For example, the synchronization element extends to more than 80%, in particular more than 90% in the cavity of the center rail. For example, the synchronization element is movable, for example rotatably mounted on the middle rail center wall section or on the middle rail horizontal wall section.

It also proves to be advantageous that the synchronization means have two synchronization elements, which are arranged opposite one another and at a distance from the middle rail. As a result, a synchronization of elements of the guide system is improved, in particular redundant. Advantageously, a synchronization element is designed to synchronize a movement of the carcass rail and a movement of the sliding element rail. It is also conceivable that comparatively more elements of the guidance system can be synchronized with one another than with known guidance system synchronizers. For example, the guide rails can thereby be synchronized with one another and / or in particular simultaneously also the carriages of the guide system.
