Carry-on passenger seat

1. A seat system, comprising:

a support pedestal adapted to be installed within an aircraft, the support pedestal including a fixed base, a post configured to move vertically relative to the base, and an elongate member atop the post configured to rotate horizontally relative to the post; and

a carry-on passenger seat adapted to mount upon the support pedestal, the carry-on passenger seat including a seatback pivotably connected to a seat bottom such that the seatback is configured to fold against the seat bottom, and an elongate slot formed in an underside of the seat bottom, the elongate member of the support pedestal adapted to be received through the elongate slot and rotate relative thereto to prevent the seat bottom from being pulled apart from the support pedestal;

wherein a portion of the seat bottom is captured between the base and the elongate member when the elongate member is in a rotated position within the seat bottom and the post is retracted into the base.

2. The seat system of claim 1 , wherein the base directly contacts the underside of the seat bottom and is contoured complementary to a contour of the underside of the seat bottom.

3. The seat system of claim 1 , wherein the base surrounds the post and the post is configured to rise vertically from the base and lower vertically into the base.

4. The seat system of claim 1 , wherein the carry-on passenger seat is attached to the support pedestal by first vertically raising the post from the base, secondly inserting the elongate member through the elongate slot, thirdly rotating the elongate member horizontally relative to the post, and lastly vertically lowering the post into the base.

5. The seat system of claim 4 , wherein the elongate member is configured to rotate 90 degrees relative to the post.

6. The seat system of claim 1 , wherein the carry-on passenger seat further comprises a headrest pivotably attached to the seatback such that the headrest is configured to fold against the seatback.

7. The seat system of claim 6 , wherein the seatback defines a recess in at least one of a frontside and a backside thereof, the recess adapted to receive the headrest when the headrest is in a stowed position folded against the seatback.

8. The seat system of claim 6 , further comprising a handle located near a pivotal attachment point of the headrest and the seatback, the handle accessible for use when the headrest is folded against the seatback.

9. The seat system of claim 1 , wherein the seat bottom is hollow so as to receive the elongate member of the support pedestal therein.
