Abstract

A head restraint assembly is provided with a head restraint frame mounted to a post for movement along the post for adjustment relative to a vehicle seat. The head restraint frame has a contact surface. A biasing member is mounted to the head restraint frame for movement relative to the head restraint frame to maintain the head restraint frame in a locked condition along the post. An actuation member is mounted to the head restraint frame for movement relative to the head restraint frame. The actuation member cooperates with the biasing member such that movement of the actuation member moves the biasing member, thereby disengaging the biasing member from the post to permit movement of the head restraint along the post such that the biasing member engages the contact surface in the second position to provide feedback to the user of an unlocked condition of the head restraint frame.
