Description

[0001] The invention relates to a fitting for changing the usage position of a seating and / or reclining furniture and to a seating and / or reclining furniture with this fitting. State of the art

[0002] Prior art includes, for example, DE 20 2005 016 129 U1, a seating and / or reclining furniture which has a fixed backrest. Additionally, a second backrest, which can be positioned and attached in a movable manner, is provided, with both backrests being connected to each other via fittings. The second backrest can be moved in its position by means of a lifting or swiveling device.

[0003] Furthermore, DE 20 2007 013 545 U1 discloses a seating and / or reclining furniture with an adjustable backrest, which is designed in two parts. By pivoting the first backrest section accordingly, the seating area can be reduced and made smaller. For this purpose, DE 20 2007 013 545 U1 describes a fitting system in which the front, inner fitting element is shorter than the rear, outer fitting element in order to enable the corresponding pivoting of the first backrest section.

[0004] Both of these known seating and / or reclining furniture pieces share the characteristic that the backrest position can only be adjusted with difficulty and inconvenience. Furthermore, only the position of the backrest can be changed. This is disadvantageous for users, as it prevents them from assuming a comfortable sitting position with their legs raised, and adjusting the backrest proves to be very cumbersome. Both of these pieces require a separate stool or footrest. If the backrest is to be adjusted, it is still necessary to stand up and manually adjust the position. Consequently, the operation and handling of these pieces of seating and / or reclining furniture is inconvenient and complicated.

[0005] DE 20 2017 104 400 U1 discloses a piece of seating and / or reclining furniture, in particular upholstered furniture, consisting of a load-bearing substructure and at least one seating or reclining element. This element comprises a seat section, a foot section, and a multi-section backrest. The backrest consists of a lower and an upper backrest section, which are movably connected to each other via a locking fitting. The lower backrest section is connected to a support, which in turn is attached to the substructure, via rod- or strip-shaped fitting elements. In every operating position, certain bearing points of the fitting elements are at the same height. When adjusted to a different operating position, the inclination of the backrest section and / or the position of the foot section changes. The backrest and foot section are coupled via a force transmission linkage, and the upper backrest section has locking elements for modular adjustment of its inclination.

[0006] AT 008 579 U1 discloses a fitting for pivoting the upper part of a split backrest of seating furniture. For pivoting, two downwardly pivotable arms are arranged on the upper part, at the lower ends of which a link is articulated, each link being pivotally mounted on a mounting plate in the furniture frame. Task

[0007] Therefore, the present invention aims to provide a seating and / or reclining furniture and a fitting for it, which enables an extended depth adjustment range of the seating and / or reclining surface and which can be implemented easily and conveniently. Furthermore, it is an object of the present invention to provide a fitting which, in its installed state, creates a more comfortable seating position in a seating and / or reclining furniture than is known from the prior art. Finally, it is an object of the present invention to provide a fitting with which the backrest of a seating and / or reclining furniture can be moved easily and with minimal effort from a low reclining position to a high reclining position. Solution

[0008] This problem is solved according to the features of claim 1 and claims 9 and 10.

[0009] A key aspect of the invention is that the fitting for changing the operating position of a seat and / or reclining furniture has at least one locking fitting carrier for receiving at least two rod- and / or strip-shaped fitting elements, wherein the rod- and / or strip-shaped fitting elements are articulated on the one hand via an upper bearing on the locking fitting carrier and wherein the rod- and / or strip-shaped fitting elements can be articulated on the other hand via a lower bearing on a carrier, wherein at least one fitting element has at least one extension section projecting upwards beyond the locking fitting carrier.

[0010] According to the invention, the first usage position is, for example, a sitting position with a reduced seat depth. Furthermore, the second, additional usage position is advantageously understood to be a comfortable sitting and / or reclining position with an increased seat depth.

[0011] The fitting elements, together with the locking fitting carrier and the upper bearings, advantageously form the lower backrest section of the finished seating and / or reclining furniture. Furthermore, the fitting elements, together with the locking fitting carrier and the upper bearings, form a lower fitting section to which another, upper fitting section can be attached via the extension.

[0012] The fitting design described here has proven advantageous because the extension section projecting upwards beyond the latching bracket provides an additional coupling element to which further components of the fitting can be attached. The extension section is therefore designed as a lever and functions as a lever. This extension section is advantageous because it allows for the provision of additional functions.

[0013] Further advantageous embodiments are described in the dependent claims.

[0014] In a further advantageous embodiment, the rear, outer fitting element has an extension section that extends beyond the upper bearing and is pivotable about it. The design of this extension section on the rear fitting element creates a particularly space-saving design in the finished seating and / or reclining furniture. Furthermore, the extension section makes the rear, outer fitting element longer at the top than the inner, front fitting element, thus increasing the leverage effect when the locking fitting carrier is subjected to an external force.

[0015] In a further advantageous embodiment, the extension section has a pivot bearing at its free end, to which at least a first section of an upper fitting part is pivotably connected. Advantageously, the fitting described here is formed from at least one lower fitting part and an upper fitting part pivotably coupled thereto.

[0016] In the simplest case, the upper fitting part can be designed in the form of rods and / or strips, as already described for the fitting elements of the lower fitting part.

[0017] In the simplest case, the upper fitting is multi-part and, in addition to the first section, has a second section which is operatively connected to the first section. In the simplest case, the two sections are coupled to each other via a common pivot bearing.

[0018] In a further advantageous embodiment, the second section of the upper fitting part is additionally arranged via a further spacer bearing on a support and pivotable relative to it, wherein the support is essentially vertically oriented and is firmly connected to the latching fitting support.

[0019] The arrangement of the second section with its free end at another spacer bearing is advantageous because it allows the second section to pivot only about the spacer bearing. The support itself, which is essentially vertically oriented upwards, has the spacer bearing at its upper free end and is rigidly connected to the latching bracket at its lower end. The upper end of the support thus serves as a holding surface for the second section, so that when force is applied, it is deflected about the pivot axis of the spacer bearing.

[0020] The first section of the upper fitting part is advantageously hinged to a side surface of the second section, preferably via a further spacer bearing.

[0021] A spacer bearing is advantageously understood to be a bearing that forms a pivot axis offset from the corresponding component. Therefore, the pivot axis of the first section of the upper fitting is advantageously offset below the second section. The pivot bearing of the second section, via which the second section is hinged to the main vertically oriented support, is offset from the support and positioned above it. This has proven advantageously to allow for particularly effortless and simple deflection and pivoting of the two sections relative to each other.

[0022] Advantageously, in a first operating position, the upper fitting part is designed to be tilted. This tilting is advantageously achieved by a folding-swivel mechanism. At least the second section is essentially horizontal and / or inclined downwards towards the locking fitting carrier. Simultaneously, the first section, which is pivotally hinged to the extension section of the rear fitting element, is also arranged in an inclined, folded position.

[0023] If the locking mechanism carrier is now subjected to an external force, for example, a compressive force, this force moves the locking mechanism carrier out of its folded-in initial operating position. The locking mechanism carrier pivots via the upper and lower bearings of the fitting elements. At the same time, the extension section of the rear, outer fitting element is also deflected from its original initial operating position and stands upright. This standing upright movement deflects the first section of the upper fitting part accordingly. This deflection, in turn, applies the transmitted force to the second section via the corresponding spacer bearing, which is advantageously introduced by force transmission. This force transmission to the spacer bearing deflects the second section of the upper fitting part from its horizontal and / or downward-tilted position and also stands upright.Thus, for the first time, it is possible that the previously folded sections of the upper fitting part can be swung out and opened simply by applying a force to the locking fitting carrier.

[0024] Naturally, this process can also be reversed. This can be done manually, for example, or advantageously by coupling the fitting described here with a power transmission linkage for pivoting a foot section of a seat and / or reclining furniture, wherein at least one fitting element has a further downward-facing extension section that extends downwards beyond at least one lower bearing. The power transmission linkage is used to pivot a foot section of a seat and / or reclining furniture from a folded-in position to an unfolded position.In the extended position of the footrest, the user can comfortably rest their feet or lower legs on the footrest, which pivots out from the base of the seat and / or reclining furniture. This, combined with the increased seat depth and the significantly raised, rearward-tilting backrest, allows for a particularly comfortable posture. This combination of changing the backrest angle and pivoting the footrest is achieved via the power transmission linkage. The fitting described here and the corresponding footrest are advantageously coupled via this linkage. Therefore, a change in the fitting's position simultaneously pivots the power transmission linkage and, consequently, the footrest.

[0025] To make the sitting and / or reclining position even more individual and flexible, the present invention describes for the first time the combination of the force transmission linkage with an individually adjustable fitting, which later becomes part of the backrest of a seat and / or reclining piece of furniture. This makes it particularly easy to return the pivoted fitting from its second operating position to its folded first operating position by having the user exert a force on the footrest, which is transmitted via the force transmission linkage to the fitting described here for the first time.Due to the particularly advantageous design of the pivot bearings of the individual components of the fitting in relation to each other, even small forces applied to the foot section are sufficient to move the fitting, which later forms the backrest of a seat and / or reclining furniture, from the unfolded second operating position back into the folded first operating position.

[0026] It is also advantageous if the extension section is at least partially curved. This partial curvature allows the extension section to be guided along a circular path, at least partially, when pivoting and simultaneously straightening, thereby further increasing and improving the leverage effect on the upper fitting.

[0027] In a further advantageous embodiment, it has proven beneficial if the locking fitting carrier has at least one stop element with which the extension section forms a common contact surface in a first operating position. This is advantageous because the stop element thus prevents the extension section from over-rotating and, for example, being guided against the front, inner fitting element and blocking it. At the same time, the stop element also defines the end position of the first operating position. The extension section can be pivoted up to the stop element so that it forms a contact surface. Further pivoting is then no longer possible. This serves to protect the user by preventing pinching.

[0028] Furthermore, the present invention relates to a method for actuating an additional adjustment of a fitting, which comprises at least the following steps: a. Force application via the locking fitting carrier of the fitting in a first operating position, b. This results in the deflection of the two fitting elements of the lower backrest section backwards over the bearings, with simultaneous pivoting of the extension section and the first section articulated to it. c. Simultaneous movement of the first section against the second section, which thereby experiences a force being applied and is deflected and set up from its first operating position.

[0029] This is of course not to be understood as a limitation, so it is also conceivable that further additional, optional steps could be carried out. For example, it is conceivable that when the fitting described here is coupled with a force transmission linkage and a corresponding foot, the fitting could also be returned from the second operating position back to the first operating position.

[0030] The method described here for the first time has proven particularly advantageous, as it is more energy-efficient and easier to implement than any method previously known in the prior art. Furthermore, it eliminates the need for any electrical components, such as drive units. Of course, the use of such drive units, such as electric motors, is not entirely excluded.

[0031] Finally, the present invention also relates to a seating and / or reclining furniture with at least one fitting and / or with which the method described herein can be carried out accordingly.

[0032] The term "seating and / or reclining furniture" as used in the present invention can refer to single-seat or multi-seat seating and / or reclining furniture in upholstered or unupholstered versions. In particular, in upholstered versions, the seating and / or reclining furniture described here can be fully upholstered, for example, with an upholstered substructure, upholstered elements attached to the seat, footrest, and backrest, or other connecting parts that are movable or fixed. In an unupholstered version, for example, backrests or armrests can be made of wood or the like, and / or the substructure can also be at least partially unupholstered.

[0033] The rod- and / or strip-shaped fitting elements, which are pivotally hinged to the locking fitting carrier on one side and to the support on the other, advantageously form the first, lower backrest section of the seating and / or reclining furniture. It is particularly advantageous to use two fittings described here per seating unit of the seating and / or reclining furniture. These two fittings are particularly advantageously connected to each other via the locking fitting carrier, which can, for example, be designed as a plate-like crossbar. Surprisingly, it has been found that the fitting described here exhibits particularly good force transmission, and a previously folded backrest of a seating and / or reclining furniture can be unfolded with only minimal force.

[0034] When the backrest of a chair or lounger is folded down, the furniture itself can be sat on comfortably, albeit with a reduced seat depth. However, if, for example, one wants to watch television or read a book, the reclining position is advantageous. The reclining position is understood as a second operating position, whereby, by applying slight pressure to the locking mechanism, the previously folded backrest of the chair or lounger unfolds and extends upwards. This is advantageously achieved for the first time by the fitting described here. Thus, the back support surface for the user sitting on the chair or lounger is effectively doubled. The user can therefore comfortably lean not only their lower back, but their entire back and, ideally, their head against the unfolded backrest. This is the second operating position.If a corresponding power transmission linkage is provided, the footrest is also extended in the second operating position, allowing the user to comfortably rest their feet or legs. It is not necessary for the footrest to be pivotable within a substructure. The footrest can simply be pivotable relative to the substructure.

[0035] To return to a normal sitting position, the user applies pressure to the footrest, pivoting it downwards relative to the base. The applied force is then transmitted via the force transmission linkage towards the backrest, thus moving the mechanism described here from its extended second operating position back to its folded-in position. This transition from the second to the first operating position also reduces the seat depth, as the mechanism pivots forwards and downwards towards the seat surface.

[0036] Furthermore, it has proven advantageous if the locking mechanism carrier has an orientation other than horizontal in the second operating position. A particularly advantageous position is one in which the locking mechanism carrier is angled downwards and backwards. This provides an additional comfortable seating position for the user when the fitting is located in the backrest of a seat and / or reclining furniture.

[0037] Furthermore, it has also proven advantageous for force transmission if the two fitting elements that form the lower part of the backrest in a seat and / or reclining furniture are no longer parallel to each other in the second operating position. This decoupling of the two fitting elements from each other is achieved by the downward and backward tilt of the locking fitting carrier. This decoupling also ensures simpler and better force transmission to the upper sections of the fitting element.

[0038] In a further advantageous embodiment, the force transmission linkage is designed as a coupling element between the first backrest section and the foot section, wherein the force transmission linkage transmits a deflection of the first backrest section to the foot section and vice versa. The force transmission linkage is therefore suitable for transmitting forces acting from the foot section to the first backrest section and / or from the first backrest section to the foot section, so that both parts can be changed in their position and / or tilt and / or pivot position essentially simultaneously. Consequently, operation and handling are simplified for the user, since applying force only to the first backrest section and / or to the foot section is sufficient to pivot the foot section and / or the backrest section accordingly, and vice versa.

[0039] In a particularly preferred embodiment, the locking mechanism carrier can be subjected to a compressive force, for example, by the user's back. This compressive force is transmitted to the footrest via the force transmission linkage. The footrest is then extended from its initial, folded-down position. By simultaneously pivoting back and raising the entire backrest and unfolding the footrest, the seating area is enlarged. The user can then assume the comfortable second position, the reclining position.

[0040] If the user wishes to return to the original sitting position, pressure is applied to the footrest, for example, via the feet or lower legs. By essentially pushing the footrest downwards, this force is transferred via the force transmission linkage to the first part of the backrest, causing it to pivot forward again and extend at least partially over the seat. This reduces the seat depth.

[0041] In a further advantageous embodiment, the front or inner fitting element has an extension that extends beyond the lower bearing into the substructure. This extension is advantageously part of the force transmission linkage and thus enables the coupling between the foot section and backrest already described in detail above. The extension is designed as a lever arm. It allows for easy pivoting by utilizing leverage.

[0042] It has proven particularly advantageous to design the extension in a Z-shape and to pivot its free end to a crossbeam via a pivot axis. The one-piece construction of the front or inner fitting element with its extension provides exceptionally high stability and a particularly effective lever arm, so that when force is applied to the locking fitting carrier, advantageously in a horizontal rearward direction, the Z-shaped extension within the substructure acts as a lever arm. By coupling the free end of the extension to the crossbeam, the crossbeam is also moved when the first backrest section is deflected from its initial operating position, advantageously forward toward the foot section.

[0043] Alternatively, the extension can be designed straight, omitting the Z-shaped bend in the longitudinal extent of the front fitting element described above. This straight design also results in an extended lever arm. The rear fitting element is then hinged to the support at its end, while the front fitting element is also hinged to the support, with its end extending further downwards towards the base of the substructure. For particularly effective force transmission, the length ratio is less than 1:1, preferably 1:2, 1:2.5, 1:3, 1:3.5, or 1:4, where this always refers to the ratio of the longitudinal extent of the extension to the longitudinal extent from the bearing to the upper end of the front fitting element.This advantageously results in the longitudinal extent of the extension of the first fitting element, which projects into the substructure, being shorter than the longitudinal extent of the front fitting element from the support bearing upwards.

[0044] Regardless of the geometry of the extension of the front fitting element, it is advantageous for its end to be hinged to a crossbar and also advantageously supported there. Depending on the design, only one crossbar may be provided, to which both ends of the first fitting element are hinged. This is advantageous because it allows for cost savings.

[0045] As explained above, each seating unit advantageously has two pairs of fitting elements spaced apart from each other. A seating unit is advantageously understood to be the unit designed for one user. If the seating and / or reclining furniture described here is not only designed as a single-seat armchair, but also, for example, as a modular seating system, then this system comprises a multitude of seating units. All seating units are designed to be independent of one another. They can be adjusted individually and independently of each other.

[0046] Alternatively, it is also conceivable that the two extension ends of the first fitting elements of a seat unit are each hinged to a separate crossbar. Thus, two crossbars are provided per seat unit, which simultaneously form the coupling links between the lower backrest section and the footrest. Consequently, the crossbars are also part of the force transmission linkage.

[0047] In a further advantageous embodiment, the power transmission linkage also includes at least one drive element for deflecting the linkage. This is advantageous when an even simpler change of the operating position is desired. The drive element can, for example, be a gas spring with a cylinder and piston, with the additional requirement of an electric motor for the corresponding control.

[0048] Furthermore, it is advantageous that the seat remains fixed in position even when the user's position is changed. This is beneficial because only the backrest and footrest are positionally variable.

[0049] In a further advantageous embodiment, the at least one crossbeam is designed as a telescopically movable or fixed-length push rod. This rod is pivotally mounted on the extension of the backrest section via a pivot axis and is pivotally mounted on a U-shaped linkage via a bearing, which also forms a pivot axis. Particularly advantageously, the at least one crossbeam has at least one driver on which the piston of the gas spring or directly an electric motor is arranged as a drive element.When the gas spring is actuated by an electric motor, and the piston extends from the cylinder towards the foot section, for example, it exerts the corresponding force on the drive mechanism. The drive mechanism then changes the length or position of at least one telescopically designed crossbar or at least one crossbar whose length is fixed, thus moving it against the foot section. As a result, the foot section, which also has several fitting elements and a footrest, is pivoted out of its original position so that the feet or lower legs can be placed on it.

[0050] For this purpose, it is advantageous if the U-shaped linkage has two legs connected to each other via a common base, with each leg pivotably mounted at its free end on bearings attached to the substructure and / or the base. Depending on the embodiment, the crossbar is arranged accordingly at the base. If only one crossbar is provided, it is pivotally hinged to the base via a central connection point. This design as part of the force transmission linkage is advantageous because it allows for particularly effective force transmission from the electric motor and gas spring to the foot section. However, at the same time, not only is the foot section deflected from its initial operating position, but also the first backrest section.Naturally, the changes to the usage positions described here are always reversible, so that it is always possible to return from the lying position to the sitting position with a reduced seat depth.

[0051] If, however, two crossbars are provided, these are also pivotally attached to the base. Changing the position of the crossbars also exerts force on the base, causing the attached foot section to pivot accordingly. By providing two crossbars per seat unit, the force can be distributed particularly evenly to the base. This prevents unwanted tilting or shifting of the base.

[0052] In a further advantageous embodiment, the inclination of the drive element in a first operating position of the seat and / or reclining element is greater than the inclination of the crossbeam in the same position. This is advantageous because, with further force applied, the crossbeam can be raised when transitioning to the second operating position, thus resulting in more effective power transmission.

[0053] Furthermore, the seating and / or reclining furniture described here, regardless of the fitting variant, can also feature a safety element that limits the swivel range when an optional drive unit is installed. For example, if the seating and / or reclining element is moved into its second operating position by motor, it has proven advantageous to include at least one safety element. This safety element can detect, for instance, increased resistance and / or a rise in power consumption and intervene in the swivel range executed by the drive unit, stopping it. This ensures that extremities, especially the arms or legs of small children, are not trapped during swiveling. Thus, a particularly safe piece of furniture is provided.

[0054] In all cases used herein, where this formulation is used within the scope of the present invention, the term "essentially" is understood to mean a deviation in the range of 1% to 30%, in particular 1% to 20%, in particular 1% to 10%, in particular 1% to 5%, in particular 1% to 2%, from the specification that would be given without the use of this formulation.

[0055] Further advantages, features and design possibilities will result from the following description of figures illustrating exemplary embodiments, which are not to be understood as restrictive.

A perspective view of a piece of seating and / or reclining furniture; and Fig. 5 a top view from Fig. 4.

[0057] In the drawings, elements designated with the same reference numerals are essentially equivalent to one another, unless otherwise indicated. Furthermore, components that are not essential for understanding the technical teaching disclosed herein are not shown or described. Additionally, reference numerals are not repeated for all elements already introduced and illustrated, provided that the elements themselves and their function have already been described or are known to a person skilled in the art. Detailed description of exemplary implementations

[0058] Fig. Figure 1 shows a sectional view of a fitting 1. The fitting is designed in multiple parts. The fitting 1 initially comprises a lower fitting part, which advantageously has at least two fitting elements 4a, 4b arranged at a distance from each other. Advantageously, a rear, outer fitting element 4a and an inner fitting element 4b spaced apart from it are provided. Both fitting elements 4a, 4b are pivotally mounted to the latching fitting carrier 6 via bearings 8, 10. On the opposite side of the fitting elements 4a and 4b, lower bearings 12, 14 are provided, which are arranged on a carrier 16. The two fitting elements 4a, 4b are thus pivotally mounted via the bearings 8 to 14.

[0059] Furthermore, the rear fitting element 4a has an extension section 18. This extension section is advantageously at least partially curved. This improves the leverage. The fitting 1, which here in Fig. Figure 1 shows the first, folded-in operating position. In this first, folded-in operating position, the extension section 18 forms a common contact surface with a stop element 20. The stop element 20 is advantageously a component of the latching bracket 6. Furthermore, the stop element 20 is advantageously fixed in place, so that when the extension section 18 makes contact with the stop element 20, further pivoting of the extension section 18 is prevented. The stop element 20 thus acts as a pivoting travel limiter.

[0060] Furthermore, the fitting 1 shown here has an upper fitting part, which is also designed in multiple parts. Advantageously, the upper fitting part has a first section 22, which is coupled to the free end of the extension section 18 via a pivot bearing 24. In its first operating position, the first section 22 is inclined steeply upwards and backwards.

[0061] The second end of the first section 22 is coupled to the second section 28 of the upper fitting part via a spacer bearing 26. The spacer bearing 26 is rigidly connected to the second section 28, for example, by screws or rivets. The spacer bearing 26 has a laterally projecting extension to which the first section 22 is pivotally hinged. Consequently, the pivot axis formed by the spacer bearing 26 is located below the second section 28 in the first operating position shown here. Due to the design of the spacer bearing 26 and its fixation to the second section 28, when a force K is applied to the latching fitting carrier 6, the force is transmitted in such a way that the second section 22 is lifted via the extension section 18.The resulting application of a compressive force to the second section 28 and its simultaneous coupling with the support 30, which is advantageously designed to extend vertically upwards, causes the second section 28 to be subjected to a compressive force from its essentially horizontal folded-in position and thus erected upwards in the direction of arrow F. At the same time, the locking fitting carrier 6 is displaced rearwards in the device M, thereby achieving the complete erection of the fitting.

[0062] The alignment of the fitting advantageously refers to the transition from the first operating position shown here to the second operating position, whereby the fitting as a whole has a greater longitudinal extent than it does in the Fig. The first operating position shown in Figure 1 is assumed. It should also be noted that the carrier 30 is fixedly arranged on the locking fitting carrier 6.

[0063] Furthermore, it is optionally possible for the inner fitting element 4b to also have an extension section 32, which extends continuously below the support 14. This extension section 32 is advantageous if the fitting 1 shown here is to be arranged on a coupling linkage 44 of a seating and / or reclining furniture, in order to enable a coupled pivoting of the foot section 48 when the corresponding force K is applied to the locking fitting support 6 (see Fig. 3) to contribute to this.

[0064] In Fig. Figure 2 shows a side sectional view of a seating unit 40, which advantageously has two fittings. For the sake of simplicity, only one fitting 1 is shown here. The fitting 1 shown here is depicted in its first operating position. In addition to the fitting 1, whose fitting element 4b has a downwardly oriented extension 32, a substructure 42 of the seating unit 40 is shown. Advantageously, the substructure is later upholstered and thus forms the actual seat surface.

[0065] Advantageously, the coupling linkage 44 is arranged within this substructure 42. The coupling linkage advantageously has two crossbeams 46 in order to provide the most even possible force distribution when changing the operating position.

[0066] Furthermore, it has proven particularly advantageous if the seating unit 40 shown here has, in addition to the fitting 1 described here, a fitting 1a with which the seating unit 40 is designed to be linearly movable in several directions along a substructure of a seating and / or reclining furniture not shown.

[0067] Furthermore, the fitting 1a can also include a rotating element with which the seat unit 40 shown here can be rotated in its position. Advantageously, the fitting 1a has at least one guide unit, which is advantageously formed from guide rails and complementary guide elements. Particularly advantageously, the fitting 1a has two guide units which are essentially offset from each other by 90°, so that both longitudinal and transverse displacement of the seat unit 40, as well as rotation, can be achieved simultaneously.

[0068] Fig. Figure 3 shows a seat unit 40 in the second operating position. In the second operating position shown here, both the footrest 48 and the fitting 1 are shown in their second operating position, i.e., in the unfolded state. It can be seen that the force applied to the locking fitting carrier 6 causes it to pivot backward, and this pivoting simultaneously causes the upper part of the fitting to deflect.

[0069] The extension section 18 has been pivoted upwards from its original position resting against the support element 20. This pivoting, advantageously at least partially along a circular path, also erects the first section 22. In the second operating position shown here, the second section is advantageously designed to rise upwards towards the rear. This ensures a particularly comfortable sitting position.

[0070] Furthermore, the second operating position shown here demonstrates that the second section is pivoted upwards by more than 90° from its original, essentially horizontally folded position. The forward tilt of the second section 28, towards the footrest 48, is particularly advantageous. This allows the second section 28 to provide a particularly comfortable headrest function.

[0071] Furthermore, it is shown that the two fitting elements 4a and 4b do not form a parallelogram of forces, since the locking fitting carrier 6 is slightly inclined downwards and backwards. This combination of inclinations of the locking fitting carrier 6 decouples the two fitting elements 4a and 4b in their pivoting path, and in the second operating position shown, they are no longer parallel to each other. This is also advantageous for the leverage effect of the extension section 18 and the resulting force transmission from the locking fitting carrier to the upper sections 20 and 28.

[0072] Additionally, the footrest 48 is shown in an extended operating position. For this, the power transmission linkage 44 is also deflected and pivoted. Overall, the second operating position shows in Fig. 3. A comfortable and pleasant seating position in which the user, who can sit on the seating unit 40, can assume a comfortable reclining position with raised feet and a significantly enlarged seating area. In the simplest case, the seating unit 40 consists of a seat and a backrest, although this is of course not the only possible configuration.

[0073] Furthermore, an additional fitting 1a is optionally arranged below the seat unit 40. This fitting 1a can have at least one guide unit by means of which the seat unit 40 can be repositioned on the seating and / or reclining furniture (not shown). In this example, two guide units 50, 52 are shown, by means of which both a linear displacement and a rotation of the seat element 30 are enabled.

[0074] Finally, it shows Fig. 4 a perspective view of seating unit 40 from Fig. 3. It can be seen that two fittings 1 are used for this seating unit 40. Both fittings 1 are hinged to the substructure 42 of the seating unit 40 via the lower support 16. In the vertical direction upwards, the two fitting elements 4a, 4b each form the lower fitting part.

[0075] The locking fitting carrier 6 is advantageously designed as a crossbar and serves to absorb force.

[0076] For improved stabilization, the first sections 22 shown here are guided and stabilized by an additional frame, which is formed, among other things, by the supports 30. The upper second section 28 is also advantageously designed as a frame, as this allows for an additional, comfortable headrest function. At the same time, the footrest 48 is also shown unfolded in the operating position shown here. In this perspective, it is also evident that an additional fitting 1a is provided below the seat unit 40, with which the seat unit 40 can be rotated. At the same time, the fitting 1a, as already shown in Fig. 3 described, at least one linear guide unit, advantageously two guide units arranged offset from each other, in order to be able to move the seat unit 40 in different directions offset from each other.

[0077] Finally, it shows Fig. 5 a front view of the perspective view from Fig. 4, where the fitting 1a, which is located below the seat unit 40, is shown again. The section AA shown further corresponds to the illustration in Fig. 3.
