Description

Die Erfindung bezieht sich auf eine orthopädische Zusatzrückenlehne, insbesondere für Fahrzeugsitze, die mittels Gurten oder dgl. an der Rückenlehne des Sitzes befestigbar ist und aus einem die Wirbelsäule des Sitzbenutzers abstützenden Polster mit mindestens einer elastisch verformbaren, aufblasbaren Kammer besteht.The invention relates to an orthopedic additional backrest, in particular for vehicle seats, which can be fastened to the backrest of the seat by means of belts or the like and consists of a cushion which supports the spine of the seat user and has at least one elastically deformable, inflatable chamber.

Insbesondere beim Autofahren ist die Wirbelsäule des menschlichen Körpers extremen Belastungen ausgesetzt, da ständig Beschleunigungskräfte, Fliehkräfte, Schwingungen und Stöße abgefangen werden müssen. Die damit verbundene, dauernde Muskelanspannung kann mit der Zeit zu Ermüdungserscheinungen, Konzentrationsschwäche und Verkrampfung führen.Especially when driving a car, the spine of the human body is exposed to extreme loads, since acceleration forces, centrifugal forces, vibrations and shocks have to be absorbed constantly. The associated constant muscle tension can lead to fatigue, poor concentration and cramping over time.

Um ein ermüdungsfreies und gesundes Sitzen, insbesondere beim Autofahren, zu ermöglichen, ist aus dem DE-GM 77 27 880 ein Sitz bekannt, dessen Rückenlehne in dem der Abstützung der Wirbelsäule des Sitzbenutzers dienenden Bereich mindestens drei schlauchartige, elastisch verformbare Kammern aufweist, die sich übereinander in Richtung vom unteren zum oberen Rand der Rückenlehne erstrecken und unabhängig voneinander über Steuerorgane mit Druckmittel von einer Druckmittelquelle gefüllt werden können. Als Druckmittel wird dabei Luft verwendet und der Füllungsgrad der einzelnen Kammern ist frei wählbar, so daß das für jeden Sitzbenutzer optimale Längsprofil der Rückenlehne eingestellt werden kann. Ein derartiger Sitz ist in seiner Herstellung aufwendig und teuer. Das Nachrüsten eines Sitzes mit einer derartigen Längsprofileinstellung der Rückenlehne ist normalerweise nicht möglich.In order to enable fatigue-free and healthy sitting, especially when driving, a seat is known from DE-GM 77 27 880, the backrest of which has at least three hose-like, elastically deformable chambers in the area serving to support the spine of the seat user extend one above the other in the direction from the lower to the upper edge of the backrest and, independently of one another, can be filled with pressure medium from a pressure medium source via control members. Air is used as the pressure medium and the degree of filling of the individual chambers is freely selectable, so that the optimal longitudinal profile of the backrest can be set for each seat user. Such a seat is complex and expensive to manufacture. Retrofitting a seat with such a longitudinal profile adjustment of the backrest is normally not possible.

Aus dem DE-GM 81 15 166 ist ein aufblasbares und höhenverstellbares Gesundheitsrückenkissen bekannt, welches nachträglich an jedem Kraftfahrzeugsitz angebracht werden kann. Dieses Kissen ist mit einer Kammer versehen, die mehr oder minder stark durch den Mund mit Luft aufgeblasen wird. Dadurch ist die Einstellung eines optimalen Längsprofiles der Rückenlehne für den Sitzbenutzer äußerst schwierig und insbesondere während der Fahrt überhaupt nicht veränderbar. Darüber hinaus kann mit einem Kissen mit nur einer Kammer die Rückenlehne nicht in der gewünschten Weise an die Wirbelsäule, insbesondere im Lendenbereich, des Sitzbenutzers angepaßt werden.From DE-GM 81 15 166 an inflatable and height-adjustable health back cushion is known, which can be retrofitted to any motor vehicle seat. This pillow is provided with a chamber that is more or less inflated through the mouth with air. This makes it extremely difficult for the seat user to set an optimal longitudinal profile of the backrest and, in particular, it cannot be changed during the journey. In addition, the backrest cannot be adapted in the desired manner to the spine, in particular in the lumbar region, of the seat user with a cushion having only one chamber.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine orthopädische Zusatzrückenlehne, insbesondere für Fahrzeugsitze zu schaffen, die preiswert hergestellt und auch nachträglich an jedem Fahrzeugsitz angebracht werden kann und die eine optimale Abstützung der Wirbelsäule des Sitzbenutzers sicherstellt.The invention is therefore based on the object of creating an orthopedic additional backrest, in particular for vehicle seats, which can be produced inexpensively and can also be retrofitted to each vehicle seat and which ensures optimum support for the spine of the seat user.

Zur Lösung dieser Aufgabe wird gemäß der Erfindung vorgeschlagen, daß mindestens zwei übereinander angeordnete und quer zur Rückenlehne verlaufende Kammern vorgesehen sind und die Kammern über getrennte Leitungen mit mindestens einem Handblaseball mit Entlüftungsventil verbunden sind. Dadurch kann sich jeder Sitzbenutzer das für ihn optimale und bequeme Längsprofil der Rückenlehne einstellen und bei Bedarf, sogar während der Fahrt, verändern. Auch vorhandene Fahrzeugsitze können nachträglich mit dieser Rückenlehne ausgerüstet werden.To achieve this object, it is proposed according to the invention that at least two chambers arranged one above the other and extending transversely to the backrest are provided and the chambers are connected via separate lines to at least one hand-held ballball with vent valve. As a result, every seat user can adjust the optimal and comfortable longitudinal profile of the backrest and change it if necessary, even while driving. Existing vehicle seats can also be retrofitted with this backrest.

Weitere Merkmale der Erfindung sind in den Ansprüchen 2 - 5 offenbart.Further features of the invention are disclosed in claims 2-5.

Die Erfindung wird nachfolgend anhand in einer Zeichnung dargestellter Ausführungsbeispiele näher erläutert.The invention is explained in more detail below with reference to exemplary embodiments shown in a drawing.

Dabei zeigen

  • Fig. 1 einen Kraftfahrzeugsitz mit einer Zusatzrückenlehne nach der Erfindung,
  • Fig. 2 einen mit der Fig. 1 übereinstimmenden Kraftfahrzeugsitz mit einer weiteren Ausbildung der Zusatzrückenlehne.
Show
  • 1 shows a motor vehicle seat with an additional backrest according to the invention,
  • Fig. 2 with the Fig. 1 matching motor vehicle seat with a further design of the additional backrest.

In den Fign. 1 und 2 der Zeichnung ist jeweils ein Sitz 1 eines Kraftfahrzeuges dargestellt, dessen Rückenlehne 2 mit einer orthopädischen Zusatzrückenlehne 3 versehen ist. Diese Zusatzrückenlehne 3 erstreckt sich über den mittleren Bereich der Rückenlehne 2. Mittels zwei Gurten 4 ist die Zusatzrückenlehne 3 an der Rückenlehne 2 unverrückbar festgespannt.In Figs. 1 and 2 of the drawing, a seat 1 of a motor vehicle is shown, the backrest 2 of which is provided with an additional orthopedic backrest 3. This additional backrest 3 extends over the central region of the backrest 2. By means of two belts 4, the additional backrest 3 is fixed immovably on the backrest 2.

Die Zusatzrückenlehne 3 ist aus einem rechteckigen Polster gebildet, welches im Lendenbereich des Sitzbenutzers drei schlauchartige, übereinander angeordnete und quer zur Rückenlehne verlaufende Kammern 5 - 7 aufweist, die aus Gummi gefertigt und in die Zusatzrückenlehne 3 eingesetzt sind und die in diesem Beispiel einen unterschiedlichen Querschnitt bzw. eine unterschiedliche Breite besitzen. Diese unterschiedliche Breite gestattet eine besonders gute Anpassung der Zusatzrückenlehne 3 an die Wirbelsäule des Sitzbenutzers.The additional backrest 3 is formed from a rectangular cushion which, in the lumbar region of the seat user, has three tubular chambers 5 - 7 arranged one above the other and extending transversely to the backrest, which are made of rubber and inserted into the additional backrest 3 and which in this example have a different cross section or have a different width. This different width allows a particularly good adaptation of the additional backrest 3 to the spine of the seat user.

An die Kammer 5 ist eine Schlauchleitung 8 mit einem Absperrventil 9 angeschlossen, die über ein Abzweigstück 10 und eine weitere Schlauchleitung 11 zu einem an sich bekannten Handblaseball 12 mit integriertem Rückschlagventil und Entlüftungsventil 12a führt. Auch in die Kammer 6 mündet eine Schlauchleitung 13 mit einem Absperrventil 14, die ebenfalls über das Abzweigstück 10 und die Schlauchleitung 11 angeschlossen ist. Im Gegensatz zu den Kammern 5 und 6 weist die Kammer 7 keine besondere, an den Handblaseball 12 angeschlossene Leitung auf. Die Kammer 7 ist jedoch über nur angedeutete Strömungskanäle mit der Kammer 6 verbunden.A hose line 8 with a shut-off valve 9 is connected to the chamber 5, which leads via a branch piece 10 and a further hose line 11 to a hand-held ball ball 12 known per se with an integrated check valve and vent valve 12a. Even in the Chamber 6 opens a hose line 13 with a shut-off valve 14, which is also connected via the branch piece 10 and the hose line 11. In contrast to the chambers 5 and 6, the chamber 7 has no special line connected to the hand-held ball 12. The chamber 7 is, however, connected to the chamber 6 by means of only indicated flow channels.

Die Einstellung des Längsprofils der Rückenlehne 2 mit der Zusatzrückenlehne 3 erfolgt nun in der Weise, daß der Sitzbenutzer - sobald er seine Sitzstellung eingenommen hat - das Entlüftungsventil 12 absperrt und bei geöffneter Stellung der Absperrventile 9, 14 durch Betätigung des Handblaseballes 12 nacheinander oder gleichzeitig Luft in die Kammern 5 - 7 pumpt. Dieser Pumpvorgang für die Kammer 5 und/oder für die Kammern 6, 7 wird dann beendet, wenn sich eine ausreichende Luftmenge in den Kammern 5 - 7 befindet und damit das gewünschte Längsprofil der Rückenlehne 2 mit Zusatzrückenlehne 3 erreicht ist. Anschließend können die Absperrventile 9, 14 wieder geschlossen werden.The adjustment of the longitudinal profile of the backrest 2 with the additional backrest 3 is now carried out in such a way that the seat user - as soon as he has taken his seated position - shuts off the ventilation valve 12 and, when the shut-off valves 9, 14 are open, by actuating the hand-held ball 12 in succession or simultaneously air pumps into chambers 5 - 7. This pumping process for the chamber 5 and / or for the chambers 6, 7 is ended when there is a sufficient amount of air in the chambers 5-7 and the desired longitudinal profile of the backrest 2 with the additional backrest 3 is thus achieved. The shut-off valves 9, 14 can then be closed again.

Bei einer Veränderung der Sitzstellung kann entweder weitere Luft in die Kammern 5 - 7 gepumpt oder abgelassen werden. Die dadurch erreichbare Veränderung des Längsprofiles der Rückenlehne 2 mit Zusatzrückenlehne 3 kann auch während der Fahrt vorgenommen werden. Um die Absperrventile 9, 14, den Handblaseball 12 und das Entlüftungsventil 12a sicher betätigen zu können, ist es möglich, dieselben auf einer besonderen Konsole oder dgl. zu befestigen.If the seat position is changed, more air can either be pumped into the chambers 5 - 7 or released. The change in the longitudinal profile of the backrest 2 with the additional backrest 3 that can be achieved can also be carried out while driving. In order to be able to actuate the shut-off valves 9, 14, the hand-held ball 12 and the vent valve 12 a safely, it is possible to fix them on a special console or the like.

In Abänderung dieses Ausführungsbeispieles ist es möglich, auch die Kammer 7 über eine besondere Leitung mit einem Absperrventil und ein anders ausgebildetes Abzweigstück direkt über den Handblaseball 12 mit Luft zu füllen. Die beiden Absperrventile 9, 14 können darüberhinaus in das Abzweigstück 10 integriert sein, wodurch sich der Herstellungs- und Montageaufwand verringert. Ferner können auch zwei oder vier Kammern vorgesehen werden.In a modification of this exemplary embodiment, it is also possible to fill the chamber 7 with air via a special line with a shut-off valve and a differently designed branch piece directly via the hand-held ball 12. The two shut-off valves 9, 14 can also in the Branch piece 10 may be integrated, which reduces the manufacturing and assembly costs. Furthermore, two or four chambers can also be provided.

Bei dem Ausführungsbeispiel der Fig. 2 münden die Schlauchleitungen 8, 13 nicht in ein Abzweigstück 10 und von dort in eine gemeinsame Schlauchleitung 11 mit einem Handblaseball 12 mit integriertem Rückschlagventil und mit Entlüftungsventil 12a. Hier ist vielmehr jeder Schlauchleitung 8, 13 ein eigener Handblaseball 12 mit integriertem Rückschlagventil und mit Entlüftungsventil 12a zugeordnet. Weiterhin sind hier in das Polster der Zusatzrückenlehne 3 nur zwei schlauchartige Kammern 5, 6 eingesetzt.In the embodiment of FIG. 2, the hose lines 8, 13 do not open into a branch piece 10 and from there into a common hose line 11 with a hand-held ballball 12 with an integrated check valve and with a vent valve 12a. Rather, each hose line 8, 13 is assigned its own hand-held ballball 12 with an integrated check valve and with a vent valve 12a. Furthermore, only two tube-like chambers 5, 6 are inserted into the cushion of the additional backrest 3.
