Patent ID: 7621010

Claim:
A dental chair overlay comprising: a body support having a superior end and dorsal and ventral surfaces, the distance between the dorsal and ventral surfaces defining a generally uniform thickness for the body support, the body support comprised of a material that provides resistance to patient lateral movements and positions a patient towards the longitudinal axis of the body support; a head support attached to the superior end of the body support and having dorsal and ventral surfaces the distance between the dorsal and ventral surfaces defining a thickness of the head support, the head support being thicker at its lateral edges than in the region between the lateral edges, thereby forming a cupped surface for receiving the head of a patient, the head support being thicker at an area adjacent to the body support, than at an area further away from the area adjacent to the body support, thereby defining a means for supporting a patient's neck; wherein the thickness of the body support is greater than the thickness of the head support, such that the airway of a patient lying on the dental chair overlay is urged open.
