<p>The drive gear (1) includes a flexible shaft (4) sliding in a fixed guide (2) and having an end (6) connected to the glass pane (5). The guide (2) includes an internally threaded sleeve (8) adapted to engage the flexible shaft (4), which in turn has an outer threading (4a) so that a rotation of the sleeve (8) corresponds to an axial translation of the flexible shaft (4), the sleeve (8) being actuated by a motor (3). The flexible shaft (4,6) is monolithically made of plastics by injection molding.</p> |
