Description

Die Erfindung betrifft einen Stuhl, insbesondere einen Bürostuhl.The invention relates to a chair, in particular an office chair.

Stühle mit Kopfstützen sind seit langem bekannt. Die Kopfstützen weisen in der Regel den Nachteil auf, dass die Höhenverstellung in der Regel kompliziert über Rastmechanismen erfolgt. Eine Neigungsverstellung ist in der Regel nicht möglich.Chairs with headrests have been known for a long time. The headrests generally have the disadvantage that the height adjustment is usually complicated via locking mechanisms. A tilt adjustment is usually not possible.

Aus der US 5,213,395 geht ein Stuhl hervor, der eine sowohl hinsichtlich der Höhe als auch hinsichtlich der Neigung in Stufen verstellbare Kopfstütze aufweist, wobei beide Verstellmechanismen nebeneinander angeordnet sind.From the US 5,213,395 goes out a chair, which has a both in height and in terms of inclination adjustable in stages headrest, both adjustment mechanisms are arranged side by side.

Der Erfindung liegt die Aufgabe zugrunde, einen Stuhl anzubieten, bei dem die Kopfstütze hinsichtlich der Höhe wie auch hinsichtlich der Neigung stufenlos verstellbar und kompakt aufgebaut ist.The invention has for its object to offer a chair in which the headrest is constructed in terms of height as well as in terms of inclination infinitely adjustable and compact.

Ein in Figur 1 dargestellter Stuhl 1, insbesondere ein Bürostuhl, weist ein Fußgestell 2 auf, das über Rollen 3 gegenüber dem Boden abgestützt ist. An dem Fußgestell 2 ist eine höhenverstellbare Stuhlsäule 4 angebracht, an deren oberem Ende ein Sitzträger 5 lösbar befestigt ist, auf dem wiederum ein gepolsterter Sitz 6 angebracht ist. Am hinteren Ende des Sitzträgers 5 ist ein sich im wesentlichen nach oben erstreckender Rückenlehnen-Träger 7 angebracht, an dem eine gepolsterte Rückenlehne 8 befestigt ist. Am oberen Ende des Rückenlehnen-Trägers 7 ist ein Kopfstützen-Träger 9 angebracht, an dem eine Kopfstütze 10 befestigt ist.A chair 1 shown in FIG. 1, in particular an office chair, has a base frame 2 which is supported by rollers 3 with respect to the floor. On the pedestal 2, a height-adjustable chair column 4 is attached to the upper end of a seat support 5 is releasably attached, on which in turn a padded seat 6 is mounted. At the rear end of the seat support 5, a substantially upwardly extending backrest support 7 is attached to which a padded backrest 8 is attached. At the upper end of the backrest support 7, a headrest support 9 is attached, to which a headrest 10 is attached.

Im folgenden wird unter Bezugnahme auf die Figuren 2 bis 5 der Aufbau der Kopfstütze 10 genauer beschrieben. Der Rückenlehnen-Träger 7 weist zwei im wesentlichen vertikal und parallel zueinander verlaufende, sich bis zum oberen Ende der Rückenlehne 8 erstreckende Holme 11 auf, die an ihrem oberen Ende jeweils in einen Kopfstützen-Träger-Bügel 12 übergehen. Die Bügel 12 gehen an ihrem oberen Ende kontinuierlich in ein sich im Durchmesser verjüngendes, horizontal verlaufendes Wellen-Befestigungs-Preßlager 13 über. Die freien Enden 14 der Lager 13 sind einander zugewandt. Die Kopfstütze 10 ist gegenüber den Bügeln 12 abgestützt und mit diesen verbunden.In the following, the construction of the headrest 10 will be described in more detail with reference to Figs. The backrest support 7 has two substantially vertically and parallel to each other, up to the upper end of the backrest 8 extending spars 11, which merge at its upper end respectively in a headrest support bracket 12. The bracket 12 go at its upper end continuously in a tapered in diameter, horizontally extending shaft-mounting press bearing 13 via. The free ends 14 of the bearings 13 face each other. The headrest 10 is supported against the brackets 12 and connected thereto.

Die Kopfstütze 10 weist einen Rahmen 15 auf, der durch zwei parallel zueinander verlaufende Paare von Schienen 16 sowie zwei diese verbindende Querholme 17 gebildet wird. Die Schienen 16 sind, wie in Figur 5 erkennbar, gekrümmt ausgebildet und bestehen beispielsweise aus FederstahlBlech. Die Schienen 16 eines Schienenpaares verlaufen parallel übereinander. Die Querholme 17 haben jeweils die Form eines langgestreckten Quaders, der endseitig über die Verbindungspunkte 18 mit den Schienen 16 hervorsteht. Eine Welle 19 ist zwischen den beiden Paaren der Schienen 16 hindurchgeführt und weist an ihren beiden Enden Zapfen 20 auf, die in entsprechenden Ausnehmungen 21 des Lagers 13 mit Preßsitz festgelegt sind. Die Welle 19 ist somit im wesentlichen drehfest gegenüber den Lagern 13 befestigt. Der Rahmen 15 ist mit der Welle 19 über zwei Paare von Reib-Führungs-Schuhen 22 verbunden. Die Schuhe 22 weisen mittig jeweils eine Bohrung 23 auf, durch die die Welle 19 geführt ist. Die Schuhe 22 weisen auf einander zugewandten Seiten jeweils zwei Nuten 24 auf, deren Tiefe geringfügig kleiner ist als die halbe Breite der Schienen 16. Jeweils zwei Schuhe 22 sind durch zwei Schrauben 25 miteinander zu einem Paar 26 verbunden. Die insgesamt vier Nuten 24 eines Paares 26 umschließen - zwei Kanäle bildend - die beiden Schienen 26. Durch die Schrauben 25 ist die Reibung zwischen den Schuhen 22 und den Schienen 16 einstellbar. Die Paare 26 sind auf den Schienen 16 gegen eine Gegenkraft verschiebbar und bilden eine Höhenverstell-Einrichtung für die Kopfstütze 10. Die Reibung zwischen den Schienen 16 und den beiden Paaren 26 ist so eingestellt, dass die Kopfstütze 10 in Bezug auf die nach außen abgestützte Welle 19 ohne äußere Krafteinwirkung in jeder beliebigen voreingestellten Position ortsfest verharrt.The headrest 10 has a frame 15 which is formed by two mutually parallel pairs of rails 16 and two transverse bars 17 connecting them. The rails 16 are, as can be seen in Figure 5, curved and made for example of spring steel sheet. The rails 16 of a pair of rails run parallel to each other. The transverse bars 17 each have the shape of an elongated cuboid which protrudes beyond the connecting points 18 with the rails 16 end. A shaft 19 is passed between the two pairs of rails 16 and has at its two ends pins 20 which are fixed in corresponding recesses 21 of the bearing 13 with a press fit. The shaft 19 is thus fixed substantially rotationally fixed relative to the bearings 13. The frame 15 is connected to the shaft 19 via two pairs of friction-guiding shoes 22. The shoes 22 each have a bore 23 centrally through which the shaft 19 is guided. The shoes 22 have on facing sides in each case two grooves 24 whose depth is slightly smaller than half the width of the rails 16. In each case two shoes 22 are connected by two screws 25 together to form a pair 26. The total of four grooves 24 of a pair 26 enclose - forming two channels - the two rails 26. The screws 25, the friction between the shoes 22 and the rails 16 is adjustable. The pairs 26 are slidable on the rails 16 against a counterforce and form a height adjustment device for the headrest 10. The friction between the rails 16 and the two pairs 26 is adjusted so that the headrest 10 with respect to the outwardly supported shaft 19 stationary without external force in any preset position.

Die Schuhe 22 weisen auf ihren inneren Stirnseiten 27 im Bereich der Bohrung 23 eine konische Erweiterung 28 der Bohrung 23 auf. Zwischen der Welle 19 einerseits und den beiden Schuhen 22 eines Paares 26 andererseits entsteht hierdurch eine ringförmige Kammer, in der ein Gummiring 29 festgelegt ist. Durch die konisch verlaufenden Flächen der Kammer im Bereich der Erweiterung 28 wird der Gummiring 29 beim Verschrauben zweier Schuhe 22 an die Welle 19 angedrückt, wodurch eine vorbestimmbare Reibungskraft zwischen der Welle 19 und dem Rahmen 15 einstellbar ist. Da die Welle 19 drehfest gegenüber dem Lager 13 befestigt ist, kann die Kopfstütze 10 nur gegen eine Kraft um die Welle 19 verschwenkt werden. Ohne äußere Krafteinwirkung verharrt die Kopfstütze 10 in jeder voreingestellten Neigungsposition mit einem Neigungswinkel a gegenüber der Vertikalen. Die Welle 19 bildet insofern zusammen mit den Schuhen 22 eine Neigungs-Verstelleinrichtung zur Verstellung des Neigungswinkels a der Kopfstütze 10.The shoes 22 have on their inner end faces 27 in the region of the bore 23 a conical widening 28 of the bore 23. Between the shaft 19 on the one hand and the two shoes 22 of a pair 26 on the other hand, this results in an annular chamber in which a rubber ring 29 is fixed. Due to the conical surfaces of the chamber in the region of the extension 28 of the rubber ring 29 is pressed when screwing two shoes 22 to the shaft 19, whereby a predeterminable Frictional force between the shaft 19 and the frame 15 is adjustable. Since the shaft 19 is secured against rotation relative to the bearing 13, the headrest 10 can be pivoted against the shaft 19 only against a force. Without external force the headrest 10 remains in each preset inclination position with an inclination angle a relative to the vertical. The shaft 19 forms so far together with the shoes 22 a tilt adjustment for adjusting the inclination angle a of the headrest 10th

Der Rahmen 15 ist durch eine mehrteilige beispielsweise aus Holz bestehende Verkleidung verkleidet. Auf der Oberseite des oberen Querholms 17 und der Unterseite des unteren Querholms 17 sind zwei halbzylindrische Profile 30 befestigt. An der Vorder- und Rückseite ist jeweils eine gekrümmte Deckplatte 31 befestigt. Die Deckplatten 31 weisen entlang des von den Schuhen 22 bei der Höhenverstellung überstrichenen Bereichs rechteckige Ausnehmungen 32 auf, in die Teile der Schuhe 22 ragen. Auf diese Weise ist eine möglichst kompakte Ausbildung der Kopfstütze 10 möglich, da die Gesamtdicke K der Verkleidung der Kopfstütze 10 nur geringfügig größer ist als die Dicke S der Schuhe 22. An den Stirnseiten des Rahmens 15 sind zwei gekrümmte Stirnplatten 33 mit gekrümmten Langlöchern 34 befestigt, wobei die Welle 19 in dem Langloch 34 verschoben wird. Die in Figur 2 nur mit der Verkleidung dargestellte Kopfstütze 10 wird abschließend, wie in Figur 1 dargestellt, beispielsweise mit Leder oder Stoff bespannt.The frame 15 is clad by a multi-part, for example made of wood panel. On the top of the upper cross member 17 and the underside of the lower cross member 17, two semi-cylindrical profiles 30 are attached. At the front and back, a curved cover plate 31 is attached in each case. The cover plates 31 have along the swept by the shoes 22 in the height adjustment area rectangular recesses 32 in the parts of the shoes 22 protrude. In this way, the most compact possible design of the headrest 10 is possible because the total thickness K of the panel of the headrest 10 is only slightly larger than the thickness S of the shoes 22. At the end faces of the frame 15, two curved end plates 33 are secured with curved slots 34 , wherein the shaft 19 is displaced in the slot 34. The illustrated in Figure 2 only with the panel headrest 10 is finally, as shown in Figure 1, for example, covered with leather or fabric.

Im folgenden wird die Funktionsweise der Kopfstütze näher beschrieben. Um die Höhe der Kopfstütze 10 zu verändern, übt der Benutzer des Stuhles 1 auf diese von oben oder von unten eine Kraft aus. Ist die Kraft groß genug, um eine vorgegebene Reibungskraft zu überwinden, so werden die Schienen 16 in den Nuten 24 der Schuhe 22 verschoben, wodurch sich die Höhe der Kopfstütze 10 ändert. Durch die zwischen den Schienen 16 und den Schuhen 22 wirkende Reibung ist die Kopfstütze 10 in der neueingestellten Endposition stabil und rutscht nicht wieder nach unten. Soll der Neigungswinkel a der Kopfstütze verstellt werden, so verschwenkt der Benutzer die Kopfstütze um die Welle 19. Da die Zapfen 20 im Lager 13 drehfest befestigt sind, findet eine Verschwenkung der Schuhe 22 relativ zur Welle 19 statt. Aufgrund der zwischen der Wand der Bohrung 23 und der Welle 19 bestehenden Reibung sowie der durch den Gummiring 29 zwischen den Schuhen 22 und der Welle 19 eingestellten Reibung, ist zur Verschwenkung der Kopfstütze 10 um die Welle 19 ein Mindest-Drehmoment erforderlich. Wird dieses überschritten, so findet eine Verschwenkung der Kopfstütze 10 statt. Wird kein äußeres Drehmoment auf die Kopfstütze 10 ausgeübt, so bleibt diese in der eingestellten Endposition ortsfest.The following describes the operation of the headrest closer. In order to change the height of the headrest 10, the user of the chair 1 exerts a force on them from above or from below. If the force is large enough to overcome a given friction force, then the Rails 16 are displaced in the grooves 24 of the shoes 22, whereby the height of the headrest 10 changes. By acting between the rails 16 and the shoes 22 friction headrest 10 is stable in the newly set end position and does not slip back down. If the inclination angle a of the headrest is to be adjusted, then the user pivots the headrest about the shaft 19. Since the pins 20 are fastened rotationally fixed in the bearing 13, the shoes 22 are pivoted relative to the shaft 19. Due to the existing between the wall of the bore 23 and the shaft 19 friction and the set by the rubber ring 29 between the shoes 22 and the shaft 19 friction, a minimum torque is required for pivoting the headrest 10 to the shaft 19. If this is exceeded, a pivoting of the headrest 10 takes place. If no external torque is exerted on the headrest 10, it remains stationary in the set end position.

Durch die Krümmung der Kopfstütze 10 nach hinten, paßt sich diese der Kontur von Hinterkopf und Genick eines sich nach hinten lehnenden Menschen an. Besonders vorteilhaft ist, dass sich der Neigungswinkel a der Kopfstütze 10 beim Nach-Hinten-Lehnen automatisch einstellen kann. Durch die Höhenverstellbarkeit der Kopfstütze ist sichergestellt, dass der obere Teil des Genicks eines Benutzers ungefähr in der Höhe der Welle 19 liegt und die Verschwenkbarkeit der Kopfstütze 10 im wesentlichen der des menschlichen Genicks entspricht. Hierdurch wird die Kopfstütze 10 als besonders komfortabel empfunden. Besonders vorteilhaft ist, dass die Höhe der Kopfstütze 10 und deren Neigungswinkel gleichzeitig und stufenlos verstellt werden können. Außerdem besteht die Möglichkeit, durch eine um mehr als 360° drehbare Kopfstütze 10 für den Kopf des Benutzers eine konvexe oder konkave Kopfanlagefläche zu nutzen. Bei der in den Figuren 1 und 2 dargestellten Position der Kopfstütze 10 ist die Kopfanlagefläche vom Kopf aus gesehen konkav. Durch eine Drehung um 180° um die Welle 19 kann die gegenüberliegende Kopfanlagefläche genutzt werden.Due to the curvature of the headrest 10 to the rear, this adapts to the contour of the back of the head and neck of a leaning backwards man. It is particularly advantageous that the inclination angle a of the headrest 10 can adjust automatically when back-to-back. The height adjustability of the headrest ensures that the upper part of the neck of a user is approximately at the height of the shaft 19 and the pivotability of the headrest 10 substantially corresponds to that of the human genius. As a result, the headrest 10 is perceived as particularly comfortable. It is particularly advantageous that the height of the headrest 10 and its inclination angle can be adjusted simultaneously and continuously. In addition, it is possible to use a convex or concave head contact surface by means of a headrest 10 which can be rotated by more than 360 ° for the head of the user. When in the figures 1 and 2 illustrated position of the headrest 10 is the head contact surface seen from the head concave. By a rotation through 180 ° about the shaft 19, the opposite head contact surface can be used.
