Abstract
A spring motor having a pot shaped housing in which a flat spiral spring is housed. The flat spiral spring is connected at one outer end to the pot-shaped housing while the inner end is coupled to a shaft or axle. To prevent radial vibrations of individual spring layers when the spring motor is wound or unwound, a damping plate is housed in the pot-shaped housing and held in pressed engagement with a side edge of the flat spiral spring. This spring motor can be combined with the wind-up shaft of roller-blind arrangements for motor vehicles, including fixed roller blinds, storage-area covers, or separating screens.
