  "abstract": "A bearing including an annular substrate defining a first and a second opposite axial ends; and a plurality of sliding components attached to and extending radially from the annular substrate, each sliding component extending at least partially between the first and second opposite axial ends of the annular substrate. A head restraint assembly including a head restraint having a body and a first and second post extending from the body; a first guide sleeve having a first bearing for receiving the first post; and a second guide sleeve having a second bearing for receiving the second post.",
  "claims": [
    "1. A bearing comprising: a first component having a body defining a first and a second opposite axial ends and a lumen extending between the first and second opposite axial ends, the first component having a plurality of cutouts extending along at least a portion of an axial length thereof; and a plurality of discrete second components each disposed at least partially within one of the cutouts, the second components extending radially from the generally cylindrical body of the first component, wherein at least one of the second components extends along at least 50% and no greater than 100% of the axial length of the first component, wherein at least one of the cutouts, when viewed along the axial length of the lumen, has a T-Shaped cross section, wherein at least one of the second components comprises a laminate structure comprising a substrate and a low friction material, wherein at least one of the second components comprises a complementary engagement component, and wherein the complementary engagement component of the second component adapted to form an interference fit with the cutout and secure the first and second components together.",
    "2. The bearing according to claim 1, wherein the plurality of second components are spaced apart around a circumference of the annular substrate.",
    "3. A head restraint assembly comprising: a head restraint comprising a body and a first and second post extending from the body; a first guide sleeve comprising a first bearing for receiving the first post; and a second guide sleeve comprising a second bearing for receiving the second post, wherein at least one of the first and second guide sleeves comprises a head restraint bearing in accordance with claim 1.",
    "4. The bearing according to claim 1, wherein at least one of the second components comprises a unitary construction.",
    "5. The bearing according to claim 1, wherein the second component is removable from the first component.",
    "6. The bearing according to claim 1, wherein at least one of the second components is visible along at least one axial ends of the first component.",
    "7. The bearing according to claim 1, wherein at least one of the second components has at least one tapered axial end.",
    "8. The bearing according to claim 1, wherein, when viewed along the axial length of the lumen, at least one of the cutouts has a throttled opening.",
    "9. The bearing according to claim 1, wherein an interior surface of the first component is exposed between the cutouts.",
    "10. A head restraint assembly comprising: a head restraint comprising a body and a first and second post extending from the body; a first guide sleeve comprising a first bearing for receiving the first post; and a second guide sleeve comprising a second bearing for receiving the second post, wherein at least one of the first and second guide sleeves comprises a head restraint bearing in accordance with claim 1.",
    "11. A method of forming a bearing comprising: shaping a material to form a generally annular body having cutouts along an interior surface, the cutouts each extending at least partially along an axial length of the generally annular body; and engaging a plurality of discrete sliding components in the cutouts, wherein the sliding components extend radially inward from the interior surface of the generally annular body, wherein at least one of the sliding components extends along at least 50% and no greater that 100% of the axial length of the annular body, wherein at least one of the cutouts, when viewed along the axial length of the annular body, has a T-Shaped cross section, wherein at least one of the sliding components comprises a laminate structure comprising a substrate and a low friction material, wherein at least one of the sliding components comprises a complementary engagement component, and wherein the complementary engagement component of the sliding component is adapted to form an interference fit with the cutout and secure the annular body and the sliding component together.",
    "12. The method according to claim 11, wherein engaging the plurality of sliding components in the cutouts is performed at least partially by molding the sliding components within the cutouts.",
    "13. The method according to claim 11, wherein engaging the plurality of sliding components in the cutouts is performed at least partially by translating each sliding component, translating the generally annular body, or a combination thereof.",
    "14. The method according to claim 11, wherein shaping the material is performed by bending, injection molding, or a combination thereof."

  "description_excerpt": "The present disclosure is directed to a bearing.\n\nBearings provide low friction slip interfaces between components. At a most basic level, a bearing can include a low friction material interfacing between two components which are movable with respect to one another. The bearing can include a material which lowers the coefficient of friction between the two components, thus facilitating easier movement therebetween.\n\nSeat head restraints traditionally include a cushion and two posts. The posts extend into a seatback. A bearing can be disposed between the seatback and the posts to facilitate translation therebetween.\n\nThe industry continues to demand a head restraint bearing capable of providing sufficient rigidity and a suitable low friction slip interface while simultaneously having a cost effective design.\n\nEmbodiments are illustrated by way of example and are not intended to be limited in the accompanying figures.\n\nFIG. 1 includes a top elevation view of a bearing in accordance with an embodiment.\n\nFIG. 2 includes a perspective view of a laminated sliding component in accordance with an embodiment.\n\nFIG. 3 includes a perspective view of a low friction bar in accordance with an embodiment.\n\nFIG. 4 includes a top elevation view of a bearing in accordance with an embodiment.\n\nFIG. 5 includes a cross-sectional perspective view of the bearing of FIG. 4 as seen along line A-A.\n\nFIG. 6 includes an exploded top perspective view of a vehicle seat assembly in accordance with an embodiment.",
