Abstract:
A vehicle seat articulation mechanism comprising a first member intended to be connected to the seat part, a second member intended to be connected to the backrest, about an axis of articulation, reduction gearing arranged between an input member and the second member, a piezoelectric motor having a rotor connected to the reduction gearing to drive the rotation of the second member with respect to the first member through the reduction gearing, in which the reduction ratio of the reduction gearing is greater than or equal to 150, and in which the nominal rotational speed of the piezoelectric motor is less than 500 revolutions/min. Seat comprising such a mechanism.
