Abstract

The seat has backrest shaped parts (1) for supporting a support surface. Multiple parts (2) receive the respective shaped parts and extend in a same direction as the shaped parts. An arrangement rotates the shaped and receiving parts in opposite direction for changing an inclination of the support surface with the alignment of the respective parts being maintained.

Description

Die Erfindung betrifft eine Sitzschale, Sitz oder Liege, deren Stützfläche von gekrümmt verlaufenden Formteilen gehalten wird und dadurch gekennzeichnet sind dass diese unterteilt sind und an den Teilungsübergangsstellen Dreh- und/oder Schwenklager aufweisen, so, dass das Ende eines Formteils die Richtung des nächsten Formteils bestimmt und durch gegensinniges Verdrehen aneinandergereihter Formteile große Auslenkungen der Stützfläche bei kleinem Schwenkbereich der Formteile oder eine Verlängerung des Wirkbereichs der Formteile, durch ein Dreh/Schwenklager das ein Fluchten eines folgenden Elements gewährleistet. Ein Sitz oder eine Liege zeichnet sich des weiteren auch dadurch aus, dass die Stützfläche ein in einer Richtung biegsames Gebilde einer Bespannung mit Seitenteilen ist, die in Richtung der Bespannung steif, in Längsrichtung jedoch biegsam sind und die Bespannung auf Distanzhalter übertragen.The invention relates to a seat shell, seat or couch, whose support surface is held by curved moldings and are characterized in that they are divided and at the division transition points rotary and / or pivot bearings, so that the end of a molding the direction of the next molding determined and by opposing twisting juxtaposed moldings large deflections of the support surface with a small swivel range of the moldings or an extension of the effective range of the moldings, by a rotary / pivot bearing ensures an alignment of a following element. A seat or a couch is also characterized by the fact that the support surface is a flexible in one direction structure of a fabric with side panels that are stiff in the direction of the fabric, but flexible in the longitudinal direction and transmit the fabric to spacers.

Aufgabe der Erfindung ist es eine rückenkrümmungsgerechte Sitz- beziehungsweise Liegehaltung zu gewährleisten, die der natürlichen entspannten Körperhaltung entspricht, ohne jeweils eine Eigenbewegungskorrektur vornehmen zu müssen.The object of the invention is to ensure a rückenkrümmungsgerechte sitting or lying position, which corresponds to the natural relaxed posture, without having to make a proper motion correction.

Die Aufgabe der Erfindung wurde dadurch gelöst, dass die Lehnenkontur in aufrechter Sitzhaltung der veränderbaren Lehnenneigung angepasst wird. Bei einer Sitzschale, deren Stützfläche von gekrümmt verlaufenden verdrehbaren Formteilen gehalten und festgelegt wird, sind die Formteile unterteilt und an den Teilungsübergangsstellen Dreh- und Schwenklager oder Schwenklager angeordnet. Die Lehnenneigung, die Lehnenkontur und die Sitzneigung sind derart gekoppelt, dass das Ende eines Formteils die Richtung des nächsten Formteiles bestimmt und durch gegensinniges und synchronisiertes Verdrehen aneinandergereihter Formteile durch ein Dreh/Schwenklager ein Fluchten eines folgenden Elements gewährleistet.The object of the invention was achieved in that the backrest contour is adjusted in upright posture of the variable backrest angle. In a seat shell, the support surface is held and fixed by curved extending rotatable moldings, the mold parts are divided and arranged at the graduation transition points rotary and pivot bearings or pivot bearings. The backrest inclination, the backrest contour and the seat inclination are coupled in such a way that the end of a molded part determines the direction of the next molded part and ensures an alignment of a following element by opposing and synchronized rotation of juxtaposed molded parts by a rotary / pivot bearing.

Desweiteren wird, um ein Nachvomerutschen bei stark zurückgelehnter Haltung zu verhindern,die Sitzneigung erhöht, durch schwächer ausgebildete Lodosenstützung. Die Konstruktionsanpassung im oberen Rückenbereich im Sinne einer annähernd senkrechten Kopfpositionshaltung wirkt entspannend auf den Schulter- und Nackenbereich.Furthermore, in order to prevent Nachvuterutschen in strongly reclined posture, the seat tilt increased, by less trained Lodos support. The design adjustment in the upper back area in the sense of an approximately vertical head position posture has a relaxing effect on the shoulder and neck area.

Die Stützfläche ist ein in einer Richtung biegsames Gebilde einer Bespannung mit Seitenteilen, die in Richtung der Bespannung steif, in Längsrichtung jedoch biegsam sind und die die Bespannung auf Distanzhalter übertragen.The support surface is a flexible in one direction structure of a fabric with side panels that are stiff in the direction of the fabric, but flexible in the longitudinal direction and the covering transferred to spacers.

Figur 5, zeigt die Konturveränderungen in der progressiven Abfolge 1 bis 4, wie sie gemäß der erfindungsgemäßen konstruktiven Merkmale, verselbständigend beim Zurücklehnen ablaufen.Figure 5 shows the contour changes in the progressive sequence 1 to 4, as they expire in accordance with the constructive features of the invention, independently when leaning back.

Die Erfindung wird anhand der folgenden Figuren 1 bis 7 beschrieben:The invention will be described with reference to the following figures 1 to 7:

Fig. 1 und 2 zeigen die Anfangs und Endkonturen der Formteile 1 aus der Seiten und Frontansicht eines Stuhl in der Aufrechtposition. Die Stützfläche 14 wird in eine Form gezwungen, die durch das Verdrehen der Formteile 1 verändert wird. Das Kopfteil 9 ist an deren oberen Ende mittels dem Verbindungsstück 10 derart befestigt, dass es immer zu den Enden der Formteile 1 fluchtet.Fig. 1 and 2 show the beginning and end contours of the moldings 1 from the sides and front view of a chair in the upright position. The support surface 14 is forced into a shape which is changed by the rotation of the mold parts 1. The head part 9 is fixed at its upper end by means of the connecting piece 10 in such a way that it is always aligned with the ends of the molded parts 1.

Die Formteile 1 sind in der Aufnahme 2 derart gelagert, dass nur durch ein gegensinniges Verdrehen von 1 und 2 eine Veränderung der Lehnenneigung geschehen kann, wie in Fig.1 und Fig. 3 gezeigt und wodurch ebenfalls die Lehnenkontur verändert wird.The moldings 1 are mounted in the receptacle 2 in such a way that a change in the backrest inclination can only take place by an opposing rotation of 1 and 2, as shown in FIGS. 1 and 3, and whereby the backrest contour is also changed.

Fig. 3 und 4 zeigen den gleichen Stuhl in der Seiten und Frontansicht in zurückgelehnter Position.Figs. 3 and 4 show the same chair in the side and front view in a reclined position.

Die Aufnahmen 2 sind im Gehäuse 3 drehbar gelagert und erlauben das Kippen auf dem Sockel 6 wie in Figur 3:The receptacles 2 are rotatably mounted in the housing 3 and allow the tilting on the base 6 as in Figure 3:

Die Verdrehung von 2 bewirkt über die Hebel 4 und die Schubstangen 5 das Kippen von Gehäuse 3 auf dem Sockel 6, wodurch die Aufnahmen 2 zugleich gegensinnig synchronisiert werden. Somit sind die Lehnenneigung, die Lehnenkontur und die Sitzneigung gekoppelt.The rotation of 2 causes via the lever 4 and the push rods 5, the tilting of housing 3 on the base 6, whereby the recordings 2 are synchronized in opposite directions at the same time. Thus, the Lehnenneigung, the backrest contour and the seat tilt are coupled.

Fig. 6 zeigt den Scherenmechanismus 11 mit der Gasdruckfeder 12 und Zugstangen 13. Hier wird gedeutet, wie die blockierbare Gasdruckfeder beim Zurücklehnen zusammenfährt. Sie bringt die Gegenkraft zum Körpergewicht und Arretierbarkeit in jeder Lage.Fig. 6 shows the scissor mechanism 11 with the gas spring 12 and tie rods 13. Here is interpreted how the lockable gas spring collapses when leaning back. It brings the counterforce to body weight and lockability in every situation.

Fig. 7 zeigt die Stützfläche 14 bestehend vorzugsweise aus den biegsamen Seitenteilen 17, die mit einer Bespannung 16 vernäht sind und die Spannkraft der Distanzhalter 15 gleichmäßig auf die Bespannung übertragen. Die Distanzhalter können steif sein, wenn die Bespannung dauerelastisch ist. Die Distanzhalter 15 können flach an der Bespannung anliegen, wenn sie nach hinten schwenken können, während sich die Bespannung dem Körper anpasst.Fig. 7 shows the support surface 14 consisting preferably of the flexible side parts 17, which are sewn to a fabric 16 and transmit the clamping force of the spacers 15 evenly on the fabric. The spacers can be stiff if the covering is permanently elastic. The spacers 15 can lie flat against the fabric when they can pivot backwards while the fabric adjusts to the body.

Die Seitenteile 17 sind rückseitig mit einem elastischen Gewebe aufgedoppelt und vernäht, sodass eine Tasche entsteht, in der sich die Formteile 1 bewegen können und die Stützfläche 14 gut anliegt.The side parts 17 are doubled back with an elastic fabric and sewn, so that a bag is formed in which the mold parts 1 can move and the support surface 14 fits well.

Fig. 8 zeigt die Möglichkeit der Einstellbarkeit der Bespannungshärte, die zum Beispiel im Bereich der Lordosenstütze sinnvoll ist, indem durch Drehen des Handrades 18 im Lager 19 die Weite des Distanzhalters 15 variiert werden kann. Das Handrad und der Distanzhalter sind mit einem Gewinde versehen, das die Längenveränderung bewirkt.Fig. 8 shows the possibility of adjustability of the stringing hardness, which makes sense, for example, in the lumbar support, by turning the handwheel 18 in the bearing 19, the width of the spacer 15 can be varied. The hand wheel and the spacer are provided with a thread that causes the length change.

Die Erfindung ist ein Beitrag im Bereich der Gesundheitsvorsorge und funktioniert umweltfreundlich ohne äußere Energiezufuhr.
