a plurality of pitch clevises including a first set of pitch clevises coupled on a top surface of a first of the set of base rails and a second set of pitch clevises coupled on a top surface of a second of the set of base rails, each of the plurality of pitch clevises including a hole disposed on a top surface of the plurality of pitch clevises, wherein the plurality of pitch clevises are configured to provide a mechanical strength and stability to support a passenger seat in absence of spars;
a swivel outer plate aligned in parallel relative to the floor, the swivel outer plate comprising:
a plurality of slots located on corners of the swivel outer plate; and
a plurality of spacers disposed within the plurality of slots, wherein the swivel outer plate is coupled to the plurality of pitch clevises through the plurality of the spacers and the hole of each of the plurality of pitch clevises.

2. The adjustable swiveling passenger seat assembly of claim 1 , wherein the plurality of spacers each include a spacer protrusion configured to fit within the plurality of slots; wherein the plurality of spacers each include an aperture configured to receive a pin coupling the swivel outer plate and the pitch clevis; wherein a width between the set of base rails is adjustable by rotating the plurality of spacers 180 degrees to change a location of the aperture.

3. The adjustable swiveling passenger seat assembly of claim 1 , further comprising:
a plurality of clevis pins configured to couple the plurality of pitch clevises with each of the set of base rails, wherein the plurality of clevis pins is perpendicularly aligned relative to each of the set of base rails and aligned in parallel relative to the floor.

4. The adjustable swiveling passenger seat assembly of claim 1 , wherein the plurality of pitch clevises is formed from at least one of carbon steel, steel iron nickel alloy, stainless steel, tungsten, tungsten carbide, titanium, titanium aluminide, chromium, iron, aluminum, composite materials, carbon fibers, and polymers.

5. The adjustable swiveling passenger seat assembly of claim 1 , wherein a shape of the plurality of pitch clevises includes at least one of U-shape, V-shape, C-shape, and mushroom shape.

6. The adjustable swiveling passenger seat assembly of claim 1 , wherein the swivel outer plate is configured to support the passenger seat that rotates 360 degrees.

7. The adjustable swiveling passenger seat assembly of claim 1 , wherein the adjustable swiveling passenger seat assembly is configured to be used in vehicles.

8. The adjustable swiveling passenger seat assembly of claim 7 , wherein the vehicles that the adjustable swiveling passenger seat assembly is used include one of motor vehicles, railed vehicle, watercraft, amphibious vehicles, aircraft, or spacecraft.

9. An adjustable swiveling passenger seat, comprising:
a set of base rails, wherein the set of base rails are aligned in parallel to each other and are in parallel with a direction of travel;
a plurality of floor fittings coupling the set of base rails with a set of seat tracks of a floor;
a plurality of pitch clevises including a first set of pitch clevises coupled on a top surface of a first of the set of base rails and a second set of pitch clevises coupled on a top surface of a second of the set of base rails, each of the plurality of pitch clevises including a hole disposed on a top surface of the plurality of pitch clevises, wherein the plurality of pitch clevises are configured to provide a mechanical strength and stability in absence of spars;
a swivel outer plate aligned in parallel relative to the floor, the swivel outer plate comprising:
a plurality of slots located on corners of the swivel plate;
a plurality of spacers disposed within the plurality of slots, wherein the swivel outer plate is coupled to the plurality of pitch clevises through the plurality of the spacers and the hole of each of the plurality of pitch clevises; and

a swivel seat mounted on the swivel outer plate.

10. The adjustable swiveling passenger seat of claim 9 , wherein the plurality of spacers each include a spacer protrusion configured to fit within the plurality of slots; wherein the plurality of spacers each include an aperture configured to receive a pin coupling the swivel outer plate and the pitch clevis; wherein a width between the set of base rails is adjustable by rotating the plurality of spacers 180 degrees to change a location of the aperture.

11. The adjustable swiveling passenger seat of claim 9 , further comprising:
a plurality of clevis pins configured to couple the plurality of pitch clevises with each of the set of base rails, wherein the plurality of clevises pins is perpendicularly aligned relative to each of the set of base rails and aligned in parallel relative to the floor.

12. The adjustable swiveling passenger seat of claim 9 , wherein the plurality of pitch clevises is formed from at least one of carbon steel, steel iron nickel alloy, stainless steel, tungsten, tungsten carbide, titanium, titanium aluminide, chromium, iron, aluminum, composite materials, carbon fibers, and polymers.

13. The adjustable swiveling passenger seat of claim 9 , wherein a shape of the plurality of pitch clevises includes at least one of U-shape, V-shape, C-shape, and mushroom shape.

14. The adjustable swiveling passenger seat of claim 9 , wherein the floor includes at least one of main deck floor, overhead compartment floor, and cargo compartment floor.

15. The adjustable swiveling passenger seat of claim 9 , wherein the swivel seat is configured to rotate 360 degrees at a yaw axis.

16. An adjustable swiveling passenger seat assembly, comprising:
a set of base rails aligned in parallel to each other and are in parallel with a direction of travel;
a plurality of floor fittings configured to couple each of the set of base rails with a set of seat tracks of a floor;
a plurality of pitch clevises including a first set of pitch clevises coupled on a top surface of a first of the set of base rails and a second set of pitch clevises coupled on a top surface of a second of the set of base rails, each of the plurality of pitch clevises including a hole disposed on a top surface of the plurality of pitch clevises, wherein the plurality of pitch clevises are configured to provide mechanical strength and stability in absence of spars;
