12 . The eyeglasses according to claim 10 , wherein at least one eyeglass element selected from the temple and the frame comprises a resiliently biased counter latching element arranged to cooperate with a first latching element of the central part associated with the eyeglass element to define the rest position and to cooperate with a second latching element of the central part associated with the eyeglass element to define the wearing position.
13 . The eyeglasses according to claim 12 , wherein the counter latching element is configured as a spring-loaded piston guided in a locating hole, wherein the first latching element and the second latching element are each formed as latching recesses into which the spring-loaded piston is urged under pretension in the respectively associated functional position selected from the rest position and the wearing position.
14 . The eyeglasses according to claim 10 , wherein the cable is guided in the cable guide opening of the central part from the temple to the frame.
15 . The eyeglasses according to claim 10 , wherein the cable is configured as a ribbon cable or as a flexible printed circuit [FPC] connector.

Description

CROSS REFERENCE TO RELATED APPLICATIONS The present application is a national stage application of International Application No. PCT/EP2021/072765, filed Aug. 16, 2021, which claims priority to German Patent Application No. 102020210683.5, filed Aug. 21, 2020, the entire contents of which are incorporated herein by reference in their entirety. The invention relates to a central part for an eyeglass hinge and to eyeglasses with such a central part. Eyeglasses with electronic functions, such as data eyeglasses, augmented reality eyeglasses, also known as AR eyeglasses, or virtual reality eyeglasses, also known as VR eyeglasses, are becoming increasingly important. In such eyeglasses, an electronic functional element, for example a display device or the like, is typically integrated into a frame of the eyeglasses or arranged on the frame, wherein a control device, for example a controller and/or an electrical storage device, for example a battery or accumulator, is integrated into a temple of the eyeglasses or arranged on the temple. An energy- and/or data-transmitting connection is then required between the temple on the one hand and the frame on the other. For this purpose, a cable may be provided, be it an electrical cable or an optical cable, which must be passed over a hinge connecting the temple to the frame. Conventional eyeglasses and eyeglass hinges can hardly be used for this purpose and can also be retrofitted accordingly only with difficulty or at considerable expense. In particular, there is a need for a cable guide via the hinge, which is simple in design and protects the cable from outside the eyeglasses, while at the same time ensuring that the eyeglasses can be easily mounted and dismounted, especially for maintenance purposes. At the same time, functions typical of hinges, such as the most accurate possible definition of various functional positions for the temple, in particular a rest position and a wearing position, are to be ensured. It is also generally desirable to realize a so-called snap effect, whereby the temple is automatically displaced into at least one of the said functional positions as soon as it reaches or exceeds a certain limit angle range relative to the frame. The invention is based on the problem of creating a central part for an eyeglass hinge as well as eyeglasses having such a central part, wherein advantages are provided at least to some extent over conventional eyeglass hinges, wherein in particular at least one of the aforementioned aspects is realized. The problem is solved by providing the present technical teaching, in particular the teaching of the independent claims as well as the embodiments disclosed in the dependent claims and the description. In particular, the problem is solved by providing a central part for an eyeglass hinge comprising a first articulation region adapted to articulate the central part about a first articulation axis to a frame of an eyeglasses. The central part has a second articulation region adapted to articulate the central part about a second articulation axis to a temple of the eyeglasses. The central part also has a cable guide opening penetrating it perpendicularly to the articulation axes, which is adapted to guide a cable from the temple to the frame through the central part, in particular an electronic cable or an optical cable, in particular a cable for power and/or data transmission. The cable guide opening is open at least on one side in the direction of the articulation axes. With the central part proposed here, in particular a simple and at the same time gentle as well as safe guidance of a cable from the temple to the frame can be provided. In particular, eyeglasses having the central part can be easily mounted by hinging the central part to the frame in the first articulation region and hinging it to the temple in the second articulation region. Thus, an eyeglass hinge for the eyeglasses is formed at the same time, with the frame, the temple and the central part together forming the eyeglass hinge. The cable is already protected by the fact that a pivoting movement of the temple relative to the frame from a rest position to a wearing position and back is divided into two partial pivoting movements, namely a first partial pivoting movement of the central part relative to the frame about the first articulation axis, and a second partial pivoting movement of the temple relative to the central part about the second articulation axis. In order to realize the full pivoting angle of the temple relative to the frame of typically about 90°, only a significantly reduced pivoting angle is required with respect to each of the two partial pivoting movements, in particular—with symmetrical division of the pivoting movement into the two partial pivoting movements—a respective partial pivoting movement of about 45°. Thus, in the area of a transition from the temple to the central part on the one hand and from the central part to the fra
