Abstract
A seat recliner mechanism for controllably adjusting the angular position of a seat back relative to a seat member in response to actuation by a seat occupant is disclosed. The seat recliner mechanism includes a rod adapted to be operatively connected to one of the seat back and the seat member. The recliner mechanism is pivotally connected to the other of the seat back or the seat member and is configured to receive a portion of the rod for linear movement relative thereto. The mechanism includes a split nut assembly engaging the rod which is movable between a first position inhibiting linear movement of the rod and a second position permitting linear movement of the rod. A clamp assembly having a passage for encasing the split nut assembly is provided and which has at least one pivotable lock clamp member adapted to reduce the cross-section of the passage when pivoted in a first direction and to enlarge the cross-section when pivoted in a second direction. The clamp assembly includes an actuation device for pivoting the lock clamp member in the second direction to move the split nut assembly from the first position to the second position.
