DETAILED DESCRIPTION

(8) FIG. 1 shows a first embodiment of a piece of seating furniture according to the invention. This piece of seating furniture 10 is designed as an armchair. The piece of seating furniture 10 has a base member 20, which has an essentially square upper side 22 that forms a seat surface 24, with the seat surface 24 being not covered by a backrest member 60.

(9) Referring to FIGS. 2 and 3, the backrest member 60 is shown connected to the base member 20. For this purpose, a backrest fitting 40 is provided centrally on a base plate 26 of the base member 20, to which furniture feet 28 are also attached. The backrest fitting 40 is also shown enlarged in FIG. 4. The fitting 40 has a mounting plate 50 which is attached to the base plate 26 and a distal attachment plate 42 fixed securely to the backrest member 60. Two joints 48, 46 are connected above the fastening plate 50. A vertical joint 48 enables a rotational movement about a vertical axis 2. Thus, a horizontal joint 46 provided above vertical joint 48 and all further parts of the backrest fitting 40 can thus be rotated about a vertical axis by the vertical joint 48. The horizontal joint 46 is a horizontally acting joint. By the horizontal joint 46, a guide member 44 follows the horizontal joint 46, which leads to the backrest member 60 or an inner stiff support 64 thereof covered by padding 62, being swivelled about a horizontal axis 4.

(10) FIG. 2 shows the state in which the backrest member 60 is swivelled by about 80° about the horizontal axis 4 in relation to a starting position shown in FIGS. 1 and 3.

(11) To be able to swivel the backrest member 60 together with the guide member 44, a slot structure 30 comprising slots 32 is provided in the base member 20. The illustrated slot structure 30 has two crossed slots in the example of FIGS. 1 to 3 and 5A to 5D, thus forming four individual slots 32A to 32D, which meet in a connection area 34. The connection area 34 is located directly above the joints 46, 48. This allows the user to choose freely to rotate the backrest member 60 about a vertical axis 2 and to choose in which of the individual slots 32A to 32D the guide member 44 is to be inserted, and where, as a result, the backrest member 60 is to be located.

(12) This is illustrated in FIGS. 5A to 5D. In the state shown in FIG. 5A, the backrest member 60 is arranged in a first position. The guide member 44 is not visible in this position, as the guide member 44 is completely accommodated in the slot 32A in the manner illustrated in FIG. 3.

(13) In order to change the configuration, the backrest member 60 together with the guide member 44 is swivelled up in the manner illustrated in FIG. 5B until a first portion 44A of the guide member 44 is vertically aligned and is located in the connection area 34 of the slot structure 30. Now the backrest member 60 together with the guide member 44 can be swivelled around the vertical axis in the manner illustrated in FIG. 5C by 90°. Then the backrest member 60 can be lowered again in the manner illustrated in FIG. 5D, whereby the guide member 44 is inserted into the single slot 32D. Once the condition of FIG. 5D is reached, the armchair can be used again. Due to the fact that the backrest member 60 is connected to the base plate 26 via the guide member 44, the piece of furniture is very stable. There is no danger of the backrest member 60 moving backwards when leaning against the backrest member 60.

(14) FIGS. 6 to 8B show alternative embodiments.

(15) In the construction according to FIG. 6, only three individual slots 32A, 32B, 320 are used instead of four individual slots. Accordingly, the backrest member 60 cannot take up four different positions, but only three different positions.

(16) In the design according to FIG. 7, the piece of seating furniture 10 is configured such that the base member 20 does not have a square upper side 22, but a rectangular one. However, the slot structure 30 is still identical to that of FIGS. 1 to 3, so the backrest member 60 can be moved between four positions. However, parts of the upper side 22 of furniture 10 are not accessible for the backrest member 60.

(17) FIGS. 8A and 8B show two configurations of another example of the invention. This design example is a sofa 10 which has a design corresponding to that of two connected armchairs as shown in FIGS. 1 to 3. In this design, the two backrest members 60 are each provided with a guide member 44, which are connected to base plates 26 below the connection areas 34 in the manner already described. The two backrest members 60 can thus be brought into different positions independently of each other. FIG. 8B illustrates this by moving one of the backrest members 60 from the position along the long side according to FIG. 8A to the short front side.
