Abstract: The disclosure provides a frame assembly for suspending a rider from a trolley moving along a rail in a longitudinal direction. The frame assembly includes a bar fixedly mounted to the trolley transverse to the longitudinal direction. The frame assembly also includes a frame including: a horizontal segment positioned above a location for the rider; at least one vertical segment extending from the horizontal segment; and a substantially horizontal platform suspended from the vertical segment. The frame assembly also includes a pivot assembly including a first portion coupled to the trolley and a second portion coupled to the horizontal segment. The pivot assembly includes at least two axis of rotation between the first portion and the second portion. The frame assembly also includes a sway limiter connected between the bar and the horizontal segment limiting a range of movement of the pivot assembly.
