Description

Sitzgestell, insbesondere für Kraftfahrzeuge Die-Erfindung betrifft ein Sitsgestell, insbesondere für Kraftfahrzeuge, dessen Sitzrahmen zwecks Längsverschiebung -vorn mittels einen durch eine Verriegelungseinrichtung arretierbaran Lenkerpaares am Boden angelenkt ist und hinten auf einem Paar Stützen ruht. Ein solchen Sitzge- stell ist beispielsweise in der gleichseitig von der Anmelderin eingereichten Anmeldung mit der Reg. Nr. 120 161 näher beschrieben. Seat frame, in particular for motor vehicles The invention relates to a seat frame, in particular for motor vehicles, the seat frame of which, for the purpose of longitudinal displacement, is articulated to the front by means of a pair of handlebars that can be locked by a locking device and rests on a pair of supports at the rear. Such a seat frame is described in more detail , for example, in the application filed at the same time by the applicant with Reg. No. 120 161.

Bei einen solchen Sitzgestell hat der vordere Teil des Sitzes an sich eine Höhe, die, abgesehen von den konstruktivon Daten" abhängig ist von der Stellung des Sitzes in der Längsrichtung, weil die oberen Enden des Lenkerpaares bei der Verstellung des Sitzes in der Längsrich- tung sich auf Kreisbögen bewegen. In such a seat frame, the front part of the seat at a height which, apart from the konstruktivon data "depending on the position of the seat in the longitudinal direction, because the upper ends of the link pair in the adjustment of the seat in the longitudinal direction move on arcs of a circle.

Der Erfindung liegt die Aufgabe zu Grunde, trotz dieser verschiedenen, durch die Stellung des Sitzes in Längsrichtung gegebenen Höhen des vorderen Teiles des Sitzes die Höhe desselben unabhängig davon zur Anpassung an die Figur des Benutzers des Sitzes einstellen zu können. The invention is based on the object of being able to adjust the height of the front part of the seat independently of these different heights of the front part of the seat, given by the position of the seat in the longitudinal direction, in order to adapt to the figure of the user of the seat.

Diese der Erfindung zu Grunde liegende Aufgabe wird dadurch gelöst, daß die oberen Enden der Lenker je über einen Zwischen- lenker am Sitzrahmen angelenkt sind, daß mindestens ein Zwischenlenker mittels einer Verstelleinrichtung um seine An- lenkungsachse am Gestell drehbar angeordnet ist und dab eine Einrichtung zur Sicherung des Gleichlaufes der beiden Zwischen- lenker vorgesehen ist. This object of the invention underlying is achieved in that the upper ends of the links are each articulated via an intermediate link to the seat frame, that at least one intermediate link by means of an adjusting device about its arrival steering axis is rotatably arranged on the frame and dab means for Ensuring the synchronization of the two intermediate links is provided.

Die Einstellbarkeit der Höhe ermöglicht auch einen wesentlich größeren Verstellbereich des Sitzes in Längsrichtung vorzu- sehen als bei den bekannten, Lenker verwendenden Sitzen, bei denen der Verstellbereich durch die noch zulässige Höhen-änderung des Sitzes begrenzt ist. The adjustability of the height also makes it possible to provide a significantly larger adjustment range of the seat in the longitudinal direction than in the case of the known seats using handlebars, in which the adjustment range is limited by the still permissible change in height of the seat.

Die Verstelleinrichtung ist zweclcnäßigerweise dauernd formschlüs- sig oder kraftschlüssig ausgebildet. Beispielsweise sind Verstell- einrichtungen anwendbar, die in den Patentaruneldungen St 18 952 11/63c (DAS 1 2o4 542) und St 19 ?63 II/63c der Anmelderin be- schrieben sind. The adjustment device is designed to be permanently positively or non-positively. For example, adjusting means applicable to the Applicant are written in the loading Patentaruneldungen St 18 952 11 / 63c (DAS 1 542 2O4) and St 19? 63 II / 63c.

Vorzugsweise werden das Lenkerpaar, die Zwischenlenker, die festen Stützen und die Verstelleinrichtung so bemessen und angeordnet, d,13 die festen Stützen bei der Höhenverstellung des vordren Teiles des Sitzrahmens ihre Stellung zum Boden beibehalten, Das wird dadurch erreicht" dass für-die Bahn der oberen Gelenke des Lenkerpaares ein Kreisbogen gewählt wird um. eine hinter diesen Gelenken liegende horizontale Achse, in der die Zwischenlenker am Sitzgestell angelenkt sind, Die Bahnen der oberen Gelenke, die an sich eine Kurvenschar bilden, sind also hierbei durch eine Kreisbahn angenähert, und der Anlenkpunkt der Zwischenlenker am Sitzgestell ist in einem solchen Abstand und einer solchen Lage bezüglich der oberen Gelenke gewählt, dass er im Mittelpunkt dieser Kreisbahn liegt, Vorteilhafterweise wird auch eine Möglichkeit für die Verstellung des hinteren Teiles des Sitzes vorge- sehen, die jedoch zweekmässigerweise so ausgebildet ist, dass die Versteileinrichtungen für den vorderen und den hinteren Sitzteil im wesentlichen unabhängig voneinander sind, Eine solche Höhenverstellung des hinteren Teiles des Sitzrahmens kann dadurch erreicht werden, dass die festen Stützen je einen nach vorn aus- ladenden Teil aufweisen, der am Sitzgestell angelenkt ist und dass der hintere feil des Sitzrahmens mittels einer Rastvorrichtung höhenverstellbar an den oberen Enden der Stützen angeordnet ist. Preferably, the pair of links, the intermediate links, the fixed supports and the adjustment device are dimensioned and arranged in such a way that the fixed supports maintain their position on the ground when the front part of the seat frame is adjusted in height upper joints of the pair of links an arc is chosen around a horizontal axis behind these joints in which the intermediate links are hinged to the seat frame pivot point of the intermediate link on the seat frame of the upper joints is at such a distance, and such a position with respect to selected such that it is located in the center of this circular path, is advantageously also a possibility for the adjustment of the rear portion see superiors of the seat, but zweekmässigerweise so formed is that the adjustment devices for the front and The rear seat part are essentially independent of one another . Such a height adjustment of the rear part of the seat frame can be achieved in that the fixed supports each have a forward- projecting part that is hinged to the seat frame and that the rear part of the seat frame by means of a Latching device is arranged adjustable in height at the upper ends of the supports.

Die beiden Lenker 6 können die rechtwinklig abgekröpften Enden einer in den Lagern 9 gelagerten Welle 10 bildenö Die Lenker 6 sind an ihren oberen Enden mittels Gelenken Z je an einem Zwischenlenker 19 angelenkto Jeder Zwischen- lenker 19 ist in einem am Sitzrahmen 1 angeordneten Lager 20 gelagerte Der Gleichlauf der beiden Lenker 19 ist im Aus- führungsbeispiel dadurch gesichert, dass sie beide fest auf einer Welle 21 sitzen, die in den Lagern 20 gelagert ist, Auf dem einen Zwischenlenker sind auf einem ICreinbogen um die Achse des Lagern 20 Zapfen 22 angeordnet, die je einen Hund 221 aufweisen, An einer am Sitzrahmen 1 mittels eines Bolzens 23# gelagerten Scheibe 23 ist rechtwinklig abstehend eine Rippe 24 angeordnet, die spiralförmig verläuft. Die Bolzen 22 sind am Zwischenlunker 19 so angeordnet, dass die Rippe 24 jeweils zwischen zwei Bolzen 22 hindurchläuft o Mittels dieser Verstelleinrichtung können also dle Zwischenlenke= 19 um 13,e Gelenke 7 der° Lenker ö geschwenkt werden, die mittels einer besonderen Vorrichtung arretiert sind, wenn der Sitz nicht in der Längsrichtung bewegt werden soll o Selbstverständlich kann die Verstelleinrichtung auch in anderer Weise ausgebildet sein, beispielsweise als Ge®@ windespindel oder als hydraulisches oder pneumatisches Zylinder-Kolben Aggregats Beim Schwenken der Zwischenlenker um die Gelenke 7 bewegen sich die hager 20 auf Kreisbögenstücken, die annähernd senkrecht verlaufen, so dass also bei der Höhenverstellung des vorderen Teiles des Sitzes praktisch keine Längsverschiebung desselben stattfindet, Die A=°eticxzvcixx@.c.;"@@ang tür clae Lenker 6 besheiat, :Lm wesent- licher aus einem an dem einen Lenker 6 in einem Gelenk 79 angelenkten Rasthebel 141, der einen Iaängsschtitz 17 und Rasten 18 aufweist, in denen ein am Gestell fest angeordneter Rast- bolzen 16 verstellbar angeordnet ist, Diesen Arret iervorrichtung ist in der von der Anmelderin gleichzeitig e ingereicht$n An- meldung mit der Reg o Nr o 120 181 näher beschrieben. Der h Lntore Teil des Si tzä^et@4inetia ruht a.tt t fe iten Stützen 1.1, die als gegen eire Abheben nach oben gesicherte Kuren auageleildet sind und je einen nach vorn ausladt:r4üen 'feil 1.2 aufweisen, vier mittels eines Gelenkes 13 ant :111,a;t@ahmeri 1 angelenkt Ist ,# Letzterer ,rta ici t auf' be irlrzn :@u Reit ,IP an t' einem Kreisbogen um die Achse des Gelenkes 13 angeordnete Löcher 15 auf, in die, wie Figo 3 zeigt, wahlweise je ein Bolzen 26 einsteckbar ist, der durch eine Bohrung der festen Stütze 11 hindurchgeht, Auf diese Weise kann der hintere Teil des Sitzrahmens 1 in der Höhe verstellt werden, Die beiden Bolzen 26 sind axial verschiebbar in einem Rohr 27 gelagert, das sich von der Innenseite der einen zur Innenseite der anderen Stütze 11 erstreckt und mit diesen fest verbunden ist, Die beiden Bolzen 26 sind je mit einem radialen Stift 28 bzwo 29 versehen, die annähernd in einer horizontalen Ebene liegen und durch Längsschlitze 30 bzw, :31 des Rohres 2? nach aussen ragen, Die axiale Länge der Schlitze 30 und 31 ist so gewählt, dass die Bolzen 26 1n der einen Endlage in der Verriegelungsstellung stehen (F19,3), in der sie in die Löcher 15 des Sitzrahmenteil ragen, und dass sie in der anderen Endstellung in der Entriegelungsstellung stehen, in der sie vollständig aus den Löchern 15 herausgezogen sind. Um die beiden Bolzen 26 bequem gleichzeitig betätigen zu können, ist der gegenseitige Abstand der Stifte 28 und 29 so gewählt, dass sie mit dem Daumen und einem weiteren Finger bequem erfasst und gegeneinander gedrilckt werden können. Eine zwischen den einander zugekehrten Stirnseiten der Bolzen 26 angeurdriete vorgespannte Schraubenfeder 32 sucht di.e Bolzen 26 in der Verriegelungsstellung zu halten, Eine andere Ausführungsform einer Vorrichtung zum Einstellen der Höhe des hinteren Sitzteils zeigen die Figo 4 und 5, Hier ist je das obere Ende der beiden hinteren Stützen 111, die auf der Aussenseite des Sitzrahmens 1 anliegen, mit Löchern 15' versehen, die auf einem Kreisbogen um die Achse der nicht dargestellten, den Gelenken 13 entsprechenden Gelenken angeordnet sind. Wie insbesondere Viga 5 zeigt, sind die Löcher 15t durch einen auf dem Kreisbogen liegenden Schlitz 33 miteinander verbunden, so däss die Löcher 15' zu dem Schlitz 33 hin offene Nuten bilden, Ferner sind die@Löcher 15# als konische, sich gegen den Sitzrahmen i hin verjüngende Bohrungen ausgebildet, Der Sitzrahmen 1° ist auf dem selben Kreisbogen auf dem der Schlitz 33 liegt, auf jeder Seite mit einer Gevindebohrung*versehen, in die je eine Schraube 34 eingeschraubt ist, Der Durchmesser der Schraube 34 ist höchstens gleich der Breite des Schlitzes 33o Wie Figo 4 zeigt, ist der obere Schaftteil 34# der Schraube 34 konisch entsprechend der Form der Löcher 15' ausgebildet. Mittels eines Flügel- kopfes 35 kann die Schraube 34 bequem von Hand gedreht werden, Zum Feststellen des Sitzrahmens 11 in der gevünackbsn Höhe wird auf jeder Seite die Schraube 34 festgezogen,. Durch die konische Ausbildung der Löcher 159 und den oberen Schaftteils 34# erzielt man eine gute Pressung zwischen der Innenfläche der Stütze 11 und der Aussen.. fliehe des Sitzrahmens i#, Zum Verändern der Sitzhöhe werden die Schrauben 34 soweit aus der Gewindebohrung herausgedreht, dass die Schraube 34 in Längsrichtung den Schlitzen 33 verschoben werden kann. Zur Pest. stellung in der neuen Lage werden dann lediglich die Schrauben 34 wieder festgezogen, Der Vorteil dieser AusfUhrungsforn besteht vor allem in ihren konstruktiv einfachen Aufbau, der eine Herstellung mit verhältnissRssig geringen Xosten ermöglicht. 1 shows a side view of the seat frame, FIG. 2 shows a front view of the seat frame, FIG. 3 shows a section of the height adjustment device. the rear part of the seat frame, Fige 4 is an arrival partially sectioned view of another embodiment of a height adjustment device of the rear part of the seat frame, Figure 5 is a side view of the upper end of a rear support for a formation of the Höhenverstelleihrichtung according to FIG. 4, the seat frame according to the invention includes a seat frame 1, on which the seat cushion 2 is arranged, by means of a hinge fitting 3,4 is articulated the back 5, on both sides of vörderen part of the seat frame 1 handlebar 6 are hinged to the bottom 8 by means of bearings. 9 The two links 6, the right angle angled ends a shaft mounted in the bearings 9 shaft 10 bildenö the link 6 are connected at their upper ends by means of joints Z are each at an intermediate link 19 angelenkto Each intermediate link 19 is mounted in a cylinder disposed on the seat frame 1 bearing 20 the synchronization of the two link 19 is in the exemplary example secured in that they sit both on a shaft 21 which is mounted in bearings 20 on which an intermediate link are arranged on a ICreinbogen about the axis of the bearings 20 journal 22, each of which has a dog 221.

In order to be able to conveniently actuate the two bolts 26 at the same time, the mutual spacing of the pins 28 and 29 is selected so that they can be comfortably grasped and pressed against one another with the thumb and another finger. A pretensioned helical spring 32, which is connected between the facing end faces of the bolts 26, seeks to hold the bolt 26 in the locking position. Another embodiment of a device for adjusting the height of the rear seat part is shown in FIGS. 4 and 5, here is the upper end of the two rear supports 111, which rest on the outside of the seat frame 1, are provided with holes 15 ' which are arranged on an arc of a circle around the axis of the joints, not shown, corresponding to the joints 13. As Viga 5 in particular shows, the holes 15t are connected to one another by a slot 33 lying on the arc of a circle , so that the holes 15 ' form grooves open towards the slot 33. Furthermore, the holes 15 # are conical, facing the seat frame i formed tapering bores , the seat frame 1 ° is on the same arc on which the slot 33 is, provided on each side with a threaded hole *, in each of which a screw 34 is screwed, the diameter of the screw 34 is at most equal to the width of the slot 33o As FIG. 4 shows, the upper shaft part 34 # of the screw 34 is conical in shape according to the shape of the holes 15 '. By means of a wing screw head 35 can be easily turned by hand 34, for locking the seat frame 11 in the gevünackbsn height, the screw 34 is tightened at each side ,. Due to the conical shape of the holes 159 and the upper shaft part 34 # is obtained a good pressure between the inner surface of the support 11 and the outer .. flee of the seat frame i #, the screws 34 are to change the seat height so far rotated out of the threaded bore that the screw 34 can be moved in the longitudinal direction of the slots 33 . To the plague. position in the new location are then only the screws tightened 34 again, The advantage of this is AusfUhrungsforn especially in their simple construction, the m a manufacture it verhältnissRssig low Xosten possible.
