Abstract
A link chain has alternating inner and outer chain links connected by a chain articulation, having a direction of motion, wherein each inner chain link has at least one inner plate, and each outer chain link has at least two outer plates and two chain link pins connecting these plates, each pin being rotationally fixed in a pin opening of the associated outer plate and extending through a link opening of the associated inner chain link to form a chain articulation. The inner and/or outer chain links have plate backs contactable with a tensioning rail or guide rail. A forward region of the plate backs in the direction of motion of a part of the inner and/or outer plates extends at an angle to a plane projected between the center lines of the pin openings or link openings. The vertex of the angle points away from the direction of motion.
