Abstract

An orthopedic cervical pillow is disclosed which has a substantially flat undersurface and an uppersurface contoured to form a back engaging portion transitioning into a convex neck engaging portion further transitioning into a head engaging portion. Self-adjusting lift of the back and neck engaging portions is accomplished by means of a relieved section in the undersurface of the pillow generally beneath the head engaging portion. The relieved section extends entirely across the width of the pillow and extends from a forwardmost point underneath the neck engaging portion to approximately halfway under the head engaging portion wherein the contour of the relieved section assumes a substantially vertical contour at its rearmost portion.

Claims

1. In an orthopedic cervical pillow formed of resilient form maintaining cellular material of the type having an undersurface and an uppersurface contoured from front to rear to form a in depth back engaging portion transitioning into a convex neck engaging portion further transitioning into a head engaging portion, the improvement providing for self-adjusting lift of the back and neck engaging portions proportionally responsive to the user'"'"'s head pressure upon the head engaging portion comprising:

a relieved section within the undersurface of the pillow generally beneath the head engaging portion extending from underneath the head engaging portion in a direction toward the rear of the pillow to end at a point under and no more than approximately half the depth of the head engaging portion toward the rear of the pillow and furthe extending in a forward direction to a region beneath the neck engaging portion of the pillow whereby, upon a user'"'"'s head applying pressure upon the head engaging portion, such pressure will proportionately compress the recess downwardly providing adjustment upwardly of the neck and back engaging portions of the pillow.

2. The pillow of claim 1 wherein the relieved section, at its rearmost point beneath the head engaging portion, terminates in a substantially vertical contour.

3. The pillow of claim 2 wherein the relieved section is of uniform cross section across the entire width of the pillow.

4. The pillow of claim 1 wherein the relieved section is of uniform cross section across the entire width of the pillow.
