The joint device G for coupling the console part 15 with the base part 10 is designed as a ball joint device. This is on the console part 15 a first guide part 15a arranged by the console part 15 protrudes and preferably formed pin-shaped. In one embodiment of the adjusting device is on the pin-shaped guide member 15a an at least partially spherical condyle 30 attached so that the guide part 15a the condyle 30 on the console part 15 stored or attached.

Optionally, as it is in the 1a . 2 and 3 is shown at a location opposite or diametrically opposite to the position of the first guide member on the condyle 30 located, a second pin-shaped guide part 15b at the condyle 30 be attached, which is formed pin-shaped. In the provision of two guide parts 15a . 15b these are preferably on the vertical or Z -Axis. These embodiments may provide a kinematics suitable for particular applications.

On the spherical area of the condyle 30 is a joint cup 20 spatially rotatable, on which the base part 10 is fixed. The joint cup 20 preferably has a partially spherical inner surface, which has the largest diameter of the joint head 30 includes, so that the joint shell 20 coupled with the condyle. For this purpose, the joint device can be produced in a mold in a plastic injection molding process.

Through the coupling of condyle 30 and joint cup 20 the joint cup is spatially rotatably mounted with the base part. Furthermore, the joint shell 20 at least one circumferentially rectilinear elongated recess portion 25 for receiving a portion of the at least one guide part 15a . 15b on. The guide part 15a is or the guide parts 15a . 15b are arranged such that this or this with one of the joint shell 20 facing portion of the recess portion 25 is taken up or be, so that the joint shell 20 in a predetermined angular range on the condyle 30 is spatially rotatable, wherein the guide part 15a or the guide parts 15a . 15b in the recess section 25 to be moved.

In the provision of two guide parts 15a . 15b can also have two recess sections 25a . 25b be arranged, the sections in the circumferential direction of the joint shell 20 run while aligned in the same circumferential direction, wherein the first guide part 15a in a first recess section 25a and the second guide part 15b in a second recess portion 25b protrudes into it. In this embodiment, therefore, in each recess section 25a . 25b each a guide part 15a . 15b with a recess sections 25a . 25b led to the facing section. In the 3 is this embodiment with two guide parts 15a . 15b and with two recess sections 25a . 25b dargstellt, wherein the lower recess portion 25a in a console part 15 facing area of the joint shell 20 is arranged and the upper recess portion 25b to the lower recess portion 25a is diametrically opposed.

In general, at least one further guide part and at least one further recess for at least partially receiving the same may be provided. The number of guide parts and the number and shapes of the recesses may in particular depend on the kinematics to be provided and the desired stability of the arrangement according to the invention.

The one recess section 25 or the alternatively provided two recess sections 25a . 25b can as opening or openings or as a recess or depressions of the inner surface of the joint shell 20 be educated.

For spatial fixation and / or release of the rotational position of the joint shell 20 with the base part and thus with the armrest part 11 is an adjustment device arranged on the base part 40 with one towards the condyle 30 provided reciprocating adjustment part. In one embodiment of the invention, the adjustment part has a locking and releasing element or a locking part 43 , which by means of an actuator 50 opposite the condyle 30 can be moved back and forth or retracted and extended. The locking element can in its direction of movement on the base part 10 or on the joint cup 20 be guided by a guide device. With the adjustment device 40 that's from the joint cup 20 on the condyle 30 acting lock and release element 43 movable. This allows a spatial fixation of the joint shell 20 for determining the rotational position of the joint shell 20 and thus the base part 10 opposite the condyle 30 as well as the release of the joint shell 20 opposite the condyle 30 respectively. To move the adjusting device 40 is a cooperating with this actuator 50 with an actuating element 51 intended. With the lock and unlock element 43 and / or with the actuator 50 can be a locking and releasing device 55 coupled, with a locked state can be made and maintained and can be solved accordingly.

The adjustment device 40 in particular, the lock and release element 43 have, by means of the actuator 50 in each case a recess of a plurality of locking receptacles or recesses 23 of the condyle 30 is retractable to fix the rotational position of the joint shell on the joint head, and can be moved out of the respective recess to rotate the joint shell relative to the joint head. The recesses 23 are according to the intended rotational positions, in which a latching of the base part 10 is provided over the surface of the condyle 30 distributed (in the representation of 3 is for better illustration only one recess 23 the plurality of recesses shown). The arrangement, ie the location and number of locking receptacles depends on the spatial positions of the base part to be provided 10 in the respective application. The recesses may be in particular holes with a circular diameter.

According to an alternative embodiment, it is provided that the adjusting device 40 one by means of the actuator 50 reciprocating adjustment part in the form of a rest or friction body (not shown), which by actuation of the actuator 50 for fixing the rotational position of the joint shell 20 and the base part 10 with a predetermined force on the surface of the condyle 30 can be pressed. In this case, the surface of the condyle 30 even, ie without locking receptacles or recesses 23 be trained. Furthermore, to produce the mobility of the base part relative to the condyle, the actuating device and / or the locking and releasing device 55 be designed such that by actuation of the actuator 50 a lower pressure force can be set to produce the mobility of the joint shell, in which an inhibited movement of the joint head can take place on the condyle. Alternatively or additionally, the actuating device and / or the locking and releasing device 55 be designed such that the inhibiting or friction body at a distance from the surface of the condyle 30 can be brought to the joint shell free on the condyle 30 to be able to turn.
