Description

[Technical Field]

[0001] [CROSS-REFERENCE TO RELATED APPLICATIONS] The present invention relates generally to the field of reclining and / or sleeping furniture, and in particular to an at least regionally deformable and / or adjustable base element for reclining furniture, as well as to reclining furniture having such a base element and a mattress. [Background technology]

[0002] Reclining furniture has been used for quite some time as a base and / or lying surface for users. Reclining furniture is constantly undergoing further development, particularly in terms of user comfort and ergonomic lying for the user. Reclining furniture is usually adapted in this case to special requirements.

[0003] Therefore, outdoor reclining furniture exists, such as in the form of garden furniture, which typically provide a foam pad or cushion for the user as a lying surface. Such bases are often uncomfortable and do not fully meet requirements regarding comfort and ergonomics of lying down. In addition, such reclining furniture typically has only a limited range of adjustment. As a result, the user is given only a few options for changing their reclining position.

[0004] Furthermore, reclining furniture is used indoors in a variety of variations, such as sleeping furniture, armchairs, couches, etc. Such reclining furniture typically includes a cushion or mattress. To improve comfort, for example, a mattress can be configured so that zones, regions, and / or support areas with different firmness, compressibility, compression hardness, and / or elasticity are adjacent to each other along the length of the mattress, for example, to adapt the sinking depth of a user lying on the mattress to their body shape. This allows, for example, a user to lie on the mattress in a lateral position with their spine as straight as possible. The same applies to the supine position. In the supine position, the spine should be supported to maintain its natural S-shape. Providing multiple support areas with different firmness and / or hardness can also advantageously take into account the user's weight distribution. This can therefore ensure that the user's body is ergonomically positioned in multiple sleeping positions or postures.

[0005] Therefore, known reclining furniture is usually conceived, designed and suitable only for specific uses, such as indoor or outdoor use, etc. In addition, known reclining furniture often does not meet requirements regarding comfort, ergonomic lying, and / or suitability to individual needs. Summary of the Invention [Problem to be solved by the invention]

[0006] Embodiments of the present invention may advantageously provide an improved base element for a reclining piece of furniture, as well as an improved reclining piece of furniture. [Means for solving the problem]

[0007] This is made possible in particular by the subject matter of the independent claims. Advantageous embodiments and developments are specified in the dependent claims and in the following description.

[0008] One aspect of the present disclosure relates to a base element. The base element is configured to at least regionally and / or partially deform and / or adjust a reclining piece of furniture and / or a mattress placed or disposed thereon. For example, the base element can be configured to at least regionally support and / or deform a mattress. The base element comprises a frame element at least partially constructed from an elastically deformable material, particularly at least partially constructed from foam, viscose foam, polyurethane foam, etc. The frame element comprises a bottom surface on a first side, such as a first longitudinal side, and a second side opposite the first side. The frame element comprises a compartment on the second side. The base element further comprises an at least partially elastically deformable cover layer. The cover layer is disposed on the second side of the frame element such that the compartment is at least partially delimited, defined, covered, and / or enclosed by the cover layer. Additionally, the cover layer forms a support surface of the base element disposed opposite the bottom surface to support the mattress. The base element further comprises an adjustment device at least partially arranged and / or housed in a compartment of the frame element. The adjustment device comprises at least one drive unit and a drive mechanism coupled to the drive unit, in particular mechanically and / or electrically. The adjustment device is configured to at least regionally and / or partially deform, displace, and / or adjust the base element and / or a mattress placed thereon. The drive mechanism comprises at least two rails. The rails are arranged substantially parallel to the longitudinal axis of the base element and are spaced apart and / or interconnected parallel to the lateral axis of the base element by at least one cross member. The at least one cross member extends parallel to the lateral axis of the base element and / or transversely to the longitudinal axis of the base element. In this case, each of the at least two rails comprises at least two rail elements. The rail elements are arranged front and rear parallel to the longitudinal direction of the base element and are interconnected via at least one joint and / or joint connection.As a result, at least two rail elements of each rail are mutually displaceable, swivellable and / or tiltable via at least one drive.

[0009] By displacing and / or pivoting the rail elements of the rail, the reclining furniture, the mattress and / or the base element can be deformed, deformed and moved, in particular so as to allow for variable and / or variably setting of lying positions for the user.

[0010] The adjustment device may be protectively housed within the frame element and may allow adjustment or deformation of the base element, thereby allowing one or more portions and / or areas (or reclining areas) of a mattress and / or reclining furniture placed thereon to be adjusted as needed, as described in more detail below.

[0011] In the context of this disclosure, reclining furniture may refer to any type of reclining furniture, such as sleeping furniture, armchair, lounger, bed (furniture), bed, couch, etc.

[0012] In principle, the frame elements can be any structure made partly or completely from an elastically deformable material, in particular they can be made partly or completely from foam, viscose foam, polyurethane foam, etc.

[0013] The frame element and the compartment configured therein can form a frame for the adjustment device. For example, the frame element and / or the compartment can be configured such that the adjustment device is surrounded and / or enclosed by the frame element on the bottom and all four sides. The adjustment device can thus be housed and / or positioned integrally with the frame element. This can protect the adjustment device from mechanical damage and / or further environmental influences, such as the ingress of water or moisture.

[0014] In the context of this disclosure, a compartment can refer to a chamber, space, opening, cutout, and / or recess. The compartment has substantially the same width, height, and depth as the adjusting device, so that the adjusting device can be considered to be held on one or more sides of the frame element and / or within the compartment. In this way, movement of the adjusting device can be kept to a minimum. The adjusting device can be cushioned and covered and / or protected by the frame element.

[0015] The first side of the frame element comprises a bottom surface that can serve to rest and / or support the base element and / or the reclining furniture piece thereon.

[0016] The adjustment device may be a motorized adjustment structure or arrangement configured to adjust, move, pivot, and displace at least two rail elements of at least one of the at least two rails relative to one another via at least one drive and at least one drive mechanism. In this case, in particular, the rail elements of one rail, the rails, or each rail may be displaced about an axis parallel to the transverse axis of the base element and / or about an axis parallel to at least one crosspiece of the base element and / or about an axis transverse to the longitudinal axis of the base element. Thus, a region of the base element between opposing rail elements of a pair of rails (in the transverse direction of the base element) may be displaced and / or adjusted relative to a further region of the base element, such as between further rail elements of an opposing rail pair (in the transverse direction of the base element), for example, about an axis parallel to the transverse axis of the base element.

[0017] At least two rails of the adjusting device, together with at least one cross member, can form a structure or shape, such as an H and / or a ladder. Two legs of the H can be formed by at least two rails. The position of the cross member is optional.

[0018] The drive can in principle be any type of electric drive and / or electric motor. In this case, the drive can be supplied with energy via an energy storage device and / or a power cable. Supply via solar cells, photovoltaics and / or energy harvesting is also conceivable.

[0019] Alternatively or additionally, the drive unit can be inductively supplied with electrical energy, for example, the base element can comprise one or more inductive receivers, such as one or more receiving coils, that can be inductively coupled to an external inductive supply.

[0020] The cover layer can generally refer to a layer of elastically deformable material that can be placed on the frame element. In this case, the cover layer can be made of the same material as the frame element or a different material. In particular, the cover layer can be made of a foam material, foam, viscose foam, polyurethane foam, etc.

[0021] The cover layer can be dimensioned and configured to at least substantially define and / or close the compartment. In this case, substantially can mean, for example, that one or more access points are provided so that a user can reach the compartment of the adjusting device. However, it is also possible for the compartment to be completely defined and / or closed by the cover layer on the second side of the frame element. Similarly, the compartment can be defined by the frame element and the cover layer. The adjusting device can generally be protected from external influences or impacts by the cover layer.

[0022] The cover layer may in particular have a base surface that is substantially identical to the frame element and / or a contour that is substantially identical to the frame element, so that the cover layer can be placed, positioned and / or supported on the frame element over substantially its entire surface and / or flush with it.

[0023] In this case, the thickness or strength of the cover layer may be constant or variable across its surface, for example the cover layer in the area of ​​the compartment may have a different thickness than other areas of the cover layer, such as being thicker.

[0024] According to one embodiment, the adjusting device for the base element further comprises a control unit configured to activate and / or control the drive. In particular, the control unit can be configured to adjust, control and / or monitor the rotation direction and / or rotation speed of the drive. For example, this can be used to adjust and / or control the direction and / or speed of movement of adjusting, moving, pivoting and / or displacing the rail element, the rail, the base element and / or a mattress placed thereon.

[0025] The control unit can generally be a control circuit, a controller, and / or a control component. The control unit can, for example, comprise one or more microcontrollers and / or processors. In this case, the control unit can be arranged together with the drive and / or further components in a single housing, or in a separate housing. The control unit can be connected to the drive of the adjustment device wirelessly or by wire. Alternatively or additionally, the control unit can be integrated into and / or arranged on one of the rails. In particular, if the base element or at least part of it is designed to be waterproof or water-resistant, the communication connection between the drive and the control unit can be established via a cable.

[0026] Optionally, the control unit may be provided with a housing, in particular a waterproof and / or hermetically sealed housing, which may protect the control unit and / or its electronics from environmental influences, such as, for example, water, moisture or mechanical influences.

[0027] The adjusting device and / or the control unit may optionally comprise a data memory in which one or more predefined positions of the rail elements relative to one another can be stored.

[0028] According to one embodiment, the adjusting device of the base element is at least partially waterproof and / or hermetically sealed. All or some of the components or elements of the adjusting device, in particular the drive and / or the drive mechanism, can be waterproof. In particular, any connections between the control unit and the drive, between the drive and the drive mechanism, and / or between the drive and the optional energy supply can be waterproof. Designing the adjusting device to be at least partially waterproof allows the base element to be used in particular in open or damp environments or environments with stressful ambient influences, such as, for example, swimming pools, beaches, lounges, clubs, public institutions, etc.

[0029] For example, one or more optionally present cables, such as a power cable and / or a cable between the drive and the control unit, may be insulated with a protective waterproof sheath. Alternatively or additionally, the cable connections may be configured to be waterproof.

[0030] Alternatively or additionally, one or more cable bushings between the components of the adjusting device and / or between the components of the base element can be configured to be waterproof. For example, for this purpose, at least one sealing element can be provided on at least one cable bushing that hermetically surrounds the cable guided through the cable bushing along at least a portion of the cable's circumference. Alternatively or additionally, one or more cable bushings can be mechanically reinforced, for example by means of eyelets.

[0031] Alternatively or additionally, the control unit, the control circuitry, the drive and / or the drive mechanism may be housed in one or more housings in a protected, in particular waterproof, manner.

[0032] It is possible to arrange each component of the adjusting device, i.e., mechanical or electronic, in a separate housing, or to arrange several components in a common housing. In this case, such a housing may be multi-piece or one-piece. For example, in the case of a multi-piece housing, different parts or pieces of the housing may be connected to each other using waterproof seals. Cable bushings, including one or more seals, may also be injection molded, cast, and / or glued to each housing.

[0033] According to one embodiment, the regulating device further comprises one or more energy storage devices configured to at least partially supply the regulating device with electrical energy. The at least one energy storage device can essentially be any energy storage device, for example, an accumulator, a battery, a capacitor, etc. The at least one energy storage device can in particular be designed to supply the regulating device with electrical energy in an energy autonomous manner over a certain period of time. This allows the base element to be used flexibly in any position.

[0034] The at least one energy storage device can be characterized by one or more of the following characteristics, among others: low self-discharge, protection against short circuits, overcurrent cutoff, deep discharge protection, acoustic warning when low charge is remaining, visual indication of the charge state, LED charge indicator for indicating the charge state, fixing feet, a capacity of at least 1000 mAh, e.g., 1800 mAh, a short charging time, and a low weight (e.g., 300 to 1500 grams, especially about 500 grams). The energy storage device can be matched to the regulator with its performance specifications.

[0035] It is also possible to replace the energy storage devices as needed. At least one energy storage device can be charged, for example, via a cable. Alternatively or additionally, the energy storage device can be charged inductively, by energy harvesting, and / or by a solar cell.

[0036] For example, the base element may include one or more inductive receivers, such as one or more receiving coils, that can be inductively coupled to an external inductive supply to charge the energy storage device.

[0037] Optionally, the energy storage device may be housed in one or more housings, particularly in waterproof and / or hermetically sealed housings.

[0038] According to one embodiment, the adjustment device includes multiple drives and / or multiple drive mechanisms. For example, at least one drive and at least one drive mechanism can be provided for each of one or more pairs of rail elements of at least two rails that are laterally opposed to one another on the base element. This allows for paired pivoting and / or displacement, along with the necessary force. Thus, individual areas between opposing rail elements of a pair can be flexibly displaced relative to one another as needed. As a result, individual recumbent positions can be set. The use of multiple drives and / or drive mechanisms can increase the load-bearing capacity of the adjustment device. For example, when using one or more drives / drive mechanisms, the adjustment device can withstand loads of at least 80 kg, at least 100 kg, at least 150 kg, at least 30 kg, or more.

[0039] In this case, the adjusting device and / or the control unit are particularly configured for infinitely variable adjustment of the rail elements, the base element and / or the reclining furniture, e.g., rail elements that are longitudinally adjacent to one another and in each case connected via a joint can be swiveled (about an axis parallel to the transverse axis of the reclining furniture and / or the base element) through at least 50°, at least 60°, at least 70°, at least 80°, at least 90°, at least 120° or more.

[0040] According to one embodiment, the adjustment device comprises at least one interface and / or communication interface configured to receive and / or transmit control signals. The at least one drive is configured to deform the base element and / or a mattress placed thereon at least regionally, such as in one or more regions of the base element between laterally opposing pairs of rail elements, based on the control signal. Alternatively or additionally, the control unit is configured to control and activate the drive, set the direction of rotation, and set the rotation speed and / or angle based on the control signal.

[0041] The control signal may include and / or correlate with information regarding the rotation direction, rotation angle, height, rotation speed, position, and / or shape of the base element that the adjustment device should achieve, so that a user of the base element or a reclining piece of furniture having such a base element can, as needed and individually, transform a mattress that can be placed on the base element according to the user's wishes.

[0042] The interface can be essentially any interface that allows a user to send or receive control signals in any way. In this case, at least one interface can be a wired or wireless connection. For example, at least one interface can be configured to connect a control device, a smartphone, a tablet, a PC, a server, etc. The at least one interface can establish, for example, a bus connection, a cellular connection, a WLAN connection, an Internet connection, a Bluetooth® connection, a wireless connection, an optical connection, a cable connection, or any other connection(s) with one or more further devices. The interface can in particular be configured to receive control signals from the control device and / or from a control unit of the base element or the reclining furniture.

[0043] According to one embodiment, at least one interface is a wireless interface configured to receive and / or transmit control signals wirelessly. For example, the interface may be configured for communication with a smartphone or similar data processing device, such as a tablet. The adjustment device may be controlled and / or operated via an app installed thereon.

[0044] According to one embodiment, the base element further comprises an operating device configured to transmit and / or receive control signals wirelessly and / or via a cable to the adjusting device, to the at least one drive and / or to a control unit of the adjusting device. The operating device can function as a kind of wired and / or wireless remote control, allowing a user to operate and / or actuate the adjusting device in a comfortable manner. In particular, if the base element or at least a part thereof is waterproof or water-resistant, the communication connection between the operating device as well as the adjusting device and the at least one drive and / or control unit can be established via a cable.

[0045] The operating device can basically be any device that the user can use to send or receive control signals. It can be a smartphone, a tablet, a remote control, etc. The control signals can be sent from the user, for example, by pressing a button, via gesture control, via a display, or via voice commands. The operating device can be connected to the base element via a cable and / or wirelessly. In this case, the connection to the operating device can be waterproof. The operating device itself can also be waterproof. Alternatively or additionally, the control signals can be sent or received wirelessly, for example via a mobile radio interface of the operating device. Remote control via the Internet, such as via an app or web interface, is also conceivable.

[0046] According to one embodiment, the drive mechanism coupled to the at least one drive unit comprises a cable tensioning mechanism and / or a gear mechanism. In this case, the drive mechanism can be at least partially, particularly completely, housed, integrated, and / or arranged in one or more rail elements and / or at least one crosspiece, thereby enabling a compact design and protection of the adjusting device. Alternatively or additionally, the drive mechanism can be at least partially housed in the housing.

[0047] The rails and / or rail elements may be made from sturdy materials such as plastic, fiber-reinforced plastic, metal, wood, among others.

[0048] According to one embodiment, at least one longitudinal support strut is disposed in each of at least two rails to extend each rail. For example, the longitudinal support struts can be disposed at one or both ends of the rails, such as the head and / or foot ends of each rail. The longitudinal support struts can be made of the same or a different material as the rails, such as plastic, fiber-reinforced plastic, metal, wood, etc. A wooden construction can be particularly advantageous.

[0049] The surface of one or more areas of the base element and / or of the mattress placed thereon can advantageously be extended in the longitudinal direction of the base element via the longitudinal support struts, since in each case the areas can be displaced between pairs of opposing longitudinal support struts in the transverse direction.

[0050] In this case, the longitudinal support struts can be mechanically connected and / or coupled to each rail or each rail element. Plug-in, press-fit and / or snap-in connections are possible. However, other connections are also possible, such as connections by bolts, screws and / or adhesive.

[0051] According to one embodiment, an intermediate layer is disposed between each rail and the frame element, the bottom surface of the frame element, and / or the cover layer. As a result, the rail and the frame element, the bottom surface, and / or the cover layer are separated from one another by the intermediate layer. In this case, the intermediate layer can comprise any material, such as a textile material, fabric, cloth, synthetic material, plastic, or other material. The intermediate layer advantageously protects the frame element from the effects of the rail. For example, if the rail is made of wood and the frame element is made of foam, the foam may be damaged, e.g., become porous, when it comes into contact with the wood. The intermediate layer effectively prevents such material damage.

[0052] In this case, the intermediate layer can refer to a separate layer or layers of material. Alternatively or additionally, the intermediate layer can refer to an outer layer of material, paint, and / or coating of the rail, frame element, bottom surface of the frame element, and / or cover layer. For example, the intermediate layer can be applied to the frame element, rail, cover layer, and / or bottom surface in the form of paint, etc. Alternatively or additionally, the intermediate layer can refer to an adhesive layer. For example, the rail can be at least partially adhered to the frame element. The adhesion between the frame element and the rail can constitute the intermediate layer.

[0053] According to one embodiment, the longitudinal support struts arranged on each of the two rails are interconnected and / or spaced apart via at least one transverse support strut, so that the area between the opposing longitudinal support struts in a transverse pair can be supported by at least one transverse support strut. Multiple transverse support struts can also be provided for each area.

[0054] According to one embodiment, at least one drive unit is arranged on one of the at least two rails and is connected to at least one additional rail arranged oppositely via at least one shaft. For example, the drive unit can include a shaft. At least one drive unit, such as a gear mechanism and / or a cable tensioning mechanism, can be arranged on each rail. The drive unit can activate one of the drive units on one of the rails and transmit the rotation of the drive unit to the drive unit on the oppositely arranged rail via the shaft. In this way, two rails or rail elements of two rails can be moved via only one motor or drive unit. This allows, in particular, a compact and lightweight design of the base element.

[0055] According to one embodiment, each of the at least two rails comprises at least three rail elements, which are arranged parallel to one another in the longitudinal direction and connected to one another via at least one joint. As a result, the base element is deformable, movable, and / or displaceable in at least three partial regions. The at least three partial regions may be formed between pairs of laterally opposing rail elements. One or two further regions may also be displaceable in this way at one or both front ends of the base element. However, no rails may be arranged there.

[0056] According to one embodiment, the base element further comprises at least one base cover and / or intermediate cover, which at least partially, in particular completely, surrounds the base element and is particularly configured to prevent a mattress placed on the base element from slipping. The base cover can be made of any material and / or fabric, in particular natural fibers, synthetic fibers or a mixture thereof. The base cover can also serve to protect the base element.

[0057] Optionally, the base cover can be at least partially waterproof, e.g., on the bottom, sides, and / or top. For example, the base cover can include one or more water-repellent, water-resistant, and / or waterproof layers, such as made of a rubber material, latex, a polymer-based material, or other suitable material.

[0058] According to one embodiment, the base cover is at least partially made of a rubber-like material. Alternatively or additionally, the base cover is at least partially rubberized. Alternatively or additionally, the base cover is at least partially made of latex. In particular, the upper surface on which the mattress can be placed and / or the underside on which the base element rests on a bottom or support surface can be at least partially rubberized, coated, and / or provided with latex to prevent the mattress from slipping and / or to prevent or resist the ingress of water or moisture.

[0059] According to one embodiment, the base cover comprises an at least partially circumferential fastener, in particular a slide fastener, which can be opened and closed to insert and / or remove the base element. Optionally, the slide fastener can be at least partially waterproof to prevent or resist the ingress of water or moisture.

[0060] A further aspect of the present disclosure relates to a reclining furniture piece having a base element as described above and below. All disclosures made above and below regarding the base element apply equally to the reclining furniture piece, and vice versa. The reclining furniture piece further includes a mattress. The mattress is placed and / or disposed on a cover layer of the base element by a first side. As a result, the mattress is at least regionally deformable, displaceable, and / or adjustable by at least regionally deforming the base element using an adjustment device. The mattress has a second side opposite the first side. The second side constitutes a lying surface for the reclining furniture piece. In this case, the mattress can be placed and / or disposed on the base element such that the mattress is moved and / or displaced in correspondence with, coincident with, and / or in response to movement of the base element.

[0061] In this way, one or more mattress regions or reclining regions, which may be positioned between pairs of laterally opposing rail elements and / or at one or both head ends, can be individually adapted and / or adjusted, particularly in terms of position, relative position, angle between the regions, and / or height, in a stepless manner. This provides a significant sense of comfort for the user, as they can change their position as needed. This also increases the versatility of the reclining furniture. Therefore, the reclining furniture can be used equally advantageously for indoor and outdoor purposes. The reclining furniture can also be variably adapted to special requirements, such as as a lounge chair, pool chair, bed, garden furniture, couch, sleeping furniture, etc.

[0062] Furthermore, the modular design of the reclining furniture advantageously allows components such as the base element and the mattress to be transported separately, which in turn significantly simplifies delivery to the customer, return shipping, and transportation by the user to different locations. The range of uses for the reclining furniture can also be further expanded, as different types of mattresses can be used, etc.

[0063] According to one embodiment, the reclining furniture further comprises at least one reclining furniture cover at least partially, in particular completely, enclosing the base element and the mattress, which can advantageously be used to mechanically hold the mattress and the base element together to prevent the mattress from sliding on the base element.

[0064] Alternatively or additionally, the base element and the mattress may be interconnected using snaps, Velcro fasteners, slide fasteners, and / or straps positioned at least in part on the upper side of the base element and / or base cover.

[0065] The reclining furniture may be provided with one or more reclining furniture covers, in particular a first reclining furniture cover configured as a mattress cover and a second reclining furniture cover configured as an outer cover.

[0066] Optionally, a further intermediate cover may be provided between the mattress cover and the outer cover. Alternatively or additionally, a further outer cover may be stretched over the outer cover.

[0067] One or more covers, in particular the base cover, one or more reclining furniture covers, mattress cover, outer cover, further outer cover, and / or one or more intermediate covers, can be at least partially rubberized, coated, and / or comprise latex. In other words, one or more covers, in particular the base cover, reclining furniture covers, mattress cover, outer cover, further outer cover, and / or one or more intermediate covers, can be configured to be waterproof, water-repellent, and / or water-resistant.

[0068] Optionally, one or more covers, in particular the base cover, the reclining furniture cover, the mattress cover, the outer cover, the further outer cover, and / or one or more intermediate covers, may be provided with an at least partially circumferential fastener, in particular a slide fastener, which may optionally be at least partially waterproof to prevent or resist the ingress of water or moisture.

[0069] According to one embodiment, the reclining furniture cover comprises an at least partially circumferential fastener, in particular a slide fastener, which can be opened and closed to insert and / or remove the mattress and / or base element of the reclining furniture. Optionally, the fastener can be at least partially waterproof.

[0070] According to one embodiment, at least one reclining furniture cover is configured as a mattress cover, and the mattress cover and / or the cover fabric of the mattress cover are at least partially made of spacer textiles, in particular weft-knitted spacer knit fabrics and / or warp-knitted spacer knit fabrics, which advantageously allow air and moisture exchange.

[0071] According to one embodiment, the mattress cover comprises a cover fabric having at least one upper layer and one lower layer, the upper and lower layers being at least partially overlapping one another, at least the upper layer of the cover fabric being made of a weft-knitted spacer knit fabric, for example a three-dimensional weft-knitted spacer knit fabric, and the plurality of recesses are formed on at least the outer side of the upper layer opposite the lower layer.

[0072] In this case, the lower layer can be substantially closed and / or knitted in a closed state. Thus, the recess can form a perforation or opening in the upper layer. Thus, the recess can be bounded by the lower layer. Optionally, the recess can be at least partially bounded between the upper and lower layers by spacer yarns. The contour of the recess in the upper layer can be defined by the stitches of the three-dimensional weft-knitted spacer knit fabric of the upper layer.

[0073] Thus, the mattress cover takes advantage of a weft knitted spacer knit fabric, which comprises a spacer structure having stitches made from, for example, at least partially knitted monofilament or multifilament spacer yarns.

[0074] Furthermore, recesses configured on the outside can improve air circulation, breathability and / or moisture removal.

[0075] Weft-knitted spacer knit fabrics used for mattress covers differ in several respects from warp-knitted spacer knit fabrics typically used for covers. For example, warp-knitted spacer knit fabrics are typically produced on a so-called warp knitting machine. On the other hand, weft-knitted spacer knit fabrics are typically produced on a stockinette knitting machine. A further distinction is made between flat knitting machines and circular knitting machines. When producing warp-knitted spacer knits, the stitches are knitted around the warp yarns (and thus the warp knitting machine). In this case, the stitches are knitted perpendicular to each other. This knitting of the stitches around the warp yarns makes the warp-knitted spacer knit fabric stable, stiff, inelastic, and inextensible. In contrast, the stitches of a weft-knitted spacer knit fabric are not stretched around the warp yarns, and such stitches can be elastic and stretchable in both horizontal and vertical directions. Therefore, compared to warp-knitted spacer knit fabrics, weft-knitted spacer knit fabrics can be characterized, in particular, as being elastic and stretchable in both horizontal and vertical directions. In contrast, warp-knitted spacer knit fabrics can be characterized as completely inelastic and non-stretchable. Therefore, warp-knitted spacer knit fabrics are static, rigid fabric structures with little or no elasticity. Furthermore, warp-knitted spacer knit fabrics have a stiff, hard, and plastic-like feel. On the other hand, weft-knitted spacer knit fabrics can have a softer feel, similar to a textile or cloth. Furthermore, warp-knitted spacer knit fabrics typically have fiber ends protruding from the surface of the woven fabric, resulting in a scratchy or rough feel. In contrast, weft-knitted spacer knit fabrics typically have a much softer feel. This may be due to the increased elastic properties of the weft-knitted spacer knit fabric and its much finer finish compared to warp-knitted spacer knit fabrics.

[0076] Mattress covers (including protective mattress covers) can have an upper side and / or a lower side, each of which can be sized as a lying surface for a user, however, in this case the lower side only optionally provides a lying surface and does not necessarily need to be fully closed.

[0077] In the context of this disclosure, recesses formed at least on the outside of the upper layer of the cover fabric should be strictly distinguished from the stitches that may constitute the cover fabric, the lower layer, and / or the upper layer. The recesses may have larger dimensions compared to the stitches. For example, the recesses may have a cross-sectional area that is several times larger (approximately 5 to 100 times or more) than the average cross-sectional area of ​​the stitches of the cover fabric.

[0078] The cover fabric may generally be constructed of two, three, or multiple layers. In particular, the cover fabric may be made and / or constructed entirely of weft-knitted spacer knit fabric and / or three-dimensional weft-knitted spacer knit fabric.

[0079] In the case of a two-layer cover fabric, the upper and lower layers can be at least partially interconnected and / or knitted with the upper and / or lower layer yarns, for example, in a point-like manner. Alternatively or additionally, a connecting yarn can be used that can connect the upper and lower layers. In the case of a three- or multi-layer cover fabric, one or more middle layers of the cover fabric can be connected to and / or knitted with the upper and / or lower layers. Alternatively or additionally, a connecting yarn can be used here that can connect at least two layers of the cover fabric, such as the upper layer, the lower layer, and / or one or more middle layers.

[0080] Mattress covers can be produced in a simple manner, for example on large circular knitting machines operating according to the so-called three-way technology, with a high throughput in terms of time and therefore with high economic efficiency.

[0081] The recesses can be configured to open outward, i.e., toward the user, and / or have an outward-opening cross section. Therefore, the recesses can refer to openings. In this case, the recesses can generally be advantageous in terms of air exchange and moisture removal, as well as compensation for temperature fluctuations. The recesses can also increase elasticity, which provides a soft feel to the user. Additionally, this allows the cover to optimally fit the user's head or body lying on it, without the brittleness of the inelastic spacer yarns often perceived in warp-knitted spacer knit fabrics.

[0082] The recesses formed on at least the outer side of the upper layer can further provide and / or form the mesh structure of the cover fabric, i.e., the cover fabric can have a mesh structure, such as a honeycomb mesh structure, with recesses on at least the outer side.

[0083] The recesses in the mesh structure and / or cover fabric can be arranged, for example, in a regular arrangement on the outer side of the cover fabric. In other words, the recesses can be arranged regularly and / or in a regular pattern. However, irregular arrangements, for example, arrangements forming a pattern, are also contemplated.

[0084] Recesses, such as outwardly opening recesses, can be variable in terms of their geometric shape, so that their open cross-section can be configured, for example, as round, angled, oval, polygonal, elliptical, or any other shape.

[0085] For example, the recesses may be configured in a honeycomb shape. Alternatively or additionally, the recesses may have a rounded, rounded, angled, quadrangular, square, rectangular, triangular, oval, elliptical, and / or polygonal cross-section.

[0086] According to one embodiment, the upper and / or lower layers of the cover fabric are at least partially composed of natural fibers.

[0087] For example, the use of natural fibers, which can be included in and / or knitted into the weft-knitted spacer knit fabric, can improve the sustainability and / or ecology of mattress covers (hereinafter also referred to as "covers") because the natural fibers can be obtained from renewable raw materials. Natural fibers can also be characterized by high resilience and / or durability. Furthermore, natural fibers can result in a comfortable, soft feel for the user. Natural fibers can also be characterized by improved skin compatibility, breathability, and / or odor neutralization. Additionally, natural fibers can enable mattress covers to be produced more cost-effectively.

[0088] According to one embodiment, the natural fibers are animal hair fibers, wool fibers, cotton fibers, hemp fibers, eucalyptus fibers, bamboo fibers, flax fibers, wood fibers, viscose fibers, flax fibers, silk fibers, vegetable fibers, or combinations thereof. Compared to synthetic fibers, such natural fibers can be characterized by improved sustainability, odor neutrality, skin compatibility, durability, and / or robustness.

[0089] According to one embodiment, the top layer, bottom layer, and / or one or more middle layers of the cover fabric have a weight percentage of natural fibers of at least 5%, at least 10%, at least 15%, at least 20%, and / or at least 25%, for example, between 2% and 99% of the respective layer or the entire cover fabric. A weight percentage of at least 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, or 75% of natural fibers is also contemplated.

[0090] According to one embodiment, the proportion, e.g., by weight and / or volume, of natural fibers in the top layer, e.g., relative to each layer or the entire cover fabric, is greater than the proportion, e.g., by weight and / or volume, of natural fibers in the bottom layer and / or one or more middle layers. For example, the proportion in the top layer can be at least twice the corresponding proportion of natural fibers in the bottom layer and / or one or more middle layers.

[0091] According to one embodiment, the top layer consists substantially and / or nearly entirely, e.g., completely, of natural fibers, and the bottom layer and optional one or more middle layers consist substantially and / or nearly entirely, e.g., completely, of synthetic fibers.

[0092] According to one embodiment, the upper and / or lower layers of the cover fabric are at least partially composed of textured twisted yarns, in particular multifilament yarns, such as polyester, polyethylene, polyamide, polyethylene, and / or polyamide yarns, which can provide a soft and comfortable feel.

[0093] According to one embodiment, the upper and / or lower layers of the cover fabric are at least partially composed of monofilament yarns, in particular polyester yarns, smooth polyester yarns, polyethylene yarns, smooth polyethylene yarns, polyamide yarns, and / or smooth polyamide yarns. If the cover fabric is composed of monofilament yarns on the underside facing the mattress core or pillow core, the mattress core or pillow core can be easily removed or inserted.

[0094] For example, a cover fabric made of weft-knitted spacer knit fabric may be composed of at least two layers, with an upper layer forming the outer surface and a woven layer forming the inner or lower layer, preferably made of polyester fiber fabric, polyethylene fiber fabric, and / or polyamide fiber fabric.

[0095] The inner or lower layer can be, for example, a smooth woven layer, which can be jacquard-textured and / or, for example, patterned, onto which a top layer of a weft-knitted spacer knit fabric made of textured twisted yarns, in particular multifilament yarns, can be built outwards.

[0096] According to one embodiment, the cover fabric further comprises a middle layer, which is knitted at least in points and / or at least partially together with the upper and / or lower layers, and which can serve to increase the volume of the cover fabric, thereby further enhancing sleeping comfort.

[0097] According to one embodiment, the middle layer is at least partially composed of monofilament yarns, in particular polyester yarns, smooth polyester yarns, polyethylene yarns, smooth polyethylene yarns, polyamide yarns and / or smooth polyamide yarns.

[0098] According to one embodiment, the middle layer is at least partially composed of multifilament yarns, such as textured twisted multifilament yarns, such as polyester yarns, polyethylene yarns, polyamide yarns, polyethylene yarns, and / or polyamide yarns.

[0099] According to one embodiment, the middle layer is at least partially made of natural fibers, providing the advantages mentioned above with respect to natural fibers.

[0100] According to one embodiment, the recess extends at least substantially through the thickness of the upper layer and, if desired, through the thickness of the middle layer. In particular, the recess can extend completely through the thickness of the upper layer, so that the recess can constitute and / or represent, so to speak, a penetration in the upper layer.

[0101] The recesses can extend, for example, at least substantially through the entire thickness of the top layer, i.e., from the outside to or near the inner or lower layer, such as to allow optimal climate control with respect to air and moisture exchange between the two sides of the cover fabric. Additionally, the depth of the recesses can increase the softness of the top layer made of weft-knitted spacer knit fabric, thereby providing an improved feel.

[0102] The cover fabric can also be constructed with three layers: a middle layer, a co-knitted layer with the top layer, and a monofilament filler. In this case, high air and moisture permeability can simultaneously stabilize the weft-knitted spacer knit fabric and achieve increased volume, which is often desired for feel. The monofilament filler can be, for example, at least partially made of polyester, polyamide, and / or polyethylene. However, other synthetic fibers can also be used for this purpose.

[0103] In order to give the outward-facing surface or outer side of the weft-knitted spacer knit fabric a particularly smooth and pleasant feel, the surface or outer side surrounding the recess can be formed from finer stitches compared to other areas of the outer side.

[0104] According to one embodiment, the upper layer has a weight percentage of 50% to 70%, in particular 55% to 60%, of the cover fabric, which studies have shown to be particularly advantageous in terms of comfort and microclimate control.

[0105] According to one embodiment, the lower layer has a weight proportion of 20% to 30%, in particular 25% to 30%, of the cover fabric.

[0106] According to one embodiment, the middle layer has a weight proportion of 10% to 20%, in particular 15% to 20%, of the cover fabric.

[0107] When using fillers, optimum results in terms of air permeability, stability, and volume have been determined when the weight percentage of the middle layer in the cover fabric is 10% to 20%, particularly 15% to 20%.

[0108] According to one embodiment, the cover fabric has a thickness of 250 g / m 2 ~300g / m 2 This allows the cover fabric to have the required durability while at the same time allowing for ease of handling in terms of its weight during manufacture and use.

[0109] According to one embodiment, the cover fabric is rubberized, coated, and / or provided with latex on at least one side, e.g., the outer, inner, underside, and / or upper side, such as to prevent moisture and / or water ingress.

[0110] According to one embodiment, the cover fabric is configured identically on all sides, i.e., the mattress cover is configured identically on all sides, i.e., the upper side, the lower side, and any longitudinal and lateral sides that may be present. However, it is also possible in principle to configure the different sides of the cover differently.

[0111] The identical construction of all sides makes it particularly easy to manufacture. Due to the high breathability of the cover fabric, it is also possible to dispense with the ventilation bands on the lateral and longitudinal sides that are often found in known covers, especially mattress covers.

[0112] According to one embodiment, the mattress cover comprises an at least partially circumferential fastener, in particular a slide fastener, which can be opened and closed to insert or remove the mattress core and / or pillow core.To allow the insertion and removal of the mattress core or pillow core, it may be advantageous for the mattress cover to comprise an at least partially circumferential fastener, in particular a slide fastener.

[0113] Additionally, handles can be sewn onto the mattress cover to facilitate handling of the mattress and / or the mattress covered by the bed furniture.

[0114] The mattress cover may further be washable at temperatures of, for example, at least 30°C, at least 40°C, at least 50°C, at least 60°C, at least 70°C, at least 80°C, or at least 90°C.

[0115] A further aspect of the present disclosure relates to the use of a mattress cover for reclining furniture, as described above and below.

[0116] Reclining furniture with a mattress cover can be advantageous, particularly when the reclining furniture is used indoors. Alternatively or additionally, the reclining furniture can also be provided with an outer cover. The outer cover can at least partially, particularly completely, enclose the base element, the mattress, and optionally the mattress cover.

[0117] Optionally, a further outer cover can be provided which can at least partially, in particular completely, enclose the outer cover. The further outer cover can, for example, be configured similarly to a mattress cover as described above and below. By providing a further outer cover, sleeping comfort for the user can be improved and protection against water can be ensured by the underlying outer cover and / or by a further cover, in particular by a base furniture cover.

[0118] According to one embodiment, at least one reclining furniture cover is configured as an outer cover, in particular for use of the reclining furniture outdoors, the outer cover being at least partially waterproof, washable and / or thermal insulating.

[0119] According to one embodiment, the outer cover comprises silicone, rubber, polymeric material, textile material, fabric, latex, plastic, leather, synthetic leather, and / or synthetic material.

[0120] A variety of materials, colors, and textures may be considered and / or combined for the outer cover.

[0121] According to one embodiment, the outer cover is provided with an at least partially circumferential fastener, in particular a slide fastener, which can be opened and closed to insert and / or remove the mattress and / or base element of the reclining furniture. The fastener is configured to be at least partially waterproof, which can be advantageous in particular when using the reclining furniture outdoors or in harsh environments.

[0122] According to one embodiment, the reclining furniture further comprises a non-slip ply or layer disposed on the cover layer of the base element and positioned between the base element and the mattress, the non-slip ply or layer configured to secure the mattress on the base element against slippage. The non-slip ply or layer may comprise, for example, rubber, silicone, latex, etc.

[0123] According to one embodiment, the mattress comprises at least one head support region for supporting the head, at least one neck support region for supporting the neck, at least one shoulder support region for supporting the shoulders, at least one lordosis support region for supporting at least a portion of the spine, and at least one pelvic support region for supporting the pelvis of the user.

[0124] According to one embodiment, the head support region, neck support region, shoulder support region, lordosis support region, and pelvic support region have at least partially mutually different profiles on the first side and / or the second side of the mattress. Such profiles can be, for example, contours and / or structures. As a result, the individual support regions, i.e., the head support region, neck support region, shoulder support region, lordosis support region, and / or pelvic support region, differ in firmness, compression firmness, and / or hardness from one another and / or the compression firmness of the mattress (or mattress elements of the mattress) differs from one another at least regionally. The mattress can further optionally be a mattress that can provide different firmnesses and / or a reversible mattress.

[0125] For ergonomic and comfortable lying, the mattress (or each of its mattress elements) can be divided into different support regions and / or zones. In particular, the mattress can include one or more head support regions, one or more neck support regions, one or more shoulder support regions, one or more lordosis support regions, and one or more pelvic support regions. The various support regions can have different compression hardness, firmness, and / or elasticity. As a result, the user can sink into or be supported by the outer surface to different depths in each support region. The various support regions can also take into account the user's weight distribution across at least a portion of the first and / or second outer surfaces. For example, different compression hardnesses of the support regions can be used to account for the fact that the user's head weighs less than the pelvis. Different compression hardnesses in the various support regions can also ensure that the user's spine or back is straight, such as when the user is in a lateral position, or has a typical S-shape, such as when the user is in a supine position.

[0126] Different compression firmness in each support region can be achieved by using different materials, e.g., mattress foam and / or polyurethane foam of different firmness or softness, by different profiles, and / or by different structures of the first and / or second outer surfaces. Such profiles can comprise, for example, grooves, corrugations, notches, cutouts, notches, transverse grooves, depressions, channels, indents, and / or cutouts.

[0127] According to one embodiment, the mattress (or mattress element) comprises a first half and a second half, which are arranged in front of and behind the longitudinal axis of the mattress. In each half, the mattress (or one or more mattress elements) comprises a head support region, a neck support region, a shoulder support region, a lordosis support region, and a pelvic support region. Thus, the head support region, neck support region, shoulder support region, lordosis support region, and pelvic support region of two of the mattresses (or one or more mattress elements) can be arranged in mirror symmetry with respect to the central lateral axis and / or the central lateral plane.

[0128] According to one embodiment, the first and second halves of the mattress (or one or more mattress elements) are configured symmetrically, in particular with mirror symmetry, relative to the central transverse axis and / or central transverse plane of the mattress or reclining furniture. The mattress (or individual mattress elements) can be configured with mirror symmetry, in particular with regard to the configuration of the various support areas and the structure and / or contours of the various support areas.

[0129] For example, support regions can be configured in each of the first and second halves of the mattress (or one or more mattress elements) as follows: Each head support region extends from each end of the mattress in the direction of the central lateral axis; Each neck support region connects to each of the head support regions and extends further in the direction of the central lateral axis; Each shoulder support region connects to each of the neck support regions and extends further in the direction of the central lateral axis; Each lordosis support region connects to each of the shoulder support regions and extends in the direction of the central lateral axis; and Each pelvic support region connects to each of the lordosis support regions and extends to the central lateral axis.

[0130] According to one embodiment, the first and / or second side of the mattress comprises, at least in partial regions, at least one recess and / or at least one transverse groove. In this case, each support region can comprise one or more transverse grooves. The transverse grooves in different regions can differ, for example, in number, geometric shape, cross-section, size, depth, etc.

[0131] The lateral grooves may extend substantially parallel to the lateral axis of the reclining furniture across the entire width of the first and / or second sides of the mattress. Each lateral groove may be perceived as a macroscopic depression, indentation, or recess.

[0132] According to one embodiment, the mattress comprises at least two mattress elements at least partially stacked on top of one another. Alternatively or additionally, the mattress comprises at least one first mattress element and one second mattress element at least partially stacked on top of one another. The mattress may also comprise three or more mattress elements. In this case, the thicknesses of the mattress elements, measured perpendicular to the longitudinal and transverse axes, may be the same or different from one another.

[0133] According to one embodiment, each of the two mattress elements comprises an outer surface and a contact surface. The contact surface of the first mattress element is at least partially in contact with the contact surface of the second mattress element. At least one of the outer surfaces and / or the contact surface of at least one of the first and second mattress elements comprises a profile, in particular a profile with one or more transverse grooves. For example, a profile can be provided on one or both outer sides. Optionally, a profile with one or more transverse grooves can be additionally or exclusively configured on one or both contact surfaces.

[0134] In particular, one of the outer surface and the contact surface of each mattress element can be provided with a profile. The profiles can be different from each other. If both contact surfaces are provided with a profile, the profiles of the two mattress elements can optionally at least partially interlock with each other and / or can be configured to correspond to each other.

[0135] According to one embodiment, the outer surface and / or contact surface of the first mattress element comprises a first profile. The outer surface and / or contact surface of the second mattress element comprises a second profile. The first profile differs from the second profile at least in part so that the hardness of the first mattress element differs from the hardness of the second mattress element. The profiles can, for example, comprise different transverse grooves.

[0136] The hardness or compression hardness of the first and second mattress elements can further be influenced, for example, by the choice of material for each mattress element. For example, various foams (such as polyurethane foam) can be selected. Furthermore, the hardness can be influenced by suitable structures, such as grooves, transverse grooves, corrugations, notches, cutouts, recesses, channels, indentations, and / or cutouts, which can be configured in the first and / or second outer surfaces and / or the first and / or second contact surfaces. Furthermore, the connection of the first mattress element to the second mattress element is particularly achieved by the choice and / or configuration of a profile that influences at least one of the contact surfaces. Alternatively or additionally, the hardness in various regions of the mattress elements can differ, for example, by the choice of material, the contour and / or structure of each outer surface, and / or the design of the contact surfaces. For example, the shoulder support region can be designed to be slightly softer than the neck support region so that the user's shoulders sink deeper into the outer surface of the mattress than the user's neck, particularly when the user is lying on the outer surface of each mattress element.

[0137] According to one embodiment, at least one of the first and second contact surfaces is provided, at least in partial areas, with a profile having one or more lateral grooves, which can further improve the support properties or influence the support properties.

[0138] According to one embodiment, the profile is arranged only on the second contact surface of the second mattress element, alternatively or additionally, no profile is arranged on the first contact surface of the first mattress element.

[0139] According to one embodiment, the first and second contact surfaces comprise corresponding and / or at least partially interlocking profiles, for example, the profiles may interlock in a toothed manner to secure the mattress elements together.

[0140] According to one embodiment, the hardness of the first mattress element is greater than the hardness of the second mattress element, or vice versa.

[0141] According to one embodiment, at least one, in particular a plurality of, transverse grooves extending in the transverse direction of the mattress are configured in the first outer surface of the first mattress element and / or in the second outer surface of the second mattress element between at least one head support region and at least one neck support region. The transverse grooves have a T-shaped, trapezoidal, and / or triangular cross section. The transverse grooves can be configured, for example, as grooves, corrugations, notches, cutouts, depressions, channels, indentations, and / or cutouts across the entire transverse width of the mattress (also known as a combination mattress).

[0142] Typically, at least one lateral groove can be formed in at least one of the head support region, neck support region, shoulder support region, lordosis support region, and pelvic support region. Generally, the profile of each support region can be provided and / or defined by a lateral groove or the absence of a lateral groove. The lateral grooves of the various support regions can differ from one another in terms of their geometric shape, their cross-section, and the depth, dimensions, length, and / or width of each lateral groove. This allows the hardness of each support region to be varied and / or matched to one another. In this case, one or more lateral grooves can have a teardrop-shaped, circular, triangular, trapezoidal, round, oval, elliptical, or T-shaped cross-section. Typically, the depth of the lateral groove measured along the vertical axis can be approximately 1 to 5 cm, and the width of the lateral groove measured along the longitudinal axis can be approximately 1 to 4 cm.

[0143] Optionally, one or more lateral grooves may also be introduced into the mattress material such that the outside of the lateral grooves are at least partially covered by the mattress material.

[0144] According to one embodiment, at least one, in particular a plurality of, transverse grooves extending in the transverse direction of the mattress are configured in the first outer surface of the first mattress element and / or in the second outer surface of the second mattress element in at least one pelvic support region, the transverse grooves having a T-shaped, trapezoidal and / or triangular cross section.

[0145] According to one embodiment, at least one, in particular a plurality of, transverse grooves extending in the transverse direction of the mattress are configured in the first outer surface of the first mattress element and / or in the second outer surface of the second mattress element in at least one shoulder support region, the transverse grooves having a round, oval, teardrop-shaped and / or elliptical cross section.

[0146] According to one embodiment, a plurality of lateral grooves extending in the transverse direction of the mattress are configured in at least one shoulder support region on the first outer surface of the first mattress element, each having a round and / or teardrop-shaped cross section. The lateral grooves configured in the shoulder support region have the same diameter, cross section, and / or size. In this case, the size of the lateral groove may refer to a dimension measured in the longitudinal direction of the mattress, such as the width of each lateral groove.

[0147] According to one embodiment, a plurality of lateral grooves extending in the transverse direction of the mattress are arranged in at least one shoulder support region on the second outer surface of the second mattress element, each having a round and / or teardrop-shaped cross section. At least some of the lateral grooves arranged in the shoulder support region have different diameters and / or sizes. In this case, the diameters, dimensions, widths and / or sizes of the lateral grooves can decrease in the direction of the central lateral axis and / or the central plane.

[0148] A further aspect of the present disclosure relates to the use of reclining furniture as described above and below for lying down and / or sitting outdoors, in the open, and / or in harsh environments.

[0149] A further aspect of the present disclosure relates to the use of a base element, as described above and below, to deform and / or adjust a mattress placed thereon, in other words, the base element can be used in combination with any mattress that can be placed on the base element, in particular on its cover layer.

[0150] Further features, advantages and applicability of the invention will become apparent from the following description of exemplary embodiments and drawings.

[0153] Figure 1a shows an exploded view of a base element 100 according to one embodiment. Figure 1b shows an adjustment device 300 for the base element of Figure 1a. Figure 2 shows a top view of the base element 100 of Figure 1a.

[0154] The base element 100 comprises a frame element 101a and a cover layer 101b. The base element 100 also comprises an adjustment device 300. The frame element 101a has a compartment 102. The compartment 102 is configured and / or dimensioned such that the adjustment device 300 can be accommodated and / or integrated within the compartment 102. Thus, the adjustment device 300 is at least partially accommodated within the compartment 102.

[0155] A cover layer 101b of the base element is disposed on the frame member 101a. The frame element 101a may be constructed partially or entirely from foam. Similarly, the cover layer 101b may be constructed partially or entirely from foam. However, other materials are also contemplated.

[0156] The cover layer 101b may optionally include a cutout 114. The cutout 114 may be configured to provide space for assembly / disassembly of one or more components of the adjustment device 300.

[0157] The adjustment device 300, configured to deform or adjust the base element 100 and / or the mattress 202 placed thereon, comprises one or more drives 108, 108', for example two electric motors, and at least two rails 104, 104', which are arranged substantially parallel to one another and connected to one another via at least one cross member 103, where each of the rails 104, 104' extends substantially parallel to the longitudinal axis 107 of the base element 100. The at least one cross member 103 extends substantially parallel to the transverse axis 109 of the base element 100.

[0158] Each of the rails 104, 104' comprises, for example, three rail elements 105a, 105b, 105c, which are arranged in the longitudinal direction of each rail 104, 104' and / or parallel to the longitudinal direction 107. In this case, the rail elements 105a, 105b, as well as 105b and 105c, are in each case movably connected to one another at their ends via joints 106. As a result, the rail elements 105a, 105b, as well as 105b and 105c can pivot via the joints 106 about axes parallel to the transverse axis 109.

[0159] In the example of Figures 1a, 1b and 2, the base element 100 or adjustment device comprises two drives 108, 108' and two drive mechanisms 115, 115'. Each drive mechanism may comprise one or more cable tensioning mechanisms and / or gear mechanisms, which may be at least partially arranged and / or integrated in one or more rail elements 105a-105c. Furthermore, the adjustment device comprises two cross members 103, 103', which may each be assigned to a drive mechanism 115, 115'.

[0160] A shaft 135 can be arranged in each of the cross members 103, 103' and connected to one of the drives 108, 108'. Alternatively, the cross members 103, 103' can in each case constitute the shaft 135.

[0161] In this case, the drives 108, 108' are arranged in one of the two rails 104' and can operate drive mechanisms, such as cable tensioning mechanisms and / or gear mechanisms, present in the rail elements of this rail. The rotation of each drive 108, 108' is transmitted via the associated shaft 135 or cross member 103, 103' to the oppositely arranged rail 104 and drive mechanisms, such as cable tensioning mechanisms and / or gear mechanisms, present in the rail elements of this rail, and can operate them. In this way, the regions 117a, 117b, 117c arranged between the pair of opposing rail elements 105a-105c in the transverse direction 109 can be displaced, pivoted, and / or tilted relative to one another.

[0162] To extend the rails 104, 104' in the longitudinal direction 107, longitudinal support struts 302 are arranged at each end of each rail element 105a, 105c, such as at each head and / or foot end of each rail 104, 104' of the base element 100. These are spaced apart from one another in the lateral direction 109 and interconnected via one or more lateral support struts 110. Thus, on the one hand, regions 117a and 117c can be enlarged, increasing the stability of the adjustment device 300 and allowing it to withstand increased loads. In addition to regions 117a-117c, regions protruding beyond the front, head, and / or foot ends of the adjustment device 300 can also be individually displaced. Thus, in the example of FIGS. 1a, 1b, and 2, at least three, four, or five different, individually configurable regions can be created. More or fewer regions can also be provided.

[0163] The adjustment device 300 further comprises a control unit 310. The control unit 310 is configured to control the adjustment device 300 and / or one or more of the drives 108, 108'. For example, the control unit 310 can adjust the direction and speed of rotation, etc. This can be done via appropriate control signals.

[0164] The control unit 310 further comprises an interface 112 coupled to an operating device 122 via a cable connection. The operating device 122 may comprise a user interface such as a display, buttons, etc. for controlling the control unit and / or the adjusting device 300. Alternatively or additionally, the adjusting device 300 comprises a wireless interface 312 for communicating with the receiver 120, which may be a smartphone, tablet, PC, notebook, server, etc., as shown in Figure 2.

[0165] Furthermore, the base element 100 has an energy storage device 315, such as a battery or accumulator, for supplying electrical energy to the adjusting device 300. The energy storage device 315 can be charged, for example, via a cable. This cable can optionally be led through the frame element 101a and / or the cover layer 101b. Inductive charging or other techniques are also conceivable.

[0166] Additionally, the components of conditioning device 300 can be configured to be at least partially waterproof.

[0167] Figure 3 shows a base element 100 according to one embodiment. Unless otherwise stated, the base element 100 of Figure 3 comprises the same elements and features as the base element 100 of Figures 1a-2.

[0168] The base element 100 of Fig. 3 further comprises a base cover 301. The frame element 101a, the cover layer 101b and / or the adjustment device 300 are at least partially, in particular completely, housed within the base cover 301. The base cover 301 is configured in particular to prevent the mattress 202 placed on the base element 100 from slipping. In this case, the base cover 301 can be made from any material and / or fabric, in particular natural fibers, synthetic fibers or a mixture thereof. The base cover 301 can also serve to protect the base element 100.

[0169] Optionally, the base cover may be at least partially waterproof, e.g., on the underside, sides, and / or top side. In particular, the base cover 301 may be at least partially rubberized, coated, and / or latexed, e.g., on its outer, inner, upper, and / or lower side.

[0170] The base cover 301 may be at least partially composed of a rubber-like material. Alternatively or additionally, the base cover 301 is at least partially rubberized. Alternatively or additionally, the base cover 301 is at least partially composed of latex. In particular, the top surface on which the mattress 202 can be placed and / or the outside of the base cover 301 may be at least partially rubberized, coated, and / or provided with latex to prevent the mattress 202 from slipping.

[0171] The base cover 301 comprises an at least partly circumferential fastener 303, in particular a slide fastener 303, which can be opened and closed to insert and / or remove the base element 100. Optionally, the (slide) fastener 303 can be at least partly waterproof.

[0172] The base cover 301 may further comprise one or more cable bushings 350 for passing cables of the control unit 112 and / or the operating device 120, etc. Optionally, the cable bushings 350 may be mechanically reinforced, for example with eyelets. Further optionally, the cable bushings 350 may be configured with a sealing design, at least partially sealingly enclose the cables, and / or comprise sealing elements.

[0173] 4 and 5 each show a reclining piece of furniture 200 according to one embodiment.

[0174] The reclining furniture 200 comprises a base element 100. A mattress 202 is positioned and / or rests on the base element 100 at a first side 203. Opposite the first side 203, the mattress 202 defines a lying surface 205 for a user, where the lying surface is opposite the bottom surface 101 of the base element 100. The base element 100 of Figures 4 and 5 can be configured like the base elements 100 described in the previous figures.

[0175] The reclining furniture 200 further comprises at least one reclining furniture cover 204. The reclining furniture cover 204 at least partially, in particular completely, encloses the base element 100 and the mattress 202. In this case, the reclining furniture cover 204 may be configured as a mattress cover 204, as described with reference to Figures 6 to 8. Optionally, the reclining furniture cover 204 and / or the mattress cover 294 may be at least partially coated, rubberized, and / or latexed to prevent water ingress.

[0176] As an alternative or in addition to the mattress cover 204, a further reclining furniture cover 204 may be provided in the form of an at least partially waterproof outer cover 204, which may at least partially, in particular completely, enclose the base element, the mattress and optionally the mattress cover.

[0177] Optionally, a further outer cover may be provided that at least partially, and in particular completely, surrounds the outer cover 204. The further outer cover may be configured similarly to a mattress cover, as described above and below. Optionally, the further outer cover may also be at least partially coated, rubberized, and / or latexed to prevent water ingress.

[0178] One or more of the reclining furniture covers 204 may be at least partially, in particular completely, provided with a circumferential fastener 206, such as a slide fastener, which may optionally be at least partially waterproof.

[0179] Additionally, for transport purposes, two or more carrying handles 210, 210' may be provided on each side of the reclining furniture 200. These may be at least 2-10 cm wide or wider and / or at least 5-20 cm long or longer to ensure high stability and comfort during transport.

[0180] In Fig. 4, the reclining furniture 200 is shown in a horizontal position. In contrast, in Fig. 5, the individual zones 117a-117c have been adjusted and / or displaced by the adjustment device 300. As a result, a total of at least four mutually differently arranged and / or positioned reclining zones 401, 402, 403, 404 are generated on the reclining furniture 200 or reclining surface 205. A user can individually change, set, and / or adapt the individual zones or reclining zones via one of the operating devices 120, 122.

[0181] Figure 6 shows a perspective view of the mattress cover 204 of the reclining furniture 200 according to one embodiment. Figure 7 shows a highly simplified partial top view showing the exterior of the mattress cover 204 of Figure 6. Figure 8 shows a regional schematic cross-section through the cover fabric of the mattress cover 204 of Figures 6 and 7.

[0182] 6, a mattress cover 204 or mattress protector cover 204 is illustratively shown stretched over a mattress 202 and base element 100. The cover 204 forms a first lying surface on an upper side 205 and optionally a second lying surface for a user on an opposing lower side 101.

[0183] The mattress cover 204 is formed in the circumferential direction from the same cover fabric 5. The lateral transverse faces 6 and longitudinal faces 7 also merge, optionally seamlessly, into the upper side 6 and lower side 7. However, in other embodiments, the separation of the surfaces of the cover fabric 5 can alternatively be provided by seams and, if necessary, by welt tape (Kederband).

[0184] Circumferential fasteners 206 in the form of slide fasteners are sewn to the mattress cover 204 (or mattress protective cover 204) on the lateral faces 6 and longitudinal sides 7 for inserting and removing the mattress 202 and / or base element 100. In addition, a number of handles 210 are provided on the lateral longitudinal faces 7 for lifting the base element 100 and / or mattress 2020 covered by the mattress cover 202 (or mattress protective cover 2), of which only one handle 210 is shown by way of example.

[0185] As can be seen in part X of Figure 6, which shows the entire surface of the mattress cover 204 (or mattress protective cover 204), and as can be seen in Figures 7 and 8, the cover fabric 5 is made up of a weft-knitted spacer knit fabric 10, such as a three-dimensional weft-knitted spacer knit fabric, up to its outer side 11.

[0186] The cover fabric 5 has a honeycomb-like mesh structure with outwardly opening recesses 12 arranged in a regular, fine configuration. In this case, the recesses 12 preferably have an outwardly facing round, rounded, elliptical, and / or oval cross section. This cross section can have dimensions, in an untensioned state, of, for example, 2 mm to 4 mm in width and, for example, about 3 mm to 5 mm in length.

[0187] The material webs 13 made of the weft-knitted spacer knit fabric 10, which are present between the regularly offset recesses 12, can have widths of at least approximately the same dimension.

[0188] The cover fabric 5 of the cover 1 exists as a two- or three-layer weft-knitted spacer knit fabric having a top layer 14 forming the outer side 11, an optional middle layer 15 knitted with the top layer 14 and together forming the weft-knitted spacer knit fabric 10, and an inner or bottom layer 16 knitted with the top layer 14 and / or the optional middle layer 15.

[0189] The top layer 14 can comprise monofilament yarns, such as smooth monofilament yarns, or multifilament yarns, such as textured twisted multifilament yarns. Similarly, the bottom layer 16 can comprise monofilament yarns, such as smooth monofilament yarns, or multifilament yarns, such as textured twisted multifilament yarns. Similarly, the middle layer 15 can be at least partially composed of monofilament or multifilament yarns.

[0190] One or more of the top layer 14, middle layer 15, and bottom layer 16 can further include and / or be at least partially composed of natural fibers, as described above. The natural fibers can be animal hair fibers, wool fibers, cotton fibers, hemp fibers, eucalyptus fibers, bamboo fibers, flax fibers, wood fibers, viscose fibers, flax fibers, silk fibers, plant fibers, or combinations thereof. Compared to synthetic fibers, such natural fibers can be characterized by improved sustainability, odor neutrality, skin compatibility, durability, and / or robustness.

[0191] The top layer 14 further comprises a fine knit structure 17 on the outer side 11, which provides a soft feel to the surface.

[0192] In terms of thickness, the upper layer 14 in the advantageous embodiment shown is dimensioned to occupy at least 70% to 80% of the total thickness of the cover fabric 5 in order to take full advantage of the microclimate advantages of the weft-knitted spacer knit fabric 10.

[0193] To allow for maximum air circulation and optimal moisture transport to the exterior 11, the honeycomb recesses 12 extend substantially through the thickness of the top layer 14 and middle layer 15, until adjacent to the bottom layer 16. As a result, the cover fabric simultaneously has high flexibility and widthwise extensibility due to the recesses 12. The heightwise elasticity causes softness that can be defined by the filler in the middle layer 14 depending on the degree of softness desired.

[0194] Of course, the cover fabric 5 can be manufactured using all known spacer knitting methods, depending on the application, and all known finishing methods, such as using washing, bleaching, and shrinking processes following the knitting process. Optionally, the mattress cover 204 can be at least partially coated, rubberized, and / or latexed to prevent water ingress.

[0195] FIGS. 9a-9f each illustrate a portion of a mattress 202 of a reclining furniture piece 200 according to several embodiments. FIG. 9a illustrates a top view of the first mattress element 2 of the mattress 202 of the reclining furniture piece 200. The mattress 202 of FIGS. 9a-9f can be combined with all of the above aspects of the reclining furniture piece 200, or individual aspects can be interchanged. FIG. 9b schematically illustrates a cross-section of the first mattress element 2 of FIG. 9a. The first mattress element 2 is shown without transverse grooves in FIGS. 9a and 9b. FIG. 9c illustrates a side view of the first mattress element 2 of FIGS. 9a and 9b having multiple transverse grooves. FIG. 9d illustrates a top view of a second mattress element 3 according to one embodiment of the present invention. FIG. 9e illustrates a cross-section of the second mattress element 3 of FIG. 9d without transverse grooves. FIG. 9f illustrates a mattress 202 or combination mattress 202 of the reclining furniture piece 200 according to one embodiment of the present invention. In this case, the mattress 202 of Figure 9f comprises a first mattress element 2 as described with reference to Figures 9a to 9c and a second mattress element 3 as described with reference to Figures 9d and 9e.

[0196] The first mattress element 2 comprises a first outer surface 21 and an oppositely arranged first contact surface 32. In this case, the first outer surface 21 is configured as a first lying surface 21 for the user. The second mattress element 3 comprises a second outer surface 31 and an oppositely arranged second contact surface 32. In this case, the second outer surface 31 is optionally configured as a second lying surface 31 for the user. The first and second mattress elements 2, 3 are stacked on top of each other such that the first and second contact surfaces 22, 32 at least partially touch and make contact with each other.

[0197] The two mattress elements 2, 3 and / or the mattress 202 and / or the reclining furniture 200 each include a plurality of support areas 41, 42, 43, 44, 45 for ergonomically and comfortably accommodating a user. In this case, the support areas 41, 42, 43, 44, 45 may include a head support area 41, a neck support area 42, a shoulder support area 43, a lordosis support area 44, and a pelvis support area 45.

[0198] The mattress 202 has a longitudinal direction x (107 in FIGS. 1a-3) or longitudinal axis x running parallel to the longitudinal sides of the mattress 202, a lateral direction z (109 in FIGS. 1a-3) or lateral axis z running parallel to the lateral sides of the mattress z, and a vertical axis y running transversely and / or perpendicularly to the longitudinal direction x and the lateral direction z. The length of the mattress 202 of the reclining furniture 200 is measured in the longitudinal direction. The width of the mattress 202 is measured in the lateral direction z. The thickness or height of the mattress is measured along the vertical axis y. In this case, the length of the mattress 202 can be equal to or greater than the width of the mattress 202. The first mattress element 2 and the second mattress element 3 can have the same or different heights and / or thicknesses. In this case, the x direction can run parallel to the longitudinal axis 107 of the base element 100 and / or the reclining furniture 200. Alternatively or additionally, the z-direction may run parallel to the lateral axis 109 of the base element 100 and / or the reclining furniture piece 200 .

[0199] Furthermore, the mattress 202 of the reclining furniture 200 comprises a central transverse axis 5 and / or central transverse surface 5 running parallel to the transverse direction z and located centrally between two opposite ends of the mattress 202 in the longitudinal direction x. In this case, the central transverse axis 5 and / or central transverse surface 5 separates the first mattress element 2 into a first half 2a and a second half 2b. Similarly, the central transverse surface 5 and / or central transverse axis 5 separates the second mattress element 3 into a first half 3a and a second half 3b.

[0200] In this case, each of the halves 2a, 2b, 3a, 3b of the first and second mattress elements 2, 3 comprises support areas 41, 42, 43, 44, 45. In this case, the support areas 41, 42, 43, 44, 45 are arranged mirror-symmetrically with respect to the central transverse axis 5. In this case, the individual support areas 41, 42, 43, 44, 45 can at least partially differ from one another in terms of hardness, firmness, compression hardness and / or resilience. For example, the support areas 41, 42, 43, 44, 45 can have at least partially different profiles, contours and / or structures from one another, such as in the form of transverse grooves 51, 52, 53, 54 arranged in each support area 41, 42, 43, 44, 45. In this case, the lateral grooves 51, 52, 53, 54 can be configured in the first and / or second outer surface 21, 31 and can extend across the entire width of the mattress 200 in the lateral direction z. In order to adapt the firmness of the individual support areas 41, 42, 43, 44, 45, the profile and / or the lateral grooves 51, 52, 53, 54 in each support area 41, 42, 43, 44, 45 can differ from one another in their cross-section, their geometry, their shape, their number, their depth measured along the vertical axis y and / or their thickness or size measured along the longitudinal axis x.

[0201] As can be seen in Figure 9c, the first mattress element 2 comprises a respective first transverse groove 51 in each of the two halves 2a, 2b, which separates the head support region 41 from the neck support region 42. In this case, the first transverse groove 51 has a T-shaped cross section.

[0202] Furthermore, the first mattress element 2 includes five second transverse grooves 52 in each of the two halves 2a, 2b of the shoulder support region 43, each having a round, oval, elliptical, and / or teardrop-shaped cross section. In this case, the geometry, width, dimensions, size, thickness, and / or diameter of the five second transverse grooves 52 in the shoulder support region 43 of the two halves 2a, 2b of the first mattress element 2 are identical. The neck support region 42 of the first mattress element 2 is separated from each of the shoulder support regions 43 adjacent to the neck support region 42 by one of the second transverse grooves 52. Similarly, the lordosis support region 44 adjacent to the shoulder support region 43 in the direction of the central transverse axis 5 is separated from each of the shoulder support regions 43 by one of the second transverse grooves 52. Furthermore, each lordosis support region 44 is separated from the adjacent pelvic support region 45 by a third lateral groove 53. A total of three third lateral grooves 53 are configured in the two pelvic support regions 45 adjacent to each other at the central lateral axis 5, each having a T-shaped and / or triangular cross-section. In this case, the three third lateral grooves 53 have the same geometry, width, dimension, size, thickness, and / or diameter. The central third lateral groove 53 of the three third lateral grooves 53 can be located in the central lateral surface 5 and can define the boundary between the first half 2a and the second half 2b.

[0203] As shown in Figure 9f, at least one additional lateral groove 54 can be configured in each of the lordosis support regions 44. The additional lateral grooves 54 can, for example, have round and / or oval cross-sections.

[0204] As can be seen in Figure 9f, the first mattress element 2 has no profile, contour and / or structure on its first contact surface 22. In other words, the first contact surface 22 is formed completely flat. However, optionally, the first contact surface 22 can also be configured with a profile, at least in partial areas. Any cross-sectional profile for the transverse grooves is contemplated here, as described above and below, such as round, oval, elliptical, triangular, square, polygonal, trapezoidal, etc.

[0205] As can be seen in Figure 9f, the second mattress element 3 comprises an individual first transverse groove 61 in each of its two halves 3a, 3b, which separates the head support region 41 from the neck support region 42. In this case, the first transverse grooves 61 are formed similarly to the first transverse grooves 51 of the first mattress element 2 and have a T-shaped cross-section. Furthermore, the second mattress element 3 comprises a total of five second transverse grooves 62 in each of its two halves 3a, 3b in the shoulder support region 43, each of which has a round, oval, elliptical, and / or teardrop-shaped cross-section. In this case, the second transverse grooves 62 of the second mattress element 3 are formed similarly to the second transverse grooves 52 of the first mattress element. However, the widths, dimensions, sizes, thicknesses, and / or diameters of the five second transverse grooves 62 in the shoulder support region 43 of the two halves 3a, 3b of the second mattress element 3 decrease continuously in the direction of the central transverse axis 5. The neck support region 42 of the second mattress element 3 is separated from each of the shoulder support regions 43 adjacent to the neck support region 42 by one of the second transverse grooves 62. Similarly, the lordosis support regions 44 adjacent to the shoulder support regions 43 in the direction of the central transverse axis 5 are separated from each of the shoulder support regions 43 by one of the second transverse grooves 62. Furthermore, each of the lordosis support regions 44 is separated from the adjacent pelvic support region 45 by a third transverse groove 63. A total of three third transverse grooves 63 are formed in the two pelvic support regions 45 adjacent to each other along the central transverse axis 5. These are formed similarly to the transverse grooves 53 of the first mattress element 2 and each have a T-shaped and / or triangular cross section. In this case, the three third transverse grooves 63 have the same geometry, width, dimension, size, thickness, and / or diameter. The central third transverse groove 63 of the three third transverse grooves 63 may run in the central transverse surface 5 and may define the boundary between the first half 3a and the second half 3b. Furthermore, similar to the further transverse grooves 54 of the first mattress element, at least one further transverse groove 64 may be configured in each of the lordosis-supporting regions 44 of the second mattress element 3. The further transverse grooves 64 may, for example, have a round and / or oval cross-section.

[0206] The transverse grooves 61, 62, 63, 64 of the second mattress element 3 are arranged opposite the transverse grooves 51, 52, 53, 54 of the first mattress element 2 and are arranged on the second outer surface 32 of the second mattress element 3. Furthermore, the two halves 2a, 2b of the first mattress element 2 and the two halves 3a, 3b of the second mattress element 3 are formed in perfect mirror symmetry with respect to the central transverse axis 5 or central transverse plane 5.

[0207] As shown in Figure 9f, the second mattress element 3 is provided on its second contact surface 32 with a profile 33 having a plurality of transverse grooves 34. The transverse grooves 34 are illustrated with a rectangular cross section, although any other cross section is conceivable.

[0208] The profile 33 may also be wavy, with multiple peaks and valleys. Alternatively or additionally, the profile 33 or other profiles may be introduced into the contact surface 22 of the first mattress element 2. Profiles and / or transverse grooves may also be introduced into both contact surfaces, which may at least partially interlock with each other.

[0209] Exemplary lateral grooves for the first outer surface, the second outer surface, the first contact surface, and / or the second contact surface are shown in subsequent figures.

[0210] 10-13 each show exemplary lateral grooves in a mattress 202 of a reclining piece of furniture according to one embodiment. Specifically, a longitudinal cross section through each mattress 202 is shown.

[0211] The mattress 202 of Figure 10 consists of a total of three parts and comprises three mattress elements 2, 3, 3'. In contrast, the mattress 202 of Figures 11 to 13 comprises only two mattress elements 2, 3. However, any number of more or fewer mattress elements may be provided.

[0212] The transverse grooves and / or profiles shown in Figures 10 to 13 are merely schematically and exemplarily arranged on the contact or outer surfaces shown there of the mattress elements 2, 3, 3'. However, the transverse grooves and / or profiles can also be arranged on any other surface of the mattress 202.

[0213] In the example of Figure 10, the first mattress element 2 does not have a profile or transverse grooves. The second mattress element 3 has trapezoidal transverse grooves 500 on its contact surface 33 and rectangular transverse grooves 600 on the side or surface opposite this contact surface 33, which are recessed, spaced from this surface and embedded and / or integrated into the second mattress element 3. A further mattress element 3' without a profile forms a further outer surface of the mattress 202.

[0214] In the example of Figure 11, the first mattress element 2 comprises transverse grooves 500 with a round cross section on the outer side 21 and transverse grooves 550 with a rectangular, trapezoidal or triangular cross section on the contact surface 22. The second mattress element 3 has transverse grooves 600 with a round cross section only on the outer side 31. The contact surface 32 is unprofiled.

[0215] In Figure 12, the first mattress element 2 comprises a bean-shaped transverse groove 500. The transverse groove 500 is introduced into the first mattress element from the first contact surface 21 via a cut 501. As a result, the transverse groove 500 is located closer to the first outer side 21 of the first mattress element 2 than to the first contact surface 22 of the first mattress element 2. A similar transverse groove 600 with a cut 601 is introduced into the second mattress element 3 via the second contact surface 32. In this case, the transverse groove 600 is formed in a boomerang shape, a coat hanger shape, and / or a triangular shape. Furthermore, a further transverse groove 603 with a round cross section is introduced into the second mattress element 3. The second outer side 31 of the second mattress element 3 is free of profiles.

[0216] In the example shown in Figure 13, the first mattress element 2 and the second mattress element 3 are provided with corresponding profiles and / or transverse grooves 500, 600 on their contact surfaces 22, 32, which at least partially interlock with each other like teeth. The outer surfaces 21, 31 of the two mattress elements 2, 3 are free of profiles.

[0217] Additionally, it should be noted that "comprises" and "comprises" do not exclude other elements, and "a" or "an" do not exclude a plurality. Furthermore, it should be noted that features described with reference to one of the above embodiments can be used in combination with other features of the other above embodiments. Reference signs in the claims are not to be considered as limitations.
