Description

Die Erfindung betrifft eine durch Kleinmgesperre sich selbsttätig feststellende Einstellvorrichtung und hat den Zweck, eine derartige Vorrichtung zu ergeben, daß sie besonders für Kraftwagensitze und deren Lehnen geeignet ist: Hierbei kommt es auf eine billig herzustellende, aber doch betriebssichere und vor allem wenig Raum einnehmende Bauart an. Sie soll zu diesem Zweck aus möglichst wenig Einzelteilen bestehen, um jedes von diesen reichlich bemessen zu können. Erwünscht ist es, wenn sich das Bedienungsglied seitlich unten am Sitz befindet, damit es einesteils nicht stört oder unabsichtlich betätigt werden kann und andernteils vielgliedrike und umständliche Gestänge vermieden werden. Ein solches Bedienungsglied wird dann zweckmäßig als Knopf ausgebildet, damit es in jeder Stellung gleichmäßig für die Bedienung griffbereit ist und nicht wie eine Kurbel günstige und ungünstige Lagen einnimmt. Um zu der Verstellung des Sitzes keine übermäßige Kraft aufwenden zu müssen, ist dabei ferner ein Vorgelege zwischen dem Griff und dem zu verstellenden Teil vorteilhaft. Dieses Vorgelege ergibt ein Mittelglied, das weder mit dem Antriebsgriff noch mit dem Verstellteil unmittelbar in Verbindung stehen muß und bietet dadurch die Möglichkeit zu der Erfindung, die darin besteht, daß die mit dem Bedienungsknopf zu drehende Triebwelle mit Knagg@en einen von zwei Kloben verschiebt, die an einem locker auf der Triebwelle beweglichen Ritzel sitzen und in ihrer Ruhelage durch Federwirkung in ihrem Gehäuse festgeklemmt werden. Die Einrichtung gemäß der Erfindung ist in der Lage, die verhältnismäßig 'hohen Beanspruchungen auszuhalten, welche bei den starken Beschleunigungen entstehen, .die sich sowohl durch die stoßweise Belastung des Sitzes von einem sich heftig niedersetzenden Benutzer als auch durch ein ruckweises Verstellen des Bedienungsgriffes ergeben.The invention relates to a self-acting by Kleinmgesperre locking adjustment device and has the purpose of such a device to show that it is particularly suitable for vehicle seats and their backrests: Here it comes to a cheap to manufacture, but safe and reliable before all construction that takes up little space. To this end, it should use as little as possible Individual parts exist in order to be able to measure each of these abundantly. He wishes it is when the operating member is on the side below the seat so that it on the one hand does not interfere or can be accidentally actuated and on the other hand multiple limbs and cumbersome linkages are avoided. Such an operating member is then expediently designed as a button so that it is uniform for the in every position Operation is within easy reach and not favorable and unfavorable positions like a crank occupies. In order not to have to use excessive force to adjust the seat, is also a lay-up between the handle and the part to be adjusted advantageous. This back gear results in a middle link that neither connects to the drive handle still has to be directly connected to the adjustment part and offers thereby the possibility of the invention, which consists in that with the control button to be rotated drive shaft with Knagg @ en moves one of two cocks that on one sit loosely on the drive shaft movable pinion and through in its rest position Spring action are clamped in their housing. The device according to the invention is able to withstand the relatively high stresses which with the strong accelerations arise, which are caused by both the intermittent Load on the seat from a user who sat down violently as well as from result in a jerk adjustment of the operating handle.

Die Zeichnung stellt ein Ausführungsbeispiel der Erfindung dar, und zwar zeigt Abb. i eine Sesseleinstelleinrichtung in Ansicht, Abb. 2 dieselbe im Schnitt nach Linie a-a der Abb. i und Abb. 3 und 4 in größerem Maßstab einen Schnitt nach Linie b-b der Abb. 2 in verschiedenen Arbeitsstellungen.The drawing shows an embodiment of the invention, and although Fig. i shows a chair adjustment device in view, Fig. 2 shows the same in Section along line a-a of Fig. I and Fig. 3 and 4 on a larger scale a section according to line b-b of Fig. 2 in different working positions.

An einem nicht dargestellten Sessel sind die beiden Schenkel der Einstellvorrichtung angeschraubt, und zwar der feststehende Schenkel i an dem Sitz, der um den Zapfen 2 gegen den Sehenkel i drehbare andere Schenkel 3 aber an der Lehne des Sessels. Auf dem Schenkel 3 ist eine Kappe 4 mit Schrauben 5 befestigt. In dem Schenkel 3 und der Kappe 4 ist die Welle 6 des Ritzels 7 gelagert, das in den Zghubogen 8 des Schenkels i ,eingreift. Auf ihr ist ein großes Zahnrad 9 aufgekeilt. Ferner ist im Schenkel 3 und der Kappe 4 die Welle io gelagert, die auf ihrem herausragenden Ende den Vierkant i i aufweist, auf den der Knopf 12 aufgesetzt ist. Die Welle i o trägt das Ritzel 13, dessen Bohrung ein wenig größer ist als der Durchmesser der Welle to, so daß es locker sitzt und sich radial etwas verschieben kann.On an armchair, not shown, the two legs of the adjustment device are screwed, namely the fixed leg i on the seat, the other leg 3 rotatable about the pin 2 against the leg i but on the back of the chair. On the leg 3, a cap 4 is fastened with screws 5. In the leg 3 and the cap 4, the shaft 6 of the pinion 7 is mounted, which engages in the Zghubogen 8 of the leg i. A large gear 9 is keyed on it. Furthermore, the shaft io is mounted in the leg 3 and the cap 4, which has the square ii on its protruding end, onto which the button 12 is placed. The shaft i o carries the pinion 13, the bore of which is a little larger than the diameter of the shaft to, so that it sits loosely and can move slightly radially.

Auf der Welle io ist ferner der Knaggen 14 aufgekeilt. Das Ritzel 13 besitzt zwei Kloben 15, die sich in der gleichen Zone befinden wie der Knaggen i 4 und daher von diesem erfaßt werden, wenn die Welle io mittels des Knopfes 13 gedrejht wird. Im Ruhestand dagegen stehen sie unter der Einwirkung der über die Rollen 16 wirksamen Feder 17. Die Wirkung dieser Feder 17 in der Ru7helage ist in Abb.3 durch Pfeile veranschaulicht. Danach legt sich der Mittelteil der Feder gegen die Innenwand der Kappe 4, während die Federenden die Walzen 16 gegen die beiden Kloben 15 drücken und diese bei der Verschiebbarkeit des Ritzels 13 gegen die Welle io an die Innenwand der Kappe 4 anpressen. Hierdurch wird das Ritzel 13 festgehalten und kann keine Drehung durch Stöße erfahren, die von dem Schenkel 3 über das Vorgelege 8, 7, 9 erfolgen.The lug 14 is also keyed on the shaft io. The pinion 1 3 has two clamps 1 5 which are located in the same zone as the dog 4 and are therefore caught by this when the shaft 10 is rotated by means of the button 13. In retirement, however, they are under the action of the spring 17 acting on the rollers 16. The action of this spring 17 in the rest position is illustrated in Figure 3 by arrows. Thereafter, the central part of the spring sets against the inner wall of the cap 4, while the spring ends press 1 6 against the two clamp 1 5, the rolls and pressing them in the displacement of the pinion 13 against the shaft io to the inner wall of the cap. 4 As a result, the pinion 13 is retained and cannot experience any rotation due to impacts which occur from the leg 3 via the countershaft 8, 7, 9.

Wird aber die Welle io im einen oder anderen Sinne gedreht, so wird, wie Abb. 4 zeigt, der eine Kloben 15 von der Wand der Kappe 4 gegen die Wirkung der Feder 17 abgehoben. Der andere Kloben liegt dann nur noch mit einer Ecke an der Wand der Kappe 4 an, indem das ganze, locker auf der Welle i o sitzende Ritzel 13 etwas um diesen Anlegepunkt geschwenkt wird. Es läßt sich daher mittels des Knaggens 14 leicht verschieben, so daß der Schenkel 3 über das Vorgelege 9, 7, 8 gedreht werden kann, ohne daß noch eine Selbsthemmung zu überwinden ist.However, if the shaft io rotated in one sense or another, so, as Fig. 4 shows the lifted a clamp 1 5 of the wall of the cap 4 against the action of the spring 17. The other block then only rests with one corner on the wall of the cap 4, in that the entire pinion 13, which is loosely seated on the shaft, is pivoted a little about this contact point. It can therefore be easily displaced by means of the lug 14 so that the leg 3 can be rotated via the intermediate gear 9, 7, 8 without a self-locking still having to be overcome.
