Description
Hohenverstelleinrichtung für KraftfahrzeugsitzeHeight adjustment device for motor vehicle seats
Die vorliegende Erfindung bezieht sich auf eine Hohenverstelleinrichtung für Kraftfahrzeugsitze mit an jeder Sitzlängsseite vorne und hinten angeordneten, auf im Sitzuntergestell drehbar gelagerten Querwellen angeordneten Kurvenscheiben, die den Sitzrahmen tragen und wobei die Querwellen mit radialen Hebelarmen verbunden sind, an deren freien Enden eine ver-3änger- und verkürzbare Längswelle angreift.The present invention relates to a height adjustment device for motor vehicle seats with front and rear arranged on each longitudinal side of the seat, arranged on transverse shafts rotatably mounted in the seat frame Cam disks that carry the seat frame and the cross shafts are connected with radial lever arms, at the free ends of which an extended and shortenable longitudinal shaft engages.
Aus der deutschen Patentschrift 1 091 882 ist bereits eine Hohenverstelleinrichtung der eingangs genannten Art bekannt. Bei dieser bekannten Hohenverstelleinrichtung ist die verlänger- und verkürzbare Längswelle durch eine Gewindewelle gebildet, die mit einem mit einem Innengewinde versehenen, sie umgebenden Rohr zusammenwirkt. Die Gewindewelle wird hierbei über einen Elektromotor in die jeweils gewünschte Drehrichtung gedreht und der Sitz somit angehoben oder abgesenkt.The German patent specification 1 091 882 already discloses a height adjustment device known of the type mentioned. In this known height adjustment device the extendable and shortenable longitudinal shaft is formed by a threaded shaft which is provided with an internal thread, it surrounding pipe cooperates. The threaded shaft is rotated in the desired direction of rotation by an electric motor, and thus the seat raised or lowered.
Diese bekannte Hohenverstelleinrichtung weist den Nachteil auf, dass sie durch den Elektromotor, das erforderliche Untersetzungsgetriebe und die elektrischen Steuereinrichtungen in der Herstellung verhältnismässig teuer und in der Funktion störanfällig ist.This known height adjustment device has the disadvantage that it relatively expensive to manufacture due to the electric motor, the required reduction gear and the electrical control devices and is prone to failure in its function.

In Fig. 1 ist ein Kraftfahrzeugsitz 1 mit einem Sitzrahmen 2 νβι-sehen, der auf einem in bekannter Weise horizontal verschiebbaren Sitzuntergestell 3 höhenverstellbar angeordnet ist. Die Höhenverstelleinrichtung besteht hierbei aus im Sitzuntergestell drehbar gelagerten Querwellen 4 und 5» die mit Kurvenscheiben 6 und 7 verbunden sind, die den Sitzrahmen 2 über käfigartige Teile 8 und 9 tragen und halten. Die Querwellen 4 und 5 sind hierbei mit radialen Hebelarmen 10 und 11 verbunden, die an ihren freien Enden Gewindemuttern 12 und 13 schwenkbar gelagert tragen.In Fig. 1 is a motor vehicle seat 1 with a seat frame 2 νβι-see, the on a seat frame 3 that is horizontally displaceable in a known manner Is arranged adjustable in height. The height adjustment device consists of transverse shafts 4 and 5, which are rotatably mounted in the seat frame, with cams 6 and 7 are connected, which carry and hold the seat frame 2 via cage-like parts 8 and 9. The transverse waves 4 and 5 are here with radial lever arms 10 and 11 connected, the threaded nuts at their free ends 12 and 13 pivoted to carry.
Eine Längswelle 14 ist an ihren beiden Enden 15 und 16 als Gewindebolzen ausgebildet und wird in den Gewindemuttern 12 und 13 aufgenommen. Die Längswelle 14 ist mit einer umschaltbaren Ratsche 17 versehen, die einen Betätigungsteil 18 und einen Umschaltteil 19 aufweist.A longitudinal shaft 14 is at both ends 15 and 16 as a threaded bolt and is received in the threaded nuts 12 and 13. the Longitudinal shaft 14 is provided with a switchable ratchet 17 which has an actuation part 18 and a switchover part 19.
Der Betätigungsteil l8 ist hierbei vorzugsweise mit einem um die Achse der Längswelle 14 schwenkbaren Betätigungshebel 20 versehen uni der Umschaltteil 19 weist ein konzentrisch zur Längswelle angeordnetes drehbares Umschalthandrad 21 auf.The actuating part l8 is here preferably with a around the axis of the Longitudinal shaft 14 is provided with pivotable actuating lever 20 and the switchover part 19 has a rotatable switchover handwheel arranged concentrically to the longitudinal shaft 21 on.
Die Kurvenscheiben 6 und 7 bzw die radialen Hebelarme 10 und 11 sind hierbei vorzugsweise so ausgelegt, dass der Sitz 1 vorn und hinten unterschiedlich und zwar in einem bestimmten Verhältnis von etwa 1 : 2 bis 1 : 3 angehoben oder abgesenkt werden.The cams 6 and 7 or the radial lever arms 10 and 11 are here preferably designed in such a way that the seat 1 is raised differently at the front and rear, namely in a certain ratio of approximately 1: 2 to 1: 3 or lowered.
In den Fig. 2 bis 4 sind die gleichen Bezugszeichen verwendet, eine eingehendere Beschreibung dieser Figuren ist somit nicht mehr erforderlich.The same reference numerals are used in FIGS. 2 to 4, one more detailed Description of these figures is therefore no longer necessary.
Wird der Betätigungshebel 20 zwischen seinen beiden Endstellungen hin und her bewegt, so wird je nach der vorgewählten Stellung des Umschalthandrades 21 die Ratsche 17 Drehmoment nur in der einen Richtung übertragen und eineIf the operating lever 20 between its two end positions and moved forward, so depending on the preselected position of the Umschalthandrades 21, the ratchet 17 torque is transmitted only in one direction and one

Rückkehrbewegung des Betätigungshebels 20 in der anderen Richtung im Freilauf ermöglichen, so dass ζ. B. beim Nachobenziehen des Betätigungshebels 20 ein Drehmoment auf die Längswelle 14 übertragen und der Sitz 1 angehoben wird, , während bei in seiner anderen Stellung vorgewählten Umschalthandrand 21 ein Nadiuntendrücken des Betätigungshebels 20 Drehmoment auf die Längswelle l4 überträgt und den Sitz 1 absenkt.Return movement of the operating lever 20 in the other direction in freewheeling enable so that ζ. B. when pulling up the operating lever 20 a Torque is transmitted to the propeller shaft 14 and the seat 1 is raised, while with the switching hand edge 21 preselected in its other position a Nadiunterpresses the actuating lever 20 torque on the propeller shaft l4 transfers and the seat 1 lowers.
Die erfindungsgemässe Anwendung einer umschaltbaren Ratsche 17 erbringt den Vorteil, dass die Betätigungseinrichtung der Höhenverstelleinrichtung unmittelbar neben dem Sitz angeordnet werden kann, wodurch die Einstellung der Sitzhöhe während der Fahrt ohne Veränderung der Sitzhaltung möglich ist, wobei durch die Ratschenwirkung trotz begrenztem Bewegungsraum für die Betätigungseinrichtung nur geringe Betätigungskräfte erforderlich sind.The inventive use of a switchable ratchet 17 provides the Advantage that the actuating device of the height adjustment device directly can be arranged next to the seat, whereby the seat height can be adjusted while driving without changing the sitting position, whereby due to the ratchet effect despite the limited space of movement for the actuating device only small operating forces are required.
Durch die unterschiedliche Anhebung des Sitzes vorn und hinten in einem Verhältnis von 1 : 2 bis 1 : 3 wird eine maximale Höhenverstellung ermöglicht, ohne dass hierdurch die Khiefreiheit zu stark beeinträchtigt wird.Due to the different elevation of the seat front and rear in a ratio from 1: 2 to 1: 3 a maximum height adjustment is possible, without this affecting the freedom of freedom too much.
