Movable sub-assembly for accommodating and conveying at least one passenger and associated attraction installation

An attraction installation comprising at least one stationary structure, and at least one movable sub-assembly for accommodating and conveying at least one passenger, the sub-assembly comprising a support, a cabin, and a guide for rotationally guiding the cabin relative to the support about a reference axis common to the support and to the cabin, the reference axis being horizontal when the movable sub-assembly is in an operational state, the movable sub-assembly being equipped with a stabilization system comprising at least one toothed ring rigidly connected to the support and centered on the reference axis, at least one first gear supported by the cabin so as to mesh with the toothed ring, and drive means capable of driving the first gear, wherein the first gear is supported by the cabin so as to mesh with a zone of the toothed ring that is located above the first gear, wherein the sub-assembly is guided relative to the stationary structure in such a way that the support follows a trajectory that forms a loop in a vertical plane of a fixed frame of reference, and which, with respect to a fixed axis of rotation that is perpendicular to the vertical plane and parallel to the reference axis, makes a rotation of 360° by completing a lap of the loop-shaped trajectory.
