Safety device for automated door systems, door system equipped therewith and operating method for such a door system

A safety device for an automated door system, the safety device comprising:

• a sensor device, designed to be arranged on the door system such that an associated detection region of the sensor device covers a danger region of an associated door leaf using sensors, and configured to detect the presence of an object within the associated detection region, and
• a control device, wherein the control device is configured
• to change the associated detection region on the basis of a current movement speed of the associated door leaf and/or
• to determine a detection geometry and to actuate a door drive of the associated door leaf such that a predetermined movement speed of the associated door leaf is provided depending on the determined detection geometry and/or a braking force and/or a braking distance of the associated door leaf is or are adapted to the current movement speed of the associated door leaf.
