Abstract: The Seat Base Motion Controller provides automated control of seat motion for seat systems employed in providing combined visual and motion experience for patrons in amusement rides and the like. Occupant safety features are integrated within the seat motion control system and centralized control of multiple motion bases is accomplished. Motion control of the seat bases is responsive to a position signal input coordinated with a visual presentation viewed by the patrons. Self contained power systems for the actuation means of the seat base allows sizing of an entertainment threater to accommodate anticipated audiences. Independent control and operation of each motion base precludes the need for shutting down the entire theater if a fault exists in one motion base or the safety systems on that motion base are activated.

Abstract: A track for vehicles which is particularly adapted for amusement park rides having a plurality of banked curves. The track comprises a pair of track rails connected to a lower backbone pipe. In curved sections, the plane of the track rails extends at varying banked angles around the course line of the track. In such sections, the distances between the plane of the track rails and the backbone pipe varies in direct relationship to the bank angle of the curve. The distance between the plane of the track rails and the course line remains constant. The plane of the backbone pipe also remains parallel to the plane of the course line. The course line is preferably disposed a substantial distance above the plane of the track rails.
