Description

Die Erfindung betrifft eine Vorrichtung zur Bestimmung (Messen) der Abmessungen von Sitzmöbeln (Stühlen, Sesseln) gemäß dem Oberbegriff des Anspruchs 1 (US-A-3 112 137).The invention relates to a device for determining (measuring) the dimensions of seating (chairs, armchairs) according to the preamble of claim 1 (US-A-3 112 137).

Die gattungsbildende US-A-3 112 137 befaßt sich mit dem Problem, Sitzmöbel individuell an Körpergröße, Körperhaltung etc. eines (potentiellen) Benutzers anzupassen. Dazu findet bei der US-A-3 112 137 ein einstellbarer Meßstuhl Verwendung. Der aus einem fachwerkartig zusammengesetzten Rahmen gebildete Meßstuhl ist auf einer hydraulischen Hubeinrichtung angeordnet und mit dieser fest verbunden. Durch diese feste Verbindung des Meßstuhls mit der Hubeinrichtung läßt sich zur Messung kein individuelles Sitzmöbel verwenden, das im wesentlichen dem zu vermessenden Stuhl entspricht. Die Messung ist dadurch ungenau und somit beeinträchtigt. Es kann sogar vorkommen, daß ein nach den auf dem rahmenartigen Meßstuhl gemäß der US-A-3 112 137 ermittelten Daten gefertigtes Sitzmöbel nicht den individuellen Maßen des Benutzers entspricht.The generic US-A-3 112 137 deals with the problem of individually adapting seating furniture to the body size, posture, etc. of a (potential) user. For this purpose, an adjustable measuring chair is used in US-A-3 112 137. The measuring chair formed from a framework composed of a framework is arranged on a hydraulic lifting device and firmly connected to it. This fixed connection between the measuring chair and the lifting device means that no individual seating furniture can be used for the measurement, which essentially corresponds to the chair to be measured. As a result, the measurement is inaccurate and therefore impaired. It can even happen that a seat made according to the data determined on the frame-like measuring chair according to US-A-3 112 137 does not correspond to the individual dimensions of the user.

Der Erfindung liegt demnach die Aufgabe zugrunde, eine Vorrichtung der gattungsbildenden Art dahingehend weiterzuentwickeln, daß sich zur Messung ein Sitzmöbel verwenden läßt, das dem vom zukünftigen (potentiellen) Benutzer gewählten im wesentlichen entspricht.The invention is therefore based on the object of further developing a device of the generic type in such a way that seating can be used for the measurement, which essentially corresponds to that chosen by the future (potential) user.

Zur Lösung dieser Aufgabe weist die erfindungsgemäße Vorrichtung die Merkmale des Anspruchs 1 auf. Dadurch wird erreicht, daß zur zuverlässigen Ermittlung der Abmessungen eines individuell in Abhängigkeit vom späteren Benutzer anzufertigenden Sitzmöbels ein Sitzmöbel (Sessel, Stuhl oder dergleichen) in der Art des anzufertigenden Sitzmöbels so verstellt werden kann, daß zur Messung der zukünftige Benutzer eine optimale bzw. gesundheitlich sinnvolle Sitzhaltung hierauf einnimmt.To achieve this object, the device according to the invention has the features of claim 1. The result of this is that, in order to reliably determine the dimensions of a piece of seating furniture which is to be produced individually as a function of the later user, a piece of seating furniture (armchair, chair or the like) can be adjusted in the manner of the seating furniture to be produced in such a way that future users can measure it optimally or in terms of health sensible posture.

Zweckmäßigerweise wird das Sitzmöbel der herzustellenden Art auf eine Hubeinrichtung gestellt. Die Hubeinrichtung ist zu diesem Zweck aus seitlichen Teilplattformen gebildet, auf denen die Stuhlbeine ruhen. Durch gemeinsames Auf- und Abbewegen der Teilplattformen wird der Stuhl bzw. der Sessel zur Ermittlung der zutreffenden Sitzhöhe angehoben oder gesenkt.The seating of the type to be manufactured is expediently placed on a lifting device. For this purpose, the lifting device is formed from lateral sub-platforms on which the chair legs rest. By moving the partial platforms up and down, the chair or armchair is raised or lowered to determine the applicable seat height.

Gemäß einer Weiterbildung der erfindungsgemäßen Vorrichtung werden die Teilplattformen motorisch betrieben zum stufenlosen Auf- und Abbewegen des Sitzmöbels. Auf diese Weise kann in einfacher Weise die optimale Sitzhöhe des Benutzers im anzufertigenden Sitzmöbel bestimmt werden. Anhand einer Skala kann das zutreffende (Höhen-)Maß einfach festgestellt werden.According to a development of the device according to the invention, the sub-platforms are operated by motor for the stepless movement of the seating furniture up and down. In this way, the optimal seat height of the user in the seating furniture to be produced can be determined in a simple manner. The applicable (height) measurement can be easily determined using a scale.

Weitere Unteransprüche beziehen sich auf konstruktive Ausbildungen der Hubeinrichtung sowie der Teilplattformen.Further subclaims relate to the design of the lifting device and the sub-platforms.

Bei den gezeigten Ausführungsbeispielen geht es zunächst um Einrichtungen und Hilfsmittel für die Feststellung von Abmessungen und sonstige Konstruktionseinzelheiten von Sitzmöbeln. Dabei wird gemäß vorliegendem Ausführungsbeispiel so vorgegangen, daß die relevanten Körpermaße durch Verändern eines "Meßsessels" unter Anpassung an die individuellen Bedürfnisse des Benutzers festgestellt werden.The exemplary embodiments shown are initially concerned with devices and aids for determining dimensions and other construction details of seating furniture. The procedure according to the present exemplary embodiment is such that the relevant body dimensions are determined by changing a "measuring chair" while adapting to the individual needs of the user.

In Fig. 1 ist ein Sessel 20 zu diesem Zweck auf einer Hubeinrichtung 21 angeordnet. Der Sessel 20 entspricht vorzugsweise einem konventionellen Sessel bzw. einem solchen mit Verstellmöglichkeiten für die Sitzhaltung beeinflussenden Konstruktionsteilen.1, an armchair 20 is arranged on a lifting device 21 for this purpose. The armchair 20 preferably corresponds to a conventional armchair or one of the structural parts influencing the adjustment of the posture.

Die Hubeinrichtung 21 ist im vorliegenden Falle im Grundriß U-förmig ausgebildet (Fig. 2) mit einem quergerichteten Motorgehäuse 22 und daran nach Art von Schenkeln anschließenden Hubgehäusen 23 und 24. Im Motorgehäuse 22 ist ein (elektrischer) Antriebsmotor 25 etwa mittig untergebracht. Von diesem wird der Hubantrieb auf die beiden Hubgehäuse 23 und 24 bzw. auf eine innerhalb derselben angeordnete Hubmechanik 26 übertragen.In the present case, the lifting device 21 is U-shaped in plan (FIG. 2) with a transverse motor housing 22 and lifting housings 23 and 24 adjoining it in the manner of legs. In the motor housing 22, an (electric) drive motor 25 is accommodated approximately in the center. From this, the lifting drive is transmitted to the two lifting housings 23 and 24 or to a lifting mechanism 26 arranged within the same.

Wie insbesondere aus Fig. 6 ersichtlich, wird der heb- und senkbare Teil der Hubgehäuse 23, 24 durch eine nach unten offene, im Querschnitt etwa U-förmige Gehäuseabdeckung 27 gebildet. Diese erstreckt sich im vorliegenden Falle über die volle Länge der Hubgehäuse 23, 24. An der Innenseite, nämlich an einer Seitenwand 28, ist am unteren Ende eine Teilplattform 29 bzw. eine sich in Längsrichtung der Gehäuseabdeckung 27 erstreckende Aufnahmeschiene angebracht. Diese dient zur Auflagerung von (zwei) Stuhlbeinen 30. Die beiden anderen Stuhlbeine 31 finden Aufnahme auf der gegenüberliegenden Seite auf einer entsprechenden Teilplattform 32 des Hubgehäuses 24. Die Teilplattformen 29, 32 werden gleichzeitig und synchron auf- und abbewegt, so daß der Sessel 20 eine entsprechende Hubbewegung vollzieht.As can be seen in particular from FIG. 6, the part of the lifting housing 23, 24 which can be raised and lowered is formed by a housing cover 27 which is open at the bottom and is approximately U-shaped in cross section. In the present case, this extends over the full length of the lifting housing 23, 24. On the inside, namely on a side wall 28, a partial platform 29 or a receiving rail extending in the longitudinal direction of the housing cover 27 is attached to the lower end. This serves to support (two) chair legs 30. The other two chair legs 31 are received on the opposite side on a corresponding sub-platform 32 of the lifting housing 24. The sub-platforms 29, 32 are moved up and down simultaneously and synchronously, so that the armchair 20 performs a corresponding lifting movement.

Die Hubmechanik 26 ist bei dem vorliegenden Ausführungsbeispiel nach Art eines Parallelogrammgestänges aufgebaut. Innerhalb der Hubgehäuse 23, 24 sind im Abstand voneinander jeweils zwei Hubstützen 33, 34 schwenkbar gelagert. Entsprechende Schwenklager 35 der etwa dreieckförmigen Hubstützen 33, 34 befinden sich im unteren Bereich des Hubgehäuses 23, 24. Über dieses Schwenklager 35 sind die Hubstützen 33, 34 mit einem als Hohlkastenprofil ausgebildeten Tragschenkel 36 eines (U-förmigen) Tragrahmens verbunden. Der Tragschenkel 36 erstreckt sich innerhalb und in Längsrichtung des Hubgehäuses 23, 24. Die Hubstützen 33, 34 sind durch eine Kopplungsstange 37 miteinander verbunden. Diese ist mit Abstand vom Schwenklager 35 an die Hubstützen 33, 34 angelenkt, nämlich etwa in einer in Ausgangsstellung oberen Ecke der dreieckförmigen Hubstützen 33, 34.In the present exemplary embodiment, the lifting mechanism 26 is constructed in the manner of a parallelogram linkage. Two lifting supports 33, 34 are each pivotably mounted within the lifting housings 23, 24 at a distance from one another. Corresponding pivot bearings 35 of the approximately triangular lifting supports 33, 34 are located in the lower region of the lifting housing 23, 24. Via this pivot bearing 35, the lifting supports 33, 34 are connected to a support leg 36 of a (U-shaped) support frame designed as a hollow box profile. The support leg 36 extends inside and in the longitudinal direction of the lifting housing 23, 24. The lifting supports 33, 34 are connected to one another by a coupling rod 37. This is articulated at a distance from the pivot bearing 35 to the lifting supports 33, 34, namely approximately in an upper corner of the triangular lifting supports 33, 34 in the starting position.

Mit Abstand sowohl von den Schwenklagern 35 wie auch von den Anlenkstellen der Kopplungsstange 37, nämlich in Bereich einer dritten Ecke der Hubstützen 33, 34, ist an diesen jeweils eine Tragrolle 38 angeordnet. Diese tritt in eine im wesentlichen horizontale Tragschiene 39 ein, die mit der Teilplattform 29, 32 bzw. mit der Gehäuseabdeckung 27 auf der Innenseite der Seitenwand 28 verbunden ist.At a distance from both the pivot bearings 35 and from the articulation points of the coupling rod 37, namely in the region of a third corner of the lifting supports 33, 34, a support roller 38 is arranged on each of these. This enters an essentially horizontal mounting rail 39, which is connected to the partial platform 29, 32 or to the housing cover 27 on the inside of the side wall 28.

Die so ausgebildete Hubmechanik 26 arbeitet in der Weise, daß die dem Antriebsmotor 25 zugekehrte Hubstütze 34 durch Verschwenken um das Schwenklager 35 im Uhrzeigersinn (aus der Ausgangsstellung gemäß Fig. 5) aufgerichtet wird. Durch die Verbindung über die Kopplungsstange 37 wird die Hubstütze 33 in gleicher Weise aufgerichtet. Dabei nimmt die an dem zum Schwenklager 35 gegenüberliegenden Ende der Hubstütze 33, 34 angeordnete Tragrolle 38 die Tragschiene 39 in hebendem Sinne mit. Während der Kreisbogenbewegung der Tragrollen 38 laufen diese in der Tragschiene 39. Letztere wird demnach an zwei Stützpunkten angehoben unter Mitnahme der Gehäuseabdeckung 27 und der an diesen angeordneten Teilplattformen 29, 32. Die Absenkbewegung erfolgt in entsprechender Weise bei umgekehrter Schwenkbewegung der Hubstützten 33, 34.The lifting mechanism 26 designed in this way works in such a way that the lifting support 34 facing the drive motor 25 is erected by pivoting about the pivot bearing 35 in a clockwise direction (from the starting position according to FIG. 5). By connecting through the Coupling rod 37, the lifting support 33 is erected in the same way. The support roller 38 arranged on the end of the lift support 33, 34 opposite the pivot bearing 35 takes the support rail 39 in a lifting sense. During the circular arc movement of the support rollers 38, these run in the support rail 39. The latter is therefore raised at two support points, taking the housing cover 27 and the sub-platforms 29, 32 arranged thereon.

Der Antriebsmotor 25 ermöglicht eine stufenlose Auf- und Abbewegung der Teilplattformen 29, 32. Die jeweilige Höhenstellung ist an einer Skala 40 ablesbar, die an einer Seitenwand 41 des Motorgehäuses 22 angebracht ist. Die obere Begrenzung (Oberkante) der Gehäuseabdeckung 27 bildet zugleich den "Zeiger" zur Feststellung der Höhenlage an der Skala 40.The drive motor 25 enables a continuous up and down movement of the partial platforms 29, 32. The respective height position can be read on a scale 40 which is attached to a side wall 41 of the motor housing 22. The upper limit (upper edge) of the housing cover 27 also forms the "pointer" for determining the height on the scale 40.

Wie aus Fig. 7 ersichtlich, ist der Antriebsmotor 25 über eine nach beiden Seiten gerichtete Antriebswelle 42 mit der zugekehrten Hubstütze 34 verbunden, und zwar im Bereich des Schwenklagers 35. Die Antriebswelle 42 ist über einen Befestigungsbolzen 43 am Tragschenkel 36 des Tragrahmens gelagert. Die Betätigung des Antriebsmotors 25 erfolgt durch Fernbedienung, insbesondere über ein elektrisches Kabel (nicht dargestellt) mit Schaltknopf.As can be seen from FIG. 7, the drive motor 25 is connected to the facing lifting support 34 via a drive shaft 42 directed towards both sides, specifically in the area of the pivot bearing 35. The drive shaft 42 is mounted on the support leg 36 of the support frame via a fastening bolt 43. The drive motor 25 is actuated by remote control, in particular via an electrical cable (not shown) with a switch button.

Zur Bestimmung der optimalen Sitztiefe des Sitzmöbels ist bei dem vorliegenden Sessel 20 dessen Sitzpolster 44 verschiebbar in der Sitzebene. Zu diesem Zweck ist das Sitzpolster bzw. eine untere Tragplatte 45 desselben gleitend auf einem Sesselrahmen 46, nämlich auf Seitenholmen 47 desselben, gelagert. Gemäß Vorschlag der Fig. 10 und 11 ist zu diesem Zweck auf der Oberseite der Seitenholme 47 eine streifenförmige Gleitauflage 48, beispielsweise ein Metall- oder Kunststoffprofil, angeordnet. Die jeweilige Relativstellung des Sitzpolsters 44 in bezug auf den Sesselrahmen 46 und damit die Sitztiefe wird durch einen am Sitzpolster 44 angebrachten Zeiger 49 auf einer Skala 50 angezeigt, die an der Außenseite des einen Seitenholms 47 angebracht ist.To determine the optimum seat depth of the seating furniture, the seat cushion 44 of the present armchair 20 is displaceable in the seat plane. For this purpose, the seat cushion or a lower support plate 45 of the same is slidably mounted on an armchair frame 46, namely on side rails 47 of the same. As suggested 10 and 11, a strip-shaped sliding support 48, for example a metal or plastic profile, is arranged for this purpose on the upper side of the side rails 47. The respective relative position of the seat cushion 44 with respect to the armchair frame 46 and thus the seat depth is indicated by a pointer 49 attached to the seat cushion 44 on a scale 50 which is attached to the outside of the one side rail 47.

Das verschiebbare Sitzpolster 44 ist gegen Abheben auf dem Sesselrahmen 46 gesichert. Im vorliegenden Fall (Fig. 10) ist an den Seitenholmen 47 ein Winkelprofil 51 angebracht. Dessen horizontal gerichteter oberer Schenkel 52 ragt in eine ebenfalls winkelförmige Halteschiene 53 an der Unterseite des Sitzpolsters 44 bzw. der Tragplatte 45. Die vorstehende formschlüssige Verbindung weist ausreichend Spiel auf, um die Verschiebungen des Sitzpolsters 44 zu ermöglichen. Winkelprofil 51 und Halteschiene 53 erstrecken sich, wie aus Fig. 9 ersichtlich, über einen Teil der Längserstreckung des Sitzpolsters 44.The displaceable seat cushion 44 is secured against lifting off on the armchair frame 46. In the present case (FIG. 10), an angle profile 51 is attached to the side rails 47. Its horizontally directed upper leg 52 protrudes into a likewise angled holding rail 53 on the underside of the seat cushion 44 or the support plate 45. The above positive connection has sufficient play to enable the displacements of the seat cushion 44. As can be seen in FIG. 9, the angle profile 51 and the holding rail 53 extend over part of the longitudinal extent of the seat cushion 44.

In Verlängerung der vorstehenden Schiebeverbindung ist eine Rasteinrichtung angeordnet zur leicht lösbaren Arretierung des Sitzpolsters 44 in unterschiedlichen Relativpositionen. Die Rasteinrichtung besteht aus einer elastisch bewegbaren Sperre 54, die an dem Seitenholm 47 des Sesselrahmens 46 angebracht ist und eine nach oben gerichtete, durch Feder 55 belastete Schnepperkugel 56 aufweist. Diese tritt in Vertiefungen 57 einer Rastschiene 58 an der Unterseite des Sitzpolsters 44 entsprechend der eingestellten Relativstellung ein.In an extension of the above sliding connection, a locking device is arranged for easily releasable locking of the seat cushion 44 in different relative positions. The locking device consists of an elastically movable lock 54, which is attached to the side rail 47 of the armchair frame 46 and has an upwardly directed, loaded by spring 55 spring ball 56. This occurs in recesses 57 of a locking rail 58 on the underside of the seat cushion 44 in accordance with the set relative position.

Eine weitere Meß- bzw. Verstellmöglichkeit des Sessels ist in Fig. 12 und 13 gezeigt. Hier geht es um eine Kippbarkeit des Sitzpolsters 44 zur Einstellung des Sitzwinkels. Zu diesem Zweck ist das Sitzpolster 44 auf der einer Rückenlehne 59 des Sessels 20 zugekehrten Seite mit einem Schwenklager 60 am Sesselgestell bzw. am Sesselrahmen 46 angebracht. Auf der von dem Schwenklager 60 abliegenden Seite ist eine Schwenkmechanik 61 an der Unterseite des Sitzpolsters 44 angebracht. Die Schwenkmechanik 61 besteht aus einem sich quer zwischen den Seitenholmen 47 erstreckenden Schwenkbügel 62 mit Handgriff 63. An den Enden desselben angeordnete Laschen 64 des Schwenkbügels 62 sind über ein Kipplager 65 mit den benachbarten Seitenholmen 47 verbunden. Das Kipplager 65 befindet sich mit Abstand sowohl vom Handgriff 63 wie auch von freien Enden der Laschen 64, an denen jeweils ein Führungszapfen 66 angeordnet ist. Die Laschen 64 wirken aufgrund dieser Anordnung als zweiarmige Hebel. Die Führungszapfen 66 treten in eine Kulisse 67 eines jeweils seitlich an der Unterseite des Sitzpolsters 44 angebrachten Beschlagteils 68 ein. Die Kulisse 67 ist so geformt, daß der Führungszapfen 66 mehrere stabile Positionen innerhalb der Kulisse 67 durch Ausbuchtungen oder dergleichen einnehmen kann.Another possibility to measure or adjust the armchair is shown in Figs. 12 and 13. This is about a tiltability of the seat cushion 44 to adjust the seat angle. For this purpose, the seat cushion 44 is attached to the side facing a backrest 59 of the armchair 20 with a pivot bearing 60 on the armchair frame or armchair frame 46. On the side remote from the pivot bearing 60, a pivot mechanism 61 is attached to the underside of the seat cushion 44. The swivel mechanism 61 consists of a swivel bracket 62 with a handle 63 which extends transversely between the side rails 47. Lugs 64 of the swivel bracket 62 arranged at the ends of the swivel bracket 62 are connected to the adjacent side rails 47 via a tilting bearing 65. The tilting bearing 65 is located at a distance from both the handle 63 and the free ends of the tabs 64, on each of which a guide pin 66 is arranged. Due to this arrangement, the tabs 64 act as two-armed levers. The guide pins 66 enter a link 67 of a fitting part 68 which is attached laterally to the underside of the seat cushion 44. The link 67 is shaped so that the guide pin 66 can assume several stable positions within the link 67 through bulges or the like.

Durch Verschwenken des Schwenkbügels 62 um das Kipplager 65 werden die Laschen 64 aufgerichtet (bei Bewegung aus der Ausgangsstellung gemäß Fig. 13). Dadurch wird der Führungszapfen 66 unter Anheben des Sitzpolsters 44 in der Kulisse 67 bis zur nächsten Rastposition bewegt. Das Sitzpolster kann im vorliegenden Falle bis zu der in Fig. 13 strichpunktiert gezeigten Stellung angehoben werden, wobei der Führungszapfen 66 das andere Ende 67 der Kulisse erreicht hat.By pivoting the swivel bracket 62 about the tilt bearing 65, the tabs 64 are erected (when moving from the starting position according to FIG. 13). As a result, the guide pin 66 is moved to the next latching position while lifting the seat cushion 44 in the link 67. In the present case, the seat cushion can be raised up to the position shown in broken lines in FIG. 13, the guide pin 66 having reached the other end 67 of the link.

In ähnlicher Weise ist bei dem vorliegenden Sessel 20 die Rückenlehne 59 verstellbar, nämlich kippbar. Das untere Ende der Rückenlehne 59 ist zu diesem Zweck mit einem Kipplager 69 am Sesselgestell, nämlich an Sesselrahmen 46 - an der Innenseite der Seitenholme 47 - gelagert. Die stufenweise Festsetzung der Rückenlehne 59 in den möglichen Winkelstellungen erfolgt durch eine Stellmechanik 70, die mit den entsprechend nach oben verlängerten rückseitigen Stuhlbeinen 30 und 31 zusammenwirkt.Similarly, in the present armchair 20, the backrest 59 is adjustable, namely tiltable. For this purpose, the lower end of the backrest 59 is supported by a tilt bearing 69 on the armchair frame, namely on the armchair frame 46 - on the inside of the side rails 47. The step-by-step fixing of the backrest 59 in the possible angular positions takes place by means of an adjusting mechanism 70 which interacts with the correspondingly upward-extending rear chair legs 30 and 31.

Auch bei der vorliegenden Stellmechanik 20 ist ein Schwenkbügel 71 mit Handgriff 72 und seitlichen Laschen 73 vorgesehen. Die Laschen 73 am Ende des Handgriffs 72 sind mit einer im vorliegenden Falle sägezahnförmigen Kulisse 74 versehen. An dem zum Handgriff 72 gegenüberliegenden Ende sind die Laschen 73 über ein Kipplager 75 mit dem Sesselgestell, nämlich mit dem oberen Bereich der entsprechend verlängerten Stuhlbeine 30, 31 verbunden. An der Rückseite der Rückenlehne 59 ist in diesem Bereich ein nach rückwärts abstehender Steg 76 angebracht, beispielsweise ein Winkelprofil mit zur Rückseite weisendem Schenkel. An diesem Steg 76 ist auf der der Lasche 73 zugekehrten Seite ein Führungszapfen 77 angebracht, der verschiebbar in die Kulisse 74 eintritt.A swivel bracket 71 with a handle 72 and side tabs 73 is also provided in the present actuating mechanism 20. The tabs 73 at the end of the handle 72 are provided with a sawtooth-shaped link 74 in the present case. At the end opposite the handle 72, the tabs 73 are connected via a tilting bearing 75 to the chair frame, namely to the upper region of the correspondingly elongated chair legs 30, 31. On the back of the backrest 59 in this area there is a web 76 which projects backwards, for example an angular profile with a leg pointing towards the back. On this web 76, a guide pin 77 is attached on the side facing the tab 73 and slidably enters the link 74.

In Fig. 15 ist die aufgerichtete Stellung der Rückenlehne 59 gezeigt. Der Führungszapfen 77 befindet sich am oberen Ende der Kulisse 74. Die "Eckpunkte" der Kulisse 74 bilden eine mögliche Alternativstellung der Rückenlehne 59. Die Endstellung mit der äußersten Neigung ist durch das untere, äußere Ende der Kulisse 74 gegeben. Der Schwenkbügel 71 wird dabei von Hand so bewegt und verschwenkt, daß der Führungszapfen 77 in die gewünschte Position innerhalb der Kulisse 74 gelangt.15 shows the upright position of the backrest 59. The guide pin 77 is located at the upper end of the link 74. The "corner points" of the link 74 form a possible alternative position of the backrest 59. The end position with the extreme inclination is given by the lower, outer end of the link 74. The swivel bracket 71 is moved and pivoted by hand so that the guide pin 77 reaches the desired position within the link 74.

Die Laschen 73 sind aufgrund der Lagerung und Ausbildung im vorliegenden Falle als einarmige Hebel ausgebildet.The tabs 73 are formed due to the storage and training in the present case as a one-armed lever.

Der Sessel 20 ist weiterhin mit einer anpaßbaren Lendenstütze 78 in Lendenhöhe der Rückenlehne 59 ausgebildet. Diese ist zu diesem Zweck mit einer Polsterauflage 79, beispielsweise aus Schaumstoff, auf einer Rückplatte 80 der Rückenlehne 59 ausgebildet. Die Rückplatte 80 besteht zweckmäßigerweise aus Schichtholz. Auf der der Polsterauflage 79 zugekehrten Seite der Rückplatte 80 ist ein sich quer über die Rückenlehne 59 erstreckendes Luftpolster 81 augebracht, also ein aufblasbarer Hohlkörper aus elastischem Werkstoff (Gummi, Kunststoff). Durch Einführen von Luft in dieses Luftpolster 81 erfolgt eine Volumenvergrößerung in Richtung zur Polsterauflage 79, wodurch diese entsprechend vorgewölbt wird (strichpunktierte Linie in Fig. 16). Zum Aufblasen des Luftpolsters 81 dient eine von Hand zu bedienende Luftpumpe 82, die über einen Luftschlauch 83 mit dem Luftpolster 81 verbunden ist. Der Luftschlauch 83 wird an der Unterseite der Rückenlehne 59 in diese eingeführt und verläuft innerhalb der Polsterauflage 79 bzw. zwischen dieser und der Rückplatte 80. Im Bereich der Luftpumpe 82 befindet sich ein von Hand zu bedienendes Entlüftungsventil 84, welches zugleich als Überdruckventil wirkt.The armchair 20 is also formed with an adjustable lumbar support 78 at the lumbar height of the backrest 59. For this purpose, this is formed with a cushion pad 79, for example made of foam, on a back plate 80 of the backrest 59. The back plate 80 suitably consists of plywood. On the side of the back plate 80 facing the cushion pad 79 there is an air cushion 81 extending transversely over the backrest 59, that is to say an inflatable hollow body made of elastic material (rubber, plastic). By introducing air into this air cushion 81 there is an increase in volume in the direction of the cushion support 79, whereby this is accordingly bulged out (dash-dotted line in FIG. 16). An air pump 82, which is operated by hand and is connected to the air cushion 81 via an air hose 83, serves to inflate the air cushion 81. The air hose 83 is inserted into the underside of the backrest 59 and runs inside the cushion pad 79 or between it and the back plate 80. In the area of the air pump 82 there is a manually operated vent valve 84 which also acts as a pressure relief valve.

Zur Sicherung des Luftpolsters 81 gegenüber Dehnung ist dieses innerhalb einer Umhüllung 85 aus zugfestem Werkstoff (Textil) angeordnet. Die Umhüllung 58 wirkt als Dehnungsbegrenzung und ist mit ihren Rändern fest an der Rückplatte 80 angebracht. Die vorgenannte Umhüllung 58 schließt das Luftpolster 81 mit den vorgegebenen Maximalabmessungen des Luftpolsters 81 vollständig ein - bis auf die der Rückplatte 80 zugekehrte Seite.To secure the air cushion 81 against expansion, it is arranged within a casing 85 made of tensile material (textile). The envelope 58 acts as a limitation of expansion and is firmly attached to the back plate 80 with its edges. The aforementioned sheath 58 completely encloses the air cushion 81 with the predetermined maximum dimensions of the air cushion 81 - except for the side facing the rear plate 80.

Die beschriebenen Einrichtungen zur Verstellung von Teilen des Sessels können nicht nur in Verbindung mit einem "Meßsessel" zum Einsatz kommen, sondern auch in Verbindung mit handelsfähigen Sesseln bzw. Stühlen.The described devices for adjusting parts of the armchair can be used not only in connection with a "measuring armchair", but also in connection with commercially available armchairs or chairs.
