A lying surface with several spring elastic elements fits on the mattress side of the frame and the elastic elements are arranged on the lying surface element for easy interchange and the lying surface element itself is arranged on the bed frame for easy interchange. In the assembled state of the bed, sockets on the lying surface element hold corresponding parts of the bed frame section.

Description

The invention relates to a bed, in particular a hospital and / or nursing bed consisting of a bed frame and a bed frame Bed attachment, the bed frame each having at least one lying surface element is provided and the bed surface element on the mattress side several resilient Has elements.

Beds of the aforementioned type are of many different types from the prior art Designs are known and are also used in practice in Health and / or nursing area of z. B. hospitals, old people's and nursing homes as well as used in domestic use. Generic beds serve in particular to provide the patient with a comfortable and, above all, disease or to allow easy-care lying or sitting position. To this end generic sick and / or nursing beds mostly have a lifting device for lifting and lowering the bed attachment relative to the bed frame as well additionally about other adjustment options with regard to the bed frame.

DE 44 16 689, for example, discloses a generic bed. It is known from this publication a bed, in particular a hospital bed, which consists of a Bed frame and a height-adjustable bed attachment in the bed frame with bed frame. For lifting and lowering the bed attachment opposite the bed frame are two independently operable drive motors provided that in combination with a horizontal control device the bed attachment proceed in such a way that a certain, in particular, a horizontal position is maintained.

For example, DE 195 47 206 and EP 0 433 737 each disclose a sick and / or nursing bed with a bed attachment and one bed attachment carrying bed frame. These are via a corresponding lifting device Bed frame and the bed attachment coupled together, the bed attachment opposite the bed frame is movable in height. In order not to rely on additional operating personnel To be instructed is a height adjustment by means of the lifting device possible via a remote control to be operated by the patient.

DE 25 24 727 describes a sick and / or nursing bed with a swiveling one Back and / or legrest known. To enable that at the same time easier and more comfortable pivoting of the back and / or leg rest a secure blocking of the swiveling backrests is guaranteed in every position is, the bed disclosed here has an energy store in the form of an uncontrolled one Gas spring and a mechanical locking device.

All the above-described bed constructions have in common that for training a lying or sitting position in several sections that is suitable for the sick or nursing existing bed frame a mostly resiliently designed lying surface element which is either taken up by the bed frame or that is combined with this. An example of the design The slatted frame is a resilient surface element. The bed mattress is then placed on the slatted frame itself. Conventional slatted frames consist of individual, spaced from each other in the longitudinal direction of the bed frame arranged slat elements, which are mostly made of wood and are partially elastic to improve lying comfort. Is too it is known to use a kind of elastic mesh grid instead of a slatted frame, which holds the mattress stretched in the bed frame. Depending on the purpose and type can this elastic mesh made of metal or plastic be made.

The use of both a slatted frame or a mesh grid of the above Art opens up the advantage that the spring comfort is not only due to the mattress is determined, rather by using such mattresses significantly improved lying comfort achieved.

Contrary to the aforementioned advantage, however, the use of both Slatted frame as well as the use of a net-like mattress holder in particular in the hospital and / or nursing bed area, some significant disadvantages on. For example, it is not uncommon for bedridden patients to be unwanted Deliver body fluids such as urine or the like which then not only soaked bed linen and mattress but also with partial areas the mattress holder, for example the slatted frame, comes into contact. A cleaning, especially one that is hygienic from a medical point of view Meeting demands is not only time-consuming, it can mostly not carried out by a caregiver alone. So is namely first to remove the bed mattress and the bed mattress holder, e.g. B. the slatted frame to turn or erect, so that the underside cleaned can be. This cannot be done by one operator alone. thereupon all parts of the mattress holder must be carefully cleaned. these are with a slatted frame all slats, careful cleaning both upwards as well as the downwards side of each slat includes. The same applies to a mesh-like mattress holder. Also here all individual components must be carefully cleaned, depending on the design of the lattice-shaped mattress holder can be many times more complex than, for example, in comparison for cleaning a slatted frame.

Another very significant disadvantage is that conventional slatted frames are mostly are made of wood. Even in the event that the individual is sealed Slatted frame components is provided, this will wear out over time, so that at least partial areas of the slatted frame unprotected in contact with any leaking body fluids occur. Especially for hygienic reasons this is extremely worrying, because even the most thorough surface cleaning cannot prevent the wood from absorbing liquid. The genesis and spread of potentially harmful germs, bacteria and fungi can adversely result.

To avoid the disadvantages described above, the insert is tub-like trained mattress receptacles known from the prior art. This Mattress holders are used in particular to collect leaked liquids and an uncontrolled flow of the liquid or an uncontrolled one Contacting the liquid effectively with other bed components avoid. However, these known mattresses are only keeping hygienically clean in a very long time. But most of all is the use of such mattress receptacles so limited comfort, that use in the hospital and / or nursing bed area, if at all, is then only possible for a limited time. On the one hand, this is due to the poor suspension comfort justified, because when using an example Made of metal mattress holder all suspension comfort is solely due to the mattress itself, on the other hand when requested Tightness of the mattress holder extensive adjustment options for the lying surface for setting a lying or sitting position that is appropriate for the patient or nursing not possible. In this respect, the use of the mattresses described above is in not satisfactory in any way.

It is therefore an object of the present invention to develop a bed, in particular a hospital and / or nursing bed, while avoiding the disadvantages mentioned above, so that, on the one hand, the highest comfort is guaranteed and, on the other hand, hygienic cleaning of contaminated bed components, in particular in the event of an unwanted loss of fluid, it is possible in a simple and easy manner.

To achieve this object it is proposed with the invention that the resilient elements on the lying surface element and the lying surface element is replaceably arranged on the bed frame.

This configuration according to the invention makes a bed construction for the first time provided that the lying in bed a sufficiently good lying comfort offers what particularly with regard to the use of the invention Bed as a sick and / or nursing bed is important, and which also makes it possible to keep the individual lying surface elements hygienically clean.

The bed frame can preferably be pivoted and moved relative to one another arranged bed frame sections formed, the individual bed frame sections are each provided with at least one lying surface element. To adapt to an individually adjustable lying and / or sitting comfort differently designed lying surface elements with regard to the suspension property different resilient element as required Combine with each other according to the modular principle.

As a result of the combined arrangement of the lying surface element and the spring elastic Element becomes a lying and sitting comfort that meets the highest demands achieved, whereby individual wishes can be taken into account, because the configuration according to the invention opens up the possibility of different Lying surface elements with different resilient elements to combine with each other according to the modular principle. For example resilient to the size or weight of the patient Elements are used so that it is not used for the formation of beds or the like, as is the case with conventional slatted frames or mesh grids is the case. In addition, the arrangement according to the invention enables training of lying surface element and spring-elastic element patient-friendly lying or sitting comfort. So can the individual Bed frame sections of the bed frame with differently acting spring elastic Elements can be equipped so that, for example, in the head area of the Patients are provided a less elastic area, whereas in Pelvic area spring elements are used, their elasticity comparatively is high. Unlike conventional mattress holders, it is therefore through the combined use of a lying surface element and a spring-elastic element individual, patient-related and / or patient-specific comfort embody.

Both the lying surface elements and the resilient elements are arranged interchangeably. This will not only be the possibility of an individual Design of lying comfort created, also ensures interchangeability of the various elements the possibility of an easy to carry out hygienic cleaning because the elements to be cleaned are simple Can be removed and cleaned of impurities. With regard the bed surface element material in particular offers more deep-drawn Plastic or deep-drawn metal. Such lying surface elements are due easy to handle due to their low weight, enable a thorough and above all hygienic cleanliness and are essentially insensitive against acidic or alkaline liquids. For the resilient Element has proven to be particularly suitable for plastic. First, because because using different types of plastic and different Injection molding techniques a variety of different spring element shapes can be trained, also in terms of their suspension properties distinguish, on the other hand the use of plastic is comparatively little expensive, so that an overall economical production is feasible.

Each bed frame section of the bed frame is preferably with a separate one Provide lying surface element. This configuration is particularly advantageous for use in the hospital and / or nursing bed area. So can the individual Bed frame sections are moved or pivoted relative to one another, so that the bed frame as a whole forms a lying surface that is comfortable and above all, a lying or sitting position of the im Allows patients in bed. For this purpose, the individual Bed frame sections each with a preferably one-piece lying surface element Mistake. These individual lying surface elements can with Advantage to be cleaned separately. It is therefore hygienic Cleaning no longer required to clean the entire bed frame, rather it is sufficient to clean only those bed surface elements that require cleaning require. Is z. B. in the case of an unwanted loss of fluid, for example loss of urine, blood or the like, only a single bed surface element accordingly contaminated, whereas the other lying surface elements have not come into contact with the liquid, one is also in the medical hygienic cleaning given when the bed surface element that is contaminated is cleaned. The not polluted Lying surface elements do not require cleaning. In contrast to The state of the art results in a considerable time and work advantage. There is also a much improved handling. Especially from the point of view that cleaning is now possible by a single operator is an advantage.

An exchange of individual lying surface elements is also considerably easier represents the complete change of an entire slatted frame or mesh. Thus, the configuration according to the invention enables individual lying surface elements removed and replaced with replacement elements. Such one Approach is particularly useful if, for example, a quick one Restoration and use of a dirty bed cleaning of the affected surface element not on site but in separate Premises to be made. In this case it can be contaminated Lying surface element or the contaminated lying surface elements on simple Way removed from the respective bed frame section and by a hygienically perfect cleaned lying surface element or lying surface elements are replaced. The lying surface element to be cleaned or the lying surface elements to be cleaned can then be separated from the bed from which they originate, to be cleaned, during which the respective bed is already in place is prepared for use again.

The above-described exchange of individual lying surface elements for the purpose of Cleaning also has the advantage that lying surface elements to be cleaned are not are to be cleaned by hand by appropriate operating personnel instead can, for example, all bed surface elements to be cleaned throughout the hospital collected at a central location and using an automatic cleaning device to be cleaned. This is not only advantageous from an ecological point of view, Such cleaning is also carried out much more precisely and requires a comparatively large amount lower personnel costs.

As already stated above, the above-described lying surface elements have a large number of individual spring-elastic elements on the mattress support side on, which ensures that lying comfort is not solely due to the mattress is evened out, but instead a lying area is created, which corresponds to the lying position or the weight of the person lying in bed creates an elastic balance and thus the possibility of a comfortable and especially offers lying or sitting position appropriate for illness or care. The single ones Lying surface elements are with the associated spring-elastic Elements connected in such a way that a common cleaning of both the lying surface elements as well as the resilient elements is possible. For a hygienic It is therefore not necessary to clean the resilient elements to be removed from the respective lying surface element.

Overall, the bed construction according to the invention thus becomes a particular one bed suitable for the sick and / or nursing bed area made the highest due to the arrangement of resilient elements Lying comfort guaranteed, but also as Follow the design of the individual lying surface elements a simple and easy cleaning to be carried out.

According to a further feature of the invention, it is provided that the lying surface element has at least one receiving area on the bed frame side in the assembled state of the bed for a twist and / or slide-proof Arrangement of the lying surface element corresponding to the respective bed frame section trained partial areas of the respective bed frame section. This advantageous embodiment of the invention enables fast Installation and removal of the lying surface elements. These can be done easily removed from the respective bed frame section and also reinserted, whereby through the bed frame-side receiving areas into which Correspondingly designed sub-areas of the respective bed frame section protrude, it is ensured that an unwanted twisting or moving of the lying surface element is prevented. According to an embodiment For example, the respective bed frame section can be oriented upwards Have bolts which protrude into bores formed in the lying surface element. As an alternative to this, the lying surface element can also have receiving areas have, which correspond to those forming the bed frame section Profile parts are formed so that the bed surface element like a kind of insert can be introduced into the respective bed frame section. This too is advantageously a rotation and / or displacement-safe arrangement of the Lying surface element reached. Basically, gravity is sufficient to a corresponding lying surface element in the respective bed frame section to arrange, nevertheless, for additional securing of the respective lying surface element further locking devices may be provided. Therefor additional fasteners such as are particularly suitable Screws, locking pins or quick snap locks.

There is preferably one lying surface element for each individual bed frame section provided so that the total number of available Bed frame sections equal to the number of bed surface elements used is. Each of the individual lying surface elements is on the respective bed frame section can be arranged individually and can be independent of the other Removed lying surface elements and by another lying surface element be replaced. Particularly with regard to the hygienic cleaning of the This is an advantage for the lying surface element because it enables quick replacement of the individual lying surface elements so that a dirty Removed lying surface element and by a hygienically perfect lying surface element can be replaced. The removed lying surface element can then undergo appropriate cleaning.

According to a further feature of the invention, it is provided that the lying surface element is essentially plate-shaped. Such a design Lying surface element can be handled easily by the operating personnel become. In the sense of a quick connection, such a lying surface element can on each end with additional quick snap fasteners be provided in corresponding recesses on the respective Intervene in the bed frame section. This way it becomes a very straightforward and exchange of lying surface elements that can also be handled by only one operator possible. The lying surface element can be used for improved handling also be equipped with a handle.

Depending on the design of the bed frame, several can be independent of each other in their position adjustable bed frame sections may be provided. Are common, for example three or four bed frame sections, being in the case of three bed frame sections a bed frame section for the head area, a bed frame section for the foot area and a bed frame section for the middle area is provided between the head and foot. For each of these individual bed frame sections a respective lying surface element is provided. Now with one Exchange of the individual lying surface elements a confusion of, for example The individual can avoid head and foot reclining elements Lying surface elements can be provided with corresponding markings make it impossible for a lying surface element designed per se for the foot area is accidentally placed in the head area of the bed frame.

According to a further feature of the invention, it is provided that the lying surface elements Have reinforcing and / or stiffening ribs. This configuration is particularly useful when designing large-area lying surface elements an advantage because it provides additional stabilization and therefore also a improved lying comfort is achieved.

According to a further feature of the invention, the lying surface element has a circumferential side wall. On the one hand, this creates a lateral fixation one mattress placed on the lying surface elements reached, on the other offers such a lying surface element depending on the inclination improved fluid intake, so compared to one essentially plate-shaped lying surface element a larger amount of liquid can be included.

According to a further feature of the invention, the lying surface element has a surface Ventilation recesses. The design of such recesses is especially with regard to the ventilation of the bed mattress advantageous. An unnecessarily frequent transfer of the patient as a result of one repeated mattress changes can thus be avoided.

According to a further feature of the invention it is provided that several recesses a common row are arranged side by side, wherein in the longitudinal direction of the lying surface element of each row of recesses a receiving area for receiving the resilient elements is subordinate. With this configuration according to the invention, on the one hand a secure positioning of the mattress is guaranteed, on the other hand a Ventilation of the mattress ensured. The between the lying surface elements and mattress resilient elements ensure that the mattress is arranged at a distance from the respective lying surface element.

An air gap therefore forms between the mattress and the lying surface elements. This air gap is above the beund formed in the lying surface elements Ventilation recesses with the ambient air of the bed in direct Contact. Thus, there is a common air exchange between the ambient air and the air between the lying surface elements and the mattress is ensured. This advantageously brings about a volume-rich, constant ventilation the bottom of the mattress.

According to a further feature of the invention it is provided that the loading and Breakthroughs forming ventilation openings form a liquid retention collar exhibit. On the one hand, this causes the lying surface element to stabilize, on the other hand, the design of such a collar ensures that unwanted leaked fluids with the bed surface elements come into contact, not unintentionally through the ventilation openings step out and onto the floor below the bed drops. Rather, the retention collar ensures that liquids are as in Kind of a gutter and when cleaning the lying surface element can be completely and completely disposed of. Especially from hygienic For reasons, this configuration represents an improvement over the state of the Technology.

According to a further feature of the invention, the receiving area has a Plenty of resilient elements arranged in a row next to each other are. This configuration results in an overall symmetrical arrangement of the individual resilient elements, so that an overall symmetrical Feather comfort, d. H. Lying comfort is guaranteed. Depending on the choice of the individual resilient elements or depending on the number of elements used can be achieved a comfortable lying adapted to different wishes.

According to a further feature of the invention it is provided that both the Lying surface elements by means of corresponding quick fasteners on the respective Bed frame sections can be arranged so that the individual spring-elastic elements preferably quickly detachable on the respective lying surface element are arranged. On the one hand, this enables rapid expansion, for example for cleaning purposes, as well as the possibility of combined Use different elastic elements together with a common bed surface element, which gives the opportunity to to create an individual lying comfort.

According to a further advantageous proposal of the invention, it is provided that provide the lying surface element with a large number of elastic spring elements is, with several spring elements in the longitudinal direction and / or transverse direction of the lying surface element arranged side by side forming a common row are. This measure also makes it appear symmetrical overall Spring comfort achieved, which ensures a correspondingly good lying comfort. Depending on the individual user requirements, individual rows of spring elements can different spring elements exist, for example with regard to distinguish their spring stiffness. In this way, a very precisely adjustable Realize individual lying comfort.

As an alternative to the individual arrangement of different spring elements, in particular in connection with the use of a trained with side walls Lying surface element, the use of spring elements can be provided according to a further advantageous proposal of the invention mat-like with each other are combined. It is therefore proposed to use several spring elements to combine with each other to form mat-like inserts. These can then be clicked on the respective lying surface element can be placed. Especially related with lying surface elements with side walls is suitable the use of mat-like spring elements, as these by Find a secure hold on the side walls. This will cause unwanted slipping of the individual spring elements effectively prevented. Likewise, is also combined the use of mat-like pads Spring elements with a plate-shaped lying surface element possible. In this case, however, the spring elements are at least mat areas to connect to the lying surface element by means of additional fastening elements. The advantage of having several resilient elements in a mat-like attachment Combining them with each other essentially means that they can be exchanged quickly founded. In contrast to the fastening of every single element it is when using spring elements combined with each other in a mat-like manner not necessary, each individual spring element separately on the respective lying surface element to attach, rather the mat-like design is sufficient Attach the attachment to yourself. There is only one attachment point for this basically sufficient.

According to a further advantageous proposal of the invention, it is provided that the resilient element is constructed in the manner of a leaf spring and has a connecting area, a support area and a connecting area with has the spring element area coupling the support area. The connection area is used to attach the leaf spring to the respective lying surface element. For this purpose it can be provided, for example, that the connection area has a receptacle in the form of a through hole through a fastener, for example a screw, for fastening can be guided and screwed to the respective lying surface element. Likewise it is also conceivable that the connection area has quick snap elements, in corresponding recesses or on corresponding projections, which are formed on the respective lying surface element, inserted or plugged in become. The contact area of the leaf spring is used to accommodate the Bed mattress to be inserted. With the arrangement of a variety of leaf springs a flat support area is created, which is the mattress to be inserted takes up the entire area. Between the connection area and the support area a spring element area is formed. This spring element area causes the support area to be resilient relative to the connection area can move, which ultimately the resilient absorption of the bed mattress is realized. The spring element area is preferably made of at least formed a spring means that has a predeterminable spring stiffness. Also other configurations of the resilient element are conceivable, for example can the connection area, the spring element area and the Support area be formed in one piece, the only thing that matters is that by the spring-elastic element on a spring-elastic arrangement of the bed mattress the lying surface elements is made possible. Because only through the intermediate order spring-elastic elements between bed mattress and the respective lying surface elements is the formation of an improved lying comfort possible is not only due to the spring elasticity of the mattress itself. Also opened as already explained above, the intermediate arrangement of a multitude of different ones Spring elements the possibility to set an individual lying comfort.

According to a further feature of the invention, the spring element area of several essentially elongated, star-shaped arranged Spring means. In particular, this type of design is a sick or. easy-care lying comfort created.

According to a further feature of the invention, there are several resilient elements with the same and / or different spring stiffness as required Can be combined with each other according to the modular principle and with the lying surface element connectable. This is the individualization already mentioned of lying comfort realized, especially in relation to the modular principle a combination of many different elements is possible.

The resilient elements preferably consist of an acidic or alkaline-acting liquids insensitive plastic. On the one hand this enables hygienic cleaning, on the other hand you can use Appropriate injection molding techniques are used to form plastic elements fully meet the requirements described above.

1 shows a schematic representation of a bed 1 according to the invention. This bed consists of a bed frame 2 and a bed attachment 3. Bed frame 2 and bed attachment 3 are coupled to one another via a height adjustment device 4 (see Fig. 2). By means of the height adjustment device 4, the bed attachment 3 can be in its Height can be moved relative to the bed frame 2. The height adjustment device exists in detail 4 via lifting means and drive means, not shown in this figure. To enable the patient lying in bed without strangers Helping to adjust the height of the bed attachment 3 is the height adjustment device 4 operated by a remote control. The height adjustment device 4 not only enables a parallel movement of the bed attachment 3 in relation to the ground, also is the setting of an angle of inclination possible so that the bed cap 3 within the stroke limits of the height adjustment device 4 can control any position.

The bed frame 2 consists of a bed frame 5 and possibly as extensions trained support legs 6. Bed frame 5 and the support legs 6 are such designed that the permissible total weight is at least 200 kg, which equate to the fact that the permissible patient weight is at least 130 to Is 140 kg. On the bottom side, the bed frame frame 5 has a total of four Idler rollers 7. The idler rollers 7 are made of both their transverse and their The castors are rotatably mounted on the vertical axis and allow a little effort Moving as well as good bed maneuverability.

The bed attachment 3 preferably consists of a bed frame 8 and the Side panels delimiting the sleeping area. A front part 9 is provided Rear part 10 and one side part 11 for each long side of the bed. The side parts 11 can preferably be constructed in a grid-like manner and from at least two spars 12 arranged one above the other can be formed. The spars 12 are in accordance with a preferred embodiment at least on one long side of the Bed releasably arranged so that the spars at least for getting in and out are temporarily removable from their recording.

The bed frame 8 consists of several bed frame sections and an adjusting device. This is shown most clearly in FIG. 2. Preferably, the Bed frame over a total of four bed frame sections. These are divided into one Head bed frame section 13, a foot bed frame section 14, one Thigh bed frame section 15 and a middle bed frame section 16. The individual bed frame sections are pivotable and relative to each other movably arranged. This is realized by the adjusting device 17 which the individual bed frame sections are connected to each other. preferably, the adjusting device 17 is designed as a linkage and over corresponding levers can be operated from the outside.

Each of the bed frame sections 13, 14, 15 or 16 described above is with a Lying surface element 18 provided. The lying surface element preferably consists 18 made of deep-drawn plastic and has essentially the shape a plate on. The lying surface element 18 serves to accommodate a large number spring-elastic elements 19, which in turn are not shown in the figure Pick up bed mattress. This relationship can be seen most clearly in FIG. 3 become.

The lying surface elements 18 each have recesses 20 that the patient Vent the mattress carried by the spring elements 19.

As in particular the FIGS. 3 and 4, there are several findings Venting recesses 20 form a common row next to each other arranged, each in the longitudinal direction 21 of the lying surface element 18 Row of recesses 20 a receiving area 22 for receiving the resilient Elements 19 is upstream and downstream. In this way, arise crosswise rows formed in the longitudinal direction 21 of the lying surface element 18, wherein alternating rows with spring elements 19 or rows with ventilation openings 20 are provided. According to a further embodiment can be provided that the plurality of recesses 20 in a row to one Total recess are combined. Regardless of whether there are several individual recesses 19 or an overall recess are provided, preferably the recesses have a circumferential liquid retention collar 23. This retaining collar 23 is used to hold liquids that are on the Distribute lying surface element 18 to the extent that it is not covered by the Drops 20 drip through the ground.

For the rotationally and displaceably arranged arrangement of the lying surface element 18 points this has a receiving area 28 on the bed frame side, which corresponds trained partial areas of the respective bed frame section. In the 4 are the corresponding sub-areas the bed frame sections delimiting profile parts 30 themselves. The lying surface element 18 is thus designed such that a receiving area on the bed frame side 28 is provided, in which the profile parts 30 of the respective bed frame section protrude exactly. For ready-to-use assembly of the bed it is therefore sufficient that the lying surface element 18 on the bed frame section hang up so that the profile parts 30 within the receiving area 28 come to rest. The weight of the lying surface element 18 is sufficient to ensure a secure arrangement of the lying surface element 18. As a result of the arrangement of the profile parts 30 within the lying surface element 18 trained receiving area 28 is also a rotation and displacement Arrangement of the lying surface element 18 ensured. For an additional Fixing the position of the lying surface element 18 can also further security measures be provided, such as additional fasteners, the lying surface element 18 on the profile parts 30 of the bed frame section fix. Screws, bolts and locking pins are particularly suitable for this as well as quick snap closures.

In the preferred embodiment shown in FIG. 5, the elastic are Elements 19 constructed in the manner of a leaf spring and have a connecting area 24, a support area 25 and a connecting area 24 with the support area 25 coupling spring element area 26. The connection area 24 is used for the detachable arrangement of the individual leaf springs on the respective lying surface element 18. For this purpose, appropriate fastening means, such as B. screws, rivets or clip elements can be used. The Support area 25 of the spring elements 19 serves to accommodate the in the figures not shown mattress. As shown in the figures, a variety of Spring elements 19 according to the modular principle both in the longitudinal direction 20 and also in the transverse direction 29 of the lying surface element 18 forming rows next to one another arranged, this creates a flat mattress holder.

The support area 25 and the connection area 24 of the spring element 19 are coupled together by the spring element region 26. This will create a Spring-elastic storage of the support areas 25 generated, which ultimately a lying or nursing comfort is adjusted. In particular, this can Fig. 6 are removed. The spring element area 26 consists of several essentially elongated, star-shaped spring means 27. These spring means 27 can have a different spring stiffness, so that not only have different spring stiffness spring elements 19 can be combined individually, but that there is also the possibility of a spring element 18 with regard to its spring stiffness set so precisely that a "left" -tilting spring characteristic differs from tipping to the right. In this way, for example a suspension comfort pointing away from the inside of the bed can be set, so that the formation of a "bed" can be counteracted. The difference to conventional lying surface elements, such as. B. the slatted frame, allows Use of the above-described spring elements 19 a selective effect and therefore also adjustable spring comfort. Compared to conventional ones Slatted frames therefore result in a much improved setting option with regard to of lying and sitting comfort. This is further expanded by the fact that as described above, not only different spring elements 19 with one and the same Lying surface element 18 can be combined, but that also individual spring means 27 configured differently within a spring element 19 could be.

According to an alternative embodiment, a plurality of spring elements 19 can be be combined like a mat. These trained spring mats can then in the same way on the respective lying surface element 18 to be ordered. However, it is no longer necessary to use each spring element 19 to attach to the respective lying surface element 18, sufficient is the fixed arrangement of the spring element mat itself, with which all the spring element mat comprising spring elements securely on the respective Lying surface element 18 are arranged. The use of spring element mats is This is particularly advantageous if the lying surface element 18 has a like Side walls provided lying surface element is formed, the supporting Act. These side walls then prevent the spring element mats from slipping, so that on a separate attachment to the respective lying surface element 18 can be dispensed with.
