The safety gear serves for braking an elevator car in an elevator system with a guide rail exhibiting an oblong guide flange. The safety gear comprises a holding device (1), which carries a retaining element (4, 6) and an abutment (5), whereby, in operation, the safety gear is arranged in such a manner that the guide flange is positioned between the retaining element (4, 6) and the abutment (5). A mechanism (8) is available, which squeezes, when braking, a braking element in the form of a blocking roller (7) between the guide flange and the abutment (5). The mechanism (8), cooperating with an electromagnet (3), exhibits a suspension (12) and in such suspension the braking element (7) is movably placed and can be moved in a controlled way between different positions, which are to be assigned to different operating conditions of the safety gear.
