An amusement ride providing a theatre with a screen and having a motion base, wherein the motion base comprises: - a support structure, defining a stationary portion of the motion base; - a pivot structure defining a rotating portion of the motion base and supported on top of the support structure, whereby the pivot structure has a pivot point near the center of gravity of the pivot structure; - a platform slidably mounted on the pivot structure on top of guiding members to allow the motion base to move along a heave axis via operation of an actuator and a counterbalancing member, wherein the platform has a horizontal operational position and a vertical operational position, - a drive comprising an actuator for rotating the pivot structure at the pivot point to move the platform from the generally horizontal position to the generally vertical position, whereby at least one counterbalancing member is provided for generating a force opposite to the force generated by rotation of the pivot structure, wherein the platform comprises: at least two seats arranged longitudinally and mounted on the platform with seat frame brackets; a seat drive member; a seat actuating member engaging the at least two seats longitudinally and coupled to the seat drive member; wherein pitch of the at least two seats is adjustable simultaneously by action of the seat drive member engaging the seat actuating member, wherein the motion base is capable of providing three degrees of freedom to the seats, namely movement about a pivot axis, along the heave axis, and about a seat pitch axis, the movement around the seat pitch axis being facilitated by mechanisms driving the seats. - a support structure, defining a stationary portion of the motion base; - a pivot structure defining a rotating portion of the motion base and supported on top of the support structure, whereby the pivot structure has a pivot point near the center of gravity of the pivot structure; - a platform slidably mounted on the pivot structure on top of guiding members to allow the motion base to move along a heave axis via operation of an actuator and a counterbalancing member, wherein the platform has a horizontal operational position and a vertical operational position, - a drive comprising an actuator for rotating the pivot structure at the pivot point to move the platform from the generally horizontal position to the generally vertical position, whereby at least one counterbalancing member is provided for generating a force opposite to the force generated by rotation of the pivot structure, wherein the platform comprises: at least two seats arranged longitudinally and mounted on the platform with seat frame brackets; a seat drive member; a seat actuating member engaging the at least two seats longitudinally and coupled to the seat drive member; wherein pitch of the at least two seats is adjustable simultaneously by action of the seat drive member engaging the seat actuating member, wherein the motion base is capable of providing three degrees of freedom to the seats, namely movement about a pivot axis, along the heave axis, and about a seat pitch axis, the movement around the seat pitch axis being facilitated by mechanisms driving the seats. at least two seats arranged longitudinally and mounted on the platform with seat frame brackets; a seat drive member; a seat actuating member engaging the at least two seats longitudinally and coupled to the seat drive member; wherein pitch of the at least two seats is adjustable simultaneously by action of the seat drive member engaging the seat actuating member, wherein the motion base is capable of providing three degrees of freedom to the seats, namely movement about a pivot axis, along the heave axis, and about a seat pitch axis, the movement around the seat pitch axis being facilitated by mechanisms driving the seats.
