<p>The roller blind device has a rollable web fastened to a roll shaft (19). A coil spring (46) is coupled kinematically with the roll shaft for pre-tensioning the roll shaft for the purpose of rolling the web on the roll shaft. The coil spring is accommodated in a head-shaped spring housing. A damping disc (47) is held adjacent to a side flank of the coil spring for dampening the oscillations of spring positions of the coil spring. The coil spring is arranged outside the roll shaft and coaxial to the roll shaft. An independent claim is also included for a spring motor arrangement with a coil spring.</p> |
