Patent ID: 8348343

Claim:
A method for controlling kinematics of a seat ( 10 ) having at least two movable portions ( 16 , 18 , 20 , 22 ) movable relative to each other, and at least two actuators ( 24 , 25 , 26 , 27 ) configured to move the movable portions in order to modify a configuration of the seat from an initial position to a final position determined by a user, the method comprising: establishing ( 102 ), an authorized travel conduit (C), between the initial position and the final position, for a predetermined specific point of the at least one of the movable portions, the travel conduit (C) being delimited by at least two opposite lateral boundaries (Z 1 , Z 2 ); calculating ( 116 ) a current position of the specific point and a current movement direction of the specific point; establishing ( 118 ) a target direction for the specific point that is sufficient for moving the specific point in the authorized travel conduit (C) from the at least two boundaries (Z 1 , Z 2 ) of the associated travel conduit and the current position of the specific point; and modifying ( 122 ) a direction of the specific point by controlling at least one of the at least two actuators in order to force the specific point to move within the travel conduit (C) and in the target direction as far as the final position of the seat.
