Abstract
Description
Die Erfindung betrifft eine anatomisch geformte Sitzschale. Sitzschalen, die der Anatomie des menschlichen Gesäßes angepaßt sind, verbessern die Sitzstabilität und reduzieren die Spitzendrücke, die meist unter den Sitzbeinhöckern des Gessäßes auftreten. Ein Beispiel dafür ist der Treckersitz, eine aus Stahlblech tiefgezogene und gelochte Sitzschale. Eine fast vollkommene Nivellierung des Sitzdruckes über die ganze Sitzfläche, die in schwierigen Fällen im Rollstuhlbereich benötigt wird, bieten individuell angepaßte Sitzschalen, z. B. nach dem Shape System der Fa. Otto Bock oder nach dem Silhouette-Verfahren der Fa. Invacare. In PS DE 4405595 und PS DE 19617912 ist ein weiteres derartiges Verfahren beschrieben worden. Für die allgemeine Anwendung sind solche individuell angepaßten Sitzschalen allerdings ungeeignet.The invention relates to an anatomically shaped seat shell. Seat shells that the Anatomy of the human buttocks are adapted to improve seat stability and reduce the peak pressures, mostly under the buttocks of the gessäß occur. An example of this is the tractor seat, a deep-drawn one made of sheet steel and perforated seat shell. An almost perfect leveling of the seat pressure over the entire seat, which is needed in difficult cases in the wheelchair area will offer individually adapted seat shells, e.g. B. according to the shape system from Otto Bock or using the silhouette method from Invacare. In PS DE 4405595 and PS DE 19617912 another such method is described been. For general use, such individually adapted seat shells are however unsuitable.
Die Erfindung hat sich die Aufgabe gestellt, eine anatomisch geformte Sitzschale für die allgemeine Anwendung zu schaffen. Sie geht davon aus, daß ein Hängegurt, der bei Klappstühlen und Rollstühlen üblich ist, sich zwar etwas an die Gesäßform anpassen kann; ihrer eindimensionalen Krümmung wegen ist diese Anpassung aber unzureichend und sie erzeugt einen unphysiologischen Druck auf die Trochanter des Sitzenden. Vor allem aber liegen die tiefsten Stellen des Hängegurts in der Medianebene (die den menschlicher Körper in eine linke und rechte Hälfte teilt). Demgegenüber liegen die tiefsten Stellen einer anatomisch geformten Sitzschale unter den beiden Sitzbeinhöckern und unter den beiden Oberschenkeln. Hier setzt die Erfindung dadurch an, daß die Sitzfläche in quer zur Medianebene liegende Sitzbänder aufgeteilt wird, deren etwas unterschiedliche Länge eine dreidimensionale Sitzfläche ermöglicht. Ferner ist eine Medianstütze vorgesehen, deren Oberkante die Sitzbänder in der Medianebene anhebt, so daß die tiefsten Stellen der durch die Sitzbänder definierten Sitzschale aus der Medianebene nach außen unter die Sitzbeinhöcker und unter die Oberschenkel verlagert werden. Besonders bemerkenswert ist hierbei, daß sich diese tiefsten Stellen selbsttätig unter dem Gewicht des Sitzenden an der richtigen Stelle einstellen, bei breiten sowohl wie bei schmalen Gesäßen. Dieser Umstand ermöglicht es, die Oberkante der Medianstütze und die Länge der Sitzbänder z.B. nach dem 95. Perzentil des weiblichen Gesäßes auszulegen.The object of the invention is an anatomically shaped seat shell to create for general use. She assumes that a hanging belt which is common with folding chairs and wheelchairs, adapts somewhat to the shape of the buttocks can adjust; This adaptation is due to its one-dimensional curvature but insufficient and it creates an unphysiological pressure on the trochanter of the seated. Above all, however, are the lowest parts of the hanging belt at the median level (which divides the human body into left and right Half divides). In contrast, the deepest parts of an anatomically shaped Seat shell under the two buttocks and under the two thighs. This is where the invention comes in that the seat surface is transverse to the median plane lying seat bands is divided, the slightly different length of one three-dimensional seat enables. A median support is also provided, the upper edge of which raises the seat bands in the median plane so that the deepest Readjust the seat shell defined by the seat bands from the median level outside under the buttocks and under the thighs. Especially It is noteworthy here that these lowest points are located automatically adjust the weight of the seated person in the right place, both wide like narrow buttocks. This fact allows the top of the Median support and the length of the seat belts e.g. after the 95th percentile of the female To lay out the buttocks.

In Fig. 1 ist der prinzipielle Aufbau der Sitzschale dargestellt. Sie besteht aus dem linken Seitenprofil (1), dem rechten Seitenprofil (2), der Medianstütze (3) und den Sitzbändern (6), von denen nur die vorderen vier in Fig.1 dargestellt sind. Weitere Sitzbänder (6) schließen sich an, um die ganze Sitzfläche abzudecken. Für den Fall, daß diese Sitzschale auch noch faltbar sein soll, um sie z.B. im Rollstuhlbereich einzusetzen, sind vordere Tragbänder (4) und hintere Tragbänder (5) vorgesehen, die die Medianstütze (3) an der unteren Längskante abstützen. Die Montage dieser faltbaren Sitzschale erfolgt durch Anschrauben der Seitenprofile (1, 2) auf den Sitzrohren des Faltrollstuhls. In ähnlicher Weise erfolgt die Montage der Sitzschale bei Auto oder Flugzeugsitzen. Bei Bürostühlen, die einen zentralen Fuß bzw. Verstellmechanismus haben, sind die Seitenprofile (1, 2) und die Medianstütze (3) starr mit diesem verbunden; die Tragbänder (4, 5) entfallen. Die Tragbänder (4, 5) als auch die Sitzbänder (6) sind durch Schrauben, Nieten, Klemmen, Kleben, oder Schweißen an den Seitenprofilen (1, 2) und an der Medianstütze (3) befestigt. In Fig. 1 the basic structure of the seat shell is shown. It consists of the left side profile (1), the right side profile (2), the median support (3) and the Seat bands (6), of which only the front four are shown in Fig.1. Further Seat bands (6) connect to cover the entire seat. For the Case that this seat shell should also be foldable to e.g. in the wheelchair area front straps (4) and rear straps (5) are provided, which support the median support (3) on the lower longitudinal edge. The assembly This foldable seat shell is made by screwing on the side profiles (1, 2) on the seat tubes of the folding wheelchair. The assembly of the Seat shell for car or airplane seats. For office chairs that have a central foot or adjustment mechanism are the side profiles (1, 2) and the median support (3) rigidly connected to it; the carrying tapes (4, 5) are omitted. The straps (4, 5) and the seat belts (6) are by screws, rivets, clamps, gluing, or welding on the side profiles (1, 2) and on the median support (3) attached.
Bei Großserienfertigung können die Sitzbänder (6), die Seitenprofile (1, 2) und die Medianstütze (3), eventuell auch die Verbindungselemente zwischen den Seitenprofilen (1,2) und der Medianstütze (3) einstückig im Spritzgießverfahren hergestellt werden. Hierdurch können alle eben genannten Befestigungen entfallen. Die Seitenprofile (1, 2) können auch zu einem Rahmen erweitert werden, an dem die Medianstütze (3) hängt.In large series production, the seat belts (6), the side profiles (1, 2) and the Median support (3), possibly also the connecting elements between the side profiles (1,2) and the median support (3) made in one piece by injection molding become. As a result, all the fastenings just mentioned can be omitted. The Side profiles (1, 2) can also be expanded to a frame on which the Median support (3) hangs.
Wegen der guten Anpassung der erfindungsgemäßen Sitzschale an die jeweilige Anatomie des Gesäßes kann ein (nicht dargestelltes) auf den Sitzbändern (6) liegendes Schaumstoffkissen flacher als üblich sein und somit die Sitzstabilität des Benutzers verbessern. Der Abstand der Sitzbänder (6) voneinander, die offenporige Struktur des Schaumstoffkissens und dessen geringe Dicke sorgen für eine hohe Luft- und Wasserdampfdurchlässigkeit und somit für ein vorzügliches Mikroklima des Sitzes. Diese Durchlässigkeit ist bei allen formgeschäumten Autositzen ein Schwachpunkt, weil die beim Herstellungsprozeß entstehende Oberfläche einem Luft- und Wasserdampftransport hinderlich ist.Because of the good adaptation of the seat shell according to the invention to the respective Anatomy of the buttocks can be one (not shown) lying on the seat belts (6) Foam pillow be flatter than usual and thus the stability of the seat Improve user. The distance between the seat belts (6) from each other, the open-pore Structure of the foam cushion and its small thickness ensure a high air and water vapor permeability and thus for an excellent microclimate of the seat. This permeability is with all molded car seats a weak point because the surface created during the manufacturing process Air and water vapor transport is a hindrance.
Die weitere Ausgestaltung der Erfindung beschäftigt sich mit dem Spezialfall Sitzschale für Rollstühle und der hierfür erforderlichen Anpassung an die verschiedenen Rollstuhl-Breitenmaße. Fig.2 zeigt die in zwei Hälften (10, 11) mit identischem Umriß aufgeteilte Medianstütze, zwischen denen die Tragbänder (4, 5) und die Sitzbänder (6) längenmäßig justiert und mittels der Schrauben (13) festgeklemmt werden. Fig.3 zeigt einen Ausschnitt aus der Draufsicht der Sitzschale. Hier ist zu sehen, wie die Sitzbänder (6) mit Teilstrichen und Zahlen (38, 40) bedruckt sind, die die Sitzbreite des Rollstuhls betreffen und die Breiten-Justage der Sitzschale erleichtern. Die Tragbänder (4, 5) sind in gleicher Weise bedruckt. Die Bedruckung der Sitzbänder (6) untereinander ist nicht völlig identisch: Da die Sitzbänder (6) zur optimalen Anpassung an die Gesäßform einen etwas unterschiedlichen Durchhang haben, ist z.B. der Abstand der Teilstriche des unter den Sitzbeinhöckern liegenden Sitzbandes (6) etwas größer. Ein derart auf die notwendige Breite eingestellte Sitzschale wird mit einem aufgelegten Schaumstoffkissen eine im Vergleich zum Hängegurt sehr gute Gleichmäßigkeit der Druckverteilung aufweisen. The further embodiment of the invention deals with the special case of the seat shell for wheelchairs and the necessary adaptation to the different Wheelchair width dimensions. Fig.2 shows the two halves (10, 11) with identical Outline divided median support, between which the support bands (4, 5) and the Seat straps (6) adjusted in length and clamped using the screws (13) become. 3 shows a detail from the top view of the seat shell. Here is too see how the seat bands (6) are printed with tick marks and numbers (38, 40), that affect the seat width of the wheelchair and the width adjustment of the seat shell facilitate. The carrying tapes (4, 5) are printed in the same way. The printing the seat bands (6) are not completely identical to each other: since the seat bands (6) for optimal adaptation to the shape of the buttocks a little different sag have is e.g. the distance of the divisions of the under the ischial bumps lying seat belt (6) slightly larger. One set to the necessary width in this way Seat shell is one in comparison with an applied foam cushion have very good pressure distribution uniformity to the hanging belt.
Wenn im individuellen Fall aber noch eine Druckspitze empfunden oder gemessen wird, kann das an dieser Stelle liegende Sitzband (6) nach Lockern der benachbarten Schrauben (13) etwas verlängert werden, was zur sofortigen Reduzierung der Druckspitze führt. Die erfindungsgemäße Sitzschale kann aber nicht nur in ihrer Breite verändert werden sondern auch in ihrer Lange. Hierzu werden die beiden Hälften (10, 11) der Medianstütze und die beiden Seitenprofile (1, 2) an den vorderen Enden um 2 oder 4 Sitzbänder durch Sägen oder mit der Blechschere verkürzt. Bei Anwendung dieser Option sind die vorderen Tragbänder (4) um vier Bandteilungen nach hinten versetzt.If, in an individual case, a pressure peak is felt or measured the seat belt (6) located at this point can be loosened after loosening the neighboring one Screws (13) are lengthened slightly, resulting in an immediate reduction the pressure peak leads. The seat shell according to the invention can not only in their width can be changed but also in their length. To do this, the two Halves (10, 11) of the median support and the two side profiles (1, 2) on the front ends by 2 or 4 seat bands by sawing or with tin snips shortened. When using this option, the front straps (4) are at four Band divisions offset to the rear.
Fig.4 zeigt eine spezielle Befestigung der Tragbänder (4, 5) und der Sitzbänder (6) an den Seitenprofilen (1, 2). Kennzeichnend hierfür sind unter 45 Grad eingestanzte Schlitze (14) in den Seitenprofilen (1, 2), durch die ein Band (4, 5, 6) eingefädelt und nach zweimaligem 45-Grad-Falten wieder herausgefädelt wird.4 shows a special fastening of the carrying straps (4, 5) and the seat straps (6) on the side profiles (1, 2). Characteristic of this are stamped under 45 degrees Slots (14) in the side profiles (1, 2) through which a band (4, 5, 6) is threaded and after two 45-degree folds is threaded out again.
Fig.5 zeigt eine rohrförmige Variante als Seitenprofil (20). Hierbei sind die Tragbänder (4, bzw. 5) und die Sitzbänder (6) auf das rohrförmige Seitenprofil (20) aufgewickelt und z.B. mit Blindnieten (21) befestigt. Mehrere auf dem Umfang liegende Durchgangslöcher (nicht dargestellt) erlauben dann eine Schraubbefestigung z.B auf den Sitzrohren des Rollstuhls und eine Breiteneinstellung der Sitzschale, je nachdem welche Durchgangslöcher benutzt werden.5 shows a tubular variant as a side profile (20). Here are the straps (4 or 5) and the seat belts (6) on the tubular side profile (20) wound up and e.g. fixed with blind rivets (21). Several on the perimeter Through holes (not shown) then allow screw fastening e.g. on the seat tubes of the wheelchair and a width adjustment of the seat shell, depending on which through holes are used.
Fig.6 zeigt schließlich eine Seitenprofil-Variante (30), die auf Rollen (31) gelagert ist, deren Achsen (32) an Lagerböcken (33) stecken, die auf die Sitzrohre (34) eines Rollstuhls geschraubt sind. Die Schräglage der Anordnung ergibt sich als Resultirende der Zugspannungen in den Tragbändern (4, 5) und in den Sitzbändern (6). Durch diese Anordnung kann der erfindungsgemäße Sitz längs der Sitzrohre (34) des Rollstuhls verschoben werden und somit das dem Fachmann bekannte 〈Dynamische Sitzen im Rollstuhl〉 (z. B. OS DE 19814067) ermöglichen. Die dafür erforderlichen manuellen oder servomotorischen Betätigungselemente sind bekannt und brauchen hier nicht erörtert zu werden. 6 finally shows a side profile variant (30) which is mounted on rollers (31) is, the axes (32) on the bearing blocks (33), which on the seat tubes (34) Wheelchair are screwed. The inclination of the arrangement results as the result the tensile stresses in the support straps (4, 5) and in the seat straps (6). With this arrangement, the seat according to the invention can be along the seat tubes (34) of the wheelchair are shifted and thus that known to the expert 〈Enable dynamic sitting in a wheelchair〉 (e.g. OS DE 19814067). The one for that required manual or servomotor actuators are known and need not be discussed here.
Als Halbzeug für die Tragbänder (5, 6) und die Sitzbänder (6) haben sich handelsübliche Verpackungsbänder aus gerecktem und geprägtem Polypropylen bewährt, die eine hohe Reißkraft besitzen. Sie sind aber so biegsam, daß die erfindungsgemäße, aus den Sitzbändern (6) gebildete Sitzschale sich der jeweiligen Gesäßanatomie anpaßt und im Spezialfall des Rollstuhls mühelos gefaltet werden kann.Semi-finished products for the carrying tapes (5, 6) and the seat tapes (6) are commercially available Packaging tapes made from stretched and embossed polypropylene, which have a high tear strength. But they are so flexible that the inventive seat shell (6) formed from the seat shell of the respective seat anatomy adapts and can be folded effortlessly in the special case of the wheelchair can.
