Roller blind system for use as e.g. surveillance roller blind system in area of vehicle window, has adjustment system regulating motor performance depending on actual rolling speed of material or actual motor performance recorded by motor

摘要

The system (20) has a planar material (24) that is removable from a rolling shaft (22). A motor (30) winds the planar material around the rolling shaft. A rolling spring (32) subjects a rolling moment to the rolling shaft in a rolling direction. A delay system subjects the rolling shaft with a delay moment during rolling of planar material. An adjustment system regulates the motor performance of the motor depending on the actual rolling speed of the planar material or actual motor performance recorded by the motor. A controller (40) and a Hall sensor (44) are provided in the adjustment system.
