Abstract: Computer simulation control system, comprising: at least one control module (1, 2) for controlling a computer simulator program; a seat comprising a seat part (3) and a back support; at least one mechanism (5) for coupling the seat and the at least one control module (1, 2) to each other in such a way, that that a user can be seated on the seat part (3) of the seat for handling the at least one control module (1, 2) there-from; wherein the back support of the seat is movable between a first position, in which first position the back support extends at an operating angle (?) upwardly from said seat part (3) for supporting at least part of the back of a user, and a second position, in which second position the back support does not extend at said operating angle (?) upwardly from the seat part (3), for example for transportation and/or storage of the control system.
