Abstract

Seat adjustment, especially for a motor-vehicle seat, comprising an adjustable seat underframe carrying a seat, as well as at least one adjusting motor which is connected to the seat underframe via at least one drive connection having two gear parts engaging in one another, if appropriate with play, in which seat adjustment, according to Patent Application P 3102402, a friction brake is provided which has a brake block which surrounds the outer circumference of a shaft and which keeps the gear parts against one another in the event of an adjusting movement of the seat underframe taking place in a first direction and assisted by a seat force exerted on the seat underframe by the seat, characterised in that the brake block has two clamping arms which are clamped together by a clamping member via a spring arrangement.

Description

Sitzverstellung, insbesondere für einen Kraftfahrzeugsitz Seat adjustment, in particular for a motor vehicle seat

Die Erfindung betrifft eine Sitzverstellung nach dem Oberbegriff des Anspruchs 1.The invention relates to a seat adjustment according to the preamble of Claim 1.

Der Bremsblock nach der Patentanmeldung P 31 o2 4c2 kann in einer bevorzugten Ausführungsform stufenweise nachgestellt werden, um eine Bremswirkungsanpassung, aber auch eine Verschleißanpassuna zu ermöglichen.The brake block according to the patent application P 31 o2 4c2 can be in a preferred embodiment can be readjusted in stages in order to adjust the braking effect, but also to enable a wear adjustment.

Aufgabe der Erfindung ist es, eine selbsttätige Nachstellung des Bremsblocks zur Verschleißanpassung zu erreichen.The object of the invention is to provide an automatic readjustment of the brake block to achieve wear adjustment.

Die Lösung dieser Aufgabe ist im Kennzeichen des Anspruchs 1 angegeben.The solution to this problem is given in the characterizing part of claim 1.

Selbstverständlich nimmt bei einem Verschleiß,der zum Zusammenspannen der Spann arme unter der Wirkung der Federanordnung führt, die Bremswirkung etwas ab. überraschenderweise spielt jedoch diese Abnahme der Bremswirkung während der üblichen Lebensdauer einer Sitzverstellung keine Rolle.It goes without saying that when there is wear and tear, that leads to clamping the clamping arms under the action of the spring assembly leads to the braking effect somewhat away. Surprisingly, however, plays this decrease in braking effect during the normal service life of a seat adjustment does not matter.

Um den Bremsblock auch willkürlich zur Einstellung einer gewünschten Bremskraft einstellen zu können, ist bevorzugt eine Ausbildung gemäß Anspruch 2 vorgesehen. Diese Ausbildung hat noch den Vorteil, daß das Spannglied das Bauvolumen praktisch nicht vergrößert.To set the chock also arbitrarily to a desired one To be able to adjust the braking force is preferably an embodiment according to claim 2 intended. This training also has the advantage that the tendon takes up the structural volume practically not enlarged.

Eine besonders einfache Nachstellmöglichkeit des Bremsblocks ist bei einer Ausbildung gemäß Anspruch 3 gegeben.A particularly simple adjustment option for the brake block is at given a training according to claim 3.

Als besonders zweckmäßig hat sich eine Federanordnung entsprechend Anspruch 4 erwiesen.A spring arrangement has accordingly proven to be particularly useful Claim 4 proved.

Die Erfindung wird im folgenden an einem Ausführungsbeispiel unter Hinweis auf die beigefügte Zeichnung erläutert.The invention is illustrated below using an exemplary embodiment Reference to the attached drawing explained.

Die Zeichnung zeigt einen im wesentlichen U-förmiaen Bremsblock 2, der einen Bremsring4 an den Außenumfang einer Welle 6 drückt.The drawing shows a substantially U-shaped brake block 2, which presses a brake ring 4 against the outer circumference of a shaft 6.

Der Bremsblock 2 weist zwei durch die Enden seiner U-Form gebildete Spannarme 8, lo auf, die durch eine Kopfschraube 12,eine an den Kopf 14 der Kopfschraube 12 anliegende. Ringfederanordnung 16 und eine Mutter 18 zusammengehalten sind, wobei der Kopf 14 und die Mutter 18 in Einsenkungen 20, 22 der Spannarme 8, 1o liegen. Die der Mutter 18 zug.eordnete Einsenkung 22 umschließt die Mutter 18 gegen Verdrehung.The brake block 2 has two formed by the ends of its U-shape Clamping arms 8, lo on, which by a head screw 12, one on the head 14 of the head screw 12 adjacent. Ring spring assembly 16 and a nut 18 are held together, wherein the head 14 and the nut 18 lie in depressions 20, 22 of the clamping arms 8, 1o. The recess 22 associated with the nut 18 encloses the nut 18 against rotation.

Der Kopf 14 weist bekannte Angriffsflächen 24 zur Verdrehung auf.The head 14 has known engagement surfaces 24 for rotation.

Die Ringfederanordnung ist durch zwei mit ihren Innenradien aneinanderstoßenden Kegelfedern 26, 28 gebildet. Zwischen der Kegelfeder 26 und dem Boden der Einsenkung 20 liegt eine Beilagscheibe 30.The ring spring arrangement is made up of two abutting one another with their inner radii Conical springs 26, 28 formed. Between the conical spring 26 and the bottom of the depression 20 is a washer 30.
