Armchair for seating rooms, in particular conference, cinema, theater and concert rooms.

It is well known that armchairs are used when seating rooms, in particular conference, cinema, theater and concert rooms arranged in rows with each armchair attached to the floor. These armchairs exist usually made up of two side frames that are connected to one another by a backrest construction. Between the two Side frames are provided seat devices, which are folded around a horizontal transverse axis between a Position that ensures free passage between the rows of seats, and a position of use can be pivoted are. In some cases, armchairs are also used, in which two armchairs are combined into one unit in which the middle side frames are then omitted. These armchairs are then only worn from the external side frames.

In the style of rooms of this kind, then various problems arise. In rooms such as cinema, theater, concert rooms, etc., the floor usually rises towards the rear of the room. In this case, the armchairs have to go from one row to the next

0098U / 0528

Row can be arranged at different inclinations, around to ensure their user an optimal view of the area of action of the 7th room, depending on the height of the row of armchairs. In the known seating arrangements, this is usually achieved in that the armchairs of the various Rows are attached to the floor using different wedge pads.

Seating arrangements for spaces of the type mentioned require stän- W-ended maintenance and control, because such seating arrangements according to experience of the users are very strained, so often repairs are required. For rooms of the type mentioned, it is therefore necessary that replacement armchairs must always be available in order to replace damaged ones. Since the known armchairs have a very complicated structure, and the individual parts cannot be exchanged, a relatively large inventory of spare parts is required for such rooms. In addition, the replacement of the individual parts of such armchairs is usually complicated, since the individual parts are often firmly connected to the other structural parts of such armchairs and are difficult to detach.

Purpose of the invention is now to eliminate the above disadvantages and to provide a chair for seating of rooms, especially for conference, cinema, theater and concert spaces available, the extremely simple in construction> is easily assembled and disassembled can be adjusted in a simple manner with regard to its position of the backrest and the folding seat and in which the backrest and the folding seat are interchangeable.

O098U / 0528

The inventive armchair for the seating of rooms, .In particular of conference, cinema, theater and concert rooms is characterized by the fact that it has one on the floor has to be fastened support with a base part and two side parts, in which a backrest and a folding seat, which are practically identical, in different positions of use relative to Support brackets are adjustable.

The fact that the backrest and the folding seat of the present armchair are practically identical, can they can be exchanged easily. This makes it possible to store spare parts for the seating of spaces to a minimum.

The fact that the backrest and the folding seat, moreover in different positions of use relative to the support can be brought, the set-up is also simplified Such armchairs are very important because of the adjustment by means of. Chocks can now be dispensed with when fastening the support to the floor. The armchairs can be fixed normally on the floor and can then easily be adjusted to the most suitable sitting position will.

A particularly simple way of assembling and disassembling an armchair of the present type is preferably obtained when the side parts of the backrest and the folding seat, which interact with the side parts of the support, Wear bearing pins which engage in fork-like recesses in the side parts of the support bracket. on complicated fastening devices can then be dispensed with. It is only useful to add the backrest to be attached to the support bracket by means of releasable bolts, whereby to ensure the adjustability of the

O098U / 0528

Backrest such bolts on the side parts of the support 'and / or on the side parts of the backrest in different Positions lying on a pitch circle around the bearing pin can be set.

In order to prevent the folding seat from loosening from the support bracket, it is useful if the fork-like recesses for the pivot pins of the folding seat are each narrowed by means of a hump on their receiving side and the pivot pins each have flattened areas. The entire arrangement is then made f expediently so that the folding seat may be attached to the support means only when removing the back rest and in a lying outside the normal range used folding position.

A particularly advantageous embodiment of the Lehnstuhles with regard to its adjustment of the backrest and of the folding seat part is then obtained, when the rear end of the folding seat in the G _# ebrauchsstellur2 ε.η rests a lower abutment surface of the backrest. The distance between the lower stop surface and the axis of the bearing journals of the backrest preferably varies over the length of the stop surface. This automatically changes the position of the folding seat relative to the support bracket when the backrest is adjusted. The lower stop surface of the backrest is preferably designed in such a way that the distance between the stop surface and the axis of the bearing pin against the rear of the armchair becomes smaller. Resetting the backrest then simultaneously causes the folding seat to tilt downwards on its front side.

Embodiments of the armchair according to the invention are described in more detail below with reference to the drawings, showing:

5 shows the armchair in vertical section through its backrest, its folding seat and the support; as

6 shows the armchair according to FIG. 5 with the folding seat folded down, in section along the line VI-VI, in Cutout.

As can be seen from Figures 1 to 5, the armchair consists of three elements: the support P, the backrest A 'and the folding seat A ¹ '. The backrest A 'and the folding seat A ¹ ' are essentially identical, so that they can easily be interchanged with one another. The individual components of the armchair are preferably made of plastic, with synthetic resin, preferably polyester resin, being used which is reinforced. The individual components of the armchair can thus be manufactured economically in the simplest way in large numbers.

The support P consists of a base part 10 and two side parts 11 and 12, which are arranged so that they give the .Tragstütze a substantially U-shaped shape. The base part 10 forms the base and the two side

0098U / 0528

tenteile 11 and 12, the legs of the U. The support is now through one of the side panels 11 and 12 and the base 10 connecting rib IjJ in the lower area of the support reinforced. This rib can be used to make cleaning easier 13 can also be partially recessed in the area of the Sookel. The support is further strengthened by a preferably on the back provided transverse web 14. The entire support, including the base part, side parts, The rib and crosspiece are preferably made in one piece from | Made of plastic. The attachment of the support and so that the armchair takes place on the base part 10, which is for this purpose by means of bolts, screws, nailing or the like is anchored to the floor.

The backrest A 'and the folding seat A ¹¹ are constructed practically identical and each have side parts 15 and

16, which are used for reinforcement and a central part

17 wear. These parts are also expediently

made in pieces from plastic of the type mentioned above. The backrest and the folding seat can preferably be in be upholstered and covered in a known manner.

The side parts 15 and 16 of the backrest or the folding seat are equipped on their outside with bearing pins 18 which are used ^{to fasten the backrest A 1} and the folding seat A ″ to the support P. For this purpose, recesses are provided in the latter, for example

Holes in the side parts 11 and 12 of the support bracket, may be. However, it is particularly expedient to provide fork-like recesses 19 , 20 and 2J> . The fork-like recesses 19 and 20 intended for receiving the bearing journals 18 of the backrest A ¹ are provided at the upper end of the side parts 11 and 12, specifically on their parts facing the rear, so that the back

ί 0098U / 0528

backrest inserted from above into the fork-like recesses can be. The actual assembly of the armchair and thus the attachment of the backrest A 'is described below described in more detail.

As can be seen in particular from FIGS. 4 and 5, the fork-like recesses 23 for receiving the bearing journals 18 of the folding seat A ′ ^{1 are provided} on the front side of the side parts 11 and 12. As can be seen from FIG. 3, the fork-like recesses 2j5 are arranged in such a way that they enable the inserted folding seat to tilt about the axis RH from the unfolded position into the position of use.

As FIGS. 4 and 5 now show, the fork-like recesses 25 for the bearing pins 18 of the folding seat A ^{11 are} each narrowed by means of a hump 23 ″ on their receiving side. The bearing journals 1 × 8 in turn each have a flattened area 18 ′, through which the bearing journal 18 has a tapered area which enables it to be guided past the hump 2J ″ of the recess 23. The. The entire arrangement is now such that the folding seat A ¹ 'can only be attached to the support P ^{with the backrest A 1} removed and in an operating position outside the normal folding area B ¹ to B ^11. The inner part of the recess 23 'is shaped so that the pin 18 can rotate freely therein about the axis RR.

The armchair is now assembled in such a way that the folding seat A ¹ 'is first inclined so far forward that the pin 18 can be inserted into the fork-like recess over its area tapered by the flattening 18' past the hump 23 ". The inclination of the folding seat A ' ¹ is such that its rear end in the loading'

rich device, which was normally filled by this when the backrest was mounted. After the folding seat A ^M has been inserted, it is pivoted into its unfolded position B ″. The backrest A ^{1 is then} attached by inserting it into the fork-like recesses 19 and 20 by means of its pegs 18. To further fix the backrest A ¹ , various openings 25 are provided in the side parts 15 and 16 of the backrest and / or in the side parts 11 and 12 of the support P, each arranged on a pitch circle concentric to the bearing pin 18. These openings 25 are used to accommodate removable locking bolts that ^{hold the backrest A 1} in the position selected once. The backrest itself can be adjusted according to the number and arrangement of the openings 25.

As can be seen most clearly from FIG. 5, the pivoting range B ¹ to B ^{11 of} the folding seat A ^{TI is} determined by the following stops. In the position of use B 'the folding seat A ^{11 rests} with rear surfaces 15 ¹ and ^{16 1 of} the side parts 15 and 16 on lower stop ^{surfaces 15 ″ and 16 ′ f of} the side parts 15 and 16 of the backrest A ¹ . In the unfolded position B ″, on the other hand, the rear end of the folding seat rests against a stop 24 formed by the rib 13. For the purpose of noise damping, this stop 24 can optionally be provided with padding made of rubber or the like.

In order to simultaneously effect an adjustment of the seat inclination of the folding seat A ¹ 'when the backrest A ^{1 is} adjusted, the backrest and the folding seat are preferably further configured as follows. The stop surfaces I5 ¹ 'and I6 ^{1 f} * of the side parts 15 and 16 of the back tendons A ^f have a

Distance from the bearing pin 18 of the backrest, which varies along the stop surfaces. The stop surfaces are preferably designed in such a way that their distance from the bearing pins l8 to the rear of the armchair becomes smaller. If, as shown in FIG. 5, the backrest is moved in the direction of C 'or C'', the tilt of the folding seat changes simultaneously in the direction of D ¹ or D ^tT , that is, if the backrest is in a flatter position, the The tilt of the folding seat is flatter. This results in the very decisive advantage that only one and the same armchair can be used for any seating arrangement, and when it is finally set up in a room, it can be easily adjusted to the optimal seating position in relation to the area of activity of the room. The customary manufacture of special armchairs for the individual rows of seats for conference, cinema, theater and concert rooms is no longer necessary. It is also no longer necessary that. To bring armchairs in place by placing wedges of various thicknesses under the appropriate seating position.

The armchairs can, as can be seen, for example, from Fig. 6, be set up with a small mutual spacing, where they can form both straight and curved rows. At the upper ends 21 and 22 of adjacent armchairs armrests can be attached.

The present armchair is thus characterized by an extremely simple structure, which not only enables the armchair to be manufactured very economically, but also, above all, considerably simplifies its assembly. At the same time, it offers the possibility of its backrest and its folding seat in the simplest way to any viewing position without additional auxiliary
