Abstract

A stowable seat is provided. The stowable seat may comprise a housing and a first track coupled to the housing. A backrest may be slidably coupled to the first track. A seat pan may be rotatable relative to the backrest. A second track may be in operable communication with the seat pan. An angle between the seat pan and the second track may increase as the seat pan translates away from the housing.

First claim

What is claimed is:

1. A stowable seat, comprising:
a housing;
a first track coupled to the housing;
a backrest in operable communication with the first track;
a seat pan rotatable relative to the housing;
a second track in operable communication with the seat pan, wherein a first angle between the seat pan and the second track increases as the seat pan translates away from the housing,
a plurality of apertures located along the second track; and
a pin coupled to the seat pan, wherein the pin being located within a first aperture of the plurality of apertures restricts translation of the seat pan along the second track.

2. The stowable seat of claim 1 , further comprising:
a footrest pivotably coupled to the seat pan; and
a cushion slidably coupled to the footrest.

3. The stowable seat of claim 1 , wherein translation of the backrest along the first track causes the seat pan to translate along the second track.

4. The stowable seat of claim 1 , wherein a second angle of the backrest relative to vertical is least 40 degrees when the stowable seat is in a fully reclined position.

5. The stowable seat of claim 1 , further comprising a crossbar disposed within the housing, wherein the crossbar limits rotation of the second track.

6. The stowable seat of claim 1 , further comprising a damper coupled to the backrest.

7. The stowable seat of claim 1 , further comprising a lever coupled to the seat pan, wherein the lever is in operable communication with the pin.

8. The stowable seat of claim 1 , wherein pivoting the seat pan away from the backrest translates the backrest along the first track.

9. The stowable seat of claim 1 , wherein increasing a second angle formed by the backrest and the first track increases the first angle formed by the seat pan and the second track.

10. A seat for an aircraft, comprising:
a backrest;
a seat pan rotatable relative to the backrest;
a track in operable communication with the seat pan, wherein a first angle formed by the seat pan and the track changes as the seat pan translates along the track;
a plurality of apertures located along the track; and
a pin coupled to the seat pan, wherein the pin being located within a first aperture of the plurality of apertures restricts translation of the seat pan along the track.

11. The seat of claim 10 , further comprising a lever coupled to the seat pan, wherein the lever is operable communication with the pin.

12. The seat of claim 10 , further comprising a damper coupled to the backrest.

13. The seat of claim 10 , wherein pivoting the seat pan away from the backrest causes a second angle of the backrest relative to vertical to increase.

14. The seat of claim 10 , further comprising a dual wheel coupled to the seat pan, wherein the dual wheel is located within a guide path defined by the track.

15. A method of making a stowable seat, comprising:
slidably coupling a backrest to a first track;
pivotably coupling a seat pan to the backrest;
slidably coupling the seat pan to a second track such that a first angle of the seat pan relative to horizontal changes as the seat pan translates along the second track;
locating a plurality of apertures along the second track; and
configuring the plurality of apertures and a pin coupled to the seat pan to regulate translation of the seat pan along the second track.

16. The method of claim 15 , wherein a second angle formed by the backrest and the first track changes as the seat pan translates along the second track.

17. The method of claim 15 , further comprising coupling a lever to the seat pan, wherein the lever is in operable communication with the pin.
