Abstract
A damper unit for an elevator for reducing vertical vibrations of an elevator car of the elevator during a standstill includes a stamp-like acting element that acts on an end-face guide surface of a guide rail. The acting element is spaced from the guide rail in an idle position and can be connected slip-free to the guide rail by an eccentric drive in an active position. Force transmitting elements containing a shock damper for damping the motions of the elevator car during a standstill of the car adjoin the acting element.
