Unter Berücksichtigung des genannten Standes der Technik liegt der Erfindung die Aufgabe zugrunde, ein verbessertes Bestuhlungssystem bereitzustellen, das einen höheren Sitzkomfort bietet, kostengünstig herzustellen und robust ist.Taking into account the state of the art mentioned is the object of the invention, an improved Seating system to provide a higher Seating comfort offers, inexpensive to manufacture and robust is.

Diese Aufgabe wird bei einem Bestuhlungssystem nach Anspruch 1 gelöst,This task is in a seating system according to claim 1 solved,

Durch das Schwenklager ist es möglich, den Sitz in eine Schwenkposition zu bringen, in der seine Orientierung, bezogen auf den Aktionsort, im wesentlichen mit der Beobachtungsrichtung des auf ihm sitzenden Besuchers übereinstimmt. Soweit der Sitz eine Rückenlehne aufweist, ist sie vorzugsweise an der Sitzfläche befestigt und gemeinsam mit dieser einstellbar.The swivel bearing makes it possible to fit the seat in a To bring swivel position in which its orientation, related to the place of action, essentially with the direction of observation of the visitor sitting on him agrees. As far as the seat has a backrest, is they are preferably attached to the seat and together adjustable with this.

Sitze mit einer zentralen Schwenklagerung, die sich jedoch nicht für die Zwecke der vorliegenden Erfindung eignen, sind für andere Anwendungszwecke, beispielsweise aus der US-Patentschrift 1,875,449, der DE-A-2109486 und der JP-07241220-A bekannt.Seats with a central swivel bearing, however, are not suitable for the purposes of the present invention, are made for other applications, for example U.S. Patent 1,875,449, DE-A-2109486 and JP-07241220-A known.

Die Erfindung ist insbesondere für an den Längsseiten eines Spielfeldes angeordnete Sitze vorteilhaft, da die Beobachtungsrichtung der Besucher bei Bühnen-orientierten Ereignissen erheblich von der bei Spielfeld-orientierten Ereignissen abweichen kann. Die Ausrichtung der Sitze erhöht gegenüber dem Stand der Technik den Sitzkomfort. Um beispielsweise in einem Stadion eine Bühnenaufführung anzuschauen, müssen die Besucher nicht mehr die Köpfe in die Richtung der Bühne drehen oder schräg auf ihren Sitzen sitzen, sondern können auf ausgerichteten Sitzen entspannt dem Geschehen folgen.The invention is particularly for on the long sides of a Playing field arranged seats advantageous because of the direction of observation the visitor at stage-oriented Events significantly different from that at field-oriented Events. The orientation of the seats increased compared to the state of the art comfort. Around for example, watching a stage performance in a stadium, visitors no longer have to put their heads in turn the direction of the stage or at an angle on their seats sit, but can relax in aligned seats follow the action.

Selbstverständlich müssen nicht sämtliche Sitzeinheiten eines Veranstaltungsortes mit einstellbaren Sitzen ausgerüstet sein. Um Kosten zu sparen, können vorzugsweise nur die Längsseiten der Tribüne oder Teile davon mit dem erfindungsgemäßen Bestuhlungssystem ausgestattet sein.Of course, not all seating units need to be of an event location equipped with adjustable seats his. To save costs, preferably only the long sides of the grandstand or parts thereof with the invention Seating system.

In einer bevorzugten Ausführung weist die Sitzhalterung eine Arretierungseinrichtung auf, um den Sitz in der jeweils günstigen Schwenkposition zu arretieren. Dies erhöht die Bequemlichkeit, da der Sitz die einmal gewählte Schwenkposition auch dann beibehält, wenn sich der Benutzer auf dem Sitz bewegt oder ihn kurzzeitig verläßt. Eine Arretierung ist außerdem für kleine Kinder günstig, die sich beim Sitzen nicht mit ihren Füßen auf dem Boden abstützen können.In a preferred embodiment, the seat holder has a locking device to the seat in each to lock favorable swivel position. This increases the convenience since the seat is the one chosen Maintains pivoting position even when the user is moved on the seat or left it briefly. A Locking is also beneficial for young children who do not rest your feet on the floor while sitting can.

Vorzugsweise können die Sitze von dem Benutzer selbst auf verschiedene Aktionsorte ausgerichtet werden. Es kann jedoch auch vorteilhaft sein, wenn die Arretierungseinrichtung derart ausgebildet ist, daß sie nur von autorisierten Personen betätigt werden kann. Auf diese Weise wird ein unnötiges, die Veranstaltung störendes Hin- und Herschwenken der Sitze unterbunden. Die Sitze werden vor Beginn der Veranstaltung von Veranstaltungspersonal so ausgerichtet, daß die Beobachtungsrichtung für die Besucher optimal ist.Preferably, the seats can be opened by the user himself different locations of action. However, it can also be advantageous if the locking device is designed in such a way that it is only authorized People can be operated. That way an unnecessary swinging back and forth disturbing the event of the seats prevented. The seats will be in before the event by event staff that the direction of observation for visitors is optimal.

Das Schwenklager ist bei der Benutzung der Sitzeinheit hohen Belastungen durch schwergewichtige Benutzer und die vor allem bei Sitzen mit Rückenlehnen auftretenden hohen Kippmomente ausgesetzt. Vorzugsweise sind die Bauelemente für die Radiallagerung und für die Axiallagerung des Schwenklagers räumlich voneinander getrennt. Um die Stabilität des Schwenklagers zu erhöhen, ist die Axiallagerung in einer bevorzugten Ausführung als achsfernes Drucklastlager ausgebildet. Es weist ein sitzseitiges, die Schwenkachse in radialem Abstand umgebendes Lagerteil und ein in entsprechendem radialen Abstand angeordnetes, tribünenseitiges Lagerteil auf.The swivel bearing is when using the seat unit heavy loads from heavy users and the particularly high in seats with backrests Tipping moments exposed. The components are preferably for the radial bearing and for the axial bearing of the Pivot bearing spatially separated. For stability of the swivel bearing is the axial bearing in a preferred embodiment as remote from the axis Pressure load bearing designed. It has a seat-side, the bearing part surrounding the pivot axis at a radial distance and a corresponding radial distance, on the tribune-side bearing part.

To the seating system according to the invention to mount on such seat steps can have the seat brackets 15 in the axial direction a low height h, which is preferably less than 30 cm, preferably less than 20 cm. To this Way, it is possible to go through conventional seat seats Seat units 1 of the seating system according to the invention to replace.

Die Bauhöhe h der Sitzhalterung 15 kann in Abhängigkeit von der gegebenen Tribünenkonstruktion variieren. Bei Tribünenkonstruktionen, die für Sitzeinheiten mit größerer Bauhöhe ausgebildet sind, kann sie eine entsprechende größere Bauhöhe h haben und beispielsweise konisch oder säulenartig geformt sein.The height h of the seat bracket 15 can be dependent vary from the given grandstand construction. at Grandstand constructions for seating units with larger Height are designed, it can be a corresponding have greater height h and, for example, conical or be shaped like a column.

Eine erste Ausführungsform einer Sitzhalterung 15 und ihres Schwenklagers 16 sind in den Figuren 3 und 4 im Detail zu erkennen. Die Sitzhalterung 15 weist tribünenseitig eine auf der horizontalen Stufenfläche 11a der Tribüne befestigte, ortsfeste Halteplatte 17 und sitzseitig eine Sitztrageplatte 18 auf. Die Sitztrageplatte 18 ist mit einem kastenförmigen Aufsatz 19 fest verbunden. Der Aufsatz 19 wiederum ist mit der Unterseite 3 des Sitzes 2 derart verbunden, daß er von einem Besucher praktisch nicht abmontiert werden kann. Die Sitztrageplatte 18 und die Halteplatte 17 müssen nicht, wie dargestellt, im wesentlichen durchgängig sein, sondern können auch Unterbrechungen aufweisen.A first embodiment of a seat bracket 15 and their pivot bearing 16 are in Figures 3 and 4 in detail to recognize. The seat bracket 15 has on the grandstand side one on the horizontal step surface 11a of the grandstand fixed, stationary holding plate 17 and seat side a seat support plate 18. The seat support plate 18 is firmly connected with a box-shaped attachment 19. The Attachment 19 is in turn with the underside 3 of the seat 2 so connected that it is practical by a visitor cannot be removed. The seat support plate 18 and the holding plate 17 need not, as shown, essentially be consistent, but can also have interruptions exhibit.

Zur Radiallagerung des Schwenklagers 16 weist die Sitztrageplatte 18 eine zentrale Bohrung auf, in die eine Schraube 20 eingreift. Die Schraube 20 ist in ein tribünenseitig vorgesehenes Sicherungselement 21, hier einen in die Betonstufe eingelassenen Dübel 22, eingeschraubt. Bei einer Tribünenkonstruktion aus Stahl kann die Schraube 20 mit einem entsprechenden Innengewinde der Stahlkonstruktion zusammenwirken.For the radial mounting of the pivot bearing 16, the seat support plate 18 a central hole in the one Screw 20 engages. The screw 20 is in a tribune side provided securing element 21, here one dowel 22 embedded in the concrete step, screwed in. With a steel grandstand construction, the screw can 20 with a corresponding internal thread of the steel structure interact.

In der dargestellten Ausführungsform hat auch die Halteplatte 17 eine zentrale Bohrung, in die die Schraube 20 eingreift. Somit dient die Schraube 20 zugleich zur Befestigung der Halteplatte 17 an der horizontalen Stufenfläche 11a der Tribünenstufe 10. Die Halteplatte 17 könnte auch über gesonderte Befestigungsmittel an der Tribünenstufe 10 befestigt sein.In the illustrated embodiment, the holding plate also has 17 a central bore into which the screw 20 intervenes. Thus, the screw 20 also serves for attachment the holding plate 17 on the horizontal step surface 11a of the grandstand level 10. The holding plate 17 could also via separate fasteners on the grandstand step 10 be attached.

Die Unterseite des Schraubenkopfes 24 bzw. eines den Schraubenkopf 24 umgebenden Fixierungselements 25 wirkt mit einem die Bohrung einfassenden Rand 26 der Sitztragplatte 18 derart formschlüssig zusammen, daß diese gegen Abheben in axialer Richtung nach oben befestigt ist, wenn die Schraube 20 in den Dübel 22 eingeschraubt ist.The underside of the screw head 24 or one of the Screw head 24 surrounding fixing element 25 acts with an edge 26 of the seat support plate enclosing the bore 18 so positively together that these against Lifting is fastened upwards in the axial direction, if the screw 20 is screwed into the dowel 22.

Zwischen der Unterseite des Schraubenkopfes 24 und der horizontalen Stufenfläche 11a ist ein Abstandshalterstück 23 angeordnet, das hier als eine den Schaft 28 der Schraube 20 umgebende Distanzbuchse 27 ausgebildet ist. Die axiale Höhe der Distanzbuchse 27 ist derart bemessen, daß die Schraube 20 fest in den Dübel 22 eingeschraubt werden und sich die Sitztrageplatte 18 trotzdem gegenüber der Halteplatte 17 drehen kann.Between the bottom of the screw head 24 and the horizontal step surface 11a is a spacer piece 23 arranged here as a shaft 28 of the Screw 20 surrounding spacer 27 is formed. The axial height of the spacer bushing 27 is dimensioned such that that the screw 20 is screwed firmly into the dowel 22 be and the seat support plate 18 still opposite the holding plate 17 can rotate.

In der beschriebenen Ausführung läßt sich somit die Sitzhalterung mit einem einzigen zentralen Befestigungselement einfach und rationell befestigen. In the described embodiment, the seat holder can thus with a single central fastener fasten easily and efficiently.

Zur Axiallagerung des Schwenklagers 16 ist an der Halteplatte 17 (oder einer anderen tribünenseitigen, ortsfesten Baueinheit der Sitzhalterung 15) ein die Schwenkachse A in radialem Abstand umgebendes tribünenseitiges erstes Lagerteil 29 vorgesehen. An der Sitztrageplatte 18 (oder einer anderen sitzseitigen, schwenkbaren Baueinheit der Sitzhalterung 15), ist in entsprechendem radialen Abstand ein sitzseitiges zweites Lagerteil 30 ausgebildet, das sich gegen eine obere Stützfläche des tribünenseitigen Lagerteils abstützt.For the axial mounting of the pivot bearing 16 is on the holding plate 17 (or another stand-side, stationary Assembly of the seat bracket 15) the pivot axis A surrounding the stands at a radial distance first bearing part 29 provided. On the seat support plate 18 (or another seat-side, swiveling assembly the seat bracket 15) is at a corresponding radial distance a second bearing part 30 on the seat side is formed, that is against an upper support surface of the tribune-side Bearing part supports.

Mindestens eines der Lagerteile 29, 30 umgibt die Schwenkachse A wenigstens abschnittsweise ringförmig. Wie in Fig. 4 zu erkennen ist, wird bei der dargestellten Ausführungsform das tribünenseitige Lagerteil 29 durch Segmente eines die Schwenkachse A umgebenden Rings gebildet, während das sitzseitige Lagerteil 30 als unsegmentierter Ring mit einem äußeren Durchmesser b ausgebildet ist.At least one of the bearing parts 29, 30 surrounds the Swivel axis A at least in sections ring-shaped. How 4 can be seen in the illustrated Embodiment, the bearing part 29 on the grandstand side Segments of a ring surrounding the pivot axis A are formed, while the seat-side bearing part 30 as unsegmented Ring formed with an outer diameter b is.

Die Axiallagerung des Schwenklagers 16 erfolgt achsfern, d.h. radial beabstandet von der Schwenkachse A, und dient u.a. dazu, durch die Sitzlast verursachte Kippmomente aufzunehmen. Sie bildet somit ein achsfernes Drucklastlager 31 und ermöglicht ein insgesamt stabiles Schwenklager mit geringem Materialaufwand.The axial bearing of the pivot bearing 16 is remote from the axis, i.e. radially spaced from the pivot axis A, and serves et al in addition, tilting moments caused by the seat load take. It thus forms a pressure load bearing remote from the axis 31 and enables an overall stable pivot bearing with little material.

Beim Schwenken des Sitzes 2 gleitet das sitzseitige Lagerteil 30 auf dem tribünenseitigen Lagerteil 29 und stützt sich an ihm ab. Soweit ein leichtes Gleiten dieses Gleitlagers gewünscht ist, kann das Lagerteil 30 eine glatte untere Ringlagerfläche und das Lagerteil 29 eine reibungsarme Oberfläche 32 aufweisen. Die reibungsarme Oberfläche 32 wird vorzugsweise dadurch geschaffen, daß das Lagerteil 29 an seiner Oberfläche 32 mindestens abschnittsweise ein das Gleiten förderndes Kunststoffmaterial, insbesondere Polyamid, enthält. Beispielsweise kann das Lagerteil 29 mit dem Kunststoffmaterial beschichtet sein.When pivoting the seat 2, the seat-side bearing part slides 30 on the tribune-side bearing part 29 and is supported on him. So much for an easy glide this Plain bearing is desired, the bearing part 30 can smooth lower ring bearing surface and the bearing part 29 a have low-friction surface 32. The low friction Surface 32 is preferably created in that the bearing part 29 on its surface 32 at least in sections a plastic material that promotes sliding, especially polyamide. For example can the bearing part 29 coated with the plastic material his.

Die mit dem Sitz in Wirkverbindung stehende Sitztrageplatte 18 dreht sich um die ortsfeste Schraube 20, die Distanzbuchse 27 und das Fixierungselement 25, während die glatte Ringlagerfläche auf der Oberfläche 32 des Lagerteils 29 gleitet. Von der Halteplatte 17 steht ein Zapfen 33 ab, der in eine in der Sitztrageplatte 18 ausgebildete korrespondierende Ausnehmung 34 bewegbar eingreift. Durch das Anschlagen des Zapfens 33 an eine linke bzw. rechte Anschlagswand 35a,35b der Ausnehmung 34 werden Begrenzugungsanschläge gebildet, die die Schwenkbewegung des Sitzes 2 begrenzen. In Figur 4 ist die Lage der Ausnehmung 34 für unterschiedliche Positionen des Sitzes 2 angedeutet. Dabei ist die Lage der Ausnehmung 34 in einer nicht ausgelenkten Grundposition des Sitzes 2 mit einer durchgängigen Linie dargestellt, während die strich-punktierten Linien die Lage der Ausnehmung 34 markieren, wenn er sich in einer Schwenkposition befindet, d.h. aus seiner Grundposition ausgelenkt ist. Der Zapfen kann sich natürlich auch an der Sitztrageplatte und die Ausnehmung an der Halteplatte befinden. Die Begrenzungsanschläge an der Sitzhalterung 15 ermöglichen eine schnelle Ausrichtung einer großen Zahl von Sitzen 2. Vorzugsweise sind sie so angeordnet, daß der Sitz 2 beim Anschlagen eines Begrenzungsanschlages auf jeweils einen der wichtigsten Aktionsorte ausgerichtet ist.The seat support plate that is operatively connected to the seat 18 rotates around the fixed screw 20, the Spacer 27 and the fixing element 25 while the smooth ring bearing surface on the surface 32 of the bearing part 29 slides. From the holding plate 17 is a Pin 33 from the one formed in the seat support plate 18 corresponding recess 34 engages movably. By striking the pin 33 on a left or right stop wall 35a, 35b of the recess 34 Limitation stops formed that the swivel movement limit the seat 2. In Figure 4 is the location the recess 34 for different positions of the Seat 2 indicated. The position of the recess 34 is in an undeflected basic position of the seat 2 shown with a solid line, while the Dash-dotted lines mark the position of the recess 34, when he is in a swivel position, i.e. is deflected from its basic position. The cone can of course also on the seat support plate and the Recess on the holding plate. The limit stops on the seat bracket 15 allow a quick alignment of a large number of seats 2. Preferably they are arranged so that the seat 2 when striking a limit stop to one of the most important places of action.

Durch die Abmessung der Ausnehmung 34 läßt sich der durch einen Pfeil symbolisierte maximale Einstellbereich 36 des Sitzes 2 einstellen. Dieser beträgt vorzugsweise höchstens 60°, besonders bevorzugt höchstens 30°. The dimension of the recess 34 allows the through an arrow symbolized the maximum setting range 36 of the Adjust seat 2. This is preferably at most 60 °, particularly preferably at most 30 °.

In der durch das Drucklastlager 31 definierten Drehebene ist eine Blattfeder 37 angeordnet, deren eines Ende an dem zwischen der Unterseite des Schraubenkopfes 24 und der Distanzbuchse 27 festgeklemmten Fixierungselement 25 befestigt ist (drehfestes Ende 38) und deren anderes Ende über einen Halter 39 mit der Sitztrageplatte 18 verbunden und damit beweglich ist (drehfestes Ende 40). Wie in Figur 4 zu erkennen, wird das drehbewegliche Ende 40 der Blattfeder 37 beim Schwenken des Sitzes 2 aus seiner Ruheposition (durchgezogene Linie) ausgelenkt (strich-punktiert dargestellt). Durch die Auslenkung der Blattfeder 37 wird der Sitz 2 in die Grundposition zurückgedrängt. Die Fixierung des drehfesten Endes 38 erfolgt bevorzugt möglichst achsnah, um eine Streckung der Blattfeder 37 zu verhindern. Anderenfalls kann der Halter 39 auch derart gestaltet sein, daß er eine Längsbewegung der Blattfeder 37 zuläßt. Die Federrückstellung 41 kann auch anders ausgebildet sein. Beispielsweise kann sie eine Schraubenfeder umfassen, die an der Sitzhalterung derart angeordnet ist, daß sie zusammengedrückt wird, wenn der Sitz sich aus der Grundposition in seine Schwenkposition bewegt.In the rotary plane defined by the pressure load bearing 31 a leaf spring 37 is arranged, one end of which between the bottom of the screw head 24 and the spacer 27 clamped fixation element 25th is fixed (non-rotatable end 38) and the other end connected to the seat support plate 18 via a holder 39 and is therefore movable (non-rotatable end 40). As in figure 4, the rotatable end 40 of the Leaf spring 37 when pivoting the seat 2 from its rest position (solid line) deflected (dash-dotted ) Shown. By deflecting the leaf spring 37 the seat 2 is pushed back into the basic position. The rotationally fixed end 38 is preferably fixed as close to the axis as possible to extend the leaf spring 37 prevent. Otherwise, the holder 39 can also be used in this way be designed so that it has a longitudinal movement of the leaf spring 37 permits. The spring return 41 can also be designed differently his. For example, it can be a coil spring comprise, which are arranged on the seat holder in this way is that it compresses when the seat is down moved from the basic position to its swivel position.

Bei der beschriebenen Sitzhalterung 15 bildet die Sitztrageplatte 18 mit dem kastenförmigen Aufsatz 19 einen im wesentlichen umschlossenen Raum 42, in dem die Befestigungs- und Lagerelemente der Sitzhalterung 15, die Begrenzungsanschläge und die Blattfeder 37 angeordnet sind. Im Benutzungszustand des Sitzes 2 sind diese somit für einen Besucher der Veranstaltung nicht zugänglich. Durch die kompakte Bauweise und die verwendeten Materialien ist die Sitzhalterung 15 sehr robust. Die Sitze 2 können vorteilhaft einstückige Kunststoffformteile sein, die aus einem schlagfesten, bruchsicheren Kunststoff bestehen. Ist ein höherer Nutzungskomfort, beispielsweise bei Bestuhlungssystemen von Mehrzweckhallen, erwünscht, können die Sitze 2 auch jeweils eine um eine horizontale Drehachse schwenkbare, verstellbare Rückenlehne 5 haben.In the described seat bracket 15 forms the seat support plate 18 with the box-shaped attachment 19 in essentially enclosed space 42 in which the fastening and bearing elements of the seat bracket 15, the limit stops and the leaf spring 37 are arranged. When the seat 2 is in use, they are therefore for not accessible to a visitor to the event. By is the compact design and the materials used the seat bracket 15 very robust. The seats 2 can be advantageous be one-piece molded plastic parts made of made of an impact-resistant, unbreakable plastic. Is a higher convenience, for example at Seating systems of multi-purpose halls, desired, can the seats 2 also one by one horizontal Have pivotable, adjustable backrest 5.

In Figur 5 sind drei auf einer horizontalen Stufenfläche 11a angebrachte Sitzeinheiten 1a,1b,1c des erfindungsgemäßen Bestuhlungssystems dargestellt. Gestrichelt angedeutet sind die Drucklastlager 31a,31b,31c der Schwenklager 16. Zu erkennen ist, daß der äußere Durchmesser d des Drucklastlagers 31 und damit des Lagerteils 30 relativ groß ist. Vorzugsweise entspricht er mindestens einem Drittel, bevorzugt mindestens der Hälfte der Breite b des Sitzes 2. Je größer der Durchmesser d ist, um so besser werden die Kippmomente zwischen Sitz 2 und Sitzhalterung 15 aufgenommen. Die beiden äußeren Sitze 2a,2c befinden sich jeweils in ihrer Grundposition, die hier so ausgerichtet ist, daß die Sitzvorderseite 4 im wesentlichen parallel zu einer vertikalen Stufenfläche 12 der Tribünenstufe 10 orientiert ist. Dies entspricht beispielsweise bei Stadien der Position, in der die Sitze 2 auf das Spielfeld ausgerichtet sind.In Figure 5 there are three on a horizontal step surface 11a attached seat units 1a, 1b, 1c of the invention Seating system shown. Dashed lines the pressure load bearings 31a, 31b, 31c are the pivot bearings 16. It can be seen that the outer diameter d of the Pressure load bearing 31 and thus the bearing part 30 relative is great. It preferably corresponds to at least one Third, preferably at least half of the width b of the Seat 2. The larger the diameter d, the better the tilting moments between seat 2 and seat bracket 15 added. The two outer seats 2a, 2c are located each in its basic position, which is aligned here is that the front seat 4 essentially parallel to a vertical step surface 12 of the grandstand step 10 is oriented. This corresponds, for example at stages of the position in which the seats 2 are on the playing field are aligned.

Für den Sitz 2b der mittleren Sitzeinheit 1b sind zwei Schwenkpositionen gestrichelt dargestellt, die symmetrisch um die Grundposition angeordnet sind. Es sind jedoch Ausführungen möglich, in denen die Schwenkpositionen nicht symmetrisch zu der Grundposition liegen oder der Sitz 2 nur in eine Richtung einstellbar ist. Der Pfeil markiert den durch Begrenzungsanschläge begrenzten Einstellbereich 36 des Sitzes 2.There are two for the seat 2b of the middle seat unit 1b Swivel positions shown in dashed lines that are symmetrical are arranged around the basic position. However, there are Versions possible in which the swivel positions not symmetrical to the basic position or the Seat 2 is adjustable in one direction only. The arrow marks the setting range limited by limit stops 36 of seat 2.

Die in den Figuren 6 bis 8 dargestellte Ausführungsform einer Sitzeinheit weist eine Arretierungseinrichtung 45 auf, mittels der der Sitz 2 in mehreren unterschiedlichen Schwenkpositionen arretierbar ist. Bei der dargestellten Ausführungsform einer solchen Arretierungseinrichtung sind zwei Teile der Sitzhalterung, nämlich die an der Tribünenstufe 10 befestigte Halteplatte 17 und die mit dem Sitz 2 verbundene Sitztrageplatte 18, gegen die Kraft einer Feder 46 axial auseinanderziehbar. Dies wird bei der dargestellten Konstruktion auf einfache und robuste Weise dadurch erreicht, daß die Feder 46 als eine einen zentralen Achsbolzen 47 umgebende auf Druck belastete Spiralfeder ausgebildet ist, die sich einerseits gegen die Unterseite der Halteplatte 17 und andererseits gegen einen am unteren Ende des Bolzens 47 radial vorstehenden Kragen 48 abstützt. Dadurch, daß sich der ebenfalls radial vorstehende Kopf 49 des Bolzens 47 mit seiner Unterseite gegen die Oberseite der Sitztrageplatte 18 abstützt, wird die gewünschte axiale Federspannung zwischen den Teilen 17 und 18 erreicht.The embodiment shown in Figures 6 to 8 a seat unit has a locking device 45 on, by means of which the seat 2 in several different Swivel positions can be locked. In the illustrated Embodiment of such a locking device are two parts of the seat bracket, namely the one on the Grandstand stage 10 attached holding plate 17 and with the seat support plate 18 connected to the seat 2, against the force a spring 46 axially separable. This will be at the construction shown on simple and robust Achieved in that the spring 46 as one central axle bolt 47 surrounding pressure-loaded Spiral spring is formed, the one against the underside of the holding plate 17 and on the other hand against one radially protruding at the lower end of the bolt 47 Collar 48 supports. Because that is also radial protruding head 49 of the bolt 47 with its underside supports against the top of the seat support plate 18, the desired axial spring tension between parts 17 and 18 reached.

Bei dieser Ausführungsform ist die Halteplatte 17 nicht, wie bei den Figuren 2 bis 4, zentral befestigt, sondern durch Schrauben 50. Dabei ist die in den Figuren dargestellte Querschnittsform der Halteplatte 17 mit einem auf der Tribünenstufe 10 aufliegenden äußeren Bereich 51 und einem nach oben hochgewölbten inneren Bereich 52 vorteilhaft.In this embodiment, the holding plate 17 is not as in Figures 2 to 4, centrally attached, but by screws 50. The one shown in the figures Cross-sectional shape of the holding plate 17 with one the outer area 51 and the stage level 10 an upwardly curved inner region 52 is advantageous.

Die Arretierungseinrichtung 45 umfaßt weiterhin (mindestens) einen an einem der beiden Teile 17 bzw. 18 axial vorstehenden Vorsprung 53 und mehrere an dem anderen Teil 18 bzw. 17 vorgesehene, in verschiedenen Umfangspositionen angeordnete, zu dem Vorsprung 53 passende und mit diesem formschlüssig zusammenwirkende Ausnehmungen 54. Bei der dargestellten Ausführungsform sind der Vorsprung 53 und die Ausnehmungen 54 an den beiden Lagerteilen des achsfernen Drucklastlagers 31, nämlich dem sitzseitigen Lagerteil 30 bzw. dem tribünenseitigen Lagerteil 29, vorgesehen. Die beiden Lagerteile 29, 30 werden bei der dargestellten Konstruktion durch je einen Flachstahlring 55 bzw. 56 gebildet, der mit der Halteplatte 17 bzw. der Sitztrageplatte 18 verschweißt ist. Der Vorsprung 53 und die Ausnehmungen 54 sind an diesen Flachstahlringen ausgebildet.The locking device 45 further comprises (at least) one on one of the two parts 17 and 18 axially protruding projection 53 and several on the other part 18 or 17 provided, in different circumferential positions arranged, matching the projection 53 and with this form-fittingly interacting recesses 54. In the illustrated embodiment, the protrusion 53 and the recesses 54 on the two bearing parts of the Thrust load bearing 31 remote from the axis, namely the seat-side Bearing part 30 or the bearing part 29 on the grandstand side, intended. The two bearing parts 29, 30 are in the shown construction by a flat steel ring 55 and 56 formed, with the holding plate 17 and the Seat support plate 18 is welded. The projection 53 and the recesses 54 are formed on these flat steel rings.

Bei der in den Figuren 6 bis 8 dargestellten Konstruktion kann der Sitz 2 zusammen mit der Rückenlehne 5 leicht in unterschiedliche Beobachtungsrichtungen geschwenkt werden. Zu diesem Zweck wird der Sitz zusammen mit dem daran befestigten Teil 18, 56 der Sitzhalterung gegen die Kraft der Feder 46 angehoben, so daß der Vorsprung 53 nicht mehr in die Ausnehmung 54 eingreift. Anschließend wird der Sitz in eine Rotationsposition geschwenkt, in der der Vorsprung 53 mit einer der anderen Ausnehmungen 54 fluchtet, dort wieder abgesenkt und dadurch arretiert. Um dies zu erleichtern, ist die in Fig. 8 dargestellte Formgebung des Vorsprungs 53 mit konischen Seitenflächen 53a vorteilhaft. Besonders bevorzugt weist auch die Ausnehmung 54 - ebenfalls wie dargestellt - eine entsprechend konische Seitenfläche 54a auf. Selbstverständlich kann eine größere Anzahl von Ausnehmungen 54 vorgesehen sein, um die Arretierung des Sitzes in weiteren Beobachtungspositionen zu ermöglichen.In the construction shown in Figures 6 to 8 can the seat 2 together with the backrest 5 easily in different observation directions can be swiveled. For this purpose, the seat is attached to it attached part 18, 56 of the seat bracket against the force the spring 46 raised so that the projection 53 does not engages more in the recess 54. Then will the seat is pivoted into a rotational position in which the Projection 53 is aligned with one of the other recesses 54, lowered there again and thereby locked. To do this to facilitate, is the shape shown in Fig. 8 of the projection 53 with conical side surfaces 53a advantageous. The recess also particularly preferably has 54 - also as shown - a correspondingly conical Side surface 54a. Of course, one larger number of recesses 54 may be provided in order locking the seat in further observation positions to enable.
