  • a seating device usually consists of a seating surface which is arranged horizontally either on feet or on a base at a height adapted to a person's sitting posture.
  • a backrest is also provided on the back of the seat device, which forms an approximately right angle with the seat surface.
  • the depth of the seat ie the distance between the front edge of the seat and the backrest, corresponds approximately to the length of a person's thigh.
  • Armrests are often arranged on one side of the seat device or on both sides of the seat device in order to also provide lateral support for the person sitting on the seat device and to provide a support surface for the arms.
  • seating devices are designed, for example, as a chair, armchair, sofa or stool in different materials and different designs.
  • Lying devices essentially consist of a lying surface that allows sufficient space for a person lying on the lying surface. Accordingly, the bed surface generally has a greater depth than the seat surfaces.
  • the lying surface is usually arranged on one or more feet or a base.
  • Combined sitting and lying devices usually consist of a lying surface, whereby for use as a sitting device, cushions can be arranged on one long side of the lying surface and often also on both end faces, which then fulfill the function of a backrest and armrests.
  • the pillows are often loosely grouped on the lying surface so that they can easily slip.
  • the pillows must be removed.
  • the problem here is that the pillows have to be stowed somewhere.
  • the pillows are placed next to the lying device, which on the one hand adjusts the floor area and on the other hand creates an uncluttered impression of the room concerned.
  • the object of the invention is therefore a sitting and / or lying device
  • the seat surface is easily adjustable in depth, with no parts the sitting and / or lying device must be removed.
  • a seat and / or Lying device equipped with a seat or lying surface and a backrest, wherein the backrest by means of at least one swivel joint from a front Position can be pivoted to a rear position.
  • the backrest In the front position the backrest preferably overlaps a part of the seat or lying surface, whereby the effective usable area of the seating or lying area is reduced.
  • the backrest closes in the rear position In the top view, it expediently points directly to the seating or lying surface only a small overlap area with the seat. This will achieved that when using the seat and / or lying device as a lying device the entire or almost the entire seating or lying area as an effective usable area is available.
  • the sitting and / or lying device designed according to the invention can thus advantageous both as a seat device with a usual for a seat device Usable area or seat depth or as a seat device with an enlarged usable area can also be used as a lying device with an enlarged usable area.
  • a seat device with a usual for a seat device Usable area or seat depth or as a seat device with an enlarged usable area can also be used as a lying device with an enlarged usable area.

  • the seat or lying surface advantageously has a depth of 0.85 m to 1 m, preferably a depth of 0.9 to 0.95 m, and the backrest in the depth direction of the seat or lying surface preferably has a width of 0. 35 m to 0.45 m, particularly preferably from 0.4 m.
  • the connection can be made indirectly or directly, ie the swivel joint can be attached directly to the seat or lying surface on one side or it can also be connected to the seat or lying surface via one or more intermediate elements.
  • the armrest also expediently by means of a Swivel joint swiveling from a front position to a rear position is. It is advisable to fix the backrest and the armrest together connect to. This ensures that the backrest and armrest always in a fixed position to each other during and after the swiveling process are arranged. It is also used to swivel the back and armrests only an executing handle or a sequence is required. A Reduction in the number of steps to be taken for an activity is particularly important for Objects of everyday use, such as furniture, of great size and the benefit highly valued by the respective user. In addition, by the fixed relative arrangement of the backrest in relation to the armrest the overall aesthetic impression of the furniture is preserved in all swiveling phases.
  • the swivel joint can be stepless both in the front and in the rear as well as in any Lock the intermediate position. In another preferred embodiment it can only be locked in the front and rear positions.
  • the seating and / or lying device according to the invention can expediently be designed as an armchair.
  • the dimensions correspond largely to the dimensions of standard armchairs.
  • the seating and / or reclining device according to the invention can also be designed as a two- or multi-seater. Two-seaters and multi-seaters are often preferably equipped with a backrest and only one armrest, in particular for the purpose of combination with a stool.
  • a side table is also expediently provided with the sitting and / or lying device.
  • the side table essentially consists of a table top and one or more supporting elements that support the table top, usually one foot or several feet. The side table can preferably be moved by means of rollers attached to the supporting elements of the table.
  • the support element or the support elements in such a way that they allow free access to the area below the table top from at least one side.
  • the sitting and / or lying device can be made of anything for such objects usual materials.
  • the inventive design of the seat and / or lying device is especially for those with a high Weight designed seating and / or lying devices suitable, for example Seat devices made of marble or stone.
  • FIG. 1 shows a top view of a first embodiment according to the invention of a sitting and / or lying device 1 designed as a two-seater.
  • the sitting and / or lying device 1 essentially comprises a sitting or lying surface 2 as well as a backrest 3 and an armrest 4.
  • a frame 5 is expediently arranged below the seat or lying surface 2.
  • the backrest 3 and the armrest 4 are arranged at a right angle to one another and are rigidly connected to one another.
  • the top view does not show the arrangement of the backrest 3 or armrest 4 in the height direction relative to the seat or lying surface 2, ie perpendicular to the plane of the drawing.
  • the backrest 3 or armrest 4 is expediently arranged in relation to the sitting or lying surface 2 from an anatomical point of view. It is both possible to have the backrest 3 connected directly to the seat surface 2 or to space the seat or lying surface 2 and the backrest 3 from one another, so that a gap remains between the seat or lying surface 2 and the backrest 3 .
  • the backrest 3 and the armrest 4 are arranged in a front position relative to the seat or lying surface 2, the area of the backrest 3, as can be clearly seen in the plan view, or lying surface 2 overlaps. Because of the overlap, the area of the seat or lying surface 2 that can be used for sitting or lying down is reduced by the overlap area.
  • the depth of the seat or lying surface 2 is chosen so that the seat or lying surface 2 reduced by the overlap area satisfies the anatomical requirements of a person, ie that an average adult finds sufficient seating space to be able to assume a comfortable sitting position.
  • the seat or reclining device 1 shown in FIG. 1 is primarily designed as a two-seat seat device with a seat surface width of 138 cm.
  • the armrest 4 and also the backrest 3 are designed with a width of approximately 35-40 cm.
  • frame feet 6 of the frame 5 arranged below the seat and lying surface 2 are shown schematically in FIG. The circles entered in the area of the backrest in FIG. 1 and the circle drawn in on the left in FIG.
  • connection points of the swivel joints to the backrests 3, 4 are not shown here. However, these connection points, not shown, of the swivel joints to the backrests are arranged offset to the connection points of the frame, all connection points being offset by the same distance.
  • connection points of the swivel joints to the backrests would each be arranged below the articulation points 6a, 6b, 6c of the frame, that is to say the connection points of the swivel joints in question to the backrest have a smaller distance from the center of the seat surface than the two upper articulation points 6a, 6b of the Frame.
  • the swivel joints are designed here so that they enable a swivel movement of at least 180 ° around the articulation points 6a, 6b, 6c.
  • the connection points of the swivel joints to the arm and backrest thus describe a semicircular path in the case of swiveling.
  • connection points of the swivel joints to the backrest are pivoted outwards, ie the connection points to the backrest are at a greater distance from the center of the seat surface 2 than the two upper articulation points 6a, 6b of the swivel joints.
  • Freewheels integrated into the swivel joints enable the backrests to remain fixed in their orientation even during swiveling and not to rotate in accordance with the change in position of the connection point.
  • the backrest and the armrest accordingly only perform the pivoting movement during a pivoting process, but this leads to a change in position of the backrests 3, 4 relative to the seat surface 2.
  • the backrest 3 and the armrest 4 can be brought into a rear position by means of a 180 ° pivoting process.
  • at least one of the swivel joints can be locked both in the front and in the rear position, so that the swiveling process cannot be initiated unintentionally.
  • the backrests 3, 4 can only be pivoted after the locking mechanism has been released. In the rear position, the overlap of the backrest 3 and the seat surface 2 is at least reduced or completely eliminated compared to the front position of the backrest and armrest shown in FIG. 1.
  • the effective usable area of the seat surface 2 can be enlarged, the seat surface 2 being substantially increased in depth.
  • the depth of the seat is sufficient to provide sufficient space for a person, so that sitting is also possible with feet tightened and placed on the seat.
  • Other applications of the seat device shown in FIG. 1 with the backrest arranged in the rear position are also conceivable, such as, for example, use as a cot with a lying surface sufficient for children. Due to the small width of the two-seater, it can only be used to a limited extent for adults. However, it is easily possible to provide a stool 8, as shown for example in FIG. 3, and thus to obtain a full lying surface.
  • the backrests of the sitting and / or lying devices are partially designed with a width that differs from the width of the seat surface.
  • the backrest 3 from FIG. 1 has, for example, a smaller width than the seat surface 2.
  • this further sitting and / or lying device can therefore not have a backrest or a backrest with a smaller width than the width of the seat in question or also have a backrest projecting beyond the seat.
  • the backrests of the seat and / or lying devices to be combined in each case preferably complement one another in accordance with a modular principle, so that a closed backrest is formed along the entire seat surface after the elements have been put together.
  • FIGS. 2 and 4 to 17 each show a top view of further embodiments and in particular also various combinations and combinations, which are designed according to the same principle as described above.
  • FIG. 2 shows a single-seat armchair 1, the seat surface 2 of which can be changed from a front position to a rear position in accordance with the adjustment principle described above by pivoting the backrest 3.
  • FIG. 4 shows a combined arrangement consisting of a two-seater according to FIG. 1 and an armchair according to FIG. 3.
  • the backrests 3 and the armrests 4 are in the front position.
  • Figure 5 shows the combination of Figure 4, here the armrests 4 and backrests 3 are pivoted into the rear position.
  • the usable sitting and lying surface 2 also offers a full person enough space to allow comfortable lying.
  • FIG. 4 and 5 can thus be used both as a seating device, for example as a sofa, and also as a lying device, for example as a guest bed or also as a full-size bed, particularly in the case of cramped living space.
  • FIG. 6 shows a similar, combined arrangement of two individual elements. Instead of the single-seat armchair from Figures 4 and 5, however, a stool without arm and backrest was provided here, so that this results in an arrangement that is open on one side.
  • the dimensions shown, with a total width of 201 cm and a depth of 92 cm, whereby the backrest swung into the rear position overlaps the seat by 6 cm, are to be understood as preferred dimensions for Central Europe.
  • FIG. 7 shows a top view of the sitting and / or lying device from FIG. 2 designed as an armchair, the backrest 3 and the armrest 4 being arranged in a rear position. This increases the usable seating area 2.
  • the seating device according to the invention can thus be used as an armchair with a customary seating area size (FIG. 2) or as a short ottoman (FIG. 7).
