Aircraft passenger seat and seat swivel assembly
First Claim
1. An aircraft passenger seat swivel assembly for an aircraft seating unit, comprising:
- (a) first and second transversely spaced-apart base rails, wherein a top surface of the first base rail and a top surface of the second base rail are horizontally aligned and define a horizontal plane therebetween;
(b) a swivel assembly mounted between the first and second base rails, the swivel assembly comprising a static swivel plate in which is mounted a rotatable swivel ring, the swivel plate having integrally formed first and second pairs of connecting members extending outwardly in opposite directions therefrom, the first pair of connecting members mounted against an underside of the first base rail and the second pair of connecting members mounted against an underside of the second base rail such that no portion of the swivel assembly extends above the horizontal plane, and the second pair of connecting members having a longer length than the first pair of connecting members such that the static swivel plate is positioned closer to the first base rail than to the second base rail; and
(c) a plurality of vertically oriented bushings attached to the swivel ring and extending above the horizontal plane.

Abstract
An aircraft passenger seat swivel assembly for an aircraft seating unit that includes a pair of transversely spaced-apart base rails, each including fore and aft fittings for connecting the base rails to an aircraft deck. The base rails define a transversely-extending horizontal plane extending between the pair of base rails. A swivel assembly is mounted between the pair of base rails in the laterally-extending horizontal plane. The swivel assembly provides a low profile seat with a spar that forms a part of the swivel assembly and transfers loads from the seat efficiently to the aircraft deck. A slide assembly enables the seat occupant to slide the seat fore-and-aft and side-to-side independent of the rotation of the seat on the swivel.
