Abstract
This paper describes a systematic layout method which is intended to define the seating package and body reference points in vehicle design, as well as determining the adjustment envelope required to fit a given range of population sizes.
Initially, the operational requirements of the vehicle are considered, including the number of occupants and their function. In addition, consideration is given to seat access and the application of restraint systems. Vehicle speed and type of manoeuvrability envisaged will have an effect on its body construction and suspension, and these factors are considered and balanced against a suitable posture for the occupants. The paper then considers the determination of a specification which should enable the designer to work out the function of seating, seat adjustments and restraint system anchorage points in a methodical manner.
The design layout method described takes into account the vehicle control pedals, facia, steering wheel and its range of adjustment where applicable, windscreen, roof lining, rear bulkhead, rear passengers, gear lever, and all other possible intrusions into the driver's workspace.
