Plinth-mounted seat assembly and mounting sub-assemblies

1. A seat mounting assembly, comprising:

a swingarm adapted to mount transverse to spaced-apart floor tracks;

a plinth having a seat mounted thereon mounted on the swingarm such that the swingarm is configured to deflect in a direction away from the plinth in response to floor deformation; and

first and second clevis sub-assemblies, spaced apart from the swingarm and from each other, adapted to attach the plinth to the spaced-apart floor tracks, each of the first and second clevis sub-assemblies received within a corresponding opening through the plinth that narrows in a direction of a rear of the plinth such that each clevis sub-assembly slides into locking engagement with the plinth to prevent vertical movement therebetween in an engaged position.

2. The seat mounting assembly according to claim 1 , wherein the swingarm is adapted to attach at opposing ends thereof to spaced apart floor tracks and attach to the plinth such that in operation the swingarm is configured to deflect and move away from the plinth in response to floor deformation without deforming the plinth.

3. The seat mounting assembly according to claim 1 , wherein the swingarm engages the plinth at a forward end of the plinth and the clevis sub-assemblies engage the plinth at rear corners of the plinth.

4. The seat mounting assembly according to claim 1 , wherein each of the first and second clevis sub-assemblies comprise a clevis pivotally connected to a track fitting.

5. The seat mounting assembly according to claim 1 , wherein the plinth is mounted on the swingarm centrally along the length of the swingarm such that each end of the swingarm is able to deflect downward away from the plinth.

6. The seat mounting assembly according to claim 1 , wherein the plinth slides into locking engagement with the swingarm to allow vertical movement together and prevent vertical movement therebetween in an engaged position.

7. The seat mounting assembly according to claim 1 , wherein the swingarm is pivotally connected at opposing ends thereof to track fittings.

8. The seat mounting assembly according to claim 1 , further comprising a privacy shell mounted on the plinth.

9. The seat mounting assembly according to claim 8 , wherein attachment points for mounting the seat and the privacy shell to the plinth are concealed from view from above.

10. An assembly adapted to mount a suite-style seat supported on a plinth to spaced-apart floor tracks to isolate the plinth from floor deformation, the assembly comprising:

a swingarm adapted to attach to spaced-apart floor tracks and engaging the plinth such that the swingarm deflects away from the plinth in response to floor deformation; and

clevis sub-assemblies spaced apart from the swingarm and from each other adapted to attach the plinth to spaced-apart floor tracks, each of the clevis sub-assemblies comprising a clevis pivotally connected to a track fitting, wherein each clevis sub-assembly is received within a corresponding opening through the plinth that narrows in a direction of a rear of the plinth such that each clevis sub-assembly slides into locking engagement with the plinth to prevent vertical movement therebetween in an engaged position;

wherein the swingarm engages the plinth at a forward end of the plinth and the clevis sub-assemblies engage the plinth at rear corners of the plinth.

11. The assembly according to claim 10 , wherein the swingarm is adapted to attach at opposing ends thereof to spaced apart floor tracks and to the plinth such that in operation the swingarm is configured to deflect and move away from the plinth in response to floor deformation without deforming the plinth.

12. The assembly according to claim 10 , wherein the swingarm is adapted to mount transverse to spaced-apart floor tracks.

13. The assembly according to claim 10 , wherein the plinth is mounted on the swingarm centrally along the length of the swingarm such that each end of the swingarm is able to deflect downward away from the plinth, and wherein the plinth slides into locking engagement with the swingarm to allow vertical movement together and prevent vertical movement therebetween in an engaged position.

14. The assembly according to claim 10 , wherein the swingarm is pivotally connected at opposing ends thereof to track fittings.

15. The assembly according to claim 10 , wherein the suite-style seat includes at least a passenger seat and a privacy shell attached to the plinth.

16. The assembly according to claim 15 , wherein attachment points for mounting the seat and the privacy shell to the plinth are concealed from view from above.
