Abstract: A hinge has two arms that can be pivoted relative to one another between a closed initial position and a second position. A first arm has a first guide slide. A second guide slide can be shifted along the pivot axis and can contact the first guide slide. When the two arms are moved towards the initial position, at least one cylinder-piston unit can be loaded by means of the second guide slide. The second guide slide can be rotationally fixedly coupled to the second arm in a first pivoting angle sub-range bordering the initial position and to the first arm in a second pivoting angle sub-range bordering the second position. The hinge has a first control slide rigidly connected to the second arm and a second control slide that makes contact with the first control slide and that is coupled against rotation to the first guide slide.

Abstract: A retraction device includes a housing and a driving element guided in the housing between a parked position and an end position. A first end of a spring energy accumulator is connected to the housing. The spring energy accumulator is loaded to a maximum operating value when the driving element is in the parked position and is unloaded to a residual energy value when the driving element is in the end position. A second end of the spring energy accumulator can either be fixed to the housing or coupled to the driving element by means of a bistable coupling. The coupling has a blocking element that can be moved between the housing and the driving element.

Abstract: A retraction device for two end positions has two driving elements which are connected to one another by a spring energy accumulator. Each driving element is displaceably mounted in a respective guide housing. A sliding door has such a retraction device, and a sliding door arrangement has such a sliding door.

Both guide housings are adjustable relative to one another in the longitudinal direction of the retraction device by means of at least one sliding joint. This provides a retraction device for two end positions, which can be used for a range of door widths without design modifications.
