Abstract

A seat assembly includes a seat cushion, a backrest, and a headrest moveably coupled to a back of the backrest. The headrest is configured to be moved between a stowed position in which the headrest is retained within a portion of the backrest and a deployed position in which the headrest is configured to support a passenger in a forward resting position.

First claim

What is claimed is:

1 . A seat assembly comprising:
a seat cushion; a backrest; and a headrest moveably coupled to a back of the backrest, wherein the headrest is configured to be moved between a stowed position in which the headrest is retained within a portion of the backrest and a deployed position in which the headrest is configured to support a passenger in a forward resting position.

2 . The seat assembly of claim 1 , wherein the headrest in the stowed position is retained within an envelope of the backrest.

3 . The seat assembly of claim 1 , wherein the headrest in the stowed position is flush mounted with the back of the backrest.

4 . The seat assembly of claim 1 , wherein the headrest in the stowed position is retained within a reciprocal retaining chamber formed in the back of the backrest.

5 . The seat assembly of claim 1 , wherein the headrest is moveably coupled to an upper portion of the back of the backrest.

6 . The seat assembly of claim 1 , wherein the headrest comprises a head support beam that spans between opposed lateral pivot beams.

7 . The seat assembly of claim 6 , wherein the head support beam extends between upper ends of the lateral pivot beams, and wherein lower ends of the lateral pivot beams are pivotally coupled to the back of the backrest.

8 . The seat assembly of claim 1 , further comprising a moveable latch that securely retains the headrest in the stowed position.

9 . The seat assembly of claim 1 , further comprising an electronic device secured within the back of the backrest.

10 . The seat assembly of claim 9 , wherein the headrest in the stowed position extends around one or more portions of an electronic device.

11 . The seat assembly of claim 1 , further comprising a tray table moveably coupled to the back of the backrest.

12 . The seat assembly of claim 11 , wherein the tray table is positioned below the headrest.

13 . The seat assembly of claim 1 , wherein the headrest comprises a padded insert.

14 . The seat assembly of claim 13 , wherein the padded insert is removably secured to a retaining bracket.

15 . The seat assembly of claim 13 , further comprising an antimacassar removably secured to the padded insert.

16 . The seat assembly of claim 13 , wherein the padded insert is configured to be radially shifted relative to a head support beam of the headrest.

17 . A method of forming a seat assembly, the method comprising:
moveably coupling the headrest to a back of a backrest of the seat assembly, wherein the moveably coupling allows the headrest to be moved between a stowed position in which the headrest is retained within a portion of the backrest and a deployed position in which the headrest is configured to support a passenger in a forward resting position.

18 . The method of claim 17 , further comprising retaining the headrest in the stowed position within an envelope of the backrest.

19 . A vehicle comprising:
an interior cabin; and a seat assembly within the interior cabin, wherein the seat assembly comprises:
a seat cushion;
a backrest;
a headrest moveably coupled to a back of the backrest, wherein the headrest is configured to be moved between a stowed position in which the headrest is retained within a portion of the backrest and a deployed position in which the headrest is configured to support a passenger in a forward resting position, wherein the headrest in the stowed position is retained within an envelope of the backrest, wherein the headrest in the stowed position is flush mounted with the back of the backrest, wherein the headrest in the stowed position is retained within a reciprocal retaining chamber formed in the back of the backrest, wherein the headrest is moveably coupled to an upper portion of the back of the backrest, wherein the headrest comprises a head support beam that spans between opposed lateral pivot beams, wherein the head support beam extends between upper ends of the lateral pivot beams, and wherein lower ends of the lateral pivot beams are pivotally coupled to the back of the backrest;
a moveable latch that securely retains the headrest in the stowed position;
an electronic device secured within the back of the backrest, wherein the headrest in the stowed position extends around one or more portions of an electronic device; and
a tray table moveably coupled to the back of the backrest, wherein the tray table is positioned below the headrest and the electronic device.

20 . The vehicle of claim 19 , wherein the headrest further comprises:
a padded insert removably secured to a retaining bracket of the head support beam, wherein the padded insert is configured to be radially shifted relative to a head support beam of the headrest; and an antimacassar removably secured to the padded insert.
