It is the object of the present invention to provide a joint for a movable component of a motor vehicle, in which a joint head of the joint can be fixed in a particularly simple and reliable manner so that it can only perform its intended rotational degrees of freedom. This object is achieved by a joint for a movable component of a motor vehicle having the features of claim 1. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the dependent claims.

The joint according to the invention for a movable component of a motor vehicle comprises a joint head on which an extension for connecting the joint head to the component is arranged. Furthermore, the hinge comprises a holder having a socket for supporting the condyle and having a mounting opening which has a larger diameter than the condyle for axially inserting the condyle into the holder. The socket has on the circumferential side adjacent to the mounting opening recess through which the extension in the radial direction in the socket is inserted, wherein the recess is narrower than a diameter of the condyle. In addition, the socket on the front side an opening for the extension with a smaller diameter than the condyle.

During assembly of the joint, the condyle can first be introduced in the axial direction through the mounting opening of the holder, since the mounting opening has a larger diameter than the condyle. The condyle is inserted as far as through the mounting hole until the condyle arranged in the axial direction behind the socket and the extension of the condyle above or adjacent to the recess is disposed adjacent to the mounting hole. Subsequently, the condyle is moved together with its extension in the direction of the socket, as a result, the arranged on the condyle extension passes through the recess of the socket into the socket. Thereafter, the condyle can be withdrawn into the socket. Characterized in that the frontal opening of the socket has a smaller diameter than the condyle, the condyle can not be transported out through this opening. The fact that the peripheral recess of the socket is narrower than the diameter of the condyle, the condyle can not pass through this recess from the socket.

In the joint according to the invention it is therefore particularly easy to mount the condyle on the holder and in particular to fix the condyle in the socket so that the condyle can only perform its intended rotational degrees of freedom. In the joint according to the invention, it is not necessary to provide fixing elements or additional retaining elements in order to reliably fix the condyle in the joint socket. The assembly of the joint according to the invention is thus particularly simple and can be carried out in particular tool-free.

As a result, the rotary joint has particularly large rotational or pivoting degrees of freedom.

In a further advantageous embodiment of the invention, it is provided that the joint socket is substantially hemispherical. As a result, the socket can enclose the condyle particularly well and safely, in addition, a particularly simple installation of the condyle is ensured in the joint socket.

In a further advantageous embodiment of the invention, it is provided that forms the intended purpose of the condyle in the joint socket of the condyle with the socket a snap connection. This can for example be realized by the joint socket is elastic. If the condyle is positioned in the intended arrangement within the socket, the said snap connection is received. It is also possible that the socket is slightly larger than a hemisphere shell. When the condyle is retracted into the socket, the socket can thus enclose the condyle more than 180 ° with respect to a circumferential direction. In other words, the joint socket thus snaps around the condyle when it is moved into the socket. In addition, it is also possible that in the joint socket, for example, elevations and / or depressions are provided, in which the condyle snaps into its intended arrangement. In this way it is also possible to fix the condyle reliably and permanently in the socket. The said snap connection is preferably detachable again. If necessary, therefore, the condyle can be easily loosened and disassembled again from the socket.

A further advantageous embodiment of the invention provides that the extension is rod-shaped at least in an area adjacent to the condyle. Preferably, the rod-shaped extension has a round cross-section. The frontal opening in the socket is preferably also round in the case. By appropriate dimensioning of the opening on the front side of the socket and the dimensioning of the diameter of the extension can be determined, how large the pivoting or rotational degree of freedom of the rotary joint.

According to a further advantageous embodiment of the invention, it is provided that the rotary joint is designed for pivotable and / or rotatable bearings of an interior or exterior component of a motor vehicle. For example, the rotary joint can be used to support a display inside a motor vehicle rotatably or pivotally. Furthermore, the rotary joint can also be used, for example, to mount ventilation nozzles pivotable or rotatable. In addition, it is also possible that the rotary joint is used, for example, to rotatably and / or pivotably mount an exterior mirror of a motor vehicle.

In principle, the rotary joint can be used for any components which are to be mounted pivotably and / or rotatably in or on the vehicle.

Finally, a further advantageous embodiment of the invention provides that the holder is an injection molded part. As a result, the holder can be produced inexpensively in particularly large quantities. The condyle may also be a plastic part. Alternatively, it is also possible that the condyle is made, for example, of a metallic material. Furthermore, it is also possible that the holder is for example a casting. Also in this case, it is possible to produce the holder in large numbers particularly cost.

In the figures, identical or functionally identical elements have been provided with the same reference numerals.

A partially illustrated joint 10 for movably supporting a component of a motor vehicle is in a perspective view in 1 shown. The joint 10 includes a holder 12 with a socket 14 for storing a condyle, not shown here 16 (please refer 2 ). Furthermore, the holder includes 12 a substantially round mounting hole 18 which has a larger diameter than the condyle 16 for axial insertion of the condyle 16 in the holder 12 having.

The joint socket 14 has circumferentially one to the mounting hole 18 adjacent recess 20 on, through which a in 2 shown extension 22 , which is arranged on the condyle 16, in the radial direction in the joint socket 14 is insertable. In addition, the joint socket 14 the front side still a substantially circular opening 24 for the extension 22 on. The diameter of the opening 24 is smaller than the diameter of the condyle 16 ,

In 2 is the joint 10 shown in a further perspective view, wherein the condyle 16 straight in the axial direction through the mounting opening 18 of the owner 12 is introduced. Because the diameter of the mounting hole 18 greater than the diameter of the condyle 16, the condyle can 16 easily through the mounting hole 18 be moved through. As you can see, the condyle is 16 designed as a ball head, wherein the socket 14 is designed as a ball socket. The joint socket 14 is essentially hemispherical in shape.

In 3 is the joint 10 during assembly of the joint 10 shown in a further perspective view. The condyle 16 is instantaneously through the mounting hole as shown 18 moved through. While passing the condyle 16 through the mounting hole 18 the condyle 16 is at the height of the mounting hole 18 held so that the condyle 16 easily through the mounting hole 18 can be passed.

In 4 is the assembly process of the joint 10 shown in a further perspective view. The condyle 16 has now been completely through the mounting hole 18 passed, leaving the condyle 16 as shown behind the socket 14 located. After that, the condyle became 16 together with the extension 22 in the radial direction in the direction of the socket 14 emotional. This is the extension 22 simply in the radial direction through the peripheral recess 20 the joint socket 14 which moves to the mounting hole 18 borders. The extension 22 is doing together with the condyle 16 lowered until the condyle 16 at least substantially at exactly the right height for the socket 14 located.

In 5 is the joint 10 shown in the assembled state in a perspective view. Starting from the in 4 shown position of the condyle 16 this was in the direction of the socket 14 moved, and that until the condyle 16 with its outer surface on an inner surface of the socket 14 is applied. For mounting the condyle 16 So this is first in a first axial direction through the mounting holes 18 moved through. After that, the condyle becomes 16 transversely to the first axial direction - ie in the radial direction - lowered, so that the extension 22 through the circumferential recess 20 of the socket 14 through submerged; so far, until the extension 22 and a central axis of the socket 14 aligned. Subsequently, the condyle becomes 16 moved in a second axial direction opposite to the first axial direction until the condyle 16 on the socket 14 has been arranged adjacent.

In the present presentation, it can be seen again that the unspecified frontal opening 24 the joint socket 14 a much smaller diameter than the condyle 16 so that the condyle 16 not from the socket 14 can be pulled out. Furthermore, you can also see well that the unspecified here peripheral recess 20 the joint socket 14 much narrower than the diameter of the condyle 16 is. Thus, the condyle 16 after its intended assembly not in the radial direction or upwards from the socket 14 to be moved.

It can be provided that in a proper installation position of the joint 10 the socket 14 - As shown in the figures - below the mounting hole 18 is arranged. So remains alone due to gravity of the condyle 16 inside the socket 14 , In addition, it may also be provided that in the assembled state, ie when the joint head is arranged as intended 16 in the socket 14 , the condyle 16 with the socket 14 forms a snap connection. This can be achieved for example by the fact that the joint socket 14 is formed elastically, so that said snap connection is formed. This can additionally ensure that the condyle 16 safely in the socket 14 is held.

The described joint 10 can be mounted very easily, in particular no tools for additional fixation of the condyle 16 in the socket 14 necessary. The joint 10 can be used essentially for the pivotable and / or rotatable bearings of any interior or exterior components of motor vehicles.

So can the joint 10 For example, serve to pivotally and / or rotatably support an interior mirror or an exterior mirror of a motor vehicle. For example, it is also possible for the joint 10 to use for storing a display pivotable and / or rotatable in the vehicle interior. So can the joint 10 For example, be used to pivot a lid of a glove box, lid of other storage compartments or the like and / or rotatably to store.
