Abstract
A safety brake for the load receiving portion of an elevator includes a fixing device that is displaceable relative to the load receiving portion in the direction of the guide rail between two abutments fastened to the load receiving portion. The unlocking of the safety brake after a braking process is achieved by moving the load receiving portion with the assistance of the elevator drive unit oppositely to the direction of movement before the braking process, so that one of the abutments fastened to the load receiving portion strikes the fixing device to unlock it from the guide rail.
