a motion simulation chair incorporates a base providing elevated attachment points for a number of support cables . a seat support is carried within the base and engages a seat for an occupant at a top end . the seat support has companion attachment points for the support cables at a bottom end . a control system incorporates a forward vertical control element constrained for three axis motion about a control point . a horizontal control element displaced upward from the control point and extending rearward from the forward vertical control element , engages the seat support . a control stick operated by the user imparts motion to the forward vertical control element about the control point . moving the horizontal control element alters the suspension angles of the cables providing a corresponding tilt of the seat support and seat for realistic simulation of motion resulting from inputs to a computer game by the control stick .
