According to the invention, the mattress core (13) has multiple vibration cavities (15), each of which is designed as a cavity or a channel for introducing a vibration device in the form of a vibration rod and which are arranged in a region below the lying surface (2) so as to run parallel to one another in a transverse direction of the lying surface (2), wherein when the mattress (1) is used as intended, the lower limbs of a mattress (1) user lying in the supine position on the lying surface (2) are located in said region such that the vibration rod can be introduced into a vibration cavity (15) located below the center of the calves of the user in order to adapt the position of the vibration rod to the individual body dimensions of the user and the position of the user lying on the lying surface.

Description

The invention relates to a mattress with a lying surface for a user, comprising a foam-like, elastic mattress core and a spacer fabric arranged on the mattress core, the mattress core having a vibration cavity which is provided and designed in such a way that it contains a vibration device , which comprises an imbalance mass driven by an electric motor, can be arranged to generate vibrations in the mattress.

Healthy people spend around a third of their lives sleeping. There is a large number of different mattresses available on the market that ensure a healthy sleep thanks to their excellent support for the spine, pelvis and shoulders. Other mattresses with additional functions, such as massage and / or magnetic field therapies, are also available. In DE 30 14 739 A1 a mattress is proposed which has cavities to increase its elastic deformability. The mattress comprises two superposed, loosely superposed layers, between which cavities are arranged. The cavities are formed by semicircular recesses which are designed to correspond to one another in the layers lying on top of one another and which form round, transverse, channel-like cavities. The cavities extend over the entire width of the mattress and are Almost the entire length of the mattress, with the exception of a central area, is arranged.

For bedridden people who spend even more time in bed, there is a range of different mattresses available that can be used in nursing homes, nursing homes or hospitals. Due to the special situation of the affected patients, such mattresses have to perform different tasks and be designed differently than mattresses for healthy people. In particular, so-called decubitus or anti-decubitus mattresses are available to avoid the negative consequences of permanently lying immobile persons, which by reducing the maximum contact pressure by means of a special structure, a special material selection, a larger contact surface or a temporal alternating pressure system for the prophylaxis or therapy of decubitus ulcers be used. The parts of the patient's body are temporarily stressed and relieved.

Furthermore, reclining furniture and beds are known in which vibrations are used for reasons of well-being, comfort, massage or therapeutic purposes. For example, DE 103 04 494 A1 describes a treatment couch with a vibration device with motor-driven eccentric masses. DE 10 2006 010 416 A1 relates to a vibration relaxation couch with vibration motors for the head, back, legs and feet. DE 10 2008 032 232 A1 discloses a treatment couch with a vibration device with an eccentric motor with an eccentric mass which rotates in one plane and which is arranged in the area of the pelvis. From DE 10 2015 121 161 A1 a massage system with a massage actuator acting on a mattress is known. DE 20 020 607 U1 relates to a treatment bed with vibration generators and EP 0 267 546 A2 a treatment bed with a vibration device with an eccentric motor. EP 1 688 119 A1 describes a piece of furniture with vibration plates and EP 2 877 059 B1 a slatted frame with Vibrationseinrich device.

Embodiments of mattresses have also been proposed in which the device for generating the vibration is integrated into the mattress. DE 195 16 880 A1 discloses a therapy mattress with a membrane and a vibration generator that acts on the thigh, and DE 20 2012 102 514 U1 describes a mattress with a vibration system

In addition, it is known to use a layer of a so-called spacer fabric in mattresses to improve the Liegekom forts and in particular to avoid bedsores and decubitus. A three-dimensional knitted spacer fabric has an upper and lower side, each consisting of a network, between the upper and lower side approximately perpendicular or at an angle to the networks of directed resilient pressure-elastic spacer threads that extend the upper and lower side at a distance hold to each other. The elasticity is comparable to that of conventional foam. A knitted spacer is a three-dimensional textile in which two fabrics are joined by connecting elements that maintain a spacing. In general, spacer fabrics belong to the knitted or knitted fabric category. They are very light, dimensionally stable, crease-proof, point-elastic, adaptable, breathable and climate-regulating, offer a high level of pressure relief and wick away moisture quickly. They can also be antibacterial and prevent mite and mold infestation. Depending on the type of use, the outer layers consist of two identical or different textiles. They are held together by the spacer threads, so-called pile threads, at the desired distance (between 2 mm and 60 mm). The spacer threads are usually made of polyester. Such knitted spacer fabrics for mattresses or corresponding mattresses with knitted spacer fabrics are described, for example, in the following documents: DE 10 2004 056 056 A1, DE 10 2005 009 329 A1, DE 10 2009 013 253 Al, DE 20 2016 007 277 Ul, DE 20 2018 105 647 Ul, DE 20 2019 100 496 Ul and WO 2006/053775 Al.

A mattress with both a spacer fabric and an integrated vibration device with two vibration units each with an eccentric motor in the chest support area for releasing the mucus in the airways was proposed in DE 10 2015 110 901 A1. However, this mattress known from the prior art has some disadvantages. On the one hand, the outlay on equipment due to the two vibration units is high and prevents extensive use because, in particular, the cost bearers of such mattresses, for example health insurance companies, hospitals, old people's and nursing homes, are known to limit their expenses as much as possible. Furthermore, this mattress is relatively unsuitable for treating the entire body with vibrations because the vibrations are concentrated on the upper body, in particular the chest area, whereas almost no vibrations are introduced into the legs. In contrast, the user of the mattress feels relatively strong vibrations in the head, which is perceived as uncomfortable. Another disadvantage is that the introduction of vibrations into the body of the mattress user cannot be adjusted to his or her individual body dimensions and lying position. Finally, in the event of a malfunction or for maintenance of a vibration unit, it is necessary to separate the layers of the mattress that are glued to one another, which is at least costly and generally not possible in a non-destructive manner. Due to the use of a knitted spacer fabric, the mattress is basically suitable for counteracting bedsores or decubitus, but it is not optimally designed in this regard. Proceeding from this prior art, the present invention is based on the object of creating a mattress which requires less outlay in terms of equipment for generating vibrations and which can therefore be produced more cost-effectively. Furthermore, it should be suitable for treating the entire body with vibrations, regardless of whether for reasons of well-being, comfort, massage or therapeutic purposes. The vibration generation should be able to be easily adapted to the individual body dimensions and lying position of the user of the mattress and should also be easily accessible in the event of a malfunction or for maintenance of the vibration generator in the mattress. In a further refinement, the mattress should also be optimized as far as possible in terms of its properties in order to avoid bedsores or decubitus.

According to the invention, this object is achieved by a mattress with the features of the appended claim 1. Preferred configurations, developments and uses of the invention emerge from the dependent claims and the following description with associated drawings. A mattress according to the invention with a lying surface for a user comprises a foam-like, elastic mattress core and a spacer fabric arranged on the mattress core, the mattress core having a vibration cavity which is provided and designed in such a way that a vibration device, which is one of an electric motor includes driven unbalanced mass, can be arranged to generate vibrations in the mattress, and has the special feature that the vibration device is designed as a rod, cylinder or tubular vibrating rod in which the electric motor and the unbalanced mass are arranged. In addition, the mattress core has several vibration cavities, each of which is designed to insert the vibration rod and to enclose the vibration rod inserted therein along its circumferential direction, and which are parallel to one another. other in the transverse direction of the lying surface are arranged in an area below half of the lying surface, in which, when the mattress is used as intended, the lower legs of a user of the mattress lying on his back on the lying surface are located, so that the position of the vibration rod can be adapted to the individual Kör permaße of the user and his lying position on the lying surface of the vibration rod can be introduced into a vibration cavity, which is located under half of the middle of the user's calves. In the context of the invention, it was found that such a mattress with a vibration device achieves the above-mentioned objects. If a vibration rod is arranged in the mattress below the middle of the calf of the user of the mattress, i.e. below the middle of the respective gastrocnemius muscle (also known as the double-bellied calf muscle or twin calf muscle) of his legs as seen in the longitudinal direction of the leg, if he is lying on his back with the legs stretched With the legs lying on the bed, the vibrations generated by the vibration rod in the mattress core are transmitted via the spacer fabric not only to the calf muscle, but to the entire body of the user. It is assumed that the vibrations generated by the vibrating rod not only propagate in the mattress core and are transmitted from there to the body via the knitted spacer, but that the vibrations also propagate in the knitted spacer over the lying surface, although it does has a lower strength and higher elasticity than the mattress core. At least in the context of the invention it was found that with an overlay made of a knitted spacer fabric on the mattress core or on the mattress, the vibrations are better transmitted to the user than without knitted spacer fabrics. According to a preferred embodiment, it is proposed in particular that the vibration device comprises only one vibration rod, that is to say only one vibration rod in one of the vibration cavities in the mattress core is used. As a result, the outlay on equipment can be reduced compared to the prior art and a vibrating mattress can be manufactured inexpensively. The individual adaptation to a user by inserting or transferring a vibration rod into the vibration cavity that is appropriately arranged in the mattress is then uncomplicated because only one vibration rod has to be positioned and the positioning instructions ("in the middle the calf or the lower leg ") can be carried out in an uncomplicated manner without a measuring device solely by eye, even for a user without medical-anatomical knowledge. Likewise, the adjustment of the position of the vibrating bar to another user of the mattress is quick, easy and inexpensive by removing the vibrating bar from a vibrating cavity and inserting it into a vibrating cavity that matches the other user. A suitable vibration cavity in this sense is that vibration cavity that has the smallest distance to the Stel len of the lying surface where the middle of the calves of the user of the mattress rest on the lying surface when he is intended to lie on the lying surface in the supine position with his legs straight. Surprisingly, it has been shown within the scope of the invention that the mattress is also suitable for treating the entire body with vibrations with just one vibrating rod, regardless of whether for reasons of well-being, comfort, massage or therapeutic purposes. If the vibration rod is positioned correctly below the middle of the calves of the mattress user, the user feels the vibrations throughout the body, not just in the lower legs, but also in the thighs, in the pelvis, in the trunk, in the chest and in the back , in the throat and also in the head. In most cases, the user cannot even perceive the position of the vibration rod, but simply feels that vibrations are spreading throughout his body without being able to determine or say where or which places the vibrations in his Bodies are coupled. Such a quasi delocalized vibration excitation that spreads over the entire body is perceived as more pleasant than vibrations that are perceptibly focused on a part of the body.

Such a pleasant, effective and uniform vibration excitation of the entire body with only one vibrating rod cannot be achieved if the vibrating rod is placed in the mattress in the vicinity of a point on the body other than the middle of the calves. In particular, no significant vibrations are transmitted to the pelvis and legs when the vibration rod is placed in the chest area. It is assumed that this is based on the fact that the strongest muscle groups are located in the lower part of the body, which means that it is muscular, stronger and dominant compared to the upper body. As a result, the vibrations of the vibration rod can be passed on from the middle of the calves to the upper body in a comfortable and efficient way via the entire, strong and dominant leg, gluteal and pelvic muscles. In the opposite direction, i.e. from the weaker upper body muscles to the lower body, this is not so pleasant and effective due to the muscle strength ratio between the upper and lower body.

The invention is explained in more detail with reference to exemplary embodiments shown in the figures. The particularities described therein can be used individually or in combination with one another in order to create preferred embodiments of the invention. Identical or identically acting parts are denoted by the same reference symbols in the various figures and are usually only described once, even if they can be used advantageously in other embodiments. Show it: Figure 1 is a perspective view of a mattress according to the invention ze,

FIG. 2 shows a plan view of the mattress of FIG. 2, FIG. 3 shows a vibration bar for the mattress of FIG. 2, FIG. 4 shows a longitudinal section of FIG. 3 and FIG. 5 shows a modification of FIG. 4.

FIG. 1 illustrates in a perspective view an exemplary embodiment of a mattress according to the invention with a lying surface for a user. The term "mattress" refers to a cushion that allows you to lie comfortably. Such a mattress 1 is preferably ergonomically adapted to a user for the most relaxed possible lying position. This leads to a relief of the spine and the back muscles. A mattress 1 is placed on a substructure (not shown), preferably a slatted frame.

The mattress 1 is a body with six substantially rectangular surfaces, the angles of which are all right angles. The mattress 1 thus comprises an upper surface 3 on the upper side, a lower surface 4 on the lower side, two end surfaces 5, 6 and two side surfaces 7, 8. The opposing surfaces of a mattress 1 are congruent, that is, congruent, so that in principle the upper surface 3 or the lower surface 4 can be used as a lying surface 2 for a user. A "lying surface" is to be understood as the surface of the mattress 1 on which a user can lie, that is, the upper surface 3 or the lower surface 4 of the mattress 1. In most mattresses, both the upper surface 3 and the lower Area 4 used as a lying area 2 who the, that is, the mattress 1 can be turned. The upper 3 and lower 4 surfaces can be the same or different (e.g. with regard to the degree of hardness of the mattress 1 on this surface or the heat and / or moisture properties of the cover on this surface) be designed. In some mattresses, however, their orientation is given, that is, they have only one lying surface 2 (on the upper surface 3 on the top of the mattress) and cannot be turned. The mattress 1 according to the invention is such a mattress which has only one lying surface 2.

The lying surface 2 comprises a head end 9 at an upper end 10 of the lying surface 2 of the mattress 1 and a foot end 11 at the lower end 12 of the lying surface 2 of the mattress 1, which is opposite the head end 9. The lying surface 2 expands in its longitudinal direction from the head end 9 to the foot end 11. The longitudinal direction of the mattress 1 or the lying surface 2 runs parallel to the lying surface 2 and the side surfaces 7, 8 from the upper end face 5 to the lower end face 6. The transverse direction of the mattress 1 or the lying surface 2 runs transversely to the longitudinal direction , namely parallel to the lying surface 2 and the end faces 5, 6 from the left side surface 7 to the right side surface 8. If a user is intended to lie on the lying surface 2 of the mattress 1, he lies in the longitudinal direction on the lying surface 2 and is in such a way on the Lying surface 2 aligned that his head in the area of the head end 9 and his feet in the area of the foot end 11 on the lying surface 2 of the

Mattress 1 are located. The upper end face 5 extends at the head end 9 in the transverse direction of the mattress 1, and correspondingly at the foot end 11 the lower end face 6. Left and right (based on the left and right side of the body of a user lying on the mattress 1 in a supine position) on the sides of the The left side surface 7 and the right side surface 8 extend in the longitudinal direction of the mattress 1.

A mattress 1 according to the invention can have any dimensions aufwei sen. It preferably has commercially available dimensions, relating to the size of the lying surface 2 and / or the height Hl of the mattress. Commercially available sizes have a width Bl between 70 cm and 220 cm and a length LI between 180 cm and 220 cm, common heights Hl are genes between 14 cm and 26 cm. A commercial size mattress 1 has the advantage that it fits into a standard bed system and customary covers, sheets and blankets can be used for which no custom-made product is required.

The mattress 1 comprises a foam-like, elastic mattress core 13 and a knitted spacer fabric 14 arranged on the mattress core 13, the mattress core 13 having a vibration cavity which is provided and designed in such a way that a vibration device, which is one of an electric motor includes driven imbalance mass, can be arranged to generate vibrations in the mattress.

In order to achieve the desired support for the spinal column, the pelvis and the shoulder area of a user, the material of the mattress core 13 arranged on the underside of the mattress 1 consists of a foam-like, elastic material. The mattress core 13 is a compact body with a cellular pore structure and thus ensures good climate regulation. It has permanent elasticity and a high restoring force. The mattress core 13 can consist of one layer or of several superimposed layers, which are preferably connected to one another over a large area, e.g. B. be made by gluing. In the mattress core 13 ventilation channels or air chambers can be formed from. In advantageous embodiments, the height h13 of the mattress core 13 is between 8 cm and 30 cm, preferably between 10 cm and 20 cm.

The material of the mattress core 13 is preferably made of a foam such as cold foam, viscose foam, viscose foam, polyurethane foam, polyether foam, thermoplastic material with memory function (with shape memory effect), latex or latex foam (z. B. based on vulcanized natural rubber or synthetic latex). A mattress core 13 with a spring core structure is less suitable for a mattress 1 according to the invention, because cavities for inserting a vibration device can only be formed in it with great effort.

A knitted spacer fabric 14 is arranged above the mattress core 13. In principle, any knitted spacer fabric 14 known from the prior art is suitable for this purpose. To be particularly suitable the spacer 3DEA ^® has proven to be the manufacturer Essedea in water senberg (DE) of polyester filaments in the invention. This is an innovative material that is used in various ways in the area of bed furnishings. It consists of pressure-elastic monofilament threads (PET) that are joined together to form a three-dimensional spacer fabric that is dynamic in terms of load changes. It not only transmits vibrations very well, but is also characterized by the following features: dimensional stability, excellent point elasticity, high pressure relief, very pronounced breathability (air regulation), very good ability to thermoregulate (climate regulation), optimal, air-permeable microclimate with a balance between moisture and warmth, very good resilience, perfect pressure distribution and contour adaptation, maximum comfort. It therefore offers optimal climate comfort and optimal pressure relief. It is also hygienic as it can be washed at up to 60 ° C. The height h14 of the knitted spacer fabric 14 can for example be between 10 mm and 55 mm, a height between 35 mm and 45 mm having proven to be particularly advantageous. The degree of hardness of the layer made of the knitted spacer fabric 14 can be designed from soft to firm according to the needs of the user. It is also possible in the longitudinal direction of the mattress 1 to divide the knitted spacer 14 into different pressure zones with different degrees of hardness, for example In the area of the shoulders and / or the pelvis, a softer spacer fabric allows the user to sink more deeply.

Furthermore, the mattress core 13 has vibration cavities 15 which are provided and designed in such a way that a Vibrationsvor direction, which comprises an unbalanced mass driven by an electric motor, can be arranged in them for generating vibrations in the mattress 1. The vibration device is thus arranged in a vibration cavity 15 in the mattress core 13. The vibration device is designed as a rod, cylinder or tubular vibration rod in which the electric motor and the unbalanced mass are arranged. Corresponding to the rod, cylinder or tubular shape of the vibration rod, the vibration cavities 15 are of a corresponding elongated shape. The vibration cavities 15 are formed to enclose the vibration rod inserted therein along its circumferential direction. Furthermore, the vibration cavities 15 are arranged parallel to one another in the transverse direction of the lying surface 2 in an area below the lying surface 2, in which, when the mattress 1 is used as intended, the lower legs of a user of the mattress 1 lying on his back on the lying surface are located, So in the area of the foot end 11 of the bed surface 2, so that to adjust the position of the vibration rod to the individual body dimensions of the user and his lying position on the bed surface 2, the vibration rod can be introduced into a vibration cavity 15, which is located below the middle of the user's calves .

In Figure 1, an embodiment is shown in which, according to an advantageous feature, the vibration cavities 15 extend up to at least one side surface 7, 8 of the mattress 1 and the mattress core 13 on at least one side surface 7, 8 of the mattress 1 each to the Vibration cavities 15 has associated insertion openings 15a, through which the vibration rod can be inserted into a vibration cavity 15. On at least one side surface 7, 8 of the mattress 1, im illustrated embodiment on the left side surface 7, the mattress core 13 thus has several insertion openings 15a, which are each formed as a cavity or channel for inserting a vibration rod, which is a rod, cylinder or tubular vibration rod in which the electric motor and the Eccentric mass are arranged.

The insertion openings 15a are arranged parallel to each other in the transverse direction of the lying surface in an area below the lying surface 2, in which, when the mattress 1 is used as intended, the lower legs of a user of the mattress 1 lying in the supine position with legs stretched on the lying surface 2 are located. As a result, to adapt the position of the vibration rod to the individual body measurements of the user and his lying position on the lying surface 2, the vibration rod can be pushed or inserted through an insertion opening 15a into a vibration cavity 15 which is located below the calves in the middle of the user. In this embodiment, the cables for the power supply of the vibrating rod can expediently be passed through the cavity or channel formed by the insertion opening 15a to the vibrating rod.

In order to facilitate the introduction of the vibrating rod into a vibration cavity 15, for example during the manufacture of the mattress or in particular special for a frequent adjustment of the position of the vibrating rod in the mattress 1 to a new user, for example in a clinic or a hotel, can advantageously be provided that the Vibra tion cavities 15 each have a cavity slot running in the transverse direction of the lying surface 2 on their upper side, through which the vibration rod 18 can be inserted into the respective vibration cavity 15. If the vibration cavity 15 is not connected to an insertion opening 15a, the cables for the power supply of the vibration rod can be laid through suitable channels or line slots. In this embodiment, the spacer fabric 14 can with the mattress core 13 are glued, for example with a heat-releasable adhesive. This can be advantageous if the position of the vibration rod is to be determined and secured against manipulation, for example for a specific user to whom the mattress 1 is adapted. Preferably, the knitted spacer 14 is only loosely placed on the mattress core 13, then the position of the vibrating rod can easily be changed by lifting the knitted spacer 14, removing the vibrating rod from a vibration cavity 15 through its cavity slot and inserting it into another vibration cavity 15 through its cavity slot .

In order to facilitate the introduction of the vibration rod into a vibration cavity 15, for example during the manufacture of the mattress or in particular for frequent adjustment of the position of the vibration rod in the mattress 1 to a new user, for example in a clinic or a hotel, in some embodiments advantageously be seen before that the mattress core 13 has a mattress slot that runs parallel to the lying surface 2, from the left side surface 7 to the right side surface 8 of the mattress 1 and from the lower end surface 6 of the mattress 1 through the vibration cavities 15. If the vibration cavity 15 is not connected to an insertion opening 15a, the cables for the power supply of the vibration rod can be laid through suitable channels or line slots. In this embodiment, the parts of the mattress core divided by the mattress slot can be glued, for example with a heat-releasable adhesive. This can be advantageous if the position of the vibration rod is to be set and secured against manipulation, for example for a specific user to whom the mattress 1 is adapted. The parts of the mattress core 13 divided by the mattress slot can, however, also be placed loosely on top of one another. Then the position of the vibrating bar can easily be adjusted by lifting the upper slotted part, i.e. unfolding the mattress core along the mattress slot, Removing the vibration rod from a vibration cavity 15 in the gap-shaped unfolded mattress slot and inserting it into another vibration cavity 15 with subsequent closing of the mattress slot can be changed.

When a person uses the mattress 1 with the vibrating rod in the adjusted position, their calf centers are on the lying surface 2 above the vibrating rod inserted into the appropriate vibration cavity 15, for example through an associated insertion opening 15a. This positioning of the vibration rod in the mattress 1 as a function of the body dimensions and the position of the user of the mattress 1 has proven to be particularly advantageous so that the vibrations generated by the vibration rod can act on the user. It is clear that, due to the discrete arrangement of the vibration cavities 15 or the insertion openings 15a as well as variations in the lying position of the user, the positioning of the vibration rod cannot be carried out exactly. In the context of the invention, however, it has been shown that a deviation of the exact position of the vibration rod in the longitudinal direction of the mattress 1 of up to 10 cm is acceptable without affecting the properties of the mattress 1 or the vibration transmission from the vibration rod to the user worsen appreciably or practically significantly.

The vibration cavities 15 or insertion openings 15a can, as shown in the exemplary embodiment in FIG. 1, be arranged lying next to one another in a plane parallel to the lying surface 2. They are preferably arranged in front of each other at a constant distance A15. This distance A15 between the vibration cavities 15 or a slide-in openings 15a should be as small as possible in order to enable the smallest possible step size for optimal positioning of a vibration rod in the most expediently arranged slide-in opening 15a. However, the distance A15 between the vibration cavities 15 or insertion openings 15a also not be too small in order not to impair the stability and strength of the mattress core 13. It is advantageous if the distance A15 between two adjacent vibration cavities 15 or insertion openings 15a (without an inserted vibration rod) is between 15 mm and 45 mm, preferably between 20 mm and 30 mm. This information relates to the thickness of the material of the mattress core 13 located between the inner sides of two adjacent vibration cavities 15 or insertion openings 15a. In this way, a vibration cavity 15 or insertion opening 15a can always be found that is sufficient is exactly below the middle of the user's calf.

If a very precise positioning of the vibration rod should be required for special applications, which cannot be achieved with such a "step size" of the vibration cavities 15 or insertion openings 15a, the vibration cavities 15 or insertion openings 15a can also be arranged in two or more, one above the other lying, each to the lying surface 2 parallel planes are arranged, the vibration cavities 15 or insertion openings 15a of a plane to those of the other plane in the longitudinal direction of the mattress 1 are offset. In this way, an even finer grid dimension of the vibration cavities 15 or insertion openings 15a for positioning the vibration rod can be achieved. The number of vibration cavities 15 or insertion openings 15a arranged next to one another also depends on their diameter D15. An appropriate number is, for example, between 5 and 15, preferably between 7 and 11. The vibration cavities 15 or insertion openings 15a are advantageously arranged over an area which extends at the foot end 11 of the mattress 1 in the longitudinal direction of the mattress 1 over an area its lower end between 5 cm and 30 cm, preferably between 10 cm and 20 cm from the lower end face 6 of the Mattress 1 removed and the upper end of which is between 25% and 40%, preferably between 30% and 35% of the length LI of the mattress 1 from the lower end face 6 of the mattress 1. In this way, the area of the feet is spared over an initial length La, and the vibration cavities 15 or insertion openings 15a are arranged in the area of the knees for some users. Roughly speaking, the vibration cavities 15 or insertion openings 15a are approximately in the area of the lower third of the lying surface 2 of the mattress 1. A mattress 1, which has several vibration cavities 15 or insertion openings 15a, can in principle have one or more vibration bars, each in a vibration cavity 15 are arranged. As explained above, a preferred embodiment is that it comprises only one vibrating rod which is inserted into a vibrating cavity 15.

The vibration cavities 15 are formed to enclose the vibration rod inserted therein along its circumferential direction. This has several advantages. On the one hand, the positioning and attachment of a vibrating rod is easy for a user of the mattress 1 to carry out because he can simply insert the vibrating rod into one of the existing Vibra tion cavities 15 and does not have to carry out complex assembly. On the other hand, by enclosing the vibration rod along its circumferential direction with the material of the mattress core 13, noises which can emanate from the vibration rod during operation are well shielded and attenuated on all sides. In addition, the vibrations of the vibration bar are thereby decoupled from other parts of the bed, for example a substructure, slatted frame or bed frame, and thus concentrated on the mattress 1. Furthermore, a good transmission of the vibrations generated by the vibrating rod to the mattress core 13 is thereby also achieved. In order to achieve good transmission of the vibrations generated by the vibrating rod to the mattress core 13, it is proposed according to an advantageous feature that the inner diameter D15 of the vibrating cavities 15 or insertion openings 15a be matched to the outer diameter of the vibrating rod in such a way that the vibration rod can be introduced into the vibration cavities 15 in a form-fitting or non-positive manner. Preference is given to a non-positive enclosing of the vibration rod along its circumferential direction by the elastic mattress core 13. This is achieved when the inner diameter D15 of the vibration cavities 15 (without the vibration rod inserted) are smaller than the outer diameter of the vibration rod, so that the vibration rod has the vibration cavity 15 in its Diameter D15 stretches when inserted into it. So that the introduction of the vibration rod into the vibration cavity 15 and accordingly the removal in the case of positioning in another vibration cavity 15 is not possible manually with a force that is not too great and it does not cause a strong deformation of the mattress core 13 or even damage to the mattress 13 comes, it is advantageous if the inner diameter D15 of the vibration cavities 15 (without the inserted vibration rod) between 70% and 90%, preferably between 75% and 85% of the outer diameter of the vibration rod.

An advantageous embodiment consists in that the vibration cavities 15 or insertion openings 15a are designed for inserting (inserting or pushing in) a vibration rod, the outer diameter of which is between 2.5 cm and 8 cm, preferably between 3 cm and 6 cm. In this area, the outer diameter is large enough to generate sufficiently strong vibrations at a given speed of the vibration device, and small enough to be able to be accommodated in the mattress core 13. In order to achieve a good transmission of the vibrations generated by the vibration rod from the mattress core 13 to the spacer fabric 14, it is proposed according to an advantageous feature that the vibration cavities 15 be located just below the top of the mattress core 13, that is, at a small distance from the Underside of the

Spacer fabric 14 are arranged. Accordingly, it is advantageous if the distance A14 of the vibration cavities 15 or insertion openings 15a (without the inserted vibration rod) to the top of the mattress core 13 or to the bottom of the spacer fabric 14 resting on it is between 15 mm and 45 mm, preferably between 20 mm and is 30 mm. This information relates to the height of the material of the mattress core 13 located between the inside of the vibration cavities 15 or insertion openings 15a and the top of the mattress core 13.

In order to ensure good transmission of the vibrations generated by the vibrating rod from the knitted spacer fabric 14 to the user of the mattress 1, it is proposed according to another advantageous feature that the mattress 1 be between the knitted spacer fabric 14 and one lying on the lying surface 2 of the mattress 1 User only has a mattress cover and / or a mattress pad and / or a mattress cover. This means that no layer of the mattress 1 is arranged on the knitted spacer fabric 14 which consists of a material similar to that of the mattress core 13. Another advantage of this embodiment is that it counteracts bedsores or bedsores. A mattress cover or a mattress pad can, for example, be a solid fabric made of an elastic material, e.g. B. Terrycloth and / or multi-layer jersey. It can be padded and / or consist of sheep's wool, fleece, cotton, wild silk, polyester and / or horsehair and be quilted. In embodiments in which the user wants a further mattress layer on the knitted spacer fabric 14 made of a material similar to the mattress core 13 or if this should be necessary for a reason, this further mattress layer should preferably be thin. Accordingly, it is proposed according to an advantageous feature that the mattress 1 has a mattress layer between the knitted spacer fabric 14 and a user lying on the lying surface 2 of the mattress 1, the height of which is not more than the height h14 of the knitted spacer fabric 14, preferably not more than 75% of the height h14 of the spacer fabric 14 is. This embodiment also has the advantage that a wound lies or pressure ulcers are counteracted.

In the exemplary embodiment in FIG. 1, the mattress 1 has no further mattress layer on the knitted spacer fabric 14. The concrete dimensions in this embodiment are as follows. The length of the mattress 1 is 200 cm, the width 100 cm. The height h13 of the mattress core 13 is 12 cm, the height h14 of the knitted spacer fabric 14 is 44 mm. The nine vibration cavities 15 with insertion openings 15a have an inner diameter of 33 mm. Their distance A15 from one another is 22 mm and they are arranged in a plane lying parallel to the lying surface 2. As a result, the vibration rod can be positioned in the longitudinal direction of the mattress 1 by inserting it through one of the insertion openings 15a into a vibration cavity 15 with an accuracy of 27.5 mm (half the distance between the axial centers of the vibration cavities 15 or insertion openings 15a). The distance A14 of the vibration cavities 15 or insertion openings 15a to the top of the mattress core 13 is also 22 mm. The distance La of the vibration cavity 15 or the insertion opening 15a, which is located closest to the lower end face 6 of the mattress 1, is 15 cm.

FIG. 2 shows a plan view of the lying surface 2 of the mattress 1 from FIG. 2. The vibration cavities 15 with insertion openings can be seen. openings 15a, which are designed as cylindrical cavities (holes, bores) that are geöff net towards at least one side surface 7 of the mattress 1, so that a vibration rod can be inserted from this side surface 7 through the insertion openings 15a into the vibration cavities 15. A preferred embodiment is shown, according to which all insertion openings 15a of mattress 1 are arranged on the same side surface 7 of mattress 1, that is to say all vibration cavities 15 are open to the same side surface 7. This makes it easier to find the appropriate insertion opening 15a if the position of the vibration rod is adapted to another user of the mattress by inserting it into another vibration cavity 15, since only one side of the mattress 1 has to be handled for this purpose.

Due to the plurality of vibration cavities 15 or insertion openings 15a, the location of the vibration generation in the mattress 1 can be easily adapted to the individual body dimensions and lying position of the user of the mattress 1 and also in the case of a The vibration rod is easily accessible for a malfunction or for maintenance of a vibration generator in the mattress 1.

The vibration cavities 15 or insertion openings 15a can advantageously extend from the left side surface 7 to the right side surface 8 of the mattress 1, that is, be continuous cavities. In this case, a vibration rod inserted into a vibration cavity 15 can not only be pulled out of an insertion opening 15a by pulling on its connecting cable, but can also be pushed out by inserting a rod into an insertion opening 15a on the opposite side.

According to a particular embodiment shown, it is proposed that the vibration cavities 15 are designed as blind holes that extend to a side surface 7 of the mattress 1, and the mattress zenkern 13 on the side surface 7 of the mattress 1 each to the Vibra tion cavities 15 belonging insertion openings 15a through which the vibration rod can be inserted into the vibration cavity 15. In this case, the vibrating rod can only be inserted from one side surface 7 of the mattress 1 through insertion openings 15a in vibration cavities 15 until it rests on the bottom of the blind hole. This has the advantage that the depth T15 of the blind holes formed by the vibration cavity 15 and insertion opening 15a can be matched to the dimensions of the vibration rod in such a way that the vibration rod is correctly positioned in the transverse direction of the mattress 1 when it reaches the bottom of the blind hole in the blind hole is introduced. This greatly facilitates the correct positioning of the vibration bar in the transverse direction of the mattress 1 without the need for a measuring or positioning device. The vibration bar is preferably positioned correctly in the transverse direction of the mattress 1 when the center of gravity of the unbalanced mass of the vibration bar is in the middle of the mattress 1 in the transverse direction of the mattress 1. If the vibrating rod has an eccentric body, the center of gravity of the unbalanced mass is the center of gravity of the eccentric body, and if the vibrating rod has several eccentric bodies, the center of gravity of the unbalanced mass is the common center of gravity of the eccentric bodies.

If the center of gravity of the unbalanced mass is in the middle of the vibrating rod, that is to say halfway along the vibrating rod, the depth T15 of the blind holes is thus advantageously half the sum of the width B1 of the mattress 1 and the length of the vibrating rod. In advantageous embodiments it is provided that the insertion openings 15a are designed for the insertion of a vibration rod which is between 25 cm and 60 cm, preferably between 30 cm and 50 cm long. For a mattress 1 with a width Bl of 100 cm it results accordingly that the depth T15 of the blind holes between 62.5 cm and 80 cm, preferably between 65 cm and 125 cm, if the focus of the unbalanced mass is in the longitudinal direction of the vibrating rod in the middle of the vibrating rod. In the embodiment of Figure 2, the length of the vibrating rod is 38.6 cm, so that the depth T15 of the blind holes from vibration cavity 15 and insertion opening 15a is 69.3 cm when the center of gravity of the unbalanced mass in the longitudinal direction of the vibrating rod is in the middle of the vibrating rod . If the center of gravity of the unbalanced mass, however, is closer to the end of the vibrating rod that is closer to the side surface 7 from which the vibrating rod is inserted into the blind hole, the depth T15 of the blind hole increases accordingly. If the center of gravity of the unbalanced mass is closer to the end of the vibrating rod which is further away from the side surface 7 from which the vibrating rod is pushed into the blind hole, the depth T15 of the blind hole is correspondingly reduced.

In order to ensure good transmission of the vibrations generated by the vibrating rod from the knitted spacer fabric 14 to the user of the mattress 1, it is proposed according to an advantageous feature that the knitted spacer fabric extends over the entire length LI and width B1 of the lying surface 2, with possibly a narrow edge area is taken out, in which the knitted spacer is bordered (framed, bordered) by an elastic frame 16. Such a frame 16 can serve to position and / or reinforce the knitted spacer fabric 14. It should be elastic so that the lying surface 2 can be used up to the side and front surfaces of the mattress 1. In Figure 2, this frame 16 is formed by a foam that consists of a material such as a mattress core. In an alternative embodiment, the frame 16 can be formed by reinforcing the edge of the knitted spacer fabric 14. The height of the frame 16 advantageously corresponds to the height of the knitted spacer fabric 14. The width B16 of the frame 16 is advantageously between 1 cm and 6 cm, preferably between 2 cm and 5 cm.

FIGS. 3 and 4 illustrate an exemplary embodiment of a vibration device which comprises an unbalanced mass driven by an electric motor 17 and which can be introduced into one of the vibration cavities 15 in order to generate vibrations in the mattress 1. FIG. 3 shows a view of the vibration device designed as a rod, cylinder or tubular vibrating rod 18 with the electric motor 17 and the unbalanced mass, and FIG. 4 shows a longitudinal section A-A 'to FIG.

The vibration rod 18 serves as a vibration generator for generating oscillations or vibrations. It is inserted into a vibration cavity 15 suitable for the user, for example inserted through an insertion opening 15a or inserted through a cavity slot or mattress slot, so that the vibrations are transmitted to the mattress core 13 and from there via the spacer fabric 14 to the user of the mattress 1 will.

Vibrations can be generated in different ways, for example by means of a coil with a vibrating iron core or a piezoceramic. A vibration device which comprises an unbalanced mass driven by an electric motor is best suited for a mattress according to the invention. Such vibration devices are designated as a vibration motor or as an unbalance motor or vibrating motor. A vibration motor is a rotary machine on the shaft of which an unbalanced mass is attached which is arranged eccentrically to the shaft and which is formed from an eccentric body or several eccentric bodies. The centrifugal forces that occur in the eccentric body, which moves in a circle when the shaft rotates, generate circular mechanical ones during operation Vibrations that lead to a vibration of the arrangement. The unbalanced mass is also known as the flywheel.

In the prior art, vibration motors are also referred to as eccentric motors, which include an eccentric with an eccentric body driven by the electric motor. In mechanics and mechanical engineering, an eccentric (from the Latin ex centro 'out of the middle', meaning 'moved out of the center') is a control disc attached to a shaft, the center of which is outside the shaft axis. With an eccentric, rotary movements (rotary movements) can be converted into translatory movements (longitudinal movements) and vice versa. If, on the other hand, an eccentrically arranged eccentric body is set in rotary motion with the eccentric, this movement can be perceived as a vibration or oscillation, and the eccentric motor serves as a vibration motor. A vibration motor does not generate a one-dimensional, but a two-dimensional superimposed vibration due to the way in which the vibrations are generated by a rotating eccentric body. The rod-shaped, cylindrical or tubular vibrating rod 18 shown in FIGS. 3 and 4 comprises a housing 19, the length L19 of which is greater than its outer diameter D19. The outer diameter D19 is preferably between 2.5 cm and 8 cm, preferably between 3 cm and 6 cm. The length L19 is preferably between 25 cm and 60 cm, preferably between 30 cm and 50 cm. The outer diameter D19 is preferably between 1/20 and 1/5, preferably between 1/15 and 1/7 of the length L19. In the exemplary embodiment, the outer diameter D19 of the housing 19 is 40 mm and the length L19 is 386 mm, so that the ratio is approximately 1:10.

The housing 19 encloses a chamber 20 in which the electric motor 17, a shaft 21 driven by the electric motor 17 and an eccentric terkkörper 22 are located as an unbalanced mass. The housing 19 can be formed from a tube-like part which is closed at both ends with end caps 23, or only have an end cap 23 at one end and be solid at the other end. In FIG. 4, the vibration rod 18 has an end cap 23 which is formed by the housing 19 of the attached electric motor 17. In the chamber 20, the electric motor 17 is arranged, which is coupled to an eccentric body 22 by means of a shaft 21 in order to set the vibration rod 18 in vibration when the shaft 21 is rotated due to the imbalance of the eccentric body 22. The shaft 21 is at its ends with a bearing 24, 25 gela Gert. A reduction gear 26 and / or one or two clutches 27, 28 can be located between the electric motor 17 and the shaft 21. The shaft 21 of the vibration motor is mounted in two bearings 24, 25, via which an unbalance torque generated by the eccentric body 22 is transmitted to the housing 19. The shaft 21 runs in the axial direction of the vibration bar 18. When the vibration bar 18 is inserted into a vibration cavity 15 of the mattress 1, the shaft 21 of the vibration motor thus runs in the transverse direction of the lying surface 2. The vibrations or vibrations generated by the vibration motor. Vibration forces thus advantageously have both a component perpendicular to the lying surface 2 and a component parallel to the longitudinal direction of the lying surface 2 or the mattress 1.

The eccentric body 22 is attached to the shaft 21 and serves as an unbalanced mass. It is a cylindrical body which is arranged in the axial direction of the shaft 21. It can also be formed in one piece with the shaft 21. The vibration rod 18 preferably has only a single eccentric body 22. In other embodiments, several eccentric bodies 22 can also be provided, which form a common unbalanced mass. With it the generated vibrations are perceived as pleasant and uniform as possible, it is advantageous if the length L22 of the eccentric body 22 is between 8 cm and 40 cm, preferably between 10 cm and 25 cm. In the exemplary embodiment shown, it is 16 cm in FIG. 4 and 10.5 cm in FIG. 5.

In the exemplary embodiment of FIGS. 3 and 4, the center of gravity of the eccentric body 22 or the unbalanced mass is in the middle of the vibrating rod 18, that is to say halfway along the vibrating rod 18, and is equidistant from both ends. In order to ensure that the focus of the eccentric body 22 or the unbalanced mass is in the middle of the vibrating rod 18, that is half the length of the vibrating rod 18, the length of the housing 19, the position of the electric motor 17 in the housing 19 and the length of the end caps 23 can be varied.

The electric motor 17 can be connected to a power supply via one end of the vibrating rod 18. For this purpose, a power cable 29 is passed through an end cap 23 through a cable bushing 30, which also serves to relieve strain on the power cable 29. Instead of a cable bushing 30, a connection socket can be placed in the end cap 23, into which the plug of a power cable can be inserted. In special embodiments, a battery compartment for receiving one or more batteries or accumulators for supplying energy to the electric motor 17 can be arranged in the vibration rod 18. In such a battery compartment, rechargeable accumulators can also be inserted, which can be charged over and over again via a power cable 29. In operation, the shaft 21 has a speed of less than 100 revolutions per second, preferably between 0.1 and 30 revolutions per second. Can be particularly efficient and physiologically advantageous Generate vibrations with a vibration rod 18, in which the distance between the axis of inertia of the eccentric body (s) 22 and the geometric axis of rotation of the eccentric body (s) 22 is between 30% and 85% of the radius of the circular surface that is swept over by the eccentric body (s) 22 during operation becomes. This circular area is slightly smaller than the inner diameter of the chamber 20 in the vibration rod 18. Preferably, the distance between the aforementioned axis of inertia and the geometric axis of rotation of the eccentric body 22 is between 35% and 75%, particularly preferably between 40% and 60%, in particular between 40% and 50%, the radius of the mentioned circular area. Before given, the eccentric body 22 or the eccentric bodies are cylindrical, so that their axis of inertia coincides with their geometric longitudinal axis. FIG. 5 shows a modification of the vibrating rod 18 from FIG. 4. The differences from the vibrating rod 18 from FIG. 4 are as follows. The housing 19 is hollow and has two end caps 23, 31. No reduction gear is provided, so that the electric motor 17 is connected directly to the shaft 21 via a coupling. The length L19 of the vibrating rod 18 is 380 mm and its diameter D19 is 40 mm. The length L22 of the eccentric mass 22 is 10.5 cm. The center of gravity of the unbalanced mass is in the middle of the vibrating rod. If the eccentric mass 22 is extended into the free cavity without other parts being adjusted, the center of gravity of the unbalanced mass is closer to the end of the vibrating rod 18 that is further away from the side surface from which the vibrating rod 18 enters the Blind hole is inserted, is therefore located further away from the end cap 23 with the cable bushing 30 and closer to the other end of the vibrating rod 18. The other features correspond to those of the vibrating rod 18 of FIG. Advantageous features of a mattress 1 according to the invention can be summarized as follows. The mattress 1 has a lying surface 2 for a user. It comprises a mattress core 13 and a spacer fabric 14 arranged on the mattress core 13. The mattress core 13 has several vibration cavities 15, each of which is designed as a cavity or channel for inserting a vibrating device designed as a vibrating rod 18 and which are parallel to one another in the transverse direction of the bed surface 2 are arranged running in an area below the lying surface 2, in which, when the mattress 1 is used as intended, the lower legs of a user of the mattress 1 lying in the supine position on the lying surface 2 are located, so that the position of the vibration rod 18 can be adjusted to the individual body dimensions of the user and his lying position on the lying surface 2 of the vibration rod 18 can be inserted into a vibration cavity 15, which is located below the middle of the user's calves.

In a mattress 1 according to the invention, the combination of vibrations generated by a vibrating rod 18 arranged in the mattress 1 with a knitted spacer fabric 14 and the optimal positioning of the knitted spacer fabric 14 and the vibrating rod 18 create bedsores (decubitus) for a user of the mattress 1 largely excluded. In order to enable the user to use the mattress 1 in a variety of ways, it can be advantageous to equip it with an operating or control unit (not shown) that allows the speed of the vibration motor and thus the vibration frequency of the vibration rod 18 to be set in a physiologically advantageous range , for example below 50 Hz, allows.

Such an operating or control unit is a handy device for activating or regulating the vibration rod 18 or the electric motor 17, which is connected to the electric motor 17 or to the power supply of the electric motor 17 in a wired or wireless manner. The operating or the control unit offers the possibility, for example, of regulating the duration and / or intensity of the oscillations of the vibration rod 18, as well as defining the time interval between individual vibration applications or a temporal course of the vibration applications. For example, by regulating the speed of the electric motor 17, different vibration frequencies and, indirectly, Vibrationsampli tuden can be realized.

Such an operating or control unit for the vibrating rod 18 can, for example, not only offer the user a manual mode, but also preset programs.

In the manual mode, the user can, for example, set a frequency of the oscillation of the vibrating rod 18 between 0.1 Hz and 30 Hz in a selectable manner. In addition, you can also offer him the option of setting a timer so that the vibration ends automatically after a period that can be set with it or after a predetermined period, for example if the user cannot switch it off manually because he has fallen asleep.

A program of the operating or control unit for the lymph flow is characterized by a constant low vibration frequency between 10 Hz and 20 Hz. It can take, for example, 10 minutes to 15 minutes, at the beginning the vibration frequency of the vibrating rod 18 increases rapidly, for example in 5 seconds to 25 seconds, to 15 Hz, then remains constant and at the end quickly, for example in 5 seconds to 25 seconds, again goes back to zero.

A program of the operating or control unit for activating the blood circulation is characterized by a constant high vibration frequency between 20 Hz and 30 Hz. It can take, for example, 10 minutes to 15 minutes, with the vibration frequency of the vibrating rod at the beginning rises rapidly, for example in 5 sec to 25 sec, to 25 Hz to 30 Hz, then remains constant and at the end quickly, for example in 5 sec to 25 sec, goes back to zero. A program of the operating or control unit for a complex treatment is characterized by a vibration frequency that gradually decreases from a high initial value. It can take, for example, 20 minutes, at the beginning the vibration frequency of the vibrating rod 18 rises rapidly, for example in 5 sec to 25 sec, to 30 Hz, then remains constant for 10 min, then quickly, for example in 5 sec to 25 sec, to 15 Hz falls, then remains constant for 10 min and at the end quickly, for example in 5 sec to 25 sec, goes back to zero.

A program of the operating or control unit for promoting sleep is characterized by a vibration frequency that gradually decreases from a low initial value. It can take, for example, 10 minutes, at the beginning the vibration frequency of the vibrating rod 18 increases rapidly, for example in 5 seconds to 25 seconds, to 15 Hz, then remains constant for 5 minutes, then quickly, for example in 5 seconds to 25 seconds, to 12 Hz drops, then remains constant for 2 min, then drops rapidly, for example in 5 sec to 25 sec, to 10 Hz, then remains constant for 3 min and at the end quickly, for example in 5 sec to 25 sec, like that to zero going back. A program of the operating or control unit for promoting waking up, which can be started either manually or by a timer, is characterized by a gradual increase in the vibration frequency to a high end value. It can take, for example, 7 minutes, at the beginning the vibration frequency of the vibrating rod increases rapidly, for example in 5 sec to 25 sec, to 15 Hz, then remains constant for 2 min, then increases quickly, for example in 5 sec to 25 sec 25 Hz increases, then remains constant for 2 min, then quickly, for example wise in 5 sec to 25 sec, increases to 30 Hz, then remains constant for 2 min and at the end quickly, for example in 5 sec to 25 sec, goes back to zero.

Depending on the selection of the oscillation frequency and / or a corresponding program sequence, positive effects on the body can be achieved with the mattress 1 according to the invention. These include the following:

Optimal blood flow to the tissue and stimulation of the metabolism

Activation of the nervous system and motor skills Accelerated regeneration of damaged nerves Increased lymph flow and the associated removal of edema and waste products

Positive influence on the release of messenger substances for pain, stress and well-being

Particularly in the area of health, there are the following advantages:

Improvement of the blood circulation, among other things to promote healing processes and for pressure ulcer prophylaxis Relief of pain Increase of well-being Stabilization of the circulation Prevention of osteoporosis

Improvement of motor skills, body balance, flexibility and mobility

Reduction of muscle atrophy Support rehabilitation measures There are the following advantages, especially in the area of training and sport:

Accelerated muscle build-up Enables faster warming up and loosening - Improvement of the elasticity of muscles, tendons and the range of motion of joints Shortening regeneration times Increase in muscular performance The following advantages arise, especially in the area of wellness: Physical and psychological relaxation Reduction of stress Reduction of cellulite Tightening of the skin

Especially when falling asleep, the optimal lying comfort in connection with calming vibrations, for example falling from 15 Hz to 5 Hz, promotes a quick fall asleep and a deep sleep. Especially when you wake up, the vibrations, for example increasing from 15 Hz to 30 Hz, mobilize the body and improve concentration, so that you start the day better.

Users of the mattress 1 according to the invention can thus use the positive effects on the body and psyche on a daily basis. Since with the mattress 1 the entire body can be made to vibrate easily and in an individually adapted manner, even if only one vibrating rod 18 is inserted in the mattress core 13, it offers health benefits, especially for activating the lymph and promoting blood circulation in the whole body. The vibrations are felt to be pleasant and relaxing. At the same time, bedsores (bedsores) are avoided even when lying down for a long time. List of reference symbols
