Les nervures (2, 3) sont pourvues latéralement à leurs extrémités supérieures libres d'avancées (7, 8) qui s'étendent vers l'arrière à peu près parallèlement à la surface inférieure (1), tandis que les nervures inclinées vers l'arrière (4, 5, 6) sont également pourvues latéralement à leurs extrémités supérieures libres d'avancées (9, 10, 11) qui s'étendent de même à peu près parallèlement à la plaque inférieure (1), mais vers l'avant, de telle manière que les avancées (7, 8, 9, 10, 11) recouvrent en partie les intervalles (12) et forment, avec les extrémités supérieures libres des avancées (2, 3, 4, 5, 6), une assise (13).The seat object of the invention has several ribs (2, 3, 4, 5, 6) projecting relative to the lower surface (1) of the seat, approximately parallel to each other and perpendicular to the direction in which it is sits with the front ribs (2, 3) tilted forward, while the other ribs (4, 5, 6) tilt back. The ribs (2, 3) are provided laterally at their free upper ends with projections (7, 8) which extend rearwardly approximately parallel to the lower surface (1), while the ribs inclined towards the 'rear (4, 5, 6) are also laterally provided at their free upper ends with projections (9, 10, 11) which similarly extend approximately parallel to the lower plate (1), but towards the front, so that the projections (7, 8, 9, 10, 11) partly overlap the gaps (12) and form, with the free upper ends of the projections (2, 3, 4, 5, 6), a seat (13).

Description

BESCHREIBUNG DESCRIPTION
Sitzauflage Die Erfindung betrifft eine Sitzauflage, einstückig geformt aus einem dauerelastischen Werkstoff, mit einem Bodenteil und einer Vorderseite sowie einer gegenüberliegenden Rückseite.Seat cover The invention relates to a seat cover, formed in one piece from a permanently elastic material, with a base part and a front side and an opposite rear side.
Diese Sitzauflage kann ein separates Teil sein, das auf einen Sit aufgelegt wird. Diese Sitzauflage kann aber auch in einen Sitz integriert sein bzw. werden und stellt dann die obere Lage dieses Sitzes dar und ist direkt unter der Sitzfläche angeordnet. Natürl kann diese Sitzauflage mit einem Bezug etc. überzogen sein.This seat cover can be a separate part that is placed on a sit. However, this seat cover can also be integrated into a seat and then represents the upper layer of this seat and is arranged directly under the seat. Of course, this seat cover can be covered with a cover, etc.
Derartige bekannte Sitzauflagen dienen im allgemeinen dazu, eine weichere Sitzmöglichkeit zu schaffen. Dies führt zwangsläufig daz daß eine Ventilation, hervorgerufen durch Be- und Entlastungs- Vorgänge, nicht bzw. nur in ungenügendem Maße stattfindet, was da ein Schwitzen mit den üblichen, höchst unerwünschten Erscheinunge mit sich bringt. Man könnte diesem Übelstand zwar dadurch abhelfe daß man solche Sitzauflagen dicker gestaltet, was aber wiederum d Nachteil aufweist, unhandlich zu sein bzw. eine ungewollte Sitzhö zu ergeben, woraus eine mangelnde Stabilität resultiert. Außerdem tritt hier die Tendenz des Herunterrutschens, vor allem nach vorn verstärkt in Erscheinung.Such known seat covers generally serve to create a softer seat. This inevitably leads to the fact that ventilation, caused by loading and unloading processes, does not take place or only takes place to an inadequate extent, which results in sweating with the usual, highly undesirable phenomena. This could be remedied by making such seat cushions thicker, which in turn has the disadvantage of being unwieldy or resulting in an unwanted seat height, which results in a lack of stability. In addition, there is a tendency to slide down, especially towards the front.
Der Erfindung liegt die Aufgabe zugrunde, eine Sitzauflage der erwähnten Gattung zu schaffen, die bei Belastungsschwankungen ein ausreichende Belüftung (Ventilation) ergibt und somit ein schwitz¬ freies Sitzen ermöglicht sowie gleichzeitig einem Herunterrutschen nach vorne entgegenwirkt.The invention has for its object to provide a seat cover of the type mentioned that a load fluctuations sufficient ventilation (ventilation) results and thus enables a sweat-free sitting and at the same time counteracts slipping down to the front.
Diese Aufgabe wird durch eine Sitzauflage gemäß der Lehre des Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen sind in den Unteransprüchen 2 bis 5 beschrieben.This object is achieved by a seat cover according to the teaching of claim 1. Advantageous embodiments are described in subclaims 2 to 5.
Nachstehend ist eine bevorzugte Ausführungsform der erfindungs¬ gemäßen Sitzauflage unter Bezug auf die schematischen Zeichnungen näher beschrieben; es zeigen:A preferred embodiment of the seat cover according to the invention is described in more detail below with reference to the schematic drawings; show it:
Fig. 1 eine perspektivische Ansicht der erfindungs¬ gemäßen Sitzauflage; Fig. 2 eine Seitenansicht derselben.1 is a perspective view of the seat cover according to the invention; Fig. 2 is a side view of the same.
Die in der Fig. 1 gezeigte erfindungsgemäße Sitzauflage ist ein¬ stückig aus einem dauerelastischen Werkstoff mit einem spezifischen Gewicht von 40 bis 100 kg/m3 geformt. Die Sitzauflage ist im unbelasteten Zustand dargestellt und weist ein Bodenteil 1 mit in etwa rechteckiger Grundfläche auf. Insbesondere aus der Fig. 2 ist ersichtlich, daß aus dem Bodenteil fünf quer zur Sitzrichtung ver¬ laufende Stege 2,3,4,5,6 nach oben herausragen. Die Stege 2,3 sind dabei im vorderen Bereich, der Steg 4 im mittleren Bereich und die Stege 5,6 im hinteren Bereich angeordnet. Diese Stege sind in etwa parallel zueinander angeordnet und lassen zwischen sich Steg¬ zwischenräume 12 frei. Die linke Seite der in den Figuren gezeigten Sitzauflage stellt die Vorderseite dar, während die rechte Seite die Rückseite darstellt. Mit dem Ausdruck "Sitzrichtung" wird somit die Richtung von der Rückseite in Richtung auf die Vorderseite bezeichnet. Die Stege 2,3 sind zur Vorderseite hin geneigt und besitzen seitlich an ihren freien Enden Vorsprünge 7,8, die sich in etwa horizontal zur Vorderseite hin erstrecken. Die Stege 4,5,6 sind zur Rückseite hin geneigt und besitzen ebenfalls seitlich an ihren freien Enden Vorsprünge 9,10,11, die sich in etwa horizontal erstrecken, jedoch in Richtung auf die Rückseite. Diese Vorsprünge überdecken teilweise die Stegzwischenräume 12 und bilden zusammen mit den oberen freien Enden eine Sitzfläche 13, wie dies aus der Fig. 1 zu ersehen ist. Der Steg 2 ist seitlich an seinem oberen freien Ende mit einem lappenartigen Fortsatz 14 ausgestattet, der bis zum Bodenteil 1 umgeschlagen ist, so daß er mit der Unterseite des Bodenteils 1 bündig abschließt. An der Innenseite dieses lappenartigen Fortsat 14 sind mehrere quer verlaufende Stützstege 15 vorgesehen, die si in den durch das Umschlagen gebildeten Hohlraum erstrecken.The seat cover according to the invention shown in FIG. 1 is formed in one piece from a permanently elastic material with a specific weight of 40 to 100 kg / m 3 . The seat cover is shown in the unloaded state and has a base part 1 with an approximately rectangular base. It can be seen in particular from FIG. 2 that five webs 2, 3, 4, 5, 6 extending transversely to the seat direction protrude upward from the base part. The webs 2, 3 are arranged in the front area, the web 4 in the middle area and the webs 5, 6 in the rear area. These webs are arranged approximately parallel to one another and leave web spaces 12 between them. The left side of the seat pad shown in the figures represents the front, while the right side represents the back. The expression “seat direction” thus denotes the direction from the rear towards the front. The webs 2, 3 are inclined towards the front and have laterally at their free ends projections 7, 8 which extend approximately horizontally towards the front. The webs 4, 5, 6 are inclined towards the rear and also have projections 9, 10, 11 on their free ends, which extend approximately horizontally, but in the direction of the rear. These projections partially cover the web spaces 12 and, together with the upper free ends, form a seat surface 13, as can be seen from FIG. 1. The web 2 is laterally equipped at its upper free end with a tab-like extension 14 which is turned over to the bottom part 1 so that it is flush with the underside of the bottom part 1. On the inside of this tab-like fortress 14, a plurality of transverse support webs 15 are provided which extend into the cavity formed by the folding.
Beim Benutzen der Sitzauflage verformen sich die Stege 2,3,4,5,6 jeweils in Neigungsrichtung, wobei die Stege 2,3 eine nach vorne wirkende Kraft und die Stege 4,5,6 eine nach rückwärts (zur Rücke lehne hin) gerichtete Kraft hervorrufen. Daraus ergibt sich eine Kraft-Resultierende, die nach hinten gerichtet ist und sich einem Herunterrutschen des Benutzers nach vorne widersetzt. Außerdem erfolgt gleichzeitig durch das einander entgegengesetzt gerichtet Kräftepaar eine gewisse Spannung des auf der Sitzfläche 13 ruhend Kleidungsstücks des Benutzers, was eine Faltenbildung verhindert.When using the seat cushion, the webs 2, 3, 4, 5, 6 deform in each case in the direction of inclination, the webs 2, 3 a forward-acting force and the webs 4, 5, 6 a rearward (towards the backrest) directed Evoke strength. This results in a force resultant which is directed backwards and opposes the user sliding downwards. In addition, due to the oppositely directed pair of forces, there is a certain tension in the garment of the user resting on the seat 13, which prevents creasing.
Die Vorsprünge 7,8,9,10,11, welche die Stegzwischenräume 12 teil¬ weise überdecken, ergeben zusammen mit den oberen freien Enden de Stege eine angenehme Federung und erlauben bei Lastwechsel eine maximale Ventilation, d.h. eine durch Be- und Entlasten erzeugte Belüftung der Sitzauflage und damit auch insbesondere der Sitzflä 13, wodurch ein Feuchtwerden der aufliegenden Kleidung, hervor¬ gerufen durch ein Schwitzen des Benutzers, weitgehend verhindert wird.The projections 7, 8, 9, 10, 11, which partially cover the web spaces 12, together with the upper free ends of the webs result in a pleasant suspension and allow maximum ventilation when the load changes, i.e. ventilation of the seat cover, and thus in particular of the seat surface 13, caused by loading and unloading, which largely prevents the clothes lying on them from becoming damp, caused by the user sweating.
Es sei noch erwähnt, daß die Sitzfläche 13 leicht nach hinten abfällt. Mit anderen Worten, die vertikale Höhe der Stege 3,4,5,6 nimmt zum rückwärtigen Ende leicht ab. Dies ergibt eine bessere u bequemere Sitzstellung, als sie durch bekannte Sitzauflagen mit einer weitaus stärkeren Rückwärtsschrägung zu erzielen ist. Durch das Umschlagen des der Vorderseite zugewandten lappenartigen Fort satzes 14 einerseits und des querverlaufenden Stützstegs 15 ander seits sind ergσnomische Teile gebildet, welche ihrerseits gleich¬ falls zu einer besseren und praktisch ermüdungsfreien Sitzpositio beitragen.It should also be mentioned that the seat 13 slopes slightly backwards. In other words, the vertical height of the webs 3, 4, 5, 6 decreases slightly towards the rear end. This results in a better and more comfortable sitting position than can be achieved with known seat cushions with a much greater backward slope. By turning over the flap-like extension 14 facing the front and the transverse support web 15 on the other, ergonomic parts are formed, which in turn also contribute to a better and practically fatigue-free seating position.
Um auch den Steg 6 voll wirksam werden zu lassen, ist ein an der Rückseite der Sitzauflage parallel zum Steg 6 verlaufenderIn order to also make the web 6 fully effective, there is a running on the back of the seat cover parallel to the web 6
Distanzwulst 16 angebracht, der verhindert, daß der Steg 6 an ein Rückenlehne anstößt und dadurch an Wirksamkeit verliert, weil er sich nicht in dem gewünschten Maße nach hinten verformen kann. Zur Unterstützung der Federungseigenschaften und der Ventilation sind die Stege 2,3,4,5,6 auf ihrer die Sitzfläche 13 bildenden Oberfläche mit einer nutartigen Vertiefung 17 versehen, wobei diese Vertie¬ fungen 17 parallel zueinander verlaufen.Spacer 16 attached, which prevents the web 6 to a Hits the backrest and loses its effectiveness because it cannot deform backwards to the desired extent. To support the suspension properties and ventilation, the webs 2, 3, 4, 5, 6 are provided with a groove-like depression 17 on their surface forming the seat surface 13, these depressions 17 running parallel to one another.
Der vordere Bereich mit zur Vorderseite geneigten Stegen 2,3 macht im übrigen vorzugsweise 1/5 bis zu 2/5 des gesamten Sitzbereiches aus.The front area with webs 2, 3 inclined towards the front preferably makes up 1/5 to 2/5 of the entire seating area.
Durch die vorstehend dargelegten Eigenschaften der erfindungsgemäße Sitzauflage ist es ohne weiteres verständlich, daß durch Bewegungen des darauf sitzenden Benutzers (Belastungswechsel) und/oder durch ein etwas holperiges Fahren, wenn die Sitzauflage auf einem Fahr¬ zeugsitz liegt, eine Bindegewebsmassage bzw. Lymphdrainage erfolgt, die wohl allgemein, insbesondere aber von Rollstuhlfahrern, sehr begrüßt wird.Due to the properties of the seat cover according to the invention described above, it is readily understandable that a connective tissue massage or lymphatic drainage takes place through movements of the user sitting on it (change in load) and / or through somewhat bumpy driving when the seat cover lies on a vehicle seat. which is generally welcomed, especially by wheelchair users.
Die Anzahl der Stege ist selbstverständlich variabel und nicht auf die im Ausführungsbeispiel angegebene Anzahl beschränkt.The number of webs is of course variable and is not limited to the number specified in the exemplary embodiment.
In der Praxis ist es zweckmäßig, die Sitzauflage in eine Hülle zu stecken, die nicht zu eng sein darf, um die erwünschten Verformunge zuzulassen. In practice, it is advisable to put the seat cover in a cover that must not be too tight to allow the desired deformation.
