Adjustable cantilever vehicle seat mounting assemblies and seat systems including the same

An aircraft seat system comprising:

• a passenger seat, and
• a mounting assembly connected to the passenger seat to allow positional adjustments thereof, wherein the mounting assembly comprises:
• (i) a mounting bracket adapted to being rigidly attached to laterally adjacent fuselage structure of an aircraft;
• (ii) a pivot bracket operatively connected to the mounting bracket for reciprocal vertical movements relative to the mounting bracket between raised and lowered positions thereof;
• (iii) a tubular support member operatively associated with the pivot bracket and pivotally movable about a substantially vertical central axis of the pivot bracket;
• (iv) a cantilevered support base arm having a proximal end fixed to the tubular support member to allow for pivotal movements thereof about the substantially vertical central axis of the pivot bracket and extending outwardly from the tubular support member along a substantially horizontal axis defined thereby;
• (v) an arm member telescopically connected to the cantilevered support base arm to allow reciprocal rectilinear movements relative to the support base arm along the substantially horizontal axis thereof between retracted and extended positions thereof, and
• (vi) a swivel plate connected to and carried by a distal end of the arm member, the swivel plate being operatively connected to the passenger seat to allow swivel movements of the passenger seat about a substantially vertical seat axis parallel to the substantially vertical central axis of the pivot bracket.
