for this purpose, the arm rests 19a and 19b are provided on the ends Front parts 10a and 10b hinged so that their hinges 20 are on the outside. By swiveling open the armrests 19a and 19b, the respective receptacles arranged in the front parts are accessible and it is thus possible to take out the writing surface 16 on the one hand and the headphones 15 on the other hand from the armrests assigned to a chair. The armrests can then be returned to their closed position so that a comfortable sitting posture can be achieved can be taken.

In the following, in conjunction with FIGS. 2 and 4 to 7, the structural details, in particular of the supporting structure explained in more detail. Each of the supporting frames is designed so that it is in the interior of a front part 10, 10a and 10b a Armrest 9, 9a, 9b is to be accommodated, which is fixed to this support frame. Of the appropriately trained, the front parts 10a, 10b of the end armrests 9a, 9b associated with supporting frames is only one shown in Figure 5 and labeled 21a.

Since, as stated, the supporting frames are designed in principle the same as one another, only the supporting frame is essentially used 21 is described in more detail below. This comprises a base part 22 which has a substantially T-shape in plan view and which is designed with a view to fastening to the beam 6. The web of the in plan view extends to this T-shaped base part vertically and thus extends, based on the row of seats, to the front, where he

that according to Figure 6 essentially only in that it is due to the omission of an arm of the foot ax in plan view has a substantially L-shape. The arm protruding from the web extends in each case against the arm that adjoins the end part Row of chairs or the only neighboring seat. Corresponding to the fact that a base part at the end also only one backrest can be assigned, this also has only one rod 24.

The base parts 22 are just like the base parts at the end, provided there is a foot part 1 in the area of the respective base part is connected to this by screwing. Figures 2 and 4 to 6 show that the base parts 22, 22a are central, d. H. in their longitudinal center line, each provided with a pair of bores 30, which on the part of the leg la des Foot part 1 holes 25 correspond. These are in the leg parts forming the lateral boundary of the support saddle 5 5a of the foot part 1 is provided. The bar 6 is thus braced in the corresponding support saddle via the base parts, the base parts being held at the same time via the screw connections used for bracing. There where none Foot parts are provided in the area of the respective armrest 9, there is a respective one between the hollow beam 4 and the beam 6 saddle-shaped coupling piece 28 arranged, as Figure 2 shows. This saddle-like coupling piece, which in the exemplary embodiment Is designed in an H-shape, forms a support saddle 27 corresponding to the support saddle 5 for the beam 6, analogous to the connection of the base parts with the foot part 1 are now bores 26 in the upright leg parts 28a of the coupling piece 28.

The latter position is the writing surface, starting from the position shown in Figure 4, initially together with the Arm 37 pivoted outwardly through 180 ° around pin 36, which is arranged at the upper end of a support 57 extending upward from support bracket 31. The pivot axis of the Pin 36 lies horizontally parallel to the hollow beam 4 or to the beam 6. When this outer pivot position is reached, so the plate 16 is pivoted about its hinges 38 relative to the arm 37 into the aforementioned writing position.

The writing tablet as such is known per se. In their present embodiment according to the invention, in which they have the Arm 37 is carried, but it can, which cannot be seen from the drawing, in a particularly simple manner to the power supply connected and provided with a shielded light source that illuminates the writing surface. The line connection preferably runs through the arm 37 to the im Bars 6 or 6 * arranged connections.

The end support frames 21a, 21b are simpler in their structure, since only the writing surface 16 or the housing 17 for the headphones and the control desk 18 are assigned to the armrest 9a or 9b. All supporting frames 21, 21a and 21b are but provided with a rear support 39 which protrudes upwards and which has a small support at its upper free end 39a which extends rearward and which is provided with a vertical bore. This is designed and arranged that a pin 41 can be inserted into it, which is provided on a support member 42, which protrudes backwards on the inside on that wall part 34 of the front part IO or 10a,

As can be seen from Figure 13, the mold plate 59 and the Closing part pivoted forward, as shown in dashed lines in FIG.

The arm 37 can now be pivoted outwards about the pin 68 over an angle of approximately 180 °, the writing plate 16 still remaining in a vertical position. This is then pivoted about the axis of the joints over an angle of approximately 90 °, and thereby brought into a position in front of the user. In view of the three-fold pivotability that is provided here, the size of the writing plate 16 can be increased significantly compared to the first embodiment, in which there are only two pivotabilities and the writing plate must therefore have a relatively strong, curved circumferential surface.

In the second embodiment, an embodiment is also provided in which the seat 8, in addition to the usual vertical pivotability, can also be adjusted forwards and backwards, specifically displaceable. For this purpose, the seat 8 is provided with an inner, U-shaped frame 71 which has guides 72 at the side. The pivot pins 43 are in the utmmmt embodiment formed in one piece with a U-shaped, rtidcvtlrtlgen U-frame, which at the same time forms a balance weight. The U-frame 73 extends with its Arias 74 forward and, these arms 74 at their mutually and the guides 72 facing sides further guides 75 to · With 76 and 77 are on the one hand to the frame 73 and the other associated part of the frame 71 and in the guided tours

of the other frame-engaging slider. It is thereby an adjustment of the frames 71 and 73 in the longitudinal direction of their arms against each other possible without them being able to pivot against each other, since the two guides in The longitudinal direction of the arms lie one behind the other and thus each form two support points lying one behind the other. The displacement paths are limited by the length of the guides and the stops assigned to them. From Figure 10 is the The rear end position of the seat 8 drawn in full lines can be seen, while FIG. 11, drawn in dashed lines, shows the shows the front end position.
