Abstract: An amusement device seat includes a seat and a bar construction, moveable between an access position to a passenger fixation position, in which the passenger is fixed in the seat. The assembly further includes a locking device to lock the bar construction at the passenger fixation position. The locking device includes an engagement device to engage and disengage with the bar construction and a guide for the engagement device allowing the engagement device to assume an engagement position between the access position and the passenger fixation position, and allowing the engagement device and the engaged bar construction to move between the engagement position to the passenger fixation position. The locking device includes a fixation device for fixing the engagement device and the engaged bar construction at multiple passenger fixation positions along the guide to accommodate passengers of different sizes.

Abstract: An amusement device, in particular a roller coaster, for providing a sense of excitement to one or more passengers using the amusement device. The 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. The bar construction is such that 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.
