Abstract
A triggering unit for actuating an elevator braking device, having a triggering base body which can be mounted on an elevator car, a trigger, a contact element and a coupling link via which the contact element can be connected to an elevator braking device, the triggering unit keeps the contact element at a distance from the guide rail in the untriggered state and brings it into frictional contact with the rail in the triggered state, so that the contact element moves along a gap between the triggering base body and the guide rail, carries along the coupling link and causes the elevator braking device to respond automatically due to the movement of the coupling link, wherein the triggering unit can be mounted separately on the elevator car at a distance from the elevator braking device and is connected to the elevator braking device exclusively via the coupling link.
