- the racks 131 are arranged at a distance from one another and are connected to one another via a first cross strut 133.
- the cross strut 133 is according to Figures 6 and 7 for example, arranged in an end region of the racks 131.
- FIG. 6 shows the translation mechanism 130 corresponding to the first position of the headrest 120. That is, when the headrest 120 is retracted.
- FIG. 7 shows the translation mechanism 130 corresponding to the second position of the headrest 120. That is, when the headrest 120 is extended. In this position, the second crossbar 134 is in its uppermost position.
- the second crossbar 134 can assume a variety of positions between the top and bottom positions, and thus the headrest 120 can be locked (locked) at different heights.
- the locking fitting 135 can comprise 23 locking positions.
- the height difference between the top position of the second crossbar 134 and the bottom position of the second crossbar 134 can be 15 cm. Other height differences are also conceivable.
- the headrest 120 In order to transfer the headrest 120 from a lower position to a higher position, it is sufficient to pull the headrest 120 upwards. In order to transfer the headrest 120 from a position further up to a position further down, the headrest 120 must first be brought into its second position (uppermost position of the second cross strut 134) in order to release the locking fitting 135 from its locking state, so that the headrest 120 can then move downwards into its first position (lowest position of the second crossbar 134).
- the backrest device 100 can include a translation mechanism 140 for a motor-driven linear adjustment of the headrest 120.
- This translation mechanism 140 is in its installed state in the base body of the backrest 110 Figure 8 shown.
- Figure 9 shows the translation mechanism 140 Figure 8 alone.
- the translation mechanism 140 includes a bracket 141 which is provided for fastening the translation mechanism 140 in the backrest 110.
- a motor 143 is attached to the bracket 141 via a linear guide 142.
- the linear guide 142 extends along the translation axis T.
- the linear guide serves to guide a carrier 144, which in the embodiment of Figures 9 to 12 is designed in two parts.
- the carrier 144 includes a first carrier part 1441, which is connected to a crossbar 145 to which the headrest is attached, and a second carrier part 1442, which is linearly displaceable by the motor 143.
- the crossbar 145 extends transversely to the translation axis T and along the width of the headrest 124.
- Figure 9 illustrates the translation mechanism 140 in a configuration that corresponds to the first position of the headrest 120.
- Figure 10 shows the translation mechanism 140 Figure 9 without the bracket 141 and in a view rotated by 180 ° about the translation axis T.
- Figure 11 shows the translation mechanism 140 Figure 10 , however, the configuration corresponds to that of the second position of the headrest 120.
- the first and second carrier parts 1441, 1442 can be clearly seen.
- the motor 143 drives the second carrier part 1442.
- the first carrier part 1441 which is connected to the second carrier part 1442 via a releasable connection, moves together with the second carrier part 1442 ( Figures 10 and 11 ).
- the movement of the second support part 1442 can be decoupled from that of the headrest 120 (connected to the first support part 1441 via the cross strut 145) by applying a force ( Figure 12 ).
- the detachable connection is such that, on the one hand, the first carrier part 1441 and the headrest 120 connected to it are displaceable with the second carrier part 1442 when the first carrier part 1441 and the second carrier part 1442 are connected to one another by means of the detachable connection, and that on the other hand first carrier part 1441 and the headrest 120 connected to it cannot be displaced with the second carrier part 1442 if the first carrier part 1441 and the second carrier part 1442 are not connected to one another by means of the releasable connection.
- the detachable connection By releasing the detachable connection, it is possible to prevent the headrest 120, the cross strut 145 and the first support part 1441 from coming into contact with the second support part when the motor 143 is in operation, which causes a linear adjustment of the second support part 1442 in the direction of the first position of the headrest 120 1442 move. This can, for example, prevent a user who is holding the headrest 120 from being caught by the lowering headrest 120 injured especially trapped.
- the detachable connection therefore has the function of a pinch protection.
- the detachable connection is designed, for example, as a magnetic connection.
- the magnetic connection can be such that it releases with a counterforce of 9 kg, so that although the second carrier part 1442 can be adjusted linearly by the motor 142, the first carrier part 1441 does not move with the second carrier part 1442.
- the translation mechanism 130, 140 is arranged in the receptacle 113 of the backrest 110.

Description
Die Erfindung betrifft eine Lehnenvorrichtung für ein Möbelstück, das zum Sitzen und/oder zum Liegen geeignet ist. Die Erfindung betrifft auch ein Sitz- und/oder Liegemöbelstück mit einer solchen Lehnenvorrichtung und mit einem Sitz- beziehungsweise Liegeelement.The invention relates to a backrest device for a piece of furniture that is suitable for sitting and/or lying down. The invention also relates to a piece of seating and/or reclining furniture with such a backrest device and with a seating or reclining element.
Moderne Sitzmöbel beziehungsweise Liegemöbel sehen gelegentlich Verstellmöglichkeiten vor, um den Komfort für den Benutzer zu erhöhen. Die Verstellmöglichkeiten betreffen beispielsweise Kopf oder Rücken des Benutzers. Die erfindungsgemäße Lehnenvorrichtung zielt insbesondere darauf ab, die Möglichkeit zum Abstützen von Kopf und Rücken eines Benutzers bedarfsgerecht zu gestalten und dennoch ein ansprechendes Erscheinungsbild zu bieten.Modern seating or reclining furniture occasionally provides adjustment options to increase comfort for the user. The adjustment options affect, for example, the user's head or back. The backrest device according to the invention aims in particular to provide the possibility of supporting the head and back of a user according to needs and still offer an attractive appearance.
Das Sitz- und/oder Liegemöbelstück (Möbelstück) kann insbesondere ein Polstermöbelstück, wie beispielsweise ein Sessel, ein Sofa, eine Couch, eine Recamiere oder eine Chaiselongue sein. Die Lehnenvorrichtung umfasst dementsprechend Polsterelemente.The piece of seating and/or lying furniture (piece of furniture) can in particular be a piece of upholstered furniture, such as an armchair, a sofa, a couch, a chaise lounge or a chaise longue. The backrest device accordingly includes upholstery elements.
Die erfindungsgemäße Lehnenvorrichtung umfasst eine Rückenlehne und eine Kopfstütze. Die Kopfstütze ist gegenüber der Rückenlehne zwischen einer ersten (eingefahrenen) Position und einer zweiten (ausgefahrenen) Position verstellbar. Konkret handelt es sich um die Möglichkeit der Linearverstellung entlang einer Translationsachse. Die Kopfstütze weist einen Überlappungsabschnitt auf, der stets mit einem Teil der Rückenlehne überlappt, so dass zwischen der Rückenlehne und der Kopfstütze keine Lücke entsteht, wenn sich die Kopfstütze in der ersten Position, der zweiten Position und einer Zwischenposition (zwischen der ersten und der zweiten Position) befindet. Das heißt, dass unabhängig von ihrer Position die Kopfstütze stets mit einem Teil der Rückenlehne überlappt. Je nach Position der Kopfstütze fällt der Bereich der Überlappung entlang der Translationsachse betrachtet größer oder kleiner aus. Je geringer der Überlappungsbereich ist, umso mehr verlängert die Kopfstütze die Rückenlehne entlang der Translationsachse. Die Linearverstellung ermöglicht also eine Anpassung der Lehnenvorrichtung an die Körpergröße des Benutzers. Da in keiner Position der Kopfstütze eine Lücke zwischen Kopfstütze und Rückenlehne entsteht, ist das Erscheinungsbild harmonisch und wird der modulare Aufbau nicht betont.The backrest device according to the invention comprises a backrest and a headrest. The headrest is adjustable relative to the backrest between a first (retracted) position and a second (extended) position. Specifically, this is the possibility of linear adjustment along a translation axis. The headrest has an overlap section which always overlaps with part of the backrest, so that There is no gap between the backrest and the headrest when the headrest is in the first position, the second position and an intermediate position (between the first and second positions). This means that regardless of its position, the headrest always overlaps with part of the backrest. Depending on the position of the headrest, the area of overlap is larger or smaller when viewed along the translation axis. The smaller the overlap area, the more the headrest extends the backrest along the translation axis. The linear adjustment therefore enables the backrest device to be adapted to the user's body size. Since there is no gap between the headrest and the backrest in any position of the headrest, the appearance is harmonious and the modular structure is not emphasized.
Gemäß einer Ausführungsform ist der Überlappungsabschnitt flächig ausgebildet und erstreckt sich in einer Haupterstreckungsebene. Der Überlappungsabschnitt erstreckt sich über die gesamte Breite der Kopfstütze. Dabei überlappt der Überlappungsabschnitt zumindest in Blickrichtung senkrecht zur Haupterstreckungsebene stets mit einem Teil der Rückenlehne. Der Überlappungsabschnitt kann bezüglich der Rückenlehne derart angeordnet sein, dass der Überlappungsabschnitt einen Teil der Rückenlehne verdeckt (aus einer Blickrichtung auf die einem Benutzer zugewandten Seite betrachtet).According to one embodiment, the overlap section is flat and extends in a main extension plane. The overlap section extends over the entire width of the headrest. The overlap section always overlaps with a part of the backrest, at least in the viewing direction perpendicular to the main extension plane. The overlapping section can be arranged with respect to the backrest in such a way that the overlapping section covers a part of the backrest (viewed from a viewing direction of the side facing a user).
Die Translationsachse kann in der Haupterstreckungsebene des Überlappungsabschnitts der Kopfstütze liegen. Alternativ können die Translationsachse und die Haupterstreckungsebene einen Winkel kleiner als 90° einschließen. Insbesondere kann die Translationsachse in der Haupterstreckungsebene des Überlappungsabschnitts liegen. Bei bestimmungsgemäßer Anordnung der Lehnenvorrichtung kann die Translationsachse vertikal ausgerichtet sein.The translation axis can lie in the main plane of extension of the overlapping section of the headrest. Alternatively, the translation axis and the main extension plane can enclose an angle of less than 90°. In particular, the translation axis can lie in the main extension plane of the overlap section. If the backrest device is arranged as intended, the translation axis can be aligned vertically.
Gemäß einer Ausführungsform sind zwischen der ersten Position und der zweiten Position entlang der Translationsachse eine Vielzahl von Zwischenpositionen vorgesehen, die durch lineares Verstellen der Kopfstütze gegenüber der Rückenlehne entlang der Translationsachse einstellbar sind. Die Kopfstütze kann in jeder der ersten Position, der zweiten Position und jeder Zwischenpositionen feststellbar oder einrastbar sein.According to one embodiment, a plurality of intermediate positions are provided between the first position and the second position along the translation axis, which can be adjusted by linearly adjusting the headrest relative to the backrest along the translation axis. The headrest can be lockable or lockable in any of the first position, the second position and any intermediate positions.
Zusätzlich zu der Linearverstellung kann die Kopfstütze um eine Rotationsachse schwenkbar sein. Dabei kann die Rotationsachse im Wesentlichen senkrecht zu der Translationsachse gerichtet sein und sich entlang der Breite der Kopfstütze erstrecken. Die Schwenkbarkeit der Kopfstütze ermöglicht, die Neigung der Kopfstütze gegenüber der Rückenlehne einzustellen.In addition to the linear adjustment, the headrest can be pivotable about an axis of rotation. The rotation axis can be directed essentially perpendicular to the translation axis and extend along the width of the headrest. The swivelability of the headrest makes it possible to adjust the inclination of the headrest relative to the backrest.
Je nach Position der Kopfstütze entlang der Translationsachse kann so die Neigung für den Kopf oder für den Oberkörper und den Kopf insgesamt eingestellt werden.Depending on the position of the headrest along the translation axis, the inclination for the head or for the upper body and the head as a whole can be adjusted.
Es ist denkbar, dass die Linearverstellung manuell erfolgt. So kann beispielsweise durch Druck auf die Lehnenvorrichtung, entlang der Translationsachse von unten nach oben, die Kopfstütze nach oben bewegt werden, um in eine der Zwischenpositionen oder in die zweite Position einzurasten. Zwecks Linearverstellung kann mindestens eine Zahnstange vorgesehen sein, die mit mindestens einem Zahnrad zusammenwirkt. Die mindestens eine Zahnstange ist parallel zur Translationsachse ausgerichtet. Um die Rastfunktion zu erreichen kann ein Rastbeschlag vorgesehen sein, der das Verrasten in einer der genannten Positionen ermöglichtIt is conceivable that the linear adjustment takes place manually. For example, by pressing on the backrest device along the translation axis from bottom to top, the headrest can be moved upwards in order to lock into one of the intermediate positions or into the second position. For the purpose of linear adjustment, at least one rack can be provided, which interacts with at least one gear. The at least one rack is aligned parallel to the translation axis. In order to achieve the locking function, a locking fitting can be provided which enables locking in one of the positions mentioned
Alternativ oder zusätzlich zur manuellen Linearverstellung kann eine motorgetriebene Linearverstellung vorgesehen sein. Zu diesem Zweck kann die Lehnenvorrichtung einen Motor zur Linearverstellung der Kopfstütze umfassen, wobei der Motor über einen Träger auf die Kopfstütze einwirkt. Der Träger kann einen ersten Trägerteil, der mit der Kopfstütze fest verbunden ist, und einen zweiten Trägerteil, der durch den Motor linear verschiebbar ist, umfassen. Dabei können der erste Trägerteil und der zweite Trägerteil lösbar miteinander verbunden sein. Hierdurch können die beiden Trägerteile unter Umständen unabhängig voneinander bewegt werden. Insbesondere kann die lösbare Verbindung dergestalt sein, dass der erste Trägerteil und die mit ihm verbundene Kopfstütze mit dem zweiten Trägerteil verschiebbar sind, wenn der erste Trägerteil und der zweite Trägerteil mittels der lösbaren Verbindung miteinander verbunden sind, und dass der erste Trägerteil und die mit ihm verbundene Kopfstütze nicht mit dem zweiten Trägerteil verschiebbar sind, wenn der erste Trägerteil und der zweite Trägerteil nicht mittels der lösbaren Verbindung miteinander verbunden sind. Diese Ausgestaltung kann bei Betrieb des Motors, der im Begriff ist, eine Linearverstellung des zweiten Trägerteils von der zweiten Position in die erste Position zu bewirken, verhindern, dass sich die Kopfstütze und der erste Trägerteil mit dem zweiten Trägerteil bewegen und beispielsweise einen Benutzer, der die Kopfstütze festhält, verletzen. Beispielsweise kann die lösbare Verbindung zwischen dem ersten Trägerteil und dem zweiten Trägerteil eine Magnetverbindung umfassen.Alternatively or in addition to the manual linear adjustment, a motor-driven linear adjustment can be provided. For this purpose, the backrest device can comprise a motor for linear adjustment of the headrest, the motor acting on the headrest via a carrier. The carrier may comprise a first carrier part, which is firmly connected to the headrest, and a second carrier part, which is linearly displaceable by the motor. The first carrier part and the second carrier part can be detachably connected to one another. This allows the two carrier parts to be moved independently of each other under certain circumstances. In particular, the releasable connection can be such that the first support part and the headrest connected to it are displaceable with the second support part when the first support part and the second support part are connected to one another by means of the releasable connection, and that the first support part and the headrest connected to it connected headrest cannot be moved with the second carrier part if the first carrier part and the second carrier part are not connected to one another by means of the releasable connection. This embodiment can prevent the headrest and the first support part from moving with the second support part and, for example, a user, when the motor is in operation, which is about to effect a linear adjustment of the second support part from the second position to the first position hold the headrest. For example, the detachable connection between the first carrier part and the second carrier part can comprise a magnetic connection.
Aus ästhetischen Gründen kann der Motor verdeckt sein, insbesondere in einer Aufnahme angeordnet sein, die in der Rückenlehne ausgebildet ist.For aesthetic reasons, the motor can be hidden, in particular arranged in a receptacle that is formed in the backrest.
