Abstract
In the specification and drawings, an apparatus and method for operating a take-up mechanism is described and shown. The take-up mechanism includes a gear, a motor configured for engagement with the gear, and a manual input shaft configured for engagement with the gear. In a first mode of operation, the gear transmits rotation from the motor, and in a second mode of operation, the gear transmits rotation from the manual input shaft. In an alternate embodiment, the take-up mechanism may include a plate between the manual input shaft and the gear. The plate may be configured to transfer rotation and torque from the manual input shaft to the gear, or inhibit the transfer of rotation and torque from the gear to the manual input shaft. The method for operating the take-up mechanism uses a motor and a manual input shaft connected to a gear to operate the take-up mechanism in the first and second modes. The motor is continuously engaged with the gear during at least the second mode of operation when setting and releasing the take-up mechanism.
