Abstract
A safety brake for braking a load receiving portion of an elevator has at least one brake wedge that penetrates a gap between a resiliently supported pressure body and a guide rail for the load receiving portion of the elevator and thereby generates a braking force. A stroke limiting device limits the penetration stroke of the brake wedge and controls the braking force in dependence on the retardation value of the load receiving portion of the elevator.
