摘要： An amusement device includes a substructure with a passenger seat, which is rotatable relative to a main structure by a bearing and a coupling. The coupling has a coupling ring and a coupling actuator for driving the substructure about a coupling axis C-C. The coupling ring has an end face which is toothed to engage with a toothed end face of a lock element of a lockage for rotationally locking the coupling ring with respect to the main structure. The lock element is axially movable and rotationally constrained with respect to an lockage actuator. A spring and electromagnet respectively serve for axially moving the lock element. During a normal ride, the lockage is open and all kind of rotations are possible, but in case of an interference the lockage engages for safety.
