Abstract

A forward concave trapezoidal seating system and methods are presented. Trapezoidal seats comprise a front side smaller than a rear side. The trapezoidal seats are aligned in a forward arc from a straight seat to a most-angled seat. A straight side of the straight seat is configured to substantially align with a center line of an aircraft fuselage. A most-angled side of the most-angled seat is angled inboard relative to the straight side, and the most-angled seat is outboard of the straight seat. A side unit is coupled to the most-angled side and supports the trapezoidal seats.

First claim

The invention claimed is:

1. A forward concave trapezoidal seating system comprising:
a plurality of trapezoidal seats comprising a trapezoidal base, the trapezoidal base comprising a front side smaller than a rear side,
the trapezoidal seats aligned in a forward arc from a straight seat from among the trapezoidal seats to a most-angled seat from among the trapezoidal seats;
wherein the trapezoidal base of the straight seat comprises a straight side of the straight seat in parallel with a center line of an aircraft fuselage;
a most-angled side of the most-angled seat angled inboard relative to the straight side, the most-angled seat outboard of the straight seat; and
a triangular shaped side unit coupled to the most-angled side and suspending the trapezoidal seats in a cantilever manner,
wherein a side of the side unit is angled inboard relative to the straight side and wherein the side unit is outboard of the straight seat.

2. The system of claim 1 , wherein the most-angled seat is aligned at an angle that reduces an effect on a passenger of at least one of: a centrifugal force, a yaw force, and a roll force.

3. The system of claim 1 , wherein the side unit comprises a storage space.

4. The system of claim 1 , wherein the straight side is configured on an aisle.

5. The system of claim 1 , wherein a first row seat in a first row is adjustable to adjust back to recline between two seats in a second row behind the first row.

6. The system of claim 1 , wherein the trapezoidal seats are supported only by the side unit.

7. The system of claim 1 , wherein:
the trapezoidal seats comprise a first most-angled seat on a first side and a second most-angled seat on a second side;
the side unit comprises a first side unit and a second side unit;
the first side unit is coupled to the first most-angled seat;
the second side unit is coupled to the second most-angled seat; and
the trapezoidal seats are supported only by the first side unit and the second side unit.

8. A method for configuring a curved seating arrangement in an aircraft, the method comprising:
aligning a plurality of trapezoidal seats comprising a trapezoidal base, the trapezoidal base comprising a front side smaller than a rear side in a forward arc from a straight seat from among the trapezoidal seats to a most-angled seat from among the trapezoidal seats, wherein the straight seat comprises a straight side of the trapezoidal base;
configuring the straight side of the trapezoidal base of the straight seat in parallel with a center line of an aircraft fuselage;
configuring the most-angled seat outboard of the straight seat;
configuring a most-angled side of the most-angled seat at an angle inboard relative to the straight side;
coupling a triangular shaped side unit to suspend the trapezoidal seats in a cantilever manner; and
configuring the straight side on an aisle.

9. The method of claim 8 , further comprising aligning the most-angled seat at an angle that reduces an effect on a passenger of at least one of: a centrifugal force, a yaw force, and a roll force.

10. The method of claim 8 , further comprising configuring a storage space in the side unit.

11. The method of claim 8 , wherein a first row seat in a first row is adjustable to adjust back to recline between two seats in a second row behind the first row.

12. The method of claim 8 , wherein the trapezoidal seats are supported only by the side unit.

13. A method for configuring aircraft passenger cabin seating, the method comprising:
configuring a plurality of curved seating arcs each comprising a plurality of trapezoidal seats, the trapezoidal seats comprising a trapezoidal base, the trapezoidal base comprising a front side smaller than a rear side;
aligning each of the curved seating arcs in a forward arc from a straight seat from among the trapezoidal seats to a most-angled seat from among the trapezoidal seats, wherein the trapezoidal base of the straight seat comprises a straight side in parallel with a center line of an aircraft fuselage;
positioning the curved seating arcs in an aircraft cabin; and
suspending the trapezoidal seats in a cantilever manner from a triangular shaped side unit,
wherein the trapezoidal seats are aligned and positioned in the aircraft cabin such that none of the trapezoidal seats are angled outboard.

14. The method of claim 13 , further comprising:
configuring the straight side of the straight seat in parallel with the center line of the aircraft fuselage;
configuring the most-angled seat outboard of the straight seat;
configuring a most-angled side of the most-angled seat at an angle inboard relative to the straight side; and
coupling the side unit to the trapezoidal seats to suspend the trapezoidal seats in the cantilever manner.

15. The method of claim 14 , further comprising configuring a storage space in the side unit.

16. The method of claim 14 , further comprising configuring the straight side on an aisle.

17. The method of claim 14 , wherein the trapezoidal seats are suspended only by the side unit.

18. The method of claim 13 , wherein a first row seat in a first row is adjustable to adjust back to recline between two seats in a second row behind the first row.

19. The method of claim 13 , further comprising aligning the most-angled seat at an angle that reduces an effect on a passenger of at least one of: a centrifugal force, a yaw force, and a roll force.

20. The method of claim 8 , wherein a side of the side unit is angled inboard relative to the straight side and wherein the side unit is outboard of the straight seat.

21. The method of claim 14 , wherein a side of the side unit is angled inboard relative to the straight side and wherein the side unit is outboard of the straight seat.

22. The method of claim 13 , wherein the aircraft cabin comprises at least one aisle separating adjacent ones of the plurality of curved seating arcs.
