Abstract (en)
[origin: WO2020011861A1] Disclosed is a drive system (1) driving a screen (6), comprising an actuator (3) for rotationally driving a winding shaft (5) associated with the screen (6), and a compensation spring (7). The compensation spring (7) has a first end (71) that is connected to a stationary part of the actuator (3), and a second end (72) that is connected to a rotatable part of the actuator (3) or to the winding shaft (5). The drive system (1) comprises a housing (30) enclosing the actuator (3), and an attachment part (9) for attaching the first end (71) of the compensation spring (7), the attachment part (9) comprising a body having a substantially cylindrical inner and outer shape, said attachment part (9) surrounding the tubular housing (30) and being secured to the tubular housing (30) such that the attachment part (9) is prevented from rotating and moving translationally along a central axis (X) of the tubular housing (30).
