Abstract

A contoured stowable seat is provided. The contoured stowable seat may comprise a housing, a seat pan, a contoured backrest, and a deployment lever. The contoured stowable seat may be configured to be in a stowed position and a deployed position. In response to the seat pan being in the deployed position, the deployment lever may contact the contoured backrest, causing the contoured backrest to deploy and form into a contoured shape. The contoured stowable seat may also further comprise a tension cord and a headrest. The contoured backrest may also further comprise a cushion located on the outer surface of the contoured backrest.

First claim

What is claimed is:

1. A seat, comprising:
a housing;
a seat pan pivotably coupled to the housing, wherein the seat pan is configured to pivot from a stowed position into a deployed position;
a contoured backrest coupled to the housing, wherein the contoured backrest comprises a frame defining an outer edge of the contoured backrest; and
a deployment lever rotatably coupled to the housing, wherein in response to the seat pan being pivoted into the deployed position the deployment lever is configured to deploy the contoured backrest into a contoured shape, and wherein the frame comprises a flex point configured to bend in a direction away from the housing in response to the contoured backrest being deployed into the contoured shape.

2. The seat of claim 1 , further comprising a tension cord having a first end and a second end, wherein the first end is coupled to the housing and the second end is coupled to the contoured backrest.

3. The seat of claim 2 , wherein, in response to the seat pan pivoting into the deployed position, the tension cord is configured to deploy the contoured backrest into a second contoured shape by imparting tension to a location where the second end is coupled to the contoured backrest.

4. The seat of claim 1 , wherein the seat pan and the contoured backrest are configured to stow at least partially in the housing in response to the seat pan being in the stowed position.

5. The seat of claim 1 , further comprising a contoured pad coupled to an outer surface of the contoured backrest.

6. The seat of claim 1 , wherein the contoured backrest is coupled to the housing via a slidable joint, allowing the contoured backrest to slide relative to the housing in response to the seat pan pivoting into the deployed position.

7. The seat of claim 1 , further comprising a headrest coupled to a top of the housing and an at least one foot coupled to a bottom of the housing.

8. The seat of claim 1 , wherein the contoured backrest comprises a stretch material coupled to an inner surface of the frame.

9. The seat of claim 1 , further comprising a seat restraint coupled to the housing.

10. A method of operating the seat of claim 1 , comprising:
pivoting the seat pan into the deployed position, wherein in response to the seat pan being in the deployed position the deployment lever is configured to deploy the contoured backrest into the contoured shape, causing the flex point to bend in a direction away from the housing; and
pivoting the seat pan into the stowed position, wherein in response to the seat pan being in the stowed position the deployment lever is configured to allow the contoured backrest to form into a relaxed shape.

11. A contoured stowable seat, comprising:
a housing having a top and a bottom;
a seat pan pivotably coupled to the housing at a position between the top and the bottom, wherein the seat pan is configured to pivot from a stowed position into a deployed position;
a contoured backrest comprising a frame and a stretch material, wherein the stretch material is coupled to the frame and the frame defines an axially outer edge of the stretch material, and wherein the frame is coupled to the housing at a first position proximate the top of the housing and at a second position proximate where the seat pan couples to the housing;
a tension cord having a first end and a second end, wherein the first end is coupled to the housing and the second end is coupled to the stretch material of the contoured backrest; and
a deployment lever having a first deployment end and a second deployment end, wherein the first deployment end is coupled to the seat pan at a location proximate the coupling of the seat pan to the housing, and wherein the second deployment end is configured to contact the frame of the contoured backrest in response to the seat pan being in the deployed position, causing the contoured backrest to deploy into a contoured shape.

12. The contoured stowable seat of claim 11 , further comprising a seat restraint coupled to the housing.

13. The contoured stowable seat of claim 11 , wherein in response to the seat pan pivoting into the deployed position, the tension cord is configured to deploy the contoured backrest into a second contoured shape by imparting tension to a location where the second end is coupled to the contoured backrest.

14. The contoured stowable seat of claim 11 , wherein the seat pan and the contoured backrest are configured to stow at least partially in the housing in response to the seat pan being in the stowed position.

15. The contoured stowable seat of claim 11 , further comprising a contoured pad coupled to an axially outer surface of the stretch material of the contoured backrest.

16. The contoured stowable seat of claim 11 , wherein the frame of the contoured backrest is coupled to the housing at the first position via a slidable joint, allowing the contoured backrest to slide relative to the housing in response to the seat pan pivoting into the deployed position.

17. The contoured stowable seat of claim 11 , further comprising a headrest coupled to the top of the housing.

18. The contoured stowable seat of claim 11 , wherein the frame further comprises a flex point configured to bend in a direction away from the housing, in response to the seat pan pivoting into the deployed position.
