Abstract

The invention concerns a chair which can be dismantled and re-assembled and which is designed to adapt automatically, in accordance with human-engineering principles, to the position of the body of the occupant. During a transformation (Fig. 1), two plane surfaces (1, 2) can be moved, by support elements (4u) and frame components (4o), into a convex (1k, 2k) and at the same time transversally reinforcing (Fig. 2) yet longitudinally elastic position of use in which they have unsupported and freely flexing ends (1s, 2r) and loosely abutting (4c) ends.

Description

Der Erfindung liegt die Aufgabe zugrunde, ein solches Sitzmöbel mit automatischer Körperanpassung für dynamisches Sitzen nach ergonomischen Erkenntnissen zu schaffen.The invention is based on the object such seating with automatic body adjustment for dynamic sitting according to ergonomic To create insights.

Das wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruchs 1 abgegebenen Merkmale erreicht.This is according to the invention by the characteristic Part of claim 1 submitted Characteristics achieved.

Bei entsprechender Ausführung ist eine variantenreiche Nutzung des zusammenbau- und zerlegbaren Sitzmöbels möglich.With the appropriate design is a varied use of the assembly and demountable seating furniture possible.

Weitere Merkmale der Erfindung sind Gegenstand der abhängigen Ansprüche 2 bis 6.Other features of the invention are the subject of dependent claims 2 to 6.

Fig.1 Verdeutlicht die Transformation in eine konvexe und zugleich queraussteifende aber längselastische Gebrauchslage mit freitragenden und federnden Enden, indem der obere Teil eines Gestellteils 4o an Befestigungspunkten 4a and 4b sowohl die im Bereich 4c lose anschlagende Sitz- 1 und Rückenfläche 2 als auch ein unteres Tragelemente 4u hält. Die konvexen Flächen 1k und 2k stützen und entlasten die Wirbelsäule aber nicht nur im Becken-Lendenwirkbelbereich, sondern optimieren mit ihren freifedernden Enden 1s and 2r die Körperhaltung in jeder Sitzposition. So können der Oberkörper im Bereich seiner Brustkyphose nach hinten überdehnt (Stretchair-Effekt) und die Beine ohne Druckstellen im Kniekehlenbereich ausgestreckt werden.Fig.1 illustrates the transformation in a convex and at the same time cross-bracing but longitudinally elastic position with self-supporting and resilient ends by the top Part of a frame part 4o at attachment points 4a and 4b, both loosely striking in area 4c Seat 1 and back 2 as well a lower support member 4u holds. The convex surfaces 1k and 2k support and relieve the spine not only in the Pelvic lumbar area, but optimize with their spring-loaded ends 1s and 2r die Posture in every sitting position. So can the upper body in the area of his chest kyphosis stretched backwards (stretchair effect) and the legs without pressure points in the back of the knee be stretched out.

Fig.2 zeigt die queraussteifende Wirkung der hier alternative als Rahmen 7 ausgebildeten Sitz- und Rückenteile, die mit einem flächenbildenden Material 8 überzogen sind.Fig.2 shows the transverse stiffening effect of here alternatively trained as a frame 7 Seat and back parts with a surface-forming Material 8 are coated.

Fig.3 und Fig.4 zeigen zwei Varianten mit bis zum Boden reichenden Flächen, wobei im Punkt 4d ein zusätzliches Tragelement eingreift.Fig.3 and Fig.4 show two variants with to areas reaching to the floor, whereby in point 4d engages an additional support element.

Fig.5 zeigt, daß der obere Teil 4o auch nach unten gerichtet und mit einem üblichen Untergestell verbunden sein kann.Fig.5 shows that the upper part 4o also after directed below and with a usual base can be connected.
