In this case, the electrical opening can be done before reaching an end position of the handle 4. In the case of a power-driven

Normal operation thus extends a slight pulling movement of the Handle 4, so that an example indicated in Figure 1 Bowden cable system 7 for unlocking the door lock 5 is electrically operated. In the case of a powerless emergency operation, the door handle assembly 3 may be formed such that a manual unlocking of the door lock 5 and thus a manual opening of the vehicle door 2 by an operator effected actuation of the handle 4 is possible, in which case the handle 4 on the im normal operation necessary deflection must also be deflected or actuated. FIG. 2 shows a perspective view of one of the vehicle doors 2 and the handle 4 serving to open the vehicle door 2. In FIG. 2, the handle 4 is in the case of installation of the door handle assembly 3 in the

Vehicle door 2 - approximately flush with the outer contour 8 of the vehicle door 2, i. flush, arranged. In this position, the handle 4 is in a non-use position in which it is not needed. From that shown in FIG

Motor vehicle 1 is arranged, wherein the handle 4 is engaged behind by an operator. The handle 4 is thus moved parallel in the operating position compared to the non-use position and with respect to the outer contour 8 of

Vehicle door 2 arranged above and can be operated by the operator to open the vehicle door 2. To couple the handle 4 to the vehicle door 2 is a frame-like

trained handle carrier 9 is provided, which is shown schematically and dashed lines only in Figure 3, since it is arranged on the inside of the vehicle door 2 and thus in Figures 1 and 2 hidden from the vehicle door 2. The handle support 9 is fixed on the inside of the vehicle door 2 via known fastening means and supports the handle 4. In other words, the handle support 9 which can be fastened to the vehicle door 2 serves

As is known, the attachment and storage of the handle 4 and is fastened by means not shown screw on the inside of the door 2.

FIGS. 5 to 12 show various embodiments of the door handle arrangement 3 according to the invention, FIGS. 5 and 6 showing a first embodiment, FIGS. 7 to 10 a second embodiment and FIGS. 11 and 12 a third embodiment. Common to all three embodiments is that a first longitudinal end 10 of the handle 4 mounted on the handle 9 is coupled for movement with a first lever mechanism 11 and a second longitudinal end 12 of the handle 4 is coupled for movement with a second lever mechanism 14. In this case, the first lever mechanism 11 in all three embodiments, a first pivot axis 15 which is fixedly arranged on the handle support 9, wherein the first pivot axis 15 may alternatively be arranged on the vehicle door 2. Due to the

fixed attachment to the handle support 9 or alternatively to the vehicle door 2 is for the first pivot axis 15 in the Figures used the mechanical symbol of a fixed camp.

Furthermore, the first lever mechanism 11 has a first hinge axis 16, which is arranged on the first longitudinal end 10 of the handle 4 and which is coupled for movement with the first pivot axis 15. Here, the first hinge axis 16 is mounted on the handle 4, so that the first hinge axis 16 in a movement of the handle 4 from the non-actuating position in the

Actuating position is moved with the handle 4. Furthermore, in all three embodiments, the second lever mechanism 14 on a second pivot axis 17 which is fixedly arranged on the handle support 9 or alternatively on the vehicle door 2, which is why a mechanical bearing for the second pivot axis 17 exemplarily a fixed bearing is used in the figures. The second pivot axis 17 also includes a second

Joint axis 18 which is arranged at the second longitudinal end 12 of the handle 4 and which is moved with a movement of the handle 4 with the handle 4, wherein the second hinge axis 18 is coupled in motion with the second pivot axis 17. In all embodiments shown in the figures, the second comprises

Lever mechanism 14 further comprises a first coupling lever 19 and a second coupling lever 20. The first coupling lever 19 is pivotally mounted on the second pivot axis 17, whereas the second coupling lever 20 is rotatably connected to the second hinge axis 18. Furthermore, the second lever mechanism 14 has a connecting joint 21, which is movable relative to the handle 4 and to the handle support 9. The connecting joint 21 connects the first coupling lever 19 rotatably with the second coupling lever 20. In the non-use position of the handle 4, the first coupling lever 19 and the second coupling lever 20 at the connecting joint 21 at an acute angle 22, ie an angle of less than 90 ° to each other arranged (see Figures 5, 7 and 11), whereas in the operating position of the handle 4, the first coupling lever 19 and the second

Coupling lever 20 at the connecting joint 21 under a obtuse angles 23, ie an angle between 90 ° and 180 °, are arranged relative to one another (see FIGS. 6, 8 and 12). Consequently, the first coupling lever 19 and the second coupling lever 20 are spread when the handle 4 from their

Non-use position moved to its operating position. As can also be seen from the figures for the various embodiments, the second pivot axis 17 is the first one

Coupling lever 19, the second coupling lever 20, the second hinge axis 18 and the connecting joint 21 disposed within a longitudinal extent 24 of the handle 4, wherein the

Connecting joint 21 between the first pivot axis 15 and the second pivot axis 17 is arranged lying. The

Longitudinal extent 24 of the handle 4 corresponds to the length of the handle 4 in a longitudinal direction 25 of the handle 4, as shown in the figures. Finally, everyone is

Common to embodiments that the connecting joint 21 of the second lever mechanism 14 is connected via a coupling linkage 26 with the first lever mechanism 11 and is coupled for movement. Accordingly, in a movement of the handle 4 from the non-use position to the operating position the

Coupling linkage 26, the connecting joint 21 in the direction of the second pivot axis 17 designed to be moving. In other words, the coupling linkage 26 urges the connecting joint 21 in

Direction of the second pivot axis 17 to move the handle 4 from the non-use position to the operating position.

In the three embodiments, a connecting lever 53 is provided on the handle 4, which end to the first

Joint axis 16 and the second hinge axis 18 is rotatably mounted. The connecting lever 53 is purely optional and serves to a certain degree of stabilization.

Before the different designs of the first

Lever mechanism 11 are described below, the alternatives shown in Figures 9 and 10 for a

Embodiment of the second coupling lever 20 addressed. The FIGS. 9 and 10 each show a position of the handle 4 in which the handle 4 has been actuated out of the operating position by an operator and has therefore assumed a position in which the handle 4 is inclined relative to the handle

Longitudinal direction 25 is arranged. Upon actuation of the handle 4, therefore, embodiments according to FIGS. 9 and 10 are conceivable by which the handle 4 is moved further out of the vehicle door 2 at its second longitudinal end 12 than at its first longitudinal end 10, which may be necessary, for example, in the case of a mechanical emergency actuation to manually operate the Bowden cable system 7. For this purpose, it is conceivable that the second coupling lever 20 has two lever portions 20a and 20b, which are hingedly connected to each other via an intermediate joint 20c. In the non-use position and the

Actuating position, the two lever portions 20a and 20b extend in line, so that a straight-line coupling lever is given, as shown for example in Figures 7 and 8. On the other hand, the intermediate joint 20c allows the two lever sections 20a, 20b to be pivoted relative to each other on the intermediate joint 20c when the handle 4 is in the

Operation position is operated by an operator, as shown in Figures 9 and 10.

The above description for the configuration of the second lever mechanism 14 has for all in the figures

shown embodiments, wherein below the existing specific to the individual embodiments are described. It should be noted that within the meaning of the invention the expression "rotatably connected to one another" means an articulated connection of two elements, so that the two elements are freely rotatable relative to one another but nevertheless coupled to one another on a joint element.

From Figures 5 and 6, which are based on the first

Embodiment of the door handle assembly 3 relate is to

recognize that the first lever mechanism 11 diamond-shaped is trained. Correspondingly, the first lever mechanism 11 has a first diamond lever 27, a second diamond lever 28, a third diamond lever 29 and a fourth diamond lever 30, wherein the first diamond lever 27 and the second diamond lever 28 are rotatably mounted on the first pivot axis 15 and the third diamond lever 29 and the fourth diamond lever 30 are rotatably supported on the first hinge axis 16. Further, the first diamond lever 27 and the third diamond lever 29 are rotatably connected to each other via a first diamond joint shaft 31, whereas the second diamond lever 28 and the fourth diamond lever 30 are rotatably connected to each other via a second diamond joint axis 32. To form the diamond shape, the first pivot axis 15 and the first hinge axis 16 are opposite in a direction transverse to the longitudinal direction 25 of the handle 4 direction

arranged. The coupling linkage 26 is further connected to the first rhombic joint axis 31, wherein the coupling linkage of the second diamond joint axis 32 in the longitudinal direction 25 of the handle 4 is movably guided. Here are the first

Rautengelenkachse 31 and the second diamond joint axis 32 in the longitudinal direction 25 and move towards each other when the handle 4 from the non-actuated position in the

Actuating position is moved.

As can be seen from FIG. 5, FIGS

Non-use position of the handle 4 both the first

Diamond lever 27 and the second diamond lever 28 at the first

Pivot axis 15 and the third diamond lever 29 and the fourth diamond lever 30 at the first hinge axis 16 at an obtuse angle 33 to each other (in Figure 5, the obtuse angle 33 is shown for reasons of clarity only at the first hinge axis 16), whereas in the

Non-use position of the handle 4 both the first

Diamond lever 27 and the third diamond lever 29 at the first

Rautengelenkachse 31 and the second diamond lever 28 and the fourth diamond lever 30 on the second diamond joint axis 32 under an acute angle 35 are arranged to each other (in Figure 5, the acute angle 35 is shown for reasons of clarity only on the second diamond joint axis 32). For reasons of clarity, only the obtuse angle 33 on the first articulation axis 16 and the acute angle 35 on the second rhombic articulation axis 32 are shown in FIG.

In Fig. 6 showing the operating position of the handle 4, both the first diamond lever 27 and the second diamond lever 28 on the first pivot axis 15 and the third diamond lever 29 and the fourth diamond lever 30 on the first

Joint axis 16 at an acute angle 34 to each other

are arranged (in Figure 6, the acute angle 34 for reasons of clarity, only on the first hinge axis sixteenth

whereas, the first diamond lever 27 and the third diamond lever 29 on the first diamond joint axis 31 and the second diamond lever 28 and the fourth diamond lever 30 on the second diamond joint axis 32 are disposed at an obtuse angle 36 to each other (in Fig. 6, the obtuse angle 36 for reasons of clarity only at the first

Rautengelenkachse 31 marked).

As can also be seen in FIGS. 5 and 6 for the first embodiment, the first lever mechanism 11 is arranged both in the non-use position and in the actuation position of the handle 4 within the longitudinal extent 24 of the handle 4, the second diamond-shaped hinge axis 32 being between the first rhombic hinge axis 31 and the connecting joint 21

is arranged. When the handle 4 in a current-driven normal operation of the door handle assembly 3 from that in Figure 5

shown non-use position is moved to the operating position shown in Figure 6, for example, engages only in Figure 5 exemplarily drawn

Drive element 37 on the first diamond joint axis 31 and moves the first diamond joint axis 31 in the direction of the second lever mechanism 14. The guided by the coupling rod 26 second Rhombic hinge axis 32 moves in opposite directions to the first

Rautengelenkachse 31, wherein the first diamond joint axis 31 and the second diamond joint axis 32 to move toward each other when the drive member 37, the handle 4 of the

Non-use position moved to the operating position. During the movement of the handle 4, the diamond-shaped first lever mechanism 11 is compressed, with the first diamond lever 27 and the third diamond lever 29 pivoting about the first diamond joint axis 31 and the second diamond lever 28 and the fourth diamond lever 30 about the second diamond joint axis 32. In this case, the first diamond lever 27 and the third diamond lever 29 move toward the second diamond lever 28 and the fourth diamond lever 30, so that the diamond levers 27, 28, 29, 30 move the first hinge axis 16 perpendicular to the longitudinal direction 25, whereby the handle 4 gets into the issued operating position. Furthermore, the compression of the diamond levers 27, 28, 29, 30 and in particular the movement of the first diamond joint axis 31 causes the coupling linkage 26 moves in the direction of the second lever mechanism 14, whereby the first coupling lever 19 and the second

Coupling lever 20 are spread. By this spreading, the second hinge axis 18 also moves perpendicular to the

Longitudinal direction 25, so that the handle 4 is moved out of the outer contour 8 at its second longitudinal end 12 and the handle 4 in total in the one shown in Figure 6

Operating position is arranged. The return movement of

Handle 4 back to the non-use position takes place in reverse order.

Figures 7 and 8 show a second embodiment, which differs from the first embodiment by the configuration of the first lever mechanism 11, wherein the second

Lever mechanism 14 identical to the first embodiment

is trained. In the second embodiment, the first lever mechanism 11 has a guide lever 38 and a movement lever 39. The movement lever 39 is rotatable with the first Joint axis 16 and rotatable with a on the handle support 9 (or alternatively on the vehicle door 2) linearly movable

Motion axis 40 is connected. Furthermore, the guide lever 38 is rotatably mounted on the first pivot axis 15, wherein the
