Abstract
The device comprises a manipulator (148) whose body (149) houses deformable positioning transmitter bags (145 to 147) each connected by a corresponding hydraulic circuit to a positioning receiver comprising a deformable bag (130 to 132, 133 to 135), whose increases in volume in response to the compression exerted by the user on at least one of the positioning transmitter bags (145 to 147 control a change of the positioning of at least one controlled member. The device may contain a connector connecting the transmitter bags to the receiver bags, and also path switching hydraulic circuits permitting the selective control of one of two different members by a single manipulator. Application in particular to the control of external rear view mirrors on vehicles.
