Abstract: A roller coaster installation comprising a stretch of water, along which runs a train of vehicles (104) provided laterally with hydrodynamic brakes comprising a fin (102) or a nozzle, becoming immersed in the mass of water (A) and discharging this in the form of rising sprays (B).

Abstract: A roller coaster circuit comprising a pool of water, which is run alongside or crossed, via a dry channel, by a train of vehicles provided laterally with water brakes consisting of a nozzle becoming immersed in the body of water and throwing the latter out in the form of upward sprays.

Abstract: The installation for amusement park, referred to as roller coaster, comprises a circuit made up of rails (6), mounted on supports (10), themselves fixed on a carrier beam (11), on which one or more vehicles run, designed to run on the rails, as opposed to a suspended roller coaster, and at least one station for the embarkation and disembarkation of passengers. Each vehicle comprises a main beam (1), at least one transverse chassis element (2) on which are mounted, on the one hand, wheels (3, 4, 5) interacting with the rails (6), and, on the other hand, seats (7) provided with retention means (8). The station, which comprises at least one platform (12) likewise comprises a fold-away floor (14), which replaces the floor, absent of the vehicle, when the vehicle is stopped in a predetermined position for embarkation and disembarkation. Due to this, the vehicle may be designed without any floor.

Abstract: The installation for amusement park, comprises at least one vehicle designed in such a way as to be able to accommodate at least one passenger in at least one seat, associated with at least one retention device. The retention device comprises a pivoting bar mounted on a retention element intended to retain the passenger in the seat. The retention element features a complex spatial shape, of which the lower part, intended to come in contact with the passenger's thighs, comprises for this purpose two recesses forming a hollow corresponding approximately to the size of the passenger's thighs.

Abstract: The amusement ride comprises at least one seat suspended on a bogie moving along at least one rail. The seat is provided with a harness for the restraint of at least one passenger in the seat. The seat-harness unit is shaped so as to form a restraint imprisoning the passenger's body when the harness is in the closed position, each of the passenger's four limbs emerging from said restraint through a separate opening, so that the passenger is suspended with his legs in mid-air without a wall or a floor around him.
