ABSTRACT:
The present invention is directed to a powered actuation mechanism for a reclining chair. The powered drive mechanism rotates a drive link which engages a follower link to extend the leg rest assembly. A biasing mechanism is coupled to the leg rest assembly to retract the leg rest assembly. In this manner, the leg rest assembly cannot be fully retract when an obstruction with the leg rest assembly is encountered.
