Abstract
Official abstract text for this publication.
A headrest adjusting bracket surrounds posts from the headrest. A screw displaces one side of the bracket to apply a frictional force to the headrest posts. Protrusions on the interior surface of the bracket, proximal to each post, increases the surface area contact between the bracket and the posts when the screw is tightened.
First claim
Opening claim text (preview).
What is claimed is: 1. An aircraft headrest adjusting bracket comprising: a bracket body having a first side and a second side, the bracket body defining at least two headrest post engaging portions and an internal gap separating the first side and the second side, and at least two protrusions disposed on an interior surface defining the internal gap, each proximal to a corresponding headrest post engaging portion; and a tensioning element engaging the first side and the second side, wherein the tensioning element is configured to displace the first side toward the second side to create tension between the bracket body and headrests posts disposed within headrest post engaging portions. 2. The aircraft headrest adjusting bracket of claim 1 , wherein the tensioning element comprises a screw configured to pass through the first side and threadedly engage the second side. 3. The aircraft headrest adjusting bracket of claim 2 , wherein the second side defines two or more aircraft seat connection portions. 4. The aircraft headrest adjusting bracket of claim 3 , wherein the bracket body further comprises at least two protrusions disposed on an interior surface of the first side, each proximal to a corresponding headrest post engaging portion. 5. The aircraft headrest adjusting bracket of claim 3 , wherein the second side has a greater cross-sectional thickness than the first side. 6. The aircraft headrest adjusting bracket of claim 1 , wherein the bracket body comprises Nylon 66. 7. An aircraft seat comprising: a headrest comprising at least two posts configured to engage a seat frame; and an aircraft headrest adjusting bracket disposed on an internal surface of the seat frame, comprising: a bracket body having a first side and a second side, the bracket body defining at least two headrest post engaging portions and an internal gap separating the first side and the second side, and at least two protrusions disposed on an interior surface defining the internal gap, each proximal to a corresponding headrest post engaging portion; and a tensioning element engaging the first side and the second side, wherein the tensioning element is configured to displace the first side toward the second side to create tension between the bracket body and the headrests posts when disposed within headrest post engaging portions. 8. The aircraft seat of claim 7 , wherein the at least two protrusions are disposed on an interior surface of the second side. 9. The aircraft seat of claim 7 , wherein the tensioning element comprises a screw configured to pass through the first side and threadedly engage the second side. 10. The aircraft seat of claim 9 , wherein the second side defines two or more aircraft seat connection portions. 11. The aircraft seat of claim 10 , wherein the bracket body further comprises at least two protrusions disposed on an interior surface of the first side, each proximal to a corresponding headrest post engaging portion. 12. The aircraft seat of claim 10 , wherein the second side has a greater cross-sectional thickness than the first side. 13. The aircraft seat of claim 7 , wherein the bracket body comprises Nylon 66.
