Setting device for a motor vehicle door element

The invention relates to a stand-up device for a motor vehicle door element, comprising an electric drive and an actuating means, the actuating means being adjustable by means of the drive and a gear arranged between the actuating means and the drive, and a sensor.

Today's motor vehicles are increasingly equipped with comfort functions. For example, to make it easier to get into a motor vehicle and to be able to influence the aesthetic and aerodynamic shape, motor vehicles are equipped, for example, without an external door handle. But it is also conceivable that an outer door handle is provided, but this forwards only a switching signal to the motor vehicle door lock. To make it easier to get in, to automate and to allow entry into, for example, handleless vehicles outside the door, so-called stand-up devices or door dividers are used, some of which are also referred to as door exhibitors.

From DE 10 2011 015 669 A1 an exhibitor for motor vehicle doors or flaps is known, with which a door, flap or hood can be moved from a closed position into an open position. If the adjustment device relates, for example, to a motor vehicle side door, the door can be moved by means of an electrical pulse be opened. To do this, the lock of the door lock must first be unlocked electrically, so that the door can be opened. If, for example, the door seal pressure is not sufficient to move the door from the closed position into an open position, the opening device can be used to move the door into an open position. An opening position is defined in such a way that the operator of the motor vehicle is able to grasp the door so that he can open the door completely. As Ausstellinrich device serves an electric drive that acts mechanically in the form of a pivoting movement of the lever on the motor vehicle door via a drive pawl and an inner and outer lever.

DE 10 2016 105 760 A1 discloses a set-up device for a motor vehicle door with a base plate, furthermore with a drive element mounted on the base plate and a drive, a first sensor being assigned to the drive element and being provided at least between a set-up process and a manual opening process differs. The AufStellvor direction includes a drive that can be driven by a sensor and a control unit. A flexible connection means then allows pivoting of a transmission lever, which in turn enables a positioning movement via a drive lever and a drive slide. To enable the door to be moved, the drive slide moves linearly and, for example, out of an opening in a body, so that an unlocked and unlocked door can be opened at least in some areas. The end position of the drive slide is fixed by means of a second Sensor can be detected so that the drive can in turn be switched off.

From the unpublished patent application by the applicant DE 10 2017 124 282 A1 an installation device for a motor vehicle door element has become known, comprising an electric drive and an actuating means, the actuating means being adjustable by means of the drive and a gear arranged between the actuating means and the drive. Movement of the door is made possible by means of the set-up device, a sliding element being arranged on the actuating means, which interacts with a switching means, so that the door movement can be detected. The actuating means is essentially made up of a driven toothed rack with an integrated sliding element, switching means and electrical feed line. By means of the switching means between the sliding element and the body, it is possible to control the movement of the driven rack.

The devices known from the prior art for setting up a motor vehicle door after unlocking a motor vehicle lock make it possible for the door to be able to be opened at least in some areas, so that an operator of the motor vehicle is able to grasp the door through a gap and completely close it to open. The known stand-up devices have proven themselves in principle, but reach their limits when the electrically operated doors are opened electrically, for example on a downhill road. This is where the invention comes in. The object of the invention is to provide an improved installation device for a motor vehicle door element. In addition, it is an object of the invention to provide a stand-up device which enables safe opening even on parked roads. In addition, it is an object of the invention to provide a structurally simple and inexpensive solution.

The object is achieved by the features of the independent claim 1. Advantageous embodiments of the invention are specified in the subclaims. It is pointed out that the exemplary embodiments described below are not restrictive; rather, any possible variations of the features described in the description and the subclaims are possible.

According to claim 1, the object of the invention is achieved in that an installation device for a motor vehicle door element is provided, comprising an electric drive and an adjusting means, the adjusting means being adjustable by means of the drive and a gear arranged between the adjusting means and the drive, so that a movement of the door is possible and a sensor, the door element being durable by means of the actuator. Due to the construction of the stand-up device according to the invention and in particular from the combination of a sensor, with which preferably a force acting on the drive unit can be detected and an adjusting means with which the door element is durable, the door can be opened, held and thus made available to one Operator possible. Due to the construction according to the invention, the door element can be presented to the operator, at the same time providing security against an independent opening of the door element. The vehicle can also be on a sloping road, the door element being durable by means of the adjusting means. If the door element is released electrically by means of the motor vehicle lock and the positioning device is activated, the door element opens automatically but only to the extent that an operator can grip the door element and open it manually. The opening device opens the door element only so far that the operator can grasp the door element, but at the same time there is no unintentional opening beyond the opening position by means of the splitting. There is therefore a high level of security that neither endangers people nor opens the door element itself into a danger area. The door preferably does not open any further than the overall width of the motor vehicle, that is to say including the mirror, for example.

The stand-up device is used in a motor vehicle door element. However, the motor vehicle door element can also be, for example, a flap, hood or cover, for example for a convertible roof. Holding the component that is movably arranged on the motor vehicle may also be necessary, for example due to environmental influences, such as in the case of wind, in order to prevent unintentional opening. The stand-up device can thus be used where a component which is movably arranged on the motor vehicle is positioned for further opening should. The stand-up device advantageously interacts with an electrically operated locking system, so that a high degree of design freedom is possible in the design of the door element. For example, the door element can dispense with a door handle, which results in almost any shape of an external shape of the door element.

Usually, the stand-up device is arranged in the area of the door element in such a way that the door element can be positioned by actuating the stand-up device. The stand-up device generates a relative movement between the body and the door element, the Aufstellvor direction is preferably arranged in the door element itself. An arrangement in the body for moving the Türele element is of course also conceivable. It is also conceivable that the stand-up device is integrated in the motor vehicle lock, for example a side door. This offers the advantage that an electrical voltage is available for the drive and / or that further functions in the motor vehicle lock can be actuated by the drive.

The electric drive preferably consists of a direct current motor which interacts with the actuating means with an output shaft and for example via a worm gear. One-, two-, or multi-stage transmissions are conceivable, whereby the selection of the transmission can influence the available force on the actuating means. For example, the installation device is arranged in the door element in such a way that the installation device has an A-pillar, for example Motor vehicle and a front door cooperates, so higher forces are required to set up the door element than if the set-up device is in turn arranged in a front door of a motor vehicle and acts on a B-pillar in the motor vehicle. In the case of dividing a door and arranging the positioning device in the area of the motor vehicle lock, lower forces are necessary, so that higher ratios can be used.

The electric drive enables the actuator to move. By means of the electric motor it is possible to move the adjusting means in such a way that the door can be opened by the driven adjusting means. The actuating means moves relative to the body series and exerts a compressive force on the vehicle door element, so that the unlocked and unlocked door can be moved.

The stand-up device preferably interacts with a motor vehicle lock which has a catch and at least one pawl, the locking mechanism consisting of a catch and at least one pawl being electrically lockable. In particular in the case of electrically unlockable locking systems, the operator of the motor vehicle only needs an electrical pulse to move the locking system into an unlocked, that is to say open, position. The locking system is then open so that the door or flap can be moved. The electrical opening pulse for motor vehicle lock can be by means of a sensor, a key or by means of, for example a sensitive means, such as a touch sensor or an outside door handle with an integrated sensor.

Once the vehicle door element is unlocked, the door element can be pivoted freely in the hinges. If necessary, the door also has a door stop strap, which can hold the door in several opening positions. The unlocked door can then be moved by means of the set-up device, the movement of the vehicle door element being detectable by sensors. The complete installation process is recorded. There is a continuous detection, so that the door movement can be detected at any time during the movement of the vehicle door element by means of the positioning device. A door that is manually moved beyond the movement of the opening device separates the sensor detection so that the electric drive can be switched off or the electric drive can be reversed so that the actuating means can be moved back into its starting position. The detection of a manual movement of the vehicle door element is explained in detail below.

In an embodiment variant of the invention, the actuating element has a locking means, in particular a locking lever. By means of a locking means integrated in the control element, the possibility is now created of realizing a secure holding of the vehicle door element in addition to the sensory detection of the control movement. By means of the locking means, it is possible for the vehicle door element to be Device generated movement of the door element to guide and hold the vehicle door element. The guiding and holding of the door element means that not only an automatic installation of the door element is possible, but rather the possibility is also created to achieve a closing movement by means of the opening device. The opening device can thus also be referred to as a combined opening and closing device.

If the locking means can be positively connected to the body of the motor vehicle, there is a further embodiment of the invention. If, for example, the motor vehicle door element is opened electrically, that is to say the locking mechanism is unlocked, the door element can be freely pivoted in the hinges. Now the AufStellvor direction can set up the door element, wherein the locking means is positively engaged with the body. It can thus be guaranteed a secure hold at any time during the movement of the door element by means of the installation device. A form fit is advantageous because the security when holding the door element can be increased. The positive connection can take place for example by means of a recess in the actuating means and a spring-loaded locking means which can be brought into engagement with the recess. The depression can be present in the body or in the adjusting means, as can the locking means on the body or on the adjusting means. The locking means can be in the form of a hook, ball or also in the form of a bayonet lock, for example. The locking means can be spring-loaded, for example engage a recess, undercut or recess. In any case, such a positive connection can be produced by means of the locking means that the vehicle door element can be securely held over the entire range of movement of the positioning device. A release of the locking means from the positive connection is then possible for example by means of a manual movement of the motor vehicle door element.

The connecting means can advantageously be releasably engaged with the body. The release can be done for example by manual operation of the vehicle door element. To do this, the operator must, for example, manually grasp the door element after setting up the door element and move it beyond the installation path. The locking means can consist, for example, of a spring-loaded ball or also a plurality of spring-loaded balls, which, for example, engage the body in a form-fitting manner and can be moved out of the engagement area with the body. The force of the positive locking is overcome by the manual actuation of the door element.

As will be explained further below, the electrical drive receives an electrical signal after the connection means has been released with the body, as a result of which a return of the adjusting means to the initial position can be initiated. A spring-assisted releasability of the connecting means is advantageous, since this means that a permanently stable locking means can be implemented. It is also conceivable according to the invention that, for example, an elastic locking means is used, whereby by means of a elastic plastic element a form fit between

Positioning means and body can be produced. For example, the locking means can be arranged at one end of the adjusting means and, for example, have a ball shape which engages in a form-fitting receptacle of an elastic plastic element in the body.

In a further embodiment variant of the invention, the locking means can be driven and controlled electrically, in particular can be driven and controlled by means of an electric motor drive. An electrical control of the locking means enables increased security when establishing a connection between the actuating means and the body. It is conceivable, for example, that a locking lever is arranged in the actuating means, which can be actuated by means of a locking slide. If, for example, the locking lever is pivotally arranged in the adjusting means at a radial end of the adjusting means, pivoting of the locking lever can be initialized by means of the locking slide. The pivoting of the locking lever can then be used to intervene in the body. As long as the locking slide is in engagement with the locking lever, the door element can be held securely.

If the locking slide is disengaged from the locking lever, the locking lever can, for example, be spring-loaded or be disengaged from the bodywork by manual actuation of the door element. The locking slide is for example displaceably driven in the actuating means and, for example, can be moved back and forth in the actuating element via an electrically driven spindle gear. The locking slide can, for example, have a locking cone that can be brought into engagement with the locking lever, the locking lever being pivotally received in the adjusting element or adjusting means or, for example, in two parts and being spreadable, so that the locking lever, for example, positively behind the ver locking contour can reach. In a one-piece construction of the locking lever, one-sided engagement in the body is conceivable, with a two-part construction of the locking lever, for example, a mutual pivoting of the locking lever is conceivable, so that two-sided engagement, that is, spreading into the body or the Locking contour into it he can follow.

It can also be advantageous if the locking means has an actuable, in particular displaceable, locking slide which can be actuated by means of the electric drive. To operate the locking lever, the locking slide is pushed by the drive us preferably using a spindle gear ver. In other words, the motor can carry a spindle on its drive shaft, the spindle interacting directly with the locking slide, so that the locking slide can be moved back and forth. The spindle gear is preferably not self-locking, which is particularly advantageous when an emergency operation described in the following comes to use. In a further embodiment variant, the locking lever can be actuated by means of the locking slide, in particular pivotable. The locking slide can be moved by means of the spindle drive and thus comes into engagement with the locking slide. The locking slide is pivotally but fixedly accommodated in the adjusting element. Advantageously, locking latches and locking levers have a cooperating contour, for example in each case a conical end, so that meshing is facilitated and pivoting of the locking slide is supported. If the locking slide engages with the locking lever, the locking lever is pivoted and at the same time held in its pivoted position. The locking slide thus serves as a positioning lock for the locking lever. If the locking lever comes into engagement with a locking contour, a secure installation or closing is possible by means of the installation device.

A further embodiment variant of the invention results when the locking means is integrated in the control element. On the one hand, a space-saving set-up device can be realized by an integrated design, and on the other hand the components of the locking means can be protected against environmental influences. The locking means is arranged in the actuating element, the actuating element being moved out of the door element, so that rain, snow, dust and other environmental influences are exposed. Thanks to the integrated solution, it is now possible to use the locking means means protecting the drive, the gearbox, the locking slide and the locking slide from environmental influences. This is particularly advantageous because the components of the locking means are formed from mechanically mounted parts which, for example, rely on lubrication and in that the environmental influences cannot impair the function.

Advantageously, the locking lever can be brought into engagement with a locking contour, in particular the locking lever can be brought into engagement with a locking contour by means of a damping means. The locking lever is pivotable by means of the locking slide, so that the locking lever is able to engage in a contour of the body of the vehicle. The body preferably has a locking contour which can also be formed separately. This means that the locking lever can engage, for example, in an opening in the body or act together with a locking contour attached to the body. In any case, a form fit can be achieved by the interaction of the locking lever and locking contour, so that a targeted and safe introduction of a force from the actuating means onto the body is possible. The stand-up device is consequently able to firstly find a stable and stationary support when the door element is set up, secondly to enable the door element to be held in the open position and thirdly to allow the door element to be closed by means of the stand-up device. Through the use of a damping agent, the interaction of the locking slide and the locking mechanism can be improved, in particular a low-noise engagement, guiding and holding of the door element can be guaranteed. The damping means can be mounted on the locking lever, molded on, positively held or arranged in a comparable manner. In addition, however, it is also conceivable according to the invention that the damping means is arranged in the area of the body and / or on the locking contour.

In one embodiment variant of the invention, the locking means has an emergency actuation, so that the locking means can be unlocked manually. For example, there may even be an engagement surface on the locking slide, by means of which a manual release of the locking slide is possible. The locking slide can be brought out of engagement with the locking lever manually in order to bring about a loosening of the locking means with the body. The emergency operation can also be formed, for example, from a push button that separates the locking lever, for example. In this case, the locking slide can be formed in two parts, for example, so that a release of the locking means with the body is possible.

Furthermore, it is conceivable according to the invention that the emergency actuation is formed from an engagement contour, in particular a shaft contour, on the locking slide. In other words, the adjusting element can have an opening from which the engagement contour protrudes or through which the engagement contour can be grasped. A shaft contour offers the advantage that the emergency actuation can be felt easily and, on the other hand, the introduction of force into the actuation or engagement contour is improved. By means of the emergency actuation, the locking slide is moved into an initial position, so that the locking slide disengages from the locking lever. To do this, the locking slide must be actuated via the spindle drive, but, as described above, it cannot advantageously be designed to be self-locking.

Furthermore, it is conceivable according to the invention that at least one gear component is pivotally received in the positioning device, in particular in a gear carrier of the positioning device. An overload safety device can be implemented by pivoting mounting of at least one component of the gearbox. In particular, in the event that the door element is subjected to an excessive load, overload protection can be implemented by means of the pivotable gear component. An excessive load can occur, for example, if, for example, the door element cannot be opened due to weather conditions, that is to say if, for example, the door seal is iced up. On the other hand, it can also happen that, for example, the door element is manually actuated by an external blocking of the door element or before the end position of the door element is reached by means of the positioning device. In the event of this excessive load, the swiveling gear component can prevent damage to the positioning device and compensate for movements. If a force measuring device, in particular a Hall sensor, is arranged on the transmission carrier, a further embodiment variant of the invention results. A movement of the transmission carrier can be detected by the force measuring device on the transmission carrier, as a result of which an excessive load on the positioning device can be detected. A Hall sensor lends itself to this, since it enables a contactless detection of a movement and in particular also the detection of small paths of the gearbox carrier to be detected. The force measuring device is coupled to the drive of the stand-up device and to a control in the motor vehicle, so that upon detection of an excessive load on the stand-up device, by means of detection of a movement by the force-measuring device of the transmission carrier, reversing or stopping of the drive motor the stand-up device can be initiated. At the same time, a control signal can also be passed to the locking means in order to stop, prevent or cancel a locking mechanism, for example. The force measuring device thus serves as a control element and prevents damage to the Aufstellvor direction.

According to the invention, the gear carrier can cooperate with a spring element, wherein a pivoting movement of the gear carrier can be cushioned. The connection of the gearbox to a spring element makes it possible to secure a central position of the gearbox. A central position of a gearbox is important because on the one hand tensile loads as well as pressure loads can occur on the actuating means. In this case, for example, an operator can open the door element before the locking means has been released or, for example, press the door element closed while the opening device opens the door element. In both cases, the gear carrier can be spring deflected by means of the spring element. The gear carrier can be pivotally received in the positioning device and pivoted about a pivot axis from a central starting position in two loading directions. The force measuring device, in particular the sensor device, is advantageously arranged on the gear carrier in such a way that a movement of the gearbox carrier in both directions of movement can be detected by means of the force measuring device.

Advantageously, the spring element is a Blattfe the. By means of a leaf spring, on the one hand, a sufficiently high force can be provided to secure the central position of the gear carrier and, on the other hand, provide sufficient backlash for the gear carrier. The inventive construction of the stand-up device enables the door element to be held securely while at the same time ensuring a high level of operational safety.

The invention will be explained in more detail with reference to the accompanying drawings using a preferred embodiment example. However, the principle applies that the exemplary embodiment does not limit the invention, but merely represents one embodiment. The features shown can be used individually or in combination with other features of the description the claims can be performed individually or in combination.

Direction of arrow II from Fig. 1, wherein a position of the stand-up device is given again, in which a tensile load acts on the stand-up device and Fig. 7 shows a view of the stand-up device according to arrow II from FIG. 1 under a pressure load, that is to say a load in the direction of the body, acts on the stand-up device.

FIG. 1 shows a three-dimensional view of a stand-up device 1 with the components essential for the explanation of the invention. On the adjusting device 1 is arranged in a motor vehicle door element 2, an adjusting means 3 being in engagement with a body 4. In this respect, the extended position of the adjusting means 3 is shown, so that in this state the opening device 1 has moved and set up the door element 2 via the adjustment path S. In the illustrated position, the vehicle door element 2 can consequently be grasped by an operator and can further be opened manually.

The set-up device has an electric drive 5, a gear 6, a force measuring device 7, a housing 8 and the actuating means 3. The drive 5 is preferably formed from an electric DC motor with an output shaft 9 and a gear 10 located on the output shaft 9. In this exemplary embodiment, the transmission 6 is of multi-stage design, with a first transmission stage 11 being directly engaged with the output of the electric drive 5. By means of the first gear stage 11, a second gear stage 12 is driven, the second gear stage 12 with a rack 13 on the actuating means 3 in Engagement. Via the drive 5 and the two gear stages 11, 12, the actuating means 3 is consequently adjustable in the direction of the arrow PI. The actuating means 3 can be moved out of the housing 8 and into the housing in the direction of the arrow PI.

A gear carrier 14 forms a first fixed bearing for the first gear stage 11, the second gear stage 12 being pivotally received by means of the gear carrier 14 in the adjusting device 1. In this embodiment, for example, a leaf spring 15 is fastened to the gear carrier 14, the leaf spring 15 being fixedly connected on one side to the gear carrier 14 and arranged on the side opposite the gear carrier 14 in a fixed bearing 16. To detect a pivoting movement of the gear carrier 14, a sensor 17, in particular a Hall sensor, is arranged in a fixed manner in the positioning device 1 and connected by means of electrical contacts 18 to a control device (not shown). Of course, the sensor 17 can also be arranged on the gear carrier 14.

A guide means 19 is arranged on the rack 13 against the opposite side of the actuating means 3 in the Aufstellvor direction 1, on the one hand to enable smooth operation of the actuating means 3 and at the same time to provide a stable guide for the actuating means 3. The guide means 19 can be, for example, a bearing or a roller or a combination of bearing, roller and / or damping means.

The adjusting means 3 has an electric drive 20, the output shaft 21 of which in this exemplary embodiment Spindle 22 drives, the spindle 22 extends into a locking slide 23 and interacts with the locking slide 23. The locking slide 23 is slidably received in the adjusting means 3. The locking slide 23 works with a locking lever 24, the effect of which will be explained in more detail below.

Also shown in FIG. 1 is an emergency actuation 25, which in this embodiment is formed as a shaft contour, the locking slide 23 being operable manually by means of the emergency actuation 25, so that the locking lever 24 is manually disengaged from the body 4 and in particular a locking contour 26 can be brought.

The electrical contacting of the drives 5, 20 and the sensor 17 are not explicitly reproduced, the electrical components 5, 17, 20 being electrically connected to a control unit (not shown) within the mounting device 1 and / or the motor vehicle itself.

In Figure 2 is a side view of the Aufstellvor direction 1 according to arrow II from Figure 1 reproduced ben, wherein the adjusting means 3 is shown in a retracted position. The same components are provided with the same reference symbols. The axis 27 of the first gear stage 11 can be clearly seen, the axis 27 being fixed in the mounting device 1 and at the same time forming a pivot axis 27 for the gear carrier 14. The gear carrier 14 includes a bearing 28 for the second gear stage 12, the second gear stage 12 and in particular the bearing point 28 being shown in a starting position A. The gear carrier 14 can be pivoted about the starting position A in both directions via the axis 27 in the direction of the arrow P2. By means of the leaf spring 15, the gear carrier 14 is held in the starting position A and secured spring-loaded.

The retracted position of the actuating means 3 shown in FIG. 2 corresponds to a closed door element 2, the actuating means moving into the Aufstellvor direction 1 in the direction of arrow P3 as shown. The door element 2 is held, for example, by means of a motor vehicle lock in the closed position.

FIG. 3 shows a view of the positioning device 1 from the direction of the arrow III from FIG. 2. In Figure 3, the actuating means 3 is shown in a maximally extended position, in which the installation device 1 has moved the door element 2 over the travel path or travel path S. The locking means 29 secures the door element 2 in the holding position. The Verrie gelmittel 29 is formed in this embodiment from the drive 20, the spindle drive 22, the locking slide 23 and the locking lever 24. The locking lever 24 is received in the adjusting means 3 so as to be pivotable about the axis 30. The locking lever 24 engages with an extension 31 in an undercut 32 of the locking contour 26. The locking lever 24 is pivoted through the locking slide 23 into the locking contour 26, wherein the locking lever 24 pivots about the axis 30. At the end, the adjusting means 3 can have a damping means 33 in order to enable a low-noise interaction between the positioning device 1 and the body 4.

In Figure 4, the position of the locking slide 23 is now shown, in which, for example, the operator has manually gripped the door element 2 and applied a force F to the adjusting device or the door element 2 in the direction of arrow P4. This actuation of the opening device 1 or the door element 2 can be detected by means of the sensor 17, as will be explained in more detail below. The movement of the Aufstellvor direction 1 in the direction of arrow P4 causes the electric drive 20 to be actuated, so that the locking slide 23 is retracted in the direction of arrow P5 within the actuator 3. By pulling back the locking slide 23, the locking lever 24 is released and can be pivoted about the axis 30.

FIG. 5 now shows the position of the locking lever 24, into which the locking lever 24 comes when the door element 2 is actuated or moved. The locking lever 24 pivots in the direction of arrow P6 around the axis 30 in the adjusting means 3 and thus disengages from the locking contour 26. The door element 2 can now be moved freely and the adjusting means 3 can be moved into the positioning device 1. In FIG. 6, a side view from the direction of arrow II from FIG. 1 is again shown on the installation device 1. Shown is a position of the gear carrier 14, which the gear carrier 14 takes when a tensile force FZ acts on the actuating means 3. It is consequently a force measurement using the sensor (17). This tensile force FZ acts when the locking means 29 is in engagement with the locking contour 26 and additionally a movement in the direction of arrow P7 into the positioning device 1 is initiated, for example by manual gripping and opening of the door element 2. The Gear carrier 14 pivots through the angle OCl, whereby the gear carrier 14 is displaced by the angle OCl, the adjustment angle OCl being clockwise around the starting position A. This pivoting of the gear carrier 14 can be detected by means of the fixed sensor 17. A curvature 34 of the leaf spring 15 around the rest position R can also be clearly seen. The leaf spring 16 is received in a fixed but pivotable manner in the fixed bearing 16. Figure 6 thus shows the situation in which the Aufstellvor direction 1 gets when the set-up device has moved the Türele element 2 and the door element 2 is gripped and pulled up by an operator, for example. The sensor 17 detects this tensile force FZ of the operator and initiates an unlocking of the locking means 29 in the form described above.

FIG. 7 now shows the situation in which a compressive force FD is introduced into the positioning device 1. The transmission carrier becomes due to the pressure force FD 14 is pivoted counterclockwise in the direction of the angle 0 (2 around the axis 27, which in turn can be detected by means of the sensor 17 and the relative movement between the sensor 17 and the gear carrier 14. The leaf spring 15 in turn undergoes a curvature 35. In this case the drive 5 would of the actuator 3 of the control activated and the actuating means 3 in the on _S tellvorrichtung 1 moves in. This can, for example, then take up, if the operator wishes to close the motor vehicle immediately after the opening and installation manually. in this case, the manual closure may assisted or automatic closing means of the on _S tellvorrichtung 1 are introduced the Aufstellvor direction. 1 then acts as a closing device for the door element 2, wherein the door element 2 by means of the electric drive 5, the transmission 10, 12, the actuating means 3 and the locking means 29 pulled into a closed position w earth To tighten, the extension 31 of the locking means 29 engages behind the locking contour 26 on the body 4.
