Long rail assembly with triple rail configuration

A long rail assembly for repositioning a seat assembly in a vehicle comprising:

• an inboard lower channel adapted to extend longitudinally along a floor of the vehicle;
• an inboard manual drive assembly configured to be coupled to the seat assembly and slidably coupled to the inboard lower channel;
• an outboard lower channel adapted to extend longitudinally along the floor of the vehicle;
• an outboard manual drive assembly configured to be coupled to the seat assembly and slidably coupled to the outboard lower channel;
• a central lower channel adapted to extend longitudinally along the floor of the vehicle;
• a power drive assembly configured to be coupled to the seat assembly, the power drive assembly comprising:
• a central upper channel slidably coupled to the central lower channel;
• and
• a gearbox coupled to the central upper channel, wherein the power drive assembly power drives the seat assembly along the central lower channel to selectively reposition the seat assembly in the vehicle;
• a rack fixedly coupled to the central lower channel, wherein the rack includes gear teeth extending along the rack in a longitudinal direction;
• a pinion meshingly engaged with the gear teeth;
• a drive shaft operatively coupling the gearbox to the pinion;
