Description

The invention relates to a upholstered furniture according to the preamble of claim 1.

Such upholstered furniture are for example from the US6341392B1 or the DE801527C known and have a base member and a seat member with a seat cushion, which is connected to the base member. The connection between the base member and the seat member is made by guide elements in a manner that allows the seat member to be reciprocated by a combined translational and rotational movement between a first position and a second position. These are preferably in the first position to a seating position in which the upholstered furniture can be used as seating. The second position is preferably a reclining position that allows the upholstered furniture to be used as a sleeping place.
In this case, there is regularly the desire to transfer the upholstered furniture in the simplest possible way from one position to the other position. At the same time, the upholstered furniture should also offer a stable stability, especially in a lying position. According to the prior art, this regularly separate support elements must be swung or extended, or it is necessary to move the entire upholstered furniture or only parts of the upholstered furniture on the floor surface. In particular carpets and the like, which lie directly on the floor surface from the front of the upholstered furniture, often have a disturbing effect and must first be removed.

The invention is therefore based on the object to provide a upholstered furniture, which can be moved back and forth in a simpler manner from a first position to a second position.

The object is achieved by a upholstered furniture with the features of claim 1. The features of the dependent claims relate to advantageous embodiments.

According to the invention, the upholstered furniture is designed in such a way that a section arranged at least at the rear part of the seat element undergoes an approximately S-shaped trajectory during the movement from the first position to the second position, which results in a support element arranged on the seat element initially being spaced apart moved from the footprint of the base element corresponding floor level in the direction of the front of the upholstered furniture. Only after exceeding a predetermined distance, the support element lowers to the ground level. For this purpose, the support element is preferably rigidly connected to the seat element.

Due to the movement guidance of the seat element according to the invention and the support element located thereon, it is achieved that the support element can initially be moved over an obstacle, such as a carpet edge, which is located immediately in front of the seating furniture during the movement. As a result, the frequently encountered situation that a lying directly in front of the chair carpet is an obstacle in the transfer of the chair from the first position to the second position, in particular in a sleeping position, overcome. When the support member is lowered onto the carpet after passing the carpet edge, the support member may move on the carpet as on a normal floor surface. The support element is here preferably designed as a support roller, so that a rolling of the support member on each substrate is possible without it depends on the sliding properties of the support member on the respective substrate.

The upholstered furniture preferably has a lower guide element. This is preferably arranged on the base element. Particularly preferred are two lower guide elements, which are arranged in parallel. Two lower guide elements lead to a stabilization of the upholstered furniture.

An advantageous design of the upholstered furniture, which enables the movement of seat element and support element according to the invention, relates in particular to the design of the guide elements. The design of the guide elements, the relative movement of the seat member to the base member can be selectively influenced, in particular, a superposition of the substantially translational movement of the seat member to the front side, ie forward, by a rotational movement possible. This can be effected in an advantageous manner by curvatures of a guide element. In this advantageous embodiment of the upholstered furniture, the portion arranged at the rear part of the seat element is a rigid connecting element between the seat element and a guide counter element, which is guided in the lower guide element. By the rotational movement component, it is now possible to lower the front portion of the seat member after covering the predetermined distance to bring the support member in contact with the ground.

In a further advantageous embodiment of the upholstered furniture, the combination of translational with the Rotational movement can be generated by the fact that the translational movement takes place first along a guide element. Here, the arranged on the rear part of the seat member portion is additionally movably coupled to a connecting element. The connecting element in turn is guided with the free end by means of a guide counter-element on the lower guide element. At the end of this movement section, the connecting element is rotated about the guide counter-element, so that in total the section arranged at the rear part of the seat element performs an approximately S-shaped movement.

The upholstered furniture preferably has a back element carrying a backrest cushion. This is advantageously hinged to the seat member and the base member such that it is also reciprocated from the first position to a second position by the movement of the seat member in a combined translational and rotational movement relative to the base member. In the first position, which is advantageously a seating position, the useful surface of the backrest cushion is preferably in a slightly inclined backwards, but substantially upright position. In contrast, in the second position, the useful surface of the pad of the back element is preferably in an at least substantially horizontal position.

Preferably, the upholstered furniture, in particular the articulated connection of the back cushion with the seat element and the base element is designed so that the back element in the first position has the smallest distance to the back of the upholstered furniture. In this case, the first position is preferably an end position of the movement region of the back element. Such a design makes it possible to position the upholstery with its back flush against a wall. If the upholstered furniture is now transferred from the first to the second position, the back element moves away from the wall from the first point of the movement so that the wall does not interfere with the change in position. On the other hand, according to the prior art, upholstered furniture of the type in question often has to be removed from the wall in order to allow a change in the position of the elements of the upholstered furniture, in particular a transfer from a sitting position to a lying position. However, this is awkward for the user and thus disadvantageous.

It is advantageous if the upholstered furniture has a drive for moving the seat element. This drive is preferably a linear drive. Advantageously, spindle drives can be used here, these are characterized in particular by the fact that they can handle comparatively large forces. This also makes it possible, in particular, to change the position of the upholstered furniture, in particular of the seat element, while a person uses the upholstered furniture. Such drives are powerful enough to move the seat member with a lying or sitting on this person. Such, in particular electric drive can also be used in a simple and elegant way, especially if the necessary controls are hidden by cushions attached.

Particularly preferably, the padding element has a footrest element. Such a foot support element serves to deposit the feet and is preferably also movable back and forth between a use position and a non-use position. In its non-use position, the effective area of the footrest element preferably takes an in Essentially vertical position, while the footrest element occupies a position in particular in its use position, in which the useful surface, at least substantially, is aligned horizontally. The footrest member is preferably attached to the seat member, which has the advantage of moving in concert with the seat member as the seat member is moved. Preferably, the footrest element is designed such that it can be moved between the use position and the non-use position via one or a plurality of intermediate positions; in a preferred stepless adjustment of the footrest element this is actually an arbitrary multiplicity of intermediate positions. Such intermediate positions have the advantage that in addition to the use position further possible positions are generated in which the feet can be stored in alternative positions.

To move the footrest element, the upholstered furniture preferably has a footrest drive. In this case too, it can preferably be a linear drive, in particular a spindle drive. The footrest drive serves to move the footrest between its use position and its non-use position. The preferably electric footrest drive preferably has control elements assigned to it, with which it can be actuated independently of the rest of the upholstered furniture, in particular the control of other drives of the upholstered furniture. This allows the user to combine different positions of the foot support member with different positions of the seat member and advantageously also the back member together, which increases the versatility of the upholstered furniture.

The upholstered furniture is advantageously designed such that the seat element passes through a third position on its path of movement between the first position and the second position. This third position is preferably a relaxation position. This is understood to mean, in particular, a position in which the useful surface of the seat element or the upholstery of the seat element drops toward the back of the upholstered furniture or falls more sharply than in the first and / or the second position. It is advantageous if the passage through the third position is also performed by the back element, which has a greater inclination of its effective area in the third position than in the first position.

It is also true for this movement that the movement between the first position and the second position is preferably a stepless movement, that is to say that an unspecified plurality of corresponding intermediate positions are passed through. This makes it possible, in the selection of the third position by the user of the upholstered furniture, to select a third position which best suits his current needs.

This movement of the seat element is made possible in particular by the design of the guide elements. These may preferably be guide rails, in particular with a C-shaped cross section. It is advantageous if each guide element cooperates with at least one guide counter-element. The guide counter element is preferably a guide roller.

On the one hand, a particularly advantageous combination of a guide rail with a C-shaped cross section and a guide roller has the particular advantage that the Guide elements may have curvatures. Such curvatures make it easier to realize the movement sequences according to the invention.

Preferably, the lower guide element and the lower guide elements on two opposite bends. These preferably give the guide element an at least approximately S-shaped profile. Such a course makes it possible to bring about the movement of the seat element according to the invention, in particular to ensure that the seat element firstly experiences a lowering of the rear area of its usable area during its forward movement, which is then raised again after passing the rear bend by the guide counter element , By raising the rear portion of the seat member, the seat member preferably performs a tilting forward rotational movement, which in particular causes the support member is lowered to the ground level. In the further course, i. Before or front side of the front bend, the lower guide element preferably has an approximately horizontal to the front of the upholstered furniture, possibly slightly sloping course. During the movement over this route section, the support element is preferably already in contact with the ground.

On the other hand, another particularly advantageous combination of a guide rail with a C-shaped cross section and at least one guide roller has the particular advantage that the sequence of movement of at least the rear part of the seat member arranged portion which is arranged in this embodiment to a connecting element, are divided into two parts can. Initially, the arranged portion moves forward parallel to the guide member. In this case, the connecting element, which is at both ends is movably mounted, forcibly guided by means of a second lower guide counter element, which is also guided in the guide element. Particularly preferably, a third lower guide counter-element is attached to the connecting element so that it rolls on the latter during the movement along the guide element. In this case, the third lower guide counter element is preferably, viewed from the first guide counter element, arranged behind the second lower guide element. This arrangement stabilizes the positive guidance, in particular in the front portion of the guide element. Most preferably, the seat element undergoes a lowering of the rear portion of its effective area during its forward movement, which is based on the fact that the guide element is also lowered towards the front. In this case, the guide element can be straight or slightly curved.

At the end of this movement section, the first guide counter element abuts against the end boundary of the guide element. In this case, the C-shaped guide element is recessed in the region of the second lower guide counter-element upwards, so that the connecting element, with the arranged at the rear of the seat member portion and the arranged second, and optionally third, lower guide counter-element, around the first lower guide member can turn upwards and so continues the approximately S-shaped movement of the arranged portion and thereby lowered the support element to the ground level.

In a particularly preferred embodiment, a guide aid is mounted on the guide element immediately adjacent to the recess, which supports the second lower guide element at least in sections during the rotational movement of the connecting element. In the execution with the third lower guide counter-element, the guide aid, which is preferably arranged in front of the recess for the second lower guide counter-element, are provided with a ramp on which the third lower guide counter-element in the last portion of the translational movement initiates the rotational movement of the connecting element by being guided up the ramp ,

In addition to the lower guide element or to the lower guide elements, the upholstered furniture preferably has an upper guide element arranged above the guide element. It is understood that the upholstered furniture advantageously also has two upper guide elements. These are preferably arranged in pairs in the lateral regions of the upholstered furniture in its width direction. The upper guide element or the two upper guide elements are preferably arranged on the seat element. The corresponding guide counter-element is preferably located in the front region of the base element.

It is advantageous if the upper guide element has a straight course. In this case, the upper guide element particularly preferably faces the front side of the upholstered furniture at a greater distance from the useful surface of the seat element than towards the rear side of the upholstered furniture. This results in a slight lowering over the movement path of the seat element, which is advantageous with regard to the overall movement guidance, in particular to the lowered position of the support element in the second position.

That in the FIGS. 1 to 11 illustrated exemplary upholstered furniture 1 according to the invention comprises a base element 2, a seat element 3 and preferably a back element 4. The seat element 3 has, for example, a structural element 20 and a padding element 21. The left part of the structural element 20 corresponds to the portion 25 which is arranged at the rear part of the seat element. These subdivisions are only schematic and greatly simplified and should at this point essentially lead to simplify the traceability of the function based on the figures. The same applies to the back element 4, which is composed, for example, of a structural element 22 and a cushion element 23. In the Fig. 1 to 4 and 9 to 11 the upholstery elements 21 and 23 are shown. In the Fig. 5 to 8 however, only the structural element 20 of the seat element 3 and the structural element 22 of the back element 4 are shown. This is intended above all to facilitate the recognizability of the relative spatial arrangement of the individual functional elements relative to one another. In addition, the figures represent only one half of the invention Upholstered furniture 1, wherein the sectional plane of the representation is placed in each case immediately adjacent to the centrally arranged drives 13 and 11. The position of the cutting planes was set in the individual illustrations so that the drives 13 and 11 are still covered by the illustration; in other figures, the cutting plane was laid in such a way that the drives are not part of the image and thus do not prevent the visibility of other elements that would otherwise be obscured by the drives.

The seat member 3 is connected to the base member 2 advantageously by a pair of lower guide members 5 and a pair of upper guide members 6. In the example shown, the lower guide elements 5 have an advantageously approximately S-shaped profile. The upper guide elements 6, however, are straight and have a greater distance to the effective surface 7 of the seat element 3 in the front region than in the rear region.

The back element 4 is connected in an advantageous manner via a first link 8 to the base element 1 and in a particularly advantageous manner via a second link 9 to the seat element 3. In the example shown, the first link 8 and the second link 9 are preferably bent.

A foot support element 10 is pivotably connected to the seat element 3 in the region of the front end of the useful surface 7. The foot support member 10 may advantageously by a footrest drive 11 between the in Fig. 11 illustrated non-use position and the example in the Fig. 9 shown use position to be moved back and forth. The footrest drive 11 is accommodated in an advantageous manner approximately in the middle of the upholstered furniture. Such as in the Fig. 2 until 11 can be seen, the footrest element 10 is connected both by the footrest drive 11 as well as by a link assembly 12 with the seat member 3. When the footrest element 10 is loaded, the load received by the footrest element 10 is introduced via the footrest drive 11 and the handlebar arrangement 12 in the seat element 3 such that the footrest drive 11 carries the predominant part of the weight force to be introduced into the seat element 3.

An advantageously also approximately centrally arranged drive 13 - also for example in Fig. 9 or 10 to recognize - causes the movement of the seat member 3 shown in the figures between his in the Fig. 1 . 5 and 9 shown first position and its in the Fig. 4 . 8th and 10 shown second position.

Fig. 1 shows the exemplary upholstered furniture 1 according to the invention in its first position. The effective area of the back element 4 is slightly inclined in a comparatively upright position and with respect to the vertical. The effective area 7 of the seat element 3 is in an approximately horizontal position, only slightly falling off to the rear. The angles of the effective surfaces 7 and 14 are preferably chosen so that there is a comfortable seating position.

If the drive 13 now moves the seat element 3 forward, then a lower guide counter element 15 moves forward in the lower guide element 5. The lower guide counter element 15 is rigidly received on the seat element 3. It is advantageously a leadership role. Such a guide roller is particularly well suited to pass through the bends of the lower guide element 5. At the same time, an upper guide counter element 16, which in the example shown is advantageously connected rigidly to the base element 2 in the front region of the base element 2, moves in the upper guide element 6 towards the rear, that is, toward the end facing the back of the upholstered furniture. The upper guide counter-element 16 is preferably a sliding element. Such sliding elements are particularly advantageous in combination with straight guide elements.

As in the Fig. 2 . 6 and 7 can be seen, the lower guide counter-element 15 moves in the lower guide member 5, initially slightly downward, while the seat member 3 moves forward. As a result, the rear region of the useful surface 7 is further lowered relative to the front region of the useful surface 7. At the same time the movement of the seat element 3 via the first link 8 and the second link 9 causes a movement of the back element 4. This moves first ( Fig. 6 ) also forward, in particular to prevent the back element 4 collides with a located behind the upholstered furniture 1 wall. As the movement progresses, the back element 4 begins to assume an increasingly shallower position ( Fig. 2 and 7 ).

In the further course of movement, by the transition of the Fig. 2 to Fig. 3 is shown, the lower guide counter-element 15 moves in the lower guide rail 5 upwards when it passes the two bends and the intermediate, rising forward regions of the guide member 5. This gives the movement of the seat member 3 a forwardly directed rotational component. The rear area of the effective area 7 of the seat element 3 rises relative to the front area of the usable area 7. As a result, the effective surface 7 approaches a horizontal position. At the same time, the support element 17, which is preferably held rigidly on the seat element 3, is lowered. The support member 17 is formed in the example shown in an advantageous manner as a support role. The position of the backrest continues to flatten in this part of the movement. In a comparison of the distance between the bottom surface 18 and the support member 17 in the Fig. 2 . 3 and 4 It is clear how the support member 17 approaches the bottom surface 18, while the lower guide counter-element 15 passes through the S-shaped curved portion of the lower guide member. Fig. 3 shows the position of the lower guide member 17 immediately prior to placement on the bottom surface 18th

In the last section of the movement in the in the Fig. 4 . 8th and 10 shown second position, the seat member 3 moves a relatively short distance. The support member 17 moves in this way preferably in contact with the bottom surface 18. In this in the Fig. 3 and 4 shown portion of the movement moves in the example shown above all the lowering back element 4. If the in the Fig. 4 . 8th and 10 shown second position is reached, the effective area 14 of the back element 4 has reached an approximately horizontal position. When comparing the movement paths of the seat element 3 and back element 4 over the Fig. 1 to 4 It is clear that the back element 4 in the in the Fig. 3 and 4 Part movement shown covers a comparatively large part of the rotational component of its total movement, while the seat element 3 covers only a very small path area.

This kinematics, which results from constructive and user requirements, has on the last piece of the movement a disadvantage. Looking at the declining movement of the Fig. 3 to Fig. 4 , so the drive with a small path of movement, which can be measured on the path of movement of the seat member 3, lift the back member 4 from its horizontal position. This results in comparatively unfavorable leverage. It may therefore be advantageous to provide a support element-not shown in the figures-which exerts an additional force on the back element 4 on the first part of this path. This may be, for example, a spring which is arranged between the base element 2 and the first link 8 and in particular spans on the last portion of the path of the back element 4 in the second position.

The FIG. 12 shows the side view of another embodiment of the upholstered furniture according to the invention 1. The upholstered furniture is in the position 1, the sitting position. The back element 4 stands upright and the seat element 3 is slightly lowered toward the back element 4. The guide element 5 is arranged on the base element 2. In the guide member 5, the lower guide counter-elements 15, 26 (not shown here) are arranged. On the guide member 5 is the third lower guide counter-element 27. The guide counter-elements 15, 26, 27 are arranged on the connecting element 28, which is in this position almost parallel to the guide member 5 and is movably coupled to the portion 25. The portion 25 is further arranged on the rear part of the seat member 3. The upper guide element 6 is likewise arranged on the seat element 3. During the movement from the sitting position to the lying position, the guide element 6 moves along the guide counter-element 16, which is firmly connected to the base element.

At the right end of the lower guide member 5, a recess 30 is mounted, whose function in the Fig. 13 is described. To the left of the recess 30, a guide aid 29 is arranged.

Now, if the seat member 3 is pulled to the right or pushed by a motor drive, so move the lower guide counter-elements 15, 26, 27 in or on the lower guide member 5 to the right and the upper guide member 6 moves to the upper guide counter-element 16 also after right until the lower guide counter element 15 abuts the right end of the lower guide element 5. The fact that the back element 4 is coupled at the bottom to the seat element 3, the lower end of the back element 4 also moves to the right, so that the back element 4 is moved from an upright position (FIG. Fig. 12 ) in a horizontal position ( Fig. 14 ) is transferred.

The FIG. 13 shows the upholstered furniture 1 shortly after the stop of the guide counter-element 15 to the right end of the lower guide member 5. The lower guide counter-element 15 can no longer follow the movement of the seat member 3. The arranged on the rear part of the seat member 3 section 25 now pulls on the connecting element 28 so that it rotates about the lower guide counter-element 15. When the lower guide counter element 15 abuts against the end of the guide element 5, the second lower guide counter element 26 comes to lie below the recess 30. When now starting rotational movement about the lower guide counter-element 15, the second lower guide counter-element 26 is lifted by the recess 30 and guided along the guide aid 29. The third lower guide counter element 27 lifts off from the guide element 5.

By this rotational movement of the portion 25 and thus the rear part of the seat member 3 is lifted by the connecting element 28 and thereby rotated about the fixed upper guide counter-element 16. This rotation causes the support member 17 located at the front end of the seat member 3 to lower. In this embodiment, the footrest member 10 has also been extended.

The FIG. 14 shows the upholstered furniture 1 in position 2, the lying position. When the left end of the upper guide member 6 abuts against the fixed upper guide counter member 16, the extension movement, the movement from the position 1 to the position 2, is completed and the support member 17 is located on the bottom surface 18. In the embodiment shown here has the coupling point between the connecting element 28 and the section 25 moves slightly beyond the zenith of the rotary movement, which leads to a greater stability of the upholstered furniture 1 in the position 2. The effective area 14 of the back element 4, the effective area 7 of the seat element 3 and the useful area 19 of the foot support element 10 lie in one plane and thus form a good lying surface.

If the seat element 3 is moved to the left from this position, then the guide element 29, against which the second lower guide element 26 abuts, prevents the lower guide counter element 15 from also moving to the left. Thus, first, the rotational movement is initiated until the second lower guide counter-element 26 is completely immersed in the lower guide element 5 through the recess 30. The resting on the lower guide member 5 third lower guide counter-element 27 prevents with the two other lower guide counter-elements 15, 26 a further rotation, so that then the translational movement along the lower guide member 5 is initiated.

Is the upholstered furniture 1 from position 1 ( Fig. 12 ) to position 2 ( Fig. 14 ), so passes through the portion 25 and thus the rear part of the seat member an approximately S-shaped movement, which causes initially the support member 17 is raised and placed in the last movement section on the bottom surface 18.
