ABSTRACT:
A linear actuator is used in an adjustable seat back recliner mechanism to provide infinitely adjustable operation. The actuator rod is maintained in its locked position by the contact of a lower friction surface of the rod with a friction surface on a lower clamp member. Upper clamp members are further seated against an upper surface of the actuator rod. When a sudden force is applied such as in a vehicle collision, an inertial locking element is swung upwardly into contact with the actuator rod to positively lock the actuator rod to the body of the actuator preventing any relative movement.
