Abstract

The chair has a seat with a seat surface, and a closing bar pivotally mounted between a closed position and an open position, where the closing bar has a crossbar to be disposed across thighs of a passenger on the seat in the closed state. A locking mechanism has a contact surface that extends substantially parallel to the crossbar, and the contact surface faces towards the seat surface, where a distance between the contact surface and the seat surface is variable.

Description

Die Erfindung betrifft einen Sessel eines Sesselliftes mit wenigstens einem Sitz mit einer Sitzfläche und mit einem verschwenkbaren Schließbügel, dessen Querbügel im geschlossenen Zustand quer über den Oberschenkeln eines Fahrgastes angeordnet ist, wobei am Querbügel eine den Abstand zwischen diesem und der Sitzfläche verringernde Sicherungseinrichtung angeordnet ist.The invention relates to a chair of a chairlift with at least one seat with a seat and a pivoting striker, the crossbar is arranged in the closed state across the thighs of a passenger, wherein the transverse bar a the distance between this and the seat reducing securing device is arranged.

Sessel für Sessellifte wiesen in früheren Zeiten ein bis zwei Sitze, neuerdings aber meist vier bis acht nebeneinander liegende Sitze auf. Um ein Herausfallen oder Abrutschen der Fahrgäste vom Sessel zu verhindern weisen diese Sessel Schließbügel auf, die über die gesamte Breite des Sessels gehen. Diese Schließbügel können über im Bereich der Rückenlehne liegende Schwenkachsen von einer Position, in der sie über den Fahrgästen liegen, in eine Position, verschwenkt werden, in der sich ein Querbügel vor den Fahrgästen über deren Oberschenkel erstreckt. Des Weiteren ist an den Schließbügeln noch eine der Anzahl der Sitze entsprechende Anzahl von Fußrasten vorgesehen.Armchairs for chairlifts used to have one to two seats in earlier times, but most recently four to eight seats side by side. In order to prevent the passengers from falling out or slipping off the chair, these armchairs have closing bars that run the entire width of the chair. These strikers can be pivoted about lying in the region of the backrest pivot axes from a position in which they lie above the passengers, in a position in which extends a cross bar in front of the passengers on their thighs. Furthermore, a number of seats corresponding number of footrests is still provided on the strikers.

In der Schließstellung verhindert der Schließbügel, insbesondere der Querbügel, in der Regel zuverlässig ein Abrutschen oder Herausfallen von Erwachsenen. Da der Abstand zwischen Querbügel und Sitzfläche jedoch so dimensioniert ist, dass auch große Fahrgäste mit längeren Beinen unter dem Querbügel bequem Platz finden, ist dieser Abstand in der Regel für kleinere Personen zu groß, sodass ein Durchrutschen dieser kleineren Personen unter dem Querbügel möglich ist, insbesondere wenn diese auf Grund ihrer kürzeren Beine nicht in der Lage sind diese auf den Fußrasten abzustützen.In the closed position prevents the striker, in particular the crossbar, usually reliably slipping or falling out of adults. However, since the distance between the cross bar and seat is dimensioned so that even large passengers with longer legs under the crossbar find comfortable place, this distance is usually too small for smaller people, so slipping these smaller people under the crossbar is possible especially if they are not able to support them on the footrests due to their shorter legs.

Um diese Gefahr zu vermindern wurden bereits Vorschläge gemacht wie sie beispielsweise aus der AT 411 523 B und der AT 411 046 B bekannt sind. Die aus diesen Vorveröffentlichungen bekannten Maßnahmen können im Wesentlichen dahingehend zusammengefasst werden, dass Schutzbügel oder Nocken von oben oder von unten zwischen den Oberschenkeln des jeweiligen Benutzers angeordnet werden. Dies wird von den Fahrgästen bzw. Benutzern aber in manchen Fällen als unangenehm empfunden bzw. bietet keinen Schutz, wenn ein kleiner Fahrgast so sitzt, dass dieser Schutzbügel bzw. die Nocke nicht zwischen den Beinen sondern neben dem Fahrgast liegt.In order to reduce this risk, proposals have already been made, such as those from the AT 411 523 B and the AT 411 046 B are known. The measures known from these prior publications can essentially be summarized in that protective straps or cams are arranged from above or from below between the thighs of the respective user. This is perceived by the passengers or users in some cases as unpleasant or offers no protection when a small passenger sits so that this guard or the cam is not between the legs but next to the passenger.

Der Erfindung liegt daher die Aufgabe zu Grunde eine Vorrichtung der eingangs genannten Gattung zur Verfügung zu stellen, die unabhängig von der Größe der Person und deren Sitzposition auf dem Sessel ein Durchrutschen zwischen Sitzfläche und Querbügel zuverlässig verhindert.The invention is therefore based on the object to provide a device of the type mentioned available, regardless of the size of the person and their sitting position on the chair slippage between the seat and crossbar reliably prevented.

Gelöst wird diese Aufgabe bei einem gattungsgemäßen Sessel dadurch, dass die Sicherungseinrichtung eine sich im Wesentlichen parallel zum Querbügel erstreckende und der Sitzfläche zugewandte Auflagefläche aufweist, deren Abstand zur Sitzfläche veränderbar ist und dass die Sicherungseinrichtung am Oberschenkel eines Fahrgastes anliegend gegen eine elastische Kraft relativ zum Querbügel bewegbar ist.This object is achieved in a generic chair in that the securing device has a substantially parallel to the cross bar extending and the seat facing support surface whose distance from the seat is variable and that the safety device on the thigh of a passenger fitting against an elastic force relative to the crossbar is movable.

Die Auflagefläche am Querbügel ist bei der Erfindung im Wesentlichen parallel zum Querbügel angeordnet und liegt von oben auf den Oberschenkeln der Benutzer auf, wobei durch den Umstand, dass der Abstand der Auflagefläche von der Sitzfläche veränderbar ist, eine selbsttätige Anpassung an die Länge der Beine bzw. Stärke der Oberschenkel erfolgt. Dadurch wird verhindert, dass große Personen von der Sicherungseinrichtung eingeengt werden, wogegen bei kleinen Personen ein sicherer Halt gewährleistet ist. Durch den bei Bedarf einstellbaren leichten Druck der Sicherungseinrichtung auf die Oberschenkel der Fahrgäste wird außerdem das subjektive Sicherheitsgefühl, insbesondere von etwas unsicheren Personen erhöht, da diese einen verbesserten Halt durch den Kontakt mit dem Sicherheitsbügel spüren. Schließlich ist gewährleistet, dass jede Person, egal ob sie auf einem Sitz korrekt in der Mitte sitzt, oder, was bei Sesselliften mit drei oder mehr Sitzplätzen gelegentlich vorkommt, in der Mitte zwischen zwei Sitzen sitzt, zuverlässig gegen Abrutschen gesichert ist.In the case of the invention, the bearing surface on the transverse bow is arranged essentially parallel to the transverse bow and rests on the thighs of the user from above, wherein the fact that the distance between the bearing surface and the seat surface makes it possible to adapt automatically to the length of the legs or legs Thigh strength. This prevents large persons from being restricted by the securing device, whereas a secure hold is ensured in the case of small persons. Due to the adjustable if necessary, light pressure of the safety device on the thighs of the passengers also the subjective sense of security, especially of somewhat insecure people is increased because they feel an improved grip through the contact with the safety bar. Finally, it is ensured that each person, whether seated correctly in the middle of a seat or, in the case of chair lifts with three or more seats, occasionally sitting in the middle between two seats, is reliably secured against slipping.

In einer bevorzugten Ausführungsform der Erfindung erstreckt sich die Sicherungseinrichtung im Wesentlichen über die gesamte Breite der Sitzfläche, da in diesem Fall wie bereits erwähnt jede Person in jeder Sitzposition gesichert wird.In a preferred embodiment of the invention, the securing device extends substantially over the entire width of the seat, as in this case, as already mentioned, each person is secured in any seating position.

In einer weiteren Ausführungsform, bei der der Sessel zwei oder mehr Sitzflächen aufweist, kann erfindungsgemäß vorgesehen sein, dass sich die Sicherungseinrichtung über wenigstens zwei nebeneinander liegende Sitzflächen erstreckt. Dies stellt nicht nur eine einfache Konstruktion dar, da nicht für jeden Sitz eine eigene Sicherungseinrichtung gebaut und angebracht werden muss, sondern gewährleistet wie bereits weiter oben angeführt auch, dass auch Personen gesichert werden, die zwischen zwei Sitzplätzen sitzen.In a further embodiment, in which the armchair has two or more seating surfaces, it can be provided according to the invention that the securing device extends over at least two adjacent seating surfaces. This not only represents a simple construction, since not for each seat own safety device must be built and installed, but guaranteed As already mentioned above, it is also possible to secure persons sitting between two seats.

Eine besonders einfache und zuverlässige Ausführungsform der Erfindung ist dadurch gekennzeichnet, dass sich die Sicherungseinrichtung über die gesamte Sesselbreite erstreckt, wodurch sich die vorstehend angegebenen Vorteile besonders gut ausnützen lassen.A particularly simple and reliable embodiment of the invention is characterized in that the securing device extends over the entire armchair width, whereby the advantages given above can be exploited particularly well.

Grundsätzlich sind bei der Erfindung Ausführungsformen denkbar, die dadurch gekennzeichnet sind, dass der Abstand zwischen Auflagefläche und Querbügel veränderbar ist. Das heißt, dass die Auflagefläche je nach Beinlänge bzw. Oberschenkelstärke zum Querbügel hin drückbar oder verschiebbar ist.In principle, embodiments are conceivable in the invention, which are characterized in that the distance between the support surface and the transverse clamp is variable. This means that the bearing surface can be pushed or moved towards the crossbar depending on the leg length or thigh thickness.

Eine in diesem Zusammenhang bevorzugte Ausführungsform ist dadurch gekennzeichnet, dass die Auflagefläche an einem elastisch deformierbaren Element der Sicherungseinrichtung angeordnet ist. In einer praktischen Ausführungsform wäre die Sicherungseinrichtung z.B. ein aus deformierbarem Kunststoff, z.B. Schaumgummi, hergestellter länglicher Teil, der einerseits am Querbügel befestigt ist, und dessen Auflagefläche anderseits den Oberschenkeln der Fahrgäste zugewandt ist.A preferred embodiment in this context is characterized in that the bearing surface is arranged on an elastically deformable element of the securing device. In a practical embodiment, the securing means would be e.g. a deformable plastic, e.g. Foam rubber, manufactured elongated part, which is on the one hand attached to the crossbar, and the bearing surface on the other hand, the thighs of the passengers faces.

In einer anderen Ausführungsform würde die Sicherungseinrichtung nicht zur Gänze aus den elastisch deformierbaren Element bestehen, sondern das elastisch deformierbare Element wäre nur über einen Träger od. dgl. mit dem Querbügel verbunden.In another embodiment, the securing device would not consist entirely of the elastically deformable element, but the elastically deformable element would od only via a carrier. Like. Connected to the crossbar.

Eine weitere bevorzugte Ausführungsform der Erfindung ist dadurch gekennzeichnet, dass die Auflagefläche an einem Sicherungsbügel der Sicherungseinrichtung angeordnet ist, der im Wesentlichen parallel zum Querbügel angeordnet ist.A further preferred embodiment of the invention is characterized in that the support surface is arranged on a securing bracket of the securing device, which is arranged substantially parallel to the crossbar.

Dieser Sicherungsbügel könnte z. B. ein Stahl- oder Kunststoffrohr sein, das am Querbügel befestigt ist. An diesem Sicherungsbügel könnte sich direkt die Auflagefläche befinden. Es wäre allerdings auch möglich, dass am Sicherungsbügel das elastisch deformierbare Element angeordnet ist, das die Auflagefläche trägt, der Sicherungsbügel somit den Träger für das Element bildet.This circlip could z. B. be a steel or plastic tube, which is attached to the crossbar. At this circlip could be directly the bearing surface. However, it would also be possible that the elastically deformable element is arranged on the securing bracket, which carries the support surface, the securing bracket thus forms the support for the element.

Der Sicherungsbügel kann bei der Erfindung gegen eine elastische Kraft relativ zum Querbügel bewegbar sein, wobei die elastische Kraft beispielsweise von einer oder mehreren Stahlfedern aufgebracht werden kann. Diese Feder drückt den Sicherungsbügel mit leichter Kraft gegen die Oberschenkel der Fahrgäste sobald der Schließbügel in seine Schließstellung verschwenkt wird.The securing bracket can be movable in the invention against an elastic force relative to the crossbar, wherein the elastic force can be applied for example by one or more steel springs. This spring pushes the safety bar with light force against the thighs of the passengers as soon as the striker is pivoted to its closed position.

Im Rahmen der Erfindung sind drei Ausführungsformen bevorzugt, wie der Sicherungsbügel relativ zum Querbügel bewegbar ist.In the context of the invention, three embodiments are preferred, as the securing bracket is movable relative to the crossbar.

Eine Ausführungsform ist dadurch gekennzeichnet, dass der Sicherungsbügel verschwenkbar gelagert ist.An embodiment is characterized in that the securing bow is pivotably mounted.

Eine zweite Ausführungsform ist dadurch gekennzeichnet, dass der Sicherungsbügel über längenveränderbare Stangen, z.B. Teleskopstangen, mit dem Querbügel verbunden ist.A second embodiment is characterized in that the securing clip is provided by means of length-adjustable rods, e.g. Telescopic rods, with the crossbar is connected.

Eine dritte Ausführungsform ist dadurch gekennzeichnet, dass der Sicherungsbügel über Kniegelenkhebel mit dem Querbügel verbunden ist.A third embodiment is characterized in that the securing bracket is connected via knee lever to the crossbar.

Um die Sicherheit gegen Durchrutschen weiter zu erhöhen kann schließlich auch vorgesehen sein, dass die Auflagefläche im Mittelbereich der Sitzfläche einen zur Sitzfläche hin weisenden, nasenartigen Vorsprung aufweist.Finally, in order to increase the safety against slipping, it can also be provided that the bearing surface has a nose-like projection facing the seat surface in the middle region of the seat surface.

Dieser nasenartige Vorsprung, der allerdings relativ geringe Ausmaße aufweisen kann, würde, wie an sich aus der AT 411 046 B bekannt, zwischen die Beine eines Fahrgastes ragen, wenn dieser korrekt auf dem Sitzplatz sitzt.This nose-like projection, which may, however, have relatively small dimensions, would, as in itself from the AT 411 046 B known to protrude between the legs of a passenger, if this sits correctly on the seat.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsformen der Erfindung.Further features and advantages of the invention will become apparent from the following description of preferred embodiments of the invention.

Die in den Fig. 1 bis 8 dargestellten Sessel eines Sesselliftes sind nur mit den für die Erfindung wesentlichen Teilen schematisch dargestellt, nämlich mit einer Sitzbank 1 und einem Schließbügel 2. Die übrigen Teile des Sessels können wie im Stand der Technik üblich ausgeführt sein. Es wird daher nur allgemein erwähnt, dass die Sitzbank 1 bzw. der Schließbügel 2 an einem Tragrahmen befestigt sind, der gegebenenfalls über ein Gelenk mit einer Tragstange verbunden ist, an deren oberen Ende eine Klemmeinrichtung zum Befestigen bzw. Ankuppeln des Sessels an ein Trag- und/oder Förderseil angebracht ist. Bei Bedarf kann auch ein Laufwerk am oberen Ende der Tragstange vorgesehen sein, welches nach dem Abkuppeln des Sessels vom Trag- und/oder Förderseil zum Verfahren des Sessels längs in den Stationen vorgesehener Schienen durch die Einstiegs- bzw. Ausstiegsbereiche dient.The in the Fig. 1 to 8 illustrated chair of a chairlift are shown schematically only with the essential parts of the invention, namely with a seat 1 and a striker 2. The other parts of the chair can be performed as usual in the art. It is therefore only mentioned in general terms that the seat 1 and the striker 2 are fastened to a support frame, which is optionally connected via a hinge to a support rod, at the upper end of a clamping device for attaching or coupling the armchair to a Trag- and / or hoisting rope is attached. If necessary, a drive can be provided at the upper end of the support rod, which serves after uncoupling of the chair from the support and / or hoisting rope for moving the armchair longitudinally provided in the stations rails through the entry and exit areas.

In den Fig. 1 und 2 ist eine erste Ausführungsform der Erfindung dargestellt, bei der wie erwähnt eine Sitzbank 1 mit vier Sitzflächen 3 und einer Rückenlehne 4 vorgesehen ist. Im Bereich der seitlichen, oberen Ecken der Rückenlehne 4 ist über nicht detailliert dargestellte Gelenke 5 ein Schließbügel 2 verschwenkbar gelagert, sodass der Schließbügel 2 von seiner in den Fig. 1 und 2 dargestellten Schließstellung um etwas mehr als 90° nach oben geschwenkt werden kann, sodass die Fahrgäste ungehindert ein- und aussteigen können.In the Fig. 1 and 2 a first embodiment of the invention is shown in which, as mentioned, a seat 1 with four seats 3 and a backrest 4 is provided. In the area of the lateral, upper corners of the backrest 4, a striker 2 is pivotally mounted about not shown in detail joints 5, so that the striker 2 of his in the Fig. 1 and 2 shown closed position can be pivoted by slightly more than 90 ° to the top, so that passengers can get in and out unhindered.

Der Schließbügel 2 besteht im Wesentlichen aus einem Querbügel 6, der sich über die gesamte Breite der Sitzbank 1 bzw. des Sessels erstreckt. Über Seitenstreben 7 ist der Querbügel 6 mit den Gelenken 5 verbunden. Von dem Querbügel 6 erstrecken sich zwischen jeweils zwei Sitzen zwei vertikale Stangen 8 nach unten, an denen jeweils zwei Fußrasten 9, eine für jeden Sitzplatz 3, befestigt sind.The striker 2 consists essentially of a cross bar 6, which extends over the entire width of the seat 1 and the chair. About side struts 7 of the cross bar 6 is connected to the joints 5. Of the cross bar 6 extend between each two seats two vertical bars 8 down to where two footrests 9, one for each seat 3, are attached.

Der Abstand zwischen der Querstrebe 6 und den Sitzflächen 3, insbesondere deren der Querstrebe 6 am nächsten liegende vordere Bereich, ist so bemessen, dass auch Personen mit längeren Beinen bzw. Unterschenkeln, aber auch korpulentere Personen bequem unter der Querstrebe 6 Platz finden, wenn sie ihre Füße auf die Fußrasten 9 aufsetzen. Auf der anderen Seite ist dieser Abstand für kleine Personen, insbesondere Kinder so groß bemessen, dass diese unter dem Querbügel 6 durchrutschen könnten. Diese Gefahr besteht insbesondere deswegen, weil bei kleineren Personen die Beine häufig zu kurz sind, um sie auf den Fußrasten 9 aufzusetzen.The distance between the transverse strut 6 and the seat surfaces 3, in particular whose transverse strut 6 closest to the front area is dimensioned so that even persons with longer legs or lower legs, but also corpulent people comfortably below the cross brace 6 find space when they put their feet on the footrests 9. On the other hand, this distance for small people, especially children sized so large that they could slip under the crossbar 6. This danger is particularly because in smaller persons, the legs are often too short to put them on the footrests 9.

Um diese Gefahr zu vermindern, sind bei der Erfindung Sicherungseinrichtungen 10 vorgesehen. Eine Sicherungseinrichtung 10 befindet sich jeweils im Bereich eines äußeren Sitzplatzes 3, wogegen sich eine mittlere Sicherungseinrichtung 10 über die beiden mittleren Sitzplätze 3 erstreckt. Die Sicherungseinrichtungen 10 weisen in diesem Ausführungsbeispiel jeweils einen Sicherungsbügel 11 auf, der über jeweils zwei Teleskopstangen 22 am Querbügel 6 befestigt ist. In den Teleskopstangen 22 sind Druckfedern 13 angeordnet, welche deren an den Sicherungsbügeln 11 angebrachte Abschnitte 14 vom Querbügel 6 weg, d.h. der in den Fig. 1 und 2 dargestellten Schließlage des Schließbügels 2 nach unten in Richtung zur Sitzfläche 3 hin drücken. An ihrer Unterseite weisen die Sicherungsbügel 1 Auflageflächen 12 auf, die sich auf Grund der Anordnung der Sicherungsbügel 11 im Wesentlichen parallel zum Querbügel 6 erstrecken. Mit den Auflageflächen 12 liegen die Sicherungsbügel 11 unter leichtem Druck der Federn 13 auf den Oberschenkeln der Fahrgäste auf, wobei sich der Abstand zwischen der Auflagefläche 12 und der Sitzfläche 3 durch die Teleskopstangen 22 entsprechend der Länge bzw. Stärke der Beine von alleine anpasst. Durch die federbelastete Ausführungsform der Sicherungseinrichtungen 10 mit den Teleskopstangen 22 ist ohne Zutun der Fahrgäste gewährleistet, dass die Sicherungsbügel 11 auf den Beinen der Fahrgäste aufliegen, wodurch hohe Sicherheit gegen Durchrutschen auch bei kleinen Personen gewährleistet ist.In order to reduce this risk, securing devices 10 are provided in the invention. A securing device 10 is located in each case in the region of an outer seat 3, whereas a central securing device 10 extends over the two middle seats 3. The securing devices 10 have in this embodiment in each case a securing bracket 11, which is fastened via two telescopic rods 22 on the crossbar 6. In the telescopic rods 22 compression springs 13 are arranged, which their attached to the circlips 11 sections 14 away from the cross bar 6, ie the in the Fig. 1 and 2 shown closing position of the striker 2 down in the direction of the seat surface 3 down. On their underside, the securing bow 1 bearing surfaces 12, which extend due to the arrangement of the securing bracket 11 is substantially parallel to the cross bar 6. With the support surfaces 12, the securing bracket 11 are under slight pressure of the springs 13 on the thighs of the passengers, with the distance between the support surface 12 and the seat 3 by the telescopic rods 22 according to the length or strength of the legs by itself adapts. By the spring-loaded embodiment of the safety devices 10 with the telescopic rods 22 is ensured without intervention of the passengers that the safety bar 11 rest on the legs of the passengers, which ensures high security against slipping even in small people.

Bei der in den Fig. 3 und 4 dargestellten Ausführungsform sind die Sitzbank 1 und der Schließbügel 2 mitsamt den Fußrasten 9 im Wesentlichen gleich wie in den Fig. 1 und 2 aufgebaut. Unterschiedlich ist allerdings die Art, wie die Sicherungsbügel 11 mit dem Querbügel 6 verbunden sind. Bei der in den Fig. 3 und 4 dargestellten Ausführungsform sind die Sicherungsbügel 11 über je zwei Kniegelenkhebel mit Hebelgliedern 15 und 16 mit dem Querbügel 6 verbunden. Der Druck auf die Sicherungsbügel 11 wird mit Druckfedern 17 ausgeübt, die zwischen den Sicherungsbügeln 11 und dem Querbügel 6 eingespannt sind. Alternativ wäre es z. B. auch möglich, im Bereich der Gelenke zwischen den Hebelgliedern 15 und dem Querbügel 6 und/oder bei an Gelenken zwischen den Hebelgliedern 15 und 16 und/oder an der gelenkigen Verbindung zwischen den Hebelgliedern 16 und den Sicherungsbügeln 11 Schenkelfedern anzubringen.In the in the 3 and 4 illustrated embodiment, the seat 1 and the striker 2 together with the footrests 9 are substantially the same as in the Fig. 1 and 2 built up. However, different is the way in which the securing bow 11 are connected to the cross bar 6. In the in the 3 and 4 illustrated embodiment, the securing bracket 11 via two knee lever with lever members 15 and 16 connected to the cross bar 6. The pressure on the securing bracket 11 is exerted by compression springs 17, which are clamped between the securing straps 11 and the cross bar 6. Alternatively, it would be z. B. also possible to install in the region of the joints between the lever members 15 and the cross bar 6 and / or at joints between the lever members 15 and 16 and / or on the articulated connection between the lever members 16 and the circlips 11 leg springs.

Eine weitere Ausführungsform der Erfindung ist in den Fig. 5 und 6 dargestellt, bei der die Sitzbank 1 und der Schließbügel 2 wieder wie in den vorhergehenden Ausführungsformen beschrieben aufgebaut sind. Der Sicherungsbügel 11 ist allerdings bei der Ausführungsform vom Fig. 5 und 6 über Schenkel 18 mit den Seitenstreben 7 des Querbügels 6 gelenkig verbunden. Im Bereich der beiden Gelenke 19 sind beispielsweise Schenkelfedern angebracht, welche den Sicherungsbügel 11 über die Schenkel 18 nach unten, d.h. vom Querbügel 6 weg in Richtung zur Sitzfläche 3 hin drücken.Another embodiment of the invention is in the FIGS. 5 and 6 represented, in which the seat 1 and the striker 2 are again constructed as described in the previous embodiments. However, the securing bracket 11 is in the embodiment of FIGS. 5 and 6 via legs 18 hingedly connected to the side struts 7 of the cross bar 6. In the region of the two joints 19, for example, torsion springs are attached, which press the securing clip 11 downwards over the legs 18, ie, away from the cross bar 6 in the direction of the seat surface 3.

Unterschiedlich zu den vorhergehenden Ausführungsformen ist auch noch, dass sich der Sicherungsbügel bei dieser Ausführungsform quer über die gesamte Breite des Sessels bzw. der Sitzbank 1 erstreckt.In contrast to the preceding embodiments, it is also the case that in this embodiment the securing bow extends across the entire width of the chair or the seat 1.

Bei der letzten in den Fig. 7 und 8 dargestellten Ausführungsform besteht die Sicherungseinrichtung 10 aus elastisch deformierbaren Elementen 20, wobei den beiden äußeren Sitzplätzen jeweils ein einzelnes Element 20 zugeordnet ist, wogegen sich das mittlere Element 20 über die gesamte Breite der beiden mittleren Sitzplätze erstreckt. Jedes Element 20 besteht beispielsweise aus kompressivem Kunststoff, z. B. Schaumstoff, der mit seiner vom Querbügel 6 abgewandten bzw. den symbolisch dargestellten Oberschenkeln 21 zugewandten Auflagefläche 12 auf den Oberschenkeln 21 aufliegt, wenn sich der Schließbügel 2 in der in den Fig. 7 und 8 dargestellten Schließstellung befindet. Diese Ausführungsform bietet im Vergleich zu den vorher beschriebenen Ausführungsformen der Fig. 1 und 2 sowie 5 und 6 den Vorteil, dass sich die Auflagefläche 12 individuell an jedes einzelne Bein anpasst, was bei den in Verbindung mit den Fig. 1,2 und 5, 6 dargestellten Ausführungsbeispielen nicht immer gegeben ist. So kann beispielsweise bei den Ausführungsformen gemäß Fig. 1 und 2 auf den beiden mittleren Sitzen eine unzureichende Anpassung an Personen erfolgen, wenn diese eine stark unterschiedliche Größe aufweisen. Bei der Ausführungsform gemäß Fig. 5 und 6, bei der der Schließbügel über die gesamte Breite verläuft, könnte dieses Problem noch verstärkt auftreten.At the last in the FIGS. 7 and 8 In the illustrated embodiment, the securing device 10 consists of elastically deformable elements 20, wherein the two outer seats are each assigned a single element 20, whereas the middle element 20 extends over the entire width of the two middle seats. Each element 20 consists for example of compressible plastic, z. B. foam, facing away from the cross bar 6 and the symbolically shown thighs 21 facing support surface 12 rests on the thighs 21 when the striker 2 in the in the FIGS. 7 and 8 shown closed position. This embodiment offers compared to the previously described embodiments of Fig. 1 and 2 and 5 and 6 have the advantage that the support surface 12 individually adapts to each individual leg, which in the in connection with the Fig. 1.2 and 5, 6 illustrated embodiments is not always given. For example, in the embodiments according to Fig. 1 and 2 on the two middle seats insufficient adaptation Persons are made if they have a very different size. In the embodiment according to FIGS. 5 and 6 , in which the striker extends over the entire width, this problem could occur even more.

Um dem abzuhelfen kann bei der Ausführungsform der Fig. 1 und 2 die Ausführung der Teleskopstangen bzw. deren Befestigung an den Sicherungsbügeln 11 bzw. am Querbügel 6 mit so viel seitlicher Bewegungsfreiheit ausgeführt sein, dass der Sicherungsbügel 11 bei Bedarf auch eine zum Querbügel 6 nicht parallele Stellung einnehmen kann, sodass er bei einer kleineren Person, die auf einem der beiden mittleren Sitze sitzt, weiter nach unten gehen kann, als bei einer daneben sitzenden größeren Person.To remedy this, in the embodiment of the Fig. 1 and 2 the execution of the telescopic rods or their attachment to the securing brackets 11 and be performed on the crossbar 6 with so much lateral freedom of movement that the securing bracket 11 can take a not parallel to the cross bar 6 position if necessary, so that he is in a smaller person, the sitting on one of the two middle seats, can go further down than with a larger person sitting next to it.

Sinngemäß kann bei der Ausführungsform gemäß Fig. 5 und 6 eine Schrägstellung des Sicherungsbügels 11 mit Bezug zum Querbügel 6 bzw. zu den Sitzflächen 3 z. B. dadurch gewährleistet sein, dass die Schenkel 18 gelenkig mit den Sicherungsbügeln 11 verbunden sind, wodurch eine Verdrehung der Sicherungseinrichtung 10 möglich wird.Analogously, in the embodiment according to FIGS. 5 and 6 an inclination of the securing bracket 11 with respect to the cross bar 6 and to the seats 3 z. B. be ensured by the fact that the legs 18 are pivotally connected to the securing brackets 11, whereby a rotation of the securing device 10 is possible.

Bei der Ausführungsform von Fig. 3 und 4 ist durch die Verwendung der Kniegelenkhebel 15, 16 automatisch gewährleistet, dass sich der Sicherungsbügel 11 mit Bezug zum Querbügel 6 bzw. den Sitzflächen 3 schrägstellen kann.In the embodiment of 3 and 4 is automatically ensured by the use of the knee lever 15, 16, that the securing bracket 11 with respect to the cross bar 6 and the seats 3 can tilt.

Zusätzlich könnte bei den Ausführungsformen gemäß Fig. 1 bis 6 noch vorgesehen sein, dass die Sicherungsbügel 11 mit elastisch deformierbaren Elementen ähnlich den Elementen 20 der Fig. 7 und 8 ausgestattet bzw. von diesen vollständig umschlossen werden, um eine zusätzliche flexible Anpassung zu ermöglichen.In addition, in the embodiments according to Fig. 1 to 6 be provided that the securing bracket 11 with elastically deformable elements similar to the elements 20 of the FIGS. 7 and 8 equipped or completely enclosed in order to allow additional flexible adaptation.
