US Patent 11992780 Roller coaster vehicle

A roller coaster vehicle is disclosed with seats that are mounted to a circular frame, and where the seats and the frame swing about a central horizontal axis passing between the seats, while the vehicle moves along a standard roller coaster track. The swinging or rotating of the seats with respect to the reference frame of the vehicle leads to a more intense riding experience. In a first preferred embodiment, the seats rotate passively in response to various gravitational and centripetal forces caused by the movement of the car along the track, but the seats could also be actively rotated by motors or other mechanical elements.
