Abstract: An alpine ski simulator for reproducing the basic corporal movements involved in downhill skiing, comprising a frame which may be set at different angles relative to the horizontal plane, and a handrail for equilibrium purposes. A rotatable platform, horizontally mounted on the frame through a central shaft has roller means set between the platform and the frame to ease the rotation. A fixed band encircling the platform, guided between two pairs of posts, and connected to the frame, is provided for braking purposes. Adjustable means are attached between the band and the frame to increase or reduce the tension of the band against the platform and thus, vary the rotational speed of the platform.
