The damping unit can also be controlled by a motor drive element, e.g. an electric motor drive, be interchangeable. When using a gas spring in addition to the electric motor drive, a gas spring can also allow a reduced design. A releasable gas spring can also be used as a motor drive element.

In einer bevorzugten Ausführung ist das zumindest eine Dämpfungselement eine Gasfeder und das zumindest eine Kraftspeicherelement eine Dämpfungsfeder. Dadurch ergibt sich der besondere Vorteil, dass in der eingefahrenen Position der Stütze diese vollständig unter dem Sitzrahmen eingezogen ist und nicht herunterhängt.In a preferred embodiment, the at least one damping element is a gas spring and the at least one energy storage element is a damping spring. This results in the particular advantage that in the retracted position of the support this is completely retracted under the seat frame and does not hang down.

Das Schwenkgetriebe kann mit dem Untergestell über zumindest einen Lenkhebel gekoppelt sein, wodurch sich eine Bewegungskurve der Stütze vorteilhaft einstellen lässt.The swivel gear can be coupled to the undercarriage via at least one steering lever, whereby a movement curve of the support can be adjusted advantageously.

Die Stütze kann ein Stützengetriebe aufweisen, welches zur Verstellung einer Stützenplatte derart mit dem Sitzrahmen gekoppelt ist, dass die Position der Stütze relativ zu dem Stützenrahmen einen wesentlich größeren Abstand von der Schwenkachse einnimmt als in der eingefahrenen Position, und in der eingefahrenen Position der Stütze relativ zu dem Stützenrahmen einen wesentlich kleineren Abstand von der Schwenkachse als in der ausgefahrenen Position einnimmt.The support may include a support gear coupled to the seat frame for adjustment of a support plate such that the position of the support relative to the support frame occupies a substantially greater distance from the pivot axis than in the retracted position and relative to the retracted position of the support to that Column frame occupies a much smaller distance from the pivot axis than in the extended position.

Dazu kann das Stützengetriebe einen ersten Hebel und einen zweiten Hebel aufweisen, welche um eine Verbindungsachse verschwenkbar gekoppelt sind, wobei der erste Hebel mit einem Ende mit einem linear verstellbaren Antriebsschieber um eine Kreuzachse, die in Langlöchern des Antriebsschiebers und des ersten Hebels geführt ist, verschwenkbar verbunden ist und mit der Stützenplatte über den zweiten Hebel in einer Stützachse gekoppelt ist, wobei der linear verstellbare Antriebsschieber mit dem Sitzrahmen über einen Antriebshebel gekoppelt ist. Hierdurch wird eine besonders flache Bauweise der Stütze gewährleistet.For this purpose, the support gear having a first lever and a second lever, which are pivotally coupled about a connecting axis, wherein the first lever with one end with a linearly adjustable drive slide about a cross axis, which is guided in slots of the drive slide and the first lever pivotable is connected and coupled to the support plate via the second lever in a support axis, wherein the linearly adjustable drive slide is coupled to the seat frame via a drive lever. As a result, a particularly flat design of the support is guaranteed.

Hierbei ist vorgesehen, dass das Stützengetriebe eine Stützenhaltefeder aufweist und mit ihr gekoppelt ist. In einer bevorzugten Ausführung ist die Stützenhaltefeder zwischen dem Antriebsschieber und dem Stützenrahmen angeordnet und in der eingefahrenen Position der Stütze gespannt. Damit ergibt sich der besondere Vorteil, dass die Stützenplatte in der eingefahren Position gehalten ist.It is provided that the support gear has a support holding spring and is coupled thereto. In a preferred embodiment, the support holding spring is arranged between the drive slide and the support frame and stretched in the retracted position of the support. This results in the particular advantage that the support plate is held in the retracted position.

Es ist besonders bevorzugt, dass der Sitzrahmen als Laserknickteil ausgebildet ist. Hierbei kann er aus einem Rechteckrohr gebildet sein. Dadurch ergibt sich der Vorteil, dass in der Fertigung enge Toleranzen der an dem Sitzrahmen angelegten Standhebel für die Bewegung des Sitzrahmens gegenüber dem Untergestell eingehalten werden können, wodurch sich eine Nacharbeit fast vollständig reduziert und einen Leichtgängigkeit der Bewegung des Sitzrahmens leicht herstellen lässt.It is particularly preferred that the seat frame is formed as a laser crease part. In this case, it can be formed from a rectangular tube. This results in the advantage that in the production close tolerances of the applied to the seat frame stand lever for the movement of the seat frame relative to the base can be met, which almost completely reduces rework and ease of movement of the seat frame can be produced.

Die Stützenplatte kann mit dem Stützenrahmen mit Auszugelementen verbunden sein, die als Teilauszugelemente ausgebildet sind. Dadurch ist eine besonders schmale und stabile Bauweise ermöglicht.The support plate may be connected to the support frame with pull-out elements, which are designed as Teilauszugelemente. This allows a particularly narrow and stable construction.

Fig. 1a zeigt eine perspektivische Ansicht einer erfindungsgemäßen Vorrichtung 1 in einem Sitzmöbel 60. Fig. 1b zeigt eine Seitenansicht dazu. Das Sitzmöbel 60 ist ohne Polsterung und ohne Bezug dargestellt. Fig. 1a shows a perspective view of a device 1 according to the invention in a chair 60. Fig. 1b shows a side view. The chair 60 is shown without upholstery and without cover.

In diesem Beispiel dient ein Plattenelement 62 als Standfuß auf dem Boden. Auf diesem Plattenelement 62 ist das Sitz-/Liegemöbelchassis 1 mit einem Untergestell 2 angebracht. Ein Rückenteil 61 des Sitzmöbels 60 ist an einem hinteren Ende des Sitz-/Liegemöbelchassis 1 fest oder verschwenkbar befestigt. Am vorderen Ende weist das Sitz-/Liegemöbelchassis 1 eine Stütze 12 auf, die z.B. auch als Fußstütze bezeichnet wird und in der Figur in eine ausgefahrene Position verschwenkt ist.In this example, a plate member 62 serves as a pedestal on the floor. On this plate member 62, the seat / recumbent chassis 1 is mounted with a base 2. A back portion 61 of the chair 60 is fixedly or pivotally attached to a rear end of the seat / recumbent chassis 1. At the front end, the seat / recumbent chassis 1 has a support 12, e.g. Also referred to as a footrest and is pivoted in the figure in an extended position.

Das Sitz-/Liegemöbelchassis 1 bildet eine Art Chassis, welches mit dem Untergestell 2 eine Anpassung an verschiedene Standfüße bildet, und gleichzeitig einen Sitz, das Rückenteil und die Stütze 12 aufnehmen kann.The seat / recumbent chassis 1 forms a kind of chassis, which forms with the base 2 an adaptation to different feet, while a seat, the back and the support 12 can accommodate.

Mit dem Begriff "vorn" ist die Vorderseite des Sitzmöbels 60 und des Sitz-/Liegemöbelchassis 1 zu verstehen, wobei unter dem Begriff "hinten" die Rückseite des Sitzmöbels 60 mit dem Rückenteil 61 zu verstehen ist. Der Begriff "Längsrichtung des Sitz-/Liegemöbelchassis 1" bezieht sich auf die Richtung, welche vom Rückenteil 61 zur Stütze 12 verläuft.The term "front" is the front of the chair 60 and the seat / reclining chassis 1 to understand, where the term "behind" the back of the chair 60 with the back part 61 is to be understood. The term "longitudinal direction of the seat / recumbent chassis 1" refers to the direction which extends from the back 61 to the support 12.

In Fig. 2 ist eine perspektivische Ansicht des erfindungsgemäßen Sitz-/Liegemöbelchassis 1 von unten in ausgefahrener Position der Stütze 12 dargestellt.In Fig. 2 is a perspective view of the seat / reclining furniture chassis 1 of the invention shown from below in the extended position of the support 12.

Das Untergestell 2 besteht hier aus einem bogenförmigen Rohrkörper, welcher an seinem herausragenden Abschnitt eine Aufnahme, z.B. einen Rohrabschnitt, für unterschiedliche Standfüße besitzt. An jedem seiner beiden Enden trägt das Untergestell 2 jeweils einen Gestellwinkel 35. Jeder Gestellwinkel 35 weist einen außenliegenden, sich nach vorn erstreckenden Seitenarm 3 auf. Innenliegend ist jeder Gestellwinkel 35 mit einem Längslenkerhalter 36 versehen, welche mit einem Schwenkgetriebe 11 zusammenwirken, das weiter unten noch ausführlich erläutert wird.The base 2 here consists of an arcuate tubular body, which at its protruding portion a receptacle, e.g. a pipe section, has different feet. At each of its two ends, the base frame 2 carries in each case a frame angle 35. Each frame angle 35 has an external, forwardly extending side arm 3. Internally, each frame angle 35 is provided with a trailing arm holder 36, which cooperate with a pivoting gear 11, which will be explained in more detail below.

An jedem Seitenarm 3 ist an seinem vorderem Ende ein Standhebel 4 und an seinem hinteren Ende ein Standhebel 5 gelenkig in Standlenkerachsen 40 angelenkt. Die anderen Enden dieser vier Standhebel 4 und 5 sind an einem Sitzrahmen 6 jeweils in Sitzstandlenkerachsen 41 verschwenkbar angebracht. Der Sitzrahmen 6 dient zur Aufnahme eines Sitzes des Sitzmöbels 60 und ist rechteckförmig ausgebildet. In dieser gezeigten Ausführung ist der Sitzrahmen 6 aus einem Rechteckrohr gebildet, wobei er ein so genanntes Laserknickteil ist. Dabei bildet ein Querteil 8 (hinten an des Sitz-/Liegemöbelchassis 1) ein Basisteil, an dessen Enden jeweils ein Seitenteil 7 nach vorn geknickt ist. Die Seitenteile 7 sind vorn mittels eines Frontteils 9 verbunden. An den Seitenteilen 7 sind die Standhebel 4, 5 jeweils in einem bestimmten Abstand in den Sitzstandlenkerachsen 41 angebracht, deren Abstand von großer Bedeutung ist. Das Laserknickteil hat den besonderen Vorteil, dass die an ihm, insbesondere die Positionen der Sitzstandlenkerachsen 41, bei Serienfertigung in entsprechenden Bearbeitungsvorrichtungen herzustellenden Bohrungen, Anbringungen usw. mit engen Toleranzen herstellbar sind. Dadurch wird eine Nacharbeit erheblich reduziert. Außerdem wird eine Leichtgängigkeit des Sitz-/Liegemöbelchassis 1 beim Verstellen verbessert. Der Sitzrahmen 6 ist über die an ihm und an den Seitenarmen 3 verschwenkbaren Standhebel 4, 5 in einem bestimmten Sitzteilschwenkwinkel 59 (siehe Fig. 7a-7b) nach vorn in eine erste Stellung und nach hinten in eine zweite Stellung bewegbar. In der hier in Fig. 2 gezeigten ausgefahrenen Position der Stütze 12 ist der Sitzrahmen 6 in der zweiten Stellung.At each side arm 3 is at its front end a stand lever 4 and articulated at its rear end a stand lever 5 hinged in the armrest axles 40. The other ends of these four stand levers 4 and 5 are pivotally mounted on a seat frame 6 in each Sitzstandlenkerachsen 41. The seat frame 6 serves to receive a seat of the seat 60 and is rectangular in shape. In this illustrated embodiment, the seat frame 6 is formed of a rectangular tube, wherein it is a so-called laser crease part. In this case, a cross member 8 (rear of the seat / reclining furniture chassis 1) forms a base part, at the ends of each side part 7 is folded forward. The side parts 7 are connected at the front by means of a front part 9. At the side parts 7, the stand lever 4, 5 are each mounted at a certain distance in the seat post-link axles 41, whose distance is of great importance. The laser kink part has the particular advantage that the him, in particular the positions of the seat post links 41 at Series production in corresponding processing devices to produce bores, attachments, etc. can be produced with tight tolerances. This considerably reduces reworking. In addition, a smoothness of the seat / reclining furniture chassis 1 is improved when adjusting. The seat frame 6 is about the pivotable on it and on the side arms 3 stand lever 4, 5 in a certain seat pivot part 59 (see Fig. 7a-7b ) can be moved forward into a first position and backwards into a second position. In the here in Fig. 2 shown extended position of the support 12, the seat frame 6 in the second position.

Dieser auf diese Weise gegenüber dem Untergestell 2 des Sitz-/Liegemöbelchassis 1 bewegliche Sitzrahmen 6 ist mit der Stütze 12 über das Schwenkgetriebe 11 derart gekoppelt, dass die Stütze 12 in der ersten Stellung des Sitzrahmens 6 eingefahren ist (d.h. die eingefahrene Position einnimmt) und in der zweiten Stellung des Sitzrahmens 6 ausgefahren ist (d.h. die ausgefahrene Position einnimmt). Die eingefahrene Position wird unten noch erläutert und gezeigt. Der Sitzrahmen 6 kann durch eine gewollte Bewegung einer in dem Sitzmöbel 60 befindlichen Person willentlich nach hinten in die zweite Stellung bewegt werden, um so die Stütze 12 auszufahren. Zum Einfahren der Stütze 12 wird der Sitzrahmen 6 von der Person nach vorn in die erste Stellung bewegt. Eine Unterstützung dieser Verstellbewegungen ermöglicht eine Dämpfungseinheit 10, welche zwischen dem Querteil 8 des Sitzrahmens 6 und dem Schwenkgetriebe 11 angeordnet ist. Die Dämpfungseinheit 10 ermöglicht jeweils eine gedämpfte Endbewegung in die ausgefahrene bzw. eingefahrene Position der Stütze 12 hinein. Hierzu ist die Dämpfungseinheit 10 mit einer Gasfeder als Dämpfungselement 31 und zusätzlich mit einer Dämpfungsfeder 30 versehen, welche hier parallel zum Dämpfungselement 31 angeordnet ist. Diese Anordnung ist Fig. 3a zu entnehmen. In Fig. 2 ist sie ausgehängt gezeigt. Die zusätzliche Dämpfungsfeder 30 der Dämpfungseinheit 10 gestattet es außerdem, dass die eingefahrene Position der Stütze 12 sicher gehalten ist und bleibt. Das bedeutet, dass eine unter das Sitz-/Liegemöbelchassis 1 eingeklappte Stütze 12 (siehe u.a. Fig. 4a-4b) vollständig eingeklappt bleibt und nicht herunterhängt. Dies wird unten noch im Zusammenhang mit Fig. 7a-7b näher erläutert.This in this way relative to the base 2 of the seat / recumbent chassis 1 movable seat frame 6 is coupled to the support 12 via the pivot gear 11 such that the support 12 is retracted in the first position of the seat frame 6 (ie, the retracted position occupies) and extended in the second position of the seat frame 6 (ie, the extended position occupies). The retracted position will be explained and shown below. The seat frame 6 can be deliberately moved rearward to the second position by a deliberate movement of a person in the chair 60, so as to extend the stay 12. For retracting the support 12, the seat frame 6 is moved forward by the person in the first position. A support of these adjustment movements allows a damping unit 10, which is arranged between the transverse part 8 of the seat frame 6 and the pivot gear 11. The damping unit 10 in each case enables a damped end movement into the extended or retracted position of the support 12. For this purpose, the damping unit 10 is provided with a gas spring as a damping element 31 and additionally with a damping spring 30, which is arranged here parallel to the damping element 31. This arrangement is Fig. 3a refer to. In Fig. 2 she is shown posted. The additional damping spring 30 of the damping unit 10 also allows the retracted position of the Support 12 is securely held and stays. This means that a folded under the seat / reclining chassis 1 support 12 (see, inter alia Fig. 4a-4b ) remains completely folded and does not hang down. This is still related below Fig. 7a-7b explained in more detail.

Die Dämpfungseinheit 10 ist über einen Dämpfungshalter 14 mit dem Sitzrahmen 6 an dessen Querteil 8 in einer Dämpfungshalterachse 42 verschwenkbar angebracht. Mit dem Schwenkgetriebe 11 ist die Dämpfungseinheit 10 über eine Querstrebe 33, die auch einen Federhalter 32 für die zusätzliche Dämpfungsfeder 30 aufweist, gekoppelt. Das Schwenkgetriebe 11 dient dazu, die Bewegung des Sitzrahmens 6 auf die Stütze 12 in geeigneter Weise so zu übertragen, dass eine leichtgängige Verstellung der Stütze 12 möglich ist. Das Schwenkgetriebe 11 ist als Hebelgetriebe ausgebildet und mit dem Sitzrahmen 6, dem Untergestell 2 und der Stütze 12 über Hebel verbunden. Es weist hier auf jeder Seite in Längsrichtung des Sitz-/Liegemöbelchassis 1 einen leicht nach unten gekrümmten Längslenker 18 auf. Die Längslenker 18 sind jeweils mit ihren hinteren Enden mit dem jeweiligen Längslenkerhalter 36 in einer Längslenkerachse 44 verschwenkbar verbunden. Die Längslenker 18 sind im vorderen Drittel mit der Querstrebe 33 und einer parallel dazu liegenden Rundstrebe 34 untereinander verbunden. Die Querstrebe 33 ist in den Längslenkern 18 in einer Querstrebenachse 43 um ihre Längsachse verdrehbar angebracht, wobei die Rundstrebe 33 mit den Längslenkern 18 fest verbunden ist. An der Querstrebe 33 ist die Dämpfungseinheit 10 angelenkt, wie oben beschrieben.The damping unit 10 is mounted via a damping holder 14 with the seat frame 6 at the transverse part 8 in a Dämpfungshalterachse 42 pivotally. With the pivoting gear 11, the damping unit 10 is coupled via a transverse strut 33, which also has a spring holder 32 for the additional damping spring 30. The pivoting gear 11 serves to transmit the movement of the seat frame 6 on the support 12 in a suitable manner so that a smooth adjustment of the support 12 is possible. The pivoting gear 11 is designed as a lever mechanism and connected to the seat frame 6, the base 2 and the support 12 via levers. It has here on each side in the longitudinal direction of the seat / recumbent chassis 1 a slightly downwardly curved trailing arm 18. The trailing arms 18 are each pivotally connected at their rear ends to the respective trailing arm holder 36 in a trailing arm axle 44. The trailing arm 18 are connected to each other in the front third with the cross brace 33 and a round brace 34 lying parallel thereto. The transverse strut 33 is mounted in the trailing arms 18 in a transverse strut axis 43 rotatable about its longitudinal axis, wherein the round strut 33 is fixedly connected to the trailing arms 18. On the transverse strut 33, the damping unit 10 is articulated, as described above.

Jeder Längslenker 18 ist mit seinem vorderen Ende in einer Längslenkerkoppelachse 45 sowohl mit einem Lenkhebel 19 als auch mit einem Schwenkhebel 20 verschwenkbar gekoppelt. Die Lenkhebel 19 sind mit ihren anderen Enden jeweils mit dem Sitzrahmen 6 über Lenkhebelhalter 15 an dem Frontteil 9 in Lenkhebelachsen 46 verschwenkbar verbunden. Die Lenkhebelhalter 15 weisen dabei nach hinten und sind mit dem Sitzrahmen 6 jeweils über eine Strebe 16 fest verbunden. Die Schwenkhebel 20 weisen in ihrem mittleren Bereich seitliche Ausnehmungen auf, welche zur Zusammenwirkung mit Anschlägen, z.B. Anschlagelement 37 und Frontteil 9, in Endlagen der Stütze 12 bestimmt sind. Die Schwenkhebel 20 sind an ihren vorderen Enden jeweils in einer Anlenkachse 47 an einen Stützenrahmen 21 verschwenkbar angelenkt.Each trailing arm 18 is pivotally coupled with its front end in a trailing arm coupling axle 45 both with a steering lever 19 and with a pivot lever 20. The steering levers 19 are pivotally connected at their other ends to the seat frame 6 via steering lever holder 15 on the front part 9 in steering lever axles 46. The steering arm holder 15 point to the rear and are with the Seat frame 6 each firmly connected via a strut 16. The pivot lever 20 have in their central region lateral recesses, which are intended to cooperate with stops, such as stop element 37 and front part 9, in end positions of the support 12. The pivot lever 20 are articulated at their front ends in each case in a pivot axis 47 to a support frame 21 pivotally.

Der Stützenrahmen 21 der Stütze 12 ist in einer Schwenkachse 48, die über Schwenkachsenhalter 17 an der Vorderseite des Frontteils 9 des Sitzrahmens 6 gehalten ist, verschwenkbar angebracht. Der Stützenrahmen 21 ist in Längsrichtung des Sitz-/Liegemöbelchassis 1 auf beiden Seiten mit Auszugelementen 22 verbunden, die eine Stützenplatte 23 in Längsrichtung des Sitz-/Liegemöbelchassis 1 verschiebbar tragen. Die Auszugelemente 22 sind als Teilauszugelemente in äußerst schmaler stabiler Bauweise ausgelegt und ermöglichen einen kompakten und schmalen Aufbau. Die Stützenplatte 23 ist über ein Stützengetriebe 13 mit dem Sitzrahmen 6 derart gekoppelt, dass das Stützengetriebe 13 die Stützenplatte 23 in der ausgefahrenen Position der Stütze 12 in Längsrichtung des Sitz-/Liegemöbelchassis 1 nach vorn verstellt, d.h. somit die Stütze 12 verlängert, und in eingefahrener Position der Stütze 12 die Stützenplatte 23 bis zur Schwenkachse 48 hin verstellt (eingefahrene Position siehe u.a. Fig. 4). Dazu weist das Stützengetriebe 13 einen Antriebshebel 25 auf, der mit seinem hinteren Ende mit einem fest an der Unterseite des Frontteils 9 des Sitzrahmens 6 angebrachten Antriebshebelhalter 24 in einer Antriebsachse 49 verschwenkbar verbunden ist. Das andere Ende dieses Antriebshebels 25 ist mit einem Ende eines Antriebsschiebers 26 in einer Schieberachse 50 verschwenkbar gekoppelt. Der Antriebsschieber 26 ist in dem Stützenrahmen 21 in Längsrichtung des Sitz-/Liegemöbelchassis 1 verschiebbar geführt, über eine Anlenkung 54 mit einer Stützenhaltefeder 29 mit dem Stützenrahmen 21 gekoppelt und an seinem vorderen Ende über eine Schieberkoppelachse 51 mit einem ersten Hebel 27 verschwenkbar gekoppelt. Dabei ist die Schieberkoppelachse 51 in Langlöchern des Stützenrahmens 21 und des ersten Hebels 27 geführt. Weitere Führungen mit zugehörigen Führungsbolzen können vorgesehen sein. Die Stützenhaltefeder 29 dient dazu, die Stützenplatte 23 in der eingefahrenen Position in die Endposition in einem kleinen Abstand zur Schwenkachse 48 zu ziehen. Der erste Hebel 27 ist an seinem hinteren Ende im Bereich der Schieberkoppelachse 51 in einer Ebene parallel zur Stützenplatte 23 gekröpft ausgebildet. Das vordere Ende des ersten Hebels 27 ist verschwenkbar in einer Verbindungsachse 52 mit einem hinteren Ende eines zweiten Hebels 28 gekoppelt, wobei das vordere Ende des zweiten Hebels 28 mit der Stützenplatte 23 in einer Stützenachse 53 verschwenkbar angelenkt ist. Dieses vordere Ende des zweiten Hebels 28 ist zur Stützenplatte 23 hin gekröpft. Der Stützenrahmen 21 ist mit einer Abdeckplatte 38 versehen.The support frame 21 of the support 12 is pivotally mounted in a pivot axis 48 which is held on pivot axis holder 17 at the front of the front part 9 of the seat frame 6. The support frame 21 is connected in the longitudinal direction of the seat / reclining furniture chassis 1 on both sides with pull-out elements 22 which carry a support plate 23 in the longitudinal direction of the seat / reclining chassis 1 slidably. The pull-out elements 22 are designed as partial pullout elements in extremely narrow stable construction and allow a compact and narrow structure. The support plate 23 is coupled via a support gear 13 with the seat frame 6 such that the support gear 13, the support plate 23 in the extended position of the support 12 in the longitudinal direction of the seat / reclining chassis 1 moves forward, ie thus extends the support 12, and in Retracted position of the support 12, the support plate 23 is adjusted to the pivot axis 48 back (retracted position see, inter alia Fig. 4 ). For this purpose, the support gear 13 has a drive lever 25, which is connected at its rear end with a fixedly attached to the underside of the front part 9 of the seat frame 6 drive lever holder 24 in a drive axle 49 pivotally. The other end of this drive lever 25 is pivotally coupled to one end of a drive slide 26 in a slide axis 50. The drive slide 26 is slidably guided in the support frame 21 in the longitudinal direction of the seat / reclining furniture chassis 1, coupled via an articulation 54 with a support retaining spring 29 with the support frame 21 and pivotally coupled at its front end via a Schieberkoppelachse 51 with a first lever 27. Here is the slide coupling axis 51 guided in oblong holes of the support frame 21 and the first lever 27. Other guides with associated guide pins can be provided. The support holding spring 29 serves to pull the support plate 23 in the retracted position to the end position at a small distance from the pivot axis 48. The first lever 27 is formed at its rear end in the region of the Schieberkoppelachse 51 in a plane parallel to the support plate 23 cranked. The front end of the first lever 27 is pivotally coupled in a connecting axis 52 with a rear end of a second lever 28, wherein the front end of the second lever 28 is pivoted to the support plate 23 in a support shaft 53 pivotally. This front end of the second lever 28 is bent toward the support plate 23. The support frame 21 is provided with a cover plate 38.

Wird der Sitzrahmen 6 aus der in Fig. 2 gezeigten ausgefahrenen Position der Stütze 12 nach vorn in die erste Stellung bewegt, welche in einem relativ g so überträgt er diese Bewegung über die Schwenkachse 48, die mit ihm fest verbunden ist, auf das Schwenkgetriebe 11 derart, dass die Schwenkachse 48 nach vorn bewegt wird. Mittels der Schwenkhebel 20, die sowohl über die Lenkhebel 19 als auch die Längslenker 18 mit dem feststehenden Untergestell 2 verbunden sind, wird dann die Stütze 12 in die eingefahrene Position eingeklappt. Das heißt, in der Fig. 2 gegen den Uhrzeigersinn nach hinten geklappt. Dabei wird die Relativbewegung des Sitzrahmens 6 zum Untergestell 2 durch die Dämpfungsfeder 30 unterstützt und die Gasfeder dämpft als Dämpfungselement 31 hierbei die Bewegung, insbesondere die Endbewegung.If the seat frame 6 from the in Fig. 2 shown extended position of the support 12 moves forward in the first position, which in a relatively g so he transmits this movement via the pivot axis 48 which is fixedly connected to him, on the pivot gear 11 such that the pivot axis 48 is moved forward , By means of the pivot lever 20, which are connected via both the steering lever 19 and the trailing arm 18 with the fixed base 2, then the support 12 is folded into the retracted position. That is, in the Fig. 2 folded counterclockwise to the rear. In this case, the relative movement of the seat frame 6 is supported to the undercarriage 2 by the damping spring 30 and the gas spring attenuated as a damping element 31 in this case the movement, in particular the end movement.

Bei diesem Einklapp- oder Einschwenkvorgang wird das Stützengetriebe 13 mittels des um die Antriebsachse 49 verschwenkten Antriebshebels 25 so verstellt, dass die Stützenplatte 23 zur Schwenkachse 48 hin verschoben bzw. eingezogen wird und einen kleinen Abstand zur Schwenkachse 48 einnimmt. Dabei wird die Stützenhaltefeder 29 gespannt.In this Einklapp- or Einschwenkvorgang the support gear 13 is adjusted by means of the drive shaft 49 pivoted about the drive lever 25 so that the support plate 23 is displaced or retracted to the pivot axis 48 and a small distance from the pivot axis 48 occupies. In this case, the support holding spring 29 is tensioned.

Fig. 3b illustriert dazu eine Seitenansicht des Ausführungsbeispiels nach Fig. 2 auf einem Plattenelement 62. Das Untergestell 2 ist auf einem zylindrischen Fuß 39 auf dem Plattenelement 62 verdrehbar aufgebracht. Es ist die ausgefahrene Position der Stütze 12 bzw. der Stützenplatte 23 gezeigt. Die Stützenplatte 23 ist nur um einen kleinen Winkel aus der Ebene mit dem Sitzrahmen 6 verstellt. Fig. 3a veranschaulicht deutlich, dass die Dämpfungsfeder 30 als Zugfeder parallel zum Dämpfungselement 31 angeordnet ist, wobei sie in der gezeigten ausgefahrenen Position gespannt ist. Es ist in Fig. 3b zu erkennen, dass der Sitzrahmen 6 in dieser Position über die Standhebel 4 und 5 nach hinten in die zweite Stellung verschwenkt und geneigt ist. Fig. 3a shows a perspective view of the seat / recumbent chassis 1 in plan view. A back part is not shown. Fig. 3b Illustrates thereto a side view of the embodiment according to Fig. 2 on a plate member 62. The base 2 is rotatably mounted on a cylindrical foot 39 on the plate member 62. It is the extended position of the support 12 and the support plate 23 is shown. The support plate 23 is adjusted only by a small angle from the plane with the seat frame 6. Fig. 3a clearly illustrates that the damping spring 30 is arranged as a tension spring parallel to the damping element 31, wherein it is stretched in the extended position shown. It is in Fig. 3b to recognize that the seat frame 6 is pivoted in this position on the stand lever 4 and 5 to the rear in the second position and inclined.

In Fig. 4a und 4b ist die eingefahren Position der Stütze 12 dargestellt. Fig. 4a ist eine perspektivische Ansicht und Fig. 4b eine Seitenansicht des Ausführungsbeispiels des erfindungsgemäßen Sitz-/Liegemöbelchassis 1.In Fig. 4a and 4b the retracted position of the support 12 is shown. Fig. 4a is a perspective view and Fig. 4b a side view of the embodiment of the invention seat / reclining furniture chassis. 1

In dieser Position ist der Sitzrahmen 6 mit den Standhebeln 4 und 5 gegenüber dem Untergestell 2 bzw. Seitenarmen 3 des Untergestells 2 nach vorn in die erste Stellung geschwenkt. Die Stütze 12 ist mit ihrer Stützenplatte 23 vollständig eingeklappt und hat im Vergleich zu der ausgefahrenen Position (Fig. 3a-3b) einen Verschwenkwinkel von fast 180° ausgeführt. Dabei ist die Stützenplatte 23 in Richtung zur Schwenkachse 48 eingezogen. Ihr Abstand zur Schwenkachse ist hier wesentlich kleiner als in der ausgefahrenen Position. Diese Version ist besonders für Sitzmöbel geeignet, bei welchen ein großer Freiraum unter dem Sitz sein soll. Die besonders schmale Ausgestaltung des Sitz-/Liegemöbelchassis 1 in der Höhe erlaubt viele Designmöglichkeiten.In this position, the seat frame 6 is pivoted with the stand levers 4 and 5 relative to the base frame 2 and side arms 3 of the undercarriage 2 forward in the first position. The support 12 is completely folded with its support plate 23 and has compared to the extended position ( Fig. 3a-3b ) executed a pivoting angle of almost 180 °. In this case, the support plate 23 is retracted in the direction of the pivot axis 48. Their distance to the pivot axis is much smaller here than in the extended position. This version is particularly suitable for seating furniture in which a large space should be under the seat. The particularly narrow design of the seat / reclining chassis 1 in height allows many design options.

Eine Draufsicht auf das Sitz-/Liegemöbelchassis 1 in eingefahrener Position der Stütze 12 zeigt Fig. 5. Hierbei ist die Endstellung der Hebel 27 und 28 zusammen mit dem Antriebsschieber 26 und der zugehörigen Achsen 51, 52 und 53 zu erkennen. Die Dämpfungsfeder 30 ist nicht eingehängt. Das Dämpfungselement 31 ist mit dem Dämpfungshalter 14 außermittig angeordnet, um Raum für die noch nicht eingehängte Dämpfungsfeder 30 zu schaffen. Hier ist zu sehen, dass die Streben 16 zur Stabilisierung der Lenkhebelhalter 15 an den vorderen Enden der Seitenteile 7 des Sitzrahmens 6 angebracht sind. Die Stützenplatte 23 ist hier in ihrer Geometrie nach vorne enger werdend ausgebildet. Aufgrund der schmalen Bauweise der Hebelgetriebe ist ein verhältnismäßig großer Bauraum in der Mitte für die Dämpfungseinheit geschaffen. Dadurch ist es möglich, in dem gleichen Sitz-/Liegemöbelchassis 1 anstelle des Dämpfungselementes 31 in Gestalt einer Gasfeder und der Dämpfungsfeder 30 ein motorisches Antriebselement, wie beispielsweise einen elektromotorischen Antrieb, einzusetzen. Dieser ist praktisch gegen die Gasfeder und Dämpfungsfeder 30 austauschbar, ohne dass Änderungen an des Sitz-/Liegemöbelchassis 1 notwendig sind (siehe auch Fig. 8a-8b). Hierzu können zusätzliche Anbringungslöcher im Dämpfungshalter 14 angebracht sein, um eine große Variabilität zu erhalten.A plan view of the seat / recumbent chassis 1 in the retracted position of the support 12 shows Fig. 5 , in this connection the end position of the levers 27 and 28 together with the drive slide 26 and the associated axes 51, 52 and 53 can be seen. The damping spring 30 is not suspended. The damping element 31 is eccentrically arranged with the damping holder 14 in order to create space for the not yet suspended damping spring 30. Here it can be seen that the struts 16 are mounted to stabilize the steering lever holder 15 at the front ends of the side parts 7 of the seat frame 6. The support plate 23 is designed to be narrower in terms of geometry in this case. Due to the narrow design of the lever mechanism, a relatively large space in the middle of the damping unit is created. This makes it possible, in the same seat / recumbent chassis 1 instead of the damping element 31 in the form of a gas spring and the damping spring 30, a motor drive element, such as an electric motor drive to use. This is practically interchangeable with the gas spring and damper spring 30, without changes to the seat / recumbent chassis 1 are necessary (see also Fig. 8a-8b ). For this purpose, additional mounting holes may be mounted in the damping holder 14 to obtain a large variability.

Fig. 6a und 6b zeigen eine perspektivische Ansicht und eine Seitenansicht einer Variation des Ausführungsbeispiels des erfindungsgemäßen Sitz-/Liegemöbelchassis 1 in eingefahrener Position auf dem Plattenelement 62 ohne Rückenteil. In dieser Variation ist der Schwenkwinkel der Stütze 12 um die Schwenkachse mit 60° ausgebildet. Dies ist in einfacher Weise möglich, indem z.B. die Schwenkhebel 20 in den Anlenkachsen 47 an anderer Stelle des Stützenrahmens 21 in vorgefertigte Positionen angebracht werden. Auch andere, einfache Änderungen können dazu vorgenommen werden. Fig. 6a and 6b show a perspective view and a side view of a variation of the embodiment of the invention seat / recumbent chassis 1 in the retracted position on the plate member 62 without back part. In this variation, the pivot angle of the support 12 is formed about the pivot axis at 60 °. This is possible in a simple manner, for example by the pivot lever 20 are mounted in the pivot axes 47 elsewhere in the support frame 21 in prefabricated positions. Other, simple changes can be made.

Fig. 7a zeigt eine Seitenansicht des Ausführungsbeispiels des erfindungsgemäßen Sitz-/Liegemöbelchassis 1 in ausgefahrener Position, Fig. 7b stellt die eingefahrene Position dar. Fig. 7a und 7b dienen zur Erläuterung von Schwenkradien bei einer Verschwenkung der Stütze 12 ca. 180°. Fig. 7a shows a side view of the embodiment of the invention seat / reclining furniture chassis 1 in the extended position, Fig. 7b represents the retracted position. FIG. 7a and 7b serve to explain swivel radii at a pivoting of the support 12 about 180 °.

In Fig. 7a ist der Sitzrahmen 6 in die zweite Stellung nach hinten mittels der Standhebel 4, 5 um die Standlenkerachsen 40 in einem Sitzteilschwenkwinkel 59 verschwenkt. Bei einer Verschwenkung der Stütze 12 bzw. der Stützenplatte 23 um die Schwenkachse 48 verschwenkt die Stützenplatte 23 auf einem Stützteilfixradius 55, welcher fest steht. Eine Realkurve 56 gibt den Weg der Stützenplatte 23 zusammen mit dem Einziehen in Richtung auf die Schwenkachse 48 hin an, wobei das Sitz-/Liegemöbelchassis zum Boden hin keine Bewegung ausführt. Schließlich zeigt eine Bewegungskurve 57 die Bewegung der Stütze 12 in Bezug auf den Sitzrahmen 6, der dabei als Basis dient, an. Fig. 7b stellt die eingefahrene Position nach Verschwenkung der Stütze 12 um ca. 180° um die Schwenkachse 48 dar. Zwischen dem Endpunkt des Stützteilfixradius 55 und dem Endpunkt der Bewegungskurve 57 unterhalb der Seitenarme 3 des Untergestells 2 ist eine Differenz x in Gestalt eines Differenzwegs 58 zu verzeichnen. Dieser Differenzweg 58 wird mit Hilfe der Stützenhaltefeder 29 durchlaufen, so dass der Endpunkt der Bewegungskurve 57 sicher erreicht wird. Das hat zur Folge, dass die eingeklappte Stütze 12 in ihre eingefahrene Position durch die Stützenhaltefeder 29 hineingezogen wird und dort sicher verbleibt, ohne dass die Stützenplatte 23 nach unten herunterhängt und einen Spalt freigibt.In Fig. 7a is the seat frame 6 in the second position to the rear by means of the stand lever 4, 5 is pivoted about the pivot links 40 in a seat part pivot angle 59. Upon pivoting of the support 12 or the support plate 23 about the pivot axis 48, the support plate 23 pivots on a Stützteilfixradius 55, which is fixed. A real curve 56 indicates the path of the support plate 23 along with the retraction in the direction of the pivot axis 48, the seat / reclining chassis performing no movement towards the ground. Finally, a movement curve 57 indicates the movement of the support 12 with respect to the seat frame 6, which serves as a base. Fig. 7b represents the retracted position after pivoting of the support 12 by about 180 ° about the pivot axis 48. Between the end of the Stützteilfixradius 55 and the end point of the movement curve 57 below the side arms 3 of the undercarriage 2 is a difference x in the form of a differential path 58 recorded , This differential path 58 is traversed by means of the support holding spring 29, so that the end point of the movement curve 57 is reached safely. This has the consequence that the retracted support 12 is pulled into its retracted position by the support retaining spring 29 and remains there safely, without the support plate 23 hangs down and releases a gap.

Fig. 8a-8b zeigen eine perspektivische Ansicht und eine Seitenansicht einer weiteren Variation des Ausführungsbeispiels des erfindungsgemäßen Sitz-/Liegemöbelchassis 1 in einem Sitzmöbel 60 nach Fig. 1. Hierbei ist das Dämpfungselement 31 durch ein motorisches Antriebselement 64, beispielsweise einen elektromotorischen Verstellantrieb, ausgetauscht oder ersetzt. Das Sitz-/Liegemöbelchassis 1 ist dazu nicht auszutauschen, nur ein einfacher Austausch des Dämpfungselementes 31 ist notwendig. Schließlich zeigen Figuren 9a-9b und 10a-10b weitere Variationen des Sitzmöbels 60, wobei der Sitzrahmen 6 schon mit einer Federung versehen ist. Fig. 9a zeigt eine mitlaufende Armlehne 63, die mit dem Sitzrahmen 6 über geeignete Verbindungswinkel verbunden ist. Die zweite Armlehne 63 ist nicht gezeigt, aber leicht vorstellbar. In Fig. 9b ist eine Seitenansicht gezeigt. Fig. 8a-8b show a perspective view and a side view of a further variation of the embodiment of the inventive seat / reclining furniture chassis 1 in a chair 60 after Fig. 1 , Here, the damping element 31 is replaced or replaced by a motor drive element 64, for example, an electric motor adjustment. The sitting / reclining furniture chassis 1 is not replaced, only a simple replacement of the damping element 31 is necessary. Finally show FIGS. 9a-9b and 10a-10b other variations of the chair 60, wherein the seat frame 6 is already provided with a suspension. Fig. 9a shows a follower arm 63, which is connected to the seat frame 6 via suitable connection angle. The second armrest 63 is not shown but is easy to imagine. In Fig. 9b a side view is shown.

Im Gegensatz dazu zeigt Fig. 10a eine feststehende Armlehne 63 (auch hier ist die zweite Armlehne nicht dargestellt). Diese ist mit dem Untergestell über passende Verbindungsstücke verbunden.In contrast, shows Fig. 10a a fixed armrest 63 (again, the second armrest is not shown). This is connected to the base frame via suitable connecting pieces.

Weitere Ausführungen im Rahmen der Erfindung sind möglich, die beschriebenen Beispiele grenzen die Erfindung nicht ein.Other embodiments within the scope of the invention are possible, the examples described do not limit the invention.

So kann beispielsweise die Stützenplatte 23 rechtwinklig ausgeführt sein.Thus, for example, the support plate 23 may be executed at right angles.

Die Stützenhaltefeder 29 kann in dem Stützengetriebe 13 auch an anderer Stelle mit Kopplung mit anderen Elementen angeordnet sein. Dazu kann sie auch entsprechend umgelenkt sein, je nach Platzbedarf und Einbauraum. Auch eine Druckfeder ist in entsprechender Anlenkung und Kraftumkehr geeignet.The support holding spring 29 may be arranged in the support gear 13 at another location with coupling to other elements. For this purpose, it can also be deflected accordingly, depending on the space required and installation space. Also, a compression spring is suitable in appropriate articulation and force reversal.

Es ist auch denkbar, dass mehr als eine Dämpfungsfeder 30 verwendet wird.It is also conceivable that more than one damping spring 30 is used.

Selbstverständlich können auch mehr als Stützenhaltefeder 29 eingesetzt werden.Of course, more than support retaining spring 29 can be used.

Als motorisches Antriebselement 64 kann auch eine auslösbare Gasfeder (oder mehrere) zum Einsatz kommen.As a motor drive element 64, a releasable gas spring (or more) can be used.

In so genannten Mehrsitzern können mehrere Sitz-/Liegemöbelchassis 1 nebeneinander verwendet werden.In so-called multi-seat multiple seat / reclining chassis 1 can be used side by side.
