Abstract: An electromechanical transmission apparatus for actuation systems for guidance systems of an aircraft, includes a planetary gear system configured to provide a kinematic transmission between a driving element and an output shaft. The planetary gear system includes a central sun gear planet gears coupled rotatably to a planet carrier, and an external ring gear; furthermore having an electromechanical brake and a viscoelastic damper, the electromechanical brake being configured to lock and release selectively the viscoelastic damper and the central sun gear so that the electromechanical transmission apparatus can be configured: in an active configuration, and An electronic control unit is configured to control the electromechanical brake so as to make the transmission apparatus pass from the active configuration to the passive configuration when a locking condition of the driving element occurs.

Abstract: A seating system is provided which comprises a seat movable between a standard seating position, in which the seat faces frontwards and the seat backrest is in an upright position for conventional driving mode, and at least one non-standard seating position in which the seat is rotated around a vertical axis with respect to the standard seating position and the backrest is reclined rearwards by rotation around a first transverse horizontal axis from the standard seating position. The seat is equipped with at least one passive safety device switchable between a working or active state, in which the device is able to protect an occupant of the seat in case of an impact of the vehicle, and a non-working or inactive state.
