DE 43 22 337 discloses a piece of seating furniture of the type mentioned above, in which both the base body and the backrest part each have a fitting. This fitting, which is arranged on both the base body and the backrest part, has a tube, whereby the tube of the backrest fitting and the tube of the seating furniture fitting are rotatably mounted inside each other. The tubular connection serves both to fix the two parts together and as a guide for the rotation of the two parts relative to each other. Both the backrest part and the base body of the seating furniture have a slope in the area of their contact surfaces on both sides such that in one position of the backrest part the backrest part points upwards, i.e. can perform its function as a backrest, and in another case the backrest part extends parallel to the sitting or lying surface of the sofa or the base body, so that a lying surface is created. In the seating or reclining furniture known from DE 43 22 337, not only is the side rest detachably connected to the base body of the seating or reclining furniture, but also the backrest using the same technology.

Furthermore, DE 198 01 358 discloses a piece of seating or reclining furniture in which the side rest is arranged on the base body of the seating or reclining furniture using a similar technique as in the previously discussed DE 43 22 337. Here, too, two fittings are provided on the base body of the seating or reclining furniture and the backrest, which enable the backrest to be rotated relative to the base body of the seating furniture and to be locked to the base body.

The disadvantage of the current state of the art is that the fittings are relatively complex and the seating or reclining furniture becomes very expensive as a result. This means that such constructions are only suitable for seating or reclining furniture in the high-priced market segment.

The invention is therefore based on the object of creating a seating or reclining furniture of the type mentioned at the beginning, which is simpler and cheaper to manufacture, but nevertheless enables the seating or reclining furniture to be transformed from a seating furniture to a reclining furniture and vice versa in the same way as in the prior art.

The object is achieved according to the invention in that the backrest part can be connected to the base body by at least one sliding guide. Such a sliding guide, for example designed as a dovetail or fold and groove guide, enables the backrest part to be pulled out sideways from the base body, the backrest part to be rotated when removed and the backrest part to be pushed onto the base body of the seating or reclining furniture in the opposite direction. The advantage of a sliding guide - and here in particular a dovetail or fold and groove guide - is that it is very easy to manufacture. This is particularly true when such guides are made of wood, whereby only appropriately designed strips have to be arranged at a suitable location on the backrest part or base body of the seating or reclining furniture. The advantage of such sliding guides is that a relatively large area is available to absorb forces, so that such seating or reclining furniture is extremely stable. Another advantage here is that there is no need for metal fittings, which have to be purchased separately by the furniture manufacturers. The previously described wooden sliding guides, however, can be provided by the upholstered furniture manufacturers themselves. The use of metal would have the advantage of making the guide slimmer.

According to a further feature of the invention, it is provided that the backrest part can be locked to the base body, for example by the base body or the backrest part each having a stop at the end of the sliding guide.

A stop is the simplest possible way of fixing and thus enables easy handling when transforming the furniture by moving the backrest. The armrests can be attached alternately - from right to left and vice versa - or can be inserted from front to back or from back to front.

Furthermore, when the furniture is set up, the sliding guide can be arranged horizontally, vertically or at an angle on the furniture. Such a different arrangement of the sliding guides also depends essentially on the desired design. With horizontal or vertical sliding guides, the backrests will be vertical, whereas angled guides allow the backrests on the seating or reclining furniture to be arranged at an angle. In particular with angled sliding guides, both the sliding guide on the base body and a sliding guide on the backrest part are each designed as an inclined plane, in particular at an angle of 30° - 45°.

The invention is explained in more detail below with reference to the drawing:

Figure 1 shows a sofa with a detachable armrest, whereby the sliding guide is arranged as an inclined plane both on the base body and on the backrest of the sofa.

Figure 3 shows an embodiment in which the backrest of a

Sofas can be connected to the base body of the sofa by means of a sliding guide;

Figure 4 shows a dovetail guide;

Figure 5 shows a folding and groove guide;

Figure 6 shows a view of the sliding guide, with the bar

can be recognized as an attack.

The sofa, designated as a whole with 1, consists of a base body 10 with two armrests 11 and two backrests 12. The base body 10 of the seating or reclining furniture is in the form of a seating or reclining surface. The armrests 11 are connected to the base body by a sliding guide 20 (see Figure 4 and Figure 5). In the arrangement of the armrests according to Figure 1, both the armrest and the base body each have an inclined plane, the plane being selected such that in one position of the armrest 11 it can actually serve as an armrest in that it points diagonally upwards, whereas in the second position the surface of the armrest forms a plane with the seating or reclining surface. This means that the inclined plane has an angle of approximately 30° - 45°.

In the design according to Figure 2, the base body of the sofa is designated 30, the armrests each have the reference number 31 and the backrests have the reference number 33. In this design of a piece of seating or reclining furniture, two guides 41, 42 are provided, which are arranged at right angles to each other on the base body 30. This type of fastening of the backrest part 31 to the base body 30 has the advantage of increased stability, because two such sliding guides are provided, which can absorb the corresponding forces.

Another embodiment of a piece of seating or reclining furniture is shown in Figure 3 in that the base body 50 of the seating or reclining furniture has a backrest 51 that is adjustably arranged on the base body 50. The sliding guide 52 runs in the form of an inclined plane on the base body 50 and parallel to the longitudinal axis of the base body 50. A support 60 is provided to support the backrest part, which gives the structure the necessary stability. The backrest part is locked in place by the additional backrest that is at an angle to it, i.e. the backrest or armrest.

However, it is also conceivable to arrange a bar 90 on the backrest in the area of the sliding guide using several screws 91. This bar 90 acts as a stop when the backrest is pushed into the guide of the base body (Figure 6). Conversely, the stop can also be arranged on the base body. However, the bar 90 not only serves to lock or fix the backrest to the base body of the sofa, but also as a screen for the gap between the armrest and the base body, which is caused by the thickness of the sliding guide. However, the bar 90 means that when changing the armrest, it is necessary to move it from one side of the sofa to the other and vice versa. Otherwise the bar would be in the way.

Figures 4 and 5 show a cross-section of a dovetail or a fold and groove guide. In the dovetail guide according to Figure 4, the guide has the reference number 70 and the dovetail guided through the guide has the reference number 71. In the groove and fold guide according to Figure 5, the groove guide is designated with 80 and the guide member with 81.
