Definitions

  • the present invention relates to support cushions including a mixed filling.
  • the present invention relates to support cushions, such as pillows, that make use of a filling comprised of a plurality of fibers and a plurality of flexible foam fragments to provide comfort and support to the body of a user, or a portion thereof, resting on the support cushion.
  • the effectiveness and desirability of the support cushion is partly a function of how well the support cushion supports the body of a user and partly a function of how well the support cushion conforms to the body of a user and provides a feeling of softness.
  • many users find support cushions that are filled with polyester fibers to be particularly desirable as such support cushions significantly deform and provide a feeling of softness when the body of a user, or a portion thereof, is placed on the support cushion. That deformation and feeling of softness, however, is often accompanied by a lack of support that, in turn, leaves many users looking for alternatives to traditional polyester fiber-filled support cushions.
  • support cushions comprised of temperature-sensitive flexible foam.
  • support cushions comprised of temperature-sensitive visco-elastic foam are often desirable as such support cushions are able to change shape and conform to the body of a user based, at least in part, upon the temperature of the supported body part.
  • conformance while providing an increased amount of support, occasionally causes some users to find visco-elastic support cushions to be overly hard, and thus, undesirable for use as a pillow.
  • the present invention relates support cushions including a mixed filling.
  • the present invention relates to support cushions, such as pillows, that make use of a filling comprised of a plurality of fibers and a plurality of flexible foam fragments to provide comfort and support to the body of a user, or a portion thereof, resting on the support cushion.
  • the support cushions of the present invention allow a user to obtain the feeling of softness associated with a support cushion that includes a plurality of flexible fibers, but without the reduction in support that may be found in such fiber-filled support cushions.
  • a support cushion in the form a pillow that includes a filling comprised of a plurality of fibers and a first flexible foam in the form of a plurality of flexible foam fragments.
  • the pillow also includes a sleeve comprised of a second flexible foam.
  • the sleeve includes a first side and a second side opposite the first side that collectively encapsulate the filling.
  • Both the first flexible foam and the second flexible foam are generally comprised of flexible foam that is capable of suitably distributing the pressure from a user's body or portion thereof across the support cushion.
  • the flexible foam is a visco-elastic foam that has a desired density and hardness, and that allows pressure to be distributed uniformly across the support cushion.
  • both the first flexible foam included in the filling and the second flexible foam included in the sleeve are comprised of a visco-elastic foam.
  • the visco-elastic foam comprising the sleeve can have a density less than that of the visco-elastic foam comprising the plurality of flexible foam fragments included in the filling, such that the visco-elastic foam comprising the sleeve provides a softer surface on which to rest, while the visco-elastic foam comprising the plurality of flexible foam fragments provides a desired amount of support.
  • the plurality of flexible foam fragments comprising the first flexible foam can also be configured to improve the comfort and support provided by the support cushion.
  • the plurality of flexible foam fragments are comprised of a first portion of flexible foam fragments and a second portion of flexible foam fragments, where the densities of the first and second portion of flexible foam fragments are not the same.
  • the first portion of flexible foam fragments can have a density that is less than the density of the second portion of flexible foam fragments, such that the first portion of flexible foam fragments is configured to provide a soft surface on which to rest the body of a user, while the second portion of flexible foam fragments is configured to provide support to the body of a user.
  • the plurality of fibers included in an exemplary support cushion can be comprised of natural fibers, synthetic fibers, or combinations thereof.
  • the plurality of fibers include only synthetic fibers, such as, in some embodiments, polyester fibers that are commonly used to fill pillows. Regardless of the types of fibers included in an exemplary support cushion, however, the plurality of fibers are generally evenly dispersed among the plurality of flexible foam fragments and are included in the filling in an amount sufficient to prevent the flexible foam fragments from clumping together and obstructing the movement of air through the support cushion.
  • the plurality of polyester fibers comprise about 50% of the volume of the filling, with the remaining 50% of the volume of the filling being comprised of the plurality of flexible foam fragments (e.g., about 25% of the first portion of flexible foam fragments and about 25% of the second portion of flexible foam fragments).
  • the support cushion further includes a liner that surrounds the sleeve.
  • the liner is comprised of a netting that includes an amount of phase change material, such that the body of a user, or a portion thereof, resting on the pillow is provided with a cooling sensation.
  • the liner can also incorporate one or more flame-retardant materials, such that a flame-retardant barrier surrounds the sleeve and filling of the support cushion.
  • the support cushion can, in certain embodiments, also include an outer cover that surrounds and protects the liner.
  • an outer cover is typically comprised of a textile having a sufficient amount of durability, but that also has a sufficient amount of “breathability” to allow air and heat to travel through the outer cover, and allow the phase change material, if included, in the liner to still provide a cooling effect to a user resting on the pillow.
  • the outer cover is comprised of one-hundred percent cotton.
  • FIG. 1 is a perspective view of an exemplary support cushion, in the form of a pillow, made in accordance with the present invention and with a portion of the support cushion removed to show the filling and the sleeve of the support cushion;
  • FIG. 2 is a partial cross-sectional view of the exemplary support cushion of FIG. 1 taken along line 2 - 2 of FIG. 1 ;
  • FIG. 3 is a perspective view of another exemplary support cushion, in the form of a pillow, made in accordance with the present invention and with a portion of the support cushion removed to show the filling and the sleeve of the support cushion;
  • FIG. 4 is a partial cross-sectional view of the exemplary support cushion of FIG. 3 taken along line 4 - 4 of FIG. 3 ;
  • FIG. 5 is a cross-sectional view of exemplary support cushions for use in a chair and made in accordance with the present invention.

  • the present invention relates to support cushions, such as pillows, that make use of a filling comprised of a plurality of fibers and a plurality of flexible foam fragments to provide comfort and support to the body of a user, or a portion thereof, resting on the support cushion.
  • the support cushions of the present invention allow a user to obtain the feeling of softness associated with a support cushion that includes a plurality of flexible fibers, but without the reduction in support that may be found in such fiber-filled support cushions.
  • a support cushion is provided in the form a pillow 10 that includes a loose filling 20 comprised of a plurality of fibers 26 and a first flexible foam.
  • the first flexible foam is comprised of a first portion of flexible foam fragments 22 and a second portion of flexible foam fragments 24 .
  • the pillow 10 also includes a sleeve 30 that is comprised of a second flexible and that has a first side 32 and a second side 34 opposite the first side 32 .
  • the first portion of flexible foam fragments 22 , the second portion of flexible foam fragments 24 , and the sleeve 30 are each generally comprised of flexible foam that is capable of suitably distributing the pressure from a user's body or portion thereof across the pillow 10 .
  • Such flexible foams include, but are not limited to, latex foam, reticulated or non-reticulated visco-elastic foam (sometimes referred to as memory foam or low-resilience foam), reticulated or non-reticulated non-visco-elastic foam, polyurethane high-resilience foam, expanded polymer foams (e.g., expanded ethylene vinyl acetate, polypropylene, polystyrene, or polyethylene), and the like.
