Patent ID: 7059212

Claim:
An arrestable tensioning device for a parking brake system, comprising: an actuating device; a tensioning element coupled to the actuating device for executing a tensioning motion; a releasable arresting device for the tensioning element, which arresting device comprises a first contour coupled to the tensioning element for movement therewith and an arresting element adapted to interact with the first contour for arresting the tensioning element; a lagging element movable relative to the first contour back and forth between a first relative position enabling an interaction of the arresting element with the first contour and a second relative position preventing an interaction of the arresting element with the first contour; wherein, upon a reversal of motion of the first contour, the lagging element follows said motion of the first contour after a delay in which the lagging element switches from one of said two relative positions to the other of said two relative positions; and wherein a delay device is provided, which interacts in a braking manner with the lagging element.
