Definitions

  • the invention relates to a reclining system with a support device for a mattress placed loosely thereon, in which support elements in the form of fluid-containing hollow body elements, the wall of which is deformable, are arranged between the support device and the mattress at least in partial areas of the support surface of the support device, and in which Adjacent hollow body elements have a distance from one another.
  • the patent DE 34 34 641 C1 describes a support device for a mattress as compared to the patent DE 32 46 2212 C2 improved slatted frame, in which air tubes are used on the top parallel to some of the existing spring slats.
  • the purpose of combining some of the spring slats of the slatted frame with air hoses is to improve the support of a person resting on the mattress - referred to as user in the following text - compared to using a slatted frame without additionally arranging air hoses and thereby dispensing with elaborate mechanical adjustment devices can.
  • the published patent application DE 43 02 778 A1 describes a reclining system, which is referred to there as a reclining surface, in which the arrangement of a plurality of hoses filled with a variable amount of air, which are placed in the longitudinal direction of the reclining surface, is provided in a cavity formed by two slatted frames cover approximately 60% of the length of the bed surface in the middle. In the same cavity there is also an air reservoir in the foot area. Above the two slatted frames and a layer of elastic material, a hose filled with a variable amount of air is arranged transversely to the lying surface below the cervical vertebrae and the pelvic region of the user, on which a further layer of elastic material is placed, if necessary detachable from the lower area.
  • the invention is therefore based on the object of lying systems with commercially available support devices, in particular in the form of a slatted frame, but also in the form of e.g. by means of steel springs manufactured under mattress, or reclining systems with elastic support plates inserted into the frame, if necessary also after their purchase, with the help of support elements in the form of deformable hollow body elements containing a fluid, to be supplemented with relatively little effort so that while maintaining the prerequisite for one vertical air exchange in the reclining system, the body of the user is approximately optimally supported and the user has the possibility, by means of simple measures, of being able to fine-tune his or her body support, in particular in the area of his lumbar vertebrae.
  • hollow body elements with a low-stretch wall and with a longitudinal extension which is less than the length of the lying system are releasably placed on a commercially available support device at least below the lying area of the back of the user side by side in the system longitudinal direction and / or in the system transverse direction and that, as far as required for a support height compensation, on areas of the bearing surface which are not covered by hollow body elements
  • Support device further support elements in the form of plates made of elastic material are placed.
  • the concave lumbar region is supported approximately optimally by the fluid that accumulates there, regardless of the exact position of the user on the lying system, so that the muscles and back vertebrae associated with this region are braced with their intervertebral discs both in the back and in the lateral position of the User is largely prevented. Regeneration of the intervertebral discs during sleep is favored. This effect occurs regardless of whether the hollow body elements are placed in the system longitudinal direction or in the system transverse direction.
  • the hollow body elements are all designed and detachable, for.
  • air-permeable plates made of elastic material are placed on areas of the support surface of the support device that are not covered by hollow body elements.
  • the additional support of such panels is not necessary or is only necessary in partial areas of the lying system surface if hollow body elements arranged in the longitudinal direction of the system have a small, e.g. have an average support height of only approx. 10 mm.
  • the elastic, air-permeable material of the plates can, for. B. latex or foam or a latexed fiber composite, wherein the plate thickness is selected according to the support task assigned to them.
  • the wall of the hollow body are available as a hose without a seam formed rubber films or z. B. at the edges welded or glued plastic films each with or without fiber reinforcement.
  • an additional covering of the hollow body elements for. B. with a low-stretch textile fabric into consideration if the fluid-tight wall of the elements themselves is not sufficiently low-stretch.
  • the fluid in the hollow body elements can e.g. B. air, a liquid, e.g. B. water or oil, or a gel.
  • hoses filled with a liquid or a gel which are glued flat and fluid-tight at their two ends, vulcanized and / or pressed together by means of a device are, e.g. B. filled with water or gel, simple rubber hoses with a diameter of z. B. about 60 to 125 mm and a filling amount in the range of about 25 to 75% of the maximum possible filling amount with flat closed hose ends.
  • the user When such hoses are placed on a support device consisting of a slatted frame, the user has the possibility of adapting the active support length and fluid filling quantity of all or some selected hoses to individual requirements by the user moving the ends of the hoses downward in the area of a gap between two adjacent slats can sag or alternatively one end closed by vulcanization or gluing down under the hose.
  • the area of the support surface of the support device assigned to the legs can, if required, either be covered by one or more plates or by additional hoses of corresponding length.
  • hoses with a length continuously from the shoulder area of the user to the foot end of the lying system, it then being expedient to limit the support height of the hoses in the lying area of the user's calves with the help of one attached to each of the hoses sliding bandage.
  • a particularly simple, yet advantageously effective and easily adaptable to the size of the upper body of the user of hoses arranged in the system longitudinal direction results when hoses with a length of approx. 500 mm and a fluid filling level of approx. 25% in the lying area of the back of the user Support device are placed, whereby the additional placement of plates can usually be dispensed with.
  • Hoses placed in the transverse direction of the system have a longitudinal extent in the generally used lying systems which corresponds to the width of the lying system. So you are often z. B. about 1.0 m long. Comparative studies have shown that a hose diameter in the range of approximately 90 to 125 mm and a fluid filling level of 60% have been advantageous.
  • Such hoses placed in the transverse direction of the system can, if desired, cover the entire surface of the support device and can be matched by the user in a very simple manner to individual requirements with regard to their fluid displacement taking place under load, that is to say with regard to their adaptation behavior when supporting the body parts assigned to them.
  • This is done by hanging or underlaying z. B. about 20 mm thick supplementary plates z. B. made of elastic material or by attaching bandages in the area of the two rope end zones of a hose.
  • This makes fluid displacement in the lying area more difficult and the sinking depth of the relevant part of the body is reduced.
  • For such a measure come into consideration for. B. in the system transverse direction hoses below the lumbar region when the user has a pronounced, so-called hollow cross.
  • hoses of different diameters it is also possible, if necessary, to take into account special requirements of a user.
  • Combinations of e.g. B. tubes arranged in the system longitudinal direction under the lying area of the back and buttocks with tubes placed in the system transverse direction in the lying area of the shoulder and the legs of the user can be helpful and useful. Since the hoses are releasably placed on the support device, there is, if necessary, the possibility, regardless of the type of support device, to generally change the hose by exchanging the hose or by changing the degree of fluid filling and thus the relative support heights.
  • Figure 2 shows the basic outline of the body contour of a user of the same body length KL and figure, but in the supine position.
  • the concave problem zone of the lumbar vertebra area L is again recognizable by the tangent T applied to the underside of the outline course.
  • the area W is also identified for the zone of the calves.
  • FIG. 3 shows the longitudinal section of a lying system with the length LSL, the head end KE and the foot end FE.
  • a frame 1 with a supporting device designed as a slatted frame can be seen 2 and the mattress 3 and above the support device 2 and below the mattress 3 the support elements 4d, 5 and 6 visible in the central longitudinal section of the lying system.
  • the support element 4d is the middle one of seven next to each other with the length HL in the system longitudinal direction placed, fluid-containing hoses in the example shown placed below the back of the user indicated in Figures 1 and 2.
  • the support element 5 placed towards the head end KE is a plate made of elastic material, e.g. B. made of perforated latex.
  • the rest of the area of the support surface of the support device 2 covering support element 6 is also a plate made of elastic material, for. B. from a latexed fiber composite, in the example shown with a lower support height than the support element 5 and with a recess 7, which takes into account the area of the calf W of the user.
  • FIG. 4 shows the top view of the support elements of the embodiment of a lying system with the width LSB shown in FIG. 3.
  • the seven hoses 4a, 4b, 4c, 4d, 4e, 4f and 4g which are placed next to one another in the longitudinal direction of the system and can be seen, as well as the support elements 5 and 6 with the recess 7 analogous to the illustration in FIG. 3, remain between adjacent hoses a gap s to ensure the vertical air exchange in the lying system. If a small amount of fluid is selected in the hoses, the hoses 4a and 4g and the plates 5 and / or 6 may be dispensed with.
  • FIG. 5 shows the top view of an alternative arrangement of support elements to that in FIG. 4, in which hoses 8a, 8b, 8c, 8d and 8e are placed in the transverse direction of the system from the shoulder area S to approximately the knees of the user shown in FIGS. 1 and 2.
  • the tube 8c is assigned to the lumbar region L. and possibly contains a slightly larger amount of fluid than the other hoses shown, or in the region of its two lateral end zones, if necessary, supplementary plates 9 are enclosed for the purpose of fluid displacement or alternatively bandages 10 are attached.
  • bandages can e.g. B. be made of a plastic and consist of two interconnectable parts.

  • a space a is indicated between the plates 12 and 13, which takes into account the area of the calves W of the user.
  • FIG. 6 shows a longitudinal section of a hollow body element made of a tube and containing the fluid 15, the tube wall in the example shown being composed of the fluid-tight wall 16 and a low-stretch textile covering 17.
  • the wall 16 is closed at one end by means of the device 18 and at the other end 19 by means of vulcanization or gluing.

  • FIG. 8 shows the top view of a hollow body element made of a hose with the device 18. It can be seen that the width b1 of the hose ends is greater than the width b2, which is why there is a gap between two adjacent hollow body elements remains, which corresponds at least to the difference between the dimensions b1 and b2.
