Abstract
Abstract A trigger release mechanism is provided for a reclining chair especially of the type which is locked in a normal or closed position but which will automatically move into a reclining TV position upon release of a lock mechanism. The trigger release mechanism includes a small lever or trigger mounted on one side of the chair to be conveniently engaged by the chair occupant. A connecting member such as a cable depends from the trigger and is connected to the lock mechanism to actuate it to permit the chair to move to the TV position wherein the footrest is extended.
