Abstract
Description
Die Erfindung bezieht sich auf eine neigbare Rückenlehne, insbesondere für einen Bürostuhl, mit einem Schulterbereich, einem Lordosenbereich und einem Beckenbereich, wobei die Rückenlehne in mindestens einem Bereich flexibel ist und an jeweils mindestens einem oberen und unteren Verbindungselement mit einem starren Lehnenrahmen verbunden ist, wobei das obere Verbindungselement als Drehlager und das untere Verbindungselement als Schiebelager ausgebildet ist, und wobei die Flexibilität der Rückenlehne im Lordosenbereich erhöht ist, so dass der Lordosenbereich durch Krümmung vorwölbbar ist.The invention relates to a tiltable backrest, in particular for an office chair, with a shoulder region, a lumbar region and a pelvic area, wherein the backrest is flexible in at least one area and is connected to at least one upper and lower connecting element with a rigid back frame, wherein the upper connecting element is designed as a pivot bearing and the lower connecting element as a sliding bearing, and wherein the flexibility of the backrest is increased in the lumbar region, so that the lumbar region is bulged by curvature.
Im Handel erhältlich ist ein Bürostuhl mit Synchronmechanismus und neigbarer Rückenlehne. Dieser Bürostuhl weist einen starren, gepolsterten Polsterträger auf, welcher sich vom Beckenbereich bis zum Schulterbereich erstreckt. Zusätzlich weist die Rückenlehne eine zum Polsterträger hin flexible Nackenstütze auf, welche über ein Drehlager an einem Lehnenrahmen befestigt ist. Der Polsterträger ist im Beckenbereich ebenfalls am Lehnenrahmen befestigt. Beim Zurücklehnen einer auf dem Stuhl sitzenden Person neigt sich die Rückenlehne und der Lehnenrahmen nach hinten. Dabei sinkt der Schulterbereich der Rückenlehne relativ zum Lehnenrahmen leicht ein. Die Nackenstütze wird durch den Lehnenrahmen gehalten und relativ zum Schulterbereich der Rückenlehne leicht nach vorne gedrückt und stützt dabei den Kopf. Polsterträger und Nackenstütze vollziehen eine Art Klappbewegung. Die Rückenlehne passt sich teilweise der Bewegung der auf dem Stuhl sitzenden und sich zurücklehnenden Person an. Ausser im Schulter- und Nackenbereich ist diese Rückenlehne jedoch relativ starr und kann sich besonders im Lordosenbereich nicht optimal anpassen. Auch entspricht bei einer zurücklehnenden Person der leicht nach vorne gedrückte Kopf keiner entspannten Haltung.Commercially available is an office chair with synchronous mechanism and tilting backrest. This office chair has a rigid, padded cushion support that extends from the pelvic area to the shoulder area. In addition, the backrest has a cushion support towards flexible neck support, which is attached via a pivot bearing on a back frame. The cushion support is also attached to the backrest frame in the pelvic area. When leaning back a person sitting on the chair, the backrest and the back frame tilts backwards. In this case, the shoulder region of the backrest decreases slightly relative to the backrest frame. The neck support is held by the back frame and slightly pushed forward relative to the shoulder region of the backrest, supporting the head. Upholstery and neck support make a kind of folding movement. The backrest adapts in part to the movement of the person sitting on the chair and reclining. Except in the shoulder and neck area, however, this backrest is relatively rigid and can not, especially in the lumbar region optimally adapt. Also, in a reclining person, the head slightly pushed forward does not correspond to a relaxed posture.
In
Aufgabe der Erfindung ist es, eine eingangs genannte neigbare Rückenlehne anzugeben, welche sich während dem Sitzen automatisch und optimal dem Rücken anpasst, unabhängig davon, ob eine Person in aufrechter Haltung sitzt oder zurücklehnt. Dabei soll die Lordose immmer opitmal gestützt sein.The object of the invention is to provide a tiltable backrest mentioned above, which automatically and optimally adapts to the back while sitting, regardless of whether a person sitting upright or leaning back. At the same time the lordosis should always be supported.
Erfindungsgemäss wird diese Aufgabe bei einer neigbaren Rückenlehne der eingangs genannten Art dadurch gelöst, dass das Drehlager an der Rückseite der Rückenlehne knapp unterhalb des Schulterbereiches befestigt ist und die Rückenlehne mit dem oberen Bereich des Lehnenrahmens verbindet, wobei der obere Teil der Rückenlehne in Bezug auf den Lehnenrahmen nach vorne oder nach hinten neigbar ist. Das Schiebelager ist an der Rückseite der Rückenlehne im Beckenbereich befestigt, wobei sich der Beckenbereich der Rückenlehne in Bezug auf den Lehnenrahmen vertikal nach oben oder nach unten frei verschieben kann.According to the invention this object is achieved in a tiltable backrest of the type mentioned above in that the pivot bearing is attached to the back of the back just below the shoulder area and connects the backrest with the upper portion of the back frame, the upper part of the backrest with respect to the Back frame can be tilted forwards or backwards. The sliding bearing is attached to the back of the backrest in the pelvic region, whereby the pelvic region of the backrest can move vertically upwards or downwards in relation to the backrest frame.
Die erfindungsgemässe Anordnung von Drehlager, Schiebelager und erhöhter Flexibilität des Lordosenbereiches führt zu einer Kopplung der Bewegungen der Rückenlehne im Schulterbereich, Lordosenbereich und Beckenbereich. Die Erfindung erlaubt in jeder Sitzposition eine optimale, sich automatisch einstellende Anpassung der Rückenlehne an den Rücken der Person. Je nachdem, wo durch die Person Druck auf die Rückenlehne ausgeübt wird, verformt sich die Rücklehne entsprechend, so dass die Lordose immer gut gestützt ist.The inventive arrangement of pivot bearing, sliding bearing and increased flexibility of the lumbar region leads to a coupling of the movements of the backrest in the shoulder area, lordosis and pelvic area. The invention allows in each seating position an optimal, automatically adjusting adjustment of the backrest to the back of the person. Depending on where the person is applying pressure on the backrest, the backrest deforms accordingly, so that the lordosis is always well supported.
Im unbelasteten Zustand kann die Rückenlehne im Lordosenbereich so vorgeformt sein, dass sie mit einem Winkel zwischen 25 und 30 Grad gebogen ist und dabei im Lordosenbereich vorgewölbt ist.In the unloaded state, the backrest can be preformed in the lumbar region so that it is bent at an angle between 25 and 30 degrees and thereby bulges in the lumbar region.
Durch die erfindungsgemässe Anordnung von Drehlager, flexiblem Lordosenbereich und Schiebelager ergibt sich, dass sich die Rückenlehne beim Einsitzen einer Person durch Druck auf den Lordosenbereich dem Rücken der Person anpasst. Dabei kann, in Bezug auf den unbelasteten Zustand und relativ zum Lehnenrahmen, der Lordosenbereich um 10 bis 20 Grad abgeflacht und nach hinten verlagert sein, der obere Bereich der Rückenlehne oberhalb des Drehlagers nach vorne verlagert sein, und der Beckenbereich der Rückenlehne entlang dem Schiebelager nach unten verschoben sein.Due to the inventive arrangement of pivot bearing, flexible lumbar region and sliding bearing results in that the backrest while sitting a person by pressure on the lordosis adjusts the back of the person. In this case, in relation to the unloaded state and relative to the backrest frame, the lumbar region may be flattened and displaced backwards by 10 to 20 degrees, the upper region of the backrest above the pivot bearing displaced forwards, and the pelvic region of the backrest along the sliding bearing be moved down.
Weiter ergibt sich erfindungsgemäss, dass sich die Rückenlehne beim Zurücklehnen der Person durch Druck auf den Schulterbereich ebenfalls dem Rücken anpasst. Dabei kann, in Bezug auf den unbelasteten Zustand und relativ zum Lehnenrahmen, die Rückenlehne im Lordosenbereich um zusätzliche 10 bis 20 Grad gebogen sein und dabei die Lordosenstütze weiter vorstehen, der obere Bereich der Rückenlehne oberhalb des Drehlagers nach hinten verlagert sein, und der Beckenbereich der Rückenlehne entlang dem Schiebelager nach oben verschoben sein.Furthermore, according to the invention, the backrest likewise adapts to the back when the person reclines through pressure on the shoulder area. In this case, in relation to the unloaded state and relative to the backrest frame, the backrest in the lumbar region can be bent by an additional 10 to 20 degrees while the lumbar support projecting further, the upper region of the backrest above the pivot bearing being displaced to the rear, and the pelvic region of the backrest Backrest along the sliding bearing to be moved upwards.
Die erfindungsgemässe Rückenlehne passt sich beim Einsitzen der jeweiligen Rückenform an und garantiert beim Zurücklehnen eine optimale Stützfunktion im Lordosen und Schulterbereich.The backrest according to the invention adapts when the respective back form is inserted and guarantees an optimal support function in the lordosis and shoulder area when leaning back.
In einer bevorzugten Ausführungsform umfasst die Rückenlehne einen Polsterträger und eine Polsterung, wobei der Polsterträger zwei mit mehreren leistenförmigen Rippen verbundene Seitenholme aufweist, und wobei die Seitenholme im Lordosenbereich, z.B. durch Verjüngung, flexibler sind als im oberen und unteren Bereich. Jeweils ein Drehlager und ein Schiebelager kann als Verbindungselement für den Lehnenrahmen mit dem Polsterträger rückseitig an den Seitenholmen angebracht sein. Der Lehnenrahmen kann zwei diagonale, sich kreuzende Streben aufweisen, welche die oberen und unteren Verbindungselemente miteinander verbindet, wobei die Streben in deren Kreuzungspunkt miteinander verbunden sind.In a preferred embodiment, the backrest comprises a cushion support and a padding, wherein the padding support has two side bars connected to a plurality of strip-shaped ribs, and wherein the side spars are more flexible in the lordosis area, for example by rejuvenation, than in the upper and lower areas. In each case a pivot bearing and a sliding bearing can be attached as a connecting element for the back frame with the cushion support on the back of the side rails. The back frame may have two diagonal, intersecting struts, which the connects upper and lower connecting elements with each other, wherein the struts are connected to each other in the crossing point.
In einer weiteren Ausführungsform kann die Rückenlehne zusätzlich eine Nackenstütze aufweisen, wobei sie im Schulterbereich und dem Bereich der Nackenstütze eine, einer Schulter und Nacken angepasste, s-Form aufweisen kann. Die Bewegung der Nackenstütze verhält sich beim Einsitzten und Zurücklehnen gleich wie der Schulterbereich und garantiert so, dass auch der Kopf immer optimal gestützt ist.In a further embodiment, the backrest can additionally have a neck support, wherein in the shoulder region and the region of the neck support it can have an "S" shape adapted to a shoulder and neck. The movement of the neck support behaves the same way as the shoulders when seated and reclined, thus guaranteeing that the head is always optimally supported.
