    Or in a table base and its rotatable bearing in the front leg allows the seating device to be folded under, for example, a table.
    According to an embodiment of the invention, the backrest is mounted in a first toothed roller and the leg arch is mounted in a second toothed roller and these toothed rollers engage each other.
    According to an embodiment of the invention, the front legs of the seating device comprise an inner tube beam and an outer tube beam which encloses said inner tube beam and which outer tube beam can be displaced along the inner tube beam.
    According to an embodiment of the invention, the toothed rollers are stored in the outer tube beam.
    According to an embodiment of the invention, the support plate is attached to the outer pipe beam.
    According to an embodiment of the invention, the seating device comprises a frame which is mounted on the support plate, the frame having a rear edge with an exact fit against the backrest in its folded-up position. This gives the backrest a high stability.
    According to an embodiment of the invention, the seating device comprises two support plates mounted on each side of the outer pipe beam.
    Another embodiment which is also covered by the invention comprises a table to which at least one seating device in accordance with any one of claims 1 to 7 is attached.
    Brief description of the drawing The seating device according to the invention will now be described in more detail by embodiments with reference to the drawing, where: Fig. 1 shows two floor plans of boats with loose seats in accordance with known technology.
    Fig. 2 shows a schematic perspective view of a seating device according to an embodiment of the invention; Fig. 3 shows a schematic perspective view of the rotatable coupling between the backrest and the rear leg; F ig. 4 shows a schematic perspective view of a detail of the rotatable coupling; Fig. 5-8 shows schematic side views of how the seating device is prepared for use Fig. 9 shows a side view of an alternative embodiment. Description of embodiments of the seating arrangement An embodiment of the seating device, shown in Fig. 2, comprises a double chair with two seats, which are retractable under the table. A curved rectangular pipe beam 8 is the central part of the invention and has its functions. It is stored in a base plate 9 for floor mounting or mounting in a table base and functions in its lower part as a front pair of legs for the chairs.
    The rear part consists of an outer tube beam 2 which partly allows an increase in the seat depth and partly contains the storage of the two toothed rollers as 1 which constitutes the mechanism for lowering the leg arch 4. The backrest 5 is mounted in the front roller and the leg frame 4 is mounted in the rear rolls. The function of this mechanism with the toothed rollers is also illustrated in Figures 3 and 4, where it is clear how the toothed rollers grip each other during the extension and lowering of the backrest and the leg arch, respectively. In the outer tube beam 2, support plates 3 for the seats are mounted and on these support plates 3, outer layers 6 for attaching the backrests 5 and the leg arches 4 are mounted. The final frame 7 for a seat cushion is also mounted on the support plates 3. The rear edge of the frame 7 is designed with an exact fit against the backrest 5. In this way, the backrest gets the stability needed.
    Figures 5-8 show how the seating device is prepared for use. First, the seating device is folded down, this is made possible by the storage of the pipe beam 8 in the bottom plate 9.
    Then the seat depth is adjusted by pulling the outer tube beam 2 to the desired horizontal position. In the next step, the backrest 5 is then folded up and when this is done, the leg arch 4 is folded out automatically thanks to the toothed rollers 1. To fold in the seats, the process is repeated in reverse order.
    Figure 9 shows an alternative embodiment with seats according to the invention on both sides of the table.
