  • Impairments such as back pain, intervertebral disc problems, Sleep disorders, rheumatic diseases, muscle and joint pain such as arthrosis, circulatory disorders, tension, Postural defects such as scoliosis, Scheuermann, ankylosing spondylitis, Etc.
  • the spring elements which act independently of one another, additionally offer the Advantage, a lying system according to the invention exactly on the anatomy of a person to be able to vote. This is especially true for people over the body length pronounced uneven weight distribution is an advantage.
  • Such Anatomy runs the risk of having body areas with strong weight concentration sink too much in relation to other areas in the bed construction, causing the body is in the wrong resting position. Through a continuous This can increase the spring force of the spring elements in these areas negative appearance can be corrected. The correction is made via the Adaptation of a variety of spring elements, so that one continues Pressure-free storage of the body is guaranteed.
  • the individual Adaptation of the lying system to different circumstances possible thus the optimization of lying comfort and also extends the Field of application of the invention considerably.
  • Another advantage results from the surprisingly simple structure of the Lying system. So the invention comes without liquid media, pumps, motors or electrical components. This makes it easier to set up and dismantle one piece of furniture equipped according to the invention and thus increases its mobility. By dispensing with complex technology, the lying system can comparatively low cost, which makes the circle potential customer significantly increased.

  • a material with a low coefficient of friction the friction between piston and cylinder can be considerably increased reduce, so that the smoothness of the lying system according to the invention is improved.
  • the use of a material entails relatively soft surface to reduce the Noise caused by the piston and cylinder colliding goes back.
  • a suitable material is, for example, a polyester fleece proven.
  • the cylinders have a diameter between 15 and 30 mm and a length between 150 and 250 mm. This Dimensions give the lying system sufficient stability itself if natural materials such as wood-based materials are used.
  • the piston of the cylinder-piston unit preferably has a length between 150 and 250 mm. This ensures that a sufficiently deep one Sinking of individual parts of the body takes place. It proves to be advantageous if the pistons are articulated to the crossbars. This will excluded that there was an asymmetrical load on the crossbars tilting of the pistons inside the cylinders.
  • Another embodiment of the invention provides that individual Spring elements within a longitudinal frame have a different spring force have. This makes an adjustment and thus optimization of the lying system to different stress cases. Because a weight concentration can be expected especially in the abdominal and pelvic area of people advantageously spring elements in this area an increased spring force against spring elements in the end areas.
  • the Spring elements have a spring force between 2.0 and 6.0 kg, with springs with a spring force between 3.5 and 4.0 kg is regarded as particularly favorable become.
  • the spring force adjacent spring elements in steps of 0.5 kg to 1.0 kg changed.
  • the compression springs can be used to prevent radiation be plastic coated.
  • the spring force increases progressively during exercise. As the immersion depth of the body increases One finds that the spring force applied to him increases disproportionately automatic adjustment of the lying system to different load cases instead, this prevents body parts with large Weight concentration drop too low, resulting in an incorrect resting position would lead.
  • Another embodiment of the invention has the holes penetrating bar. This ensures that all the springs of the Find a smooth replacement bearing at exactly predetermined position, regardless of how deep the holes are drilled in the longitudinal frame have been.
  • Another embodiment of the invention claims as rigid as possible Crossbars.
  • the high inherent rigidity of the crossbars leads to a quieter one Rest position, which promotes relaxation of the muscles.
  • the distance between the individual spring elements in a longitudinal frame is advantageously less than 10 cm. This creates a sufficient number Sections to trace the body contour of the patient as precisely as possible and the body weight of the resting person evenly towards the lying system to distribute.
  • a mattress according to the invention results from its multi-part core, which is composed of individual element strips.
  • the Movability of the individual element strips in relation to neighboring ones Element strips in the vertical direction allow for the greatest possible adjustment the mattress to the respective body contour.
