In the DE 102 17 488 B4 a device is described with a mountable from the inside of the door of the motor vehicle in the area of the door outer panel carrier. The carrier has a bearing pin for a bearing seat, which is located in a storage unit. Further, a handle is provided, with its first and second handle end with the pivotable about an axis Storage unit is coupled. The bearing unit is designed here as an over the entire length of the handle extending rocker. The assembly process of the handle to the rocker is done by a Einrenkbewegung with two movement phases. First, the handle is moved in a Einsteckphase perpendicular to the longitudinal direction of the rocker. Subsequently, the handle is moved in a displacement phase parallel to the longitudinal direction of the rocker. The first handle end of the handle here consists of a projecting pin which engages in a formed as a pin hole counter-coupling part of the rocker. Disadvantageously, the described phases of motion during assembly designed as expensive.

It is an object of the present invention to provide a device of the type mentioned, in which the disadvantages mentioned are avoided, in particular a device is provided, in which the assembly effort of the handle element can be kept low.

To solve this problem, a device having the features of claim 1 is proposed. In the dependent claims preferred developments are carried out.

For this purpose, the invention provides that the bearing unit is designed with a holding element spaced from the first axis, on which the first handle end is arranged, wherein the first handle end at least partially surrounds the holding element.

In contrast to the cited prior art, the bearing unit is simplified in its construction. At the same time the assembly effort is reduced, since only the first end of the handle without complicated movement phases, which are necessary in the prior art, must be guided to the holding element, wherein the first end of the handle such the holding element in a region of its cross-section that reliable positioning of the handle element on moving part is ensured. Advantageously, in the assembly of the handle element to the bearing unit, the first handle end on the holding element pivotally. This facilitates the assembly process of the handle element. After the first handle end is arranged on the holding element, in particular rests, can be achieved manually via a pivoting movement about the holding element, the final position of the handle element. Subsequently, for example, the second end of the handle can be positively and / or positively and / or firmly attached to the storage unit.

It is particularly advantageous that during assembly of the handle element, the first end of the handle is guided to the holding element and then the second handle end is moved to the storage unit via a pivoting movement of the handle member to the holding member to which the second end of the handle can be fastened. Advantageously, the holding element extends parallel to the first axis about which the bearing unit is pivotable. The bearing unit is in this case designed as a kind of "rocker", which moves inside the door as a "companion" of the handle. To keep installation costs low, the carrier can be prefabricated with the storage unit as a unit and attached to the inside of the moving part. Advantageously, the bearing unit is mounted free of play on the carrier.

In a preferred embodiment of the invention, the holding element with the storage unit forms a one-piece component. In this case, this component may be an injection molded part made of metal, in particular aluminum. Of course, a plastic material can be used alternatively.

In a particular embodiment of the device according to the invention, the holding element has at least one positioning means, whereby an improved horizontal mounting of the first handle end can be achieved. This can additionally be effected that an undesirable Kippbeweglichkeit the handle element is excluded. The positioning means causes the first handle end, in particular the handle element, to be held reliably in the horizontal position in each of its possible positions. Thus, unwanted friction during actuation of the grip element can be effectively avoided. While the user actuates the gripping element, according to the invention, the gripping element with the bearing unit around the first axis pivoted, wherein the first and the second end of the handle immovably, are fixed to the bearing unit, and mitverschwenkt together with the bearing unit about the first axis. Furthermore, the positioning means serves to fix the first handle end in the correct position on the holding element. In one possible embodiment of the invention, the positioning means may be formed by a groove formed on the holding element. The first end of the grip is hereby received by the groove, wherein the grip end abuts the Nutwandungen and thus a reliable horizontal storage of the first end of the handle is guaranteed.

It is particularly advantageous that there is a clearance fit between the handle end and the retaining element. In a particular embodiment of the device according to the invention, there is a zero fit between the first grip end and the retaining element. Since, during the actuation of the grip element, the bearing unit with the grip element simultaneously move about the first axis, no friction can arise between the first grip end and the retaining element and the second grip end and the bearing unit. Preferably, there is a backlash-free clamping of the first handle end on the holding element in the x, y and z-direction. As a result, undesired friction points can be avoided on the device according to the invention.

Advantageously, the first axis is formed by a pin on which the bearing unit is pivotally mounted. The one end of the bearing unit preferably forms a closed bearing on the first axis. Here, the pin may extend through bearing bores of the bearing unit, wherein the pin, which may be cylindrical, is attached at its free ends to the carrier.

A measure improving the invention can provide that the first end of the grip is open on one side as a slot, wherein the first end of the grip comprises the retaining element at least partially. The assembly effort of the arrangement of the first handle end on the holding element is thereby substantially simplified. Furthermore, tolerances, for example, in the injection molding of the relevant components, such as handle element, storage unit, ect. or which may arise in the event of temperature fluctuations, can be effectively compensated for via said slot at the first end of the grip. In a possible embodiment of the invention, the handle element is guided from the outside through openings of the movable part of the bearing unit in one of the last assembly steps, wherein a reliable fixing of the first and second handle end takes place on the storage unit. Preferably, this assembly takes place at defined temperatures. Subsequently, under normal conditions, in which high temperature fluctuations can occur, for example, expansions of the grip element arise. Since the first and the second handle end are respectively fixedly arranged on the bearing unit, no position changes can occur at these points due to temperature fluctuations, whereby a reliable operation of the device, in particular a reliable movement of the stylus element is ensured in a manual operation.

Furthermore, it can be provided that the unilaterally open region of the first handle end is aligned with the first axis. In this embodiment, the slot of the first end of the handle is held on the holding element of the bearing unit, wherein advantageously no additional fastening means for the handle element in the region of the first handle end is necessary.

In a further alternative, the unilaterally open region of the first handle end is aligned with the interior of the motor vehicle. In this case, it may make sense to additionally secure the grip element in the region of the first grip end positively and / or non-positively and / or cohesively on the retaining element. During the assembly process, for example, the first end of the handle can be fastened to the holding element via additional latching elements.

It is particularly advantageous that an outlet leading to the closure is provided on the bearing unit and / or on the grip element. Upon actuation of the grip element, the closure of the movable part of the motor vehicle is actuated via the outlet, in particular opened when an unlocking position is present in the closure. Also, the lock cylinder of the device according to the invention may be connected to an additional outlet, which acts upon actuation of the lock cylinder on the closure and this locks or unlocked. The departure can be realized for example via a Bowden cable.

Alternatively, a rotatably mounted on a second axis of rotation coupling element may be provided, on which a closure leading to the outlet acts and the coupling element is in operative connection with the bearing unit. Upon actuation of the grip element, the bearing unit is simultaneously pivoted about the first axis, wherein the bearing unit moves the coupling element, whereby the outlet is moved via the coupling element. Preferably, the bearing unit with the handle element from a first position to a second position and vice versa pivoted. The first position is the rest position. In the second position of the handle element, an actuation of the closure is triggered for opening the movable part, wherein the handle element has been previously moved by a defined angular range from the movable part about the first axis of rotation. The bearing unit preferably contacts a first stop element in its first position. In the second position, the bearing unit in the second position can touch a second stop element. The abovementioned stop elements can be integrated, for example, on the stationary carrier.

In a particular embodiment, a spring element is provided which is in operative connection with the coupling element and the bearing unit, wherein in the second position of the bearing unit, the spring element exerts such a restoring force that the bearing unit is independently movable to its first position. The coupling element may preferably be designed with a receptacle in which the outlet is held. The departure can be attached at its one end form and / or force and / or cohesive to said recording.

So that in the event of a side impact, an actuation of the closure as well as an opening of the movable part, in particular of the vehicle door, does not occur, at least one mass balance weight is integrated in the device according to the invention. A particularly compact design is achieved in that the mass balance weight is integrated on the coupling element.

Furthermore, it can be provided that the device according to the invention is monitored by control electronics. For safety reasons, it may be advantageous be, if in addition to the detection of the position of the bearing unit and the positions of the handle element or the coupling element are detected. This can be done, for example, via sensors, in particular magnetic field sensors, which detect the magnetic field of a permanent magnet attached to the coupling element, to the bearing unit or to the grip element.

In Fig. 1 to 4 a device 10 according to the invention for actuating a closure of a motor vehicle door 12 is shown. The device 10 has a fixed support 11 which is fixed to the inside of the movable door 12. At the left portion of the carrier 11, a first axis 13 is provided, on which a bearing unit 20 is pivotally mounted. The bearing unit 20 is as a kind of rocker executed. As 3 and 4 make clear, the handle member 40 has a first and a second handle end 41, 42, wherein the second handle end 42 is attached to the free end 23 of the bearing unit 20.

The bearing unit 20 is designed with a holding element 24 spaced from the first axis 13, on which the first handle end 41 is arranged, the first handle end 41 at least partially surrounding the holding element 24. In the present embodiment of the invention, in this case the first handle end 41 is open on one side as an elongated hole, wherein the first handle end 41 with its slot comprises the first axis 13 at least partially. The first axis 13 has a pin 13 a, which is arranged on the left region of the carrier 11. The bearing unit 20 is pivotally mounted about the pin 13a, wherein the pin 13a extends through bores of the bearing unit 20, not shown.

In the present embodiment, there is a clearance fit between the first handle end 41 and the support member 24. When the user operates the handle member 40, as in FIG Fig. 2 and 4 is indicated, the bearing unit 20 is pivoted about the first axis 13 about the second end of the handle 42. Since the bearing unit 20 and the grip element 40 move in parallel, there is no relative movement between the two named components 20, 40, so that no friction between the two components 20, 40 can take place.

It is particularly advantageous that during assembly of the grip element 40 to the bearing unit 20, the first handle end 41 on the holding element 24 is pivotable. Here, in the assembly process of the handle element 40, the first handle end 41 is guided to the holding element 24, and then the second handle end 42 is moved about a pivoting movement of the handle member 40 to the support member 24 to the bearing unit 20, then the second handle end 42 is attached. This may be, for example, a positive and / or positive and / or cohesive connection. In the illustrated embodiment, the second handle end 42 is connected via a screw connection 25 to the bearing unit 20, which is not explicitly shown.

As in Fig. 1 to Fig. 4 can be seen, the holding element 24 extends parallel to the first axis 13. Here, the holding element 24 forms with the bearing unit 20 is a one-piece component. The retaining element 24, which is provided as a kind of connecting strut within the construction of the bearing unit 20, forms a one-piece component with the bearing unit 20. In addition, the holding member 24 serves as a reinforcement in the storage unit 20. In the 3 and 4 It can be clearly seen that the unilaterally open region of the first handle end 41 is aligned with the first axis 13. This means that the slot of the first handle end 41 faces the first axis 13.

In a further alternative of the invention, the unilaterally open area of the first handle end 41 may be aligned with the interior of the motor vehicle, which in Fig. 6 is shown in schematic representation. According to this embodiment Fig. 6 In addition, a screw connection 25 is provided which fixes the first handle end 41 on the holding element 24 reliably. In contrast, according to Fig. 1 to Fig. 4 no additional fastening means necessary to fix the first handle end 41 on the holding element 24.

Furthermore, in Fig. 1 to 4 an outlet leading to the closure 14 is shown. In the present embodiment, the outlet 14 is provided on a coupling element 30 which is rotatably mounted on a further axis of rotation 15, wherein the coupling element 30 is in operative connection with the bearing unit 20. In another embodiment, not shown, the outlet 14 leading to the closure may be provided on the bearing unit 20 or on the grip element 40 or even on the stationary support 11. As in Fig. 2 can be seen, the bearing unit 20 has an end face 21 which faces the handle member 40. Further, the pivotable about the second axis of rotation 15 coupling element 30 is formed with a contact portion 31 on which the end face 21 acts during the movement of the bearing unit 20.

As the 3 and 4 illustrate, the bearing unit 20 with the handle member 40 from a first position (see Fig. 3 ) to a second position (see Fig. 4 ) and vice versa pivoted. The first position is the rest position. During the movement from the first position to the second position, the outlet 14 is actuated, whereby a not explicitly shown closure of the motor vehicle can be opened when an unlocking position already exists in the closure. In this way, the vehicle door 12 opens. The outlet 14 is a Bowden cable in the present embodiment, which extends to the closure. The outlet 14 is held on a receptacle 33 which forms the same material with the coupling element 30 a common component which is movable about the second axis of rotation 15. The roller-like receptacle 33 is designed with a groove 33a in which the outlet 14, in particular the Bowden cable, is guided and held. Upon actuation of the grip element 40, the bearing unit 20 is pivoted about the first axis of rotation 13. At the same time, the end face 21 presses against the contact region 31 of the coupling element 30, as a result of which the coupling element 30 rotates about the second axis of rotation 15. During the movement of the bearing unit 20, the contact region 31 of the coupling element 30 rolls on the end face 21. In the first position of the storage unit 20 according to Fig. 1 and 3 , the contact region 31, which bears against the end face 21 of the bearing unit 20, has a defined distance from the second rotation axis 15. While the coupling element 30 rotates about the second axis of rotation 15, the receptacle 33 also moves in the same direction of rotation, wherein the Bowden cable 14 is wound on the receptacle 33 by a certain amount. This creates a tensile force on the outlet 14, which acts directly on the closure.

As in 3 and 4 is clarified, the carrier 11 is attached to the pivotable bearing unit 20 on the inside of the door 12. The grip element 40 is attached only later to the rocker 20 and to the first axis 13, and from the outside of the door 12 from. As in Fig. 1 to Fig. 4 can be clearly seen, the carrier 11 has a first and a second stop element 16a, 16b. The bearing unit 20 rests with its right area in its first position on the first stop element 16a.

Furthermore, the device according to the invention has a spring element 32, which is in operative connection with the coupling element 30 and the bearing unit 20. The spring element 32 exerts in the second position of the bearing unit 20 such a restoring force that the bearing unit 20 is automatically in its first position according to Fig. 1 emotional. In the present embodiment, the coupling element 30 has a pin 35, on which the spring element 32 is attached (see Fig. 2 ).

The coupling element 30 is further formed with two mass balance weights 34, which are moved during the movement of the bearing unit 20 from the first to the second position about the second axis of rotation 15. These mass balance weights 34 serve to prevent the bearing unit 20 from being accidentally pushed into its second position in the event of a side impact due to the centrifugal forces that occur, as a result of which an undesired opening operation of the door 12 would be triggered. In this case, the mass balance weights 34 counteract the centrifugal forces acting, so that a movement of the bearing unit 20 about the first axis of rotation 13 in the direction of the second position is excluded.

In Fig. 5 a further embodiment of the invention is shown, wherein the holding element 24 has at least one positioning means 22, whereby a horizontal mounting of the first handle end 41 can be achieved. The positioning means 22 is formed by a groove 24 a formed on the holding element 24. The groove 24a takes in this case the first handle end 41 reliably. The remaining arrangement of the device according to the invention substantially corresponds to the embodiment according to Fig.1 to Fig. 4 , While the handle member 40 is actuated by the user, the bearing unit 20 pivots about the rotation axis 13, the groove 24a holding the first handle end 41 in its horizontal position.

The carrier 11 is further designed with an opening 36 in which a lock cylinder (not shown) is inserted into the carrier 11 and fastened there. Also, the lock cylinder may have a departure, which acts upon actuation of the lock cylinder on the closure and this locks or unlocked.
