Articulating headrest assembly

A headrest assembly rotatable to a plurality of positions, said headrest assembly comprising:

• a support defining a horizontal axis;
• a shell rotatably mounted to said support about said horizontal axis;
• a plurality of notches defined by said support and each associated with one of the plurality of positions about said horizontal axis;
• a lever mounted to said shell about a pivot axis and having a locking portion rotatable about said pivot axis and partially disposed in one of said plurality of notches for locking said shell in one of the plurality of positions to prevent movement of said shell about said horizontal axis;
• and
• an actuator mounted to said shell and abutting said lever to rotate said locking portion of said lever about said pivot axis in a direction transverse to said horizontal axis for moving said locking portion out of one of said plurality of notches to allow said shell to rotate about said horizontal axis when said actuator is actuated and for moving said locking portion into one of said plurality of notches to prevent said shell from rotating about said horizontal axis when said actuator is deactivated.
