Description

The invention relates to a door handle arrangement and a movement arrangement for a door handle arrangement.

Door handle arrangements with a recessed door handle, in particular for vehicles, in particular for vehicle doors, are generally known from the prior art. In these door handle arrangements, in order to enable the vehicle door to be opened, the door handle is driven by an electric motor and is extended from a position recessed in the vehicle door into a use position. After opening the vehicle door, the door handle is retracted into the lowered position by an electric motor.

The object of the present invention is to provide a door handle arrangement which is improved compared to the prior art and a movement arrangement for such a door handle arrangement which is improved compared to the prior art.

The object is achieved according to the invention by a door handle arrangement with the features of claim 1 and a movement arrangement with the features of claim 10.

Advantageous embodiments of the invention are the subject of the subclaims.

A door handle arrangement according to the invention, in particular an outside door handle arrangement, is provided for a door, in particular for a vehicle door. It comprises a door handle that can be moved from a lowered position into a use position. The door handle is moved, for example, electrically, in particular by means of an electric motor. By actuating and / or touching the door handle is to open the door. In normal operation, this takes place after the door handle is arranged in the use position. I.e. the door handle is first moved from the recessed position, in particular recessed in the door, into the use position, in particular moved out of the door, in which it is easily accessible for actuation and / or contact. For example, an emergency release can also be provided for emergency operation, for example in the event of a failure of the electrical power supply or due to some other cause, so that the door handle can no longer be moved into the use position. In this case it can be provided, for example, that the door handle can also be actuated and / or touched accordingly in the lowered position to open the door.

The door handle arrangement further comprises a return spring, in particular for returning the door handle from the use position to the lowered position or to at least support this return.

For this purpose, the return spring is coupled to the door handle, for example directly to the door handle or via a connecting lever connected to the door handle, and in the recessed position and in the use position to an at least then fixed counter-bearing, for example directly or via a spring tensioning lever. For example, a spring leg or at least one spring leg of the return spring is coupled to the door handle or to the connecting lever, is in particular on it, and the other spring leg or at least one other spring leg of the return spring is coupled to the counter bearing or with the spring tensioning lever, is in particular on, in particular in such a way that a relative movement of the connecting lever and the spring tensioning lever in one direction would or would tension the return spring increasingly and the tension would or would be increasingly relaxed in the other direction. The restoring spring serves in particular for a coupling, in particular an elastic coupling, of the connecting lever and spring tensioning lever and thus a coupling, in particular an elastic one Coupling of the door handle and the spring tensioning lever, for example to enable anti-trap protection, in particular when moving into the lowered position.

The return spring is decoupled from the counter bearing between the sunk position and the use position.

For example, it can additionally be provided that the counter-bearing assumes a retracted counter-bearing position in the recessed position and an extended counter-bearing position in the use position and can be transferred from the retracted counter-bearing position to the extended counter-bearing position while moving the door handle from the recessed position into the use position, with it then advantageously covers a movement path, for example the same movement path, in the same time as the door handle and / or, if present, its connecting lever.

In particular, the spring tensioning lever on which the return spring rests, and thus also the return spring, is decoupled from the counter bearing between the recessed position and the use position, the spring tensioning lever advantageously being moved along with the door handle and thus with the return spring.

This solution ensures that the return spring is no longer tensioned by moving the door handle from the recessed position into the use position, but the counter bearing and thus the leg of the return spring supported on it is moved in the direction of the use position and / or the return spring due to the lack of contact with the counter bearing during the movement into the use position is no longer tensioned, but remains, for example, in its tensioned state or, for example, something, but not completely, is relaxed. This places an additional load on a drive, in particular the electric motor, for moving the door handle into the Avoided use position because the drive, in particular the electric motor, only has to move the door handle and does not have to additionally tension the return spring, ie does not have to work against the spring action of the return spring and thus does not have to do any further spring work. The drive, in particular the electric motor, thus has a greater power reserve and / or, for example, a smaller drive, in particular an electric motor, can be used, whereby advantages in terms of installation space are achieved. Without this solution, the return spring would be additionally tensioned each time the door handle is moved into the use position, which results in unnecessary losses in the drive and increases wear on the drive and the return spring and thus shortens the service life. The solution described avoids this, reduces wear and tear and increases the service life.

In one possible embodiment, the door handle arrangement comprises a spring tensioning lever and an eccentric unit. The return spring is coupled to a spring contact area of the spring tensioning lever. The eccentric unit is rotatably mounted and has a spring tensioning lever eccentric curve for guiding the spring tensioning lever. The spring tensioning lever eccentric curve is designed in such a way that the spring tensioning lever rests against the spring tensioning lever eccentric curve in the lowered position of the door handle and in the use position of the door handle and is spaced apart from the spring tensioning lever eccentric curve in between.

The eccentric unit forms the counter-bearing for the return spring, which is coupled to the eccentric unit via the spring tensioning lever in the lowered position and the use position. The eccentric unit is arranged on a component of the door handle arrangement, for example on a bearing bracket, which is fixed, or at least fixed, when the door handle is in the lowered position and in the use position. The door handle arrangement is fastened or can be fastened to the door via this bearing bracket.

This ensures that the return spring is no longer tensioned by moving the door handle from the recessed position into the use position, but the counter bearing and thus the leg of the return spring supported on it is moved in the direction of the use position and / or the return spring due to the during the movement into the use position with no contact to the counter bearing is no longer tensioned, but remains, for example, in its tensioned state or, for example, something, but not completely, is relaxed.

In one possible embodiment, the return spring is part of a movement arrangement, in particular for moving the door handle from the recessed position into the use position and back. This movement arrangement comprises the connecting lever coupled, in particular pivotably coupled, to the door handle, in particular to an end region of the door handle, the spring tensioning lever, the return spring and the eccentric unit. As already mentioned, the eccentric unit forms the counter-bearing for the return spring, which in the recessed position and the use position is coupled to the eccentric unit via the spring tensioning lever. As already mentioned, the eccentric unit is arranged on a component of the door handle arrangement, for example on the bearing bracket, which is fixed, at least fixed when the door handle is in the lowered position and in the use position. The door handle arrangement is fastened or can be fastened to the door via this bearing bracket.

The connecting lever and the spring tensioning lever are advantageously mounted pivotably about a common pivot axis and pivotable relative to one another about this pivot axis. The return spring is advantageously coupled to a spring contact area of the connecting lever and to the spring contact area of the spring tensioning lever, in particular with a respective spring leg, that it is activated by a pivoting movement of the spring contact area of the spring tensioning lever in the direction of the spring contact area of the connecting lever can be relaxed and tensioned by an opposite pivoting movement. As already described, the return spring is coupled via the spring tensioning lever to the eccentric unit forming the counter-bearing in the recessed position and the use position, so that the spring tensioning lever is then immovable and thus, for example, also keeps the connecting lever and thus also the door handle immovable due to the bias of the return spring . In this way, for example, a rattling of the door handle is avoided, in particular in the lowered position.

The eccentric unit is rotatably mounted, for example rotatably mounted on the bearing bracket, and advantageously has a connecting lever eccentric curve for guiding the connecting lever and the spring tensioning lever eccentric curve for guiding the spring tensioning lever. These eccentric cams are advantageously arranged in two different planes, so that the eccentric unit has two eccentric disks, which are arranged one above the other and are fixed to one another or formed in one piece, each with one of the eccentric cams.

The eccentric curves are advantageously designed such that

• by rotating the eccentric unit, the movement arrangement can be transferred from a retracted position, in which the door handle is positioned in the lowered position, into an extended position, in which the door handle is positioned in the use position,
• advantageously, the connecting lever and the spring tensioning lever are positioned relative to one another in the retracted position and the extended position in such a way that the return spring is partially tensioned,
• advantageously the connecting lever rests against the connecting lever eccentric curve during the rotary movement of the eccentric unit, expediently also in the retracted position and the extended position, and
• the spring tension lever in the retracted position and the extended position Position rests on the spring tensioning lever eccentric curve and is spaced between them from the spring tensioning lever eccentric curve.

The connecting lever can thus be pivoted by means of the connecting lever eccentric curve around the pivot axis from a connecting lever initial position (retracted position of the movement arrangement) into a connecting lever end position (extended position of the movement arrangement). In the retracted position of the movement arrangement, the spring tensioning lever is in a tensioning lever initial position, the spring contact areas of the spring tensioning lever and connecting lever being advantageously spaced apart from one another in such a way that the return spring is pretensioned, i.e. slightly tensioned, in particular in such a way that it rests firmly against the two spring contact areas and thus does not rattle. In the extended position of the movement arrangement, the spring tensioning lever is in a tensioning lever end position, with the spring contact areas of the spring tensioning lever and connecting lever again being spaced apart from one another in such a way that the restoring spring is pretensioned, that is, slightly tensioned, in particular such that it rests firmly against the two spring contact areas and thus does not rattle. In the initial tension lever position and the final tension lever position, the spring tension lever rests against the spring tension lever eccentric curve. In between, that is, between the initial tension lever position and the final tension lever position, and thus during the movement into the extended position and thereby during the movement of the door handle into the use position, the spring tension lever is spaced from the spring tension lever eccentric curve, i.e. it no longer rests on it and can therefore freely move around the Pivot the swivel axis. Due to the restoring spring between the spring tensioning lever and the connecting lever, which has been pretensioned up to that point, the spring contact area of the spring tensioning lever approaches the spring contact area of the connecting lever while releasing the restoring spring and is then pivoted together with the connecting lever and the return spring due to the connection via the return spring. This takes place until the connecting lever has reached the connecting lever end position and the Spring tensioning lever again rests against the spring tensioning lever eccentric curve, by means of which it is moved into its tensioning lever end position, whereby the spring contact areas are again spaced from one another, in such a way that the return spring is biased again. During the movement, the return spring is thus decoupled from the counter bearing formed by the eccentric unit and is not tensioned, in particular not additionally tensioned.

The eccentric unit and / or the pivot axis are advantageously arranged on the bearing bracket and are thus immovable components, with the exception of the rotation of the eccentric unit, i. H. the eccentric unit itself is fixed in position, it only rotates, in particular on a drive axle which is arranged in the bearing bracket, so that the eccentric curves move accordingly. The eccentric unit thus forms, as already described above, the counter bearing for the return spring. The spring tensioning lever and connecting lever move by pivoting about the pivot axis.

The eccentric unit is advantageously arranged in a fixed manner on the drive axle or formed in one piece with it and can be rotated by rotating the drive axle. The drive of the door handle to move it into the use position is thus carried out via the eccentric unit.

As already mentioned, the eccentric unit is advantageously arranged on the bearing bracket via the drive shaft, which is rotatably mounted in the bearing bracket. As a result, as already mentioned, it is arranged in a fixed position on the bearing bracket and thus forms the counter-bearing for the return spring. The position of the counter bearing is changed by turning the eccentric unit, whereby the spring tensioning lever rests on different areas of the spring tensioning lever eccentric curve.

The movement arrangement, in particular the connecting lever, is advantageously coupled to a further movement arrangement which is connected to is coupled to the other end region of the door handle, in particular is pivotably coupled. As a result, both end regions of the door handle can be moved by means of a single drive unit, so that the door handle can be moved from the lowered position into the use position, for example by parallel displacement. For this purpose, a force transmission rod is advantageously arranged between the movement arrangement, in particular its connecting lever, and the further movement arrangement.

A movement arrangement according to the invention for the door handle arrangement described above comprises the connecting lever for connection to the door handle, the spring tensioning lever, the return spring and the eccentric unit, the connecting lever and the spring tensioning lever being pivotably mounted about the common pivot axis and being pivotable relative to one another about this pivot axis, the The return spring is coupled to the spring contact area of the connecting lever and to the spring contact area of the spring tensioning lever in such a way that it can be relaxed by the pivoting movement of the spring contact area of the spring tensioning lever in the direction of the spring contact area of the connecting lever and tensioned by the opposite pivoting movement, the eccentric unit being rotatably mounted and the connecting lever eccentric curve to Has leadership of the connecting lever and the spring tensioning lever eccentric curve for guiding the spring tensioning lever, and wherein the eccentric curves are designed such that

• by turning the eccentric unit, the movement arrangement can be transferred from the retracted position to the extended position,
• the connecting lever and the spring tensioning lever are positioned relative to one another in the retracted position and the extended position such that the return spring is partially tensioned,
• the connecting lever rests on the connecting lever eccentric cam during the rotary movement of the eccentric unit and
• the spring tension lever in the retracted position and the extended position Position rests on the spring tensioning lever eccentric curve and is spaced between them from the spring tensioning lever eccentric curve.

This achieves the advantages already outlined above. The door handle arrangement advantageously comprises such a movement arrangement as already described above.

The connecting lever eccentric curve is advantageously designed in such a way that the connecting lever rests against a first connecting lever contact section in the retracted position and against a second connecting lever contact section of the connecting lever eccentric curve in the extended position, the first connecting lever contact section in particular having a smaller distance from the drive axis than the second connecting lever contact section, with the The first connecting lever contact section has the smallest distance between the connecting lever eccentric curve and the drive axis and the second connecting lever contact section has the greatest distance between the connecting lever eccentric curve and the drive axis. This enables the increasing movement, in particular pivoting, of the connecting lever and thus the increasing extension of the door handle into the use position.

The spring tensioning lever eccentric curve is advantageously designed in such a way that the spring tensioning lever rests against a first spring tensioning lever contact section in the retracted position and against a second spring tensioning lever contact section of the spring tensioning lever eccentric curve in the extended position. In particular, the first spring tensioning lever contact section has a greater distance from the drive axis than the second spring tensioning lever contact section, with the first spring tensioning lever contact section having the greatest distance between the spring tensioning lever eccentric curve and the drive axis and the second connecting lever contact section having the smallest distance Has spring tension lever eccentric curve to the drive axis. This ensures that the spring tensioning lever eccentric curve rests against the spring tensioning lever pivoted with the connecting lever in the tensioning lever end position. Thus, in the initial tensioning lever position, ie in the retracted position of the movement arrangement and thus in the lowered position of the door handle assembly and thus of the door handle, the first spring tensioning lever contact section of the spring tensioning lever eccentric curve of the eccentric unit forms the counter bearing for the spring tension lever and thus for the return spring, the counter bearing thus being in the retracted counter bearing position, and in the clamping lever end position, ie in the extended position of the movement arrangement and thus in the use position of the door handle arrangement and thus the door handle, the second spring tensioning lever contact section of the spring tensioning lever eccentric curve of the eccentric unit forms the counter bearing for the spring tensioning lever and thus for the return spring, whereby the counter bearing is now in the extended counter bearing position by turning the eccentric unit.

In one possible embodiment, the spring tensioning lever has a recess for the implementation of the first spring tensioning lever contact section during the rotary movement of the eccentric unit. As a result, the greatest possible rotational movement of the eccentric unit is made possible in order to achieve the greatest possible movement path of the door handle.

The connecting lever has, for example, a roller for rolling on the connecting lever eccentric curve of the eccentric unit. This enables a low-friction and low-wear movement of the connecting lever and thus of the door handle, so that only a small amount of force is required for the drive unit and a long service life is achieved. As already mentioned above, an electric motor is advantageously provided as the drive unit for rotating the eccentric unit. This enables the door handle to be moved electrically into the use position and back.

As already mentioned above, the eccentric unit is advantageously fixedly arranged on the drive axle or formed in one piece with it and rotatable by rotating the drive axle. The drive axle is then advantageously coupled to the electric motor, in particular via a gear, in particular via a worm gear, crown gear, bevel gear or toothed gear. This enables a force deflection and / or a translation or reduction, for example.

The Figures 1 to 7 show a movement arrangement 1 for a door handle arrangement 2 and the Figures 8 and 9 the door handle arrangement 2 with such a movement arrangement 1. The movement arrangement 1 is shown in FIG Figure 1 in a retracted position, in Figure 2 in an intermediate position and in Figure 3 shown in an extended position. The Figures 4 to 7 again show another representation of the movement arrangement 1, also here in FIG Figure 4 in the retracted position, in Figure 5 in an intermediate position, in Figure 6 in a further intermediate position and in Figure 7 is shown in the extended position. The door handle assembly 2 is shown in FIG Figure 8 shown in a retracted position in which the movement assembly 1 is in the retracted position, and in Figure 9 shown in a use position in which the movement assembly 1 is in the extended position.

The door handle arrangement 2 is designed in particular as an outside door handle arrangement. It is intended for a door, in particular for a vehicle door. It comprises one that can be moved from the lowered position into the use position Door handle 3. The door handle 3 is moved, for example, electrically, in particular by means of an electric motor (not shown here).

The door can be opened by actuating and / or touching the door handle 3. In normal operation, this takes place after the door handle 3 is arranged in the use position. I.e. the door handle 3 is first moved from the recessed position, in particular recessed in the door, into the use position, in particular extended out of the door, in which it is easily accessible for actuation and / or contact.

For example, an emergency release can also be provided for emergency operation, for example in the event of a failure of the electrical power supply or due to some other cause, so that the door handle 3 can no longer be moved into the use position. In this case it can be provided, for example, that the door handle 3 can also be actuated and / or touched accordingly in the lowered position for opening the door.

The door handle arrangement 2 further comprises a return spring 4, in particular for returning the door handle 3 from the use position to the lowered position or to at least support this return.

For this purpose, the return spring 4 is coupled to the door handle 3, for example directly to the door handle 3 or, as in the example shown here, via a connecting lever 5 connected to the door handle 3, and in the lowered position and in the use position with an at least then fixed counter bearing G coupled, for example directly or, as in the example shown here, via a spring tensioning lever 6. For example, a spring leg 4.1 or at least one spring leg 4.1 of the return spring 4 is coupled to the door handle 3 or, as in the example shown here, is coupled to the connecting lever 5 in particular to it, and the other spring leg 4.2 or at least one other spring leg 4.2 of the return spring 4 is with the counter bearing G or, as in here shown example, with the spring tensioning lever 6 and via this at least in the recessed position and in the use position coupled to the counter bearing G, this other spring leg 4.2 rests on the spring tensioning lever 6, in particular in such a way that a relative movement of the connecting lever 5 and spring tensioning lever 6 in one direction the return spring 4 is increasingly tensioned or would be tensioned and in the other direction is increasingly relaxed or would be relaxed. The return spring 4 is used in particular to couple, in particular an elastic coupling, of the connecting lever 5 and spring tensioning lever 6 and thus a coupling, in particular an elastic coupling, of the door handle 3 and spring tensioning lever 6, for example to provide anti-trap protection, in particular when moving into the lowered position to enable.

The return spring 4 is used in particular to entrain the door handle 3, more precisely the connecting lever 5 and thus the door handle 3, during the movement back into the recessed position. For this purpose, for example, the spring tensioning lever 6 is moved and, through the spring tension of the return spring 4, takes along the door handle 3, which is coupled to the spring tensioning lever 6 via the return spring 4, more precisely the connecting lever 5, which is coupled to the spring tensioning lever 6 via the return spring 4, and thus also the door handle 3 .

The return spring 4 is decoupled from the counter-bearing G between the recessed position and the use position and / or the counter-bearing G assumes a retracted counter-bearing position in the recessed position and an extended counter-bearing position in the use position and is out of the recessed position while the door handle 3 is being moved into the use position from the retracted counter-bearing position into the extended counter-bearing position, whereby it then advantageously covers a movement path in the same time as the door handle 3 and / or, if available, its connecting lever 5. In particular, the spring tensioning lever 6, on which the return spring 4 is applied, and thus also the return spring 4 itself, decoupled from the counter bearing G between the lowered position and the use position, as in FIG Figure 2 and Figure 5 is shown and will be described in more detail below, wherein the spring tensioning lever 6 is advantageously moved with the door handle 3 and thus with the return spring 4.

This solution ensures that the return spring 4 is no longer tensioned by moving the door handle 3 from the recessed position into the use position, but the counter bearing G and thus the spring leg 4.2 of the return spring 4 supported on it is also moved in the direction of the use position, and / or the return spring 4 is no longer tensioned due to the lack of contact with the counter bearing G during the movement into the use position, but instead remains, for example, in its tensioned state or, for example, somewhat, but not completely, relaxed. This avoids additional loading of a drive, in particular the electric motor, for moving the door handle 3 into the use position, since the drive, in particular the electric motor, only has to move the door handle 3 and does not have to additionally tension the return spring 4, i.e. H. does not have to work against the spring action of the return spring 4 and thus does not have to perform any further spring work. The drive, in particular the electric motor, thus has a greater power reserve and / or, for example, a smaller drive, in particular an electric motor, can be used, whereby advantages in terms of installation space are achieved. Without this solution, the return spring 4 would be additionally tensioned each time the door handle 3 is moved into the use position, which results in unnecessary losses in the drive and increases wear on the drive and the return spring 4 and thus shortens the service life. The solution described avoids this, reduces wear and tear and increases the service life.

The Figures 1 to 9 show a possible embodiment for realizing the solution described. Here, the return spring 4 is part of the Movement arrangement 1, in particular for moving the door handle 3 from the lowered position into the use position and back. This movement arrangement 1 comprises the connecting lever 5, which is coupled to the door handle 3, in particular to an end region of the door handle 3, in particular is pivotably coupled, as in FIG Figures 8 and 9 shown, as well as the spring tensioning lever 6, the return spring 4 and an eccentric unit 7. The movement arrangement 1 with its components and the mode of operation of the movement arrangement 1 is shown in FIG Figures 1 to 7 is shown in detail and is described in more detail below.

The eccentric unit 7 forms the part of the movement arrangement 1 driven by the drive unit, in particular the electric motor, and in turn drives the connecting lever 5 in particular to pivot it and thereby move the door handle 3 into the use position. It is rotatably mounted for this purpose, for example on a bearing bracket of the door handle arrangement 2. For this purpose, it is fixedly arranged on a drive shaft 8 and rotatably mounted on the bearing bracket by means of this drive shaft 8, ie. H. the drive shaft 8 is rotatably mounted on the bearing bracket. The drive axle 8 and via this the eccentric unit 7 is coupled to the drive, in particular to the electric motor, for example via a worm gear or some other gear.

The eccentric unit 7 forms the counter-bearing G for the return spring 4, which is coupled to the eccentric unit 7 via the spring tensioning lever 6 in the lowered position and the use position. The eccentric unit 7 is arranged on the bearing bracket and thus on a component of the door handle arrangement 2 which is fixed, at least fixed when the door handle 3 is in the lowered position and in the use position. The door handle arrangement 2 is fastened or can be fastened to the door via this bearing bracket.

The connecting lever 5 and the spring tensioning lever 6 are mounted pivotably about a common pivot axis 9 and relative to this pivot axis 9 pivotable to each other. The pivot axis 9 is also arranged in the bearing bracket and is therefore fixed in relation to the bearing bracket. The return spring 4 is coupled to a spring contact area 10 of the connecting lever 5 and to a spring contact area 11 of the spring tensioning lever 6, in particular with a respective spring leg 4.1, 4.2, that it is activated by a pivoting movement of the spring contact area 11 of the spring tensioning lever 6 in the direction of the spring contact area 10 of the connecting lever 5 can be relaxed and tensioned by an opposite pivoting movement. As already described, in the recessed position and the use position, the return spring 4 is coupled via the spring tensioning lever 6 to the eccentric unit 7 forming the counter bearing G, so that the spring tensioning lever 6 is then immobile and thus, for example, the connecting lever 5 and thus also the door handle 3 due to the bias of the return spring 4 keeps immobile. In this way, for example, a rattling of the door handle 3 is avoided, in particular in the lowered position.

The eccentric unit 7 rotatably mounted by means of the drive shaft 8 and driven by the drive, in particular the electric motor, has a connecting lever eccentric curve 12 for guiding the connecting lever 5 and a spring tensioning lever eccentric curve 13 for guiding the spring tensioning lever 6. These eccentric cams 12, 13 are arranged in two different planes, so that the eccentric unit 7 has two eccentric disks, which are arranged one above the other and are fixed to one another or formed in one piece, each with one of the eccentric cams 12, 13.

• by rotating the eccentric unit 7 shown in FIG Figures 2 , 5 , 6th and 8th by a first movement arrow P1, the movement arrangement 1 can be transferred from the retracted position, in which the door handle 3 is positioned in the lowered position, into the extended position, in which the door handle 3 is positioned in the use position, as in FIG Figure 8 by a die Movement of the door handle 3 is shown illustrating the second movement arrow P2,
• the connecting lever 5 and the spring tensioning lever 6 are positioned relative to one another in the retracted position and the extended position in such a way that the return spring 4 is partially tensioned,
• the connecting lever 5 rests against the connecting lever eccentric curve 12 during the rotary movement of the eccentric unit 7, expediently also in the retracted position and the extended position, and
• the spring tensioning lever 6 in the retracted position and the extended position, in particular with a contact section 17, rests against the spring tensioning lever eccentric curve 13 and is spaced apart from the spring tensioning lever eccentric curve 13 in between. The contact section 17 of the spring tensioning lever 6 is in particular spaced apart from the spring contact area 11 of the spring tensioning lever 6, in particular arranged at a different end of the spring tensioning lever 6 than the spring contact area 11.

The connecting lever 5 is thus by means of the connecting lever eccentric curve 12 about the pivot axis 9 from a connecting lever initial position (retracted position of the movement arrangement), shown in FIG Figure 1 and Figure 4 in a connecting lever end position (extended position of the movement arrangement), shown in Figures 3 and 7th , swiveling, as in the Figures 2 , 5 , 6th and 8th shown by means of a third movement arrow P3. In the retracted position of the movement arrangement 1, the spring tensioning lever 6 is in an initial tensioning lever position ( Figures 1 and 4th ), the spring contact areas 11, 10 of the spring tensioning lever 6 and connecting lever 5 being spaced from one another in such a way that the return spring 4 is pretensioned, ie slightly tensioned, in particular in such a way that it rests firmly against the two spring contact areas 11, 10 and thus does not rattle. This is in the Figures 1 and 4th shown by the spaced apart spring contact areas 10, 11, between which there is a gap.

In the extended position of the movement arrangement 1, the spring tensioning lever 6 is in a tensioning lever end position ( Figures 3 and 7th ), whereby advantageously the spring contact areas 11, 10 of the spring tensioning lever 6 and connecting lever 5 are again spaced apart from one another in such a way that the return spring 4 is pretensioned, ie slightly tensioned, in particular in such a way that it rests firmly against the two spring contact areas 11, 10 and thus does not rattle . This is in the Figures 3 and 7th by the spring contact areas 10, 11 which are again spaced apart from one another and between which there is a gap.

In the initial tension lever position and the final tension lever position, the spring tension lever 6 rests against the spring tension lever eccentric curve 13, as in FIG Figures 1 and 3 as well as 4 and 7 are shown. In between, that is, between the initial tension lever position and the final tension lever position and thus during the movement into the extended position and thereby during the movement of the door handle 3 into the use position, the spring tension lever 6 is spaced from the spring tension lever eccentric curve 13, ie it no longer rests against it and can therefore Pivot freely about the pivot axis 9, corresponding to the direction of the third movement arrow P3, as in FIG Figures 2 as well as 5 and 6 , which show intermediate positions of the movement arrangement 1.

Due to the previously pre-tensioned return spring 4 between the spring tensioning lever 6 and connecting lever 5, the spring contact area 11 of the spring tensioning lever 6 approaches the spring contact area 10 of the connecting lever 5 while releasing the return spring 4 and, for example, comes into contact with it, as in FIG Figure 2 as well as in the Figures 5 and 6th due to the now closed gap between the contact areas 11, 10 of the spring tensioning lever 6 and connecting lever 5, and is then pivoted together with the connecting lever 5 and the return spring 4 due to the connection via the return spring 4. This takes place until the connecting lever 5 has reached the connecting lever end position and the spring tensioning lever 6 rests again on the spring tensioning lever eccentric curve 13 through which it is in its Tensioning lever end position is moved, whereby the spring contact areas 10, 11 are again spaced apart, in such a way that the return spring 4 is biased again, as in Figure 3 and Figure 7 shown. During the movement, the return spring 4 is therefore decoupled from the counter bearing G formed by the eccentric unit 7 and is not tensioned, in particular not additionally tensioned.

The connecting lever eccentric curve 12 is designed in such a way that the connecting lever 5 is in the retracted position ( Figure 1 and Figure 4 ) on a first connecting lever contact section 12.1 and in the extended position ( Figure 3 and Figure 7 ) rests against a second connecting lever contact section 12.2 of the connecting lever eccentric curve 12, the first connecting lever contact section 12.1 being at a smaller distance from the drive shaft 8 than the second connecting lever contact section 12.2. In particular, the first connecting lever contact section 12.1 has the smallest distance between the connecting lever eccentric curve 12 and the drive axis 8 and the second connecting lever contact section 12.2 has the greatest distance between the connecting lever eccentric curve 12 and the drive axis 8. This enables the increasing movement, in particular pivoting, of the connecting lever 5 and thus the increasing extension of the door handle 3 into the use position, as in the comparison of FIG Figures 1 and 3 , compared to the Figures 4 and 7th as well as in comparison of the Figures 8 and 9 to recognize. By rotating the eccentric unit 7, the connecting lever 5 slides or rolls along the connecting lever eccentric curve 12 from its first connecting lever bearing section 12.1 to its second connecting lever bearing section 12.2 and is increasingly pivoted about the pivot axis 9 due to the shape of the connecting lever eccentric curve 12 and its increasing distance from the drive axis 8, ie increasingly deflected from the connecting lever initial position, in which the door handle 3 is arranged in the recessed position, into the connecting lever end position, in which the door handle 3 is arranged in the use position, the door handle is moved by means of the connecting lever 3 moving in this way from the lowered position into the use position.

The spring tensioning lever eccentric curve 13 is designed such that the spring tensioning lever 6 rests on a first spring tensioning lever contact section 13.1 in the retracted position and on a second spring tensioning lever contact section 13.2 of the spring tensioning lever eccentric curve 13 in the extended position. The first spring tension lever contact section 13.1 is at a greater distance from the drive shaft 8 than the second spring tension lever contact section 13.2. In particular, the first spring tensioning lever contact section 13.1 has the greatest distance between the spring tensioning lever eccentric curve 13 and the drive axis 8, and the second connecting lever contact section 13.2 has the smallest distance between the spring tensioning lever eccentric curve 13 and the drive axis 8. This ensures that the spring tensioning lever eccentric curve 13 rests on the spring tensioning lever 6 pivoted with the connecting lever 5 in the tensioning lever end position. Thus, in the initial tensioning lever position, ie in the retracted position of the movement arrangement 1 and thus in the lowered position of the door handle assembly 2 and thus the door handle 3, the first spring tensioning lever contact section 13.1 of the spring tensioning lever eccentric curve 13 of the eccentric unit 7 forms the counter bearing G for the spring tensioning lever 7 and thus for the Return spring 4, as in Figures 1 and 4th shown, whereby the counter bearing G is thus in the retracted counter bearing position, and in the tensioning lever end position, ie in the extended position of the movement arrangement 1 and thus in the use position of the door handle assembly 2 and thus the door handle 3, the second spring tensioning lever abutment section 13.2 forms the spring tensioning lever eccentric curve 13 of the eccentric unit 7, the counter bearing G for the spring tensioning lever 6 and thus for the return spring 4, as in the Figures 4 and 7th shown, the counter bearing G by turning the eccentric unit 7, it is now in the extended counter-bearing position.

The spring tensioning lever 6 advantageously has a recess for the implementation of the first spring tensioning lever contact section 13.1 during the rotary movement of the eccentric unit 7. This enables the greatest possible rotational movement of the eccentric unit 7 in order to achieve the greatest possible movement path of the door handle 3. The implementation of the first spring tensioning lever contact section 13.1 through this recess of the spring tensioning lever 6 is shown in FIG Figure 3 and Figure 7 recognizable, the recess being here on a rear side of the spring tensioning lever 6 facing the eccentric unit 7. This enables the eccentric unit 7 to be rotated by, for example, 360 ° and thereby in particular achieves a particularly long connecting lever eccentric curve 12 for moving the connecting lever 5, which can thus be achieved, for example, with little effort.

In the example shown, the connecting lever 5 has a roller 14 for rolling on the connecting lever eccentric curve 12 of the eccentric unit 7. This enables a low-friction and low-wear movement of the connecting lever 5 and thus the door handle 3, which means that only a small amount of force is required for the drive unit, in particular the electric motor, and a long service life is achieved.

As in Figure 8 and Figure 9 As shown, the movement arrangement 1, in particular the connecting lever 5, is coupled to a further movement arrangement 15 which is coupled to the other end region of the door handle 3, in particular is pivotally coupled. As a result, both end regions of the door handle 3 can be moved by means of a single drive unit, for example by means of a single electric motor, so that the door handle 3 is moved from the lowered position into the use position, for example by parallel displacement can be as compared to the Figures 8 and 9 recognizable. For this purpose, a force transmission rod 16 is arranged between the movement arrangement 1, in particular its connecting lever 5, and the further movement arrangement 15 and is connected to the movement arrangement 1, in particular with its connecting lever 5, and the further movement arrangement 15, so that the two movement arrangements 1, 15 are coupled to one another are.

The door handle 3 is moved into the recessed position, for example, by means of the spring tensioning lever 6, in particular by moving it by means of the eccentric unit 7 and the spring tensioning lever eccentric curve 13, in particular by turning the eccentric unit 7 in the opposite direction to moving the door handle 3 into the use position. The spring tensioning lever 6 pivots as a result about the pivot axis 9 back, ie in the opposite direction to moving the door handle 3 into the use position. The return spring 4 is used in particular to take along the door handle 3, more precisely the connecting lever 5 and thus the door handle 3. The spring tensioning lever 6 takes the door handle 3 coupled via the return spring 4 to the spring tensioning lever 6, more precisely the one via the spring tension of the return spring 4 the return spring 4 with the spring tensioning lever 6 coupled connecting lever 5 and thereby also the door handle 3, with which the door handle 3 is moved back into the lowered position.
