A seat base includes a plurality of linear actuators each having a first end pivotally mounted to a base member and a second end pivotally mounted to a seat member. A controller is adapted for controlling an extension length of each of the plurality of linear actuators in a coordinated manner for adjusting a position of the seat member with six degrees-of-freedom and for damping vibration of the seat member. An active vibration mitigation method for reducing vibrations of an aircraft seat includes receiving vibration data from one or more accelerometers mounted to the aircraft seat and determining a vibration profile based on the vibration data. When vibration mitigation is warranted, control signals for damping vibration are determined and transmitted to a plurality of linear actuators adapted to support the aircraft seat.

Aircraft seat

A powered seat-base release system includes a rod rotatably mounted in a bucket assembly of an aircraft seat and a motor mechanically coupled to the rod. The motor is configured for rotating the rod from a locked position to a released position. A locking mechanism is configured for preventing motion of the bucket assembly. A cable has a first end and a second end, the first end being mechanically coupled to the rod, and the second end being mechanically coupled to the locking mechanism. A user interface is configured to activate the motor for rotating the rod to the released position such that the rod pulls the cable thereby releasing the locking mechanism to enable motion of the bucket assembly. Upon deactivation of the motor, a biasing mechanism is configured to counter rotate the rod from the released position to the locked position thereby back driving the motor.
