Schließkräften sowie von gegebenenfalls sonstigen Bezugsgrößen für die Beurteilung der Bewegungssituation der Tür entsteht. Zudem erfordert die bekannte Bauart eine motorische Einrichtung zur Erzeugung einer zur Betätigung der Brems- bzw. Feststelleinrichtung hinreichenden Hilfskraft. Hieraus folgt ein erheblicher Herstellungsaufwand.DE-A-44 35 720 describes a controllable assistant Device for actuating a braking or locking device, from which a not inconsiderable effort initially for the design of a reasonably reliable and at the same time sufficiently sensitive working device for controlling the brake actuating Assistant depending on both the current door opening angle and also from the momentary angular velocity of the door and that at the Opening or closing forces attacking the door and, if necessary other reference values for the assessment of the movement situation of the Door is created.

Zur Ableitung einer Verstellbewegung für die die Feststellung der Tür bewirkenden Freilaufrollen aus der Türbewegung können dabei die unterschiedlichsten Mittel vorgesehen sein. Wesentlichster Vorteil ist von sonstigen Ausstattungen unabhängig, daß die Anwendung eines Freilaufs als Brems- und Feststellmittel die Aufbringung hoher Brems- und Feststellkräfte bei geringem baulichen und wirtschaftlichen Aufwand gewährleistet. The spindle nut, which is rotatably mounted in the brake housing, is by means of the Brake housing in a holder housing arranged on the door housed and depending on the movement situation of the door by means of a mechanical device, namely a freewheel, blockable. To derive an adjustment movement for the determination the freewheeling rollers causing the door from the door movement can various means can be provided. The main advantage is from other equipment regardless that the use of a freewheel as braking and locking means the application of high braking and Locking forces with little constructional and economic effort guaranteed.

This arrangement of the the braking and locking device forming freewheel in one with the Vehicle door connected bracket housing and the simultaneous connection enable the release device for the freewheel with the holder housing an immediate derivation of one for engaging and releasing the brake and Locking device suitable control force from the door movement. The Use only one that starts from the force attack on the door Release of the locking device, allows the waiver of a complex sensors or the like. and an equally complex Auxiliary power generation to bring about the required locking force.
Insbesondere kann ein kleiner Bruchteil der an der Tür zu deren gewellter Bewegung angreifenden Kraft in eine Antriebskraft zum Lösen der unter der Wirkung einer Federkraft in ihrer Haltestellung gehaltenen Brems- und Feststelleinrichtung umgewandelt werden. Da bei einer solchen Anordnung des Fahrzeugtür- bzw. Kraftwagentürfeststellers an der Tür zudem keine Kraftübertragungen außerhalb des Haltergehäuses benötigt werden, kann die Einrichtung aus verhältnismäßig wenigen und einfachen Teilen aufgebaut und insgesamt innerhalb des Haltergehäuses untergebracht werden, ohne daß dieses zu groß werdende Abmessungen aufzuweisen braucht.In particular, a small fraction of those on the door can be corrugated Moving force into a driving force to loosen the under the Effect of a spring force held in its stop position Locking device to be converted. Because with such an arrangement the vehicle door or motor vehicle door lock on the door also none Power transmissions outside the holder housing may be required the establishment of relatively few and simple parts constructed and housed overall within the holder housing without having this becoming too large needs.

Freilaufs 5 entsprechende Anzahl von Schaltfingern 17 aufweisender
Mitnehmerkäfig 18 zugeordnet, dessen Schaltfinger 17 über Schrägflächen
19 mit einer ihrerseits auf die Achsen 20 der Klemmrollen 15 des Freilaufs 5
wirkenden Ausrückscheibe 21 zusammenwirken, vgl. insbesondere Fig. 3
und 7.The
Die Klemmrollen 15 des Freilaufs 5 sind in Richtung auf ihre
Klemmstellung durch Federn 22 beaufschlagt, derart, daß der Freilauf 5 in
seine Sperrlage zurückkehrt, sobald die Ausrückkraft nachläßt bzw.
wegfällt. Dem Lösen der Sperrwirkung des Freilaufs 5 in
Türschließrichtung ist eine im Bereich des Außenringes 14 des Freilaufs 5
untergebrachte Kipphebelanordnung zugeordnet, welche um zur
Spindelachse parallele Achsen 23 schwenkbare Kipphebel 24 aufweist, die
ihrerseits mittels in Abhängigkeit von der Türschließbewegung
drehangetriebener Greifer 25 verstellbar sind, vgl. insbesondere Fig. 5. Die
Kipphebel 24 wirken dabei über ihren einen Hebelarm 26 mit dem Greifer
25 und über ihren anderen Hebelarm 27 mit den verlängerten Achsen 20 der
Klemmrollen 15 derart zusammen, daß die Klemmrollen 15 entgegen der
Wirkung der Federn 22 aus ihrer Klemmlage herausbewegt werden. Die
Greifer 25 sind mit einem ringförmigen Drehkörper 28 drehsicher
verbunden, welcher seinerseits vermittels einer als Rotationsdämpfer
wirkenden Visko-Kupplung 29 mit einer ihrerseits durch die Spindel 2
drehantreibbaren Steuermutter 30 gekoppelt ist.The
Das Haltergehäuse 3 ist vermittels eines Trägers 31 um eine senkrecht zur
Spindel 2 ausgerichtete Achse schwenkbar in zwei Lagerböcken 32
gelagert, wobei der Träger 31 über Lageraugen 33 zwischen die beiden
Lagerarme 34 der Lagerböcke 32 eingreift. Einerseits ist im übrigen die
Überlauflänge 35 der Spindel 2 mittels einer Hülse 36 abgeschirmt,
andererseits ist die Spindel 2 durch einen Faltenbalg 37 abgedeckt.The
Die Arbeitsweise des Türfeststellers besteht darin, daß zunächst beim
Öffnen der Tür das über die Spindelmutter 4 und den Freilauf 5 starr mit der
Spindel 2 verbundene Bremsgehäuse 6 gegen den Widerstand der gegen die
Stirnwand 10 des Haltergehäuses 3 abgestützten Druckfedern 9 solange
relativ zum Haltergehäuse 3 verschoben wird, bis die Schrägflächen 19 der
Schaltfinger 17 die Ausrückscheibe 21 soweit verdreht haben, daß die
Klemmrollen 15 des Freilaufs 5 aus ihrer Klemmlage heraus in eine
Lösestellung verstellt sind. Sobald die an der Spindel 2 als Zugkraft in
Erscheinung tretende Öffnungskraft zum gewollten Bewegen der Tür in
Öffnungsrichtung nachläßt bzw. aufhört wird das Bremsgehäuse 6 durch die
Druckfedern 9 wieder in seine Mittellage zurückbewegt, was zur Folge hat,
daß die Schrägflächen 19 der Schaltfinger 17 mit der Ausrückscheibe 21
außer Eingriff kommen und dadurch die Klemmrollen 15 des Freilaufs 5
durch ihre Einrückfedern 22 wieder in ihre Klemmstellung zurückbewegt
werden, so daß die Tür in der jeweiligen Momentanstellung blockiert bzw.
festgestellt ist. Beim Bewegen der Tür in Schließrichtung wird die
Steuermutter 30 durch die Spindel 2 relativ schnell rotierend
drehangetrieben. Die Rotationsbewegung der Steuermutter 30 wird
vermittels der als Rotationsdämpfer wirkenden Visko-Kupplung 29 in der
Weise auf den die Greifer 25 tragenden, ringförmigen Drehkörper 28
übertragen, daß die Greifer 25 eine sanft einsetzende und begrenzte
Bewegung um die Spindelachse bzw. die Freilaufachse ausführen und dabei
im Zusammenwirken mit deren Hebelarmen 26 die Kipphebel 24
umschalten derart, daß die Kipphebel 24 mit ihrem anderen Hebelarm 27
die Achsen 20 der Klemmrollen 15 soweit verstellen, daß die Klemmrollen
15 entgegen der Wirkung der Einrückfedern 22 des Freilaufs 5 aus Ihrer
Klemmstellung heraus bewegt werden und die Tür damit solange freigängig
bewegbar ist, als eine entsprechende, in Öffnungsrichtung gerichtete Kraft
auf sie ausgeübt wird. Bei einem Nachlassen oder Aufhören der in
Öffnungsrichtung der Tür gerichteten Kraft hört der Rotationsantrieb der
Steuermutter 30 auf und somit bricht die auf die Greifer 25 wirkende
Stellkraft zusammen, so daß die diesen zugeordneten Federn 22 die
Klemmrollen wieder in ihre Klemmlage 15 können und die Tür damit
wieder in ihrer jeweils aktuellen Lage blockiert bzw. festgestellt ist.The way the door arrester works is that first at
