Abstract: A safety device for monitoring a movable element, in particular, for elevators, is provided. The safety device includes a speed determination unit for determining the speed of the movable element, a comparator device for comparing a predetermined speed with the determined, actual value, a triggering unit for triggering a braking device, and a distance determination unit for determining the distance of the movable element in relation to a stationary or movable target. The comparator device comprises a memory for storing a maximum admissible speed and at least one nominal distance with an associated nominal speed. The comparator device compares a greatest stored nominal distance with an actual distance indicated by the distance determination unit. When the nominal distance is the same as the actual distance, the comparator device compares the nominal speed associated with the nominal distance with the actual speed registered by the speed determination unit at this point of time.

Abstract: Safety device for monitoring safety distances in relation to destinations and in relation to movable objects as well as different maximum traveling speeds, in particular, for elevators and, preferably, for arrangement on an elevator car, comprising a distance and speed determination unit, a comparator device for comparing the predetermined distance dependent on the destination and having an associated nominal speed with the actual values and a triggering unit for triggering a braking device when the nominal values are exceeded. The aim of the invention defined in the patent claims is to adapt the present-day mechanical speed limiter to the requirements of modern elevator systems as well as to add new functions.
