Claim:
1. An elevator including a car which is guided at guide rails and a safety brake arranged at the car for exertion of a braking force on the guide rails in an event of non-compliance of a safety criterion, the safety brake comprising: a brake housing having an opening of wedge-shaped form into which at least a part of one of the guide rails is introduced; a brake body positioned in the wedge-shaped opening between a surface of the brake housing bounding the wedge-shaped opening and a guide surface of the one guide rail; an activating mechanism for transmitting an activation force to the brake body to press the brake body against the surface bounding the wedge-shaped opening and the guide surface; a release mechanism connected with the brake body for holding the brake body in a rest position against the activation force, the release mechanism including an articulated arm movable between an extended position and a folded position, wherein the articulated arm in the extended position holds the brake body in the rest position and in the folded position releases the activation force for transmission to the brake body, and the activating mechanism including a lever arm connected with the brake body for transmitting the activation force to the brake body, the lever arm being connected with the articulated arm whereby the articulated arm in the extended position holds the lever arm in the rest position against the activation force; wherein the lever arm is connected with a spring of the activating mechanism, which is biased to transmit the activation force to the lever arm; and wherein a longitudinal axis of the articulated arm and a longitudinal axis of the spring are oriented in alignment to each other.
