Description

The invention relates to a handle of a motor vehicle with a carrier which is fastened on the inside to a movable part of the motor vehicle, a compensating weight movably mounted on the carrier, on which a handle element which can be actuated from the outside of the movable part engages, one movably mounted on the carrier Recording on which a force transmission element can be fastened, which can be brought into operative connection with a lock of the movable part and a shaft which connects the receptacle with the balance weight.

In the EP 10 191 475 is a handle of a motor vehicle disclosed with a movably mounted balance weight ( 13.1 ) is executed, which about a rotation axis ( 13.4 ) movable on a support ( 12 ) is stored. The balance weight ( 13.1 ) is replaced by a return spring ( 11.1 ) spring loaded. Distances to balance weight ( 13.1 ) is a recording ( 13.2 ) provided for a Bowden cable. A wave around the axis of rotation ( 13.4 ) is movable, connects the balance weight ( 13.1 ) with the recording ( 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.

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.

For this purpose, the invention provides 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 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 take-up, counterweight 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 grip element, which is movably mounted on the movable part, in particular on the motor vehicle door, in one possible embodiment has 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.

To ensure satisfactory stability of the carrier, preferably made of a plastic is designed to ensure, the carrier has a plurality of walls, wherein a wall separates the balance weight of the recording. In one possible embodiment of the invention, a wall may have a fastening device which captively holds the functional component on the carrier. In addition, the fastening device can be designed in several parts and have at least one latching connection, which is 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 elongated 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 middle area of the spring be fixed to the fixed bridge of the support. 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.
