Abstract
A releasable backstopping clutch is provided with a safety mechanism to prevent uncontrolled release of the clutch. A support structure is fixed against rotation and releaseably coupled to the one of the inner or outer members of the backstopping clutch. The support structure inhibits rotation of the member when coupled to the member and permits rotation of the member when uncoupled from the member to release the clutch. A sensor is configured to generate a signal indicative of a characteristic associated with movement of the member and a controller is configured to cause recoupling of the support structure and the member if the characteristic meets a predetermined condition.
