1. A safety brake for an elevator, the safety brake comprising:
a first braking element;
a first guide element;
an actuating element;
wherein the first braking element is displaceably mounted in a linear bearing on the first guide element, the first guide element being movable between a rest position and a braking initial position;
wherein the actuating element moves the first guide element from the rest position into the braking initial position to activate the safety brake, the first braking element then performing a braking movement from the braking initial position into a braking position, and the braking movement returning the first guide element into the rest position; and
wherein the first guide element is guided during the movement between the rest position and the braking initial position on a first parallelogram guide.
