ABSTRACT:
The present device is a small "U"-shaped, vinyl covered, foam filled pillow having two side mounted, hinged internal support arms which would adjust left and right with the use of a lock/unlock button. A follower arm is attached between the two support arms causing them to move left and right together, with the result that both would be positioned at the same angle when adjusted. When a patient's head is cradled in the pillow, a dentist or hygienist simply depresses the lock/unlock button, positions the head as desired, and releases the button to lock the arms in that position. Each side of the present invention has a foam head support pad that serves to secure the head and also provides comfort. An internal spring returns the support arms to the center or neutral position when the present invention is not in use. In order to allow the internal spring to return the support arms to the center or neutral position, the dentist or hygienist would depress the lock/unlock button.
