A hollow support structure has a first portion that extends within the injection cavity and includes a dispensing feature. A second portion of the support includes a securing feature for engaging an attachment structure. A foam substrate is disposed within the injection cavity. The foam substrate is delivered to the injection cavity within the support structure and through the dispensing feature. ## Claims ### Claim 1 A vehicle headrest comprising: a cover stock shell enclosing an injection cavity; a hollow support including: a first portion extending within the injection cavity and having a dispensing feature; and a second portion having a securing feature for engaging an attachment structure; and a foam substrate disposed within the injection cavity, wherein the foam substrate is delivered to the injection cavity within the hollow support and through the dispensing feature. ### Claim 2 (depends on 1) The vehicle headrest of claim 1, wherein the cover stock shell includes a fabric material that has at least one permeable seam, and wherein the foam substrate defines a predetermined shape of the headrest. ### Claim 3 (depends on 1) The vehicle headrest of claim 1, wherein the attachment structure includes an upper seatback, and wherein the securing feature includes a plurality of notches spaced along the longitudinal extent of the support post for adjusting the height of the headrest relative to the upper seatback. ### Claim 4 (depends on 1) The vehicle headrest of claim 1, further comprising: a tubular channel extending within the hollow support from a distal end of the hollow support to the dispensing aperture, wherein the foam substrate is delivered to the injection cavity via the tubular channel. ### Claim 5 (depends on 1) The vehicle headrest of claim 1, wherein the first portion of the hollow support includes a U-shape and the second portion of the hollow support includes at least two posts extending from the headrest. ### Claim 6 (depends on 5) The vehicle headrest of claim 5, wherein the dispensing feature includes a plurality of apertures that extend to a hollow portion of the hollow support, and wherein the foam substrate is discharged from the hollow portion via the plurality of apertures. ### Claim 7 (depends on 1) The vehicle headrest of claim 1, wherein the cover stock shell includes at least one permeable seam that is configured to exhaust air from the injection cavity when the foam substrate is delivered to the injection cavity. ### Claim 8 A vehicle headrest comprising: a body portion enclosing a cavity and having a post hole; a hollow support post extending through the post hole and having a first portion within the cavity and a second portion for engaging an attachment structure; and a foam substrate injected into the cavity via the support post to occupy the injection cavity in a predetermined shape. ### Claim 9 (depends on 8) The vehicle headrest of claim 8, further comprising: a securing feature on the second portion of the support post for adjustably engaging the body portion with the attachment structure. ### Claim 10 (depends on 9) The vehicle headrest of claim 9, wherein the attachment structure includes a seatback, and wherein the securing feature is configured to adjust the longitudinal height of the body portion relative to the seatback. ### Claim 11 (depends on 8) The vehicle headrest of claim 8, further comprising: a hollow portion extending within the support post from the first portion within the cavity to a distal end of the support post proximate the second portion. ### Claim 12 (depends on 8) The vehicle headrest of claim 8, further comprising: a plurality of dispensing apertures on the first portion of support post, wherein the foam substrate is delivered to the injection cavity through the plurality of dispensing apertures. ### Claim 13 (depends on 8) The vehicle headrest of claim 8, wherein the first portion of the support post includes a U-shaped portion, and wherein the second portion of the support post includes a pair of rods extending from the cavity. ### Claim 14 (depends on 13) The vehicle headrest of claim 13, wherein the U-shaped portion of the support post includes a plurality of dispensing apertures, and wherein a tubular channel extends from the plurality of dispensing apertures to a distal end of the pair of rods to deliver the foam substrate to the cavity. ### Claim 15 A method for forming a headrest comprising: providing a cover stock shell that encloses a cavity and includes a post hole; inserting a hollow support through the post hole and into the cavity, defining a first portion having a dispensing aperture within the cavity and a second portion for engaging an attachment structure and having an injection aperture; and injecting a foam substrate into the cavity via the support to form a body portion. ### Claim 16 (depends on 15) The headrest of claim 15, wherein the support includes a hollow portion extending from the dispensing aperture to the injection aperture, and wherein the foam substrate is delivered to the cavity through the hollow portion of the support. ### Claim 17 (depends on 15) The headrest of claim 15, wherein the cover stock shell includes a leather material that has at least one permeable seam, and wherein the permeable seam is configured to exhaust air from the cavity when the foam substrate is injected into the cavity. ### Claim 18 (depends on 15) The headrest of claim 15, wherein the injection aperture is disposed on a distal end of the second portion of the support, and wherein the foam substrate enters the support through the injection aperture and exits the support through the dispensing aperture. ### Claim 19 (depends on 15) The headrest of claim 15, further comprising: forming a predetermined shape of the body portion with a first mold piece substantially enclosing a head support surface of the body portion and a second mold piece substantially enclosing a rear surface of the body portion. ### Claim 20 (depends on 19) The headrest of claim 19, further comprising removing the second mold piece and removing the body portion from the first mold piece.
