Attachment device for movably attaching monitor to aircraft passenger seat, has friction unit loading knuckle unit with force to fix support arm in usage condition and comprising adjustment element for changing force based on pivoting angle

摘要

The device (10a) has a main knuckle unit (18a) for guiding a support arm (16a) along a pivoting area relative to a seat (14a). A friction unit loads the main knuckle unit with frictional force for fixing the support arm in a usage condition. The friction unit has an adjustment element for changing the frictional force based on a pivoting angle. The friction unit and the adjustment element are designed as a single-piece, and a locking unit locks the support arm and an energy storage unit in a form-fit manner, where the friction unit has a brake lining. An independent claim is also included for a method for movably attaching an object to a seat.
