Abstract (en)
[origin: WO2009092438A1] The invention relates to a crash safety device having a safety rope (105) wound onto a drum, a recuperating spring tensioned by the drum during the winding of the rope, and a locking device for blocking the drum from rotation in the rope unwinding direction during the crash of a person secured by the rope. A rope drive mechanism is provided in order to unwind the rope (105) from the drum and to slowly move the rope end having a hook (290) attached thereto toward such that a person can hook onto the safety rope (105). The drive mechanism has a motor (140) driving a rope drive wheel (210) via a freewheel (200) for lowering the rope end having the hook (290). In order to rewind the rope, the motor (140) is operated in a reverse direction of rotation at a controlled rotational speed in order to limit the speed at which the rope (105) is pulled up by the tensioned recuperating spring.
