Abstract
Abstract A suspended operator station within the cab of a tractor or similar vehicle adjusts the height of the seat and thereafter the positions of the steering wheel, foot pedals and other controls relative to the seat for maximum visibility and comfort of operators of different size, and permits attenuated movement of the seat and controls together. The seat is mounted on a platform which is suspended above the cab floor by an attenuator assembly permitting limited, attenuated movement of the platform in a generally horizontal plane and a height adjustable support having vertical shock absorption and which positions the height of the seat for optimum visibility. The seat is mounted on the platform via tracks which permit fore-aft adjustment of the seat relative to controls coupled to the platform. In one embodiment a tiltable and telescoping steering wheel and foot pedals are mounted on a subfloor which is coupled to and adjustable in height relative to the platform. In an alternative embodiment the foot pedals are mounted on the platform and a tiltable and telescoping steering wheel is mounted on a console extending from the armrest of the seat.
