SPINDLE DRIVE HAVING A REVERSE-LOCK TRANSMISSION

摘要

The invention relates to a further development of a spindle drive (1), and to a lamellar window or a lamellar flap having a spindle drive for moving lamellar elements such that occurring restoring forces and restoring torques can be intercepted better, and in particular without stressing the drive motor. For this purpose, the spindle drive (1) has a specially designed reverse-lock transmission (6) arranged between a drive shaft of a drive motor (3) and a threaded spindle (4).
