What are the seats directly attached to on the Cobra roller coaster at the Tivoli Friheden amusement park?
Inverted roller coaster An inverted roller coaster is a roller coaster in which the train runs under the track with the seats directly attached to the wheel carriage. This latter attribute is what sets it apart from the older suspended coaster, which runs under the track, but "swings" via a pivoting bar attached to the wheel carriage. The coaster type's inverted orientation distinguishes it from a traditional roller coaster, where the passengers' legs rather than arms are exposed.
Roller coaster inversion A roller coaster inversion is a roller coaster element in which the track turns riders upside-down and then returns them to an upright position. Early forms of inversions, dating as far back as 1848 on the Centrifugal Railway in Paris, were vertical loops that were circular in nature. They produced massive g-force that was often dangerous to riders, and as a result, the element eventually became non-existent with the last rides to feature the looping inversions being dismantled during the Great Depression. In 1975, designers from Arrow Development created the corkscrew, reviving interest in the inversion during the modern age of steel roller coasters. Since then, the element have evolved from simple corkscrews and vertical loops to more complex inversions such Immelmann loops and cobra rolls. Featuring fourteen inversions, The Smiler at Alton Towers holds the world record for the number of inversions on a roller coaster.
