Abstract

A separating mechanism 13 is provided which includes a winding shaft 19 that is rotatably supported in a housing 14. A separating net 15 can be wound on the winding shaft 19 and can be stretched in the space between the housing 14 of the separating mechanism 13 and the roof lining of a passenger car. Since the winding shaft 19 generates a greater torque that the user must counteract with increasing draw-off of the separating net 15, a drive mechanism 18 is provided that provides that from a predetermined draw-out length onward the drive torque for the winding shaft 19 is switched to a reduced level. This switch-over is either brought about as a second, weaker drive spring 39 is activated, or as a second drive spring 93 is switched parallel to the drive spring 38 for the winding shaft 19. The two auxiliary springs 39, 93 operate, however, only over a limited turning range of the winding shaft 19. After this range is exceeded, the full winding force of the main spring 38 becomes effective again in the wind-up process.
