Description

The invention relates to a door handle arrangement for a motor vehicle, having a handle support, a handle and a drive element, the handle being able to assume at least one rest position and one handling position, and the handle being flush with the outside of the vehicle door when installed in a vehicle door in the rest position is arranged to run and in the handling position for actuation is arranged exposed in relation to the outside of the vehicle door in an opening direction, with a base plate being movably mounted on the handle support, which can be moved relative to the handle support and on which the handle is mounted, and wherein the drive element with the base plate is coupled for movement and in normal operation the base plate is designed to move from a basic position, in which the handle is arranged in its rest position, into a ready position, in which the handle is arranged in its handling position.

Such door handle arrangements for a motor vehicle can be designed as an inside or outside handle, the present invention relating to a door handle arrangement for an outside handle. There are a variety of different constructions and embodiments for such door handle assemblies. The design of a door handle according to the invention relates to constructions in which the handle support is attached to the back of the vehicle door, ie on the inside of the motor vehicle. In such embodiments, the handle attached to the handle support usually protrudes from the vehicle door and disturbs both the aesthetic impression of the motor vehicle and the vehicle aerodynamics. Around To avoid disadvantages, door handle arrangements are known from the prior art, in which the outside of the handle in its rest position, in which it is not used, runs approximately flush with the outer contour of the vehicle door, ie flush with the street. To open the vehicle door, such a handle can be transferred into a handling position in which the handle protrudes relative to the outer contour of the vehicle door.

A door handle assembly of the type referred to, for example, for electric cars from Tesla Motors Inc. and from DE 10 2013 212 198 A1 known. This known door handle arrangement has a handle which is arranged flush with the street in its rest position and which can be moved, driven by a motor, from the rest position into a handling position. Such a handle is preferably used in electric cars in which the handle extends exclusively with a power-driven drive from its rest position flush with the street, in which the handle is arranged to reduce air resistance, into the handling position when an authorized operator approaches the motor vehicle. As soon as the handle is no longer needed, it moves back into the rest position and thus disappears into the body to avoid generating air resistance. The disadvantage is that the door handle arrangement has a complex structure for the extension mechanism and a large installation depth associated therewith.

The invention is based on the object of creating a solution that provides an improved door handle arrangement for a motor vehicle in a structurally simple manner, the door handle arrangement having a space-saving design with a low installation depth and still enabling convenient operation.

In a door handle assembly of the type described above, the object is achieved in that the base plate along at least one transverse to the handle support guide rod between the basic position and the Ready position is movably guided. According to the invention, the current-operated normal operation represents an operating mode in which the drive element then moves the handle from the rest position to the handling position when an authorized operator approaches the motor vehicle with his ID transmitter. In the handling position, the authorized operator can then reach behind the handle and pull on it in order to open the motor vehicle door. The movement of the base plate during the raising movement of the handle is directed in the raising direction.

Advantageous and expedient refinements and developments of the invention result from the dependent claims.

The invention provides a door handle arrangement for a motor vehicle that is characterized by a simple construction with a small installation depth. A characteristic of the invention is the small number of components required to move the handle from the rest position to the handling position. Because only the base plate on which the handle is mounted is provided for issuing the handle in the handling position. According to the invention, the handle is arranged in its rest position when the base plate is arranged in its basic position. If the base plate is moved from the basic position into the ready position by a movement in the opening direction, the handle mounted on the base plate moves with the base plate and reaches its handling position without the handle moving relative to the base plate. The handle is consequently mounted on the base plate, which advantageously increases the stability of the handle. Of course, within the meaning of the invention, the base plate can also have a guide rod at each of its two longitudinal ends, as a result of which the base plate is held in a stable manner and guided securely.

In an advantageous embodiment, the invention provides that the handle is arranged stationary on the base plate when the base plate is moved from the basic position into the ready position, the base plate being designed to move the handle from the rest position into the handling position. Consequently, the base plate represents the only component which is used to issue the handle in the handling position, so that an operator can reach behind the handle in the handling position and actuate it to open the vehicle door.

In an embodiment of the invention, it is further provided that the handle is mounted on the base plate so that it can move relative to the base plate, with a first longitudinal end of the handle being mounted pivotably on the base plate, whereas a second longitudinal end of the handle is designed to be pivotable in the deployment direction by an operator and connected to vehicle door opening means. It is therefore a handle that an operator has to pull to open the vehicle door during normal operation, in which the handle is electrically deployed by the drive element, the handle then assuming a skewed position aligned transversely to the handle support.

So that the door handle arrangement can also be used to open the vehicle door in an emergency, in which the power supply is interrupted or has failed and the handle is not moved electrically into the deployed handling position, the invention provides in a further embodiment that the handle can be moved from the rest position in an emergency operating position, in which a first section of the handle is arranged to be moved counter to the raising direction and a second section of the handle is arranged raised relative to the outside of the vehicle door in the raising direction. Due to the pivotable mounting, it is consequently possible to use the handle on one section, preferably at one longitudinal end, to press against the deployment direction in the direction of the handle support, so that this section disappears within the body. Another section of the handle, preferably a section of the other longitudinal end of the handle, is positioned opposite the vehicle door and an operator can reach from behind to manually move the handle as a whole into the handling position, from where the handle can be used to open the vehicle door can be drawn.

To move the handle into the emergency operating position, the invention provides in a further embodiment that the handle has an outer handle shell and a main handle lever, with a first longitudinal end of the outer handle shell being pivotably mounted on a first longitudinal end of the main handle lever, with the main handle lever having its first longitudinal end on the Base plate is pivotally mounted, and wherein in the emergency operating position of the handle, the first longitudinal end of the outer handle shell is arranged to move counter to the deployment direction and the first longitudinal end of the outer handle shell is arranged to move relative to the first longitudinal end of the main handle lever. The main handle lever is coupled to the vehicle opening means, so that the connection of the outer handle shell and the main handle lever ensures decoupling such that when the handle is in a de-energized emergency operation, only the outer handle shell is pivoted into the emergency operating position. The main handle lever coupled to the vehicle opening means remains unmoved, so that there is no risk of the vehicle opening means being triggered accidentally when moving into the emergency operating position.

So that the outer handle shell is not pivoted relative to the main handle lever during normal operation when the operator pulls on the handle to open the vehicle door, the invention provides in an embodiment that a latching recess is formed on the second longitudinal end of the outer handle shell, with a Relative movement between The safety lever blocking the outer shell of the handle and the main handle lever is pivotably mounted with a latching hook on the main handle lever, and the latching hook is in engagement with the latching recess when the handle is in the handling position. This ensures that the outer shell of the handle and the handle lever pivot together in normal operation when an operator pulls on the handle to open the vehicle door.

In order to bring the locking hook of the safety lever into engagement with the locking recess, there is a structurally particularly favorable possibility that a movement web is formed on the handle carrier and the safety lever, which is in the rest position of the handle, is out of engagement with the locking recess, can be pivoted about an axis on the Handle main lever is mounted, wherein the moving bar pivots the safety lever during the movement of the handle from the rest position into the handling position of the handle about the axis and in the handling position of the handle the latching hook is designed to bring the latching recess into engagement.

According to one embodiment, the invention provides that the drive element is movably coupled to a drive lever, which is mounted rotatably about a lever axis on the handle support, with the drive lever having a drive pin at its free end, which is positioned within a slot formed in the base plate and running transversely to the deployment direction is arranged such that the drive element moves the drive pin via the drive lever within the elongated hole and the drive pin urges the base plate into its ready position. In this way, a kind of guide link is formed, through which the base plate is pushed into its ready position.

In order to realize the movement of the base plate in the opening direction, the invention provides in an embodiment that the drive element rotates about an axis of rotation during normal operation rotatable coupling lever drives, wherein a free end of the coupling lever is formed with a coupling pin which rests against the drive lever during movement of the handle from the rest position into the handling position and rotates it about its lever axis.

In order to also block the movement of the base plate in the opening direction, a stop element could be implemented on the at least one guide rod. As an alternative to a stop element, the invention provides for the coupling pin to be arranged in a pin receptacle formed on the drive lever when the base plate is in the ready position, with the coupling pin being arranged in the pin receptacle blocking movement of the base plate beyond the ready position in the opening direction.

It goes without saying that the features mentioned above and those that are still to be explained below can be used not only in the combination specified in each case, but also in other combinations or on their own, without departing from the scope of the present invention. The scope of the invention is defined only by the claims.

In figure 1 a motor vehicle 1 in the form of a car is shown as an example, which in the example has four vehicle doors 2 (two of which are figure 1 visible) has, which can be opened via a respective door handle assembly 3 and in particular with the help of a handle 4 of the door handle assembly 3. The vehicle doors 2 are firmly closed via a respective door lock 5 and can only be opened from the outside via a respective movement of the handle 4 . This movement on the handle 4 consists of a pulling movement, the corresponding movement of the handle 4 being transmitted to the corresponding lock 5 via a vehicle door opening means 6, which in the present case is a Bowden cable system. The associated vehicle door 2 can then be opened by the corresponding movement of the handle 4 . In the event of a currentless emergency operation, the door handle arrangement 3 is designed in such a way that the vehicle door 2 can also be opened manually by actuating the handle 4 by an operator.

the figure 2 shows a perspective view of one of the vehicle doors 2 and the handle 4 used to open the vehicle door 2. In FIG figure 2 is the handle 4 - when installing the door handle assembly 3 in the vehicle door 2 - arranged approximately flush with the outside 7 of the vehicle door 2, ie flush with the street or flush with the surface. In this position, the handle 4 is in a rest position in which it is not used. from the inside figure 2 In the rest position shown, the handle 4 is in a figure 3 shown handling position transferable, in which it protrudes from the outside 7 of the vehicle door 2 . Accordingly, the handle 4 is arranged protruding from the vehicle door 2 in its handling position. In this handling position that protrudes or is extended from the outside 7 , an operator can reach behind the handle 4 and actuate or handle it in order to open the vehicle door 2 . According to the present invention, the handle 4 is transferred from the rest position to the handling position in a power-driven normal operation by means of a drive element 8 (see, for example, figures 13 and 24 ). For current-operated normal operation, proximity sensors or other sensors can be provided in order to bring the handle 4 from the flush or flush rest position into the ready position as soon as an operator approaches the vehicle door handle 3 or the handle 4 . For this purpose, proximity sensors known from the prior art can be installed in the handle 4, which, when an authorized operator or ID transmitter is detected, send a signal to a vehicle control device, whereby the drive element 8 is put into operation and the handle 4 into the handling position. In a powerless emergency operation, for example in the event of a failure of the vehicle electronics or vehicle power supply, the handle can be manually moved from the rest position by an operator to an in figure 4 shown emergency operating position are moved. In the emergency operating position, a first section 4a of the handle 4 is arranged pressed inwards into the outside 7 of the vehicle door 2 , whereas a second section 4b of the handle 4 is arranged out of the vehicle door 2 . Thus, in a de-energized emergency mode, the handle 4 can be placed in its emergency mode position by an operator pushing the first portion 4a of the handle 4 inwardly with respect to the vehicle door 2 so that the second portion 4b of the handle 4 is positioned exposed and away from the operator attacked can be used to convert the handle 4 into its handling position, in which the vehicle door 2 can then be opened by pulling on the handle 4 .

The door handle arrangement 3 according to the invention is in figure 5 shown in a perspective rear view. The door handle arrangement 3 comprises the handle 4 and a handle support 9 which can be attached to a vehicle door 2 on the inside. The handle support stores or carries the other components of the door handle arrangement 3, with components also being able to be attached to the handle support 9. The drive element 8 can be attached to the handle support 9 or to the vehicle door 2 or in the area of the vehicle door 2 . In the Figures 2 to 4 the handle support 9 can be seen behind the outside 7 of the vehicle door. How from the Figures 5 to 7 can be seen, a base plate 10 is mounted on the handle support 9, which is movable relative to the handle support 9 and on which the handle 4 is mounted. the Figures 6 and 7 show quasi-transparent views of the door handle assembly 3, wherein in figure 6 the base plate 10 is in a basic position and at the same time the handle 4 mounted on the base plate 10 is in its rest position, whereas in figure 7 the base plate 10 is in a ready position and at the same time the handle 4 mounted on the base plate 10 is in its handling position. As the comparison of the different positions of the base plate 10 and handle 4 in the Figures 6 and 7 shows, the handle 4 is arranged unmoved on the base plate 10 when the base plate 10 moves from the basic position into the ready position. Consequently, when the base plate 10 is moved from the basic position into the ready position, the handle 4 is also moved without the handle 4 moving relative to the base plate 10 . Accordingly, the base plate 10 is designed to move the handle 4 from the rest position into the handling position, which will be discussed in detail below. The movement of the base plate 10 and the handle 4 takes place in a direction transverse to the handle support 9 deployment direction 14, which consists of the Figures 6 and 7 example can be seen.

In the figure 8 the base plate 10 is moved into its ready position, so that the handle 4 is arranged in its handling position. In the handling position, an operator can pull on the handle 4 to open the vehicle door 2, so that the handle 4 is pivoted relative to the base plate 10, as shown in FIG figure 9 is shown. The pivoting of the handle 4 actuates the vehicle door opening means 6 designed as a Bowden cable, so that the vehicle door 2 can be opened by pivoting. Consequently, the handle 4 is mounted on the base plate 10 so that it can move relative to the base plate 10 . More precisely, a first longitudinal end 11 of the handle 4 is pivotably mounted on the base plate 10 , whereas a second longitudinal end 12 of the handle 4 is designed to be pivotable by an operator in the deployment direction 14 and is coupled to the vehicle door opening means 6 . The handle 4 is thus about a pivot axis 15 (see for example Figures 8 and 9 ) pivotably mounted on the base plate 10 and is pivoted to open the vehicle door 2 by an operator from the handling position. For reasons of clarity, in figure 6 the handle support 9 is not shown. Details of the coupling of base plate 10 and handle support 9 are described in more detail below.

Previously be related to the Figures 10 to 16 inventive features of the handle 4 described. This is because the handle 4 is not designed in one piece, as is known from the prior art, but in two parts. How in particular figure 12 shows, the handle 4 comprises a handle outer shell 16, which can be reached from behind by an operator and on which the operator pulls to actuate or open the vehicle door 2, and a main handle lever 17. The outer handle shell 16 and the main handle lever 17 are together connected, wherein the handle main lever 17 is additionally rotatably connected to the base plate 10 via the pivot axis 15. A spring element ensures that the handle 4 is returned to its handling position (see Fig figure 8 ) when the handle 4 is pulled to open the vehicle door 2 (see figure 9 ). A first longitudinal end 16a of the outer grip shell 16 is pivotably mounted on a first longitudinal end 17a of the main grip lever 17 via a coupling axis 18, the main grip lever 17 being pivotably mounted on the base plate 10 via the pivot axis 15 at its first longitudinal end 17a. A coiled around the coupling axis 18 spring element 19 holds the handle outer shell 16 in the Figures 8 to 11 shown position.

The reason for the two-part design of the handle 4 can be found in the fact that the door handle arrangement 3 is equipped with an emergency actuation feature for emergency operation without current, i.e. for a case when the drive element 8 cannot be energized to move the handle 4 from the rest position to the to move handling position. In such an emergency operation, the operator still has the option of manually moving the handle 4 into the handling position in order to open the vehicle door 2 . To do this, the operator must exert a force on the first longitudinal end 16a of the outer handle shell 16 that acts counter to the raising direction 14 and press the outer handle shell 16 at its first longitudinal end 16a in the direction of the handle carrier 2 or counter to the raising direction 14, as a result of which the outer handle shell 16 is pressed against the force of the Spring element 19 is pivoted about the coupling axis 18, which in figure 13 is indicated as an example. In figure 13 the handle 4 is arranged in an emergency operating position, which is characterized in that the first longitudinal end 16a of the outer handle shell 16 is arranged so that it moves counter to the deployment direction 14 and the first longitudinal end 16a of the outer handle shell 16 moves relative to the first longitudinal end 17a of the Handle main lever 17 is arranged. The handle 4 is consequently designed to be movable from the rest position into the emergency operating position, in which a first section 4a of the handle 4 is arranged so that it is moved counter to the deployment direction 14 and a second section 4b of the handle 4 is arranged in a raised position opposite the outside 7 of the vehicle door 2 in the deployment direction 14 is. As figure 13 shows, the relative pivoting of the outer grip shell 16 and the main grip lever 17 about the coupling axis 18 results in the longitudinal end of the outer grip shell 16 facing away from the first longitudinal end 16a being pivoted out in the deployment direction and pivoted away from the longitudinal end of the main grip lever 17 facing away from the first longitudinal end 17a, as shown also from figure 4 is evident. In this position of the outer handle shell 16, an operator can reach behind the outer handle shell 16 and pull the entire handle 4 into the handling position, from where the vehicle door 2 can then be opened by a pivoting movement of the handle 4. During the pivoting movement to open the vehicle door 2, the vehicle opening means 6 designed as a Bowden cable (see, for example, figure 6 ) pulled by a lever-like Bowden cable driver 20 is pivoted about an axis of rotation 21. The pivoting movement of the spring-loaded Bowden cable driver 20 is brought about by the pivoting movement of the handle 4 at its second longitudinal end 12 in that a pin 23, which is movably mounted in a slot 22 and is fixedly fixed to the main handle lever 17, pivots the Bowden cable driver 20 when the main handle lever 17 is pivoted , whereby the vehicle opening means 6 towards the second longitudinal end 12 of the handle 4 is pulled.

So that the handle 4 for normal operation, ie for opening the vehicle door 2, does not assume the emergency operation position, in which the outer handle shell 16 is arranged pivoted relative to the main handle lever 17, thereby actuating the Bowden cable attached to the Bowden cable driver 6 would not be possible or only insufficiently possible for opening the vehicle door 2, a safety mechanism is provided in order to prevent a relative pivoting of the outer handle shell 16 and the main handle lever 17 in order to actuate the handle 4 during the door opening process. This backup mechanism is discussed below with reference to the Figures 11 to 16 described. The safety mechanism comprises a latching recess 24, which is formed on a second longitudinal end 16b of the outer handle shell 16, and a safety lever 25 which is pivotably mounted on the main handle lever 17 and has a latching hook 25a and which is designed to block a relative movement between the outer handle shell 16 and the main lever 17. The safety lever 25 is mounted pivotably about an axis 27 fixed to the main handle lever 17 and is urged by a spring element 26 into a position in which the latching hook 25a is in engagement with the latching recess 24, as is shown, for example, in figure 16 is shown. In this position, in which the locking hook 25a is disengaged from the locking recess 24, the handle 4 is arranged in its rest position, whereas in the handling position of the handle 4 the locking hook 25a is in engagement with the locking recess 24 (see, for example, figure 16 ). the figure 14 shows an arrangement in which the handle 4 is in the rest position and the grip plate 10 is in its home position. In this position, the locking hook 25a of the safety lever 25 is disengaged from the locking recess 24. In figure 15 an intermediate position is shown, in which the extension of the base plate 10 in the direction of the deployment direction 14 has begun, the handle 4 being arranged in a position between the rest position and the handling position and the base plate 10 being arranged between its basic position and its operating position. A lever arm 25b of the securing lever 25 applied to the latching hook 25a rests against a moving web 28, the force of the spring element 26 permanently affecting the lever arm 25b against the moving web 28 urges. The movement web 28 is formed on the handle support 9 so that when the base plate 10 moves, the lever arm 25b moves along the movement web 25 . In figure 15 the lever arm 25b has reached a position in which it rests against a slope 28a of the moving web 25. The bevel 28a is formed pointing away from the first longitudinal end 16a of the outer handle shell 16 . With further movement of the base plate 10, the bevel 28a makes it possible for the lever arm 25b to be able to rotate about the axis 27, with the lever arm 25b continuing to bear against the bevel 28a of the movement web 28. In this way, the locking hook 25a of the safety lever 25 moves into the locking recess 24, as shown in figure 16 is shown. In figure 16 the base plate 10 is in its ready position and the handle 4 is in its handling position, with the latching hook 25a of the safety lever 25 engaging in the latching recess 24 . Because the locking hook 25a is in engagement with the locking recess 24, movement of the grip shell 16 relative to the main grip lever 17 is blocked, so that in the handling position of the handle 4 movement into the emergency operating position is prevented. In general, it should be noted that the movement bar 28 is formed on the handle carrier 9 and the safety lever 25, which is not in engagement with the locking recess 24 when the handle 4 is in the rest position, is mounted on the main handle lever 17 so that it can pivot about the axis 27, with the movement bar 28 supporting the safety lever 25 during the movement of the handle 4 from the rest position into the handling position of the handle 4 pivoting about the axis 27 and in the handling position of the handle 4 the locking hook 25a is designed to bring the locking recess 24 into engagement.

Various embodiments directed to the movement of the base plate 10 from the home position to the ready position are described below. It is understood that the aspects of the previously described two-part handle 4 and the safety lever 25 are present in all three embodiments, even if it is not explicitly referred to below.

the Figures 17 to 20 show a first embodiment in which the drive element 8 is attached to the handle support 9 and drives a drive axle 29 in rotation. The drive axle 29 is non-rotatably connected to a rotary joint 30 . The rotary joint 30 itself is rotatably mounted on the handle support 9 and rotatably connected to a first longitudinal end 10a of the base plate 10 . In this way, the base plate 10 is movably mounted via the rotary joint 30 on the handle support 9 between the basic position and the ready position. At a second longitudinal end 10b of the base plate 10, this is rotatably connected to the handle support 9 via a further rotary joint 30, with the axis 31 of the second rotary joint 30 not being driven, but only the drive axis 29 being driven by the drive element 8 in order to rotate the base plate 10 from the in figure 14 shown basic position to move out towards the ready position. It goes without saying that a single rotary joint 30 can be sufficient, with the two rotary joints 30 used in the first embodiment ensuring very good stability and precise guidance of the base plate 10 and thus of the handle 4 . Like the Figures 17 to 20 can be seen, the rotary joints 30 are each lever-shaped. A respective first lever end 30a of the rotary joint 30 is rotatably connected to the base plate 10, whereas a second lever end 30b of the rotary joint 30 is both rotatably connected to the drive axle 29 and rotatably mounted on the handle support 9. More precisely, the rotary joints 30 are designed as angle levers, the lever arm 30c facing away from the first lever end 30a being connected to a control frame 32 (see FIG figure 17 ) is connected, which can be used to interact with a button to switch off, for example, the drive element 8 when the Base plate 10 has reached its ready position. The control frame 32 moves transversely to the deployment direction 14. The figure 18 shows the base plate 10 in its basic position, from which it is moved in the deployment direction 14. The base plate moves through an intermediate position in the figure 19 is shown before in her in figure 20 shown ready position has been reached. In the ready position of the base plate 10, the handle 4 is arranged in its handling position 4, in which an operator can pull on the handle 4 to open the door. The pulling movement is transmitted to the Bowden cable driver 20 and from there to the vehicle door opening means or the Bowden cable 6, whereby an actuating lever 33 coupled to the Bowden cable 6 and rotatably mounted on the handle support 9 is pivoted, whereby the vehicle door 2 is opened.

In the Figures 21 to 27 a second embodiment corresponding to the invention is shown, wherein the figure 21 shows the entire door handle assembly 3 according to the second embodiment, whereas FIG figure 22 the handle support 9 has been omitted for the sake of clarity. In the second embodiment, the base plate 10 is movably guided along guide rods 34 running transversely to the handle support 9 between the basic position and the ready position, as shown in FIG figure 23 can be seen, in which only the base plate 10, the handle 4 and the guide rods 34 are shown. In this case, the guide rods 34 are accommodated by corresponding through-holes formed in the base plate 10 and are provided with a sliding coating, so that the base plate 10 can be guided in a movable manner without major friction losses. The guide rods 34 are attached to the handle support 9 . A guide with only one guide rod or more than one guide rod would also be conceivable, with two guide rods 30 at the respective ends of the base plate 10 ensuring safe and stable guidance. The movement of Base plate 10 is a linear movement in the opening direction 14. The guide rods 30 are only used for guidance. The actual movement of the base plate 10 is in turn effected by the drive element 8 , which is coupled for movement to a drive lever 36 which is mounted on the handle support 9 such that it can rotate about a lever axis 35 . At its free end 37, the drive lever 36 has a drive pin 39, which is arranged within a slot 38 running transversely to the extension direction 14 and formed in the base plate 10 such that the drive element 8 moves the drive pin 39 via the drive lever 36 within the slot 38 and thereby the drive pin 39 urges the base plate 10 into its ready position (see for example Figures 24 to 27 ). Consequently, the movement of the base plate 10 takes place more or less according to the principle of a slotted guide. The constellation of drive lever 36, drive pin 39 and slot 38 is found at both longitudinal ends of the base plate 10, with only one drive lever 36 at one longitudinal end of the base plate 10 being driven by the drive element 8. The driven drive lever 36 is operatively connected to the other drive lever 36 via a coupling linkage 40 so that the driven drive lever 36 drives the other drive lever 36 via the coupling linkage 40 . The driving lever 36 is not driven directly by the driving element 8 . Rather, in normal operation, the drive element 8 drives a coupling lever 42 that is rotatable about an axis of rotation 41 . The coupling lever 42 is formed at its free end 43 with a coupling pin 44 which rests against the drive lever 36 during movement of the handle 4 from the rest position into the handling position and rotates it about its lever axis 35, as the Figures 24 to 27 show. while in figure 24 , which shows the rest position of the handle 4 and the ready position of the base plate 10, the coupling pin 44 is not yet in contact with the drive lever 36, When the drive element 8 is started up, the coupling pin 44 (see figure 25 ), which rotates the coupling lever 42 about the axis of rotation 41, comes into contact with the drive lever 36 and forces it about its lever axis 35, as a result of which the drive pin 39 in turn presses against the edge of the slot 38 and the base plate 10 is pushed in the outward direction 14, with the Base plate 10 can only move along the guide rods 34. In this way, the base plate 10 is moved along the guide rods 34, as the Figures 25 and 26 show. In figure 27 When the base plate 10 has reached its ready position, in which the handle 4 is arranged in its handling position and is ready to be actuated by an operator to open the vehicle door 2 . When the base plate 10 is in the ready position, the coupling pin 44 is arranged in the pin receptacle 45 formed on the drive lever 36 . When the coupling pin 44 is arranged in the pin receptacle 45, a movement of the base plate 10 beyond the ready position in the deployment direction 14 is blocked, as shown in FIG figure 27 is evident.

In the Figures 28 to 31 a third embodiment of the door handle arrangement 3 is shown, with the handle support 9 not being shown for reasons of clarity. The drive element 8 is arranged on the side of the base plate 10 and drives a toothed belt pulley 46 which in turn drives a toothed belt 47 . The toothed belt 47 runs parallel to the base plate 10 and drives two toothed belt pulleys 48 which are rotatably mounted on the handle support 9 . The two toothed belt pulleys 48 are each arranged at the longitudinal ends of the base plate 10 and are connected to a spindle element 49 in a rotationally fixed manner. The respective spindle elements 49 extend in the outward direction 14 and are each coupled to a spindle nut 50 which is attached to the base plate 10 in a torque-proof manner. would be conceivable also that the base plate 10 is only moved by a spindle element 9, in which case guide rods can then additionally be provided for guiding the movement. In general, the third embodiment is characterized in that the drive element 8 drives the toothed belt 48 and the base plate 10 is movably mounted on the handle support 9 via spindle elements 49 between the basic position and the ready position. The spindle elements 49 are connected in a torque-proof manner to the toothed belt pulleys 48 driven by the toothed belt 47 , the toothed belt pulleys 48 being rotatably mounted on the handle support 9 . The spindle elements 49 also interact with spindle nuts 50 attached to the base plate 10 so as to be non-rotatable. the Figures 29 to 31 show a the extension movement of the handle 4, wherein in figure 29 the handle 4 is in its rest position and the base plate 10 is in its home position, whereas in figure 30 Intermediate positions for the base plate 10 and the handle 4 are shown before both are moved by means of the toothed belt drive in the handling position or operating position.

In summary, a door handle arrangement 3 according to the present invention has been described above for three embodiments. The door handle arrangement 3 is used in a motor vehicle 1 and comprises - regardless of the embodiment - the handle support 9, the handle 4 and the drive element 8 attached to the handle support 9, wherein the handle 4 can at least assume the rest position and the handling position, and When installed in a vehicle door 2, the handle 4 is arranged to run flush with the outside 7 of the vehicle door 2 in the rest position and is arranged in a deployed direction 14 in the handling position for actuation relative to the outside 7 of the vehicle door 2. The invention is characterized in that a base plate 10 is movably mounted on the handle support 9, which is movable relative to the handle support 9 and on which the handle 4 is stored. The movement of the base plate 10 takes place during a movement from the basic position into the operating position in the deployment direction 14, with a return spring returning the base plate 10 to its basic position. The drive element 8 is coupled for movement to the base plate 10, with the drive element 8 also driving the base plate 10 in normal operation from a basic position, in which the handle 4 is arranged in its rest position, into a ready position, in which the handle 4 is arranged in its handling position , is designed to move. The handle 4 is moved into its handling position against the force of a restoring spring, which holds the handle 4 in its rest position and returns it to the rest position after actuation.

Further preferred embodiments according to the invention are described below, these embodiments relating to a door handle arrangement for a motor vehicle and the door handle arrangement having a handle support, a handle and a drive element, the handle being able to assume at least one rest position and one handling position, and the handle at installed in a vehicle door, in the rest position it is arranged to run flush with the outside of the vehicle door and in the handling position for actuation it is arranged set out in relation to the outside of the vehicle door in a raising direction, with a base plate being movably mounted on the handle support, which base plate can be moved relative to the handle support and on which the handle is mounted, and wherein the drive element is coupled for movement to the base plate and, in normal operation, the base plate moves from a basic position in which the handle is arranged in its rest position, into a ready position, in which the handle is arranged in its handling position, is designed to move.

Accordingly, in a further preferred embodiment it is provided that the drive element drives a drive axle in rotation and the base plate is mounted movably via at least one rotary joint on the handle support between the basic position and the ready position, the at least one rotary joint being non-rotatably connected to the drive axle. It is of course also conceivable for the base plate to be movably mounted at each of its two longitudinal ends via a respective rotary joint on the handle support, it being sufficient if one of the two rotary joints is drive-connected to the drive element and is driven by the drive element. The rotary joint has the advantage that the deployment movement of the handle is precisely defined and limited by the movement of the base plate. Pulling on the handle cannot raise the handle beyond its handling position because the base plate can only be moved in the raised direction as far as the rotary joint allows. Furthermore, only a pulling movement to open the vehicle door is possible, with the handle being pivoted relative to the base plate, but the base plate itself not being moved.

Accordingly, in the development of the further preferred embodiment, it is provided that the at least one rotary joint is lever-shaped and a first lever end of the rotary joint is rotatably connected to the base plate and a second lever end of the rotary joint is both rotatably connected to the drive axle and rotatably mounted on the handle support is. Due to this double function of the drive lever (rotatable mounting on the handle support and non-rotatable connection with the drive axle), the lever rotates around the axle on which it is driven at the same time, which reduces the space requirement.

According to an aspect of another further preferred embodiment is to move the base plate in their ready position is provided in that the drive element drives a toothed belt and the base plate is movably mounted on the handle support via at least one spindle element between the basic position and the ready position, the at least one spindle element being non-rotatably connected to a toothed belt pulley driven by the toothed belt. In this way, a very precise positioning of the base plate in its ready position and thus the handle in its handling position can be achieved.

For one configuration of the other further preferred embodiment, it is then provided that the toothed belt pulley is rotatably mounted on the handle support and the at least one spindle element interacts with a spindle nut that is non-rotatably attached to the base plate.

Finally, in the development of the other further preferred embodiment, it is provided that a spindle nut is attached in a rotationally fixed manner to one longitudinal end of the base plate and interacts with an associated spindle element which is rotationally fixedly connected to a toothed belt pulley rotatably mounted on the handle carrier. In this way it is ensured that both longitudinal ends of the base plate are moved uniformly and evenly, so that the handle is moved linearly transversely to the handle support into the handling position.

The invention described above is of course not limited to the embodiments described and illustrated. It is evident that numerous modifications can be made to the embodiments shown in the drawings, which would be obvious to a person skilled in the art, depending on the intended application, without thereby departing from the scope of the invention. The invention includes everything that is contained in the description and/or shown in the drawing, including anything that deviates from it of the concrete exemplary embodiments for the person skilled in the art.
