Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung betrifft das Gebiet der Sitzmöbel, insbesondere eine Nackenstütze für einen Stuhl für den Bürobereich.The invention relates to the field of seating, in particular a neck support for a chair for the office area.

STAND DER TECHNIKSTATE OF THE ART

Insbesondere im Bürobereich ist es wichtig, dass der Benutzer eines Stuhles die Möglichkeit hat, sich wiederholt von der während der Arbeit eingenommenen Sitzposition zu entspannen. Dazu ist es nicht nur notwendig, den Winkel zwischen Ober- und Unterkörper duch Zurücklehnen zu öffnen, sondern auch dem Kopf bzw. Nacken eine Ruhemöglichkeit zu geben. Dazu dient die Nackenstütze.In the office area in particular, it is important that the user of a chair uses the Possibility to repeat yourself from the one taken during work Relax sitting position. It is not only necessary to do this, the angle open between upper and lower body by leaning back, but also to give the head or neck a rest. This is what the Headrest.

Eine Nackenstütze für einen Bürostuhl ist zum Beispiel bekannt aus EP 1'192'880 A2. Bei dieser Nackenstütze ist ein Haltestab an der Rückseite der Stuhllehne gelenkig angebunden, und auf diesem Haltestab gleitet eine Führungshülse, an deren oberem Ende das Kopfpolster befestigt ist. Haltestab und Führungshülse sind kreisbogenförmig ausgebildet. Der Abstand des Kopfpolsters zum Kopf bzw. Nacken des Benutzers wird hauptsächlich durch ein Schwenken des Haltestabes um das Gelenklager an der Rückenlehne verändert. Zusätzlich erfolgt eine solche Veränderung aber auch bei einer Höhenverstellung des Kopfpolsters durch Gleiten der Führungshülse auf dem Haltestab wegen des kreisbogenförmigen Bewegungsweges.A neck rest for an office chair is known from, for example EP 1'192'880 A2. This neck support has a holding rod on the back of the The back of the chair is hinged, and one slides on this support bar Guide sleeve, on the upper end of which the head cushion is attached. retaining bar and the guide sleeve are designed in the shape of a circular arc. The distance of the Head cushion to the head or neck of the user is mainly by a Swiveled the support rod around the spherical bearing on the backrest changed. In addition, such a change also occurs with a height adjustment of the head cushion by sliding the guide sleeve on the holding rod because of the circular path of movement.

Die bekannte Konstruktion hat sich in der Praxis zwar bewährt, vermag jedoch ästhetisch nicht ganz zu befriedigen, da die Anbringung des Gelenklagers an der Rückenlehne das einheitliche Erscheinungsbild derselben stört. Ferner ist auch der Herstellaufwand nicht unbedeutend, und ist die Einstellung der Entfernung des Kopfpolsters vom Kopf des Benutzers durch die auf einer Kreisbahn erfolgende Höhenverstellung nicht hinreichend flexibel.The known construction has proven itself in practice, but is capable aesthetically not entirely satisfactory, since the attachment of the spherical bearing to the Backrest disturbs the uniform appearance of the same. It is also the manufacturing effort is not insignificant, and is the adjustment of the distance of the head cushion from the user's head through on a circular path height adjustment not sufficiently flexible.

Eine andere Nackenstütze ist bekannt aus EP 1'186'257 A2. Bei dieser Nackenstütze ist ein kreisbogenförmiger Haltestab an der Oberkante der Rückenlehne angelenkt, auf dem eine gleichfalls kreisbogenförmige Führungshülse, die in das Kopfpolster integriert ist, auf und ab gleiten kann.Another neck support is known from EP 1'186'257 A2. At this Neck support is an arc-shaped support rod at the top of the Articulated backrest, on which a likewise circular arc Guide sleeve, which is integrated in the head cushion, can slide up and down.

Auch diese Nackenstütze hat sich an sich bewährt, weist aber, wie die erstgenannte, den Nachteil auf, dass die Entfernung des Kopfpolsters vom Kopf des Benutzers nicht in einem optimal großen Bereich einstellbar ist.This neck support has also proven itself, but shows how the former, the disadvantage of that the removal of the head cushion from the head the user cannot be set in an optimally large range.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Es ist daher die Aufgabe der Erfindung, eine Nackenstütze für einen Stuhl, insbesondere einen Bürostuhl, derart weiterzuentwickeln, dass sie einerseits ästhetisch ansprechend diskret und ohne übermäßigen Herstell- und Montieraufwand an der Rückenlehne angebracht werden kann, andererseits aber dennoch einen großen Einstellbereich für den Kopf des Benutzers aufweist. Insbesondere soll die Nackenstütze diese Eigenschaften auch bei der Montage an einer höhenverstellbaren und neigbaren Rückenlehne aufweisen.It is therefore the object of the invention to provide a neck support for a chair, in particular an office chair, to be developed in such a way that on the one hand aesthetically pleasing discreet and without excessive manufacturing and Assembly effort can be attached to the backrest, on the other hand nevertheless has a large adjustment range for the user's head. In particular, the neck support should also have these properties during assembly have on a height-adjustable and reclining backrest.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 und der Unteransprüche gelöst. This object is achieved by the features of claim 1 and Subclaims resolved.

Der Kern der Erfindung ist die Idee, einen geraden Haltestab gelenkig an der Oberkante der Rückenlehne anzubinden, und auf diesem verschiebbar eine gerade Führungshülse vorzusehen, an deren oberem Ende das Kopfpolster angelenkt ist. Der Schwenkbereich des Haltestabes soll von der Richtung der Lehne aus etwa 35° nach vom betragen, der des Kopfpolsters etwa 40°. Basierend auf diesem Grundkonzept kann die Nackenstütze dann im technischen Detail so ausgeführt werden, dass sie ästhetisch ansprechend und ohne großen Aufwand herstellbar und montierbar ist, und insbesondere zusammen mit einer in der Höhe und Neigung verstellbaren Lehne einen optimalen Einstellbereich für den Benutzer ergibt.The essence of the invention is the idea of articulating a straight holding rod on the Tie the top edge of the backrest, and slidable on this provide straight guide sleeve, at the upper end of which the head cushion is articulated. The pivoting range of the support rod should be from the direction of the Lean from approximately 35 ° to the front, the head cushion approximately 40 °. Based on this basic concept, the neck support can then be used in the technical area Detail can be designed so that it is aesthetically pleasing and without great Effort can be produced and assembled, and in particular together with an in the height and inclination adjustable backrest an optimal adjustment range for gives the user.

    • WEGE ZUR AUSFÜHRUNG DER ERFINDUNGWAYS OF CARRYING OUT THE INVENTION

    In Fig. 1 ist ein Ausschnitt aus dem oberen mittleren Teil der Rückenlehne 1 eines Bürodrehstuhles dargestellt, an welchem über ein unteres Gelenklager 3 ein gerader Haltestab 2 angebunden ist. Auf diesem Haltestab 2 ist verschiebbar die Führungshülse 4 angeordnet, die an ihrem oberen Ende das obere Gelenklager 5 aufweist. An diesem Gelenklager 5 ist mit seinem oberen Teil das Kopfpolster 6 angelenkt.1 shows a section of the upper middle part of the backrest 1 of an office swivel chair, on which a lower spherical bearing 3 a straight support bar 2 is connected. On this support bar 2 is slidable the guide sleeve 4 arranged, the upper at its upper end Spherical bearing 5 has. At this spherical bearing 5 is with its upper part Head cushion 6 articulated.

    Es sind vier verschiedene mögliche Positionen des Kopfpolsters 6 dargestellt:Four different possible positions of the head cushion 6 are shown:

    In der ersten Position verlaufen Haltestab 2 und Führungshülse 4 in Verlängerung der Rückenlehne 1, also im Bild senkrecht nach oben, wobei die Führungshülse 4 ihre tiefste Stellung einnimmt. In der zweiten Position steht die Führungshülse 4 gleichfalls senkrecht, aber in ihrer höchsten Stellung.In the first position, the holding rod 2 and the guide sleeve 4 extend the backrest 1, that is to say vertically upwards in the figure, the guide sleeve 4 occupies its lowest position. The guide sleeve 4 is in the second position also vertical, but in its highest position.

    In der dritten und vierten Position ist die Führungshülse 4 nach vorn geneigt, und das Kopfpolster 6 befindet sich einmal in der tiefsten und einmal in der höchsten Stellung.In the third and fourth positions, the guide sleeve 4 is inclined forward, and the head cushion 6 is once in the deepest and once in the highest Position.

    Erfindungsgemäß soll der Schwenkbereich um das untere Gelenklager 3 bis etwa 35°, der um das obere Gelenklager 5 bis etwa 40° betragen. Die Länge des Auszugs der Führungshülse 4 auf dem Haltestab 2 beträgt etwa 70 mm. Diese kurze Auszugslänge ist durch die Anbringung der Nackenstütze an einer nicht nur in der Neigung, sondern auch in der Höhe verstellbaren Rückenlehne möglich: die grobe Einstellung kann dann mit der Lehne des Stuhles erfolgen, und die Verstellbarkeit der Nackenstütze dient nur der Feineinstellung. Insgesamt ergibt sich damit ein beachtliches Einstellspektrum.According to the invention, the swivel range around the lower spherical bearing 3 should be approximately 35 °, which amount to about 40 ° around the upper spherical bearing. The length of the Extraction of the guide sleeve 4 on the holding rod 2 is approximately 70 mm. This Short extension length is not only due to the attachment of the neck support to one incline, but also height-adjustable backrest possible: the rough adjustment can then be made with the back of the chair, and the Adjustment of the neck support is only for fine adjustment. Total results a remarkable range of settings.

    Aus Fig.2 ist ersichtlich, dass der Haltestab 2 unten einen Zylinder 7 angeformt hat. Dieser Zylinder 7 liegt im montierten Zustand zwischen dem Zylinder 8 und dem Zylinder 9, die beide am oberen Ende des Lagerfußes 10 angeformt sind.It can be seen from FIG. 2 that the holding rod 2 forms a cylinder 7 at the bottom Has. This cylinder 7 is in the assembled state between the cylinder 8 and the cylinder 9, both of which are molded onto the upper end of the bearing base 10.

    Zur Montage werden die beiden Kulissensteine 13 zusammen mit der Spiralfeder 28 in den Zylinder 7 eingesetzt und gegeneinander gedrückt. Dann wird der Zylinder 7 zwischen die Zylinder 8 und 9 gebracht und der Druck auf die Feder 28 weggenommen. Dadurch treten die Kulissensteine 13 in die Zylinder 8 und 9 ein, und der Haltestab 2 wird damit gelenkig gelagert. Wie insbesondere auch aus Fig. 4 Schnitten B-B und C-C ersichtlich, weist der Zylinder 7 am Haltestab 2 eine derartige innere Formgebung auf, dass sich die Kulissensteine 13 nicht drehen können. Im Zylinder 8 bzw. 9 ist die Formgebung jedoch derart, dass die Kulissensteine 13 zwischen den Anschlägen 14 einen Drehraum haben, der die Verschwenkung des Haltestabes 2 ermöglicht.For assembly, the two sliding blocks 13 together with the spiral spring 28 inserted into the cylinder 7 and pressed against each other. Then the Cylinder 7 placed between cylinders 8 and 9 and the pressure on spring 28 taken away. As a result, the sliding blocks 13 enter the cylinders 8 and 9, and the holding rod 2 is thus articulated. As especially from 4 sections B-B and C-C can be seen, the cylinder 7 on the holding rod 2 has one such an internal shape that the sliding blocks 13 do not rotate can. In the cylinder 8 or 9, however, the shape is such that the Slide blocks 13 have a turning space between the stops 14, which the Pivoting the holding rod 2 allows.

    Damit der Haltestab 2 in jeder eingestellten Schwenkposition feststeht, sind in den Zylindern 8 und 9 Tellerfedern 15 vorgesehen, die mittels einer Spannschraube 16 unter Spannung gesetzt werden, sodass der Haltestab 2 durch die damit erzeugte Reibung gehalten wird.So that the holding rod 2 is fixed in every set swivel position, in the cylinders 8 and 9 disc springs 15 provided by means of a Tensioning screw 16 is put under tension so that the holding rod 2 is held by the friction generated with it.

    Der Aufbau des oberen Gelenklagers 5 ist prinzipiell identisch mit dem geschilderten Aufbau des unteren Gelenklagers 3. Es wird deshalb nicht noch einmal eigens beschrieben, und die entsprechenden Einzelteile tragen keine eigenen Bezugszeichen. Anders ist dieses Lager jedoch insofern, als die den Zylindern 8 und 9 entsprechenden Zylinder an der Lasche 26 angebracht sind, die mittels der Schrauben 27 am Rahmen 23 des Kopfpolsters 6 befestigt werden.The structure of the upper spherical bearing 5 is basically identical to that described construction of the lower spherical bearing 3. It is therefore not yet once described, and the corresponding parts do not have any own reference numerals. This camp is different, however, in that the Cylinders 8 and 9 corresponding cylinders are attached to the tab 26, which are fastened to the frame 23 of the head cushion 6 by means of the screws 27 become.

    Die Bewegung der Führungshülse 4 auf dem Haltestab 2 wird durch die Gleitringe 21 stabilisiert. Diese weisen Gleitnoppen 24 auf, und greifen nach der Montage in die Kerben 22 des Haltestabes 2 ein. Der Clip 20 gleitet in dem Führungsschlitz 19 und fasst mit seiner Nase in die Ausnehmung 25 der Führungshülse 4, und dient somit als Auszugssicherung für die auf dem Haltestab 2 gleitende Führungshülse 4.The movement of the guide sleeve 4 on the holding rod 2 is due to the slide rings 21 stabilized. These have sliding knobs 24, and engage in after assembly the notches 22 of the holding rod 2. The clip 20 slides in the guide slot 19 and grips with its nose into the recess 25 of the guide sleeve 4, and thus serves as a pull-out protection for the sliding on the holding rod 2 Guide sleeve 4.

    In Fig.2 ist gut ersichtlich, dass das Kopfpolster 6 auf einem Rahmen 23 gehalten wird. Vorteilhafterweise wird der vorzugsweise aus Kunststoff bestehende Rahmen 23 zur Erzeugung des Kopfpolsters 6 in Polyurethan (PUR) eingeschäumt. Dadurch ist das Kopfpolster 6 in seiner Mitte weich und erzeugt für den Benutzer ein erhöhtes Komfortgefühl. In Figure 2 it can be clearly seen that the head cushion 6 is held on a frame 23 becomes. Advantageously, it is preferably made of plastic Frame 23 for producing the head cushion 6 in polyurethane (PUR) foamed. As a result, the head cushion 6 is soft and produced in the middle for the user an increased feeling of comfort.

    In Fig. 3 ist die erfindungsgemäße Nackenstütze im montierten Zustand gezeigt. Die schon beschriebenen Teile sind auch im montierten Zustand ohne weiteres verständlich und werden deshalb nicht noch einmal beschrieben.In Fig. 3 the neck support according to the invention is shown in the assembled state. The parts already described are also easy to assemble understandable and are therefore not described again.

    Lediglich die Befestigung des unteren Gelenklagers 3 in der Lehne 1 des Stuhles wird daher noch beschrieben:Only the attachment of the lower spherical bearing 3 in the back 1 of the chair is therefore still described:

    Wie ersichtlich, steckt der Lagerfuß 10 schwertartig im Schacht 11 der Lehnenplatte 12. Wie auch aus Fig.2 ersichtlich, weist der Lagerfuß unten eine Rastnase 17 auf, die in die Ausnehmung 18 der Lehnenplatte 12 einrastet und den Lagerfuß 10 damit fest verankert. Die Montage der Nackenstütze an der Oberkante der Lehne 1 ist dadurch extrem einfach, aber dennoch sicher.As can be seen, the bearing base 10 is in the shaft 11 of the sword Backrest plate 12. As can also be seen from FIG. 2, the bottom of the bearing has one Latch 17, which engages in the recess 18 of the backrest plate 12 and the bearing base 10 thus firmly anchored. The mounting of the headrest on the The top edge of the backrest 1 is therefore extremely simple, but nevertheless safe.

    In Fig.4 sind nochmals die Einzelheiten des unteren Lagers 3 dargestellt, die - wie schon gesagt - auch denen des oberen Lagers 5 entsprechen. Besonders die Funktion der Kulissensteine 13 in den Zylindern 7, 8, und 9 ist aus Fig.4 gut verständlich.In Figure 4 the details of the lower bearing 3 are shown again, the - as already said - also correspond to those of the upper bearing 5. Especially the function of the sliding blocks 13 in the cylinders 7, 8 and 9 is good from Fig.4 understandable.

    Zusammenfassend ist festzustellen, dass die erfindungsgemäße Nackenstütze durch ihre lineare Höhenverstellung und ihre Schwenkbarkeit um zwei Lager ein Höchstmaß an Komfort für den Benutzer ergibt, aber dennoch mit verhältnismäßig geringem Aufwand herstellbar und montierbar ist. In summary, it should be noted that the neck support according to the invention due to their linear height adjustment and their swiveling by two bearings Provides maximum comfort for the user, but still with is relatively easy to manufacture and assemble.
