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.

A seat assembly with a first seat row that includes a first seat row, and a second seat row including a second seat and located behind the first seat row so that the second seat is located behind the first seat. The first seat has a seating surface provided by a seat structure, and a backrest. The backrest has a vertical pivot axis and is pivotable about the pivot axis, and includes two vertical lateral edges, the horizontal connection of which defines a transverse direction and between which a central line of the backrest is defined in the center. The pivot axis is formed by a vertical axis and is arranged in a position which is displaced from the central line of the backrest in the transverse direction. Pivoting the backrest about the pivot axis releases the seating surface of the first seat for a user of the second seat.

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 actuation control system is disclosed. The seat actuation control system may permit multiple functions to be controlled by a single actuator. For example, a seat floor tracking function, and a seat pan track and swivel function may be individually controlled by a single actuator, such as a rotary actuator.

A vehicle seat includes a seat, a swivel connected to and rotatably supporting the seat, a swivel frame connected to the swivel, a first lateral rail supporting the swivel frame, the first lateral rail permitting the swivel frame to move in a first direction, and a first longitudinal rail supporting the first lateral rail such that the first lateral rail is movable along the first longitudinal rail, thereby permitting the swivel frame to move in a second direction that is perpendicular to the first direction.

A seat pan includes a break over function. The break over enables downward motion of a portion of the seat pan. The downward motion of the portion of the seat pan allows a distance between passenger seats to be reduced while maintaining a minimum required egress distance between the passenger seats. The breakover seat pan assists in egress. The portion of the seat pan may be actuated upwards to increase the length of the seat pan while a passenger is seated. The seat pan thus creates a supported seat surface when an occupant sits on the seat while presenting with a reduced surface when not occupied.

A seat for an aircraft is provided that includes a seat pan, having a seat pan front edge and a seat pan rear edge, a backrest, having a backrest top edge and a backrest bottom edge, where the backrest bottom edge is articulately disposed adjacent to the seat pan rear edge, a headrest, having a headrest top edge and a headrest bottom edge, where the headrest bottom edge is articulately disposed adjacent to the backrest top edge, a tracking device disposed beneath the seat pan and being attachable to a floor of the aircraft, the tracking device permitting the seat pan to translate in at least one of a lateral direction and a longitudinal direction, and a swivel connected between the tracking device and the seat pan, permitting the seat pan to rotate with respect to the tracking device.

A seat actuation control system includes at least one seat having a plurality of seat devices and a plurality of control modules interconnected over a communication bus. Each module is associated with a corresponding seat control device and is configured to control its corresponding seat device. Each module includes a processor and a memory coupled to the processor and storing program instructions therein which include receiving a status packet from each of the other control modules over the communication bus, processing the status packet for updating the overall system status, and actuating the seat device based on the overall system status. The program instructions further include determining status of the corresponding seat device, generating a status packet including the status information, and broadcasting the status packet to the other modules over the communication bus.

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.

A seat system includes a base support structure having at least one flat seat support surface, a seat pan support structure movably coupled to the base support structure and having at least one contoured seat support surface, and a back rest support structure movably coupled to the base support structure. The back rest support structure includes a primary frame having at least one flat back support surface, and an articulating frame movably coupled to the primary frame and having at least one contoured back support surface. The seat system also includes a back rest cushion having an occupant-facing back rest surface, and an articulating arrangement of back rest cushion support members movably coupled together to define a bottom surface of the back rest cushion opposing the occupant-facing back rest surface.
