Abstract: The present invention relates to equipment (80, 80A, 80B, 80C, 80D, 80E) for an airplane seat (36A) having at least two states comprising a first antenna (150A) able to transmit a state signal (158A) relative to the state of the equipment (80, 80A, 80B, 80C, 80D, 80E) and a second antenna (154A) able to receive a control signal (182) to change the state of the equipment (80A).

Abstract: A method for controlling the kinematics of a seat having movable portions and actuators for moving the movable portions between an initial position and a final position, at least one movable portion including a specific point, including the steps of establishing, for the specific point, an authorized travel conduit between the initial position and the final position, delimited by two lateral boundaries, calculating the current position of the specific point, establishing a target direction for the specific point that is suitable for moving the specific point in the conduit from the lateral boundaries and the current position, and modifying the direction of the specific point by controlling the actuators in order to force the specific point to move in the conduit.

Abstract: A method for controlling the kinematics of a seat (10) having movable portions (16, 18, 20, 22) and actuators (24, 25, 26, 27) for moving the movable portions between an initial position and a final position, at least one movable portion including a specific point (P1, P2, P3, P4), includes the steps of: establishing (102), for the specific point, an authorized travel conduit (C) between the initial position and the final position, delimited by two lateral boundaries (Z1, Z2); calculating (116) the current position of the specific point; establishing (118) a target direction for the specific point that is suitable for moving the specific point in the conduit (C) from the lateral boundaries and the current position; and modifying (122) the direction of the specific point by controlling the actuators in order to force the specific point to move in the conduit (C).

Abstract: A method for controlling a seat which is equipped with: at least one controllable actuator (20) for moving two portions (16, 18) of the seat relative to each other; a controllable lock (26) for positive mechanical locking of the movement of the two portions of the seat, the lock (26) being able to be displaced between an engaged position opposite a complementary stop (30) and a disengaged position remote from the stop (30), which method comprises, in the event of an order for modification of a command for the actuator (20), steps for: verifying whether the two portions (16, 18) are in a critical range (I) of relative positioning, and as long as the two portions (16, 18) are in the critical range (I), applying to the actuator (20) a command which is different from the modified command.

Abstract: The seat has moving parts, at least one actuator, and a control unit. The control unit comprises: tracking means for tracking the current position of each actuator; and management means for managing the control of each actuator. The management means comprise: computation means for computing the current position of a critical point of the seat; evaluation means for evaluating the current position of each critical point of the seat relative to a boundary; and control means for controlling at least one actuator independently of the control selected by the user.
