Description

Höhenverstellbare Rückenlehne für Sitze, insbesondere Fahrzeugsitze sowie Fahrzeugsitz mit einer solchen Rückenlehne Height-adjustable backrest for seats, in particular vehicle seats and vehicle seat with such a backrest
Die Erfindung bezieht sich auf eine höhenverstellbare Rückenlehne für Sitze, insbesondere Fahrzeugsitze, insbesondere für Sitze von Straßenfahrzeugen und dabei speziell für PKW-Sitze.The invention relates to a height-adjustable backrest for seats, in particular vehicle seats, in particular for seats of road vehicles, and in particular for car seats.
Aufgabe der Erfindung ist es, eine höhenverstellbare Rückenlehne aufzuzeigen, bei der in jeder Verstellposition eine an den normalen, anatomischen Verlauf des Rückens bzw. der Wirbelsäule optimal angepaßte Form der Rückenlehne erhalten bleibt.The object of the invention is to demonstrate a height-adjustable backrest in which a shape of the backrest which is optimally adapted to the normal, anatomical course of the back or the spine is retained in each adjustment position.
Zur Lösung dieser Aufgabe ist eine Rückenlehne entsprechend dem Patentanspruch 1 ausgebildet. Ein Fahrzeugsitz mit einer solchen Rückenlehne ist entsprechend dem Patentanspruch 8 ausgebildet.To solve this problem, a backrest is designed according to claim 1. A vehicle seat with such a backrest is designed according to claim 8.
Mit der erfindungsgemäßen Ausbildung läßt sich bei der Höhenverstellung der Rückenlehne die anatomisch richtige Form dieser Rückenlehne optimal einhalten. Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche. Die Erfindung wird im folgenden anhand der Figuren an einem Ausführungsbeispiel näher erläutert. Es zeigen:With the design according to the invention, the anatomically correct shape of this backrest can be optimally maintained when adjusting the height of the backrest. Developments of the invention are the subject of the dependent claims. The invention is explained in more detail below with reference to the figures using an exemplary embodiment. Show it:

Fahrzeugsitzes; Fig. 2 in vereinfachter Darstellung und in Draufsicht ein inneres Abstützelement derVehicle seat; Fig. 2 in a simplified representation and in plan view an inner support member of the
Rückenlehne der Figur 1 . Von dem in den Figuren allgemein mit 1 bezeichneten Fahrzeugsitz ist in der Figur 1 allgemein mit 2 die Rückenlehne und der die eigentliche Sitzfläche bildende Teil des Sitzes wiedergegeben.Backrest of Figure 1 Of the vehicle seat, generally designated 1 in the figures, the backrest and the part of the seat forming the actual seat surface are shown generally in FIG.
Die Rückenlehne 2 ist entsprechend dem Doppelpfeil A in der Höhe um einen bestimmten Betrag verstellbar. Um hierbei eine anatomisch optimal angepaßte Form für die Rückenlehne beizubehalten, besteht diese aus einer vertikalen oder entsprechend der Neigung der Rückenlehne 2 geneigten Säule 4, die in der Mitte der Rückenlehne 2 vorgesehen ist und an der mehrere Abstützelemente 5 in Säulenlängsrichtung aufeinander folgend vorgesehen sind. Jedes Abstützelement 5 liegt mit seiner Längserstreckung quer oder radial zur Längserstreckung der Säule 4, ist in seiner Mitte an der Säule 4 gehalten und axial an dieser Säule verschiebbar geführt. Hierfür ist an der Rückseite jedes Abstützelementes 5 ein hülsenartiges Führungselement 6 vorgesehen, welches auf die Säule 4 aufgesteckt ist. Die Abstützelemente 5 sind an dieser mit dem Führungselement 6 versehenen Rückseite konvex und an der Vorderseite, die auch der Vorderseite der Rückenlehne 2 zugewandt ist, konkav gekrümmt. Sämtliche Abstützelemente 5 besitzen bei der dargestellten Ausführungsform weiterhin die selbe Länge.The backrest 2 is adjustable according to the double arrow A in height by a certain amount. In order to maintain an anatomically optimally adapted shape for the backrest, this consists of a vertical or inclined column 4 corresponding to the inclination of the backrest 2, which is provided in the middle of the backrest 2 and on which several support elements 5 are provided in succession in the longitudinal direction of the column. Each support element 5 lies with its longitudinal extension transverse or radial to the longitudinal extension of the column 4, is held in the middle on the column 4 and guided axially displaceably on this column. For this purpose, a sleeve-like guide element 6 is provided on the back of each support element 5, which is attached to the column 4. The support elements 5 are convex on this rear side provided with the guide element 6 and curved concavely on the front side, which also faces the front side of the backrest 2. All support elements 5 in the illustrated embodiment continue to have the same length.
Der anatomischen Form der Wirbelsäule eines menschlichen Körpers entsprechend besitzen aber die Abstützelemente 5 jeweils einen unterschiedlichen Abstand von der Säule 4, was durch unterschiedliche Länge eines Steges 7 erreicht wird, der das jeweilige Führungselement 6 mit der Mitte des Abstützelementes 5 an seiner konvexen Seite verbindet.According to the anatomical shape of the spine of a human body, however, the support elements 5 each have a different distance from the column 4, which is achieved by different lengths of a web 7, which connects the respective guide element 6 to the center of the support element 5 on its convex side.
An ihren freien Enden sind die Abstützelemente 5 teleskopartig ineinandergreifend aneinander geführt, d.h. die Abstützelemente 5 besitzen dort bei der dargestellten Ausführungsform rohrförmige Abschnitte 8, die jeweils oberhalb und unterhalb des jeweiligen Abstützelementes 5 einen unterschiedlichen Querschnitt aufweisen, d.h. beispielsweise oberhalb des jeweiligen Abstützelementes 5 einen Innenquerschnitt der gleich dem Außenquerschnitt unterhalb des jeweiligen Abschnittelementes ist, so daß die rohrförmigen Abschnitte 8 sämtlicher Abstützelementer 5 teleskopartig ineinandergreifen können.At their free ends, the support elements 5 are guided in a telescoping manner, that is to say the support elements 5 have tubular sections 8 in the embodiment shown, each above and below the respective support element 5 have a different cross-section, ie for example above the respective support element 5 an inner cross-section which is equal to the outer cross-section below the respective section element, so that the tubular sections 8 of all support elements 5 can interlock telescopically.
Auf der Säule 4 sind zwischen den Abstützelementen 5 federnde Abstandhalter 9 vorgesehen. Ein entsprechender Abstandhalter 9 ist auch zwischen dem untersten Abstützelement 5 und einem Gegenlager an der Säule 4 vorgesehen. Durch die Abstandhalter 9 sind die Abstützelemente 5 in eine obere Stellung vorgespannt, die der obersten Verstellstellung der verstellbaren Rückenlehne 2 entspricht. Durch ein Antriebselement, beispielsweise durch einen auf das Führungselement 6 des obersten Abstützelementes 5 wirkenden Seilzug, der in der Figur 1 mit der Linie 10 angedeutet ist und von einem in der Säule 4 untergebrachten Stellglied, beispielsweise einem elektrischen Antrieb betätigt wird, können das oberste Abstützelement 5 und mit diesem auch die darunterliegenden Abstützelemente 5 jeweils gegen die Wirkung der Abstandhalter 9 nach unten bewegt werden, um so die Rückenlehne 2 zunehmend in ihre untere Verstellposition zu bewegen.Resilient spacers 9 are provided on the column 4 between the support elements 5. A corresponding spacer 9 is also provided between the lowermost support element 5 and a counter bearing on the column 4. The spacers 9 prestress the supporting elements 5 into an upper position, which corresponds to the uppermost adjustment position of the adjustable backrest 2. The uppermost support element can be actuated by a drive element, for example by a cable pull acting on the guide element 6 of the uppermost support element 5, which is indicated in FIG. 1 by the line 10 and is actuated by an actuator accommodated in the column 4, for example an electric drive 5 and with this also the underlying support elements 5 are each moved downwards against the action of the spacers 9, so as to increasingly move the backrest 2 into its lower adjustment position.
Durch unterschiedliche elastische Ausbildung der Abstandhalter 9 wird erreicht, daß sich bei der Verstellung der Rückenlehne 2 der Abstand zwischen den Abstützelementen 5 unterschiedlich ändern und somit für das von sämtlichen Abstützelementen 5 gebildete innere Abstützeinheit der Rückenlehne 2 eine Form beibehalten wird, die dem anatomischen Verlauf des Rückens bzw. der Wirbelsäule bei Personen unterschiedlicher Größe optimal entspricht.Through different elastic design of the spacers 9 it is achieved that when the backrest 2 is adjusted, the distance between the support elements 5 changes differently and thus a shape is maintained for the inner support unit of the backrest 2 formed by all the support elements 5, which corresponds to the anatomical course of the Back or spine in people of different sizes.
Auf die von den Abstützelementen 5 gebildete Abstützeinheit ist die übliche Polsterung einer Fahrzeugrückenlehne aufgebracht, allerdings so, daß durch diese die Höhenverstellung der Rückenlehne 2 nicht beeinträchtigt ist. Die äußere Bespannung der Rückenlehne ist vorzugsweise von einem elastischen oder dehnbaren Gewebe gebildet.The usual upholstery of a vehicle backrest is applied to the support unit 5 formed by the support elements 5, but in such a way that the Height adjustment of the backrest 2 is not affected. The outer covering of the backrest is preferably formed by an elastic or stretchable fabric.
Das oberste Abstützelement 5 bildet selbstverständlich mit einer entsprechenden Polsterung die Oberseite der Rückenlehne. Mit dem obersten Abstützelement 5 ist auch die Kopfstütze 1 1 verbunden, so daß diese bei der Höhenverstellung der Rückenlehne 2 automatisch mit verstellt wird. Die Kopfstütze 1 1 bildet weiterhin auch einen Raum 12, der das obere Ende der Säule 4 beim Verstellen der Rückenlehne 2 aufnehmen kann.The uppermost support element 5 naturally forms the top of the backrest with appropriate padding. With the uppermost support element 5, the headrest 1 1 is connected, so that this is automatically adjusted with the height adjustment of the backrest 2. The headrest 1 1 also forms a space 12 which can accommodate the upper end of the column 4 when adjusting the backrest 2.
Die Ausbildung ist weiterhin bevorzugt so getroffen, daß die einzelnen Abstützelemente 5 gegen die Wirkung einer Rückstell kraft, die beispielsweise durch die Polsterung, die Sitzbespannung, durch die Elastizität der ineinander greifenden Rohrabschnitt 8 oder aber durch zusätzliche Federelemente, beispielsweise durch die Rohrabschnitte 8 hindurchgeführte Federn gebildet ist, aus ihrer Ausgangslage, in der die Abstützelemente 5 mit ihrer konkaven Seite zur Vorderseite des Sitzes hin gerichtet sind, um die Achse der Säule 4 soweit verdreht werden können, daß sich eine im Fahrzeugsitz 1 sitzende Personen unter einem leichten Verwinden der Rückenlehne 2 bequem zur Seite oder nach rückwärts wenden kann.The training is further preferably made so that the individual support elements 5 against the action of a restoring force, for example, by the upholstery, the seat covering, by the elasticity of the interlocking pipe section 8 or by additional spring elements, for example springs passed through the pipe sections 8 is formed from its starting position, in which the support elements 5 are directed with their concave side toward the front of the seat, about the axis of the column 4 can be rotated so far that a person sitting in the vehicle seat 1 with a slight twisting of the backrest 2 can easily turn to the side or backwards.
Die Säule 4 sowie auch die Abstützelemente 5 bestehen selbstverständlich aus einem geeigneten, hochfesten Material, beispielsweise aus Stahl oder aus faserverstärktem Kunststoff. Die Abstandhalter sind beispielsweise Körper aus einem gummielastischen Material, beispielsweise aus elastischen Kunststoff. Als Abstandhalter eignen sich aber auch Federn aus Stahl. Das unterste Abstützelement 5 ist bei der dargestellten Ausführungsform fest, zumindest aber derart mit der Säule 4 verbunden, daß sich dieses Abstützelement axial an der Säule 4 nicht verschieben kann. Zum Kippen der Rückenlehne 1 sowie auch zum Verstellen der Neigung dieser Rückenlehne ist die Säule 4 an ihrem unteren Ende in geeigneter Weise an einem Rahmen des Fahrzeugsitzes 1 schwenkbar vorgesehen, und zwar unter Beibehaltung der bei Fahrzeugsitzen üblichen Funktionen. Auch wenn in der Fig. 1 nur vier Abstützelemente gezeigt sind, kann die Rückenlehne eine höhere Anzahl solcher Elemente aufweisen.The column 4 as well as the support elements 5 are of course made of a suitable, high-strength material, for example steel or fiber-reinforced plastic. The spacers are, for example, bodies made of a rubber-elastic material, for example made of elastic plastic. Steel springs are also suitable as spacers. The lowest support element 5 is fixed in the embodiment shown, but at least connected to the column 4 in such a way that this support element cannot move axially on the column 4. For tilting the backrest 1 and also for adjusting the inclination of this backrest, the column 4 is suitably pivotably provided at its lower end on a frame of the vehicle seat 1, while maintaining the functions customary in vehicle seats. Even if only four support elements are shown in FIG. 1, the backrest can have a higher number of such elements.
Die Erfindung wurde voranstehend an einem Ausführungsbeispiel beschrieben. Es versteht sich, daß zahlreiche Änderungen sowie Abwandlungen möglich sind, ohne daß dadurch der der Erfindung zugrundeliegende Erfindungsgedanke verlassen wird. The invention has been described above using an exemplary embodiment. It goes without saying that numerous changes and modifications are possible without thereby departing from the inventive idea on which the invention is based.
