Constant center lounge seat

A lounge seat for a vehicle, the lounge seat comprising:

• a seat frame assembly having a front end and a rear end;
• a back frame assembly pivotably coupled to the rear end of the seat frame assembly;
• a track assembly including:
• a plurality of bottom tracks configured to be fixed to the vehicle;
• and
• a plurality of upper tracks, each of the plurality of upper tracks being slidably coupled to a corresponding bottom track of the plurality of bottom tracks;
• a plurality of front couplers coupling the front end of the seat frame assembly to the plurality of upper tracks;
• a plurality of rear couplers coupling the rear end of the seat frame assembly to the plurality of upper tracks;
• a height adjust motor configured to cause movement of the seat frame assembly;
• a recline motor configured to pivot the back frame assembly relative to the seat frame assembly;
• and
• a track motor configured to translate the plurality of upper tracks along the plurality of lower tracks in an X direction;
• wherein, as the lounge seat is reconfigured from a full upright orientation to a full down orientation, (i) the track motor is configured to cause the seat frame assembly to move along the X direction, (ii) the height adjust motor is configured to cause the front end of the seat frame assembly to raise and cause the rear end of the seat frame assembly to lower, and (iii) the recline motor is configured to cause the back frame assembly to pivot downward;
• wherein the lounge seat defines a seat reference point;
• wherein, as the lounge seat is repositioned between the full upright orientation and the full down orientation, the track motor is controlled to translate the plurality of upper tracks along the plurality of lower track such that an X position of the lounge seat is configured to deviate less than 15 mm in the X direction from an initial X position of the seat reference point as the lounge seat is repositioned between the full upright orientation and the full down orientation;
• and
• wherein a difference between the initial X position of the seat reference point associated with the full upright orientation and a final X position of the seat reference point associated with the full down orientation in the X direction is less than 5 mm.

A lounge seat for a vehicle, the lounge seat defining a seat reference point, the lounge seat comprising:

• a seat frame assembly;
• a back frame assembly pivotably coupled to the seat frame assembly;
• a track assembly coupled to the seat frame assembly and configured to facilitate translating the seat frame assembly in a X direction, the track assembly including:
• a plurality of bottom tracks configured to be fixed to the vehicle;
• and
• a plurality of upper tracks, each of the plurality of upper tracks being slidably coupled to a corresponding bottom track of the plurality of bottom tracks;
• and
• a plurality of motors configured to cause movement of the seat frame assembly, the back frame assembly, and the track assembly to adjust the lounge seat between a full upright orientation associated with an initial X position of the seat reference point along the X direction and a full down orientation associated with a final X position of the seat reference point along the X direction, wherein the initial X position and the final X position are substantially the same.
