Definitions

  • the invention relates to a mattress according to the preamble of claim 1.
  • a mattress is e.g. B. known from DE 1259018.
  • a "foam body" in the sense of the preamble is a to a foam z.
  • B. a polyether foam, a flexible polyurethane foam or a latex foam existing cuboidal foam molding.
  • the stiffening surface extends over the entire area of the lying surface.
  • the lined-up stiffening slats forming the stiffening surface are connected to one another with the aid of cords, which each loop around these stiffening slats to form a slatted grate. Adaptation to the individual height of the mattress user or his other specific support needs is not possible.
  • the invention has for its object to design a mattress of the type under consideration such that the very different support needs of mattress users can be taken into account without making production more difficult or expensive. According to the invention, this object is achieved by the characterization of claim 1 mentioned features solved.
  • a prerequisite for extensive adaptation to individual needs is a radical restriction of the stiffening area to a section of the spine comprising several thoracic and / or lumbar vertebrae. Usually the stiffening surface supports multiple thoracic and lumbar vertebrae. In-house studies have shown that increased support in the area of the spine mentioned satisfies all essential support needs, unless specific spine anomalies are present.
  • stiffening slats which form the stiffening surface
  • the stiffening slats are positioned between the foam layers of the foam body according to the data of the previously measured body of the mattress user, before they are fixed by gluing the foam slices.
  • the distance of the stiffening surface from the vertical central plane of the mattress, as well as the width and strength of the stiffening surface are important adjustment variables. It ensures that the spine is supported in the critical area, but the pelvic and shoulder areas of the mattress user are in lamella-free, i.e. softer sections of the lying surface, where protruding parts of the body can be molded into the foam when the body is on its side.
  • the lifespan of a mattress designed according to claim 2 can be significantly extended by turning the bottom mattress side upwards and the foot-side mattress half towards the head end.
  • a second stiffening surface does not interfere with the concept, since the support effect that occurs in the much less stressed leg half of the mattress is hardly noticeable; because that supporting counterforce from the stiffening lamellae 12 is proportional to the load acting on them.
  • An embodiment of the mattress according to claim 3 is a good prerequisite for a further development according to claim 4, exemplary embodiment of FIGS. 3-5.
  • the adaptation to the body dimensions or to specific support needs can be carried out by the mattress user himself by using the Slat unit and thus the stiffening surface shifts in the longitudinal direction of the mattress.
  • the tabs of the textile bag are open at least on one side.
  • the foam layers of the foam body along the long edges of the mattress in the displacement area of the stiffening surfaces are also open, that is to say not glued.
  • the stiffening lamellae can be pulled out or pushed in axially as desired from the tabs, as is indicated in FIG. 7.
  • the two flat sides of the mattress can serve either as soft or harder lying surface without the overall concept of the support being changed.
  • a training with the features of claim 12 improves the drying ability of the mattress. This can be of particular importance both for the processing of decaying natural latex foams in poor environmental conditions to be expected, as well as for the earlier processing of synthetic cold foams with a somewhat longer drying time compared to warm foams.
  • the lying surface is formed by a foam body 10, which is covered by a cover 11, see Fig. 1 u. 3, is included.
  • Numerous stiffening lamellae 12 are arranged within the foam body 10 and, in the exemplary embodiments, are made of wood, preferably of ash wood.
  • the lined-up stiffening slats 12 run parallel to the lying surface and at right angles to the longitudinal direction of the mattress.
  • the Slats 12 are resilient to a limited extent and form at least one stiffening surface A in the composite. This is suitable for partially supporting the body of the mattress user and thereby reducing the body-related deformations in the foam.
  • the stiffening surface A adjoining lamella-free areas is arranged in the area of only one half of the mattress.
  • Fig. 1 u. 4 positioned from the vertical center plane a - a.
  • the support effect is limited to a section of the spine that includes several lumbar and / or thoracic vertebrae.
  • a stiffening surface B or A is also provided in the area of the other half of the mattress. Both stiffening surfaces A and B are arranged approximately symmetrically to the vertical center plane a - a. In the embodiment shown in FIG. 1 u.
  • the stiffening surfaces are each formed by a flat slat unit 14, in which a plurality of stiffening slats 12 are combined to form a structural unit by means of a textile pocket, preferably a cotton pocket.
  • the slats are received in the tabs of the pocket 17 and sewn there.
  • the lamella units 14 lie between two foam layers 10b and 10c of the foam body 10 which are glued together, where they have been positioned according to the individual support needs of the mattress user before the foam layers are glued.
  • one or both lamella units 14 can be displaced to a limited extent in the longitudinal direction of the mattress for individual adaptation in a non-bonded displacement area between the two foam layers 10b and 10c.
  • the displacement takes place by means of a belt 18.
  • This acts on a fabric edge 17 'of the pocket 17 and is led out of the mattress at the head and foot end.
  • Both slat units 14 of the mattress are connected to one another by straps 18 'and can therefore be moved together.
  • the displacement distance is marked with m.
  • the ends of the straps 18 are on the end faces of the cover 11 or on the underside of the foam body 10 in an overlap area, as shown in FIG. 4 u. 5 show, or on the underside of the mattress on the cover 11 in an overlap area by means of a Velcro fastener to one another and / or connected to the cover.
  • FIGS. 6 to 8 show a further embodiment which corresponds to the basic structure of FIGS. 1 and 2.
  • the tabs of the pocket 17 receiving the stiffening lamellae 12 are open on both sides.
  • the foam layers 10b and 10c of the foam body 10 are not glued to one another in the mouth region of the tabs. Therefore, the stiffening slats 12 located in the tabs can be inserted laterally into the mattress or pulled out of the mattress.
  • the supporting effect of the entire stiffening surface A or B can also be weakened.
  • 8 illustrates some possible changes with regard to the position and width of the stiffening surface A or B. These are denoted by r, s, t, u and v.
  • stiffening lamellae 12 in the tabs is easily detachable, as in the embodiment according to FIGS. 9 and 11, as can be seen from FIG. 10.
  • a prerequisite for the possibility of regrouping the stiffening slats 12 is a smaller number of stiffening slats 12 compared to the number of tabs of the pocket 17.
  • the stiffening slats 12 are not accommodated in the tabs of the pocket 17, but rather are arranged in individual cutouts 13 in the foam body 10. These can first be created by milling out the inside of a foam layer 10b or 10c and then gluing them together. In the case of foams with high crush resistance, the individual cutouts 13 can also be milled into the one-piece foam body 10. Less with foams The individual cutouts 13 can be produced in a corresponding shape by being foamed in order to withstand crushing as part of a mold for individual foam bodies 10. The stiffening lamellae 12 are arranged so that they can be pulled out in part of the cutouts 13.
  • the outputs of the cutouts 13 end freely in the longitudinal edges 10a of the foam body 10.
  • the number of individual cutouts 13 is greater than the number of stiffening slats 12 arranged in the foam body 10. This is a regrouping of the stiffening slats 12 and thus an adaptation of the Stiffening areas A or B to meet the individual support needs of the mattress user.
  • the lamella plane y-y lies at a distance from the horizontal center plane b-b of the foam body 10. This results in an optionally usable softer or harder lying surface by simply turning the mattress. 10 shows, the stiffening lamellae 12 are axially fixed in the individual cutouts 13.
  • the stiffening lamellae 12 which are approximately rectangular in cross section, can be used for better ventilation, thus avoiding fungal attack in the case of poor Environmental conditions and faster processing of slowly drying cold foams must be provided with several holes.
