  • Publication number: 20160258548
    Abstract: A driving device comprises a support, an actuator provided with an output shaft and fixed to the support, and an arm having a distal point provided to be connected to the closing member. A kinematic chain converts a rotation of the output shaft into a rotational movement of a proximal point of the arm around a rotation axis. The proximal and distal points are situated at opposite ends of the arm. The kinematic chain comprises a link connecting the arm to the support. The link is arranged to guide the proximal point of the arm in rotation around the rotation axis, and to transmit, between the arm and the support, radial orientation forces relative to the rotation axis.
