摘要

Safety device (1) comprises a sensor unit (8) for acquiring the relative movement of a functional part (2) and interacting with a retaining device (7). The retaining device is automatically activated into a safety position when a speed theoretical value is exceeded. Preferred Features: The sensor unit has an adjusting element on its outlet side and is connected to a control unit (11) for displacing the retaining device by a signal emitter. The retaining device can be directly transferred into the safety position using the adjusting element.
