Abstract

The neck curvature alignment device (10) comprises a framework (12) including a base portion (14) adapted to be supported on a generally planar surface and having an upper surface (18), and a pivot portion (16) having an outer surface (49) and being pivotally connected to the base portion; a moving mechanism (52) situated between the base portion and the pivot portion for moving the pivot portion away from the base portion; a device (58) for actuating the moving mechanism; a head and neck receiving device (50) mounted on the upper surface of the base portion and having a structure (72) for engaging and bearing against the occipital bone of a patient's head, whereby operation of the moving mechanism will cause the pivot portion to move away from the base portion to cause the head and neck receiving portion to act in an arcuate direction against a patient's neck and head.

Claims

AMENDED CLAIMS[reced ed by the International Bureau on 3 July 1997 (03 07 97), original claims 1 , 2, 9 and 12-14 amended, original claims 15-17 cancelled, remaining claims unchanged (3 pages)]
1. (New) A neck curvature alignment device for use by a person and comprising: a framework including a base portion which is supported on a generally planar surface and which has an upper surface and a pivot portion, which has an outer surface and which is pivotally connected at one end by a pivot connection to said base portion, said framework being capable of being positioned beneath a person's head for pivotal movement in an arcuate direction from the back of the person's neck upwardly toward the person's forehead; a moving mechanism situated between said base portion and said pivot portion for moving said pivot portion away from said base portion and, when positioned beneath the persons head, in a direction toward the person's forehead; means for actuating said moving mechanism; and, a head and neck receiving device having an outer end and an inner end, a neck receiving portion and a head receiving portion between said neck receiving portion and said outer end and being mounted on said outer surface of said pivot portion and having support structure including a lift surface for engaging and bearing against the occipital bone of a person's head, and said pivot connection being located outwardly of said outer end and of said head receiving portion, whereby operation of said moving mechanism will cause said pivot portion to move away from said base portion to cause said head and neck receiving device to act in an arcuate direction against a person's neck and head, the arcuate direction being upwardly from the back of the person's neck and in an arc toward the person's forehead so as to push the person's head upwardly and horizontally away from the persons body and, at the same time, exert a stretching force on the person's neck.
2. (Amended) The neck curvature alignment device of claim 1 wherein said head and neck receiving device has contoured surfaces for receiving and supporting a user's or patient's head and neck and said support structure includes a ridge and adjacent thereto, said lift surface for engaging against the occipital bone of a patient's head received in said head and neck receiving device.
3. (Same) The neck curvature alignment device of claim 1 further comprising a head strap connected to said head and neck device and about a user's or patient's head.
4. (Same) The neck curvature alignment device of claim 1 wherein said base portion includes first and second legs interconnected by a transverse cross-leg and a hinge at one end of each of said first and second legs.
5. (Same) The neck curvature alignment device of claim 4 wherein the other end of each of said first and second legs has a slightly S or Z-shape to provide an offset end portion which is adapted to rest on a horizontal surface.
6. (Same) The neck curvature alignment device of claim 4 wherein the angle of each of said first and second legs to a supporting surface at said hinges is between 2° and 6°.
7. (Same) The neck curvature alignment device of claim 4 wherein said pivot portion comprises first and second legs each pivotally connected, respectively, to said first and second legs of said base portion.
8. (Same) The neck curvature alignment device of claim 7 wherein said pivot portion has, at its outer end thereof, a cross-plate so as to form said pivot portion with a generally C-shape and said head and neck receiving device is mounted to an outer surface of said cross-plate.
9. (Amended) The neck curvature alignment device of claim 1 wherein said moving mechanism includes a bellows which is mounted to an upper surface of a transverse leg of said base portion and is generally rectangular in shape.
10. (Same) The neck curvature alignment device of claim 9 wherein said bellows is made of an elastomeric material and is of such a size that it can move said pivot portion upwardly and outwardly up to 45° away from said base portion.
11. (Same) The neck curvature alignment device of claim 1 wherein said moving mechanism for moving said pivot portion away from said base portion includes a bellows fixed to an upper surface of said base portion and said actuating means includes a pump for pumping a gas into said bellows.
12. (New) The neck curvature alignment device of claim 1 wherein the radius of an arcuate force applied at said lift surface from said pivot connection to the area where said lift surface acts against the person's head is between three inches and ten inches.
13. (New) The neck curvature alignment device of claim 7 wherein said pivot portion includes a transversely extending support plate at its outer end, wherein the distance from said pivot connection between said first and second legs of said pivot portion and said first and second legs of said base portion to the area of said support structure on said head and neck receiving device which engages against the occipital bone of the user/patient is between 3 inches and 10 inches.
14. (New) The neck curvature alignment device of claim 13 wherein said distance is between 5 inches and 6 inches.
