  • WO 2019/179378 A, US 2016/255966 A and US 2020/0046136 A show solutions in which a mattress is variably controlled in order to optimize the lying position.
  • the object of the invention is therefore to provide a device and a method that is suitable for objectively enabling the selection of a mattress on the basis of the preferred lying habits of the target person and thus significantly improving the subjective feeling of lying.
  • This object is achieved by a method for the individual adaptation of a mattress to a target person, which has the following steps:
  • the mattress can be adapted to a specific person by selecting suitable support elements, these support elements being, for example, molded bodies made of foam which can be inserted into corresponding recesses in a foam mattress. These molded bodies are available in different degrees of hardness, so that the elasticity of the mattress is locally un differently and optimally adapted to the respective person through an appropriate selection of the molded body.
  • Mattresses of this type have been available for a long time, but it is difficult to carry out the adjustment process in such a way that an optimum is actually achieved in terms of the support function and the comfort of the person. In the context of the present invention, a measuring mattress is used to achieve this optimum, which makes the adjustment much easier.
  • the change in the measuring mattress does not take place by exchanging molded bodies, but rather by changing the pressure of the measuring support elements.
  • An important aspect within the scope of the invention is also the use of a camera by means of which the topography and the position of the target person, the deformation of the measuring mattress and the like can be recorded.
  • the invention makes it possible for the target person to ultimately assume the same optimal lying position on the mattress as he did before on the measuring mattress.
  • lying position means the position that the target person basically assumes, for example the supine position, side position or prone position.
  • Lying position means the alignment of the individual body parts to one another, which results from the distribution of the hardness of the mattress in the respective lying position, for example which lateral curvature the spine forms in the side position or the strength of the lordosis in the supine position.
  • the present invention makes it possible both to design the optimization process on the measuring mattress quickly, reliably and comprehensibly, and to obtain clear and easily implementable instructions for setting up the mattress.
  • the optimization process on the measuring mattress can be automated, for example by using image recognition processes to record the curvature of the target person's spine and changing the measuring support elements until the spine is arranged in a straight line in the sagittal plane of the body, which is generally the goal for a pleasant and health-beneficial lying position is considered. It is equally possible to have the adjustment of the measuring support elements carried out by a specialist who adjusts the optimal position based on experience and specialist knowledge. In addition, the subjective well-being of the target person can also be taken into account.
  • the pressures of the individual measuring support elements are primarily used as the recorded data, but also data that reflect the deformation of the measuring mattress.
  • the position and the geometrical properties of the target person on the measuring mattress are also recorded with the camera. This makes it possible, for example, to deduce a weight distribution based on the target person's geometric shape and thus improve the adaptation process. If a three-dimensional image of the target person is generated with the camera, then it is also possible to draw conclusions about the deformation of the measuring mattress in areas that are not directly visible on the basis of the recording of the lying person. Otherwise, the deformation of the mattress can in any case be determined in the areas next to the target person, for which a TOF camera is particularly well suited. This is a camera which, in addition to an optical image, can also obtain distance information based on the transit time of light signals (time of flight).
  • At least two cameras are particularly preferably provided, which are arranged on at least one camera arm which can be moved parallel to the longitudinal axis of the measuring mattress with the aid of a camera slide. This in particular makes it much easier to obtain a three-dimensional model of the target person, since it is possible to draw conclusions about the three-dimensional shape from the parallax.
  • a particularly advantageous variant of the method according to the invention provides that the deformation of the measuring mattress is calculated by measuring the topography of the target person located on the measuring mattress. This is usually combined with the creation of a three-dimensional model of the target person. For example, the shoulder width of the target person is determined here. If the target person is lying on their side, the deformation of the measuring mattress in the shoulder area can be calculated back from the distance between the upper shoulder and the level of the mattress.
  • a particularly simple variant of the present invention uses measuring support elements in the form of flexible hoses that assume a cylindrical shape under pressure.
  • the support elements are cylindrical foam bodies of different degrees of hardness.
  • the measuring mattress differs from the lying mattress essentially in that the flexible hoses are used instead of the foam bodies.
  • the support elements of the mattress can be designed in a simple embodiment as a foam cylinder.
  • a particularly comfortable solution is he suffices if the support elements of the mattress are formed out as foam profiles, which are also referred to as stamps. Due to the profiling, a smooth transition in the areas of different hardness is achieved in particular.
  • the target person on the measuring mattress in a first preferred lying position is topographically recorded, for example by means of an optical measuring device, preferably a 3D camera for example as a Time of Flight (ToF) camera.
  • an optical measuring device preferably a 3D camera for example as a Time of Flight (ToF) camera.
  • a 3D model of the target person is created in an evaluation computer, and essential parameters of the target person are determined, from which the relevant body areas such as head, shoulder, lordosis, pelvis, knee and foot are derived and furthermore, for example, the body size, the shoulder - and pelvic width as well as the body weight can be calculated.
  • the measured pressures in the adjustable measuring support elements are also evaluated computationally and, in a further embodiment variant, compared with the target person's parameters determined from the 3D model and an optimized pressure profile is set in the measuring mattress for the next optimization step.
  • the subjective perception of the comfort of the target person lying on the measuring mattress, the evaluation of the pressure distribution in the measuring support elements taking into account the 3D model of the target person enables an optimization process of adapting the individual properties of the measuring mattress to the needs and circumstances of the target person.

  • the air chambers 122 arranged in the measuring mattress 120 essentially correspond to support elements with the same or similar geometry, which are arranged in the individually adapted mattress. These support elements can have different strengths and thus different support forces, the type and arrangement of the support elements in a mattress individually adapted to the needs of the person 200 being simulated and optimized with the aid of the air chambers 122 in the measuring mattress 120.
