Description

Die Erfindung bezieht sich auf einen stufenloser, hilfskraftbetätigter Kraftwagentürfeststeller, bestehend aus einem am einen Türanordnungsteil, Tür oder Türsäule um eine zur Türscharnierachse parallele Achse schwenkbar angelenkten, starren Türhalteglied und einer diesem zugeordneten, am anderen Türanordnungsteil angeordneten Brems-bzw. Feststelleinrichtung sowie einer ansteuerbaren hilfskraftbeaufschlagten Einrichtung zum Betätigen der Brems-bzw. Feststelleinrichtung in Abhängigkeit einerseits vom aktuellen Türöffnungswinkel und andererseits von der momentanen Winkelgeschwindigkeit der Türe und den an der Türe angreifenden Öffnungs- bzw. Schließkräften sowie gegebenenfalls sonstigen Bezugsgrößen für die Beurteilung der Bewegungssituation der Türe, wobei die Brems-bzw. Feststelleinrichtung ein in Abhängigkeit von der Türbewegung rotierend, angetriebenes Teil und ein diesem zugeordnetes Brems-und Halteteil umfaßt.The invention relates to a stepless, auxiliary operated Motor vehicle door arrester, consisting of a door on a door arrangement part or door pillar can be pivoted about an axis parallel to the door hinge axis hinged, rigid door holding member and one associated with it, on the other Door arrangement part arranged braking or. Locking device and one controllable auxiliary device for actuating the brake or. Locking device depending on the one hand on the current Door opening angle and on the other hand from the current angular velocity the door and the opening and closing forces acting on the door and where appropriate, other reference values for the assessment of the Movement situation of the door, the braking or. Locking device an in Dependence on the door movement rotating, driven part and this one associated brake and holding part includes.

Allen bekannten Bauarten von mechanisch arbeitenden Türfeststellern für Kraftwagentüren ist gemeinsam, daß mit einem starren Türhalteglied, meist einer Türhaltestange zusammenwirkende Brems-bzw. Halteteile, insbesondere Bremsbacken oder Bremsrollen mit einer Federlast beaufschlagt sind und daher die aufbringbare Brems-bzw. Haltekraft nahezu ausschließlich von der Größe der Federbelastung der Brems-bzw. Halteteile abhängig ist. Daraus resultiert, daß sich stufenlose und vor allem eine gesteuerte Feststellung der Türe in beliebigen Öffnungslagen entweder gar nicht oder nur mit einem sehr hohen Aufwand realisieren läßt. Darüberhinaus ist ein stufenlos wirkender Tüfeststeller aus der EP-A-0 326 823 bekannt, der sich prinzipiell durch die Anwendung eines mit einer glattflächigen Türhaltestange zusammenwirkenden Klemmkörpers auszeichnet, wobei der Klemmkörper ausschließlich und selbsttätig durch eine Bewegungsumkehr der Türhaltestange in seine Wirkstellung verbracht wird. eine Ansteuerbarkeit in Abhängigkeit von der aktuellen Bewegungssituation der Türe läßt sich dabei naturgemäß nicht vorsehen.All known types of mechanically working door stops for Motor vehicle doors have in common that with a rigid door support member, usually one Door holding rod interacting brake or. Holding parts, in particular Brake shoes or brake rollers are loaded with a spring load and therefore the applied brake or. Holding force almost exclusively from the size of the Spring loading of the brake or. Holding parts is dependent. The result of this is that stepless and above all a controlled locking of the door in any Opening positions either not at all or only with a very high effort can be realized. In addition, a steplessly acting door stop is from the EP-A-0 326 823 known, which is principally the use of a with a features smooth-acting door holding rod interacting clamping body, the clamping body exclusively and automatically by a Reversal of movement of the door support rod is brought into its operative position. a Controllability depending on the current movement situation of the door can of course not be provided.

Für ansteuerbare Türfeststeller ist es aus der DE-A- 42 09 876 bekannt, daß ein in Abhängigkeit von der Türbewegung rotierend angetriebenes Teil durch eine vermittels einer mit einer Türhaltestange gekoppelte Spindel angetriebene Spindelmutter gebildet ist und eine auf diese wirkende Brems-bzw. Feststelleinrichtung durch eine mittels eines rotierend arbeitenden Elektromotores antreibbare Zangenbremse gebildet ist. Die Verwendung einer durch einen rotierend arbeitenden Elektromotor antreibbaren Zangenbremse führt dabei notwendigerweise zu einer großen Baulänge der gesamten Brems-bzw. Feststelleinrichtung, für deren Unterbringung in einem Türkörper meist kein ausreichender Raum zur Verfügung steht. Als Zangenbremse ist ferner auch die Brems-und Feststelleinrichtung des Türfeststellers nach der DE-A- 41 30 782 ausgebildet. Bei dem Türfeststeller nach der DE-A- 41 30 782 wirkt die Zangenbremse unmittelbar mit einer glattflächigen Türhaltestange zusammen, woraus naturgemäß ein verhältnismäßig schroffes Einsetzen der Bremskräfte und damit ein beträchtlich verminderter Komfort bei der Handhabung der Fahrzeugtüre resultiert. Zugleich ist es aus der DE-A- 41 30 782 auch bekannt die Brems-bzw. Halteteile wenigstens in Brems-bzw. Halterichtung direkt anzutreiben und lediglich dem Lösen der Brems-bzw. Haltewirkung eine Federkraft zuzuordnen. Angesichts der Größe der bei Kraftwagentürfeststellern erforderlichen Brems-und Haltekräfte sind dabei entsprechend starke Antriebe und demzufolge eine großvolumige Bauweise der Türfeststeller unumgänglich. Ferner zeichnen sich diese bekannten Bauarten von Türfeststellern auch noch durch eine schroff einsetzende Brems-bzw. Haltewirkung aus, was eine beträchtliche Verringerung des Betätigungskomforts der Fahrzeugtüre zur Folge hat. Eine solche großvolumige Bauweise der Türfeststeller läßt sich, zumindest bei den bisher bekannt gewordenen Bauarten von ansteuerbaren Türfeststellern auch nicht durch die Anwendung einer Übersetzung verhindern, ganz abgesehen davon, daß eine solche Maßnahme zu einem erheblichen technischen und wirtschaftlichen Aufwand führt. Im Übrigen sind alle bekannten Bauarten von ansteuerbaren Türfeststellern zudem noch mit dem Nachteil eines verhältnismäßig hohen Gewichtes behaftet.For controllable door locks, it is known from DE-A-42 09 876 that an in Dependence on the door movement of a rotating driven part driven by a spindle coupled to a door support rod Spindle nut is formed and a braking or acting on it. Locking device by means of a rotating electric motor drivable caliper brake is formed. The use of one by one rotatable electric brake caliper brake leads necessarily to a large overall length of the entire braking or. Locking device, usually for the accommodation in a door body sufficient space is available. As a caliper brake is also the Braking and locking device of the door arrester according to DE-A-41 30 782 educated. In the door lock according to DE-A-41 30 782, the Caliper brake immediately together with a smooth door support bar, which naturally results in a relatively abrupt application of the braking forces and thus a considerably reduced comfort when handling the Vehicle door results. At the same time, it is also known from DE-A-41 30 782 Braking or Holding parts at least in braking or. Drive direction to drive directly and only releasing the brake or. Holding force a spring force assign. Given the size of those required by motor vehicle door locks Braking and holding forces are accordingly strong drives and consequently a large-volume construction of the door lock is essential. Also stand out these known types of door locks also by a rugged braking or Holding effect out, which is a significant reduction the operating comfort of the vehicle door. Such a large volume Construction of the door stay can be, at least in the previously known types of controllable door stops also not by the Prevent application of a translation, quite apart from that Measure leads to a considerable technical and economic effort. Incidentally, all known types of controllable door stops are also has the disadvantage of a relatively high weight.

Der Erfindung liegt daher die Aufgabe zugrunde einen hilfskraftbetätigten, steuerbaren Türfeststeller der eingangs genannten Bauart dahingehend zu verbessern, daß er bei ausreichend hoher Brems-und Haltekraft und kleinbauender Bauweise feinfühlig ansteuerbar und zum einen mit einer geringstmöglichen Anzahl zudem einfacher Bauteile herstellbar ist und zugleich auch ein geringes Eigengewicht besitzt.The invention is therefore based on the object of an auxiliary power-operated, controllable door arrester of the type mentioned above improve that he has sufficient braking and holding power and small Construction can be controlled sensitively and on the one hand with the lowest possible Number of simple components can also be produced and at the same time a small number Own weight.

Diese Aufgabe wird erfindungsgemäß im Wesentlichen dadurch gelöst, daß dem rotierend, angetriebenen Teil der Brems-bzw. Feststelleinrichtung ein mit diesem zusammenwirkendes, antreibbares und nach Art einer Bandbremse ausgebildetes Brems-und Halteteil zugeordnet ist, welches vermittels zumindest eines hilfskraftbeaufschlagten Antriebselementes wenigstens in Richtung auf ihre Wirkstellung bewegbar ist.This object is essentially achieved in that the rotating, driven part of the brake or. Locking device one with this interacting, drivable and designed in the manner of a band brake Brake and holding part is assigned, which by means of at least one assisted drive element at least in the direction of their Active position is movable.

Diese erfindungsgemäße Gestaltung der Brems-und Halteeinrichtung eines Kraftwagentürfeststellers ermöglicht neben einer verhältnismäßig kleinbauenden Gestaltung des Türfeststellers auch eine feinfühlige Ansteuerbarkeit, d.h. ein feinfühliges ruckfreies Einsetzen der Brems-bzw. Haltekraft. Dabei ist dem Konstrukteur zugleich auch eine weitgehende Gestaltungsfreiheit hinsichtlich der Auslegung von Antriebs-und Antriebsübertragungselement belassen, so daß er durch entsprechende Gestaltung und Auslegung von Antriebs-und Antriebsübertragungselement einerseits und Brems-bzw. Halteteil andererseits ohne die Gefahr einer gegenseitigen nachteiligen Beeinflußung auch bei hohen aufzzubringenden Brems-und Haltekräften sowohl die Feinfühligkeit des Einsetzens der Brems-bzw. Haltewirkung als auch die Bauform des Türfeststellers den jeweils vorgegebenen Verhältnissen optimal entsprechend auslegen kann. Zudem eröffnet sich die Möglichkeit hand in hand mit einer weitgehenden Verringerung der erforderlichen Einzelteile auch das Gesamtgewicht des Türfeststellers erheblich zu verringern. Dabei kann das in Abhängigkeit von der Türbewegung angetriebene Teil naturgemäß auch ein linear angetriebenes Teil sein, sofern dies eine einfachere Anpassung des Türfeststellers an die vorgegebenen Einbauverhältnisse verspricht.
Ein ganz besonderer Vorteil der erfindungsgemäßen Gestaltung eines Türfeststellers liegt ferner darin, daß bei geeigneter Auslegung ohne jeden zusätzlichen Aufwand, d.h. ohne zusätzliche Teile, den beiden Bewegungsrichtungen der Türe unterschiedlich große Bremskräfte zugeordnet werden können.This inventive design of the braking and holding device of a motor vehicle door lock enables not only a relatively small design of the door lock but also sensitive controllability, ie a sensitive, jerk-free application of the brake or. Holding force. At the same time, the designer is also given extensive freedom of design with regard to the design of the drive and drive transmission element, so that on the one hand he has the appropriate design and design of the drive and drive transmission element and the braking or. Holding part, on the other hand, without the risk of mutual adverse influence, even with high braking and holding forces to be applied, both the sensitivity of the application of the braking or. Holding effect as well as the design of the door arrester can be optimally designed according to the given conditions. In addition, there is the possibility of significantly reducing the overall weight of the door arrester, hand in hand with a substantial reduction in the number of individual parts required. The part driven depending on the door movement can of course also be a linearly driven part, provided that this promises a simpler adaptation of the door arrester to the given installation conditions.
A very special advantage of the design of a door arrester according to the invention is further that with a suitable design, braking forces of different magnitudes can be assigned to the two directions of movement of the door without any additional effort, ie without additional parts.

In einer vorzugsweisen Verwirklichungfsform der Erfindung ist vorgesehen, daß das Brems-bzw. Halteteil durch einen Längenabschnitt eines Seiles oder Bandes bzw. ein durch ein solches beaufschlagbares Bremsglied gebildet ist, wobei das Seil bzw. das Band beidendig mit einem durch einen Schwenkhebel gebildeten Antriebselement verbunden ist und wobei das Bremsband bzw. Bremsseil der Brems- bzw. Feststelleinrichtung am Außenumfang eines in Abhängigkeit von der Türschwenkbewegung rotierend angetriebenen, vorzugsweise walzenförmigen Teiles anliegt sowie mittels eines Schwenkhebels in Anzugsrichtung verstellbar ist.In a preferred embodiment of the invention it is provided that the braking or Holding part by a length section of a rope or band or a braking member which can be acted upon, the rope or the band at both ends with a pivot lever Drive element is connected and wherein the brake band or brake cable Braking or locking device on the outer circumference depending on the Door pivoting motion driven, preferably roller-shaped Part rests and is adjustable in the tightening direction by means of a pivot lever.

Das in Abhängigkeit von der Türbewegung rotierend angetriebene Teil der Brems-bzw. Feststelleinrichtung steht zweckmäßigerweise mittel-oder unmittelbar im kämmenden Eingriff mit dem starren Türhalteglied steht. wobei eine besonders zweckmäßige aber nicht ausschließliche Ausgestaltungsmöglichkeit darin gesehen wird, daß das starre Türhalteglied durch eine Gewindespindel und das in Abhängigkeit von der Türbewegung rotierend angetriebene Teil der Brems- bzw. Feststelleinrichtung durch eine in einem feststehenden Gehäuse drehbar gelagerte Spindelmutter gebildet ist. The part of the braking or. The locking device is expediently located directly or indirectly in the intermeshing engagement with the rigid door holding member. being a special one Appropriate but not exclusive design option seen therein is that the rigid door support member by a threaded spindle and in Depending on the door movement, the rotating part of the braking or Locking device by a rotatably mounted in a fixed housing Spindle nut is formed.

Diese Ausgestaltung eröffnet dem Konstrukteur eine große Variationsmöglichkeit hinsichtlich der aufbringbaren Bremsund Haltekräfte dadurch, daß entweder der Steigungswinkel der Gewindespindel größer gewählt ist als der Reibwinkel zwischen Spindel und Spindelmuter zuzüglich der Reibung in den ihr zugeordneten Axiallagern oder daß der Steigungswinkel der Gewindespindel gleichgroß gewählt ist als der Reibwinkel zwischen Spindel und Spindelmuter zuzüglich der Reibung in den ihr zugeordneten Axiallagern.This configuration opens up a wide range of variations for the designer With regard to the braking and holding forces that can be applied, either Pitch angle of the threaded spindle is chosen larger than the friction angle between spindle and spindle nut plus the friction in the assigned to it Thrust bearings or that the pitch angle of the threaded spindle is chosen to be the same size is the friction angle between the spindle and spindle nut plus the friction in the associated axial bearings.

In weiterer Ausgestaltung ist ferner vorgesehen, daß einem auf das Brems-bzw. Halteteil wirkenden, dreh-oder schwenkbaren Antriebselement anstelle eines manuellen Antriebes ein in Abhängigkeit einerseits vom aktuellen Türöffnungswinkel und andererseits von der momentanen Winkelgeschwindigkeit der Türe und den an der Türe angreifenden Öffnungsbzw. Schließkräften ansteuerbarer motorischer Antrieb zugeordnet ist.In a further embodiment it is further provided that one on the braking or. Holding part acting, rotatable or pivotable drive element instead of one manual drive depending on the one hand on the current Door opening angle and on the other hand from the current angular velocity the door and the opening or. Closing forces controllable motor drive is assigned.

Der motorische Antrieb für den das Antriebselement bildenden Schwenkhebel kann dabei als rotierend arbeitender Schrittschaltmotor ausgebildet sein und mit dem einen Ende des das Antriebselement bildenden Schwenkhebels vermittels eines Nockens oder Excenters zusammenwirken.The motor drive for the swivel lever forming the drive element can be designed as a rotating stepper motor and with the an end of the pivoting lever forming the drive element of a cam or eccentric.

Es kann aber ebenso vorgesehen sein, daß der motorische, insbesondere elektromotorische Antrieb als Linearmotor ausgebildet ist und mit dem einen Ende des das Antriebelement bildenden Schwenkhebels direkt zusammenwirkt.However, it can also be provided that the motorized in particular, electromotive drive designed as a linear motor is and with one end of the drive element forming pivot lever cooperates directly.

Hinsichtlich der Anordnung des Brems-bzw. Halteteiles der Feststelleinrichtung ist vorgesehen, daß das durch einen Längenabschnitt eines Seiles oder Bandes gebildete Brems-bzw. Halteteil das rotierend angetriebene Teil der Brems-bzw. Halteeinrichtung mittels wenigstens einer Umschlingung übergreift. Das Seil kann hierbei durch ein Drahtmaterial gebildet sein, wobei je nach den Reibbeiwerten von Draht bzw. Seil einerseits und rotierend angetriebenem Teil der Brems- bzw. Feststelleinrichtung andererseits eine oder zwei Umschlinungen des rotierend angetriebenen Teiles vorgesehen sein können. Für höhere Brems-bzw. Haltekräfte kann sich auch die Verwendung eines Bandes anstelle eines Seiles oder Drahtes als Brems-bzw. Halteteil empfehlen.With regard to the arrangement of the brake or. Holding part of the Locking device is provided that by a Longitudinal section of a rope or band formed braking or. Holding part the rotatingly driven part of the brake or. Holding device by means of at least one loop spreads. The rope can be made of a wire material be formed, depending on the coefficient of friction of wire or rope on the one hand and rotatingly driven part of the Braking or locking device on the other hand one or two wrapping around the rotating driven part can be provided. For higher braking or. Holding forces can also use a tape instead of a Rope or wire as braking or. Recommend holding part.

In einer wweiteren Ausgestaltungsmöglichkeit ist weiter vorgesehen, daß der das Antriebsübertragungsglied bildende Schwenkhebel in einer Richtung, vorzugsweise in seiner der der Einrückrichtung der Brems-bzw. Feststelleinrichtung zugeordneten Bewegungsrichtung ständig mit der Last einer Druckfeder beaufschlagt ist. Bei dieser Ausgestaltung ist die Brems-bzw. Feststelleinrichtung ständig eingerückt und die Brems-bzw. Feststelleinrichtung bei einem beabsichtigten Bewegen der Türe durch den manuellen oder motorischen Antrieb gelüftet, solange eine entsprechende Stellkraft an der Türe angreift. Vorteilhaft an dieser Gestaltungsvariante ist, daß der Antriebsmotor immer nur kurzzeitig, nämlich über die Zeit eines beabsichtigen Bewegens der Türe hin unter Last steht, die über die wesentlich längeren Stillstandszeiten hin aber unter der Wirkung der Federkraft festgestellt ist.In a further design option is further provided that the drive transmission member forming Swivel lever in one direction, preferably in its the the direction of engagement of the brake or. Locking device assigned Direction of movement constantly with the load of one Compression spring is applied. In this configuration is the braking or Locking device constantly engaged and the braking or Locking device for an intended Moving the door by manual or motor Actuator ventilated as long as a corresponding actuating force is on attacks the door. Advantage of this design variant is that the drive motor is only for a short time, namely over the time an intentional movement of the door underneath Load stands that over the much longer downtimes but under the action of the spring force is established.

In einer weiteren Abwandlung des erfindungsgemäßen Kraftwagentürfeststellers kann ferner auch vorgesehen sein, daß das wenigstens eine Brems-bzw. Halteteil als von einem Längenabschnitt eines Seiles oder Bandes übergriffener Bremsklotz oder Bremsbacke ausgebildet ist und mit dem Türhalteglied reibschlüssig zusammenwirkt.In a further modification of the motor vehicle door arrester according to the invention can also be provided that the at least one braking or Holding part as of a length section a brake block overlapped by a rope or band or brake shoe is formed and with the door holding member cooperates frictionally.

Weitere Einzelausgestaltungen ergeben sich auch noch daraus, daß der Schwenkhebel vermittels eines federbelasteten Stößels mit einem ihm zugeordneten Verstellnocken bzw. Verstellexcenter im bleibenden Kontakt steht und der Schwenkhebel um eine zur Spindel parallele Achse schwenkbar an einem die Spindelmutter lagernden Gehäuse angelenkt ist, wobei ferner dem Antrieb des Schwenkhebels ein von einem Elektromotor angetrieber Kurbelzapfen zugeordnet ist, welcher um eine zur Spindel parallele Achse rotiert und zugleich auch einen Teil dser Steuereinrichtung für den Türfeststeller bildende, den Festell-oder Freigabezustand des Türfeststellers anzeigende Mikroschalter betätigt.Further individual configurations also result from that the pivot lever by means of a spring-loaded Ram with an adjustment cam or adjustment eccentric assigned to it is in permanent contact and the swivel lever pivotable about an axis parallel to the spindle is hinged to a housing supporting the spindle nut, wherein also the drive of the pivot lever one of a Electric motor driven crank pin is assigned which rotates about an axis parallel to the spindle and at the same time also part of this control device for the door arrester forming, the mounting or release status of the Door switch indicating microswitch operated.

Der im Ausführungsbeispiel dargestellte Kraftwagentürfeststeller, besteht im Wesentlichen aus einem am einen Türanordnungsteil, Tür oder Türsäule um eine zur Türscharnierachse parallele Achse 1 schwenkbar angelenkten, starren und als Gewindespindel 2 ausgebildeten Türhalteglied und einer diesem zugeordneten, in einem am anderen Türanordnungsteil angeordneten Gehäuse 3 aufgenommenen Brems-bzw. Feststelleinrichtung sowie einer von einem ansteuerbaren Elektromotor 4 antreibbaren, durch einen Schwenkhebel 5 gebildeten Einrichtung zum Betätigen der Brems- bzw. Feststelleinrichtung in Abhängigkeit von durch nicht dargestellte Sensoren oder dergl erfassbaren Kriterien der Bewegungssituation der Türe. Die Brems-bzw. Feststelleinrichtung umfaßt eine über Axiallager 6 drehbar im Gehäuse 3 gelagerte Spindelmutter 7 und ein durch einen Längenabschnitt 8 eines Seiles gebildetes Brems-bzw. Halteteil sowie eine den Schwenkhebel 5 belastende Druckfeder 9. Der das Brems-bzw. Halteteil bildende Längenabschnitt eines Seiles 8 umschlingt die Spindelmutter 7 und ist mit seinen beiden Enden 10 und 11 an den Schwenkhebel 5 angeschlossen.The motor vehicle door arrester shown in the exemplary embodiment, consists essentially of a part of a door arrangement, Door or door pillar around one to the door hinge axis parallel axis 1 pivoted, rigid and designed as a threaded spindle 2 door holding member and one assigned to this, in one on the other door arrangement part arranged housing 3 recorded brake or. Locking device and one from a controllable electric motor 4 drivable, formed by a pivot lever 5 Device for actuating the braking or locking device depending on sensors not shown or similarly ascertainable criteria of the movement situation the door. The brake or. Locking device includes a spindle nut rotatably mounted in the housing 3 via axial bearings 6 7 and one by a length section 8 of a Rope formed braking or Holding part and a Swing lever 5 compressive spring 9. The brake or. Holding part forming length section of a rope 8 wraps around the spindle nut 7 and is with its two Ends 10 and 11 connected to the pivot lever 5.

Bei der in der Figur 3 dargestellten Ausführungsform ist der das Brems-bzw. Halteteil der Feststelleinrichtung bildende Längenabschnitt 8 eines Seiles mit seinen beiden Enden 10 und 11 in einem gemeinsamen Befestigungsteil 12 am Schwenkhebel 5 befestigt und der Schwenkhebel 5 seinerseits an seinem freien Ende 13 durch eine Druckfeder 9 beaufschlagt. Daraus resultiert, daß über den Längenabschnitt 8 des Seiles an der Spindelmutter 7 solange ein Bremsmoment ausgeübt wird bis der Schwenkhebel 5 vermittels des Elektromotors entgegen der Federlast in eine Lösestellung verschwenkt wird. Da hierbei die beiden Enden des Längenabschnittes 8 des Seiles in einem gemeinsamen Punkt 12 am Schwenkhebel 5 befestigt sind ist auch das auf die Spindelmutter ausgeübte Bremsmoment Md2 bzw. Md3 für beide Drehrichtungen der Spindelmutter 7 gleichgroß.In the embodiment shown in Figure 3 is the brake or. Holding part of the locking device forming Length section 8 of a rope with its two Ends 10 and 11 in a common fastening part 12 attached to the pivot lever 5 and the pivot lever 5 in turn at its free end 13 by a compression spring 9 acted upon. The result of this is that over the length section 8 of the rope on the spindle nut 7 as long Braking torque is exerted until the swivel lever 5 of the electric motor against the spring load in a release position is pivoted. Because here the two ends of the length section 8 of the rope in a common point 12 attached to the pivot lever 5 is also on the spindle nut applied braking torque Md2 or Md3 for both The directions of rotation of the spindle nut 7 are the same size.

Bei der in der Figur 4 dargestellten Ausführungsform ist der das Brems-bzw. Halteteil der Feststelleinrichtung bildende Längenabschnitt 8 eines Seiles mit seinem einen Ende 10 in einem ersten in der durch die Spindelachse verlaufenden vertikalen Ebene angeordneten Befestigungsteil 14 und mit seinem anderen Ende 11 in einem zweiten in einem Abstand zu der durch die Spindelachse verlaufenden vertikalen Ebene angeordneten Befestigungsteil 15 am Schwenkhebel 5 befestigt. Aus der an dessen freiem Ende 13 am Schwenkhebel angreifenden Federlast 9 resultiert daher, daß über den Längenabschnitt 8 des Seiles an der Spindelmutter 7 solange ein Bremsmoment ausgeübt wird bis der Schwenkhebel 5 vermittels des Elektromotors entgegen der Federlast 9 in eine Lösestellung verschwenkt wird, wobei infolge des Umstandes, daß die beiden Enden des Längenabschnittes 8 des Seiles mit unterschiedlichen Abständen zu der durch die Spindelachse verlaufenden vertikalen Ebene an den Schwenkhebel 5 angeschlossen sind, das auf die Spindelmutter ausgeübte Bremsmoment Md2 für die eine Drehrichtung der Spindelmutter größer ist als das Bremsmoment Md3 für die andere Drehrichtung der Spindelmutter 7.In the embodiment shown in Figure 4 is the brake or. Holding part of the locking device forming Length section 8 of a rope with one end 10 in a first in the extending through the spindle axis vertical plane arranged fastening part 14 and with its other end 11 at a second at a distance to the vertical through the spindle axis Fastening part 15 arranged level on the swivel lever 5 attached. From the free end 13 on the swivel lever Attacking spring load 9 results, therefore, in that Length section 8 of the rope on the spindle nut 7 as long a braking torque is exerted until the swivel lever 5 of the electric motor against the spring load 9 in a Release position is pivoted, due to the fact that the two ends of the length section 8 of the rope with different distances from that through the spindle axis extending vertical level connected to the pivot lever 5 are the braking torque exerted on the spindle nut Md2 for the one direction of rotation of the spindle nut is greater than the braking torque Md3 for the other direction of rotation the spindle nut 7.

Mit dem das Antriebselement bildenden Schwenkhebel 5 wirkt der Elektromotor 4 vermittels eines Nockens oder Excenters 16 zusammen, wobei ein Übertragungshebel 17 vermittels eines Federstößels 18 mit dem Nocken bzw. Excenter in Kontakt steht.Works with the pivot lever 5 forming the drive element the electric motor 4 by means of a cam or eccentric 16 together, with a transmission lever 17 a spring plunger 18 in contact with the cam or eccentric stands.
