Abstract
Abstract A portable device for recumbency of the head and neck providing support for the same while travelling or in other situations where discomfort arises from lack of adequate support. The device is provided with a surface having a generally concave shape with respect to a vertical axis of curvature corresponding approximately to the central vertebral axis of the neck. The concave shape is fashioned so that it has symmetrical left and right halves, opposing areas of which are designed to exert gentle pressure in the vicinity of the mastoid processes of the head, a region near the base of the head, and located at the sides thereof almost at the rear. There are two embodiments of the device, one a padded resilient sheet curved to provide the support surface and a second in the form of an inflatable pillow.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
144 words
A device for recumbency of the head and neck, such device comprising a supporting surface having a generally concave shape with respect to a vertical axis of curvature that corresponds approximately to the central vertebral axis of the neck so that (a) the generally concave shape has left and right halves that are symmetrical about the line of their junction and also so that (b) symmetrically opposed areas in the vicinity of non-adjacent edges of each half exert gentle pressure in the vicinity of the mastoid processes of the head, wherein the surface also has a generally convex shape with respect to a horizontal axis, such axis intersecting the vertical axis of curvature, so that the generally convex shape conforms generally to at least the upper portion of the nape of the neck and the lower portion of the occipital bone of the head.
Claim 2
Independent Claim
144 words
A device for recumbency of the head and neck, such device comprising a supporting surface having a generally concave shape with respect to a vertical axis of curvature that corresponds approximately to the central vertebral axis of the neck so that (a) the generally concave shape has left and right halves that are symmetrical about the line of their junction and also so that (b) symmetrically opposed areas in the vicinity of non-adjacent edges of each half exert gentle pressure in the vicinity of the mastoid processes of the head, wherein the surface also has a generally convex shape with respect to a horizontal axis, such axis intersecting the vertical axis of curvature, so that the generally convex shape conforms generally to at least the upper portion of the nape of the neck and the lower portion of the occipital bone of the head.
Claim 3
Dependent Claim
18 words
The device of claim 1, further comprising an inflatable volume, which when inflated has the previously described surface.
Claim 4
Independent Claim
16 words
The device of clam 1, further comprising a stuffed pillow which has the previously described surface.
Claim 5
Independent Claim
16 words
The device of clam 1, further comprising a stuffed pillow which has the previously described surface.
Claim 6
Dependent Claim
181 words
The device of claim 1, further comprising a sheet of material having a generally concave shape with respect to a vertical axis of curvature that corresponds to the central vertebral axis of the neck so that (a) the generally concave shape has left and right halves that are symmetrical about the line of their junction and also so that (b) symmetrically opposed areas in the vicinity of non-adjacent edges of each half exert gentle pressure in the vicinity of the mastoid processes of the head, wherein the sheet of material also has a generally convex shape with respect to a horizontal axis, such axis intersecting the vertical axis of curvature, so that the generally convex shape conforms generally to at least the upper portion of the nape of the neck and the lower portion of the occipital bone of the head, wherein the surface of such material facing the vertical axis of curvature is hereinafter referred to as the "inside" and the surface of such material facing away from the vertical axis of curvature is hereinafter referred to as the "outside".
Claim 7
Dependent Claim
19 words
The device of claim 4, further comprising padding on at least a portion of the inside of the sheet.
Claim 8
Dependent Claim
76 words
The device of claim 4, further comprising an upward extension of the surface from the generally convex shape, in a direction generally parallel to the vertical axis; and first means, affixed to the device proximate to the lower portion of the convex shape, for causing the shape to press gently against the nape of the neck and lower portion of the occipital bone when the outside of the upward extension is placed against a vertical surface.
Claim 9
Dependent Claim
36 words
The device of claim 6, wherein the first means comprises a resilient material so as to permit engagement of the convex shape yieldingly against the nape of the neck and lower portion of the occipital bone.
Claim 10
Dependent Claim
22 words
The device of claim 7, wherein the material is resilient and first means is formed as part of the sheet of material.
Claim 11
Dependent Claim
34 words
The device of claim 8, wherein the first means comprises a curved extension of the generally concave shape, such extension beginning in a generally downward direction and forming an arc in excess of 180°.
