Abstract

An arrestable tensioning device 10, in particular for a parking brake system, is described. The tensioning device 10 comprises an actuating device 20, a tensioning element 40 coupled to the actuating device 20 for executing a tensioning motion, and a releasable arresting device 60 for the tensioning element 40. The arresting device 60 has a first contour 70 coupled to the tensioning element 40, as well as an arresting element 66, which for arresting the tensioning element 40 interacts with the first contour 70, i.e. for example, is brought into engagement with the first contour 70. A lagging element 64 is provided, which upon a reversal of motion of the first contour 70 follows on after a time delay and in said case is movable relative to the first contour 70 back and forth between a first relative position enabling e.g. an engagement of the arresting element 66 into the first contour 70 and a second relative position preventing an engagement of the arresting element 66 into the first contour 70.
