Abstract
A safety brake includes a first brake element, a first guide element, and an actuating element. The first brake element is mounted in a displaceable manner in a linear bearing on the first guide element. The first guide element can be moved between a rest position and a braking initial position. The actuating element is designed to move the first guide element from the rest position into the braking initial position, more particularly to activate the safety brake. The first brake element can carry out a braking movement from the braking initial position into a braking position. The braking movement returns the first guide element to the rest position. The first guide element is guided on a first parallelogram guide.
