Description

Field of application and state of the art

The invention relates to a hinge fitting for seating furniture, which serves to make from a arranged in a starting position in the side region of the seat support element, usually a cushion cushion, located in an end position in front of the seat leg rest. The invention further relates to a chair with a generic hinge fitting.

A generic hinge fitting in a corresponding seating is from the EP 0931484 known. There, a Umklappgelenk located in the front corner of the seat is described, which allows the folding of a side cushion cushion in a leg rest. Advantages of this basic concept consist in the simple and quick operation, as well as in the fact that the upper side of the cushion cushion, which is usually also used as a head rest, becomes the underside of the leg rest. However, it has proven to be disadvantageous that the cushion cushion must have a width that is to be extended in the lateral state for conventional upholstered furniture forms in order to achieve a sufficient leg support length. Moreover, such is one Swinging joint visible for geometric reasons even in the folded state in the front area of the furniture. Both of these limits the use in the aesthetically demanding upholstered furniture area very much.

From the US 5,035,464 A is a small table known, which is integrated into a piece of seating furniture and can be converted, starting from a storage location in a functional position. For this purpose, a carrier is provided with a series of joints. In the storage position and the functional position, the table surface is aligned upwards. During the transfer, the table surface is temporarily brought into a vertical orientation.

Task and solution

The object of the invention is therefore to provide a hinge fitting, which can achieve the basic advantages of the concept described without the disadvantages of the prior art and thus opens up a universal use space.

This object is achieved with the fact that the hinge fitting has a displacement device, by means of which the end position of the support element over the position determined by the folding hinge position in front of the seat or a seating furniture frame of the chair is displaced. This ensures that the Beinauflagelänge can turn out very generous even with customary, compact dimensions of the support element.

The hinge fitting may be formed as a continuous component. As hinge fitting but also a hardware system is considered, in which the hinge fitting is split into separate assemblies. Thus, for example, one assembly each of such assembly sets form the folding joint and another assembly form the displacement device. These can be attached separately to the mounting points of a chair.

It is also possible to integrate the hinge fitting directly into a seating frame.

The references to the movements of the support member relative to the seat or the seat frame relate with respect to the description of the fitting according to the invention on movements of parts of the hinge fitting, which are provided for attachment of the support element, the seat and / or the frame of the seat piece of furniture and by means of the fitting in the manner described are mutually displaced.

By the inventively provided displacement device, a distance position of the support element in front of the seat can be realized, which gives the legs of a seated user when folding more space and facilitates getting up even when folded leg rest. However, the displacement can also take place together with the seat itself relative to a stationary frame of the seat, so that the seat and the support element in the end position are in contact with each other or are approximately in contact with each other. Furthermore, by means of the displacement according to the invention, a complete concealment of the fitting technology in the starting position can be achieved, which allows the use of the hinge fitting in seating furniture broader market areas. Another advantage is that the displacement device in a first movement phase of the movement of the support element from the starting position to the end position, the support element can shift forward even before it is pivoted by means of Umklappgelenks. This makes it possible to use particularly large support elements which project beyond a front side of the backrest in the starting position to the rear. This can also be advantageous for aesthetic reasons.

The displacement device allows a displacement of the support element or the relevant fastening parts of the hinge fitting beyond that extent, which would be possible by the folding hinge alone.

Preferably, the displacement device is designed to be rotary or translational. Rotary training is technically particularly simple and reliable. With such a rotationally acting displacement device, the support element or the relevant fastening parts of the joint fitting in addition to the pivoting about the axis of the folding joint can be further pivoted.

If the rotary displacement device has an axis of rotation which is arranged below the surface of the seat, in particular in the front region of the seat near the floor, approximately parallel to the front surface of the seat, a geometrically particularly favorable displacement can be achieved. With regard to the hinge fitting this is preferably designed so that it can be fastened to the seat or on the frame of the seat, that said alignment or arrangement of the axis of rotation of the displacement device can be achieved.

For certain applications, a translational design of the displacement device is expedient. With such a translationally acting displacement device, the parts adjoining the displacement device and moving relative to each other by the displacement device are movable relative to one another along a track which is not defined by a pivot axis. This movement path can be straight or curved.

A translational displacement device preferably includes a rolling or sliding guide. This can be, for example, on or in the seat base frame or support element or in the field of related fasteners of the hinge fitting.

A displacement device according to the invention can also form a sliding device for the seat at the same time, be part of such or be combined with such.

In such a design, the seat or the seat provided for fastening parts of the hinge fitting, such as a seat frame, in particular together with the folding hinge forward displaced, in particular using a rolling or sliding or using shift levers. As a result, the seat is opposite the seat piece of furniture in an extended functional position.

Said rolling or sliding guide is preferably oriented approximately horizontally. The alternatively usable displacement levers are preferably at least two displacement levers with spaced apart pivot axes, which together allow a parallel or approximately parallel displacement of the seat. By a deviation from the parallelism, an ergonomically favorable pivoting of the seat can be effected.

In known manner, the seat back and the backrest can be coupled. For this purpose, the hinge fitting is designed such that it can also influence the position of the backrest and has for this purpose fastening parts for connecting the backrest. With such training, a particularly favorable ergonomics and aesthetics can be achieved.

In a further embodiment, the displacement device has a movable support arm. This support arm is movable relative to the attachment of the hinge fitting on the seat or on the seating furniture frame.

On the one hand, it can be arranged between the hinged joint and the parts intended for attachment to the seat or seating frame be. In this case, it can be displaced forward by the displacement device together with the folding joint. On the other hand, the support arm between the folding hinge and the support element can be arranged. In this case, the Umklappgelenk be fixed to the seat and it is displaced, the support element on the support arm. In both ways, simple, stable and subtle implementations can be achieved.

Parts of the displacement device, in particular its movable support arm are provided in a further embodiment to emerge from a located between the seat and a fixed to the seat or fixed to the seat frame side seatback of the seat or a slot or opening at the top of the seat. The former option is particularly universal, since this slot is already present in most seating furniture forms. The second possibility is useful for common seating forms, especially for those who have no separate side part.

It is also possible to provide the displacement device as a lateral conclusion of the piece of seating furniture. In such a case, the displacement device is not hidden, but on the contrary deliberately shown to make their functioning recognizable.

In a further embodiment, one or more joints of the hinge fitting are formed such that the parts moving against each other by them are supported directly or by means of a thrust bearing together. With such a design, the transmission of bending moments thus does not take place primarily via a radial bearing, for example on an axle element. Instead, the mutually movable by the joint portions are pressed together by means of a pulling means such as a bolt in order to achieve a transfer of the bending moments, which does not occur substantially over the bolt.

This represents a so-called axial bearing and is compared to a radial bearing a particularly space-saving and affordable solution.

Furthermore, the hinge fitting preferably has at least two in particular internal end stops, one of which limits the mobility of the folding joint and the other of which limits the mobility of the displacement device in the end position. Thus, this end position is well defined and a risk of injury is effectively prevented. Furthermore, it is also possible to provide end stops for each of the two directions of movement of the folding joint and / or the displacement device, this being achievable by a limit stop acting in two directions or by two end stops acting in one direction. This bidirectional design of the attacks is advantageous because it can define the position of the support element both in the starting position and in the end position. It is thus achieved, in particular, that during the transfer of the support element from the end position, an undesired alternative starting position is not reached, in which either the folding joint or the displacement device is moved beyond the intended starting position, while the other of the elements does not reach its intended starting position ,

The hinge fitting can also be supplemented by an angle adjustment. This can in particular be designed as a per se known Reiboder latching fitting, which is then preferably to be arranged between the support members for the support element and the folding hinge. The angle adjustment allows in addition to the folding hinge and in addition to the displacement device, a movement of the support element or at least of parts of the support element. In this way, or can the support element or the relevant fastening parts in the initial position of the hinge fitting, in which the support element is arranged in the side region of the seat piece of furniture to be completely or partially pivoted in addition to the other parts of the hinge fitting, in particular to a relative to the piece of furniture from front to back extending pivot axis, so that the support element its side back function in the starting position in aesthetically particular can fulfill advantageous form. Also allows the angle adjustment, to use the support element in the initial position of the support element in different conditions of use.

For an angle adjusting device acting only partially on the position of the support element, the angle adjustment device can preferably connect a plurality of support parts of the support element or the relevant fastening parts of the fitting to one another in order to thereby preferably achieve a particularly flexibly adjustable shape of the support element.

Preferably, the displacement device of the hinge fitting is adapted to herunterzuverlagern the end position of the support element relative to its initial position in height. The displacement device is therefore designed such that, starting from an already pivoted Umklappgelenk the displacement of the support element in the closed end position is accompanied by a lowering of the support element. On the one hand, such a design is advantageous because a lowered leg rest is desirable for ergonomic reasons. In addition, this reduction and thus the achievement of the end position are achieved automatically due to the weight of the support element.

Furthermore, it is advantageous if the hinge fitting has fastening parts for a wooden plate to be arranged in the support element or a wooden frame, wherein the fastening parts in particular flange parts are, which are provided for mutual clamping and / or screwing a wooden plate or a wooden frame. The use of such a wooden plate and a suitable hinge fitting is advantageous because such a wooden plate is quite easy to cushion and since in such a design of the hinge fitting must not be adapted to the size of the support element used in the individual case. Instead, it is designed to accommodate any size plates and thus universally applicable.

The invention further relates to a chair, in particular a sofa, with a base fixed to a base frame, with a seat and with a support element, wherein the support element by means of a hinge fitting with folding hinge from a respect to the seat laterally arranged starting position in an end position located in front of the seat can be folded down as a leg rest, wherein the upper or lateral surface of the support element in the initial position represents its lower surface in the end position.

According to the invention the hinge fitting of such a generic piece of furniture is formed with a hinge fitting of the type described above. In such a seating furniture according to the invention thereby at least one of the hinge fittings described application. In a sofa are preferably two hinge fittings according to the invention, which serve for the independent displacement of two support elements.

With regard to the configuration of the at least one hinge fitting and its attachment to the other components of the piece of seating furniture, all variants described above for the hinge fitting according to the invention are conceivable.

The invention further relates, in particular as a development of said seat according to the invention, a generic piece of seating furniture in which the hinge fitting is designed such that the support element is arranged spaced in the end position of the seat and / or that the folding hinge at least in the starting position on the back of a front seat edge the seat is arranged.
It is particularly advantageous if the displacement device is designed and arranged relative to a center of gravity of the support element, that causes starting from the initial position, a folding of the support element about an axis of the folding hinge, that the displacement device assumes its end position, and that starting from the end position a folding of the support element about the axis of the folding joint causes the displacement device assumes its initial position.

With such a design, the folding operation on the folding joint thus also controls the displacement device by utilizing the center of gravity of the supporting element. When the support element is pivoted in the direction of its end position, the center of gravity of the support element acts so that the displacement device completes the end position, for example because the center of gravity is then positioned in front of a rotational axis of a rotary displacement device. If the support element is then pivoted back in the direction of the starting position by means of the Umkappgelenks, is hereby effected, and the displacement device is moved back again in the direction of the starting position, since the center of gravity is then arranged, for example, behind the axis of rotation.

Such designs can be realized in particular with a hinge fitting according to the invention. Basically, however, embodiments of a sofa with the features mentioned are included, in which the hinge fitting realized the displacement of the support element alone on the folding hinge.

The arrangement of the support element in a position spaced from the seat in the end position has the advantage that a particularly long contact surface is achieved without necessarily requiring a particularly large support element for this purpose. Instead, by the distance of the support element between a seat-side edge of the support element and a pad-side edge of the seat, which is preferably at least 5 cm, in particular preferably 15 cm, provided an interrupted support surface through the seat and the support element together. The distance does not interfere with this in practice. It is comparable to the distance that is usually left between the seat and the stool even when using a separate stool.

The arrangement of the folding hinge back of a front seat edge of the seat makes it possible to hide the folding hinge on the one hand for aesthetic reasons. In addition, by such an arrangement in which the axis of the folding hinge on the folding joint is preferably displaced by at least 5 cm relative to the front seat edge in the furniture longitudinal direction to the rear, but also ensures that the risk of injury in the hinge fitting, especially at the folding joint, is reduced , In such a recessed arrangement of the folding hinge, it is particularly advantageous if a displacement device above beschriener type is provided on the hinge fitting. However, there are also designs without such a displacement device possible, in which preferably a support arm is rigidly provided on the support element, which connects the folding hinge with the support element and which has at least one length corresponding to the distance to the folding over the front seat edge is reset.

In this document, the articles are not understood as a number word and can, as well as the nouns, singular and plural in the individual case. Local terms such as "in front of the seat" or "sideways to the seat" are understood in the generally accepted sense, ie from the perspective of a user standing in front of the seat or sitting on it.

Detailed description of the embodiments

FIG. 1 shows an inventive piece of seating furniture, which is designed as a sofa 10. This piece of seating furniture 10 has two support elements 12, which are convertible from a starting position in which they are arranged as a cushion pad located laterally to a seat 14 in an end position in which they are arranged as a leg rest in front of the seat 3.

On the right side of the sofa, a first hinge fitting 20 can be seen together with the supporting element 12 attached to it in the unfolded end position. On the left side is a mirror image, but otherwise identically constructed second hinge fitting 20 with attached to it support element 12 in the retracted initial position to see.

The hinge fittings 20 each have a folding hinge 30, by means of which the respective support element 12 can be folded from the starting position to the end position. The axes 32 of the folding joints 30 are obliquely in space. In this embodiment of the Fig. 1 the folding hinges 30 and thus the axes 32 are not arranged with respect to their position fixed to the seat 14 of the piece of seating furniture, as will be explained below.

The location and / or orientation of the axles 32 in the space depends on the desired angles 12a, 12b, about which the support elements 12 should be inclined in the starting position and the end position with respect to an imaginary horizontal plane.

The hinge fittings 20 have on the side facing away from the seat 14 each have support members 22, 23, which serve to attach the support element. In the embodiment of Fig. 1 These support members comprise a support frame 22, which is attached by means of a non-movably attached flange member 23 on the folding joint 30. Of the Support frame 22 and the flange 23 are thus mutually movable relative to the parts of the articulated fitting 20 which lie opposite one another with respect to the folding-over joint 2.

At in Fig. 1 not shown alternatives, the support members may also be formed strip-shaped or plate-shaped.

As in addition to the folding hinge 30 central element of the hinge fittings 20 each have a rotary displacement device 40 is provided. This displacement device 40 has a movable support arm 46, at whose in Fig. 1 lower end, a rotary joint 44 is provided, by means of which the support arm 46 is pivotable about a rotational axis 42 relative to a flange 24. This flange part 24 is fastened, for example, by means of screw connections to a frame 11, indicated by dashed lines, of a frame of the seat 10. The attachment to this preferably of plates, in particular of wood panels, composite frame 11 leads to a very simple construction, combined with a high stability.

The axes of rotation 42 of the displacement device 40 run in the interior of the chair 10 in its front area near the floor and preferably substantially parallel to a furniture transverse axis 1, which extends in the direction of the seat width. Depending on the type of seating furniture piece and a position of the rotation axis 42 relative to the furniture transverse axis 1 to 30 ° may be appropriate.

The rotation axis 42 can also be arranged further above, in particular on an upper edge of the frame 11. In such a case, a larger swing angle of the support arm 46 about the rotation axis 42 is required for the same amount of horizontal displacement as in the illustrated embodiment.

With the exception of the frame-fixed components, in this case the flange part 24, all parts of the hinge fitting are pivotable about the rotation axis 42 together with the support arm 46. By a pivoting movement can thus be pivoted by means of the support arm 46 and the Umklappgelenk 30 with the support member side support members 22, 23 and the support member 12 in a horizontal or sloping circular arc portion forward and thus from the seat 12 away.

By this enabled by the displacement device 40 pivoting movement is in the in Fig. 1 right end position shown a distance 8 between the seat 14 leading edge and the edge of a seated person facing edge of the support element 12 achievable.

The support element 12 is thus comparable in this end position a stool arranged in front of a piece of seating furniture, but with the advantage that the support element 12 can be moved back to the starting position of the left side at any time.

In addition to this ergonomic quality, the displacement device 40 also causes the folding hinge 30 to be arranged behind the front end edge of the seat 14 in the starting position of the hinge fitting 20 shown on the left and thus completely hidden. Only by the displacement device 40 is it brought into a position arranged in front of this end edge.

It is furthermore of particular ergonomic advantage that the respective center of gravity 13 of the two support elements 12, when the support element 12 is not yet pivoted about the respective axis 32, is behind the respective rotation axis 42 and already pivoted about the axis 32 Support element 12 is arranged in front of the respective axis of rotation 42. This results in that a targeted influence on the displacement device 40 is not required, since this happens almost automatically: Depending on the pivotal position of the folding hinge 30, the displacement device 40 takes the in Fig. 1 left or the in Fig. 1 right position.

Also, a retention of the displacement device 40 and the support element 12 in both positions is thereby effected, without thereby spring or locking elements would be required.

The support arm 46 has an angular and / or curved shape. A part of the support arm 46 facing away from the rotary joint 44 extends approximately equidistantly to the rotation axis 42, so that it is not readily apparent from the outside when the support element 12 is transferred to the distortion shown on the right that the displacement device 9, 10 is designed as a rotary displacement device is.

It is particularly advantageous that the displacement device 40, in particular the support arm 46 of the displacement device 40, moves exclusively in the plane of the furniture piece vertical axis 2 and the furniture longitudinal axis 3, so that it can move in a vertical slot 16, which in any case between the seat 14th and an side rest 18 is provided.

For certain types of seating furniture, in particular for a seat without seat back, not shown, it may also be useful to guide the arm through an opening in the front part of the seat surface. It may also be expedient to move the support arm laterally of the seat. Thus, the support arm and its operation can be detected easily.

In a variant of the embodiment of the not shown Fig. 1 the displacement device is replaced by a translational displacement device. In this case, the support arm is also provided, but movably mounted relative to the frame of the seat piece of furniture, in particular by means of a sliding or rolling guide. In this case, the career, along which the support arm is guided, preferably guided in a curved manner to about the same Fig. 1 to simulate described movement of the folding hinge 2, wherein the support element is lowered in the direction of the end position. This translational variant of the hinge fitting takes up less space in furniture vertical direction 2, so that it can be advantageously provided, for example, in a piece of seating furniture in which, due to higher legs than the seating piece of furniture Fig. 1 would disturb a nearly to the ground extending displacement device.

Fig. 2 shows in an enlarged view the hinge fitting 20 with rotary displacement device 40 of Fig. 1 ,

For attachment to the frame of the furniture, the flange 24 is provided. For this purpose, fastening bores 25 are provided, in particular for screws on the flange part 24. By means of the rotary joint 44, the other parts of the hinge fitting 20 with respect to the flange 24 are pivotable about the rotation axis 42. Immediately to the joint 44, the support arm 46 connects with preferably rectangular cross-section, which has a radially extending first portion 46 a and a curved and equidistant from the axis of rotation 42 extending second portion 46 b. At a bent end 46 c of this second portion 46 b of the support arm 46, the folding joint 30 is provided, which allows pivoting of the support element 12 about the axis 32 relative to the support arm 46. The folding joint 30 is for this purpose between the support arm 46 and the Support members 22, 23 are provided which serve the attachment of the support element 12. These support members are the flange portion 23 and the support frame 22. By the bend of the end 46c of the support arm 46, the desired alignment of the axis 32 is achieved.

The folding hinge 30 and the rotary joint 44 have an axial bearing, which is formed by a zuglaught bolt 31 a via a sliding disc 31 b, the end faces of the bent end 46c of the support arm 46 and the flange 23 pressed against each other. This axial bearing is thus supported via these end faces against bending load. This axial bearing can be particularly short in the direction of its bearing axis 32 and is therefore particularly suitable for receiving in the corner region of the support element 12.

Both joints 30, 44 are equipped with an internal stop for the end positions. For this purpose, an end face has an arcuate groove concealed against the risk of injury and into which a bolt engages on the other end face.

The Fig. 3a and 3b show how Fig. 2 a hinge fitting 20 '. This differs only in terms of details of the hinge fitting 20 of Fig. 2 and is therefore provided with the matching reference numerals.

Notwithstanding the hinge fitting 20, the hinge fitting 20 'on no support frame 22. Instead, two retaining plates 22 'with holes for screws are provided on the flange part 23. These holding plates are used to hold a plate, such as a wooden plate, in Fig. 3a indicated by dashed lines. Such a plate is comparatively easy to provide with a padding. Moreover, the advantage of such a hinge fitting 20 'with retaining plates 22' is that regardless of the size of the support member 12 of the same hinge fitting is used, since this has no elements that of the Size of the support element are dependent. Such a hinge fitting 20 'can thus be used more universally.

Furthermore, the hinge fitting 20 'differs from the hinge fitting 20 by the nature of the stop design. Both on the flange part 24 and on the support arm 46 are eccentric to the joints 30, 44 bolts 38, 48 are provided which cooperate with abutment surfaces 39a, 39b and 49a, 49b, so that the mobility of the flange member 23 relative to support arm 46 is also bidirectionally limited as well as the mobility of the support arm 46 relative to the flange 24. The bidirectional limitation means that both the starting position and the end position of the hinge fitting 22 'is clearly defined and not by the hinged on the hinge fitting 22' other parts of the sofa are determined.

In a further embodiment of a piece of seating furniture 110 according to the invention Fig. 4 with a hinge fitting 120 according to the invention, a translational displacement device 140 is provided instead of the rotary displacement device.

The piece of seating furniture that is in Fig. 4 is shown, each hinge fitting 120 a folding hinge 130, which is mounted in each case stationary to a part of the frame 111 of the piece of furniture 110 shown only partially. This folding joint 130 allows pivoting of the remaining parts of the hinge fitting 120 and thus also a support element 112 about an axis 132, which in turn is arranged obliquely in space and extends substantially in the plane of the furniture longitudinal direction 3 and the furniture transverse direction 1. Beyond the hinged joint 130, a support arm 122 is provided, which is part of the displacement device 140. This displacement device 140 is provided as a translational displacement device and has for this purpose a rolling guide 142, which between the support arm 122 and a support frame 123 is provided for attachment of the support element 112. The rolling guide 142 is disposed within the support member 112 and thus hidden opaque.

The displacement device 140 allows a displacement of the support element 112 relative to the approximately J-shaped support arm 122. This displacement takes place in the extension direction of two mutually parallel sections 122a of the support arm 122. In this shift, the support member fixed support frame 123 is moved relative to the support arm 122, wherein a portion of the support arm 122 emerges from the support member 112, while the support member 112 is displaced forward, so again a distance 8 between the front edge of the seat 114 and the in Direction of a seated person facing edge of the support member 112 is effected.

Similar to the embodiment of the Fig. 1 Due to the angle 112a, 112b, with respect to which the support element 112 and thus also the rolling guide 142 is inclined in the starting position shown on the left or the end position shown on the right relative to a horizontal plane, comes it is the manual pivoting of the support member 112 about the axis 132 for automatically always downwardly directed displacement of the support member 112 relative to the support arm 122nd

As in the left side of the piece of seating furniture Fig. 4 can be seen, all fitting parts of the hinge fitting 120 are hidden in this position in the seat or in or under the support member 112.

In a variant, not shown, the translational displacement device 140 is replaced by a rotative. Instead of the rolling guide 142 could For example, be provided for this purpose a rotary joint. An axis of rotation 180 of this rotary joint would in this case pivotally connect a front end of the support arm 122 to the support frame 123. Around this axis of rotation 180, the support element 112 can then pivot along the support arm 122 toward the folding joint 130 or away from it and reach the displacement according to the invention. Related to the representation of the Fig. 4 For example, the support element would pivot about the rotational axis 180 by about 15 ° in the end position after transfer of the Umklappgelenks 130 in its end position, thereby achieving the end position represented.

Fig. 5 shows a further embodiment of a piece of seating furniture 210 according to the invention with hinge fittings 220 according to the invention. The hinge fittings 220 are in turn formed as hinge fittings 220 with translativer displacement device 240, but have the peculiarity that the displacement device 240 at the same time a displacement device for one seat 214a, 214b of the Seating furniture 210 represents. The seat 214b is provided for this purpose fixed to a seat frame 250. This seat frame 250 is displaceable by means of a rolling guide 252 with respect to a stationary remaining frame 211 of the seat 210 and frame-side guide rails 224 in the furniture longitudinal direction 3. As an alternative to such a rolling guide 252, other displacement mechanisms for the seat frame 250 are possible, such as a sliding guide or a linkage to rocker arms, which are articulated on the one hand on the frame and on the other hand on the seat frame.

Preferably, the rolling guide 252 or an alternative displacement mechanism is designed such that upon a displacement of the seat frame 250 forward simultaneously enters a slight tilting movement, as in Fig. 5 is illustrated by the level difference 254.

Mounted on the seat frame 250 is a hinged joint 230 which, in a similar form as in the preceding embodiments, permits pivoting of a support element 212 about an axis 232 arranged at an angle.

In the illustrated embodiment, the folding hinge 230 is not fixed to the seat frame 250, but instead to an intermediate member 260, which in turn is pivotally mounted about a rotation axis 262 on the seat frame 250. The advantage of this intermediate element 260 is that it is in the on the left side of the seat piece of furniture Fig. 5 illustrated manner allows to hide the folding hinge 230 in this initial position particularly well.

To achieve a particularly simple design, in a variant, not shown, the folding joint 230 may also be arranged fixed to the seat frame 250, and be provided so firmly on this.

Notwithstanding the preceding embodiments, no distance between the seat 214b and the support element 212 is generated in this embodiment by means of the displacement device 240. Due to the displacement of the seat 214b forward through its connection to the hinge fitting 220 but still a large leg rest length is achieved.

By including a means of hinges 270 to the seat frame 250 pivotally hinged backrest frame 272 in the hinge fitting 220, a coupling of the backrest 215 to the displacement device 240 is also achieved.

In a variant, not shown, for the embodiment of Fig. 1 the fitting 20 remains unchanged, while still a displaceability of the seat in the nature of the rolling guide 252 is given, so that independently each other, the support element 12 and the seat 14 are displaced. However, a further variant based on this can be achieved by slight modification of the fitting 20 of the Fig. 1 be formed so that the seat 14 is still coupled in terms of its movement to the movement of the support member 12 by, for example, at the portion 46 a of the support arm 46, a projection is attached, which engages the seat frame of the movable seat.
