A seat, in particular an aircraft seat, having a seat support structure having at least one seat surface with a seat surface frame and a backrest with a backrest frame being pivotable relative to the seat surface, a base support element supporting the seat support structure, and a seat adjustment arrangement, which includes at least one coupling unit movable relative to the base support element, the coupling unit is configured to connect the seat surface frame and the backrest frame to one another and which is provided with at least one bearing element, and which includes at least one guide element in which the bearing element is movably guided. The seat adjustment arrangement being adapted to transfer the seat support structure into a sitting position, a comfort position or lying position by displacing the bearing element along the guide element.

A method of automatic positioning a seat in an apparatus comprising two cameras located on either side of the seat, each one in a position able to acquire images of a face of a user seated on the seat. The seat comprises at least one motor, each motor acting on a position of the seat along a predefined axis. The method comprises: for each camera: obtaining a position of a predefined image zone in which at least one eye of a user of the apparatus should be located; acquiring an image of a user seated on the seat; detecting at least one eye of the seated user in the image acquired; and obtaining a relative position between each eye detected and the predefined zone. By using each relative position obtained, at least one motor is actuated until each predefined zone contains at least one eye of the seated user.

An aerial workstation which comprises a seat having a sitting portion, a backrest that is connected by a first articulation that allows the backrest to pivot relative to the sitting portion, and an arm configured to position the seat in various positions and orientations in space as required. The aerial workstation makes it possible to be able to translate the seat in a cockpit in an introduction direction, and to make it pivot about a pivot axis that coincides with the direction of introduction within the cockpit.

A lift assist system for an aircraft seat is disclosed. The lift assist system may include one or more pivoting lift rails configured to couple to one or more fixed seat pan rails of a seat pan frame. The lift assist system may include an actuator sub-system. The actuator sub-system may include an actuator configured to actuate the seat pan frame between one or more positions by actuating the one or more pivoting lift rails a predetermined distance.

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.

An override bypass assembly comprises a cable and a pulley wheel operably connected to the cable. The cable in operation rotates the pulley wheel when tension is applied to the cable. The override bypass assembly also comprises a telescoping cylinder assembly operably connected to the pulley wheel. The pulley wheel in operation moves the telescoping cylinder assembly to an unlocked position. The override bypass assembly further comprises a biasing mechanism operably connected to at least one of the pulley wheel and the telescoping cylinder assembly. The biasing mechanism in operation moves the telescoping cylinder to a locked position when tension applied to the cable is relieved.

A rotational brake assembly comprises: a swivel disc having an outer diameter and a plurality of locking holes proximate the outer diameter; a cam having an angled slot; a lifting pin located within the angled slot of the cam; and a rotational brake pin operably connected to the lifting pin. The cam in operation moves to at least one of a locked position and an unlocked position based on an input. The lifting pin in operation moves along the angled slot when the cam moves. The rotational brake pin in operation moves due to motion of the cam. The rotational brake pin in operation moves from an engaged position with the swivel disc to a disengaged position, when the cam moves from the locked to the unlocked position. The rotational brake pin in operation moves to the engaged position, when the cam moves to the locked position.

A seat locking mechanism comprises: a plurality of positional brake mechanisms including a longitudinal brake assembly, a lateral brake assembly, and a rotational brake assembly; and a carriage assembly operably connected to the plurality of positional brake mechanisms. The carriage assembly having a carriage tube and a carriage housing fixedly connected to the carriage tube. The carriage assembly in operation moves each of the plurality of positional brake mechanisms to at least one of a locked position and an unlocked position, when the carriage assembly rotates.

A seat locking mechanism comprises a plurality of positional brake mechanisms including a longitudinal brake assembly, a lateral brake assembly, and a rotational brake assembly; and an electric motor assembly operably connected to each of the plurality of positional brake mechanisms. The electric motor assembly comprises: a drive motor; a clutch system located between the drive motor and the plurality of positional brake mechanisms; and a solenoid operably connected to the clutch system. The solenoid in operation engages the clutch system to operably connect the electric motor to the plurality of positional brake mechanisms when the electric motor assembly is activated and disengages the clutch system to operably disconnect the electric motor to the plurality of positional brake mechanisms when the electric motor assembly is deactivated. The electric motor assembly in operation moves the plurality of positional brake mechanisms to at least one of a locked position and unlocked position.
