Abstract
A triggering unit for actuating an elevator braking device, having a triggering base body, a trigger, a contact device and a coupling link. The contact device comprises a swivel lever and at least two contact elements, the swivel lever being pivotably anchored on one side of the guide rail and bearing a first contact element in the region between its anchoring and the guide rail, wherein the first and the second contact elements are arranged on the swivel lever in such a manner that the swivel lever automatically pulls itself against the guide rail under the influence of the forces occurring between the contact elements and the guide rail in the triggered state, and the swivel lever is anchored to the triggering base body such that it executes a movement which generates tension or pressure at the coupling link, so that the coupling link actuates the elevator braking device.
