- the horizontally extending in the installed state axis A is symmetrical between the sliding surfaces 14 and 16.
- the braking surfaces 18 and 19 against the adjacent sliding surfaces 14 and 16 in the active position slightly inwardly and thus cause the pressing of the guide rail to reduce the unwanted vertical vibrations of the elevator car.
- the rectangular braking surfaces have a higher coefficient of friction than the sliding surfaces.
- the braking surfaces 18 and 19 are arranged offset with respect to the running direction z.
- the lever arrangement 38 can be moved in such a way that there is a minimal clearance to the guide surfaces of the guide rail in the rest position.

- the preferably connected to the engine via a gear stub axle 43 then undergoes a 180 ° - rotation about the R axis, whereby the brake element is displaced against the guide surface 12.
- the thus shifted brake element is shown in FIG.
- the brake element 7 has a non-circular bearing opening 44 cooperating with the cylindrical circumference of the eccentric body.
- the elastic elements 50 are compressed on the opposite side and the braking surface 20 against which the guide surface 11 is pressed.
- the braking element 7 could also be moved by means of a linear drive, a lever mechanism or even using hydraulic or pneumatic means.
- the respective braking surfaces lie between two sliding surface sections and thus in total in each case in a sliding surface.
- the damping region is also in the sliding surface, in which case the damping region is part of the sliding surface, for which reason, therefore, the term sliding surface portion was used.
- the damping area for reducing the vertical vibrations of the elevator car during a standstill does not necessarily have to be arranged in the sliding surfaces.
