  • Lock mechanism for securing a door kinematics system and process of operating same
    Patent number: 6951320
    Abstract: A device for locking a door kinematics system of the door of an airplane includes a control unit, an actuator for actuating a locking system and an automatic reset device. The control unit actuates the actuator as a function of the existence of a predetermined signal so that the actuator brings the locking system in a locking position. The reset device, if required, brings the locking system autonomously into a release position.

  • Actuation mechanism for swinging an aircraft door
    Patent number: 6742744
    Abstract: An structurally simplified actuation mechanism for swinging an aircraft door from a frame on an aircraft fuselage. The actuation mechanism includes a cantilever rotatably mounted to the frame and including a receiving region, a universal joint supported in the receiving region, and an actuation device disposed on the cantilever. The universal joint defines a vertical axis of rotation and is configured to receive a door fitting. The actuation device includes an output drive connected to the universal joint at the vertical axis of rotation.
