    摘要: A safety catch device for elevator cars guided on at least one guide rail includes a braking device acting on the at least one guide rail for braking the elevator car and a control device for controlling the braking force of the braking device in dependence on the load and/or deceleration. The control device includes a control mass which is influenced by the acceleration of the elevator car and a brake spring which is deflected in accordance with the position of the control mass. The brake spring is coupled to the control mass and the braking device in such a way that a reduced braking force is applied by the braking device on the at least one guide rail in the case of a high deceleration of the elevator car and an increased braking force is applied by the braking device on the at least one guide rail in the case of a lower deceleration of the elevator car.
