Plate for a rocker joint chain

1. A plate for a rocker joint chain, said plate comprising: two spaced, substantially parallel longitudinal legs that include an outer longitudinal leg and an inner longitudinal leg and wherein the inner longitudinal leg is closer to a chain bending axis than is the outer longitudinal leg, and two vertical legs that together with the longitudinal legs enclose a plate opening, wherein an indentation is positioned on an outer edge of at least one of the longitudinal legs, and a plate orientation tab is positioned on an outside contour of the plate in a region of a transition from the outer longitudinal leg to a vertical leg for orienting the plate relative to other plates that together form a chain; wherein the orientation tab lies within a pair of imaginary parallel lines that extend along outer edges of the longitudinal legs of the plate; and a stop tab positioned at a region of transition from the inner longitudinal leg to a vertical leg for limiting a bending angle of a chain containing the plate.

2. A plate in accordance with claim 1 , wherein the orientation tab is visible in a top view of a plate.

3. A plate in accordance with claim 2 , wherein the indentation and the orientation tab are visible in at least one visual direction in a plane parallel to a plate plane.

4. A plate in accordance with claim 1 , wherein the orientation tab and the stop tab are positioned on the same vertical leg of the plate.

5. A plate-link chain comprising a plurality of plates in accordance with claim 1 .
