Telescopic rail

A telescopic rail:

• comprising at least one inner rail element, at least one middle rail element, and at least one outer rail element, wherein the inner rail element and outer rail element are each longitudinally displaceably supported at the middle rail element over rolling members that are guided in a rolling member cage,
• wherein the rail elements are mechanically force-coupled via a rail synchronization arrangement such that on a longitudinal displacement of the outer rail element with respect to the inner rail element, the middle rail element is longitudinally displaced with respect to both the inner rail element and the outer rail element;
• and
• at least one rolling member cage is mechanically force-coupled to at least one of the rail elements via a respective rolling member cage synchronization arrangement such that a longitudinal displacement of the middle rail element with respect to the inner rail element or outer rail element results in a longitudinal displacement of the corresponding rolling member cage with respect to the middle rail element,
• wherein the rolling member cage synchronization arrangements are force-coupled to the rail synchronization arrangement via a coupling arrangement, with the rolling member cages being driven by the rail synchronization arrangement, via at least one pulling element and with the pulling element including at least one of the following:
• coupling the rolling member cages to one another, running around a drive element that is driven by a pinion of the rail synchronization arrangement, and arranged at the middle rail element.
