Interior Space Design Optimization of Passenger Cars in Serbia

This study proves that in addition to the angles between the anthropometric measurements, passenger car interior space optimization in terms of ergonomic adjustment is most heavily influenced by the totals of the anthropometric measurements for lower leg length, upper leg length and sitting height for the same overall totals, which are individually different. The regularities of the anthropometric measurement mechanism as well as their geometry and kinematics of movement have been compared with the mechanical mechanism, so that according to new methodology the vehicle has been designed for wider range of drivers. The optimal space is defined within a coordinate system with the origin at the fixed "O" point of contact between the driver's heel and the car floor in front of the accelerator pedal. The designed optimal roof-floor space height for the driver along the z-axis amounts to 1250 mm, and the distance from the fixed "O" point backwards along the x-axis is 1180 mm, while the distance from the zero point for feet accommodation forwards along the x-axis equals 330 mm. The adjustability of the seat-floor height ranges from 190 mm to 300 mm. The horizontal movement of the seat amounts to 250 mm.
