Definitions

  • the present disclosure relates to a cushion and more particularly to a spine support insert that can be disposed in the cushion.
  • pillow cases provide numerous advantages to end-users of pillows.
  • One advantage of using a pillow with a pillow case is that the surface of the pillow can be protected from various oils produced by the human body, specifically, the human head and hair, thus providing a cleaner and more hygienic surface for a user to rest his/her head.
  • a pillow case can be washed from time to time.
  • Another advantage is that a pillow case can be made of a material that is more comfortable for contact with human skin than the material from which the pillow is produced.
  • a pillow case may provide a more aesthetically pleasing appearance to the pillow.
  • Certain pillows designed for aligning the cervical spine feature a head well, that is, a recessed portion of the pillow designed to accommodate a user's head.
  • a head well aids in aligning the cervical spine while sleeping by allowing the head to be placed in an optimal position for cervical contour.
  • pillow cases have not been developed to adequately accommodate a head well in a pillow. This leads to a problem referred to as "hammocking," wherein a pillow case does not stretch to contact a bottom surface of the head well of a pillow such that empty space remains between the pillow case and the bottom surface of the head well, leading the pillow case to "hammock" between sides of the head well. This prevents the full benefits of the head well from being realized as the head never reaches a position optimal for cervical contour.
  • current pillows designed to align the cervical spine have several problems which hinder their effectiveness.
  • Third, current pillows featuring head wells may encounter the hammocking problem described above when used with conventional pillow cases.
  • the present disclosure relates to a cushion and more particularly to a pillow providing cervical alignment by way of a cervical spine support that is positioned along a major axis of the pillow, and that can be rotated around the major axis.
  • the pillow includes a head well portion having a lower surface with a depth of 0.8 to 2.7 inches from a top surface of the pillow to further aid in cervical alignment by allowing a user's head to be placed in an optimal position for cervical counter.
  • the pillow has a total thickness of 5 to 6.25 inches from a top surface of the pillow to a bottom surface of the pillow.
  • the pillow may be rectangular and may have a length of 20 to 24 inches and a width of 11 to 16 inches.
  • the pillow further includes a substantially hollow compartment in which the adjustable cervical spine support can be disposed therein. A circumferential difference between the cervical spine support and a surface of the hollow cavity can be from 1 ⁇ m to 1 cm.
  • the pillow can be disposed in a hollow cavity of a pillow case comprising a front portion comprising a front portion and a back portion, the front portion further comprising a central region and a non-central region.
  • the central region is made of a single layer of a 4-way stretch material and the non-central region and the back portion are made of a non-stretchable material.
  • the non-stretchable material may be porous.
  • the front portion and the back portion are attached perimetrically and define the hollow cavity.
  • the central region of the pillow case is aligned with the head well portion of the pillow. When a user's head rests on the central region of the pillow case, the central region stretches to contact the lower surface of the head well portion.
  • the cervical spine support may comprise a first segment made of a first material having a first density and a second segment made of a second material having a second density.
  • the first segment and the second segment may have different geometries.
  • the cervical spine support can be adjusted such that the different segments are positioned adjacent to the cervical spine of the user, thus providing different levels of firmness.
  • the cervical spine support is disposed in the substantially hollow compartment of the pillow and runs along a major axis of the pillow.
  • the length of the cervical spine support can be 20 to 28 inches.
  • the cervical spine support is cylindrical and has a diameter of 3 to 6 inches.
  • the adjustable cervical spine support can be outfitted with different functional components designed to increase user comfort.
  • the functional component is a speaker embedded in the cervical spine support.
  • the speaker may be configured to emit sounds conducive to user relaxation.
  • the functional component is a motor embedded in the cervical spine support coupled to at least one massage node.
  • the motor can cause the at least one massage node to rotate or vibrate, thus providing a massage to a user while he or she lays on the pillow.
  • the functional component may be a porous or vented compartment embedded in or attached to the cervical spine support. A fragrant material may be disposed in the porous or vented compartment, thus providing a user with a pleasing olfactory sensation while using the pillow.
  • functional component may be a compartment embedded in or attached to the cervical spine support.
  • a heat source may be disposed in the compartment to provide heat to the cervical spine area of a user.
  • a pack filled with a gel or liquid may be disposed in the compartment, wherein the gel or liquid is chilled, such as being frozen prior to insertion into the pillow, thus providing cooling to the cervical spine area of a user.
  • the functional component can be inserted into the second segment of the cervical spine support. In another embodiment, the functional component can be inserted into a cylindrical housing with a soft outer shell.
  • a cervical spine support for a pillow may be made by shaping a first segment from a first material to form a section of a cylinder.
  • a second segment may be shaped from a second material, thereby forming a second section of a cylinder.
  • the second segment may be shaped to have a different geometry than the first segment.
  • the first segment and the second segment, and optionally, an additional segment, are then coupled to form the cylinder.
  • a knob is then attached to an end of the cervical spine support.
  • the length of the cervical spine support is 20 to 28 inches. Additionally, the cervical spine support is cylindrical and has a diameter of 3 to 6 inches. The cervical spine support is then inserted into a hollow compartment in the pillow.
  • the aforementioned pillow, adjustable cervical spine support, and pillow case system solves problems associated with current technologies relating to alignment of the cervical spine.
  • the above-described system enables user-specific customization options that can account for the wide variety of user comfort preferences.
  • the system provides for additional features that take into account more than pillow firmness and texture.
  • the system solves the problem of "hammocking" by including a pillow case designed to stretch to dimensions of the pillow head well.
  • the term "or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from the context, the phrase “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, the phrase “X employs A or B” is satisfied by any of the following instances: X employs A; X employs B; or X employs both A and B.
  • the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from the context to be directed to a singular form.
  • the term “exemplary” is intended to mean serving as an illustration or example of something, and is not intended to indicate a preference.
  • the present disclosure relates to a cushion and more particularly to a pillow providing cervical alignment by way of an adjustable cervical spine support structure that is positioned along a major axis of the pillow, and that can be rotated around the major axis.
  • the cervical spine support may also be fixed and not adjustable.
  • the cervical spine support can comprise different segments having different properties designed to help a user sleep.
  • the pillow also features a "head well," that is, a depression in the surface of the pillow designed to accommodate a user's head.
  • the pillow disclosed herein is further differentiated by its integration into a dimensionally correct pillow geometry and a platform that is specific to a back sleeper and a side sleeper.
  • the present disclosure also relates to a pillow case in which the pillow and cervical spine support can be disposed therein made of a 4-way stretch material and a non-stretch material.
  • the term "4-way stretch material” means a material that will stretch both crosswise and lengthwise from a rest position when pressure is applied (e.g., pressure from a human head resting on the material) and will revert to a rest position in the absence of pressure.
  • the pillow case may be used with a pillow including a head well such that the central region of the pillow case is positioned next to the head well.
  • the central region stretches to come into contact with the head well, thus preventing "hammocking" of the pillow case. This enables a user of the pillow case to enjoy the therapeutic benefits of a pillow with a head well while retaining the hygienic, tactile, and aesthetic benefits of a traditional pillow case.
  • FIG. 1 shows an example adjustable pillow 100 with an adjustment knob 102 disposed along a major axis 104 of the pillow 100.
  • the adjustment knob 102 is coupled to an adjustable cervical spine support 106 (not shown).
  • the adjustment knob 102 can be used to adjust a firmness of at least a portion of the pillow 100 in order to aid in alignment of a user's cervical spine.
  • the adjustment knob can comprise a soft yet stiff material, such as a foam or rubber material.
  • the adjustment knob 102 can include a protruding center portion that can be grasped by a user in order to twist the knob 102 and thereby adjust the adjustable cervical spine support 106.
  • the adjustable pillow 100 is designed to account for variabilities in end-user physiology, sleep position preference, mattress firmness, and personal comfort preferences.

  • a second adjustment knob may be present on the opposite side of the pillow 100 and is also coupled to the adjustable cervical spine support 106.
  • a universal joint armature 212 runs along the major axis 104 of the adjustable cervical spine support 106 to allow for adjustability while providing flexibility on a variety of mattress densities.
  • a coupling that allows rotation of the cervical spine support 106 about the major axis 104 connects the universal joint armature 212 to the adjustment knob 102.
  • the coupling may be attached to the pillow 100 and provides support to the universal joint armature 212 while allowing the cervical spine support 106 to be rotated.
  • the coupling can be rigid and fixed to the pillow 100 such that the coupling does not rotate, while the universal joint armature 212 protrudes through an opening in the coupling.
  • the adjustment knob 102 can be attached to the portion of the universal joint armature 212 that protrudes through the opening in the fixed coupling, thereby allowing the cervical spine support 106 to be rotated by way of the adjustment 102.
  • the multi-density segments 204, 206, 208 are also of varying hardness.
  • a first section differs by at least 10% in hardness from a second segment, and the second segment differs by at least 10% from a third segment.
  • the recited differences in hardness may be 10% to 1000%, such as 20% to 500%, or 100% to 300%.
  • Hardness or firmness may be measured by Indentation Load Deflection (ILD) (also known as Indentation Force Deflection, or IFD) which is determined by mechanical performance testing.
  • ILD Indentation Load Deflection
  • the ILD test a material sample measuring 15" by 15" by 4" is used and the force in pounds that it takes a 50 square inch circular indenter to compress the material 1 inch (25 percent of its thickness) is recorded. For example, if the sample requires 36 lbs. of pressure to indent it 1 inch, its ILD is 36.
  • the ILD of the segments of material 204, 206, 208 may be 8 to 100, for example, 12 to 70, or 20 to 60.
