Die an dem auf dem Stützpfosten 1 drehbar angeordneten Obertheil des Stuhles befindliche zweitheilige Kappe 3, 5 greift mit einem Innenflantsch 6 unter dem am oberen Pfostenende vorspringenden Ring 4 um den Pfostenhals 2 und ruht mit zwei gewindeartig aufsteigenden Flächen 28 auf ebensolchen an dem Stützpfosten ι vorspringenden Gegenflä'chen 27. Zwischen den auf einander liegenden Flächen 27 und 28 befinden sich Gleitrollen 7.Located on the rotatably mounted on the support post 1 upper part of the chair two-part cap 3, 5 engages with an inner flange 6 under the ring 4 protruding at the upper end of the post around the post neck 2 and rests with two thread-like ascending Surfaces 28 on the same counter surfaces 27 projecting on the support post. Sliding rollers 7 are located between the surfaces 27 and 28 lying on top of one another.

Der Sitz 13 ist vermittelst der Zapfen 15 an den Armen 12 drehbar angebracht, welche von den mit der Kappenhälfte 5 ein Stück bildenden Armen 9 nach rückwärts ausgehen. An den Enden der Arme 9 sind Stützen 9¹ vorhanden, welche oben die Armstützen 11 tragen.The seat 13 is rotatably mounted by means of the pin 15 on the arms 12, which extend backwards from the arms 9 which form one piece with the cap half 5. At the ends of the arms 9 there are supports 9 ¹ which carry the arm supports 11 at the top.

An den senkrechten Streben 10 der Stuhllehne 16 sind unten nach vorn reichende Vorsprünge 17 angebracht, die mit schrägen Schlitzen 19 (Fig. 2) versehen sind, in welche an den unteren Ecken des Sitzes befindliche Zapfen 18 greifen.On the vertical struts 10 of the chair back 16 are reaching down to the front Projections 17 attached, which are provided with inclined slots 19 (Fig. 2), in which Grab pins 18 located at the lower corners of the seat.

Der Stuhl ist in gebrauchsfertigem Zustande, d. h. mit heruntergeklapptem Sitz vermittelst des durch die Kappe 3, 5 und den Stützpfosten ι gehenden Stiftes 23 in der richtigen Stellung festgestellt. Der Bolzen 23 steht in gelenkiger Verbindung mit einem nach unten reichenden Arm 22 an der unteren Strebe 20 der Stuhllehne.The chair is in a ready-to-use condition, i. H. with the seat folded down the through the cap 3, 5 and the support post ι going pin 23 in the correct Position established. The bolt 23 is in an articulated connection with a downward reaching arm 22 on the lower strut 20 of the chair back.

Beim Aufklappen des Stuhles gleiten seine Zapfen 18 in den schrägen Schlitzen 1.9 aufwärts, wodurch die untere Strebe 20 der Stuhllehne so weit zurückgedrückt wird, dafs der Stift 23 aus dem Stützpfosten 1 heraus-When opening the chair, his slide Pin 18 in the inclined slots 1.9 upwards, whereby the lower strut 20 of the chair back is pushed back so far that the pin 23 out of the support post 1.

is pulled. The cap 3, 5 then slides down with its threaded surfaces 28 on the threaded mating surfaces on the support posts r. The upper part of the chair, the seat and the backrest rotate this to 90 ⁰ to the position FIG. 2.

The seat cannot be folded down in this chair position because the bolt 23 cannot penetrate the support post in this position. A blocking of the It is therefore not possible to have passages through folded-down seats made by rows of chairs. If, on the other hand, the chair has assumed the position of use (Fig. 1), the seat can again be folded down. The pegs 18 slide in the inclined slots 19 again downwards and thereby push the backrest forward at its lower end, so that then the pin 23 penetrates the associated hole in the support post 1.

The unfolded chairs give the exit in all directions, what is of the utmost importance in the event of panic in large crowds.

The seat of the chair is not in the middle plane, but supported laterally by the same, whereby the advantage is obtained that the passages are given a substantial width, in spite of the fact that the chairs are more ready for use Row are equally spaced.

The seat can be raised high enough to allow a person to pass in front of the chair to allow without thereby completely removing the bolt 23 from its hole. The bolt 23 is only fully pulled out when the seat is only a few centimeters away is removed backwards from its outermost position ..

The particular embodiment of the cap 3, 5 shown in Figs. 8 and 9 allows to make them in one piece by attaching the protruding ring 4 (Fig. 3) the upper end of the support post can be omitted. Limiting the rotation of the chair, which caused the ring 4 in the above-described arrangement, is in this case by the stop of a projection 25 located on the cap against one on the Support post located pin 26 achieved.
