Abstract
A device for latching a rotatable shaft. A lever arm is coupled with the shaft and rotates the shaft between a first and second positions when the lever arm rotates between respective first and second positions. A latching device latches the lever arm, in response to receiving an activation signal, when the lever arm is in the first position. The latching device holds the lever arm in the first position. A biasing device is coupled with the lever arm and exerts a biasing force on the lever arm that biases the lever arm towards the second position.
