rollers of an office chair.
- the invention further includes that the posture of a person sitting in a wheelchair is easily detected by placing measuring devices in the intersection between the seat and the frame of the wheelchair.
- the invention also includes the arrangement of measuring devices between the lying unit and the load-bearing element of a bed, such as a support of a bed, to detect the position of the person lying in bed. The latter also includes detection of whether the person is in bed.
- seating and lying units are also to be understood as units on which a person performs movements or remains in postures that differ from sitting or lying down.
- a seat unit may also include armrests or headrests, wherein the posture of a body part such as an arm or head with respect to the armrest or the headrest is determined. Any movement of the person or body part of the person causes a shift in the center of gravity of the person or the local center of gravity of the body part.
- a shift in the Focus causes a change in the forces, which is removed by the seat and reclining unit on the load-removing element. Consequently, the state of force and distortion is changed in the interface between the seat and couch unit and the load-removing member and / or the load-removing member in the entire load.
- a measurement of the state of force and / or distortion in the above-mentioned ranges proposed in the context of this invention is advantageous in that measuring devices can be easily mounted. The latter also includes the subsequent attachment of measuring devices to existing facilities.

- Distance measuring devices take place. It is also possible within the scope of this invention to measure, for example, local displacements, the force and distortion state being determined from these determined values.
- a possible, further variant of the device according to the invention is that an additional mechanical device for controlling the distortion state in the interface between the sitting or lying unit and the at least one load-removing element on and / or in the load-removing element is arranged.
- an additional mechanical device for controlling the state of distortion in the load-removing elements such as legs of a chair or at least parts of a frame of a wheelchair
- the posture of the person can be influenced. For example, by inclining the seat surface of an office chair or a wheelchair, the posture of the seated person can be changed. The attitude is influenced by a change of the sitting or lying unit.
- a first state of force and distortion is determined by the measuring device and an alarm signal is output upon deviation of the first force and distortion state from a second predetermined force and distortion state.
- the measuring devices are coupled to a unit, which determines the attitude of the person from the detected state of force and distortion. By optionally issuing an alarm signal, the person is asked to change the attitude.
- the unit with which the attitude of the person is determined on the basis of the force and / or distortion is, for example, a computer which is in communication with the measuring unit.
- the person sitting on the seat unit works with the computer.
- a further possibility for using the device according to the invention is that a first state of force and distortion is determined by the measuring device and, in the case of a deviation of the first force and distortion state from a second predetermined state of force and distortion, the posture of the person is modified by the additional mechanical device ,
- the mechanical device for changing the posture of the person are also attached.
- linear actuators such as pneumatic devices that cause a change in the attitude of the person for a longer period.
- devices which cause a continuous and / or oscillatory movement can be provided.
- the measuring devices are arranged in a region between the sitting and lying unit and the load-removing element, wherein the ablation or the Forwarding the forces must be ensured by the sitting and lying unit in the load-removing element.
- the mechanical device for controlling the state of distortion may comprise at least two linear drives or pneumatic pistons or any other device known to those skilled in the art, by means of which a movement of the sitting or lying unit in a substantially vertical direction and / or a tilting of these can be accomplished.
- the above-described arrangement of the mechanical device for control can take place in a preferred form, so that the frictional connection between the sitting and lying unit and the load-removing element is ensured.
- a current posture of the person and at least one deviating from the current posture posture is displayed on a screen.
- the posture of a seated person working on a computer it may be advantageous to display the measured posture and, by comparison, better posture on the screen of the computer.
- the person is animated by the graphic display to a correct attitude.
- movements can be displayed on the screen or positions taken by the person in further steps.
- the device according to the invention can be used so that the person is animated by an at least partial change of the measured force and distortion state and / or by an alarm signal and / or by an analysis of the posture on a screen to movements.
- the animation can be done by an at least partial change of the measured force and distortion state and / or by an alarm signal and / or by an analysis of the posture on a screen.
- all methods known to the person skilled in the art are included in order to communicate to the person the current posture as well as a different posture.
- this power supply can take place, for example, in the form of power through a mains connection or a rechargeable battery, which is attached to the device, for example.
