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.
