An amusement device has an elongated track along which one or more amusement device seat assemblies adapted to carry the one or more passengers are moveable. Each seat assembly has a seat with a seating surface and a back support with a back support surface. The seat assembly further includes a bar construction attached to a pivot mechanism. This bar construction has a hip bar and one or more pivot arms integral with the hip bar, which bar construction is pivotable about the pivot axis from a raised position in which the hip bar is raised from the seating surface to allow a passenger to sit down in the amusement device seat assembly, to a lowered position. No part of the bar construction takes away the view of the person and limits the movements of the arms of the person, allowing the passenger to experience a great sense of freedom.
