Abstract
An anti-backbend chain comprises a plurality of alternate chain links joined by respective chain hinges, a spring element comprising at least a first spring arm being provided. The spring element rests on a chain hinge and the first spring arm extends to a neighbouring chain hinge and is movably in contact therewith under the biasing force of the spring element, so as to obstruct bending of the anti-backbend chain in a first pivot direction. In addition, an anti-backbend chain drive is provided, in particular a chain drive for driving automated door or gate systems.
