Abstract (en)
[origin: WO2020011841A1] Disclosed is a drive system driving a screen, comprising an actuator for rotationally driving a winding tube (5) acting on the screen, and a compensation spring (7) which is mounted around the actuator (3) and has several turns (70, 71) formed by winding a wire. The drive system comprises at least one plastic ring (9) that is placed between two adjacent turns (70, 71) of the compensation spring (7), and an outer radius (R94) of the ring (9) is larger than a maximum outer radius (R8) of the compensation spring (7).
