Abstract
An adjustable seating system for a vehicle, particularly an aircraft, providing means for readily adapting the seating layout in an aircraft cabin to vary passenger density where a plurality of seating units are mounted upon a pair of longitudinal seat rails. Each seating unit incorporates a seat adjustment and locking system comprising a pair of interconnected sprocket wheels arranged to be in driving engagement with a related one of the seat rails so that the seating units can be moved to selected locations without physical separation from the track. Sprocket locking means, when engaged, restrains the seat against horizontal movement and reacts induced fore and aft flight loads obviating the need for separate seat rail engaging restraint means.
