Patent ID: 7810852

Claim:
An assisted manual actuating device for actuating a controlled member, said controlled member displaceable between a first position and a second position, wherein said first position corresponds to a rest position and said second position corresponds to an actuation position of said controlled member, said device comprising: a control member designed to actuate said controlled member, said control member being displaceable manually along a first actuation travel to reach the actuation position of the controlled member; a transmission system connecting said control member to said controlled member, said transmission comprising: a mechanical element having a first end portion connected to said control member, a middle portion and a second end portion connected to said controlled member; a shape memory element connected to an end of the middle portion and to an end of the second end portion, said shape memory element moving between a non-shortening position and a shortening position; a control unit operatively coupled to a switch that is adapted to detect when said control member reaches said actuation position; electrical-supply means for supplying a current through said shape-memory element to move said shape memory element toward said shortening position, said means activated by said control unit when said control member reaches said actuation position; and an activation device connected to another end of the middle portion and to an end of the first end portion; the activation device having anchoring means for constraining said mechanical transmission when said control member reaches the actuation position in such a way as to enable said transmission system to move only in the direction useful for bringing said controlled member into said second position.
