摘要

The door has a locking device for automatic locking of an airfoil. A torsion bar (23) is accommodated fixedly with vertically running bar sections (16, 17) in a fastener, while a horizontal bar section cooperates with a driver or a stop (18) during swiveling of the door, where the driver is provided at an airfoil side and the stop is provided at a side of a frame or a door frame. The vertically running bar sections run at a rotatable section of the driver or the stop. The vertically running bar sections are movable relative to the driver or the stop during swiveling of the airfoil.
