Abstract: A retractable barrier includes a rollup or otherwise retractable panel that can extend between two spaced apart support members. When not in use, the panel can retract onto one of the support members to permit passage. The barrier provides substantial impact resistance by having the reactive force of the impact transfer directly between the barrier's retractable panel and its support members without having to rely on the strength of the panel's take-up roller or the strength of the roller's anti-rotation mechanism. This can be accomplished by having a slot-engaging stop member mounted directly to the panel itself. The stop member is preferably a pipe, rod, bar or some other vertically elongate member that can broadly distribute an impact reactive force over the height of the panel. In some embodiments, the barrier can be set for various doorway widths by simply repositioning the stop member's location on the retractable panel.

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.
