Description

[0001] Adjustable base element for reclining furniture and reclining furniture

[0002] Reference to related applications

[0003] This application claims priority from German utility model application No. 20 2023 106 607.0, filed on November 10, 2023, which is incorporated in its entirety by reference into this document.

[0004] Technical area

[0005] The invention generally relates to the field of reclining furniture and / or sleeping furniture. In particular, the invention relates to a base element for a reclining furniture that is at least partially deformable and / or adjustable, as well as to a reclining furniture comprising such a base element and a mattress.

[0006] Background of the invention

[0007] Reclining furniture has been used as a base and / or lying surface for a user for some time and is constantly being developed further, particularly with regard to user comfort and ergonomics. Reclining furniture is usually adapted to specific requirements.

[0008] For example, there are outdoor lounge furniture items, such as garden furniture or similar items, which typically provide a foam base or cushion for the user to lie on. Such bases are often uncomfortable and do not adequately meet the requirements for comfort and ergonomics. Furthermore, such lounge furniture items are generally only partially adjustable, giving users few options for changing their reclining position. Furthermore, lounge furniture in various forms is used indoors as sleeping furniture, armchairs, couches, or similar items. Such lounge furniture items typically feature a cushion or mattress.To improve sleeping comfort, mattresses can, for example, be designed with adjacent zones, areas and / or support areas of different hardness, compressibility, compressibility and / or elasticity in the lengthwise direction of the mattress, for example to adapt the penetration depth of the user lying on the mattress to their body shape. This can ensure that the user lies on the mattress with a spine that is as straight as possible when lying on their side. The same applies when lying on their back, where the spine should be supported so that it has a natural S-shape. By providing several support areas of different hardness and / or different degrees of hardness, the user's weight distribution can also be advantageously taken into account and thus an ergonomic posture of the user can be ensured, for example in several sleeping positions or sleeping postures of the user.

[0009] Common lounge furniture is therefore generally designed, constructed, and suitable only for specific applications, such as indoor or outdoor use. Furthermore, common lounge furniture often fails to meet the requirements in terms of comfort, ergonomic seating, and / or adaptability to individual needs.

[0010] Summary of the invention

[0011] Embodiments of the invention can advantageously provide an improved base element for a reclining furniture and an improved reclining furniture.

[0012] This is made possible in particular by the subject matter of the independent claims. Advantageous embodiments and further developments are specified in the dependent claims and the following description.

[0013] One aspect of the present disclosure relates to a base element configured to deform and / or adjust a piece of reclining furniture and / or a mattress placed or arranged on the base element, at least in regions and / or sections. For example, the base element can be configured to support and / or deform a mattress, at least in regions. The base element comprises a frame element formed at least partially from elastically deformable material, in particular at least partially from foam, viscose foam, polyurethane foam, or the like, which frame element has a base surface on a first side, for example a first longitudinal side, and a second side opposite the first side. The frame element has a compartment on the second side. The base element further comprises an at least partially elastically deformable cover layer.This can be made from the same material as the frame element, for example at least partially also from foam and the other materials mentioned. The cover layer is arranged on the second side of the frame element, so that the cover layer is at least partially arranged in the compartment. Optionally, the compartment is at least partially delimited, defined, covered and / or closed by the cover layer. The cover layer and the frame element together form a receiving space arranged in the compartment. In addition, the cover layer forms a support surface of the base element, arranged opposite the first side or floor surface, for supporting a mattress. The base element also has an adjustment device which is at least partially arranged and / or received in the receiving space between the cover layer and the frame element.The adjustment device has at least one drive and a drive mechanism coupled to the drive, in particular mechanically and / or electrically coupled, and is configured to deform, displace, and / or adjust the base element and / or a mattress placed on the base element, at least in certain regions and / or sections. The drive mechanism has at least two rails, which are arranged substantially parallel to a longitudinal axis of the base element and which are spaced apart from one another and / or coupled to one another parallel to a transverse axis of the base element by at least one cross strut, which extends parallel to the transverse axis and / or transversely to the longitudinal axis of the base element.Each of the at least two rails has at least two rail elements which are arranged one behind the other parallel to the longitudinal axis or longitudinal direction of the base element and are coupled to one another via at least one joint and / or an articulated connection, so that the at least two rail elements of each rail can be displaced, pivoted and / or tilted relative to one another via the at least one drive.

[0014] By shifting and / or pivoting the rail elements of the rails, the reclining furniture, the mattress and / or the base element can be deformed, shaped and / or moved, in particular in such a way that a lying position for a user can be adjusted variably and / or changeably.

[0015] The adjustment device can be protected within the frame element or the receiving space, allowing adjustment or deformation of the base element. This can enable adjustment of one or more sections and / or areas (or lying areas) of a mattress placed on the base element and / or of the reclining furniture as needed, as explained in detail below.

[0016] In the context of the present disclosure, the reclining furniture may refer to any type of reclining furniture, such as a sleeping furniture, an armchair, a lounger, a bed (furniture), a bed, a couch or the like.

[0017] The frame element can, in principle, be any structure partially or entirely formed from an elastically deformable material. In particular, the frame element can be partially or entirely formed from foam, viscoelastic foam, polyurethane foam, or the like.

[0018] The frame element and the compartment formed therein can form a frame for the adjustment device. For example, the frame element and / or the compartment can be designed such that the adjustment device is encircled and / or enclosed by the frame element on the underside and on all four sides. The adjustment device can thus be integrated, accommodated, and / or arranged in the frame element. This allows the adjustment device to be protected against mechanical damage and / or other environmental influences, such as water or moisture penetration.

[0019] In the context of the present disclosure, the compartment can refer to a chamber, a space, an opening, a recess, and / or a depression. It is conceivable that the compartment has substantially the same width, height, and depth as the adjustment device, such that the adjustment device is held on one or more flanks by the frame element and / or in the compartment. In this way, movements of the adjustment device can be minimized, and the adjustment device can be padded and / or protected by the frame element. In addition to the adjustment device, the cover layer is also arranged in the compartment. The cover layer and the frame structure are designed such that they leave free, define, and / or delimit the receiving space for the adjustment device between them.The compartment is substantially filled, in particular completely, by the adjustment device and the cover layer, so that a substantially closed outer contour, for example a cuboid-shaped outer contour, of the base element is formed. In particular, the thickness of the cover layer substantially corresponds to the depth of the compartment, in particular in those areas in which no parts of the adjustment device are located. In other words, it can be provided that the cover layer completely fills the compartment at least in some areas, in particular in the direction of a vertical axis of the frame element or the compartment, wherein the vertical axis runs parallel to a thickness of the cover layer. In this way, the base element forms a secure and stable support surface for the reclining furniture or a mattress.

[0020] The first side of the frame element has a base surface. The base surface can be used to place and / or support the base element and / or the lounge furniture on the floor.

[0021] The adjustment device can be a motorized adjustment structure or adjustment arrangement configured to adjust, move, pivot, and / or displace the at least two rail elements of at least one of the at least two rails relative to one another via the at least one drive and the at least one drive mechanism. In particular, the rail elements of one, several, or each rail can be displaced about an axis parallel to the transverse axis of the base element and / or parallel to the at least one cross strut and / or transverse to the longitudinal direction of the base element.A region of the base element between rail elements of the rails that are opposite one another in pairs (in the transverse direction of the base element) can thus be displaced and / or adjusted relative to another region of the base element, for example between further rail elements of the rails that are opposite one another in pairs (in the transverse direction of the base element), for example about an axis parallel to the transverse axis of the base element.

[0022] The at least two rails of the adjustment device can, together with the at least one cross strut, form, for example, the structure or shape of an H and / or a ladder, wherein the two legs of the H-shape can be formed by the at least two rails and a position of the cross strut is arbitrary.

[0023] The drive can, in principle, be any type of electric drive and / or electric motor. The drive can be powered by an energy storage device and / or a power cable. Power can also be supplied via solar cells, photovoltaics, and / or energy harvesting.

[0024] Alternatively or additionally, the drive can be supplied with electrical energy inductively. For example, the base element can have one or more inductive receivers, such as one or more receiving coils, which can be inductively coupled to an external inductive supply device.

[0025] The cover layer can generally refer to a layer of elastically deformable material that can be arranged on the frame element. The cover layer can be made of the same material as the frame element or of a different material. In particular, the cover layer can be formed from a foam material, a foam, a viscoelastic foam, polyurethane foam, or the like.

[0026] The cover layer can, in particular, be dimensioned and configured such that it essentially delimits and / or closes off at least the compartment. "Essentially" can mean, for example, that one or more access points can be provided so that a user can reach components of the adjustment device. However, the compartment can also be completely delimited and / or closed off by the cover layer on the second side of the frame element. Likewise, the compartment can be delimited by the frame element and the cover layer. The cover layer can generally protect the adjustment device from external influences or impacts.

[0027] The cover layer can in particular have a base area that is essentially identical to the frame element and / or a floor plan that is essentially identical to the frame element, so that the cover layer can be laid, arranged and / or supported almost over its entire surface and / or flush with the frame element.

[0028] The thickness or strength of the cover layer can be constant across its surface or variable. For example, the cover layer in the compartment area can have a different thickness, such as a greater or lesser thickness, than other areas of the cover layer.

[0029] The cover layer preferably has three functionally separate regions or subregions with respect to their respective transverse extension. For example, the cover layer can have a head pivot region, a drive region, and a foot pivot region, arranged in succession along the longitudinal axis. The drive region is preferably arranged between the head pivot region and the foot pivot region. In other words, the head pivot region, the drive region, and the foot pivot region follow one another along the longitudinal axis of the base element or the cover layer.

[0030] The base element and thus also the frame element preferably has a length, i.e. a longitudinal extension, of between 1800 mm and 2200 mm, preferably between 1900 mm and 2100 mm, for example 2000 mm. The cover layer preferably has a length, i.e. a longitudinal extension, of between 1300 mm and 1600 mm, preferably between 1400 mm and 1500 mm, for example 1485 mm or 1480 mm. The compartment in the frame element preferably has a length, i.e. a longitudinal extension, of between 1400 mm and 1700 mm, preferably between 1500 mm and 1600 mm, for example 1570 mm. An extension of the frame element in the longitudinal direction from the center of the shaft tunnel to the end of the head pivoting range is preferably between 900 mm and 1100 mm, for example 980 mm.An extension of the frame element in the longitudinal direction from the center of the shaft tunnel to the end of the foot pivoting range is preferably between 900 mm and 1100 mm, for example 1020 mm.

[0031] The base element, and thus also the frame element, preferably has a width, i.e., a transverse extension, of between 800 mm and 1200 mm, preferably between 900 mm and 1100 mm, for example, 1000 mm or 900 mm. The cover layer preferably has a width, i.e., a transverse extension, of between 500 mm and 800 mm, preferably between 600 mm and 700 mm, for example, 650 mm or 600 mm.

[0032] The frame element preferably has a thickness, i.e., an extension in the direction of the vertical axis, of between 80 mm and 110 mm, preferably between 90 mm and 100 mm, for example, 95 mm. The cover layer preferably has a thickness, i.e., an extension in the direction of the vertical axis, of between 70 mm and 100 mm, preferably between 80 mm and 90 mm, for example, 85 mm.

[0033] Particularly with these thicknesses, it is ensured that the base element, together with thin mattresses of typical or commercially available dimensions, has a thickness essentially the same as a thick mattress of typical or commercially available dimensions. For example, in a double bed, a reclining furniture item according to the present embodiments can be used on one side and a high or thick mattress on the other side without creating a significant or unpleasantly noticeable height difference between the mattresses or double bed sides. This increases the flexibility of use of the base element according to the invention and enhances user comfort.

[0034] The head pivoting area and the foot pivoting area of ​​the cover layer are particularly designed to be moved along with rail elements of the drive mechanism and, in doing so, to be pivoted relative to the drive area of ​​the cover layer. In other words, the cover layer is arranged in the compartment of the frame element such that both the head pivoting area and the foot pivoting area of ​​the cover layer can be pivoted by the rail elements of the drive mechanism, in particular relative to the drive area of ​​the cover layer. In order to enable typical shapes of the base element or a piece of reclining furniture and / or a mattress lying on the base element that are comfortable for a user, the head pivoting area of ​​the cover layer can have a greater extension in the longitudinal direction of the base element than the foot pivoting area.

[0035] For example, the head pivot range can extend twice, three times, or four times as long in the longitudinal direction of the base element as the foot pivot range. In this way, a mattress or reclining furniture formed via the head pivot range of the base element can comfortably support the entire back, neck, and back of the head of a user. On the other hand, the foot pivot range, which is shorter in the longitudinal direction, enables support, particularly under the knees or in the back of the knees.

[0036] As already mentioned, the compartment of the frame element is essentially completely filled by the adjusting device and the cover layer. The cover layer is therefore shaped in particular in such a way that it does not completely fill the compartment, but leaves the receiving space for the adjusting device free. For this purpose, the cover layer preferably has a shape that is complementary to the adjusting device arranged in the compartment. For example, it can be provided that the drive region of the cover layer is designed to be recessed relative to the head pivoting region and the foot pivoting region in the transverse direction or in the direction of the transverse axis, in particular on both sides. In other words, the head pivoting region and the foot pivoting region of the cover layer preferably project beyond the drive region of the cover layer in the transverse direction or in the direction of the transverse axis on both sides. The extension of the head pivoting region and the foot pivoting region in the transverse direction orin the direction of the transverse axis is therefore greater than the extension of the drive area in this direction. On both sides means that both end faces of the drive area of ​​the cover layer, which are spaced apart from one another in the transverse direction, each form a step to the end faces of the head pivot area and the foot pivot area, which are spaced apart from one another in the transverse direction and border the drive area. Viewed in the transverse direction, the drive area therefore forms a constriction or taper of the cover layer. Overall, the cover layer therefore has an hourglass shape or is hourglass-shaped, with the narrowest point in the transverse direction being formed by the drive area.

[0037] The head pivoting area and the foot pivoting area can in turn each be subdivided into further areas which have a different extent in the transverse direction. For example, it can be provided that the head pivoting area has a first rail area adjacent to the drive area and a first filling area adjacent to the first rail area. Analogously, the foot pivoting area can have a second rail area adjacent to the drive area and a second filling area adjacent to the second rail area. Preferably, the first and the second rail area are each designed to be recessed in the transverse direction or in the direction of the transverse axis compared to the first and the second filling area, in particular on both sides. In the longitudinal direction of the base element orThe cover layer is therefore followed by the first filling area of ​​the head pivoting area, the first rail area of ​​the head pivoting area, the drive area, the second rail area of ​​the foot pivoting area, and the second filling area of ​​the foot pivoting area. The extension of the respective sub-areas decreases gradually in the transverse direction until the drive area, which has the smallest extension in the transverse direction, and then increases again. In other words, the drive area of ​​the cover layer is designed to be recessed relative to the first and second rail areas in the transverse direction or in the direction of the transverse axis, in particular on both sides. The corresponding recesses or recesses in the cover layer ensure that there is sufficient space for the adjustment device and the drive mechanism in the compartment, i.e. the receiving space.For example, the drive of the adjustment device is arranged longitudinally at the level of the drive area of ​​the cover layer. The rails of the drive mechanism, in turn, are arranged longitudinally at the level of the rail areas. This means, in particular, that the drive of the adjustment device is aligned with the drive area in the transverse direction, while the rails of the drive mechanism are aligned with the rail areas in the transverse direction. In this way, the adjustment device is arranged in the compartment or receiving space between the frame element and the cover layer.

[0038] In order to accommodate the at least one shaft or two shafts of the adjustment device, described in more detail below, the cover layer preferably has a channel designed as a shaft tunnel in the drive region. The shaft tunnel or channel extends in the transverse direction or in the direction of the transverse axis across the entire cover layer. In other words, the channel is continuous through the entire cover layer. It therefore leads from one end face of the drive region of the cover layer to the end face of the drive region of the cover layer spaced apart in the transverse direction. The shaft tunnel or channel is expediently located on the drive side of the cover layer, i.e. on the side of the cover layer facing the adjustment device.

[0039] As already mentioned, the head pivoting area and the foot pivoting area should each be movable or pivotable relative to the drive area of ​​the cover layer. To facilitate this mobility and also to enable it to be permanently non-destructive, it is preferred that the cover layer has a pivoting groove between the drive area and the head pivoting area and / or between the drive area and the foot pivoting area. The pivoting groove therefore forms a kind of joint between the respective sections of the cover layer.

[0040] The pivot groove can, for example, comprise at least one cut in the cover layer in the direction of the vertical axis. The cut preferably extends parallel to the transverse direction or in the direction of the transverse axis across the entire cover layer. Furthermore, the cut preferably extends over at least half, preferably at least 75%, of the thickness of the cover layer. The cut is preferably located on the drive side of the cover layer, i.e., on the same side as the shaft tunnel or channel.

[0041] In order to further increase the mobility or pivotability of the head pivoting area and the foot pivoting area relative to the drive area, it is preferably provided that the pivoting groove has at least one notch in the cover layer which forms an angle of between 30° and 60°, preferably between 35° and 55°, in particular between 40° and 50°, for example 45°, with the vertical axis, and which extends parallel to the transverse direction or in the direction of the transverse axis over the entire cover layer. This angled notch is preferably provided together with the notch in the direction parallel to the vertical axis. For example, two angled notches can be provided together with the notch parallel to the vertical axis. At least one of the or preferably all of the angled notches preferably begins at or in the notch parallel to the vertical axis and extends away from it into the cover layer at the angle specified above.For example, two angled notches can be arranged opposite each other, parallel to the vertical axis, and extend from this notch into the cover layer. In this way, the pivot groove preferably comprises a total of three notches in the cover layer, with all three notches being located on the drive side of the cover layer.

[0042] Preferably, the pivot groove also extends through the frame element, in particular as a direct continuation of the pivot groove in the cover layer. In other words, the pivot groove runs through both the frame element and the cover layer. This ensures that the entire base element has the mobility provided by the pivot groove. Preferably, the pivot groove of the cover layer also continues through the frame element, in particular across the entire frame element in the transverse direction or in the direction of the transverse axis. For example, the pivot groove can be created simultaneously in the frame element and in the cover layer, in particular when the cover layer is formed by cutting out the frame element, in particular by cutting out the compartment in the frame element, as explained in more detail below.In this case, the pivot grooves can be inserted before cutting out the cover layer from the compartment and thus automatically extend in the correct position through both the frame element and the cover layer. The cover layer is preferably formed from or consists of a single, one-piece base body. This applies in particular to the entire head pivot area, drive area, and foot pivot area. In particular, the cover layer or its base body consists of a foam material or one of the foam materials mentioned herein. The entire cover layer is therefore preferably a single, coherent part made of a uniform material. It is therefore, in particular, not designed to be multi-part or composed of multiple parts.

[0043] Particularly preferably, the cover layer and the frame element are formed from the same material, wherein the cover layer is formed as a cutout from the frame element, in particular from the compartment of the frame element. In other words, the cover layer and the frame element are manufactured as a single part, for example as a single foam block. The compartment is then cut out of the frame element, with the resulting cutout forming the cover layer. The further, step-shaped recesses described above are then cut out of the cover layer, creating the final cover layer. This also creates the free space between the cover layer and the frame element, i.e., the receiving space for the adjustment device.

[0044] The compartment preferably penetrates the frame element or the foam base body of the frame element completely in the direction of the vertical axis or in the direction of the thickness. This makes the compartment particularly easy to manufacture. On the other hand, however, the compartment must also be closed on the side opposite the cover layer (i.e., the first side) in order to fix the adjustment device in the compartment or in the receiving space. It is therefore preferred that the frame element has a base on the first side, wherein the base preferably comprises a textile, in particular a nonwoven material. The base is attached to the first side of the frame element, i.e., the side of the frame element or base element facing the floor, of the frame element, for example by gluing. The base closes the compartment or the receiving space of the frame element on the first side.Therefore, the base layer, the adjusting device and the cover layer follow one another along the vertical axis from the floor side to the support surface for a mattress of the base element in the area of ​​the compartment of the frame element. The frame element itself merely surrounds or runs around the compartment. The base layer is also preferably designed or constructed in such a way that the mobility or pivotability of the base element is enabled without restriction by the adjusting device. For this purpose, the base layer can, for example, have a notch that extends across the entire frame element in the transverse direction or in the direction of the transverse axis. The notch in the base layer is arranged in particular between, preferably centrally between or in the middle between, the pivot grooves. The notch can be designed in such a way that it completely separates the base layer into two parts.In this way, the two parts of the base can move relative to each other without transferring tensile forces to each other, which may arise, for example, from the different areas of the cover layer or the base element pivoting relative to each other.

[0045] As already mentioned, the adjusting device is particularly designed to deform, for example, a mattress lying on the base element. The shape into which the mattress is brought by the adjusting device should then be maintained, for example when a user is lying on the mattress. In this respect, the adjusting device is preferably designed to withstand compressive forces acting on it, for example from a user lying on a mattress on the base element, in such a way that these compressive forces do not cause or result in any displacement or pivoting of the at least two rail elements of the rails relative to one another. On the other hand, it is preferred that the base element, and therefore also a mattress lying on the base element, can be moved at least back to a neutral starting position even if the power supply to the adjusting device is interrupted.For this purpose, it is preferably provided that the adjusting device has a manually releasable emergency release, after which the at least two rail elements of each rail can be manually displaced against one another. In other words, after the emergency release has been released, the adjusting device and thus a mattress lying on the base element can be moved by compressive forces into a neutral starting position in which the rail elements of each rail are arranged parallel to one another or do not form an angle to one another. In other words, the neutral starting position is a position in which the base element and thus a mattress lying on the base element is arranged flat. In this way, the mattress can also be adjusted into a position typically used for sleeping during a power failure.

[0046] The emergency release is preferably accessible to a user from outside the base element. Since the emergency release acts on the drive mechanism of the adjusting device, this is typically also provided on the drive mechanism or on the adjusting device. An extension is therefore preferably provided which makes the emergency release accessible from outside the base element. For example, the emergency release is preferably connected to a pull actuator which extends from the adjusting device outwards from the frame element. The emergency release is preferably designed so that it can be activated manually via the pull actuator. For example, the pull actuator can be a cord, a string or something similar via which tensile forces can be transmitted to the emergency release. The emergency release can thus be activated or released by pulling on the pull actuator.

[0047] According to one embodiment, the adjustment device of the base element further comprises a control unit configured to actuate and / or control the drive. In particular, the control unit can be configured to regulate, control, and / or monitor a direction of rotation and / or a rotational speed of the drive. For example, it can be used to regulate and / or control a direction of movement and / or speed at which the rail elements, the rails, the base element, and / or a mattress placed thereon are adjusted, moved, pivoted, and / or displaced.

[0048] The control unit can generally be a control circuit, a controller and / or a control component. The control unit can, for example, have one or more microcontrollers and / or processors. The control unit can be arranged with the drive and / or other components in a housing or arranged in a separate housing. The control unit can be coupled to the drive of the adjustment device wirelessly or by wire. Alternatively or additionally, the control unit can also be integrated and / or arranged in one of the rails. In particular, with a waterproof or water-resistant design of the base element or at least a part thereof, a communication connection between the drive and the control unit can be established via a cable.

[0049] Optionally, the control unit can have a housing, in particular a waterproof and / or hermetically sealed housing. This allows the control unit and / or its electronics to be protected against environmental influences, such as water, moisture, or mechanical influences. The adjustment device and / or the control unit can optionally have a data memory in which one or more predefined positions of the rail elements relative to one another can be stored.

[0050] According to one embodiment, the adjustment device of the base element is at least partially waterproof and / or hermetically sealed. All or some of the components or elements, in particular the drive and / or the drive mechanism, of the adjustment device can be waterproof. In particular, optionally present connections between the control unit and the drive, between the drive and the drive mechanism, and / or between the drive and an optional power supply can be waterproof. An at least partially waterproof design of the adjustment device can, in particular, enable use of the base element outdoors or in humid environments or environments with stressful environmental influences, such as in swimming pools, on the beach, in lounges, in clubs, in public institutions, or the like.

[0051] For example, one or more optional cables, such as a power supply cable and / or a cable between the drive and the control unit, can be insulated with a protective, waterproof sheath. Alternatively or additionally, cable connectors can be waterproof.

[0052] Alternatively or additionally, one or more cable bushings between components of the adjustment device and / or the base element can be designed to be watertight. For example, at least one sealing element can be provided on at least one cable bushing, which sealingly encloses the cable routed through the cable bushing at least along a portion of the outer circumference of the cable. Alternatively or additionally, one or more cable bushings can be mechanically reinforced, for example, by means of an eyelet.

[0053] Alternatively or additionally, the control unit, control circuit, drive and / or drive mechanism can be protected, in particular waterproof, in one or more housings.

[0054] It is conceivable that each component, i.e., mechanical or electronic components, of the adjustment device is housed in a separate housing, or some components are housed in a common housing. Such a housing can be multi-piece or single-piece. In a multi-piece housing, for example, the different parts or sections of the housing can be connected to one another with watertight seals. Cable entry points into the respective housing can also be provided with one or more seals, molded, cast, and / or glued.

[0055] According to one embodiment, the adjusting device further comprises one or more energy storage devices configured to at least partially supply the adjusting device with electrical energy. The at least one energy storage device can, in principle, be any desired energy storage device, such as an accumulator, a battery, a capacitor, or the like. The at least one energy storage device can, in particular, be designed to supply the adjusting device with electrical energy in an energy-autonomous manner over a certain period of time. This can enable flexible use of the base element at any location.

[0056] The at least one energy storage device can be characterized in particular by one or more of the following properties: low self-discharge, short-circuit protection, overcurrent shutdown, deep discharge protection, acoustic warning when the remaining charge is low, visual charge level indicator, LED charging indicator for indicating the charge level, mounting feet, a capacity of at least 1000 mAh, for example 1800 mAh, a short charging time, and a low weight (e.g., between 300 and 1500 grams, in particular around 500 grams). The energy storage device can be adapted to the adjustment device with its performance specifications.

[0057] It is also possible to replace the energy storage device as needed. The at least one energy storage device can be charged via cable, for example. Alternatively or additionally, the energy storage device can also be charged inductively, via energy harvesting, and / or using solar cells.

[0058] For example, the base element may comprise one or more induction receivers, such as one or more receiving coils, which may be inductively coupled to an external inductive supply device in order to charge the energy storage device.

[0059] Optionally, the energy storage device can be housed in one or more housings, in particular a waterproof and / or hermetically sealed housing. Alternatively, the base element can also be designed without an energy storage device or without an energy storage device. In this case, the adjustment device can be operated exclusively via an external power supply, for example, via a power cable.

[0060] According to one embodiment, the adjusting device has a plurality of drives and / or a plurality of drive mechanisms. For example, it can be provided that at least one drive and at least one drive mechanism are provided for one or more pairs of rail elements of the at least two rails that are opposite one another in the transverse direction of the base element. This can enable pivoting and / or displacement in pairs with the necessary force. The individual areas between pairs of opposing rail elements can also be displaced relative to one another flexibly and as needed, so that a lying position can be individually adjusted. The use of a plurality of drives and / or drive mechanisms can also increase the load-bearing capacity of the adjusting device.For example, 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, for example when using one or more drives / drive mechanisms.

[0061] The adjustment device and / or a control unit are particularly designed for the continuous adjustment of the rail elements, the base element, and / or the recliner. For example, longitudinally adjacent rail elements, each connected via a joint, can be pivoted by at least 50°, at least 60°, at least 70°, at least 80°, at least 90°, at least 120°, or more (about an axis parallel to the transverse axis of the recliner and / or base element).

[0062] According to one embodiment, the adjusting device has at least one interface and / or communication interface configured to receive and / or send a control signal. The at least one drive is further configured to deform the base element and / or a mattress placed on the base element based on the control signal, at least in some regions, for example in one or more regions of the base element between rail elements arranged opposite one another in pairs in the transverse direction. Alternatively or additionally, the control unit is configured to control and actuate the drive based on the control signal, to set a direction of rotation, a rotational speed, and / or a rotational angle.The control signal can include and / or correlate with information regarding a direction of rotation, angle of rotation, height, speed of rotation, position, and / or shape of the base element that the adjustment device should achieve. Thus, a user of the base element or a piece of reclining furniture with such a base element can deform the mattress, which can be placed on the base element, as desired, individually and according to their needs.

[0063] The interface can basically be any interface that enables a user to send a control signal or receive it in any way. The at least one interface can be wired or wireless. For example, the at least one interface can be designed to connect an operating device, a remote control, a smartphone, a tablet, a PC, a server or the like. The at least one interface can, for example, establish a bus connection, a cellular connection, a WLAN connection, an internet connection, a Bluetooth connection, a radio connection, an optical connection, a cable connection or any other connection(s) with one or more other devices. The interface can in particular be configured to receive a control signal from the operating device and / or a control unit of the base element or piece of reclining furniture.

[0064] According to one embodiment, the at least one interface is a wireless interface configured to wirelessly receive and / or transmit a control signal. For example, the interface can be configured to communicate with a smartphone or a similar data processing device, such as a tablet or the like, and the adjustment device can be controlled and / or actuated via an app installed thereon.

[0065] For example, a receiver can be provided which receives wireless signals, in particular control signals, from an operating device and forwards them to the control device or control unit. The receiver can be connected to the control unit, for example, via a cable connection. The cable connection is preferably routed through a cable duct, so that the control unit is arranged inside the frame element and the receiver is arranged outside the frame element. If the receiver is located outside the frame element, the reception quality of the control signals is increased by the receiver. Furthermore, the receiver can also be used simultaneously for the power connection. The receiver can therefore have a connection, for example a socket or a plug, which is designed for connection to an external power source, for example a socket.The cable connection between the receiver and the control unit can therefore be used simultaneously for signal transmission and power supply. In particular, both the control unit and the adjustment device are supplied with power via the receiver and the cable connection. Particularly preferably, the receiver is also arranged outside of any existing covers, in particular in such a way that the receiver is accessible to a user from the outside when the base element is fully assembled and ready for use, for example, to connect and / or disconnect the connection to the external power source.

[0066] According to one embodiment, the base element further comprises an operating device which is configured to send and / or receive a control signal wirelessly and / or via cable to the adjusting device, the at least one drive and / or a control unit of the adjusting device. The operating device can function or be designed as a type of wired and / or wireless remote control and enable convenient operation and / or actuation of the adjusting device for the user. In particular, if the base element or at least a part thereof is waterproof or water-resistant, a communication connection between the operating device and the adjusting device, the at least one drive and / or the control unit can be established via a cable.

[0067] An operating device can essentially be any device that can be used by a user to send or receive a control signal. This can be a smartphone, a tablet, a remote control, or the like. The sending of a control signal can be triggered, for example, by the push of a button, gesture control, via a display, or via a voice command by the user. The operating device can be connected to the base element via cable and / or wirelessly. The connection to the operating device can be waterproof. The operating device itself can also be waterproof, for example as a waterproof remote control. Alternatively or additionally, the control signal can be sent or received wirelessly, for example via a mobile phone interface on the operating device. Remote control via the Internet, for example via an app or a web interface, is also conceivable.Preferably, the operating device is uniquely and permanently assigned to the adjustment device or coupled to it. The assignment or coupling of the operating device, for example, a remote control, to the adjustment device is designed such that it is retained even after an interruption in the power supply to the adjustment device and / or the operating device. The corresponding assignment of the operating device can be stored, for example, in a memory of the control unit and / or a memory of the operating device.

[0068] According to one embodiment, the drive mechanism coupled to the at least one drive comprises a cable pull mechanism and / or a gear mechanism. The drive mechanism can be at least partially, in particular completely, accommodated, integrated, and / or arranged in one or more rail elements and / or the at least one cross strut. This allows for a compact design and protection of the adjustment device. Alternatively or additionally, the drive mechanism can be at least partially accommodated in a housing.

[0069] The rails and / or the rail elements can in particular be made of a robust material, such as plastic, fiber-reinforced plastic, metal, wood or the like.

[0070] According to one embodiment, at least one longitudinal support strut is arranged on each of the at least two rails to extend the respective rail. For example, a longitudinal support strut can be arranged at one or both ends of the rails, such as a head end and / or a foot end 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, or wood. A wooden construction can be particularly advantageous.

[0071] The area of ​​one or more regions of the base element and / or a mattress placed thereon can advantageously be enlarged in the longitudinal direction of the base element via the longitudinal support struts, since regions can be displaced between longitudinal support struts lying opposite one another in pairs in the transverse direction.

[0072] The longitudinal support struts can be mechanically connected and / or coupled to the respective rail or rail element. Plug-in, press-fit, and / or snap-in connections are conceivable, but other connections such as bolts, screws, and / or adhesive connections are also possible.

[0073] According to one embodiment, an intermediate layer is arranged between each of the rails and the frame element, the base surface and / or the cover layer of the frame element, such that the rails and the frame element, the base surface and / or the cover layer are separated from one another by the intermediate layer. The intermediate layer can comprise any desired material, for example textile material, fabric, cloth, plastic, or other materials. The intermediate layer can advantageously protect the frame element against influences from the rails. If, for example, the rails are made of wood and the frame element of foam, the foam can be damaged upon contact with the wood and, for example, become porous. Such material impairments can be effectively prevented by the intermediate layer.

[0074] The intermediate layer can refer to a separate material layer or ply. Alternatively or additionally, the intermediate layer can refer to an outer material layer, a varnish and / or a coating of the rails, the frame element, the base surface and / or the cover layer of the frame element. For example, the intermediate layer can be applied in the form of a varnish or the like to the frame element, the rails, the cover layer and / or the base surface. Alternatively or additionally, the intermediate layer can refer to an adhesive layer. For example, the rails can be at least partially glued to the frame element, whereby the bond between the frame element and the rails can form the intermediate layer.

[0075] According to one embodiment, the longitudinal support struts arranged on each of the two rails are coupled to one another and / or spaced apart from one another via at least one transverse support strut. This allows the regions between longitudinal support struts located opposite one another in the transverse direction to be supported by the at least one transverse support strut. Multiple transverse support struts can also be provided per region.

[0076] It can be provided that the longitudinal support struts extend the same distance in the longitudinal direction on opposite sides of the adjustment device. In other words, the longitudinal support struts can be designed symmetrically in the longitudinal direction with respect to the adjustment device. However, it is preferably provided that the longitudinal support struts on opposite sides of the adjustment device have different extensions in the longitudinal direction. In other words, it is preferred that the longitudinal support struts are designed asymmetrically in the longitudinal direction with respect to the adjustment device.

[0077] For example, it is preferred that the longitudinal support struts on the side of the head pivot area of ​​the cover layer have a longitudinal extension that is greater than the longitudinal extension of the longitudinal support struts on the side of the foot pivot area of ​​the cover layer. For example, the longitudinal support struts on the side of the head pivot area of ​​the cover layer preferably have a longitudinal extension that is at least twice, preferably at least three times, in particular at least four times as great as the extension of the longitudinal support struts on the side of the foot pivot area of ​​the cover layer. In this way, particularly comfortable shapes of a mattress lying on the base element can be adjusted particularly easily. The cover layer extends longitudinally over the entire extension of the longitudinal support struts.Therefore, the above-mentioned statements regarding the extension of the longitudinal support struts in the longitudinal direction also apply to the cover layer in a figurative sense.

[0078] It is preferably provided that the longitudinal support struts are adjustable in length on at least one side. In particular, the length of the longitudinal support struts should be able to be reduced in order to simplify the transport of the base element. It can therefore be provided, for example, that the longitudinal support struts on the side of the head pivoting area of ​​the cover layer and / or the longitudinal support struts on the side of the foot pivoting area of ​​the cover layer have two parts in the longitudinal direction which are connected to one another via one or more hinges. The hinge or hinges are in particular designed such that one part of the longitudinal support struts can be pivoted into a parallel position with the other part. In other words, the two parts of the longitudinal support struts can be adjusted between a lying position and a transport position.In the lying position, the parts of the longitudinal support struts are arranged one behind the other in such a way that the longitudinal support struts have the greatest possible extension or total length. In the transport position, however, the parts of the longitudinal support struts are arranged parallel to one another in such a way that the longitudinal support struts have the smallest possible extension or total length. In other words, one part of the longitudinal support struts can be folded over until it rests against the other part, for example by 180°. This design has the advantage that the base element has a smaller overall girth or packing size by folding in part of the longitudinal support struts. The base element, including the adjustment device, can thus be sold in a single, normal shipping package. This means that shipping by a freight forwarder or shipping in more than one, for example two, packages is not necessary.Savings on shipping costs can reduce delivery times and overall costs for the end customer. The base element including the adjustment device can therefore be shipped in a package measuring approximately 55 cm long, 105-110 cm wide, and 60 cm high.

[0079] According to one embodiment, the at least one drive is arranged on one of the at least two rails and coupled via at least one shaft to at least one further rail arranged opposite one another. For example, the drive mechanism can comprise the shaft, and at least one drive mechanism can be arranged in each rail, for example a gear and / or cable mechanism. The drive can actuate one of the drive mechanisms in one of the rails, and a rotation of the drive can be transmitted via the shaft to the drive mechanism located in the oppositely arranged rail. In this way, both rails or rail elements of both rails can be moved by just one motor or drive. This can, in particular, enable a compact and lightweight design of the base element.

[0080] Preferably, the at least one shaft is arranged in the shaft tunnel of the cover layer described above. If the adjustment device has multiple shafts, for example, two shafts, all shafts are preferably arranged in the shaft tunnel of the cover layer. The shaft tunnel therefore represents a part of the receiving space that connects the two rails and / or the two drive mechanisms of the adjustment device.

[0081] According to one embodiment, each of the at least two rails has at least three rail elements, which are arranged one behind the other parallel to the longitudinal direction and are coupled to one another in pairs via at least one joint, such that the base element is deformable, movable and / or displaceable in at least three partial regions, which can be formed between rail elements lying opposite one another in pairs in the transverse direction. One or two further regions at one or both ends of the base element can also be displaced in this way, even though no rails may be arranged there. According to one embodiment, the base element further has at least one base cover and / or intermediate cover, which at least partially, in particular completely, encloses the base element and which is designed in particular to prevent a mattress placed on the base element from slipping.The base cover can be made of any material and / or fabric, particularly natural fiber, synthetic fiber, or a mixture thereof. The base cover can also serve to protect the base element.

[0082] It can also be provided that a common cover or base cover is used for the base element and the mattress. For example, the base element and the mattress core can be covered together by a single cover. Preferably, neither the base element nor the mattress core has its own cover. The mattress core is placed directly on the base element and, together with it, is wrapped or enclosed by a cover. The entire assembly consisting of the base element and mattress (hereinafter also referred to as the reclining furniture) therefore preferably has only a single cover. The entire assembly or the reclining furniture is therefore very easy to assemble and can be used immediately.

[0083] Optionally, the base cover can also be at least partially waterproof, for example, on the bottom, sides, and / or top. For example, the base cover can have one or more water-repellent, water-resistant, and / or waterproof layers, such as rubber, latex, a polymer-based material, or another suitable material.

[0084] 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, an upper side, on which a mattress can be placed, and / or an underside for placing the base element on the floor or a support surface, can be at least partially rubberized, coated, and / or provided with latex, for example to prevent a mattress from slipping and / or to prevent or counteract the penetration of water or moisture.

[0085] According to one embodiment, the base cover has an at least partially circumferential closure, in particular a zipper, which can be opened and / or closed for inserting and / or removing the base element. Optionally, the zipper can be at least partially waterproof to prevent or counteract the penetration of water or moisture.

[0086] A further aspect of the present disclosure relates to a piece of reclining furniture with a base element, as described above and below. All above and below disclosures relating to the base element apply equally to the reclining furniture and vice versa. The reclining furniture further comprises a mattress, which is placed and / or arranged with a first side on the cover layer of the base element, such that the mattress is at least partially deformable, displaceable and / or adjustable by at least partially deforming the base element with the adjusting device, and wherein the mattress has a second side opposite the first side, which forms a lying surface of the reclining furniture. The mattress can be arranged and / or placed on the base element in such a way that the mattress is moved and / or displaced in certain areas corresponding to and / or in accordance with and / or in response to a movement of the base element.

[0087] In this way, one or more areas or lying areas of the mattress, which can be arranged above the rail elements arranged in pairs opposite one another in the transverse direction and / or at one or both head ends, can be individually adapted and / or adjusted, in particular continuously, in terms of position, relative position, angle between the areas and / or height. This can offer a considerable level of comfort for a user, as they can vary their position as needed. It also increases the versatility of the reclining furniture, which can therefore 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, a pool chair, a bed, garden furniture, a couch, bedroom furniture or the like.

[0088] Furthermore, the modular design of the reclining furniture can advantageously allow components, such as the base element and the mattress, to be transported separately. On the one hand, this can significantly simplify delivery to customers, return shipping, and transport to different locations by the user. The range of possible uses of the reclining furniture can also be further expanded, for example by enabling the use of different types of mattresses. According to one embodiment, the reclining furniture further comprises at least one reclining furniture cover which at least partially, in particular completely, encloses the base element and the mattress. The reclining furniture cover can advantageously be used to mechanically hold the mattress and the base element together in order to prevent the mattress from slipping on the base element.

[0089] Alternatively or additionally, it may also be provided to connect the base element and the mattress to one another, for example by means of snap fasteners, a hook-and-loop fastener arranged at least partially on the upper side of the base element and / or a base cover, a zipper and / or by means of straps.

[0090] The reclining furniture may have one or more reclining furniture covers. In particular, the reclining furniture may have a first reclining furniture cover designed as a mattress cover and a second reclining furniture cover designed as an outer cover.

[0091] In a preferred embodiment, however, the reclining furniture has only a single cover that surrounds the base element and the mattress or mattress core. Neither the base element nor the mattress core have their own cover, but are arranged exclusively together in a single cover.

[0092] Optionally, an additional intermediate cover can be placed between the mattress cover and the outer cover. Alternatively, or in addition, an additional outer cover can be placed over the outer cover.

[0093] One or more of the covers, in particular the base cover, one or more lounge furniture covers, the mattress cover, the outer cover, another outer cover, and / or one or more intermediate covers, can be at least partially rubberized, coated, and / or provided with latex. In other words, one or more of the covers, in particular the base cover, the lounge furniture cover, the mattress cover, the outer cover, another outer cover, and / or one or more intermediate covers, can be waterproof, water-repellent, and / or water-resistant.

[0094] Optionally, one or more of the covers, in particular the base cover, the lounge furniture cover, the mattress cover, the outer cover, a further outer cover and / or one or more intermediate covers, can have an at least partially circumferential closure, in particular a zipper, which can optionally be at least partially waterproof in order to prevent or counteract the penetration of water or moisture.

[0095] According to one embodiment, the recliner cover has an at least partially circumferential closure, in particular a zipper, which can be opened and / or closed for inserting and / or removing the mattress and / or the base element of the recliner. Optionally, the zipper can be at least partially waterproof.

[0096] According to one embodiment, the at least one reclining furniture cover is designed as a mattress cover, wherein the mattress cover and / or a cover material of the mattress cover is formed at least partially from a spacer fabric, in particular a spacer knit and / or a spacer warp-knitted fabric. Such spacer fabrics can advantageously facilitate air and moisture exchange.

[0097] According to one embodiment, the mattress cover comprises a cover material with at least one upper layer and one lower layer, wherein the upper layer and the lower layer are arranged at least partially one above the other, and wherein at least the upper layer of the cover material is formed from a spacer knit, for example a 3D spacer knit, and wherein a plurality of recesses are formed at least on an outer side of the upper layer facing away from the lower layer.

[0098] The lower layer can be essentially closed and / or knitted in a closed manner, and the cutouts can form openings or perforations in the upper layer. The cutouts can thus be defined by the lower layer. Between the upper and lower layers, the cutouts can optionally be at least partially defined by spacer threads. A contour of the cutouts in the upper layer can be defined by knitting stitches of the 3D spacer fabric on the upper layer.

[0099] The mattress cover therefore uses the advantages of a spacer knit, which, for example, has a spacer structure with stitches, for example at least partially made of knitted monofilament or multifilament spacer threads.

[0100] Furthermore, the cutouts on the outside allow for increased air circulation, increased breathability, and / or increased moisture wicking. The spacer fabric used for the mattress cover differs in several respects from the spacer fabrics regularly used for covers. For example, spacer fabrics are regularly produced on so-called warp knitting machines, while spacer knits are generally produced on a knitting machine, with an additional distinction being made between flat and circular knitting machines. In the production of a spacer fabric, stitches are arranged around a warp (hence the name warp knitting machine). The stitches are arranged vertically. Due to this arrangement of stitches around a warp, the spacer fabric is stable, rigid, inelastic, and non-stretchable.In contrast, the stitches of a spacer fabric are not arranged around a warp, but the stitches themselves can be elastic and stretchable, both horizontally and vertically. In comparison to a spacer knit, a spacer knit can therefore be particularly characterized by being elastic and stretchable in both horizontal and vertical directions, whereas a spacer knit, in comparison, is completely inelastic and non-stretchable. Spacer fabrics are therefore static and rigid fabric structures that exhibit little to no elasticity. Furthermore, a spacer knit has a rigid, hard, and plastic-like feel, whereas a spacer knit can have a textile- or fabric-like and soft feel. Furthermore, in a spacer knit, fiber ends regularly protrude from the surface of the knit, creating a scratchy and rough feel.In contrast, spacer knits generally have a much softer feel, which is sometimes caused by the increased elastic properties of the spacer knit and a much finer processing compared to spacer knits.

[0101] The mattress cover (including a mattress protector) can have a top and / or bottom, each of which can be dimensioned as a sleeping surface for a single user. However, the bottom only provides a sleeping surface optionally and does not necessarily have to be completely closed.

[0102] In the context of the present disclosure, the recesses formed at least on the outer side of the upper layer of the cover material are to be strictly distinguished from the meshes from which the cover material, the lower layer, and / or the upper layer may be formed. Compared to the meshes, the recesses may be larger; for example, the recesses may have a cross-sectional area that may be many times larger (approximately 5 to 100 times or more) than the average cross-sectional area of ​​the meshes of the cover material.

[0103] The cover fabric can generally be two-layered, three-layered, or multi-layered. In particular, the cover fabric can be made and / or formed entirely from spacer knit and / or 3D spacer knit.

[0104] In a two-layer design of the cover material, the upper and lower layers can be at least partially connected and / or knitted with threads from the upper and / or lower layers, for example at specific points. Alternatively or additionally, connecting threads can be used to connect the upper and lower layers. In a three- or more-layer design of the cover material, one or more middle layers of the cover material can be connected and / or knitted with the upper and / or lower layers. Alternatively or additionally, connecting threads can also be used here, which can connect at least two layers of the cover material, for example the upper and lower layers and / or one or more middle layers.

[0105] The mattress cover can be easily produced, for example, on a large circular knitting machine using the so-called 3-way technology with a high throughput and therefore high cost-effectiveness.

[0106] The cutouts can be designed to be open toward the outside, i.e., toward the user, and / or have an outwardly open cross-section. The cutouts can thus denote openings. The cutouts can be advantageous in terms of air exchange and moisture wicking, as well as generally compensating for temperature fluctuations. The cutouts can also provide increased elasticity, which offers a soft feel to the user and can also allow the cover to optimally adapt to the user or head lying on it, without being impaired by brittle spacer threads that are often noticeable in spacer fabrics.

[0107] The recesses formed at least on the outer side of the upper layer can further provide and / or form a mesh structure of the cover material. In other words, the cover material can have a mesh structure, such as a honeycomb mesh structure, with the recesses, at least on the outer side.

[0108] The cutouts in the mesh structure and / or the cover fabric can, for example, be arranged in a regular pattern on the outer side of the cover fabric. In other words, the cutouts can be arranged regularly and / or in a regular pattern. However, an irregular arrangement, for example, forming a pattern, is also conceivable.

[0109] The recesses, such as those open to the outside, can be variable in terms of their geometry, for example round, square, oval, polygonal, elliptical or any other shape in terms of their open cross-section.

[0110] For example, the recesses can be honeycomb-shaped. Alternatively or additionally, the recesses can have a round, rounded, angular, square, rectangular, polygonal, triangular, elliptical, oval, and / or polygonal cross-section.

[0111] According to one embodiment, the upper layer and / or the lower layer of the cover material is at least partially made of a natural fiber.

[0112] The use of natural fibers, which can be contained and / or knitted into the spacer fabric, can increase the sustainability and / or ecology of the mattress cover (hereinafter also referred to as "cover"), for example, because the natural fibers can be obtained from renewable raw materials. Natural fibers can also be characterized by increased resilience and / or durability. Furthermore, natural fibers can result in a pleasant, soft feel for the user. Natural fibers can also be characterized by increased skin compatibility, breathability, and / or odor neutrality. Furthermore, natural fibers can enable cost-efficient production of the mattress cover.

[0113] According to one embodiment, the natural fiber is an animal hair fiber, a wool fiber, a cotton fiber, a hemp fiber, a eucalyptus fiber, a bamboo fiber, a linen fiber, a wood fiber, a viscose fiber, a flax fiber, a silk fiber, a plant fiber, or a combination thereof. Such natural fibers can be characterized by increased sustainability, odor neutrality, skin compatibility, durability, and / or robustness compared to synthetic fibers.

[0114] According to one embodiment, the upper layer, the lower layer, and / or one or more middle layers of the cover material have a weight fraction of natural fibers, approximately based on the respective layer or the entire cover material, of 2% to 99%, for example at least 5%, at least 10%, at least 15%, at least 20%, and / or at least 25%. At least 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, or 75% of natural fibers is also conceivable.

[0115] According to one embodiment, the proportion, for example the weight proportion and / or volume proportion, of natural fibers, for example based on the respective layer or the entire cover material, in the upper layer is greater than the proportion, for example the weight proportion and / or volume proportion, of natural fibers in the lower and / or one or more middle layers. For example, the proportion in the upper layer can be at least twice as large as the corresponding proportion of natural fibers in the lower and / or one or more middle layers.

[0116] According to one embodiment, the upper layer consists essentially and / or almost entirely, for example entirely, of natural fibers and the lower layer, as well as optionally one or more middle layers, consist essentially and / or almost entirely, for example entirely, of synthetic fibers.

[0117] According to one embodiment, the upper layer and / or the lower layer of the cover fabric is at least partially formed from textured, twisted yarn, in particular multifilament yarn, for example, from polyester yarn, polyethylene yarn, polyamide yarn, polyethylene yarn, and / or polyamide yarn. This can provide a soft and pleasant feel.

[0118] According to one embodiment, the upper layer and / or the lower layer of the cover material is at least partially formed from monofilament yarn, in particular polyester yarn, smooth polyester yarn, polyethylene yarn, smooth polyethylene yarn, polyamide yarn, and / or smooth polyamide yarn. Forming the cover material from monofilament yarn on the underside of the cover material facing the mattress core or the pillow core can facilitate the removal or insertion of the mattress or pillow core.

[0119] For example, the cover fabric made of spacer knit can be formed of at least two layers, with an upper layer forming the outer surface and a fabric layer forming an inner or lower layer, preferably made of polyester fiber, polyethylene fiber, and / or polyamide fiber. The inner or lower layer can, for example, be a smooth fabric layer, which can also be jacquarded and / or provided with a pattern, for example, onto which the upper layer of the spacer knit made of textured, twisted yarn, in particular multifilament yarn, can be built up towards the outside.

[0120] According to one embodiment, the cover material further comprises a middle layer, which is at least partially and / or at least partially knitted with the upper layer and / or the lower layer. The middle layer can serve to add volume to the cover material. This can also increase sleeping comfort.

[0121] According to one embodiment, the middle layer is at least partially formed from a monofilament yarn, in particular polyester yarn, smooth polyester yarn, polyethylene yarn, smooth polyethylene yarn, polyamide yarn, and / or smooth polyamide yarn.

[0122] According to one embodiment, the middle layer is at least partially formed from a multifilament yarn, for example a textured, twisted multifilament yarn, for example from polyester yarn, polyethylene yarn, polyamide yarn, polyethylene yarn and / or polyamide yarn.

[0123] According to one embodiment, the middle layer is formed at least partially from a natural fiber. This offers the advantages explained above with regard to natural fibers.

[0124] According to one embodiment, the recesses extend at least substantially across a thickness of the upper layer and, optionally, the middle layer. In particular, the recesses can extend completely through the upper layer, so that the recesses can form and / or represent openings in the upper layer.

[0125] The cutouts can, for example, extend at least substantially across the entire thickness of the upper layer, i.e., from the outer side to the inner or lower layer or close to it, for example to enable optimal climate control with regard to air and moisture exchange between the two sides of the cover material. In addition, the depth of the cutout can increase the softness of the upper layer of spacer knit, thus achieving an improved feel. The cover material can also be made of three layers with a middle layer, for example a layer knitted with the upper layer, with a monofilament yarn as filler. This can achieve stabilization and a haptically often desired voluminization of the spacer knit while simultaneously achieving high air and moisture permeability.The monofilament yarn can, for example, be made at least partially of polyester, polyamide and / or polyethylene, but other synthetic fibers can also be used.

[0126] In order to give the outward-facing surface or outer side of the spacer knit a particularly smooth and pleasant feel, the surface or outer side surrounding the recesses can be formed from finer knitting stitches compared to other areas of the outer side.

[0127] According to one embodiment, the upper layer comprises a weight percentage of 50% to 70%, particularly 55% to 60%, of the cover material. Studies have shown that this weight percentage is particularly advantageous in terms of comfort and microclimatization.

[0128] According to one embodiment, the lower layer has a weight proportion of 20% to 30%, in particular 25% to 30%, of the cover material.

[0129] According to one embodiment, a middle layer has a weight proportion of 10% to 20%, in particular 15% to 20%, of the cover material.

[0130] When using a filler, optimal results in terms of air permeability, stabilization and volumization were determined at a weight proportion of 10% to 20%, in particular 15% to 20%, of the middle layer of the cover material.

[0131] According to one embodiment, the cover material has a weight of 250 g / m 2 - 300 g / m 2 This allows the upholstery fabric to offer the required durability while remaining lightweight and easy to handle during production and use.

[0132] According to one embodiment, the cover material is rubberized, coated, and / or provided with latex on at least one side, for example, the outer side, the inner side, the underside, and / or the upper side, for example to prevent the penetration of moisture and / or water. According to one embodiment, the cover material is designed identically on all sides. In other words, the mattress cover can be designed identically on all sides, i.e., on the upper side, on the underside, and on any longitudinal and transverse sides. However, it is also conceivable to design different sides of the cover differently.

[0133] The identical design of all sides can enable particularly simple production, whereby due to the high breathability of the cover material, a ventilation band on the transverse and longitudinal sides, which is often found in known covers, especially mattress covers, can be dispensed with.

[0134] According to one embodiment, the mattress cover has an at least partially circumferential closure, in particular a zipper, which can be opened or closed for inserting or removing a mattress core and / or a pillow core. To enable the insertion and removal of a mattress core or a pillow core, it may be advantageous for the mattress cover to have an at least partially circumferential closure, in particular a zipper.

[0135] Furthermore, handles can be sewn onto the mattress cover to make it easier to handle a mattress covered with the mattress cover and / or the reclining furniture.

[0136] The mattress cover may further be washable, for example at a temperature of 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.

[0137] Another aspect of the present disclosure relates to the use of a mattress cover for a piece of reclining furniture as described above and below.

[0138] Reclining furniture with a mattress cover can prove particularly advantageous for indoor use. Instead of or in addition to the mattress cover, the reclining furniture can also have an outer cover. The outer cover can at least partially, but particularly completely, enclose the base element, the mattress, and optionally the mattress cover.

[0139] Optionally, an additional outer cover can be provided, which can at least partially, in particular completely, enclose the outer cover. The additional outer cover can be designed, for example, analogously to the mattress cover, as described above and below. By providing the additional outer cover, lying comfort for the user can be increased, and protection against water can be ensured by the underlying outer cover and / or an additional cover, in particular the basic furniture cover.

[0140] According to one embodiment, the at least one lounge furniture cover is designed as an outer cover, in particular for use of the lounge furniture outdoors, wherein the outer cover is at least partially waterproof, washable and / or heat-insulating.

[0141] According to one embodiment, the outer cover comprises silicone, rubber, polymer-based material, fiber material, fabric, latex, plastic, leather, synthetic leather, and / or plastic.

[0142] Different materials, colors, and textures are conceivable and / or combinable for the outer cover.

[0143] According to one embodiment, the outer cover has an at least partially circumferential closure, in particular a zipper, which can be opened and / or closed for inserting and / or removing the mattress and / or the base element of the recliner, wherein the closure is at least partially waterproof. This can be particularly advantageous for use of the recliner outdoors or in harsh environments.

[0144] According to one embodiment, the reclining furniture further comprises an anti-slip layer or ply, which is deposited on the cover layer of the base element and arranged between the base element and the mattress. The anti-slip layer or ply is designed to secure the mattress on the base element against slipping. The anti-slip layer or ply can comprise, for example, rubber, silicone, latex, or the like.

[0145] As already mentioned, it can be provided that both the base element and the mattress are jointly enclosed exclusively by a single cover, for example the reclining furniture cover. Neither the base element nor the mattress preferably have a further, separate cover. The mattress can therefore be a mattress core. Overall, the reclining furniture therefore preferably has only a single cover, for example the reclining furniture cover. In other words, both the base element and the mattress are free of further covers, in particular covers that each exclusively surround the base element or the mattress. In this way, the reclining furniture has a particularly simple and cost-effective construction. The shared cover ensures that the base element and the mattress cannot move or shift against each other, so that the reclining furniture as a whole is held together.

[0146] The reclining furniture cover preferably has a layer of the cover material described above that completely surrounds the base element and the mattress. This is therefore preferably designed as a spacer knit with the layers, recesses, and other features described herein. Furthermore, the reclining furniture cover has, in addition to the cover material, at least one padding layer and / or at least one underlay, particularly on the inner side that is in contact with the base element. The padding layer and / or the underlay are therefore arranged at least on the underside of the reclining furniture or the reclining furniture cover. The underside is the side on which the reclining furniture is placed on a floor or a bed frame, for example with or without a slatted frame. At the same time, the underside is the side whose inner side comes into contact with the base element.The upholstery layer and / or the base is arranged particularly on the contact surface of the reclining furniture cover with the base element.

[0147] In this case, it is preferably provided that the upholstery layer and / or the underlay are arranged exclusively on the side of the reclining furniture cover on which the base element is located, i.e. on the underside just described. In particular, the upholstery layer and / or the underlay at least partially surround the base element both on the underside and the end faces of the reclining furniture. In other words, the upholstery layer and / or the underlay form a type of tub in which the base element is arranged. They are located between the base element and the underlay on which the reclining furniture lies, but are also pulled upwards on the end faces of the reclining furniture, which extend parallel to the vertical axis, so that they at least partially accommodate the base element. In this case, they extend in the direction of the vertical axis in particular as far as the base element, for example a maximum of as far as the base element.At the mattress level, the upholstery is free of the upholstery layer and / or base. This allows the base element to be advantageously supported by the additional layers, while the tactile properties of the upholstery fabric and mattress remain unchanged for a user lying on the upholstery.

[0148] The padding layer preferably comprises padding. For example, the padding layer may comprise or consist of polyester padding. Additionally or alternatively, the base layer may comprise or consist of a nonwoven material.

[0149] In the area of ​​the loveseat cover described above, especially on the underside, the cover fabric, the upholstery layer, and the underlay preferably follow one another from the outside inward. The underlay therefore covers the upholstery layer inward toward the base element, while the entire outer side of the loveseat cover is formed or covered by the cover fabric.

[0150] According to one embodiment, the mattress has at least one head support area for supporting a head, at least one neck support area for supporting a neck, at least one shoulder support area for supporting shoulders, at least one lordosis support area for supporting at least part of a spine and at least one pelvic support area for supporting a pelvis of the user.

[0151] According to one embodiment, the head support area, the neck support area, the shoulder support area, the lordosis support area and the pelvic support area have, at least partially, different profiles on the first and / or second side of the mattress. Such profiles can, for example, be profilings and / or structurings, so that a hardness, compression hardness and / or a degree of hardness of at least some of the individual support areas, i.e. head support area, neck support area, shoulder support area, lordosis support area and / or pelvic support area, differ from one another and / or so that the compression hardnesses of the mattress (or mattress elements of the mattress) differ from one another at least in some areas. The mattress can furthermore optionally be a mattress and / or reversible mattress, which can provide different degrees of hardness.

[0152] For ergonomic and comfortable lying, the mattress (or mattress elements thereof) can be divided into different support areas and / or zones. In particular, the mattress can have one or more head support areas, one or more neck support areas, one or more shoulder support areas, one or more lumbar support areas, and one or more pelvic support areas. The different support areas can have different compression hardnesses, degrees of firmness, and / or elasticity, so that the user sinks into the outer surface to different depths in the respective support area or is supported by it. The different support areas can also take into account the user's weight distribution over at least part of the first and / or second outer surface.For example, the different compression hardnesses of the support areas can be used to take into account the fact that the user's head is lighter than their pelvis. The different compression hardnesses in the various support areas can also ensure that the user's spine or back is straight, for example, when lying on their side, or maintains the typical S-shape, such as when lying on their back.

[0153] The different compression hardnesses in the respective support areas can be achieved by using different materials, such as mattress foam and / or polyurethane foam of varying hardness or softness, by using different profiles and / or by structuring the first and / or second outer surface. Such profiles can include, for example, grooves, beads, ridges, notches, cutouts, transverse grooves, depressions, channels, notches, and / or recesses.

[0154] According to one embodiment, the mattress (or mattress elements thereof) comprises a first half and a second half relative to a central transverse axis and / or a central transverse plane, which are arranged one behind the other along a longitudinal axis of the mattress. In each half, the mattress (or one or more mattress elements) comprises a head support area, a neck support area, a shoulder support area, a lumbar support area, and a pelvic support area. The two head support areas, neck support areas, shoulder support areas, lumbar support areas, and pelvic support areas of the mattress (or one or more mattress elements) can thus be arranged mirror-symmetrically relative to the central transverse axis and / or central transverse plane.

[0155] According to one embodiment, the first half and the second half of the mattress (or one or more mattress elements) are symmetrical, in particular mirror-symmetrical, relative to the central transverse axis and / or central transverse plane of the mattress or the reclining furniture. In particular, with regard to the design of the various support areas as well as the structuring and / or profiling of the various support areas, the mattress (or individual mattress elements) can be mirror-symmetrical.

[0156] The support areas can, for example, be formed in each of the first and second halves of the mattress (or one or more mattress elements) as described below. One head support area extends from each end of the mattress in the direction of the central transverse axis. One neck support area is adjacent to each of the head support areas and extends further in the direction of the central transverse axis. One shoulder support area is adjacent to each of the neck support areas and extends further in the direction of the central transverse axis. One lumbar support area is adjacent to each shoulder support area and extends in the direction of the central transverse axis. One pelvic support area is adjacent to each lumbar support area and extends to the central transverse axis.

[0157] According to one embodiment, the first and / or second side of the mattress has at least one recess and / or at least one transverse groove, at least in a partial area. One or more transverse grooves can be formed in the individual support areas. Transverse grooves in different areas can differ, for example, in terms of number, geometry, cross-section, size, depth, or the like.

[0158] The transverse grooves can extend essentially parallel to the transverse axis of the reclining furniture over the entire width of the first and / or second side of the mattress.

[0159] Individual transverse grooves can be perceived as macroscopic depressions, incisions or recesses.

[0160] According to one embodiment, the mattress comprises at least two mattress elements that are at least partially stacked on top of one another. Alternatively or additionally, the mattress comprises at least a first mattress element and a second mattress element that are at least partially stacked on top of one another. The mattress may also comprise more than two mattress elements. The thickness of the mattress elements, measured orthogonally to the longitudinal and transverse axes, may be identical or different from one another.

[0161] According to one embodiment, each of the two mattress elements has an outer surface and a contact surface, wherein the contact surface of the first mattress element is at least partially in contact with the contact surface of the second mattress element, and wherein at least one of the outer surfaces and / or contact surfaces of at least one of the first and second mattress elements has 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 formed additionally or exclusively on one or both of the contact surfaces.

[0162] In particular, profiles can be provided on one of the outer surfaces and the contact surface of each mattress element, which profiles can have different profiles from each other. If a profile is provided on both contact surfaces, the profiles of the two mattress elements can optionally at least partially interlock and / or be designed to correspond to each other.

[0163] According to one embodiment, the outer surface and / or the contact surface of the first mattress element has a first profile, and the outer surface and / or the contact surface of the second mattress element has a second profile, wherein the first profile differs at least partially from the second profile such that a degree of hardness of the first mattress element differs from a degree of hardness of the second mattress element. The profiles can, for example, have different transverse grooves.

[0164] The degree of hardness or compression hardness for the first and second mattress elements can also be influenced, for example, by the choice of material for the respective mattress element. Different types of foam (such as polyurethane foam) can be selected, for example. Furthermore, the degree of hardness can be influenced by corresponding structures, such as grooves, transverse grooves, beads, ridges, incisions, cutouts, depressions, channels, notches and / or recesses, which can be formed, for example, in the first and / or second outer surface and / or the first and / or second contact surface. Furthermore, the connection of the first mattress element to the second mattress element can also be influenced, in particular by the choice and / or design of a profile on at least one of the contact surfaces.Alternatively or additionally, the degree of hardness can vary in the various areas of the mattress element, for example through the choice of material, the profiling and / or structuring of the respective outer surface and / or the design of the contact surface(s). For example, a shoulder support area can be designed somewhat softer than a neck support area, so that the user's shoulder sinks deeper into the outer surface of the mattress than their neck, particularly when the user is lying sideways on the respective outer surface of the mattress element. According to one embodiment, at least one of the first contact surface and the second contact surface has a profile with one or more transverse grooves, at least in a partial area. This can further improve or influence the support properties.

[0165] According to one embodiment, the profile is formed exclusively on the second contact surface of the second mattress element. Alternatively or additionally, no profile is formed on the first contact surface of the first mattress element.

[0166] According to one embodiment, the first contact surface and the second contact surface have profiles that correspond to each other and / or at least partially interlock. For example, the profiles can interlock in a tooth-like manner to secure the mattress elements to each other.

[0167] According to one embodiment, the firmness of the first mattress element is greater than the firmness of the second mattress element. The reverse can also be the case.

[0168] According to one embodiment, at least one, in particular several, transverse grooves extending in the transverse direction of the mattress are formed on the first outer surface of the first mattress element and / or on the second outer surface of the second mattress element between the at least one head support area and the at least one neck support area. The transverse grooves have a T-shaped, trapezoidal, and / or triangular cross-section. The transverse groove can be formed, for example, as a groove, bead, groove, incision, cutout, depression, channel, notch, and / or recess across the entire width in the transverse direction of the mattress (also called a combination mattress).

[0169] In general, at least one transverse groove can be formed in at least one of the head support area, the neck support area, the shoulder support area, the lumbar support area, and the pelvic support area. In general, the profiles in the individual support areas can be provided and / or defined by the transverse grooves or the absence of transverse grooves. Transverse grooves in different support areas can differ from one another in terms of their geometry, their cross-section, the depth of the respective transverse grooves, a dimension, a length, and / or a width. This allows the degree of hardness of the individual support areas to be varied and / or coordinated with one another. One or more transverse grooves can have a drop-shaped, circular, triangular, trapezoidal, round, oval, elliptical, or T-shaped cross-section.In general, a depth of the transverse grooves measured along the vertical axis can be about 1 to 5 cm, and a width of the transverse grooves measured along the longitudinal axis can be about 1 to 4 cm.

[0170] Optionally, one or more transverse grooves can be incorporated into the material of the mattress in such a way that they are at least partially covered on the outside by the material of the mattress.

[0171] According to one embodiment, at least one, in particular several, transverse grooves extending in the transverse direction of the mattress are formed on the first outer surface of the first mattress element and / or on the second outer surface of the second mattress element in the at least one pelvic support region, which transverse grooves have a T-shaped, trapezoidal, and / or triangular cross-section.

[0172] According to one embodiment, at least one, in particular several, transverse grooves extending in the transverse direction of the mattress are formed on the first outer surface of the first mattress element and / or on the second outer surface of the second mattress element in the at least one shoulder support region, which transverse grooves have a round, oval, drop-shaped and / or elliptical cross-section.

[0173] According to one embodiment, a plurality of transverse grooves extending in the transverse direction of the mattress are formed on the first outer surface of the first mattress element in the at least one shoulder support area, each having a round and / or drop-shaped cross-section. The transverse grooves formed in the shoulder support area have identical diameters, cross-sections, and / or sizes. The size of a transverse groove can refer to a dimension measured in the longitudinal direction of the mattress, such as a width, of the respective transverse groove.

[0174] According to one embodiment, a plurality of transverse grooves extending in the transverse direction of the mattress are formed on the second outer surface of the second mattress element in the at least one shoulder support region, each having a round and / or drop-shaped cross-section, wherein at least some of the transverse grooves formed in the shoulder support region have different diameters and / or sizes. The diameters, dimensions, widths, and / or sizes of the transverse grooves can decrease in the direction of the central transverse axis and / or the central plane. A further aspect of the present disclosure relates to the use of a piece of reclining furniture, as described above and below, for lying and / or sitting in an outdoor area, outdoors, and / or in a harsh environment.

[0175] A further aspect of the present disclosure relates to the use of a base element, as described above and below, for deforming and / or adjusting a mattress placed on the base element. 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 top layer.

[0205] Detailed description of embodiments

[0206] Figure 1a shows a base element 100 according to an embodiment in an exploded view. Figure 1b shows an adjustment device 300 of the base element of Figure 1a. Figure 2 shows a plan view of the base element 100 of Figure 1a.

[0207] 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, wherein the compartment 102 is designed and / or dimensioned such that the adjustment device 300 can be accommodated and / or integrated in the compartment 102. The adjustment device 300 is thus at least partially accommodated in the compartment 102.

[0208] The cover layer 101b of the base element is arranged on the frame element 101a. The frame element 101a can be partially or entirely made of foam. Likewise, the cover layer 101b can be partially or entirely made of foam. However, other materials are conceivable. The cover layer 101b can optionally have a cutout 114, which can be designed to provide space for the assembly / disassembly of one or more components of the adjustment device 300. This will be explained in more detail below in connection with Figures 14-17.

[0209] The adjustment device 300, which is configured to deform or adjust the base element 100 and / or a 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 strut 103. Each of the rails 104, 104' extends substantially parallel to a longitudinal axis 107 of the base element 100, and the at least one cross strut 103 extends substantially parallel to a transverse axis 109 of the base element 100.

[0210] Each of the rails 104, 104' has, for example, three rail elements 105a, 105b, 105c, which are arranged one behind the other in the longitudinal direction of each rail 104, 104' and / or parallel to the longitudinal direction 107. The rail elements 105a, 105b, and 105c are each movably coupled to one another via a joint 106 at their ends, so that the rail elements 105a, 105b, and 105c can be pivoted about an axis parallel to the transverse axis 109 via the joints 106.

[0211] In the example of Figures 1a, 1b, and 2, the base element 100 or the adjustment device has two drives 108, 108' and two drive mechanisms 115, 115'. Each drive mechanism can have one or more cable pull mechanisms and / or gear mechanisms, which can be at least partially arranged and / or integrated in one or more rail elements 105a-105c. Furthermore, the adjustment device has two cross struts 103, 103', each of which can be assigned to a drive mechanism 115, 115'.

[0212] A shaft 135 can be arranged in each of the cross struts 103, 103' and coupled to one of the drives 108, 108'. Alternatively, the cross struts 103, 103' can each form a shaft 135.

[0213] The drives 108, 108' are arranged on one of the two rails 104' and can actuate the drive mechanism located in the rail elements of this rail, such as a cable-pull mechanism and / or a gear mechanism. The rotation of the respective drive 108, 108' can be transmitted via the associated shaft 135 or cross brace 103, 103' to the oppositely arranged rail 104 and the drive mechanism located in the rail elements of this rail, such as a cable-pull mechanism and / or a gear mechanism, and actuate it. In this way, regions 117a, 117b, 117c arranged between the rail elements 105a-105c, which are arranged in pairs opposite one another in the transverse direction 109, can be displaced, pivoted, and / or tilted relative to one another.

[0214] To extend the rails 104, 104' in the longitudinal direction 107, a longitudinal support strut 302 is arranged at each end of each rail element 105a, 105c, for example at each head end and / or foot end of each rail 104, 104', of the base element 100. These struts are spaced apart from one another and coupled to one another in the transverse direction 109 via one or more transverse support struts 110. On the one hand, the regions 117a and 117c can be enlarged, the stability of the adjusting device 300 can be increased, and the adjusting device 300 can withstand increased loads. In addition to the regions 117a and 117c, regions projecting beyond the front ends, head ends, and / or foot ends of the adjusting device 300 can also be individually relocated. Thus, in the example of Figures 1a, 1b, and 2, at least three, four, or five differently and individually adjustable regions can be created. More or fewer areas may also be provided.

[0215] The adjustment device 300 further comprises a control unit 310, which is configured to control the adjustment device 300 and / or one or more drives 108, 108'. For example, the control unit 310 can be used to regulate a direction of rotation, a rotational speed, or the like. This can be done via a suitable control signal.

[0216] The control unit 310 further comprises an interface coupled to a receiver 122 via a cable connection 112. The receiver 122 is configured to wirelessly receive control signals from an operating device 120 and to forward them to the control unit 310 via the cable connection 112. The operating device 120 may comprise a user interface, such as a display, buttons, or the like, to control the control unit 310 and / or the adjusting device 300, in particular via the receiver 122. In particular, the operating device 120 is a remote control, a smartphone, a tablet, a PC, a notebook, a server, or the like. Alternatively or additionally, the control unit 310 comprises another and / or additional wireless interface 312 for communicating with the operating device 120, as shown in Figure 2.

[0217] The receiver 122 is particularly designed such that it is connected to the control unit 310 via the cable connection 112. The cable connection 112 can simultaneously establish a power supply 157 (see Figure 20) and a control connection. The power supply 157 preferably supplies both the control unit 310 and the adjustment device 300 with electrical energy. Furthermore, the control signals from the operating device 120 received by the receiver 122 are preferably also forwarded to the control unit 310 via the cable connection 112. The cable connection 112 leads out of the frame element 101a, for example, through a cable feedthrough formed by the pivot groove 147. The receiver 122 is therefore particularly arranged outside the frame element 101a. In this way, the reception of the control signals from the operating device 120 by the receiver 122 is particularly reliable.At the same time, the receiver may have a socket or a plug for connection to an external power source, such as a power outlet.

[0218] Furthermore, the base element 100 optionally has an energy storage device 315, such as a battery or accumulator, for supplying the adjustment device 300 with electrical energy. The energy storage device 315 can be charged, for example, via a cable, which can optionally be routed through the frame element 101a and / or the cover layer 101b. Inductive charging or other techniques are also conceivable.

[0219] Furthermore, components of the adjustment device 300 can be designed to be at least partially waterproof.

[0220] Figure 3 shows a base element 100 according to one embodiment. Unless otherwise described, the base element 100 of Figure 3 has the same elements and features as the base element 100 of Figures 1a to 2.

[0221] The base element 100 of Figure 3 further comprises a base cover 301, in which the frame element 101a, the cover layer 101b, and / or the adjustment device 300 are at least partially, in particular completely, accommodated. The base cover 301 is particularly designed to prevent a mattress 202 placed on the base element 100 from slipping. The base cover 301 can be made of any material and / or fabric, in particular natural fiber, synthetic fiber, or a mixture thereof. The base cover 301 can also serve to protect the base element 100.

[0222] Optionally, the base cover can also be at least partially waterproof, for example, on the underside, the sides, and / or the top. In particular, the base cover 301 can be rubberized, coated, and / or provided with latex, for example, on its outer side, inner side, top side, and / or underside.

[0223] The base cover 301 can be at least partially formed from 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 formed from latex. In particular, a top side, on which a mattress 202 can be placed, and / or an outer side of the base cover 301 can be at least partially rubberized, coated, and / or provided with latex to prevent a mattress 202 from slipping.

[0224] The base cover 301 has an at least partially circumferential closure 303, in particular a zipper 303, which can be opened and / or closed for inserting and / or removing the base element 100. Optionally, the (zipper) closure 303 can be at least partially waterproof.

[0225] The base cover 301 can further comprise one or more cable bushings 350, for example, for passing through a cable of the control unit 310 and / or the operating device 120. Optionally, the cable bushing 350 can be mechanically reinforced, for example, with an eyelet. Further optionally, the cable bushing 350 can be designed to be sealed, at least partially enclose the cable in a sealing manner, and / or comprise a sealing element.

[0226] Figures 4 and 5 each show a reclining furniture 200 according to an embodiment.

[0227] The reclining furniture 200 has a base element 100 on which a mattress 202 with a first side 203 is arranged and / or placed. Opposite the first side 203, the mattress 202 forms a lying surface 205 for a user. The lying surface lies opposite a bottom side 101 of the base element 100. The base element 100 of Figures 4 and 5 can be designed like the base element 100 of the figures described above. The reclining furniture 200 further has at least one reclining furniture cover 204, which at least partially, in particular completely, encloses the base element 100 and the mattress 202. The reclining furniture cover 204 can be designed as a mattress cover 204, as described with reference to Figures 6 to 8. Optionally, the reclining furniture cover 204 and / or mattress cover 204 can be at least partially coated, rubberized and / or provided with latex to prevent water penetration.

[0228] Alternatively or in addition to the mattress cover 204, a further reclining furniture cover 204 in the form of an at least partially waterproof outer cover 204 can also be provided, which can enclose the base element, the mattress and optionally the mattress cover at least partially, in particular completely.

[0229] Optionally, a further outer cover can also be provided, which at least partially, in particular completely, encloses the outer cover 204. The further outer cover can be designed analogously to the mattress cover, as described above and below. Optionally, the further outer cover can also be at least partially coated, rubberized, and / or provided with latex to prevent water penetration.

[0230] One or more of the lounge furniture covers 204 can have an at least partially, in particular completely circumferential closure 206, such as a zipper, which can optionally be at least partially waterproof.

[0231] For transport, two or more transport handles 210, 210' may also be provided on each side of the reclining furniture 200. These can be at least 2 to 10 cm wide or wider and / or at least 5 to 20 cm long or longer, for example, to ensure high stability and high carrying comfort.

[0232] In Figure 4, the reclining furniture 200 is shown in a horizontal position. In Figure 5, however, the individual regions 117a-117c are adjusted and / or displaced by the adjustment device 300, resulting in a total of at least four reclining regions 401, 402, 403, 404 arranged and / or positioned differently relative to one another on the reclining furniture 200 or the reclining surface 205. The user can individually change, adjust, and / or adapt the individual regions or reclining areas via the control device 120. Figure 6 shows a perspective view of a mattress cover 204 of a reclining furniture 200 according to an exemplary embodiment. Figure 7 shows a highly simplified partial plan view of an outer side of the mattress cover 204 of Figure 6. Figure 8 shows a partially schematic cross-sectional view through a cover material of the mattress cover 204 of Figures 6 and 7.

[0233] Referring to Figure 6, a mattress cover 204 or a mattress protector 204 is shown as an example in a state stretched over a mattress 202 and a base element 100, wherein the cover 204 forms a first lying surface on an upper side 205 and optionally a second lying surface for a user on an opposite underside or floor side 101.

[0234] The mattress cover 204 is formed all the way around from the same cover material 8, with lateral transverse surfaces 6 and longitudinal surfaces 7 also merging, optionally seamlessly, into the top side 6 and bottom side 7. However, in other designs, the surfaces of the cover material 8 can also be separated by seams and, if necessary, a piping tape.

[0235] A circumferential closure 206 in the form of a zipper is sewn into the mattress cover 204 (or mattress protector 204) on the transverse surfaces 6 and longitudinal sides 7 for inserting and removing the mattress 202 and / or the base element 100. In addition, several carrying handles 210 are provided on the lateral longitudinal surfaces 7 for lifting the base element 100 and / or the mattress 202 spanned by the mattress cover 204 (or mattress protector 204), of which only one carrying handle 210 is shown as an example.

[0236] As can be seen in a section X in Figure 6, which represents the entire surface of the mattress cover 204 (or mattress protector 204), and in Figures 7 and 8, the cover material 8 is formed with a spacer knit 10, for example a 3D spacer knit, up to its outer side 11.

[0237] The cover fabric 8 has a honeycomb-like mesh structure with outwardly open recesses 12 arranged in a regular, finely structured pattern. The recesses 12 preferably have a round, rounded, elliptical, and / or oval cross-section, which, in the unstretched state, can be, for example, 2 mm to 4 mm wide and approximately 3 mm to 5 mm long.

[0238] The material webs 13 made of spacer fabric 10 located between the recesses 12 which are offset and regularly arranged relative to one another can be dimensioned at least approximately equally in width.

[0239] The cover material 8 of the cover is in the present case designed as a two- or three-layer spacer knit, with an upper layer 14 forming the outer side 11, an optional middle layer 15 forming the spacer knit 10 and knitted with the upper layer 14, and an inner or lower layer 16 which is knitted with the upper layer 14 and / or the optional middle layer 15.

[0240] The upper layer 14 can comprise a monofilament yarn, such as a smooth monofilament yarn, or a multifilament yarn, such as a textured, twisted multifilament yarn. Similarly, the lower layer 16 can also comprise a monofilament yarn, such as a smooth monofilament yarn, or a multifilament yarn, such as a textured, twisted multifilament yarn. Likewise, the middle layer 15 can be formed at least partially from monofilament yarns or multifilament yarns.

[0241] One or more of the upper layer 14, the middle layer 15, and the lower layer 16 may further contain natural fibers and / or be at least partially formed from natural fibers, as described above. The natural fibers may be, for example, animal hair fibers, wool fibers, cotton fibers, hemp fibers, eucalyptus fibers, bamboo fibers, linen fibers, wood fibers, viscose fibers, flax fibers, silk fibers, plant fibers, or a combination thereof. Such natural fibers may be characterized, for example, by increased sustainability, odor neutrality, skin compatibility, durability, and / or robustness compared to synthetic fibers.

[0242] The upper layer 14 also has a fine-knit structure 17 on the outer side 11, which gives the surface a soft feel.

[0243] In terms of thickness, the upper layer 14 in the advantageous embodiment shown is dimensioned such that it occupies at least 70% to 80% of the total thickness of the cover material 8 in order to utilize the microclimatic advantages of the spacer knit 10 to the greatest extent possible. To enable maximum air circulation and optimal moisture removal to the outer side 11, the honeycomb-like recesses 12 extend essentially over the thickness of the upper layer 14 and the middle layer 15 to adjacent to the lower layer 16, so that the cover material simultaneously exhibits high flexibility and extensibility across its width thanks to the recesses 12. The elasticity in height creates a softness that can be defined by the filler of the middle layer 15, depending on the desired degree of softness.

[0244] It is understood that, depending on the application, the cover fabric 8 can be manufactured using any known spacer knitting process, as well as any known finishing process, such as a washing, bleaching, and shrinking process following the knitting process. Optionally, the mattress cover 204 can be at least partially coated, rubberized, and / or provided with latex to prevent water penetration.

[0245] Figures 9a to 9f each show parts of a mattress 202 of a piece of reclining furniture 200 according to exemplary embodiments. Figure 9a shows a plan view of a first mattress element 2 of a mattress 202 of a piece of reclining furniture 200. The mattress 202 of Figures 9a to 9f can be combined with all of the above aspects of the reclining furniture 200, or individual aspects can be exchanged. Figure 9b schematically shows a cross-section of the first mattress element 2 of Figure 9a, wherein the first mattress element 2 is shown without transverse grooves in Figures 9a and 9b. Figure 9c shows a side view of the first mattress element 2 of Figures 9a and 9b with a plurality of transverse grooves. Figure 9d shows a plan view of a second mattress element 3 according to an embodiment of the invention. Figure 9e shows a cross-section of the second mattress element 3 of Figure 9d without transverse grooves. Figure 9f shows a mattress 202 or a combination mattress 202 of the reclining furniture 200 according to an embodiment of the invention.The mattress 202 of Figure 9f comprises the first mattress element 2 described with reference to Figures 9a to 9c and the second mattress element 3 described with reference to Figures 9d and 9e.

[0246] The first mattress element 2 has a first outer surface 21 and an oppositely arranged first contact surface 22. The first outer surface 21 is designed as a first lying surface 21 for the user. The second mattress element 3 has a second outer surface 31 and an oppositely arranged second contact surface 32. The second outer surface 31 is optionally designed as a second lying surface 31 for the user. The first and second mattress elements 2, 3 are stacked on top of one another in such a way that the first and second contact surfaces 22, 32 are at least partially in contact with one another.

[0247] For ergonomic and comfortable support of the user, the two mattress elements 2, 3 and / or the mattress 202 and / or the reclining furniture 200 each have a plurality of support areas 41, 42, 43, 44, 45. The support areas 41, 42, 43, 44, 45 can include a head support area 41, a neck support area 42, a shoulder support area 43, a lumbar support area 44, and a pelvic support area 45.

[0248] The mattress 202 has a longitudinal direction x (107 in Figures 1a to 3) or longitudinal axis x, which runs parallel to a long side of the mattress 202, a transverse direction y (109 in Figures 1a to 3) or transverse axis y, which runs parallel to a long side of the mattress 202, and a vertical axis z, which runs transversely and / or orthogonally to the longitudinal direction x and the transverse direction y. A length of the mattress 202 of the reclining furniture 200 is measured in the longitudinal direction x, a width of the mattress 202 is measured in the transverse direction y, and a thickness or height of the mattress is measured along the vertical axis z. The length of the mattress 202 can be greater than or equal to the width of the mattress 202. The first mattress element 2 and the second mattress element 3 can have identical or different heights and / or thicknesses. 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 y-direction can run parallel to the transverse axis 109 of the base element 100 and / or the reclining furniture 200.

[0249] Furthermore, the mattress 202 of the reclining furniture 200 has a central transverse axis 5 and / or a central transverse plane 5, which runs parallel to the transverse direction y and is arranged centrally between two ends of the mattress 202 that are opposite one another in the longitudinal direction x. The central transverse axis 5 and / or the central transverse plane 5 separates the first mattress element 2 into a first half 2a and a second half 2b. Likewise, the central transverse plane 5 and / or the central transverse axis 5 separates the second mattress element 3 into a first half 3a and a second half 3b.

[0250] Each of the halves 2a, 2b, 3a, 3b of the first and second mattress elements 2, 3 has the support regions 41, 42, 43, 44, 45. The support regions 41, 42, 43, 44, 45 are arranged mirror-symmetrically to the central transverse axis 5. The individual support regions 41, 42, 43, 44, 45 can differ from one another at least in part with regard to a degree of hardness, a hardness, a compression strength and / or an elasticity. For example, the support regions 41, 42, 43, 44, 45 can have at least partially different profiles, profilings and / or structurings, for example in the form of transverse grooves 51, 52, 53, 54 formed in the respective support regions 41, 42, 43, 44, 45. The transverse grooves 51, 52, 53, 54 can be formed in the first and / or second outer surface 21, 31 and extend over the entire width of the mattress 202 in the transverse direction y.In order to adapt the hardness of the individual support areas 41, 42, 43, 44, 45, profiles and / or the transverse grooves 51, 52, 53, 54 in the respective support areas 41, 42, 43, 44, 45 can differ from one another with regard to their cross-section, their geometry, their shape, their number, their depth measured along the vertical axis z and / or their thickness or size measured along the longitudinal direction x.

[0251] As can be seen in Figure 9c, the first mattress element 2 has a single first transverse groove 51 in each of the two halves 2a, 2b, which separates the head support area 41 from the neck support area 42. The first transverse groove 51 has a T-shaped cross-section.

[0252] Furthermore, the first mattress element 2 has a total of five second transverse grooves 52 in the shoulder support region 43 in each of the two halves 2a, 2b, each of which has a round, oval, elliptical, and / or drop-shaped cross-section. The geometry, width, dimensions, size, thickness, and / or diameter of the five second transverse grooves 52 in the shoulder support regions 43 of the two halves 2a, 2b of the first mattress element 2 are identical. The neck support regions 42 of the first mattress element 2 are separated by one of the second transverse grooves 52 from the shoulder support regions 43 adjacent to the neck support regions 42. Likewise, the lumbar support regions 44 adjacent to the shoulder support regions 43 in the direction of the central transverse axis 5 are separated from the respective shoulder support region 43 by one of the second transverse grooves 52. Furthermore, the lordosis support areas 44 are each separated from the adjacent pelvic support areas 45 by a third transverse groove 53.In the two pelvic support areas 45 adjacent to each other along the central transverse axis 5, a total of three third transverse grooves 53 are formed, each having a T-shaped and / or triangular cross-section. The three third transverse grooves 53 have identical geometries, widths, dimensions, sizes, thicknesses, and / or diameters. The middle of the three third transverse grooves 53 can extend in the central transverse plane 5 and define a boundary between the first half 2a and the second half 2b.

[0253] As shown in Figure 9f, at least one further transverse groove 54 can be formed in each of the lumbar support regions 44, which can, for example, have a round and / or oval cross-section. As can be seen in Figure 9f, the first mattress element 2 has no profile, no profiling and / or no structuring on its first contact surface 22. In other words, the first contact surface 22 is completely flat. Optionally, however, a profile can also be formed on the first contact surface 22, at least in a partial area. Any cross-sectional profiles for transverse grooves are conceivable here, such as round, oval, elliptical, triangular, square, polygonal, trapezoidal or the like, as explained above and below.

[0254] As can be seen in Figure 9f, the second mattress element 3 has a single first transverse groove 61 in each of the two halves 3a, 3b, which separates the head support area 41 from the neck support area 42. The first transverse groove 61 is configured analogously to the first transverse groove 51 of the first mattress element 2 and has a T-shaped cross-section. Furthermore, the second mattress element 3 has a total of five second transverse grooves 62 in the shoulder support area 43 in each of the two halves 3a, 3b, each of which has a round, oval, elliptical, and / or drop-shaped cross-section. The second transverse grooves 62 of the second mattress element 3 are designed analogously to the second transverse grooves 52 of the first mattress element 2, but a width, dimension, size, thickness and / or a diameter of the five second transverse grooves 62 in the shoulder support areas 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 areas 42 of the second mattress element 3 are separated from the shoulder support areas 43 adjacent to the neck support areas 42 by one of the second transverse grooves 62. Likewise, the lordosis support areas 44 adjacent to the shoulder support areas 43 in the direction of the central transverse axis 5 are separated from the respective shoulder support area 43 by one of the second transverse grooves 62. Furthermore, the lordosis support areas 44 are each separated from the adjacent pelvic support areas 45 by a third transverse groove 63. In the two pelvic support areas 45 adjacent to one another along the central transverse axis 5, a total of three third transverse grooves 63 are formed, which are designed analogously to the transverse grooves 53 of the first mattress element 2 and each have a T-shaped and / or triangular cross-section. The three third transverse grooves 63 have identical geometries, widths, dimensions, sizes, thicknesses, and / or diameters.The middle of the three third transverse grooves 63 can extend in the central transverse plane 5 and define a boundary between the first half 3a and the second half 3b. Furthermore, analogous to the further transverse groove 54 of the first mattress element 2, at least one further transverse groove 64 can be formed in each of the lumbar support areas 44 of the second mattress element 3, which can, for example, have a round and / or oval cross-section.

[0255] 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 formed 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 designed to be completely mirror-symmetrical to the central transverse axis 5 or central transverse plane 5.

[0256] As shown in Figure 9f, the second mattress element 3 has a profile 33 on its second contact surface 32, which has a plurality of transverse grooves 34. The transverse grooves 34 are shown with a rectangular cross-section as an example. Any other cross-sections are conceivable.

[0257] The profile 33 can also be wave-shaped with multiple wave crests and troughs. Alternatively or additionally, the profile 33 or another profile can be incorporated into the contact surface 22 of the first mattress element 2. Profiles and / or transverse grooves, which can at least partially interlock, can also be incorporated into both contact surfaces.

[0258] Exemplary transverse 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.

[0259] Figures 10 to 13 each show exemplary transverse grooves of a mattress 202 of a piece of reclining furniture 200 according to an exemplary embodiment. In particular, longitudinal sections through the respective mattress 202 are shown.

[0260] The mattress 202 of Figure 10 is a total of three parts and has three mattress elements 2, 3, 3'. The mattresses 202 of Figures 11 to 13, in contrast, have only two mattress elements 2, 3. However, any number of mattress elements can be provided.

[0261] The transverse grooves and / or profiles shown in Figures 10 to 13 are arranged merely schematically and exemplarily on the contact or outer surfaces of the mattress elements 2, 3, 3' shown there. However, the transverse grooves and / or profiles can also be arranged on any other surfaces of the mattress 202.

[0262] In the example in Figure 10, the first mattress element 2 has no profile or transverse grooves. The second mattress element 3 has trapezoidal transverse grooves 500 on the contact surface 32 and rectangular transverse grooves 600 on a side or surface opposite this contact surface 32, which are recessed and / or inserted into the second mattress element 3 at a distance from this surface. Another mattress element 3' without a profile forms the further outer surface of the mattress 202.

[0263] In the example of Figure 11, the first mattress element 2 has 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 surface 31, and the contact surface 32 is profileless.

[0264] In Figure 12, the first mattress element 2 has bean-shaped transverse grooves 500, which are introduced into the first mattress element 2 via incisions 501 from the first contact surface 21, such that the transverse grooves 500 are arranged 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. Similar transverse grooves 600 with incisions 601 are introduced into the second mattress element 3 via the second contact surface 32. The transverse grooves 600 are boomerang-shaped, coat hanger-shaped and / or triangular in shape. Furthermore, further transverse grooves 603 with a round cross-section are introduced into the second mattress element 3. The second outer surface 31 of the second mattress element 3 has no profile.

[0265] In the example shown in Figure 13, the first mattress element 2 and the second mattress element 3 have corresponding profiles and / or transverse grooves 500, 600 on their contact surfaces 22, 32, which at least partially interlock in a tooth-like manner. The outer surfaces 21, 31 of the two mattress elements 2, 3 are profileless.

[0266] Figures 14-17 show various views of the cover layer 101b. For example, Figures 14 and 16 show a perspective view and a plan view of the drive side 152 of the cover layer 101b. Figures 15 and 17, in turn, show a perspective view and a plan view of the mattress side 153 of the cover layer 101b. The drive side 152 of the cover layer 101b is the side that faces the adjustment device 300 when the base element 100 is in the assembled state. The mattress side 153 of the cover layer 101b, on the other hand, is the side that, when the base element 100 is in the assembled state, is intended for a mattress 202 to be placed on or is placed on. It faces away from the adjustment device 300.

[0267] As can be seen from Figures 14-17, the cover layer 101 b has different areas in the longitudinal direction X, specifically the head pivot area 140, the foot pivot area

[0268] 141 and the drive region 142. The drive region 142 is located in the longitudinal direction X in the middle between the head pivoting region 140 and the foot pivoting region 141 and is connected to the head pivoting region 140 and the foot pivoting region 141. As can be seen in particular from Figures 16 and 17, the drive region 142 has an extension in the transverse direction Y that is smaller than the extension in the transverse direction Y of the head pivoting region 140 and also of the foot pivoting region 141. Furthermore, it can be seen that the drive region 142 has a constant extension in the transverse direction Y over its entire extension in the longitudinal direction X.

[0269] This does not apply to the head pivoting area 140 and the foot pivoting area 141. In particular, the head pivoting area 140 has a first rail area 143 and a first filling area 160, each of which has a different extension in the transverse direction Y. Specifically, the extension in the transverse direction Y of the first filling area 160 is greater than that of the first rail area 143. The first rail area 143 is the area of ​​the head pivoting area 140 that is connected to the drive area

[0270] 142 or directly adjacent to it. Analogously, the foot pivot area 141 has a second rail area 144 and a second filling area 161, each of which has a different extent in the transverse direction Y. Specifically, the extent in the transverse direction Y of the second filling area 161 is greater than the second rail area 144. The second rail area 144 is that area of ​​the foot pivot area 141 that is connected to the drive area 142 or directly adjacent to it. Furthermore, the extent in the transverse direction Y of the aforementioned rail areas 143, 144 and filling areas 160, 166 is constant along the longitudinal direction X. The individual areas are therefore connected in a step-like manner. Between the individual areas there are therefore step-shaped recesses and projections in the transverse direction Y. These are always located on both end faces of the respective areas that are spaced apart in the transverse direction Y.In other words, a partial region that has a smaller extension in the transverse direction Y is set back inwardly relative to an adjacent partial region on both outer sides spaced apart from each other in the transverse direction Y. Overall, this results in an hourglass-shaped structure for the cover layer 101b, with the drive region 142 forming the narrowest point or section of the cover layer 101b in the transverse direction Y.

[0271] The cover layer 101b preferably has a uniform base body 145. For example, the base body 145 is formed from a foam material. The base body 145 of the cover layer 101b has a thickness parallel to the vertical axis Z that corresponds to the thickness of the frame element 101a parallel to the vertical axis Z. This applies to all areas of the cover layer 101b with the exception of a small section of the drive area 142. In the drive area 142, the cover layer 101b has a channel-shaped recess on the drive side 152, which is designed as a shaft tunnel 146. In the area of ​​the shaft tunnel 146, the cover layer 101b correspondingly has a reduced thickness parallel to the vertical axis Z. The shaft tunnel 146 is particularly designed to accommodate at least one or all of the shafts 135 of the adjusting device 300. The shaft tunnel 146 extends parallel to the transverse direction Y through or over the entire cover layer 101b.

[0272] Through the operation of the adjustment device 300, the head pivoting area 140 and the foot pivoting area 141 of the cover layer 101b are moved, pivoted, or displaced relative to the drive area 142. To enable this movement continuously without damaging the cover layer 101b, the cover layer 101b has a pivoting groove 147, 148 at the boundary between the head pivoting area 140 and the drive area 142 and at the boundary between the foot pivoting area 141 and the drive area 142. The first pivoting groove 147 is arranged between the head pivoting area 140 and the drive area 142. The second pivoting groove 148 is arranged between the foot pivoting area 141 and the drive area 142. The pivoting grooves 147, 148 are located on the drive side 152 of the cover layer 101b.

[0273] The pivot grooves 147, 148 are preferably identical in design. For example, they have a first incision 149 that extends parallel to the transverse direction Y across the entire cover layer 101b and runs parallel to the vertical axis Z. In other words, the pivot grooves 147, 148 on the drive side 152 comprise a first incision 149 into the thickness or into the base body 145 of the cover layer 101b, wherein the cutting direction of the incision 149 runs parallel to the vertical axis Z. Additionally, it can be provided that the pivot grooves 147, 148 comprise a further, second incision 150 that, starting from the first incision 149, runs at an angle, for example, an angle of 45°, into the base body 145 of the cover layer 101b.Furthermore, it can additionally be provided that the pivot grooves 147, 148 comprise a further, third incision 151, which also extends from the first incision 149 at an angle, for example, an angle of 45°, into the base body 145 of the cover layer 101b. Preferably, the pivot grooves 147, 148 comprise all three mentioned incisions 149, 150, 151. The two angled incisions 150, 151 are arranged on different sides in the longitudinal direction X of the first incision 159. Overall, all incisions 149, 150, 151 extend over the entire extent of the cover layer 101 b in the transverse direction Y. None of the incisions 149, 150, 151 of the pivot grooves 147, 148 completely penetrates the cover layer 101 b or the thickness or the base body 145 of the cover layer 101 b.

[0274] As can be seen in particular from Figures 16 and 17, the drive region 142 of the cover layer 101b is arranged laterally offset in the transverse direction Y, so that the cover layer 101b is designed asymmetrically in the transverse direction Y. In this way, different amounts of space are available between the drive region 142 of the cover layer 101b and the frame element 101a in the transverse direction Y on different sides of the drive region 142. In this way, an asymmetrically designed adjustment device 300 can also be advantageously accommodated in a receiving space 130 (see Figure 22) between the cover layer 101b and the frame element 101a.

[0275] Figure 18 shows a perspective top view of the frame element 101a. As can be seen in particular from a comparison of Figures 16 and 17 with Figure 18, the cover layer 101b is formed as a section from the frame element 101a, in particular as a section from the compartment 102 of the frame element 101a. It is preferably provided that before the cover layer 101b is cut out of the compartment 102 of the frame element 101a, the pivot grooves 147, 148 are introduced into the entirety of the frame element 101a and the cover layer 101b. In this way, it is ensured that the pivot grooves 147, 148 extend continuously through both the frame element 101a and the cover layer 101b and that the respective portions of the pivot grooves 147, 148 continue into one another.The same can preferably also apply to the corrugated tunnel 146, which can also be provided in the frame element 101a in addition to the cover layer 101b, whereby this mainly relates to simplifying the production of the base element 100 overall. To further simplify production, it can be provided that the frame element 101a is cut open radially outwards from the compartment 102. This allows the frame element 101a to be folded outwards, which, for example, facilitates removal of the cover layer 101b from the compartment 102. However, to ensure structural cohesion of the frame element 101a, it can be provided that a plug connection 154 is provided at the point at which the frame element 101a is cut open outwards. The plug connection.

[0276] 154 generally forms a positive connection between the separated portions of the frame element 101a, so that they can be fastened to one another and the frame element 101a can thus be closed. For this purpose, the frame element 101a can, for example, be cut open outwards in such a way that a cylindrical structure is formed on one side and a corresponding hollow cylindrical structure is formed in the frame element 101a on the other side. The cylindrical structure is designed such that it can be inserted into the hollow cylindrical structure. In this way, the frame element 101a can be fastened to itself and form a closed structure that completely surrounds the compartment 102.

[0277] The compartment 102 completely penetrates the frame element 101a. However, so that the adjustment device 300 can be securely stored in the frame element 101a, the compartment 102 must be closed on the first side 118 of the frame element 101a, i.e., on the side of the frame element 101a facing a floor. For this reason, a base 155 is provided on the first side 118 of the frame element 101a. The base 155 is, for example, a textile, such as a nonwoven fabric. It is preferably attached, for example, glued, to the first side 118 of the frame element 101a. To ensure that the mobility of the base element 100 is not restricted by the base 155, a notch 156 is provided in the base 155. The incision 156 runs parallel to the transverse direction Y and in particular also parallel to the pivot grooves 147, 148. Furthermore, the incision 156 is arranged between the pivot grooves 147, 148.For example, the notch 156 can be arranged in the longitudinal direction X at the level of the first pivot groove 147. As indicated by the dashed notch 156 in Figure 18, the notch 156 can also alternatively be arranged centrally or in the middle between the two pivot grooves 147, 148. The notch 156 preferably separates the base 155 into two parts, which are arranged consecutively along the longitudinal direction X. A view of the base.

[0278] 155 or onto the first side 118 or the bottom side 101 of the frame element 101a or the base element 100 is shown in Figure 23. Figure 19 shows a frame element 101a with an adjustment device 300 arranged in the compartment 102. As can be seen from the detailed view in Figure 20, the adjustment device 300 has a power supply 157, for example an external power supply via a power cable. The power supply 157 is guided in particular through one of the pivot grooves, specifically the first pivot groove 147, into the interior of the frame element 101a and to the adjustment device 300. The pivot grooves 147, 148, in particular the first pivot groove 147, can therefore also be designed as cable ducts or cable channels in addition to their function of ensuring the mobility of the base element 100. In addition, Figure 20 also shows a pull actuator 159, which for example has a ring orPull ring and a pulling means, for example a cord or a string. In particular, the detailed view according to Figure 21 shows that the pull actuator 159 extends from the outside of the frame element 101a or the base element 100 into the compartment 102 and in particular to the adjusting device 300 or the drives 108, 108'. In particular, the pull actuator 159 is connected to an emergency release 158 of the adjusting device 300 or the drives 108, 108'. The emergency release 158 is designed such that the adjusting device 300 can be moved or adjusted manually after the emergency release 158 has been released or activated.For example, if the power supply to the adjustment device 300 is interrupted, an operator can activate the emergency release 158 via the pull actuator 159 and then manually move the adjustment device 300 into a neutral starting position, for example, a position in which the rails 140, 140' are aligned parallel to the longitudinal direction X. This ensures that a mattress 202 deformed by the adjustment device 300 can be brought into a neutral position suitable for sleeping even if the power supply is interrupted.

[0279] Figure 22 shows the entire base element 100, but without a cover. Figure 22 therefore shows the base 155, the frame element 101a, the adjustment device 300, and the cover layer 101b. In particular, Figure 22 shows that the cover layer 101b is shaped such that it completely fills the compartment 102 of the frame element 101a except for a receiving space 130 for the adjustment device 300. In particular, the cover layer 101b fills the compartment 102 on the second side 116 of the frame element 101a flush with the frame element 101a. The base element 100 therefore provides a flat support surface for the mattress 202, so that the base element 100 is not perceived by an operator lying on the mattress 202 except for the possible deformation of the mattress 202 by the adjustment device 300.

[0280] Figures 24 and 25 show the adjustment device 300 in a side view. In particular, Figures 24 and 25 show the reduction in the overall length of the adjustment device 300 and thus of the base element 100. Figure 24 shows the adjustment device 300 in a lying position, i.e., a position in which the base element 100 can be used as intended by a user. Figure 25, in contrast, shows the adjustment device 300 in a transport position, into which it can be brought by pivoting its parts.

[0281] It has already been explained that the rail elements 105a, 105c, together with their longitudinal support struts 302, can be pivoted about the rail element 105b by the adjustment device 300. This adjustment movement can also be used to reduce the dimensions of the adjustment device 300.

[0282] A further, significant reduction in size can be achieved if at least the longitudinal support struts 302 on one side, preferably the side of the head pivoting area 140 or the side having the longer longitudinal support struts 302, are designed to be shortenable. For this purpose, the longitudinal support struts 302 can be divided into two parts 302a, 302b, which are pivotally attached to one another or connected to one another via a hinge 304. In particular, the hinge 304 is designed such that the two parts 302a, 302b of the longitudinal support struts 302 can be pivoted such that they can be moved from a position arranged one behind the other (Figure 24), in which the end faces of the longitudinal support struts 302 are opposite one another, to a position arranged side by side (Figure 25), in which the long sides of the longitudinal support struts 302 are opposite one another.In other words, one part 302b of the longitudinal support struts 302 can be folded over such that it rests against the other part 302a of the longitudinal support struts 302. This allows the overall length of the longitudinal support struts 302 to be significantly reduced, thereby facilitating handling and, in particular, shipping of the base element 100 or the reclining furniture 200.

[0283] Figure 26 shows an embodiment of the reclining furniture 200 with a reclining furniture cover 204 surrounding the base element 100 and the mattress 202. In particular, the reclining furniture cover 204 is the only cover of the reclining furniture 200. This means that neither the base element 100 nor the mattress 202 has a separate cover. The mattress 202 can therefore be a mattress core without a cover. The base element 100 and the mattress 202 or the mattress core are placed or stacked on top of one another, with the mattress 202 or the mattress core lying or being arranged on the base element 100. Together, they are surrounded by the reclining furniture cover 204.

[0284] The reclining furniture cover 204 preferably has an outer layer made of the cover material s described herein, i.e., the spacer knit. The cover material s completely surrounds the reclining furniture 200 on the outside. In addition, the reclining furniture cover 204 can comprise a cushioning layer 352 and / or a base 351. The cushioning layer 352 and / or the base 351 are arranged, in particular, exclusively in the lower half of the reclining furniture cover 204. They extend not only on the underside, but are also guided at least partially upwards in the direction of the vertical axis Z at the front ends of the reclining furniture cover 204. They therefore form an upwardly open trough in which the base element 100 can be received. As shown in the enlarged detail in Figure 26, the cover material s, the cushioning layer 352, and the base 351 follow one another from the outside to the inside on the underside of the reclining furniture cover 204.The base 351 can be in direct contact with the base element 100. In particular, the cushioning layer 352 and the base 351 extend at the end faces in the direction of the vertical axis Z as far as the base element 100.

[0285] The mattress 202, on the other hand, is not surrounded by the upholstery layer 352 and the base 351 either on the front sides or on the top side of the recliner 200. Here, however, only the layer of the cover material 8 is located in the area of ​​the mattress 202, whereby the feel of the mattress 202 and the cover material 8 for a user lying on the recliner is not changed by the upholstery layer 352 or the base 351.

[0286] Additionally, it should be noted that "comprising" and "having" do not exclude other elements, and "a" or "an" does not exclude a plurality. Furthermore, it should be noted that features described with reference to one of the above embodiments can also be used in combination with other features of other embodiments described above. Reference symbols in the claims are not to be considered as limitations.
