Abstract
A tensioner having a backstop device which allows free rotation of the pivot arm in a first direction but controls rotation of the pivot arm in a second, opposite direction. The backstop device permits a predetermined, limited amount of free rotation in the second direction and thereafter, employs a braking device to prevent rotation in the second direction if the torque that acts on the pivot art is less than a predetermined threshold.
