An elevator system (50) comprises a guide rail (56; 110), an elevator car (54), a safety brake actuator (100; 200; 300; 400) and a safety brake (58). The safety brake actuator (100; 200; 300; 400) and the safety brake (58) are mounted to the elevator car (54) to move along the guide rail (56; 110) with the elevator car (54) in use. The safety brake actuator (100; 200; 300; 400) comprises an actuation mechanism (102) configured in use to actuate the engagement of the safety brake (58) against the guide rail (56; 110). The safety brake actuator (100; 200; 300; 400) also comprises a proximal surface (117; 203; 302), wherein the safety brake actuator (100; 200; 300; 400) is mounted adjacent to the guide rail (56; 110) with the proximal surface (117; 203; 302) facing the guide rail (56; 110) and spaced from the guide rail (56; 110) to define a clearance gap (118) between the guide rail (56; 110) and the proximal surface (117; 203; 302) of the safety brake actuator (100; 200; 300; 400). The safety brake actuator (100; 200; 300; 400) also comprises an object-diverting arrangement (122; 204; 304; 402) positioned relative to the clearance gap (118) to prevent or impede the entry of foreign objects into the clearance gap (118).
