Abstract

The seating surface is attached to a support (2) and has at least one two-part seat surface (3) which is adjustable transversely wrt. the seating position. The parts are pivotably linked and the rear part (3b) can be pivoted upwards and downwards with respect to the front part (3a) and has a cut-out. The individual seat surface parts can be replaced by means of a removable connecting element

Description

Die Erfindung betrifft eine verstellbare Sitzfläche für jede Art von Sitzvorrichtung, die auf einem Sitzunterbau befestigt ist und zumindest eine quer zur Sitzposition zweigeteilte Sitzfläche aufweist, welche schwenkbeweglich miteinander verbunden sind und wobei das hintere Sitzflächenteil mittels einem Verstellelement, bezogen auf das Sitzflächenniveau, senk- und anhebbar und weiterhin mit einer Aussparung versehen ist und wobei die einzelnen Sitzflächenteile austauschbar sind.The invention relates to an adjustable seat for any type of seat device, which is attached to a seat base and at least one transverse to the sitting position has two-part seat, which is pivotally connected to each other and the rear seat part is covered by means of an adjustment element to the seat level, can be lowered and raised and also with a recess is provided and the individual seat parts are interchangeable.

Für Personen mit einer ausgeprägten bzw. zur Hyperlordose tendierenden Lendenwirbelsäule ist es angenehm und gesundheitsförderlich, wenn eine Sitzfläche benutzt werden kann, die im Bereich des hinteren Beckens abgesenkt ist, wie es beispielsweise auf einem Sitzball oder während des Sitzens auf der Toilettenbrille erzielt wird, da in dieser Sitzstellung die gesamte Gliederkette Kreuzbein - Lumbosakralgelenk und die Lendenwirbel L5 bis L1 sich begradigt, ausstrecken kann und dadurch augenblicklich der Druck auf Bandscheiben und Nervenstränge reduziert wird, so daß schmerzhafte Zustände plötzlich nachlassen und langzeitlich gesehen, sich ein Hohlkreuz wieder zu einer normalen Lordose zurückentwickeln kann. Die Vorzüge des Tiefsitzens können unter anderen dadurch belegt werden, daß Personen, die lange stehen und insbesondere hochhackige Schuhe tragen, ein Hohlkreuz entwickeln, welches zu einseitigen Belastungen, Ermüdungs- und Schmerzzuständen führt, und mittels Tiefsitzen auf einfache Weise eine schnelle Regenerierung und Normalisierung der Lendenwirbelsäule erzielen.For people with a pronounced lumbar spine or a tendency towards hyperlordosis it is pleasant and healthy if you use a seat can be lowered in the area of the rear pelvis, such as it on a sitting ball or while sitting on toilet glasses, because in this sitting position the entire link chain sacral - lumbosacral joint and the lumbar vertebrae L5 to L1 straighten, stretch, and thereby instantly the pressure on intervertebral discs and nerve strands is reduced so that painful conditions suddenly subside and seen over a long period of time Hollow back can develop back to a normal lordosis. The benefits of deep sitting can be demonstrated, among other things, by the fact that people standing long and wearing high-heeled shoes in particular, a hollow back develop, which leads to one-sided stress, fatigue and pain leads, and a quick regeneration in a simple manner by deep sitting and achieve normalization of the lumbar spine.

Aufgabe der Erfindung ist es, eine Sitzfläche zu schaffen, die diese Sitzmöglichkeit bzw. diesen Zustand des Tiefsitzens auch auf jede andere Sitzvorrichtung überträgt.The object of the invention is to provide a seat that this seating or transfers this state of deep sitting to any other seat device.

Die Lösung dieser Aufgabe ist die Erfindung einer zweigeteilten Sitzfläche 1, deren hinteres bewegliches Sitzflächenteil 3b nicht nur bis zu 30° über Sitzflächenniveau angehoben (Fig. 1), sondern auch bis zu ca. 15° unter Sitzflächenniveau abgesenkt (Fig. 2) werden kann. Für diese Einstellmöglichkeiten ist ein besonderer dem erweiterten Platzbedarf angepaßter Höhenausgleich 6 am Sitzunterbau 2 zu schaffen. The solution to this problem is the invention of a two-part seat 1 , the rear movable seat part 3 b of which is not only raised up to 30 ° above the seat surface ( FIG. 1), but also lowered up to approx. 15 ° below the seat surface ( FIG. 2) can. For these adjustment options, a special height adjustment 6 on the substructure 2 is to be created which is adapted to the expanded space requirement.

Unabhängig von dem Niveau des beweglichen hinteren Sitzflächenteiles sollte in keinem Fall das Steißbein während des Sitzens einem Druck oder einer Stauchung insbesondere auch in einem schwingenden Fahrzeug ausgesetzt werden, so daß die Sitzfläche im Bereich der Steißbeinregion mit einer Aussparung (Fig. 3) versehen ist.Regardless of the level of the movable rear seat part, the tailbone should never be subjected to pressure or compression, especially in a swinging vehicle, while sitting, so that the seat in the area of the tailbone region is provided with a recess ( Fig. 3).

Die Austauschbarkeit insbesondere der hinteren verschwenkbaren Sitzfläche (Fig. 4) mittels einer entsprechenden Trennvorrichtung 7 betrifft beispielsweise den Austausch mit einem in sich zweigeteilten und individuell verstellbaren Sitzflächenteil, da dadurch in besonderen Fällen z. B. bei einer skoliösen Wirbelsäule die Sitzvorrichtung einfach umgerüstet werden kann, um nicht einen kompletten Sitzplatz zusätzlich anzuschaffen.The interchangeability, in particular of the rear swiveling seat surface ( FIG. 4) by means of a corresponding separating device 7 relates, for example, to the exchange with a seat part which is individually divided into two parts, since in special cases this means, for. B. with a scolous spine, the seat device can be easily converted so as not to purchase a complete seat.

Die Anmeldungen DE-Gm 18 54 149 und DE PS 12 56 840 enthalten verstellbare, keilartig nach hinten ansteigende Stützelemente, aber sehen keine Vorrichtung zur Absenkung derselben unter das Sitzflächenniveau vor, haben weiterhin keine Aussparung im Bereich der Steißbeinregion und keine Vorrichtung zum Austausch von einzelnen Sitzflächenteilen oder der gesamten Sitzfläche und verfügen über keine beidseitig leicht bedienbare Verstellvorrichtung.The applications DE-Gm 18 54 149 and DE PS 12 56 840 contain adjustable, Support elements rising wedge-like to the rear, but see no device for Lowering them below the seat level before, still have no recess in the area of the coccyx region and no device for the exchange of individual parts of the seat or the entire seat and have none Easy-to-use adjustment device on both sides.

Erfindungsgemäß ist eine einfache, leicht zugängliche und bedienerfreundliche Verstellbarkeit 5 des beweglichen Sitzflächenteiles beidseitig und/oder einseitig bedienbar vorgesehen, so daß die Option gefördert wird, kurzfristig die Beckenstellung zu verändern, um eine einseitige Druckbelastung und somit Ermüdungserscheinungen und Schmerzen vorzubeugen bzw. eine Entwicklung zu verhindern.According to the invention, a simple, easily accessible and user-friendly adjustability 5 of the movable seat part is provided on both sides and / or on one side, so that the option is promoted to change the pelvic position for a short time in order to prevent one-sided pressure load and thus fatigue and pain or development prevent.
