Definitions

  • the invention relates to a mattress with a first foam area and a second foam area, in this case the second foam area is arranged at least in regions in a receptacle of the first foam area.
  • a first foam area serves as a support.
  • this foam area there is a receptacle in the area of the lying area from the shoulders to the buttocks in which a second foam area is used.
  • the second foam area should have a higher quality than the first.
  • the object of the invention is to design a mattress of the type mentioned in such a way that it provides optimal support for a user when lying down.
  • the mattress should be inexpensive to manufacture.
  • This is done according to the invention in that the second foam area is attached to the first foam area in the receptacle without adhesive, in that the second Foam area in plan view of the lying surface of the mattress extends transversely to the longitudinal direction of the mattress and that the material of one of the foam areas compared to the material of the other area after its loading has a different resetting behavior of its material shows in particular a slow resetting behavior.
  • Special shape cuts make it possible to connect the two foam areas to one another without adhesive, which is important on the one hand with regard to production, and on the other hand that no harmful adhesives, solvents or the like are stored in the mattress or in particular in the foam area. Due to the foam area extending transversely to the lying surface of the mattress, it is also possible to optimally design a certain zone for the user, so that, for example, the shoulder or the back is optimally supported. In a special embodiment of the invention, the second foam area is detachably fastened in the first foam area.
  • the shaped cuts are made in such a way that the two foam areas easily interlock, are securely held and can be removed if necessary, for example to replace the second foam area with a certain hardness by another with a different hardness. This is important if the mattress is to be optimally aligned for a specific user.
  • the second foam area extends from one long side of the mattress to the other, so that it is ensured in this way that a zone on the human body particularly comes into contact with this second foam area, even if the user should turn.
  • the releasable fastening of the second foam area is thereby increased. It is advisable to build the second foam area out of the material with the slow return behavior and to place it on the part of the mattress where the shoulder zones of a mattress user come to rest.
  • the Special foam that shows a slow recovery behavior provides an optimal pressure distribution for this sensitive area, so that even when the body is turned, the shoulder area of the user remains on this special second foam area, while the rest of the body lies on the first foam area, and in particular optimal support and restoring force, especially in the lumbar region, guaranteed.
  • the first foam area consists of a material that has a high restoring force after loading, which in particular ensures a safe restoration of the material in the lumbar region of a user. This material has a particularly high resilience, so that the lumbar region is safely supported by this material.
  • the first foam area with the second foam area located in the receptacle is mat-like and covers a spring mattress.
  • This measure also allows a spring mattress in the shoulder zones of the mattress user to use the foam that has a weak, slow resilience, while the rest of the mattress part shows a high resilience, so that in addition to the spring mattress, which has its special advantages, the additional advantages of a foam mattress are added. Due to the mat-like cover, which is expediently provided on both sides of the spring mattress, the manufacture of the mattress is not significantly more expensive. It should be noted here that, of course, barrel spring mattresses can also be used instead of a conventional innerspring mattress.
  • undercuts are provided in the receptacle, behind which protrusions of the second foam area engage. These shaped cuts ensure secure attachment. It is recommended that the undercuts with the receptacle and the projections - seen in the transverse direction of the mattress - have a T-shaped shape so that the second material areas can be pushed into the receptacle of the first material area and there against vertical pulling out by the Undercuts and protrusions is held; due to the frictional force between the second foam area and the first, when the mattress is loaded, these two parts are fixed to one another against horizontal pulling out.
  • openings are provided in the mattress through the first foam area, which on the one hand serve to ventilate the mattress and on the other hand change the spring action of the mattress in this area, thereby providing an even more secure and optimal adaptation for the human body is.
  • the openings are connected to a bed surface of the mattress via slots, in order to be able to manufacture these openings more easily and to be able to incorporate special reinforcing means into these openings.
  • transverse openings are provided in the lumbar region of the mattress, which receive reinforcement wedges in the manner of inserts. This insert creates an insert element between the shoulder area and the hip area, the reinforcement wedge being designed as a so-called lordosis wedge.
  • the hardness of the wedge can be chosen differently depending on the shape of the lumbar spine. In the case of a pronounced lumbar spine curvature (hollow cross), a harder part is selected in order to achieve a correspondingly high support pressure.
  • the breakthroughs have a diameter that corresponds to approximately half the thickness of the mattress.
  • the reinforcement wedges have a cross section which shows a hand-like shape. This measure ensures that the fingers of the wedges are securely supported on the wall of the openings. In addition, air-like channels are created around the reinforcement wedge, which significantly increase the ventilation of the mattress.
  • a plurality of depressions which run parallel to one another and run transversely to the longitudinal direction of the mattress are provided. These depressions in the central zone of the mattress ensure that the hip area sinks in deep compared to the sinking depth of a full block. This results in a better pressure distribution of the body because, due to the natural double S-shape of the spine, a deep sinking of the hips reduces the pressure peaks in this area, with the depressions advantageously having a different penetration depth in the first foam area.
  • the middle of the parallel depressions show a greater depth of penetration than the lateral ones, so that, as already mentioned, the hip area can sink in relatively deep.
  • adjacent channels are provided between the hip areas of the two lying surfaces of a mattress in the middle transverse to the longitudinal direction. These channels reduce the strength of the spring action.
  • this area of the mattress surfaces is particularly well ventilated, because on the one hand there are the depressions on both lying sides of the mattress and on the other hand the two openings for the reinforcement parts and finally the channels.
  • the mattress 10 according to FIG. 1 consists of a first foam area 11, which forms the actual core of the mattress.
  • the foam area 11 has approximately a cuboid shape.
  • the foam area has the lying surface 12 on its upper side and the lying surface 13 on its lower side.
  • the lying surface 12 is provided with a receptacle 19, which extends transversely to the longitudinal direction of the mattress from one long side 23 to the other long side 24 of the mattress.
  • This receptacle 19 is provided with undercuts 20.
  • the receptacle 19 is filled by the second foam area 22. This engages with rib-like projections 21 in the undercuts 20, so that the second foam area 22 in the first foam area 11 can be held solvent-free on the mattress. A bracket is only guaranteed by the two shaped cuts.
  • the foam area 22 is so equipped that it does not protrude above the lying surface 12, but lies in the plane of the mattress.
  • the second lying area 22 is arranged where the shoulder zone of a user comes to lie later.
  • the two foam areas have a different spring behavior
  • the material of the first foam area is made of an elastic material that has a high restoring force
  • the second foam area 22 has a special foam with slow resetting behavior. This means that with a load in the first foam area, when the load is lifted, the material immediately springs back; in the second foam area, however, this foam area slowly changes its shape after a load, until it has finally returned to its original shape.
  • openings 17 are provided transversely to the longitudinal direction of the mattress. These openings 17, which extend transversely between the two longitudinal sides 23 and 24, are connected via a slot 18 to the upper lying surface 12 or the lower lying surface 13.
  • the mattress 10 again has a cuboid shape.
  • the main core consists of the first foam area 11.
  • Receptacles 19 are transverse in this foam area incorporated into the longitudinal direction of the mattress, in which a second foam area 22 is accommodated.
  • a plurality of second foam areas 22 are provided.
  • a central zone 15 is provided between the two shoulder zones on the lying surface 12 or 13. This central zone 15 receives the rest of the back of a person.
  • This central zone 15, as shown in FIG. 2, is delimited in side view by openings 17.
  • these openings 17 take the reinforcing parts 25, so-called lordosis wedges.
  • the reinforcing parts 25 nestle against the inner wall of the opening 17. They can be selected to be different hard depending on the strain on a person or the shape of the lumbar spine.
  • a harder wedge is chosen in order to correspondingly achieve a high support pressure.
  • these reinforcing wedges have a hand shape in cross section, as a result of this, air channels can be formed around the reinforcing parts, through which air can be transported, for example, for cooling purposes.
  • channels 26 lying next to one another are provided, which are seen exactly in the side view of the mattress and are arranged centrally between the upper and lower lying surfaces 12, 13.
  • depressions 27 are arranged on the two lying surfaces 12, 13. As can be seen from FIG. 2, these depressions are introduced into the foam area 11 to different degrees.
  • the middle recess in the foam area has a larger recess than the two outer ones.
  • the channels 26 and the openings 17 with the reinforcing parts 25 a relatively large sinking is ensured as desired, in comparison to the sinking depth at a full block, if the foam area 11 were completely filled.
  • These depressions, channels and breakthroughs result in an optimal pressure distribution for the resting body, since due to the natural double S-shape of the spine, a deep sinking of the hips reduces the pressure peaks.
  • the openings for the reinforcing parts 25 are also equipped with slots 18. This measure makes it easy to install these reinforcement parts 25. As can be seen further from FIG.
  • depressions 27 are also provided in the head and foot part, that is to say at the upper and lower end of the mattress 10, both on the upper and on the lower lying surface. These depressions serve on the one hand to hold the mattress when machining, and on the other hand the sinking depth of the head can also be changed in these areas.
  • the two shoulder zones 14 and 16 between which the central zone could also have a different hardness.
  • the shoulder zone 16 would have a different purpose, for example in order to be able to support the feet or the lower legs and knees differently.
  • the thickness of the second foam areas 22 corresponds to approximately 1/4 the thickness of the first foam area 11.
  • the foam area 11 is presented as a mat.
  • the mat is provided with receptacles 19 into which the second foam area 22 can be inserted in a solvent-free manner.
  • These mats 28 have the task of covering a spring mattress and thus allow the advantages of the different spring action of the individual areas to be brought to full effect even with a spring mattress.
  • the structure of this mat is similar to the mattress in the previous embodiments.
  • the illustrated embodiments are only examples of implementations of the invention, which is not restricted to this. On the contrary, there are still many changes possible.
  • the recordings did not need to be T-shaped, as shown, they could also be dovetail-shaped.
  • the second foam areas could also engage behind individual areas of the receptacle via individual projections, which are designed like mushrooms, and thus be securely held on the first foam area. There is then no linear definition, but a specific definition of the two foam areas. In order to ensure full air circulation, the long sides of a finished mattress would be provided with air-permeable layers.
