Claim 11

A single piece neck support being constructed and so shaped as to conform substantially to and overlie and be in contact with the occipital bone between the ears at a first end portion having a first radius of curvature defining a lateral U-shape, the posterior and lateral neck area at a central portion having a second radius of curvature smaller than said first radius of curvature, wherein said central portion extends to a termination thereof on the lateral sides of the neck, and a portion of the suprascapular region at a second end portion having a third radius of curvature larger than said second radius of curvature, said support being semi-rigid, resilient shell preformed to the above shape to support and hold the user's head in a desired position, yet flexible enough to allow forceful movement and position change by the user, said support constructed of a semi-rigid, resiliant material, further having a preformed first transition zone between said first end portion and said central portion having a decreasing radius of curvature in the direction of said central portion and a preformed second transition zone between said central portion and said second end portion and having an increasing radius of curvature in the direction of said second end which assist in providing the required support and rigidity to support the user's head.

Claim 12

The device of claim 9 wherein said shell is adapted to nest with similar shells to increase the rigidity of said support.

Claim 13

The device of claim 10 wherein said nested shells have different lateral dimensions.

Claim 14

The device of claim 10 wherein one or more pads of selected sizes are positioned between said nested shells in selected locations to vary the position of the user's head as desired.

Claim 15

The support of claim 9, wherein a foam pad means is provided on an interior surface of said shell to provide additional support and positive skin contact.

Claim 16

A support according to claim 9, wherein said first end forms an arc of sufficient lateral dimension to engage the occipital and to extend to within three-fourths of an inch of the attachment of the user's ears to the skull.

Claim 17

A support according to claim 14, wherein said central portion forms an arc to provide contact for the entire posterior and lateral neck area.

Claim 18

A cervical and occiptal support for use in supporting a user's head and neck, comprising: a semi-rigid preformed U-shaped shell fabricated of a solid, resiliant material, contoured to fit the occipital bone area of the skull posterolaterally and the neck posterolaterally to the base of the neck having: a first end having a first radius of curvature and extending laterally defining an open arc; a central portion having a second radius of curvature smaller than said first radius of curvature and extending laterally to define an open arc for surrounding and contacting the posterior and lateral neck area from the sub-occipital area to the base of the neck, wherein said central portion extends to a termination thereof on the lateral sides of the neck; a first end portion extending longitudinally from said first end toward said central portion and having a gradually decreasing radius of curvature in the direction of said central portion for laterally supporting and cradling the occipital bone between the ears; a first transition zone between said first end portion and said central portion and having a rapidly decreasing radius of curvature in the direction of said central portion for receiving and longitudinally supporting the occipital bone; a second end having a third radius of curvature larger said second radius of curvature for contacting and resting on the suprascapular region; a second transition zone between said central portion and said second end and having an increasing radius of curvature in the direction of said second end; and a forward edge along a portion of the perimeter of said shell interconnecting said portions and zones; whereby said transition zones add rigidity to said shell in a longitudinal direction and said solid material acts to retain the user's body heat.

Claim 19

A cervical and occiptal support for use in supporting a user's head and neck, comprising: a semi-rigid preformed U-shaped shell fabricated of a solid, resiliant material, contoured to fit the occipital bone area of the skull posterolaterally and the neck posterolaterally to the base of the neck having: a first end having a first radius of curvature and extending laterally defining an open arc; a central portion having a second radius of curvature smaller than said first radius of curvature and extending laterally to define an open arc for surrounding and contacting the posterior and lateral neck area from the sub-occipital area to the base of the neck, wherein said central portion extends to a termination thereof on the lateral sides of the neck; a first end portion extending longitudinally from said first end toward said central portion and having a gradually decreasing radius of curvature in the direction of said central portion for laterally supporting and cradling the occipital bone between the ears; a first transition zone between said first end portion and said central portion and having a rapidly decreasing radius of curvature in the direction of said central portion for receiving and longitudinally supporting the occipital bone; a second end having a third radius of curvature larger said second radius of curvature for contacting and resting on the suprascapular region; a second transition zone between said central portion and said second end and having an increasing radius of curvature in the direction of said second end; and a forward edge along a portion of the perimeter of said shell interconnecting said portions and zones; whereby said transition zones add rigidity to said shell in a longitudinal direction and said solid material acts to retain the user's body heat.
