Abstract
A head restraint assembly includes a post assembly which has a first post section, a second post section, and a cross member section connecting the first post section and the second post section. The first post section and the second post section are adapted to engage a vehicle seat. The head restraint includes a bun moveably attached to the post assembly, a first gear, and a motor that rotates the first gear in a clockwise or counter-clockwise direction. Rotation of the first gear drives a second gear which drives a third gear. Rotation of the second gear in a first direction causes movement of the bun to a tilted position while movement of the second gear in a second direction causes movement of the bun to an upright position.
