In the EP 10 191 475 discloses a handle of a motor vehicle, which is designed with a movably mounted balance weight (13.1), which is mounted on a support (12) such that it can move about an axis of rotation (13.4). The balance weight (13.1) is spring loaded by a return spring (11.1). Spaced to the balance weight (13.1) is a receptacle (13.2) for a Bowden cable provided. A shaft, which is movable about the axis of rotation (13.4), connects the balance weight (13.1) with the receptacle (13.2). This embodiment has been reinforced by its excellent operation. However, the vehicle industry calls for further measures to reduce the assembly effort of such a well-functioning handle. In the US 2005/161959 A1 is a handle of a motor vehicle with the features of the preamble of claim 1 disclosed.

The object of the present invention is to avoid the abovementioned disadvantages, in particular to provide a handle which has low production and assembly costs, while ensuring good functionality. To solve this problem, a handle with all the features of claim 1 is achieved. In the dependent claims preferred developments are carried out. It is envisaged that the recording with the balance weight and the shaft form a common monolithic functional component. Since the recording with the balance weight and the shaft forms a one-piece functional component, the assembly process can be significantly simplified. The number of components is simultaneously reduced, so that the manufacturing costs of the handle according to the invention can be greatly reduced. Preferably, the recording with the balance weight and the shaft is made of the same material, which means that the functional component may be homogeneous in all areas, that is on the recording, the balance weight and on the shaft of the same material. In order to ensure a satisfactory stability of the carrier, which is preferably made of a plastic, the carrier according to the invention a plurality of walls, wherein a wall separates the balance weight of the recording and a wall has a fastening device, the captive the functional component on the carrier holds. In one possible embodiment of the invention, the functional component is an injection-molded part made of plastic. It is also conceivable that the functional component may be a two-component or a three-component or multi-component component, wherein the receptacle and the balance weight may be injection-molded onto the shaft and thus the receptacle, balance weight and shaft made of different materials, in particular plastic materials and / or metal materials could be.
The balance weight used in this inventive handle has the function of the acting acceleration forces that can act on the handle element in an accident to compensate. Here, the handle element, the movable on movable part, in particular on the motor vehicle door, is mounted, in a possible embodiment, a kind of finger, which is in operative connection with the balance weight. In an accident, the balance weight acts as a backup, which effectively counteracts the acceleration forces on the door handle, to prevent accidental opening of the vehicle door. In addition, a crash barrier can be integrated with the handle, which locks the door handle, for example, in its rest position as a nimble lock. In a possible embodiment of the invention, the balance weight may be multi-part, wherein a support member may be provided, to which a weight is attached. The support element with the weight forms the balance weight. In this case, the carrier element with the receptacle and the shaft form the monolithic functional component. Alternatively, the weight with the receptacle and the shaft form a monolithic functional component.
Advantageously, the functional component is formed by the carrier element, by the shaft and by the receptacle, wherein the monolithic functional component is an injection molded part made of plastic. The weight is attached to the carrier element, wherein the weight is expediently made of metal.
In a measure improving the invention it can be provided that the weight is positively and / or positively and / or materially secured to the carrier element, in particular that a clip connection holds the weight on the carrier element. For example, it is conceivable that locking elements are integrally formed on the carrier element, which engage in counter-locking elements of the weight, in order to thus ensure a simple assembly and a reliable attachment of the weight to the carrier element. Alternatively and / or additionally, there may be a positive connection between the weight and the carrier element. The fastening device can be designed in several parts and at least one locking connection have, in particular, an irreversibly releasable attachment for the functional component. After the functional component is inserted in the carrier, the final fixation of the functional component takes place with the aid of the fastening device.

For example, it is conceivable that the weight is metallic and / or the carrier element is metallic and / or the weight and the carrier element are a common monolithic component, in particular form the balancing weight.

It is also possible that the carrier has a plurality of bearing points on which the functional component is movably mounted. Advantageously, the bearings are distributed along the extension of the functional component on the carrier, so that a satisfactory rotational movement of the functional component is ensured at an actuation of the handle element at the bearings. The bearings may also be configured such that the functional component can not fall out of the carrier, since the bearings reliably hold the functional component in the mounting position. This can for example be realized in that a first and / or a second wall has a projection-like and / or circular segment-like bearing, in particular the orientation of the bearing of the first wall is opposite to the orientation of the bearing of the second wall. The opposite orientation of the bearings in this case aims that the functional component reliably maintains its mounting position on the carrier.

In a further measure improving the invention it can be provided that the fastening device has an opening through which the functional component with the shaft extends. Advantageously, the opening of the geometry of the shaft of the functional component is adapted.

After the functional component has been inserted into the carrier during the assembly process, in a further step, the closure part is introduced into the channel of the wall. In the assembled position of the closure member, the fastening device effectively prevents the functional component from dislodging from the carrier. At the same time, the locking part for the shaft provides a suitable bearing point to ensure a satisfactory rotational movement about the axis of rotation.

It is also possible that the functional component with a bearing point of the carrier forms a tongue and groove connection, wherein in particular the tongue and groove connection has a projection on the functional component, which extends into a recess of the bearing. Here, the functional component is located between two outer walls of the carrier, wherein the distance between the two outer walls may be greater than the elongate extent of the functional component. As a result, a simplified assembly of the functional component is realized in the carrier. The functional component can be inserted vertically from above onto the defined location of the carrier, wherein only one side of the functional component contacts a wall of the carrier. The opposite second end of the functional component, however, is spaced from the facing wall of the carrier. Subsequently, the functional component is linearly displaced along its extension to the wall, to which the functional component is spaced with its free end. During the movement of the functional component, a tongue and groove connection is created between a bearing point of the carrier and the functional component. Only then is the mounting position of the functional component achieved. Subsequently, the closure part can be fastened to a wall of the carrier.

In addition, it is conceivable for the functional component to have a rib element which extends through the opening of the fastening device, wherein the closure part has such a circular segment-like opening that the rib element can move in the opening during a movement of the functional component about the axis of rotation, wherein in particular the rib element is aligned parallel to the axis of rotation of the functional component and the projection is aligned transversely to the axis of rotation. It has been found that the rotational safety of the functional component can be substantially increased at the bearing points of the carrier. At the same time, the material stiffness on the functional component can be increased to the projection due to the inventive arrangement of the rib element.

In a further measure of the invention, the functional component may be spring loaded, wherein in particular a torsion spring acts on the functional component such that, after an actuation of the grip element from a rest position into an actuating position, the grip element automatically moves into its rest position due to the spring loading. In addition, the torsion spring may have a central region which acts on a web of the carrier and two free ends of the torsion spring are supported on the functional component. This special arrangement of the torsion spring on the functional component, in particular in the region of the balance weight further favors the assembly of the functional component on the carrier. During the assembly process of the functional component, it is only necessary that the central region of the spring is to be fastened to the fixed web of the carrier. The web may, for example, run below or above the counterweight and have an engagement area which is arranged to be easily accessible to the central region of the torsion spring. The central portion of the torsion spring can be attached via a simple movement of the torsion spring on the attack area of the web.

In the various figures of the drawing, like parts are always provided with the same reference numerals. The description applies to all drawing figures in which the corresponding part can also be recognized.

FIG. 1 shows a carrier 10 of a handle 1 of a motor vehicle, which schematically in FIG. 10 is attached to a motor vehicle. The carrier 10 according to FIG. 1 is hereby arranged on the inside of the movable door 2 of the motor vehicle. Further, in the carrier 10, a functional component 30 is arranged, which has a receptacle 35, a balance weight 32, 33 and a shaft 31. The receptacle 35 is designed with the balance weight 32, 33 and the shaft 31 as a one-piece functional component 30. The receptacle 35 has a groove 40, in which a force transmission element 36 extends, which with a lock 3 (s. Fig. 10 ) of the door 2 is in operative connection.

The handle 1 further comprises a handle element 4 according to FIG. 10 , which acts on an attack area 17 of the functional component 30. If now the user moves the grip element 4 from a rest position (unactuated position) into an actuating position, the grip element 4 exerts a force on the engagement region 17, so that the functional component 30 with the receptacle 35, the balance weight 32, 33 and the shaft 31 a rotation axis 5 moves. About the movement of the receptacle 35 about the axis of rotation 5, the force transmission element 36 exerts a corresponding force on the lock 3, which can trigger, for example, a locking operation, unlocking the lock 3 and / or an opening operation of the door 2. The power transmission element 36 may, for. B. be a Bowden cable.

The functional component 30 is in the present embodiment, an injection molded part made of plastic, wherein the balance weight 32, 33 has a support member 33 to which a weight 32 is attached made of metal. According to FIG. 6 and FIG. 7 The carrier element 33 has latching elements 39, which can be resilient. The weight 32 is designed with corresponding recesses 41 as counter-locking elements. In addition, the carrier element 33 is formed with a slot-shaped opening 42 into which an elongate projection 43, which is adapted to the geometry of the opening 42, is insertable. In the fastened state of the weight 32 on the support member 33, the projection 43 is positively held in the opening 42 of the support member 33, wherein additionally hold the locking elements 39 in the counter-locking elements 41, the weight 32 on the support member 33 laterally captive.

For better clarity is in FIG. 1 . 3 and 9 the weight 32 "hatched from lower left to upper right", wherein the support member 33, the shaft 31 and the receptacle 35 "are hatched from top left to bottom right".

As in FIG. 1 can be clearly seen, the carrier 10 a plurality of walls 11, 12, 13, wherein a wall 12, the balance weight 32, 33 separates from the receptacle 35. The wall 12 according to FIG. 1 is executed with a fastening device 20, the captive the functional component 30 holds on the carrier 10, which will be discussed below. The fastening device 20 can alternatively also be arranged on one of the side walls 11, 13, which in FIG FIG. 9 is shown as an example. The operation of the fastening device 20 according to FIG. 1 and according to FIG. 9 is the same. In the following, the operation of the fastening device 20, however, the example according to FIG. 1 and FIG. 2 described. In FIG. 2 it can be seen that the fastening device 20 is designed in several parts. Here, the fastening device 20 has a closure part 23 which is guillotinenartig inserted into a channel 15 of the wall 12. Laterally, the closure member 23 on resilient locking elements 21, which enter into a fully engaged state of the closure member 23 is a latching connection with the wall 12. The locking elements 21 are designed with corresponding surfaces 21 a, which are inclined such that in the inserted state of the closure part 23 a destructive pulling or loosening of the closure member 23 from the channel 15 of the wall 12 is no longer possible.

The wall 12 and the closure part 23 have openings 18, 22, through which the shaft 31 extends. After the functional component 30 has been inserted into the carrier 10 during assembly, a final fixation of the functional component 30 takes place by means of the closure part 23, which is introduced into the channel 15 of the wall 12 in a guillotine fashion as described above until the closure part 23 in the wall 12 is engaged.

The carrier has according to FIG. 2 and FIG. 4 a plurality of bearings 14a, 14b, 14c, 14d, on which the functional component 30 is movably mounted. The bearing points 14a, 14d, which are arranged on the first and the second wall 11, 13, have a circular segment-like geometry. According to FIG. 2 and FIG. 4 In this case, the bearing 14a is open upwards and the bearing 14d opened downwards. Thus, both bearings 14a, 14d are aligned opposite to each other. During assembly, it should be noted that initially one end of the functional component 30 is inserted obliquely into the carrier 10, the first contacting with the functional component 30 taking place in the region of the bearing point 14d. Subsequently, the other end of the functional component 30 is tilted to bearing point 14a until the functional component 30 reliably abuts against all bearing points 14a, 14b, 14c, 14d.

The shaft 31, which connects the balance weight 32, 33 with the receptacle 35, is located in the bearing 14 b. The functional component 30 has end shaft pieces 44, 45, which are contacted at the bearing points 14a, 14d.

In a further embodiment of the invention, it is conceivable that the functional component 30 is designed in the region of the shaft 31 with a projection 37 (s. Fig. 8 ). The carrier 10, however, is executed at the bearing 14 b with a recess 19. The extent of the recess 19 and the projection 37, which is designed like a rib, extends in the present embodiment, transverse to the longitudinal direction of the functional component 30. The embodiment according to FIG. 8 serves as a mounting relief. Here, the distance between the walls 11 and 13 is greater than the longitudinal extension of the functional component 30. The functional component 30 can in this case perpendicular to the carrier 10th are inserted, first the one shaft piece 45, the wall 11 contacted. The shaft 44, however, has a significant distance from the wall 13. In this position of the functional component 30, the projection 37 rests on the bearing point 14d. If the functional component 30 is then moved a little linearly in the direction of the wall 13, the projection 37 is moved into the opening 19 of the bearing 14b in a defined position of the functional component 30. Thus, the mounting position of the functional component 30 is reached. Subsequently, only the attachment of the closure member 23 in the wall 12 or 13 is necessary.

FIG. 8 thus represents a reliable tongue and groove connection between the functional component 30 and the carrier 10. In contrast to FIG. 10 , in which the shaft 31 is cylindrical and is rotatably positioned on the bearing 14 b, can according to FIG. 5 the shaft 31 have a rib member 38 extending through the opening 22 according to FIG FIG. 2 extends. Here, according to FIG. 2 the closure part 23 a circular segment-like opening 24, so that upon movement of the functional component 30 about the axis of rotation 5, the rib member 38 can move in this opening 24. The rib element 38 is in this case aligned parallel to the axis of rotation 5 of the functional component 30.

As in FIG. 3 can be seen, the functional component 30 is spring-loaded. Here, a torsion spring 6 is used, which has a central region 6a, which is connected to a web 16 of the carrier 10 (s. Fig. 4 ) attacks. In addition, the torsion spring 6 has two free ends 6 b, which are supported directly on the functional component 30. The torsion spring 6 causes after an actuation of the grip element 4 (s. Fig. 10 ) From a rest position in an operating position, the grip element 4 automatically moves due to the spring load in its rest position. The type of arrangement of the torsion spring 6 on the functional component 30 favors a simple assembly of the functional component 30 on the carrier 10, so that only the central region 6a can be fastened in a simple manner to a fastening region 16a of the web 16. The attachment region 16a in this case has an opening according to FIG. 4 into which the central region 6a of the spring 6 is to be threaded.

As FIG. 5 to FIG. 7 show the support member 33 is carried out with a bolt 46, the torsion spring 6 from FIG. 3 receives. Further shows FIG. 7 a support surface 47 in which a crash barrier can act in a potential accident to effectively prevent that the functional component 30 rotates about the axis 5 due to the acting accelerations and thus unintentionally moves the grip element 4 out of the door 2, which would be connected to an unwanted opening operation of the door 2.

As FIG. 2 illustrates, the closure member 23 has a guide rib 25 which can be inserted into a corresponding widening 15 a of the channel 15. By means of this particular embodiment of the closure part 23, a reliable and reinforcing retention of the closure part 23 within the channel 15 is achieved, at the same time the widening 15a serves as an assembly aid and guide aid for inserting the closure part 23 into the channel 15 in the correct position.
