A head positioning device comprising: (A) a head support that is configured for supporting a patient's head; and (B) a sliding joint that is connected to allow the head support to be moved about a virtual axis of rotation while the head support is supporting the patient's head, wherein the virtual axis of rotation is spaced apart from the sliding joint. The head positioning device may include a head restraint for maintaining the patient's head in a substantially fixed relation to the head support as the head support is moved about the virtual axis of rotation. In one embodiment, the head restraint comprises a hook member that is configured for hookedly engaging a curved portion of the patient's face.

I claim: 1. A head positioning device comprising: a head support that is configured for supporting a patient's head, said head support being configured for engaging a rear portion of said patient's head; and a head restraint disposed adjacent said head support, said head restraint comprising a hook member that is configured for: (A) hookedly engaging a curved portion of said patient's face; and (B) exerting a force adjacent said curved portion of said patient's face, said force being sufficient to rotate said patient's head so that said patient's forehead moves away from said patient's chest. 2. The head positioning device of claim 1, wherein: said head positioning device further comprises a sliding joint that is disposed adjacent said head support and adapted to allow said head support to move along a substantially arcuate path while said head support is supporting said patient's head; and said hook member is configured for exerting said force adjacent said curved portion of said patient's face in response to said head support being moved along said substantially arcuate path. 3. The head positioning device of claim 2, wherein said arcuate path lies substantially along the circumference of a circle having its center along an axis that extends through a mastoid region of said patient's head. 4. The head positioning device of claim 3, wherein said circle is substantially parallel to said axis. 5. The head positioning device of claim 2, wherein said force is sufficient to maintain said patient's head in a sniffing position while said patient is being intubated. 6. The head positioning device of claim 2, wherein said hook member is configured for hookedly engaging said patient's glabella. 7. The head positioning device of claim 6, wherein said hook member is configured for exerting said force adjacent said patient's glabella. 8. The head positioning device of claim 7, wherein said force is sufficient to maintain said patient's head in a sniffing position while said patient is being intubated. 9. The head positioning device of claim 2, wherein said head restraint further comprises a head restraining portion that is configured to extend around at least a portion of said patient's forehead while said head support is being moved along said substantially arcuate path. 10. The head positioning device of claim 9, wherein said head restraint further comprises a padding portion that is configured for being disposed between said patient's forehead and said head restraining portion while said head support is being moved along said substantially arcuate path. 11. The head positioning device of claim 9, wherein said head restraining portion is substantially rigid. 12. The head positioning device of claim 1, wherein said force is sufficient to rotate said patient's head about a virtual axis of rotation between a non-extended position and a "sniffing" position. 13. The head positioning device of claim 12, wherein said virtual axis of rotation extends through a mastoid region of said patient's head. 14. The head positioning device of claim 12, wherein said virtual axis of rotation extends proximate a mastoid region of said patient's head. 15. A head positioning device comprising: a head support that is configured for supporting a patient's head, said head support being configured for engaging a rear portion of said patient's head; and a head restraint disposed adjacent said head support, said head restraint being configured for: (A) engaging a portion of said patient's face; and (B) exerting a force adjacent said portion of said patient's face, said force being sufficient to rotate said patient's head into a sniffing position while said head support is supporting said patient's head. 16. The head positioning device of claim 15, wherein said head restraint comprises a head restraining portion that is configured: (A) to extend around at least a portion of said patient's forehead while said head positioning device is being used to move said patient's head into said sniffing position; and (B) to maintain said patient's head in a substantially fixed orientation relative to said head support while said head positioning device is being used to move said patient's head into said sniffing position. 17. The head positioning device of claim 16, wherein said head restraining portion is substantially rigid. 18. The head positioning device of claim 16, wherein said head restraining portion is configured to extend substantially entirely around said patient's forehead while said head positioning device is being used to move said patient's head into said sniffing position. 19. The head positioning device of claim 18, wherein said head restraining portion is configured to maintain said patient's head in said sniffing position while said patient is being intubated. 20. The head positioning device of claim 19, wherein said head restraint comprises a hook member that is configured: (A) to hookedly engage a portion of said patient's face; and (B) to exert a force on said portion of said patient's face, said force being sufficient to facilitate moving said patient's head into said sniffing position. 21. The head positioning device of claim 20, wherein said head positioning device further comprises: a base member that is spaced apart from said head support; and an elevating mechanism that is adapted to move said head support between: (A) a first position in which said head support is spaced apart from said base member by a first distance, and (B) a second position in which said head support is spaced apart from said base member by a second distance. 22. The head positioning device of claim 15, wherein: said head positioning device further comprises a sliding joint that is disposed adjacent said head support and adapted to allow said head support to move along a substantially arcuate path while said head support is supporting said patient's head. 23. The head positioning device of claim 22, wherein said arcuate path substantially lies along the circumference of a circle having its center along an axis that extends through a mastoid region of said patient's head. 24. The head positioning device of claim 23, wherein said circle is substantially perpendicular to said axis. 25. The head positioning device of claim 15, wherein said force is sufficient to rotate said patient's head about a virtual axis of rotation between a non-extended position and a "sniffing" position. 26. The head positioning device of claim 25, wherein said virtual axis of rotation extends through a mastoid region of said patient's head. 27. The head positioning device of claim 25, wherein said virtual axis of rotation extends proximate a mastoid region of said patient's head.
