<p>The actuator includes a tubular guide (18) with two parallel side-by-side rectilinear portions (22 and 24) and a flexible rack (16) formed of a spirally wound metal wire wound about a flexible core housed partly in one rectilinear portion and partly in the other. A geared motor system (2, 8, 10, and 12) includes a gearwheel (14) engaging with the rack via an aperture (28) provided in one of the rectilinear portions. One hanger (34) fixed to the rack emerges via an appendix (32) through a continuous longitudinal slot (30) in one of the portions. Members (36) mechanically connect the hanger appendix (32) to the element (26) to be moved.</p> |
