The invention relates to a row chair with a seat that is foldable and hinged at the rear end, the backrest and preferably the two armrests, which supports the frame is attached to a carrier.

In a known row chair, the frame consists of a heavy casting, which with a hollow Recording is intended for a specially shaped pin of the single leg associated with the frame. the known row chairs are heavy and complex in construction.

It is also a row of chairs with foldable ones arranged on a continuous underframe Individual seats known, with each seat and the associated backrest formed as a single single frame which is releasably attached to continuous rails of the base. The chair frames exist here from three individual parts, namely the backrest, the seat and the armrest. Such row armchairs are only in place on the traversed assemble the base.

The invention has for its object to provide a row chair of the type mentioned above, which simple in construction and can be connected to any supporting frame in the simplest possible way.

The object is achieved according to the invention in that the frame consists of two L-shaped supports for receiving the backrest plate and the There is a hinge, one part of which firmly connects the two parallel legs of the supports, while the seat plate is attached to the other hinge part.

The frame according to the invention forms a light and easy to manufacture unit, which not only can be connected to monopod supports, but also to continuous underframes.

The supports consist in a known manner of profile steel, preferably steel pipe.

The upwardly directed legs of the supports are expediently diverging upwards educated. This offers the possibility of the supports with their upper end on the side of the backrest Execute bent over to the front and their ends as armrests or carriers for the armrests use.

In the known type of construction of the seat frames on a continuous, common carrier, the Racks are arranged obliquely to the longitudinal direction of this carrier, whereby with a given aisle width a larger space for the legs of the user is achieved.

To achieve the same angle of view on the stage or the like. The inclination of the individual Seat frames are carried out on the carrier so that

it increases steadily starting in the middle of the row towards the ends.

The subject matter of the invention is illustrated in the drawing, for example, and is described in detail below with reference to the drawing.

Fig. 1 shows a side view of the chair according to the invention;

Fig. 2 is a rear view;

3 shows a partial side view on an enlarged scale;

Fig. 4 shows the hinge from the front.

As can be seen from FIG. 1, the seat frame according to the invention consists of the seat _1, the hinge 2, the two L-shaped supports 3 and the backrest 4. The hinge is designed as a simple folding hinge with two plate-shaped hinge legs 5, 6. Of these hinge legs, one (5) is attached to the underside of the seat 1 in such a way that the hinge point 7 lies on the rear edge of the seat. The seat 1 itself consists in a manner known per se of a pre-pressed wooden plate, preferably with a rounded rear edge, to which, for example, a foam rubber pad can be applied, which is covered with a plastic or the like.

The two tubes 3 for the backrest 4 engage the lower horizontally lying hinge leg 6. The lower end of these tubes is horizontal guided forward and on the underside of the lower hinge leg 6, for example with the help of Screws 8 attached. The tubes are on the back of the backrest V-shaped upwards and to the sides the backrest passed to the front. They end in the horizontal upper section on which the armrest boards 9 are attached.

As can be seen from Fig. 3, the lower hinge leg 6 carries at its front end in the form of a Rubber plate 10 is a known buffer for the seat, the impact when folding down

dampens. The lower hinge plate is extended to the rear beyond the joint. The upper hinge leg itself has stops in the joint that allow the seat to move upwards :; limit. In order to have damping here as well, a rubber damping 12, preferably in the form of a plate, is also provided between these stops and the mentioned extension of the lower hinge leg. The hinge pin protrudes laterally over the hinge. On these protruding ends, helical torsion springs are arranged, which usually hold the seat in the upright position. Of these springs, one leg engages the fixed chair part and the other leg engages the seat. The frame described so far forms a unit that can be attached to any carrier. In the drawing, a single tubular leg 15 is shown as a carrier, which is screwed to the bottom with a plate 16 on the floor. Another possibility is to place the frame in a manner known per se on a carrier extending in the longitudinal direction of the row of seats. It would also be conceivable to place the frame directly on a step without a carrier. Finally, the frame could also be placed on a horizontal support that is held in a wall or the like.
