An unlocking lever (13) hinges on the seat on an axis parallel to the rail, moving the pins in opposition to the springs by one end. At the other end it has a cam surface (20) adjusting the velocity ratio between it and an operating lever (18) acting against it. The operating lever likewise hinges in a bearing (24) parallel to the rail. The operating lever can be double-armed, with a boss (17) at one end acting against the unlocking lever, and a handle (25) at the other. USE/ADVANTAGE - Easy hand operation of vehicle seat adjustment, requiring virtually constant effort.

Description

Die Erfindung betrifft eine Verriegelung für eine Längsver­ stellung eines Sitzes, insbesondere eines Fahrzeugsitzes.The invention relates to a lock for a longitudinal ver position of a seat, in particular a vehicle seat.

Aus dem DE-GM 89 13 244 ist ein einstellbarer Fahrzeugsitz be­ kannt, deren Längsverstellung über eine gattungsgemäße Vorrich­ tung mit mehreren Rastbolzen verriegelbar ist. Die Rastbolzen sind dabei so angeordnet und gestaltet, daß in jeder beliebigen Sitzstellung mindestens ein Rastbolzen in eine Rastöffnung einer Rastschiene einrasten und die Verstelleinrichtung ver­ riegeln kann, während die restlichen, in einer Zahn auf Zahn- Stellung befindlichen Stifte auf der Rastschiene aufsitzen. Beim manuellen Entriegeln werden zunächst die im Eingriff be­ findlichen Rastbolzen angehoben. Nachdem diese auf das Niveau der auf der Rastschiene aufsitzenden Rastbolzen gebracht sind, müssen auch diese zur vollständigen Entriegelung angehoben wer­ den. Dies führt zu einem deutlichen, die Bedienung erschweren­ den Kraftsprung am Betätigungsgriff.From DE-GM 89 13 244 an adjustable vehicle seat be knows whose longitudinal adjustment via a generic Vorrich device can be locked with several locking bolts. The locking bolts are arranged and designed so that in any Sitting position at least one locking pin in a locking opening engage a locking rail and ver the adjustment device can lock, while the rest, in one tooth on dental Position the pins on the locking rail. When manually unlocking the be in engagement sensitive locking bolts raised. After this to the level the locking bolts on the locking rail are brought, these must also be lifted for complete unlocking the. This leads to a clear, difficult operation the jump in strength on the operating handle.

Im weiteren ist aus der DE-OS 23 28 847 eine Einrichtung zum Ent­ sperren einer Verriegelung mittels eines von Hand bedienbaren Hebels bekannt.Furthermore, from DE-OS 23 28 847 a device for Ent lock a lock using a hand-operated Lever known.

Der Erfindung liegt die Aufgabe zugrunde, zur Verbesserung des Bedienkomfortes und zum weitgehenden Ausschluß von Fehlbedienungen eine gattungsgemäße Verriegelung derart auszu­ bilden, daß die zum Entriegeln der Sitzlängsverstellung erfor­ derliche Betätigungskraft über den gesamten Betätigungsweg re­ lativ konstant verläuft und von Hand leicht aufzubringen ist.The invention has for its object to improve the Ease of use and the extensive exclusion of  Operating errors a generic lock in such a way form that needed to unlock the seat adjustment Actual operating force over the entire actuation path re runs relatively constant and is easy to apply by hand.

Erfindungsgemäß wird die Aufgabe mit den Merk­ malen des Patentanspruches 1 gelöst, wobei die Merkmale der Unteransprüche vorteilhafte Aus- und Weiterbildungen kenn­ zeichnen.According to the task with the Merk paint the patent claim 1, the characteristics of Advantageous training and further education to draw.

Durch die erfindungsgemäße Ausbildung und Anordnung der Über­ tragungselemente wird im Verlauf der Entriegelungsbewegung zwischen Handgriff und Riegelvorrichtung eine Änderung des Übersetzungsverhältnisses bewirkt, so daß das im Verlauf der Entriegelungsbewegung mit einem deutlichen Sprung anwachsende aufzubringende Drehmoment am Entriegelungshebel weitgehend kom­ pensiert wird und die erforderliche Betätigungskraft am Hand­ griff nahezu konstant bleibt. Diese Übersetzungsänderung wird im wesentlichen dadurch erreicht, daß an einem von Hand zu be­ tätigenden Betätigungshebel ein Betätigungsnocken angebracht ist, der mit einer an einem Entriegelungshebel angeordneten Kurvenbahn zusammenwirkt.Due to the design and arrangement of the invention Support elements become in the course of the unlocking movement between the handle and locking device a change in Transmission ratio causes, so that in the course of Unlocking movement with a significant jump growing torque to be applied to the release lever largely com is pensiert and the required operating force on hand grip remains almost constant. This translation change will essentially achieved by being on one by hand Actuating operating lever attached an operating cam is the one arranged on a release lever Curve interacts.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt und wird im folgenden näher be­ schrieben.An embodiment of the invention is in the drawing is shown schematically and will be described in more detail below wrote.

Fig. 3 die Ansicht entsprechend Fig. 2 im entriegelten Zustand. Fig. 3 shows the view corresponding to Fig. 2 in the unlocked state.

Eine mit dem Bezugszeichen 1 bezeichnete Verriegelung weist eine fahrzeugfest angebrachte Führungsschiene 2 auf, in der eine am nicht dargestellten Sitz befestigte Sitzschiene 3 in Kugelführungen 4 längsverschiebbar geführt ist. In der ebenen Auflageseite 5 der Führungsschiene 2 sind Rastöffnungen 6 ein­ gearbeitet, die sich über den gesamten Verstellbereich des Sitzes bzw. einer fest an der Sitzschiene 3 befestigten Rie­ gelvorrichtung 7 erstrecken. Die Riegelvorrichtung 7 umfaßt vier parallel zueinander und senkrecht zur Führungsschiene an­ geordnete und in einem Führungsteil 8 geführte Rastbolzen 9. An ihrem oberen Ende, welches sowohl über das Führungsteil 8 als auch über die Sitzschiene 3 hinausragt, weisen die Rastbolzen 9 jeweils einen Tragbund 10 auf, während sich die unteren, gegen die Rastöffnungen 6 gerichteten Endbereiche 11 konisch verjün­ gen.A lock designated by the reference numeral 1 has a guide rail 2 attached to the vehicle, in which a seat rail 3 fastened to the seat (not shown) is guided so as to be longitudinally displaceable in ball guides 4 . In the flat support side 5 of the guide rail 2 locking openings 6 are worked, which extend over the entire adjustment range of the seat or a fixed to the seat rail 3 Rie gel device 7 . The locking device 7 comprises four parallel to each other and perpendicular to the guide rail to ordered and guided in a guide part 8 locking pin 9th At their upper end, which protrudes both over the guide part 8 and over the seat rail 3 , the locking bolts 9 each have a support collar 10 , while the lower end portions 11 directed towards the locking openings 6 taper conically.

In der Ruhestellung der Verriegelung 1 werden die Rastbolzen 9 durch zwei Drehfedern 12 nach unten gegen die Führungsschiene 2 gedrückt, wobei der Abstand der Rastbolzen 9 zueinander im Ver­ gleich zum Abstand der Rastöffnungen 6 zueinander so gewählt ist, daß in jeder Position des Sitzes mindestens ein Rastbolzen 9 sofort einrastet und durch eine minimale, innerhalb der be­ treffenden Rastöffnung 6 möglichen Lageveränderung des bereits eingerasteten Rastbolzens 9 ein zweiter Rastbolzen 9 einrasten kann. Die beiden nicht eingerasteten Rastbolzen 9 stützen sich dabei auf der Auflageseite 5 der Führungsschiene 2 in Bereichen zwischen benachbarten Rastöffnungen 6 ab. Mit dieser Anordnung ist eine sichere und spielfreie Einrastung bzw. Arretierung des Sitzes in praktisch jeder Position seiner Längsverstellung ge­ währleistet.In the rest position of the lock 1 , the locking bolts 9 are pressed down by two torsion springs 12 against the guide rail 2 , the distance between the locking bolts 9 relative to one another in comparison to the distance of the locking openings 6 being chosen such that at least one in each position of the seat latching pin 9 clicks into place immediately and a second stop bolt 9 can engage with a minimum, possible within the opening 6 be taken detent position change of the already latched latching bolt. 9 The two latching bolts 9 , which are not latched in, are supported on the support side 5 of the guide rail 2 in areas between adjacent latching openings 6 . With this arrangement, a secure and play-free engagement or locking of the seat in virtually any position of its longitudinal adjustment is guaranteed.

Zur Betätigung der Rastbolzen 9 ist ein Entriegelungshebel 13 vorgesehen. Dieser Entriegelungshebel 13 ist als zweiarmiger, in einem Schwenklager 14 am Sitz gelagerter Hebel ausgebildet, wobei die Mittellängsachse des Schwenklagers 14 parallel zur Längserstreckung der Führungs- bzw. der Sitzschiene 2, 3 ver­ läuft. An dem den Rastbolzen 9 zugewandte Ende sind in dem Ent­ riegelungshebel 13 schlitzförmige Ausnehmungen 15 eingearbei­ tet, welche unterhalb der Tragbunde 10 die Rastbolzen 9 um­ greifen und mittels derer die Rastbolzen 9 in Öffnungsrichtung gegen die Kraft zweier Drehfedern 12 angehoben werden können. An dem den Rastbolzen 9 abgewandten Ende weist der Entriege­ lungshebel 13 eine Auflage 16 auf, auf der ein Betätigungsnok­ ken 17 eines in Fig. 2 und 3 angedeuteten Betätigungshebels 18 aufliegt, wobei statt des Betätigungsnockens 17 eine Betäti­ gungsrolle angebracht sein kann. Durch eine Zugfeder 19 wird der Entriegelungshebel 13 ständig in Verriegelungsrichtung beauf­ schlagt, so daß in verriegelter Stellung, d. h. in der Ruhestel­ lung der Verriegelung 1 das den Rastbolzen 9 zugewandte Ende des Entriegelungshebels 13 auf der Sitzschiene 3 aufliegt und der Betätigungshebel 18 in einer in Fig. 2 dargestellten Aus­ gangsstellung gehalten ist.An unlocking lever 13 is provided for actuating the locking bolts 9 . This unlocking lever 13 is designed as a two-armed lever mounted in a pivot bearing 14 on the seat, the central longitudinal axis of the pivot bearing 14 running parallel to the longitudinal extent of the guide or seat rail 2 , 3 ver. At the end facing the locking pin 9, slot-shaped recesses 15 are inserted into the locking lever 13 , which engage the locking pin 9 below the support collars 10 and by means of which the locking pin 9 can be raised in the opening direction against the force of two torsion springs 12 . At the end facing away from the locking pin 9 , the unlocking lever 13 has a support 16 on which an actuating cam 17 of an actuating lever 18 indicated in FIGS. 2 and 3 rests, wherein instead of the actuating cam 17 an actuating roller can be attached. By a tension spring 19 , the unlocking lever 13 is constantly struck in the locking direction, so that in the locked position, ie in the rest position of the locking 1, the locking pin 9 facing the end of the unlocking lever 13 rests on the seat rail 3 and the actuating lever 18 in a in Fig from illustrated. 2 is held gear position.

Der Betätigungshebel 18 ist ebenfalls als zweiarmiger Hebel mit einer sitzfest angeordneten Lagerstelle 24 ausgebildet, wobei die dem Betätigungsnocken 17 abgewandte Seite des Betätigungs­ hebels 18 einen Handgriff 25 aufweist, der von einer im Sitz sitzenden Person leicht greif- und betätigbar ist. Zum Ent­ riegeln der Sitzlängsverstellung wird der Handgriff 25 des Be­ tätigungshebels 18 nach oben gezogen, wodurch sich der Betäti­ gungsnocken 17 um die Lagerstelle 24 nach unten verschwenkt. Über die Auflage 16 überträgt sich die Schwenkbewegung auf den Entriegelungshebel 13, der damit seinerseits um sein Schwenk­ lager 14 schwenkt.The actuating lever 18 is also formed as a two-armed lever with a seat 24 arranged in a seat-fixed manner, the side of the actuating lever 18 facing away from the actuating cam 17 having a handle 25 which can be easily gripped and actuated by a person sitting in the seat. To unlock the seat longitudinal adjustment, the handle 25 of the actuation lever 18 is pulled upwards, whereby the actuation cam 17 pivots about the bearing 24 downwards. Via the support 16 , the pivoting movement is transferred to the unlocking lever 13 , which in turn pivots about its pivot bearing 14 .

Dabei ist der Entriegelungshebel 13 so gestaltet und angeord­ net, daß beim Verschwenken innerhalb des Verschwenkbereiches eine relativ große Längsverschiebung des Betätigungsnockens 17 auf der Auflage 16 eintritt. Diese Verschiebung kann durch die Anordnung des Schwenklagers 14 im Bezug auf die Schwenklinie des Betätigungsnockens 17 bzw. der Hebel 13, 18 zueinander vor­ teilhaft dimensioniert werden.The unlocking lever 13 is designed and angeord net that a relatively large longitudinal displacement of the actuating cam 17 occurs on the support 16 when pivoting within the pivoting range. This displacement can be dimensioned by the arrangement of the pivot bearing 14 in relation to the pivot line of the actuating cam 17 or the lever 13 , 18 to each other before geous.

Die Schwenkbewegung des Entriegelungshebels 13 wird über die an der Unterseite der Tragbunde 10 anstehenden Aussparungen 15 auf die Rastbolzen 9 übertragen.The pivoting movement of the unlocking lever 13 is transmitted to the locking bolts 9 via the cutouts 15 on the underside of the support collars 10 .

In einem ersten Hubbereich "a" werden zunächst nur die beiden Rastbolzen 9 angehoben, welche in die Rastöffnungen 6 eingera­ stet waren. In einen zweiten, an den ersten Hubbereich "a" an­ schließenden Hubbereich "b" werden alle vier Rastbolzen 9 wei­ ter an- bzw. von der Führungsschiene 2 abgehoben. In diesem zweiten Hubbereich "b" ist, infolge der im Vergleich zum ersten Hubbereich "a" doppelten Anzahl der gegen die Kraft der Dreh­ federn 12 anzuhebenden Rastbolzen 9 das doppelte Drehmoment am Entriegelungshebels 13 erforderlich.In a first stroke range "a", only the two locking bolts 9 , which were inserted into the locking openings 6, are initially raised. In a second, to the first stroke range "a" to the closing stroke range "b", all four locking bolts 9 are further raised or lifted off the guide rail 2 . In this second stroke range "b" due to the double compared to the first stroke region "a" number of against the force of the torsion springs 12 to be lifted locking pin 9 twice the torque at the unlocking lever 13 is required.

Um zu verhindern, daß sich der daraus resultierende deutliche Anstieg der Betätigungskraft des Entriegelungshebels 13 auf die manuell aufzubringende Betätigungskraft an Betätigungshebel 18 negativ auswirkt, ist die Auflage 16 im Bereich der Verschie­ bung des Betätigungsnockens 17 erfindungsgemäß als Kurvenbahn 20 gestaltet.In order to prevent the resulting significant increase in the actuating force of the unlocking lever 13 having a negative effect on the manually applied actuating force on the actuating lever 18 , the support 16 in the region of the displacement of the actuating cam 17 is designed according to the invention as a cam track 20 .

In einem dem Schwenklager 14 zugewandten ersten Abschnitt 21 weist die Kurvenbahn 20 einem im wesentlichen quer zur Richtung der Schwenkbewegung des Betätigungsnockens 17 angeordneten Ver­ lauf auf. Dieser Abschnitt 21 umfaßt den Verschiebebereich des Betätigungsnockens 17 auf der Auflage 16 im ersten Hubbereich "a" der Rastbolzen 9. Das dadurch bewirkte Übersetzungsverhält­ nis ergibt beim Aufbringen der erforderlichen Betätigungskraft einen, im Verhältnis zum Betätigungsweg am Handgriff 25 relativ großen Hubweg der Rastbolzen 9.In a first section 21 facing the pivot bearing 14 , the cam track 20 has a substantially transverse to the direction of the pivoting movement of the actuating cam 17 arranged Ver run. This section 21 comprises the displacement area of the actuating cam 17 on the support 16 in the first stroke area "a" of the locking bolts 9 . The resulting translation ratio results in the application of the required actuation force, a relatively large stroke distance of the locking pin 9 in relation to the actuation path on the handle 25 .

Ein an den ersten Abschnitt 21 anschließender, eben verlaufen­ der zweiter Abschnitt 22 der Kurvenbahn 20, über dem sich der Betätigungsnocken 17 beim Anheben aller vier Rastbolzen 9 im zweiten Hubbereich "b" verschiebt, verläuft in (Entriegelungs-) Schwenkrichtung geneigt, wobei der Übergang des Betätigungsnoc­ kens 17 vom ersten Abschnitt 21 in den zweiten Abschnitt 22 im Moment des Überganges in den zweiten Hubbereich "b" der Rast­ bolzen 9 erfolgt.A connecting to the first section 21 , the second section 22 of the cam track 20 , over which the actuating cam 17 moves when all four locking bolts 9 are lifted in the second stroke range "b", runs inclined in the (unlocking) pivoting direction, the transition of the actuating cam 17 from the first section 21 into the second section 22 at the moment of transition into the second stroke range "b" of the locking bolt 9 .

Infolge der Neigung der Kurvenbahn 20 zur Schwenkrichtung des Betätigungsnockens 17 muß der Betätigungsnocken 17 in diesem zweiten Abschnitt 22 der Kurvenbahn 20 zur Erzielung eines be­ stimmten Schwenkwinkels des Entriegelungshebels 13 einen grö­ ßeren Schwenkweg zurücklegen als im ersten Abschnitt 21 der Kurvenbahn 20.Due to the inclination of the cam track 20 to the pivoting direction of the actuating cam 17 of the actuating cam 17 must for achieving be in this second section 22 of the cam track 20 voted pivot angle of the release lever 13, a RESIZE ßeren pivoting cover than 21 in the first section of the cam track 20th

Mit dieser Übersetzung innerhalb des zweiten Hubbereiches "b", die sich beim Schwenken des Betätigungshebels 18 einerseits in einer Verminderung des am Entriegelungshebel 13 bewirkten Schwenkwinkels sowie andererseits im umgekehrten Verhältnis in einer Vergrößerung des am Entriegelungshebel 13 bewirkten Schwenkmomentes auswirkt, wird die erforderliche Betätigungs­ kraft vermindert, wobei sich der erzielte Hubweg der Rastbolzen 9 entsprechend vermindert.With this translation within the second stroke range "b", which affects the pivoting of the actuating lever 18 on the one hand in a reduction in the pivoting angle caused on the unlocking lever 13 and on the other hand in reverse proportion in an increase in the pivoting moment caused on the unlocking lever 13 , the required actuating force is reduced , wherein the stroke length of the locking pin 9 is reduced accordingly.

Trotz der sich im Verlauf des Hubweges "a" und "b" der Rastbol­ zen 9 ändernden erforderlichen Hubkraft wird infolge der sich beim Überfahren der Kurvenbahn 20 durch den Betätigungsnocken 17 ändernden Übersetzung ein nahezu konstanter Verlauf der er­ forderliche Betätigungskraft erreicht.Despite the fact that in the course of the stroke "a" and "b" of the Rastbol zen 9 changing required lifting force, an almost constant course of the required actuating force is achieved as a result of the changing ratio when driving over the cam track 20 by the actuating cam 17 .

In die exakte Dimensionierung der Übersetzungsverhältnisse fließen neben der konkretem Gestaltung der Kurvenbahn 20 solche Faktoren wie die Form des Betätigungsnockens 17, die geome­ trische Gestalt bzw. die Anordnung des Entriegelungs- und des Betätigungshebel 13, 18 mit ein.In the exact dimensioning of the gear ratios, in addition to the specific design of the cam track 20, such factors as the shape of the actuating cam 17 , the geometric shape or the arrangement of the unlocking and actuating lever 13 , 18 also flow with.

Zur Sicherung gegen unbeabsichtigtes Ausrasten des Betätigungs­ nockens 17 vom Ende der Auflage 16 und zur Begrenzung des Hub­ weges der Rastbolzen 9 kann die Kurvenbahn 20 in einem dritten Abschnitt 23 nochmals entgegen der (Entriegelungs-) Schwenk­ richtung abgeknickt sein.To secure against unintentional disengagement of the actuating cam 17 from the end of the support 16 and to limit the stroke of the locking pin 9 , the cam track 20 can be bent again in a third section 23 against the (unlocking) pivoting direction.
