Abstract
A sealing device of a sliding door having a slidably mounted door leaf has a drop-down seal having a sealing strip and a lowering mechanism for automatically lowering and raising the sealing strip. The lowering occurs against a restoring force. The sealing device also has an activation unit for activating the drop-down seal. The activation unit has a contact surface, which is directed upward in the lowering direction, and a contact element, which lies against said contact surface during the closing of the door leaf and thereby actuates the drop-down seal. In this way, the weight of the door leaf can be used for the lowering of the sealing strip. Furthermore, a position in which the restoring force does not influence a sliding motion of the door leaf in the longitudinal direction of the sealing strip can be achieved.
