Disclosed is an arrestable tensioning device (10), particularly for a parking brake system. The inventive tensioning device (10) comprises an actuating device (20), a tensioning element (40) coupled to the actuating device (20) for carrying out a tensioning movement, and a removable arresting device (60) for the tensioning element (40). The arresting device (60) is provided with a first profile (70) that is coupled to the tensioning element (40) and an arresting element (66) interacting, e.g. meshing, with the first profile (70) so as to arrest the tensioning element (40). The inventive arrestable tensioning device also comprises a lagging element (64) which follows in a delayed manner when the movement of the first profile (70) is reversed and which moves back and forth in relation to the first profile (70) between a first relative position, in which meshing of the arresting element (66) with the first profile (70) is made possible, for example, and a second relative position, in which meshing of the arresting element (66) with the first profile (70) is prevented. |
