Description
Die Erfindung bezieht sich auf einen Stuhl mit abgefederter Rückenlehne.The invention relates to a chair with a cushioned backrest.
Es sind bereits solche Stühle bekannt, bei welchen jedoch der Nachteil vorhanden ist; daß die Rückenlehne bei weich eingestellter Federung zu leicht nach hinten ausweichen kann und dadurch ohne weiteres auf den maximalen Ausschlag zurückgedrängt wird. Bei hart eingestellter Federung ist dagegen der Druck auf den Rücken zu groß, so daß die Federwirkung nur ungenügend ist.Such chairs are already known, but which have the disadvantage is available; that the backrest moves too easily when the suspension is set to a soft level can move backwards and thus easily pushed back to the maximum deflection will. If the suspension is set hard, on the other hand, the pressure on the back is too great, so that the spring action is insufficient.
Dieser Nachteil soll durch den Stuhl gemäß der Erfindung dadurch behoben werden, daß die Rückenlehne verschwenkbar an einem festen Stützteil gelagert ist und daß eine federnde Stütze an dem einen Ende mit der Rückenlehne und an dem anderen Ende mit dem Sitz gelenkig derart verbunden ist, daß sie dem Verschwenken der Rückenlehne einen mit zunehmendem Neigungswinkel größer werdenden Widerstand entgegensetzt. Dadurch wird eine sehr angenehm wirkende Abfederung der Rückenlehne erreicht.This disadvantage is intended to be remedied by the chair according to the invention be that the backrest is pivotably mounted on a fixed support part and that a resilient support on one end with the backrest and on the other End is hinged to the seat in such a way that it allows the pivoting of the backrest opposes a resistance that increases with increasing angle of inclination. This results in a very pleasant cushioning of the backrest.
Zweckmäßigerweise ist die federnde Stütze durch eine abgebogene Blattfeder gebildet, welche sich bei der Verschwenkung der Rückenlehne federnd ausbiegt.The resilient support is expediently provided by a bent leaf spring formed, which bends resiliently when the backrest is pivoted.
Die Anlenksbelle der federadden Stütze an der Rückenlehne kann zwecks Regulierung der Nachgiebigkeit der Lehne auf- und abwärts verstellbar sein.The pivot bracket of the spring-loaded support on the backrest can be used for the purpose of Regulation of the flexibility of the backrest can be adjusted up and down.
Ferner kann die Anlenkstelle der federnden Stütze am Sitz zwecks Regulierung des Neigungswinkels der Rückenlehne in der Ruhestellung vor-und rückwärts verstellbar sein.Furthermore, the articulation point of the resilient support on the seat for the purpose of regulation the angle of inclination of the backrest can be adjusted forwards and backwards in the rest position be.
Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in einem senkrechten Teilschnitt durch einen Stuhl dargestellt.The drawing shows an embodiment of the subject matter of the invention shown in a vertical partial section through a chair.
Die Rückenlehne i ist um die Drehachse 2 verschwenkbar an dem festen Stützteil 3 gelagert, der auf der Unterseite des Sitzes 4 befestigt ist. Eine durch eine abgebogene Blattfeder 5 gebildete federnde Stütze ist einerends mittels einer Drehachse 6 mit der Rückenlehne i und anderends mittels einer Drehachse 7 mit dem Sitz 4 gelenkig verbunden. Bei einer Verschwenkung der Rückenlehne i um die Drehachse 2 setzt die Blattfeder 5 der Verschwenkbewegung zuerst nur einen geringen Widerstand entgegen, da, wie aus den eingetragenen Kreisbögen ersichtlich ist, die Blattfeder 5 zuerst nur wenig ausgebogen werden muß. Bei größerem Neigungswinkel der Rückenlehne i nimmt der Widerstand rasch zu, indem sich die Blattfeder 5 immer stärker ausbiegen muß. Dadurch wird der Neigungswinkel auch ohne Anschlag begrenzt, und die Federung ist sehr angenehm.The backrest i is pivotable about the axis of rotation 2 on the fixed Support part 3 mounted, which is attached to the underside of the seat 4. One through a bent leaf spring 5 formed resilient support is at one end by means of a Axis of rotation 6 with the backrest i and at the other end by means of an axis of rotation 7 with the Seat 4 articulated. When the backrest i is pivoted about the axis of rotation 2, the leaf spring 5 initially sets only a slight resistance to the pivoting movement contrary, because, as can be seen from the entered circular arcs, the leaf spring 5 only needs to be bent out a little at first. With a larger angle of inclination of the backrest The resistance increases rapidly as the leaf spring 5 bends more and more got to. This limits the angle of inclination even without a stop, and so does the suspension is very pleasant.
Die Anlenkstelle 6 der Blattfeder 5 an der Rückenlehne i kann auf- und abwärts verstellbar sein, wodurch die Nachgiebigkeit der Lehne reguliert werden kann.The articulation point 6 of the leaf spring 5 on the backrest i can be and adjustable downwards, thereby regulating the flexibility of the backrest can.
Ferner kann auch die Anlenkstelle 7 der Blattfeder 5 am Sitz 4 vor- und rückwärts verstellbar sein, wodurch der Neigungswinkel der Rückenlehne in deren Ruhestellung reguliert werden kann.Furthermore, the articulation point 7 of the leaf spring 5 on the seat 4 can also be and be adjustable backwards, whereby the angle of inclination of the backrest in their Rest position can be regulated.
