Description
Die Erfindung betrifft eine Kraftfahrzeugtür, insbesondere grifflose Kraftfahrzeug-Seitentür, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a motor vehicle door, in particular a handleless motor vehicle side door, according to the preamble of claim 1.
Die wenigstens spaltweise Öffnung von Türflügeln bei Kraftfahrzeugtüren erfolgt regelmäßig, um die vollständige Öffnung der betreffenden Kraftfahrzeugtür zu erleichtern. Insbesondere bei grifflosen Kraftfahrzeugtüren kann auf diese Weise ein Bediener den durch die spaltweise Öffnung des Türflügels gebildeten Spalt zwischen der Kraftfahrzeugkarosserie und dem Türflügel nutzen, um den Türflügel zu hintergreifen und vollständig manuell aufzuschwenken. Zu diesem Zweck beschreibt
Die Lehre nach der
Der Innenhebel ist entgegen dem Uhrzeigersinn und der Außenhebel im Uhrzeigersinn aktiv rückschwenkend ausgebildet. Auf diese Weise wird ein Aussteller zur Verfügung gestellt, der auch ein sofortiges Wiederzuschlagen der zugehörigen Kraftfahrzeugtür unbeschadet übersteht. Das hat sich bewährt, ist jedoch im Hinblick auf den hierfür notwendigen konstruktiven Aufwand verbesserungsbedürftig.The inner lever is designed to pivot backwards in an anti-clockwise direction and the outer lever in a clockwise direction. In this way, an exhibitor is made available who can survive an immediate slamming of the associated motor vehicle door again without damage. This has proven itself, but is in need of improvement with regard to the design effort required for this.
In
Der Stand der Technik hat sich grundsätzlich bewährt. Allerdings sind die bisher verfolgten Lösungen überwiegend konstruktiv aufwendig gestaltet. Das stand bisher einer flächendeckenden Verwendung im Wege. Eine solche ist jedoch vor dem Hintergrund des zunehmenden Einsatzes sogenannter Türschlösser mit EÖ-Öffnungsfunktion (elektrisch öffnen) wünschenswert.The state of the art has basically proven itself. However, the solutions that have been pursued so far are predominantly designed in a constructively complex manner. So far, this has stood in the way of widespread use. However, against the background of the increasing use of so-called door locks with EÖ opening function (open electrically), this is desirable.
Denn bei Kraftfahrzeugtüren mit den angesprochenen EÖ-Türschlössern besteht oftmals das Problem, dass nach dem elektrischen Öffnen des fraglichen Kraftfahrzeugtürschlosses der sich zwangsläufig einstellende Spalt zwischen dem Türflügel und der Kraftfahrzeugkarosserie nicht ausreicht, damit ein Bediener einwandfrei den Türflügel hintergreifen und öffnen kann. Dieses Phänomen beobachtet man insbesondere dann, wenn die üblicherweise für die spaltweise Öffnung des Türflügels in diesem Zusammenhang verantwortlich zeichnenden Gummidichtungen in ihrem aufgebauten Dichtungsdruck nachlassen. Außerdem können etwaige Fertigungstoleranzen beim Anbau des Türflügels an die Kraftfahrzeugkarosserie dazu führen, dass prinzipbedingt der sich auf diese Weise einstellende Öffnungsspalt von seiner Größe her grundsätzlich nicht ausreicht. Hier will die Erfindung insgesamt Abhilfe schaffen.Because with motor vehicle doors with the mentioned EÖ door locks there is often the problem that after the electrical opening of the motor vehicle door lock in question, the gap that is inevitably established between the door leaf and the vehicle body is not sufficient for an operator to be able to reach behind the door leaf and open it properly. This phenomenon is observed in particular when the rubber seals, which are usually responsible for the gap-wise opening of the door leaf in this context, decrease in their sealing pressure. In addition, any manufacturing tolerances when mounting the door leaf on the motor vehicle body can lead to the fact that the size of the opening gap that is established in this way is fundamentally insufficient. The invention aims to provide a remedy here overall.
Der Erfindung liegt das technische Problem zugrunde, eine derartige Kraftfahrzeugtür so weiter zu entwickeln, dass ein sichere Öffnung des Türflügels gegenüber der Kraftfahrzeugkarosserie unter Berücksichtigung eines für die weitere Handhabung ausreichenden Spaltes mit konstruktiv einfachen Mitteln zur Verfügung gestellt wird.The invention is based on the technical problem of further developing such a motor vehicle door in such a way that a safe opening of the door leaf relative to the motor vehicle body is made available with structurally simple means, taking into account a gap sufficient for further handling.
Die Erfindung schlägt den Gegenstand des Anspruchs 1 vor. Vorteilhafte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen beschrieben.The invention proposes the subject matter of claim 1. Advantageous embodiments of the invention are described in the dependent claims.
Die Erfindung schlägt eine Kraftfahrzeugtür, insbesondere eine grifflose Kraftfahrzeug-Seitentür, vor mit einem Türflügel, zumindest einem Antrieb, und einem an den Antrieb angeschlossenen Ausstellglied zur zumindest spaltweisen Öffnung des Türflügels gegenüber einer Kraftfahrzeugkarosserie, wobei das an den Antrieb angeschlossene Ausstellglied als achsnah im Vergleich zu einer Drehachse des Türflügels angeordnetes Linearstellglied ausgebildet ist; wobei das Ausstellglied in ausgefahrener Position gegen die Kraftfahrzeugkarosserie fährt und dadurch den Türflügel wenigstens spaltweise öffnet; und wobei das Ausstellglied in eingefahrener Position nicht an der Kraftfahrzeugkarosserie anliegt.The invention proposes a motor vehicle door, in particular a handleless motor vehicle side door, with a door leaf, at least one drive, and a push-out member connected to the drive for at least a gap opening of the door leaf with respect to a motor vehicle body, the push-out member connected to the drive being close to the axis in comparison a linear actuator arranged to an axis of rotation of the door leaf is formed; wherein the deployment member moves in the extended position against the motor vehicle body and thereby opens the door leaf at least in gaps; and wherein the deployment member does not bear against the motor vehicle body in the retracted position.
Dabei hat es sich bewährt, wenn das Ausstellglied mit Hilfe des Antriebes überwiegend parallel zur Längserstreckung des Türflügels verstellt wird. Außerdem ist das Ausstellglied im Innern des Türflügels angeordnet, also in Richtung auf einen Innenraum der Kraftfahrzeugkarosserie hinweisend.It has proven to be useful if the actuating element is adjusted predominantly parallel to the longitudinal extension of the door leaf with the aid of the drive. In addition, the opening member is arranged in the interior of the door leaf, that is, pointing in the direction of an interior of the motor vehicle body.
Tatsächlich hat es sich bewährt, wenn das Ausstellglied in diesem Zusammenhang gegen eine Wand der Kraftfahrzeugkarosserie fährt, und zwar jenseits der Drehachse des Türflügels, d. h. in Verlängerung des Türflügels über die Drehachse hinaus. Die genannte Wand der Kraftfahrzeugkarosserie ist dabei überwiegend senkrecht zur Längserstreckung des Türflügels angeordnet bzw. verläuft überwiegend senkrecht zur Längserstreckung des betreffenden Türflügels. Eine derartige Wand ist typischerweise im Bereich einer Öffnung der Kraftfahrzeugkarosserie vorgesehen, welche mit Hilfe der erfindungsgemäßen Kraftfahrzeugtür verschlossen wird. Denn die fragliche Öffnung in der Kraftfahrzeugkarosserie ist regelmäßig mit der betreffenden und nach innen eingezogenen sowie umlaufenden Wand ausgerüstet, die typischerweise zur Anbringung einer Türgummidichtung, Festlegung eines Schließbolzens bzw. Schlosshalters und zur Befestigung von die Drehachse des Türflügels definierenden Scharnieren dient.In fact, it has proven to be useful if the opening element moves against a wall of the motor vehicle body in this context, namely beyond the axis of rotation of the door leaf, ie as an extension of the door leaf beyond the axis of rotation. The named wall of the motor vehicle body is arranged predominantly perpendicular to the longitudinal extent of the door leaf or runs predominantly perpendicular to the longitudinal extent of the relevant door leaf. Such a wall is typically provided in the area of an opening in the motor vehicle body which is closed with the aid of the motor vehicle door according to the invention. Because the opening in question in the motor vehicle body is regularly equipped with the relevant and inwardly drawn in and circumferential wall, which is typically used for attaching a rubber door seal, fixing a locking bolt or lock holder and for fastening the axis of rotation of the door leaf defining hinges.
Der Schließbolzen bzw. Schlosshalter wechselwirkt seinerseits mit einem Gesperre eines Kraftfahrzeugtürschlosses. Das Kraftfahrzeugtürschloss ist dabei regelmäßig innenseitig am Türflügel angebracht, so dass beim Schließen des Türflügels der Schließbolzen in das Gesperre einfährt und den Türflügel und damit die Kraftfahrzeugtür festhält.The locking bolt or lock holder in turn interacts with a locking mechanism of a motor vehicle door lock. The motor vehicle door lock is regularly attached to the inside of the door leaf, so that when the door leaf is closed, the locking bolt moves into the locking mechanism and holds the door leaf and thus the motor vehicle door in place.
Sobald nun das Gesperre geöffnet wird, sorgt der erfindungsgemäß vorgesehene Antrieb in Verbindung mit dem an den Antrieb angeschlossenen Ausstellglied dafür, dass der Türflügel zumindest spaltweise gegenüber der Kraftfahrzeugkarosserie geöffnet wird. Hierunter ist im Rahmen der Erfindung ein Spalt zwischen dem betreffenden Türflügel und der Kraftfahrzeugkarosserie gemeint, welcher eine Größenordnung von in etwa 50 mm bis 100 mm aufweist, so dass ein Bediener problemlos mit seiner Hand den Türflügel hintergreifen und vollständig öffnen kann.As soon as the locking mechanism is opened, the drive provided according to the invention, in conjunction with the opening element connected to the drive, ensures that the door leaf is opened at least in a gap with respect to the motor vehicle body. In the context of the invention, this means a gap between the relevant door leaf and the motor vehicle body, which has a size of around 50 mm to 100 mm, so that an operator can easily reach behind the door leaf with his hand and open it completely.
Dabei reichen in der Regel geringfügige Stellbewegungen des Ausstellgliedes aus, um die zuvor beschriebene spaltweise Öffnung unter Berücksichtigung eines Spaltes von in etwa 50 mm bis 100 mm zu realisieren. Tatsächlich haben sich an dieser Stelle Stellwege des Ausstellgliedes von beispielsweise 10 mm bis 20 mm als ausreichend erwiesen. Das lässt sich im Kern darauf zurückführen, dass das Ausstellglied zunächst einmal achsnah im Vergleich zu der Drehachse des Türflügels angeordnet ist. Da der Spalt demgegenüber am achsfernen Ende des Türflügels gemessen wird, dort wo üblicherweise auch das Kraftfahrzeugtürschloss an den Türflügel angeschlossen ist, führen selbst geringe achsnahe Stellwege jenseits der Drehfalle dazu, dass der Türflügel am achsfernen Ende eine signifikante Stellbewegung aufgrund der Hebelwirkung vollführt.As a rule, slight adjusting movements of the opening element are sufficient to realize the gap-wise opening described above, taking into account a gap of approximately 50 mm to 100 mm. In fact, travel of the actuating member of, for example, 10 mm to 20 mm has proven to be sufficient at this point. This can essentially be traced back to the fact that the opening element is initially arranged close to the axis in comparison to the axis of rotation of the door leaf. Since the gap, on the other hand, is measured at the end of the door leaf remote from the axis, where the motor vehicle door lock is usually also connected to the door leaf, even small adjustment paths near the axis beyond the rotary latch mean that the door leaf at the end remote from the axis performs a significant positioning movement due to the lever effect.
Aus diesem Grund kann das Ausstellglied vorteilhaft als Ausstellstößel ausgebildet sein, der den zuvor beschriebenen Stellweg von beispielsweise 10 mm bis 20 mm unschwer absolviert. Zu diesem Zweck ist das Ausstellglied vorteilhaft mit einer Stellstange ausgerüstet. Die Stellstange kann von einer Stellmutter des Antriebes zur Linearverstellung beaufschlagt werden.For this reason, the deployment member can advantageously be designed as a deployment ram which easily covers the previously described travel range of, for example, 10 mm to 20 mm. For this purpose, the opening element is advantageously equipped with an adjusting rod. The control rod can be of a Adjustment nut of the drive for linear adjustment are acted upon.
Das heißt, mit Hilfe der Stellmutter des Antriebes wird die Stellstange linear verstellt. Dazu ist es lediglich erforderlich, dass die Stellmutter in Rotationen versetzt wird. Diese Rotationen der Stellmutter führen dazu, dass die mit der Stellmutter kämmende Stellstange entsprechend ein- oder ausgefahren wird. Dadurch lässt sich die Linearverstellung des Ausstellstößels bzw. des Ausstellgliedes unschwer realisieren.This means that the adjusting rod is adjusted linearly with the aid of the adjusting nut of the actuator. For this it is only necessary that the adjusting nut is set in rotation. These rotations of the adjusting nut cause the adjusting rod meshing with the adjusting nut to be extended or retracted accordingly. As a result, the linear adjustment of the deployment ram or of the deployment element can be easily implemented.
Wie bereits erläutert, verfügt der Türflügel zusätzlich über ein innenseitig angeordnetes Kraftfahrzeugtürschloss. Bei diesem Kraftfahrzeugtürschloss kann es sich um ein mechanisches Kraftfahrzeugtürschloss handeln, also ein solches, bei dem das obligatorische Gesperre auf mechanischem Wege beispielsweise über einen Türgriff und angeschlossene Verbindungselemente geöffnet wird. Nach besonders bevorzugter Ausführungsform ist das fragliche Kraftfahrzeugtürschloss jedoch mit einem zugehörigen Schlossantrieb ausgerüstet und folglich als elektrisches Kraftfahrzeugtürschloss bzw. Elektroschloss ausgebildet.As already explained, the door leaf also has a motor vehicle door lock arranged on the inside. This motor vehicle door lock can be a mechanical motor vehicle door lock, that is to say one in which the obligatory locking mechanism is opened mechanically, for example via a door handle and connected connecting elements. According to a particularly preferred embodiment, however, the motor vehicle door lock in question is equipped with an associated lock drive and is consequently designed as an electric motor vehicle door lock or electric lock.
Bei dem Schlossantrieb handelt es sich im Allgemeinen um einen Öffnungsantrieb für das Gesperre. Grundsätzlich kann es sich bei dem Schlossantrieb aber auch um einen Antrieb beispielsweise zur Entriegelung des Kraftfahrzeugtürschlosses handeln. Im Falle des auf das Gesperre arbeitenden Schlossantriebes lässt sich das Kraftfahrzeugtürschloss elektrisch öffnen. Das heißt, der Schlossantrieb arbeitet in diesem Fall regelmäßig auf eine Sperrklinke des Gesperres aus Drehfalle und Sperrklinke.The lock drive is generally an opening drive for the locking mechanism. In principle, however, the lock drive can also be a drive, for example, for unlocking the motor vehicle door lock. In the case of the lock drive working on the locking mechanism, the motor vehicle door lock can be opened electrically. This means that in this case the lock drive regularly works on a pawl of the locking mechanism consisting of the rotary latch and pawl.
Sobald der Schlossantrieb die Sperrklinke von der Drehfalle abhebt, kann die Drehfalle federunterstützt öffnen. Zugleich wird der zuvor von der Drehfalle gefangene Schließbolzen freigegeben. Als Folge hiervon ist dann auch der Türflügel und mit ihm die gesamte Kraftfahrzeugtür frei und kann durch den von der Türgummidichtung aufgebauten Dichtungsdruck geringfügig ausgestellt werden. Sobald das Gesperre im Kraftfahrzeugtürschloss geöffnet ist, sorgt erfindungsgemäß der Antrieb für das Ausstellglied dafür, dass im Anschluss hieran der Türflügel mit Hilfe des Ausstellgliedes zumindest spaltweise geöffnet wird.As soon as the lock drive lifts the pawl off the rotary latch, the rotary latch can open with the assistance of a spring. At the same time, the locking bolt previously caught by the rotary latch is released. As a result of this, the door leaf and with it the entire motor vehicle door is free and can be accessed by the the seal pressure built up in the door rubber seal can be exhibited slightly. As soon as the locking mechanism in the motor vehicle door lock is opened, according to the invention the drive for the opening element ensures that the door leaf is subsequently opened with the aid of the opening element, at least in gaps.
Dazu ist regelmäßig eine Steuereinheit vorgesehen, welche den Antrieb für das Ausstellglied erst dann beaufschlagt, wenn das fragliche Gesperre im Kraftfahrzeugtürschloss geöffnet ist. Dazu mag dem Gesperre ein Sensor zugeordnet sein, welcher von der Steuereinheit abgefragt wird. Meldet der Sensor die Öffnung des Gesperres, so wird der Antrieb für das Ausstellglied beaufschlagt, um den Türflügel zumindest spaltweise zu öffnen.For this purpose, a control unit is regularly provided which only acts on the drive for the opening element when the lock in question in the motor vehicle door lock is opened. For this purpose, the locking mechanism may be assigned a sensor that is queried by the control unit. If the sensor reports the opening of the locking mechanism, the drive for the opening element is acted upon in order to open the door leaf at least in gaps.
Im Rahmen einer besonders bevorzugten Ausführungsform der Erfindung fungiert der zuvor bereits angesprochene Schlossantrieb des Kraftfahrzeugtürschlosses zugleich auch als Antrieb für das Ausstellglied. In diesem Zusammenhang mag der Schlossantrieb mittels eines Übertragungselementes auf das Ausstellglied arbeiten. Bei diesem Übertragungselement kann es sich um einen Bowdenzug handeln. Diese Vorgehensweise ist besonders einfach gestaltet, weil lediglich ein einziger Antrieb für einerseits das elektrische Öffnen des Gesperres und damit des Kraftfahrzeugtürschlosses im Ganzen und andererseits das Ausstellen des Türflügels genutzt wird. Diese gleichsam doppelte Funktionalität des Schlossantriebes berücksichtigt, dass das elektrische Öffnen und das Ausstellen sukzessive und nacheinander erfolgen, so dass auf einen (einzigen) Antrieb für beide Vorgehensweisen zurückgegriffen werden kann.In the context of a particularly preferred embodiment of the invention, the previously mentioned lock drive of the motor vehicle door lock also functions as a drive for the opening member. In this context, the lock drive may work on the actuating member by means of a transmission element. This transmission element can be a Bowden cable. This procedure is particularly simple because only a single drive is used for the electrical opening of the locking mechanism and thus the motor vehicle door lock as a whole, and for opening the door leaf. This, as it were, double functionality of the lock drive takes into account that the electrical opening and opening take place successively and one after the other, so that one (single) drive can be used for both procedures.
Darüber hinaus ist es selbstverständlich alternativ oder auch zusätzlich möglich, dass einerseits der Antrieb für das Ausstellglied realisiert wird und andererseits der Schlossantrieb für das Kraftfahrzeugtürschloss, welcher im Regelfall als Öffnungsantrieb für das Gesperre ausgebildet ist. In jedem Fall arbeitet die Erfindung mit nur wenigen Konstruktionselementen, was den technologischen Aufwand und die Kosten verringert. Außerdem wird die Funktionssicherheit gesteigert.In addition, it is of course alternatively or additionally possible that on the one hand the drive for the opening element is implemented and on the other hand the lock drive for the motor vehicle door lock, which is usually designed as an opening drive for the locking mechanism. In any case, the invention works with only a few design elements, what the technological Effort and costs are reduced. In addition, the functional reliability is increased.
Dabei macht im Kern die Erfindung von der Tatsache Gebrauch, dass die spaltweise Öffnung des Türflügels am fernen Ende des Türflügels im Vergleich zu dessen Drehachse zur Verfügung gestellt werden muss. Diese Bewegung am fernen Hebelarm lässt sich durch eine viel geringere Stellbewegung am nahen Hebelarm bzw. achsnah im Vergleich zu der Drehachse initiieren. Dadurch reicht es aus, wenn das Ausstellglied als Ausstellstößel ausgebildet ist und im Rahmen der beschriebenen Linearverstellung einen Stellweg von beispielsweise 10 mm bis 20 mm vollführt.In this case, the invention essentially makes use of the fact that the gap-wise opening of the door leaf must be made available at the far end of the door leaf compared to its axis of rotation. This movement on the remote lever arm can be initiated by a much smaller adjusting movement on the nearby lever arm or close to the axis compared to the axis of rotation. As a result, it is sufficient if the opening element is designed as an opening ram and, within the scope of the linear adjustment described, performs an adjustment path of, for example, 10 mm to 20 mm.
Der Antrieb und auch das Ausstellglied sind vorteilhaft im Innern des Türflügels angebracht. Grundsätzlich könnte das Ausstellglied mit dem zugehörigen Antrieb aber auch im Innern der Karosserie vorgesehen werden und angeordnet sein. Erfindungsgemäß hat sich jedoch die Anbringung des Antriebes und des Ausstellgliedes im Innern im Kraftfahrzeugtür bzw. an dem zugehörigen Türflügel als besonders günstig erwiesen, weil dann die weitergehende Möglichkeit besteht, den Schlossantrieb eines ohnehin obligatorischen Kraftfahrzeugtürschlosses im Innern der Kraftfahrzeugtür bzw. am Türflügel zusätzlich als Antrieb für das Ausstellglied nutzen zu können. Hierin sind die wesentlichen Vorteile zu sehen.The drive and the opening member are advantageously mounted inside the door leaf. In principle, however, the deployment member with the associated drive could also be provided and arranged in the interior of the body. According to the invention, however, the mounting of the drive and the opening member inside the vehicle door or on the associated door leaf has proven to be particularly favorable, because then there is the further possibility of using the lock drive of an already mandatory vehicle door lock inside the vehicle door or on the door leaf as a drive to be able to use for the opening member. This is where the main advantages can be seen.

Je nach einer von dem Elektromotor 8 initiierten Drehbewegung der Steuerscheibe 9 arbeitet die Steuerscheibe 9 auf die Sperrklinke 7, um diese von der Drehfalle 6 abzugeben. Den entsprechenden Befehl hierfür erhält der Elektromotor 8 über eine angedeutete Steuereinheit 10. Die Steuereinheit 10 mag wiederum den Öffnungsbefehl über einen Türschlüssel, die Annäherung eines Bedieners ("keyless entry") oder auch ganz einfach dadurch erhalten, dass der Bediener einen Türflügel betätigt.Depending on a rotational movement of the
Jedenfalls führt der zulässige Öffnungsbefehl dazu, dass die Steuereinheit 10 den Elektromotor 8 in dem Sinne beaufschlagt, dass dieser über die Steuerscheibe 9 das Gesperre 6, 7 wie beschrieben öffnet. Als Folge hiervon kann die Drehfalle 6 aufschwenken, wie dies in der
Von besonderer Bedeutung für die Erfindung ist nun noch der weitere Umstand, dass zusätzlich zumindest ein weiterer Antrieb 12, 13 - neben dem Schlossantrieb 8, 9 - vorgesehen ist. An den Antrieb 12, 13 ist ein Ausstellglied 14 angeschlossen, bei dem es sich im Ausführungsbeispiel um einen Ausstellstößel 14 handelt.The further fact that at least one
Der weitere Antrieb 12, 13 ist im Detail in der
Anhand der
Man erkennt anhand der
Da das Ausstellglied 14 als achsnah im Vergleich zu der Drehachse 2 des Türflügels 1 angeordnetes Linearstellglied ausgebildet ist, führt der fragliche Verstellweg x des Ausstellgliedes 14 aufgrund der Hebelwirkung am achsfernen Ende des Türflügels 1 im Vergleich zu der Drehachse 2 zu signifikanten und in der
Das alles lässt sich primär darauf zurückführen, dass das Ausstellglied bzw. der Ausstellstößel 14 achsnah im Vergleich zu der Drehachse 2 angeordnet ist und im Übrigen parallel zur Längserstreckung des Türflügels 1 verstellt wird. Dadurch kann das Ausstellglied 14 gegen die Wand 16 der Kraftfahrzeugkarosserie 3 fahren, und zwar jenseits der Drehachse 2 des Türflügels 1, wobei die fragliche Wand 16 darüber hinaus überwiegend senkrecht zur Längserstreckung des Türflügels 1 verläuft.All of this can primarily be attributed to the fact that the deployment member or the
Bei der bis jetzt beschriebenen Variante wird mit einerseits einem Schlossantrieb 8, 9 des Kraftfahrzeugschlosses 4 und andererseits einem separaten Antrieb 12, 13 für das Ausstellglied 14 gearbeitet. Es besteht aber auch die in der
Sofern eine mechanische Verbindung zwischen dem Schlossantrieb 8, 9 und dem Ausstellglied 14 realisiert ist, wird man an dieser Stelle bevorzugt mit einem Bowdenzug arbeiten. Der Bowdenzug kann dabei beispielsweise von dem Kraftfahrzeugtürschloss 4 bzw. dessen Antrieb 8, 9 derart beaufschlagt werden, dass mit Hilfe des Bowdenzuges bzw. des mechanischen Verbindungselementes 17 unmittelbar die Stellmutter 13 in Rotationen versetzt wird, damit auf diese Weise das Ausstellglied bzw. der Ausstellstößel 14 die gewünschte Linearverstellung unter Berücksichtigung des Stellweges x vollführt. Das ist grundsätzlich angedeutet.If a mechanical connection is implemented between the
Dabei wird man in beiden Fällen, d. h. bei einem separaten Antrieb 12, 13 für das Ausstellglied 14 ebenso wie für den Fall, dass der Schlossantrieb 8, 9 zugleich auch als Antrieb 8, 9 für das Ausstellglied 14 fungiert, so vorgehen, dass der Antrieb 8, 9 bzw. 12, 13 für das Ausstellglied 14 erst dann beaufschlagt wird, wenn das Gesperre 6, 7 im Kraftfahrzeugtürschloss 4 geöffnet ist. Dazu ist die Steuereinheit 10 in Verbindung mit dem Sensor 11 vorgesehen.In both cases, d. H. in the case of a
Das heißt, erst wenn der Sensor 11 ein entsprechendes Öffnungssignal an die Steuereinheit 10 abgibt, sorgt die Steuereinheit 10 dafür, dass entweder der Schlossantrieb 8, 9 den Ausstellstößel 14 wie beschrieben beaufschlagt oder sorgt dafür, dass der separate und zusätzliche Antrieb 12, 13 für das Ausstellglied 14 in entsprechendem Sinne beaufschlagt und ausgefahren wird. Als Folge hiervon wird dann der Türflügel 1 wunschgemäß wenigstens spaltweise gegenüber der Kraftfahrzeugkarosserie 3 geöffnet, so dass der Bediener den Türflügel 1 und damit die gesamte Kraftfahrzeugtür unschwer manuell vollständig öffnen kann.That is, only when the
