Abstract
The invention relates to a link chain having two rows of chain elements wherein the chain elements of one row are rotatably connected to those of the adjacent row in the chain plane in such a way that each chain element has two rotational axes, of which each one of the two rotational axes of two different chain elements is in adjacent rows, and that the chain elements of one row are connected to one another by means of toothings of their ends in such a way that the chain is flexible in the chain plane, wherein the rotational axes are designed such that the chain remains in a set position.
