ABSTRACT:
A door system, particularly for a passenger plane, includes bearing and guiding device which operates between the door leaf and the door frame, as well as a lifting device which is arranged between the bearing and guiding device and the door leaf. The lifting device moves the door leaf at the end of the closing movement transversely to the moving path (B) of the guiding device with a form-locking engagement with door-frame-fixed receiving elements into the completely closed position and, at the start of the opening operation, in the opposite lifting direction (A) out of the form-locking engagement. The lifting device contains lifting kinematics for the control of the door blade lifting movement and an assigned lifting drive. In order to ensure a high safety standard and, at the same time, a simple weight-saving construction, the door leaf is provided with an electric drive unit for the lifting drive and a mechanically actuated lift securing device which can be cleared in parallel to the electric control of the lifting drive by a door opening command and locks the lifting device in the completely closed position automatically in a door-leaf-fixed manner.
