Abstract

A vehicle head restraint assembly has a guide member mounted to a vehicle seat back. A head restraint is mounted to another guide member that has notches and is mounted to the first guide member for movement in a fore and aft direction. A biasing member biases a locking mechanism that is mounted to the first guide member into engagement with the notches. A first actuator is mounted to the first guide member for actuation in a lateral direction from one lateral side such that linear actuation of a first actuator compresses the biasing member to disengage the locking mechanism from the notches to permit adjustment of the fore and aft position of the head restraint. A second actuator is mounted to the first guide member for actuation in a direction perpendicular to the lateral direction and cooperates with the first actuator for actuating the first actuator.
