Abstract
Urban bus act as a major transportation source for human population. Seat supporting frame is one of the important components of the bus which provides support for human weight. Currently, the supporting frame structure causes knee strain to the passenger sitting at the rear side of the seat. The aim of this research work is to improve the ergonomics design of the bus seat support frame in order to reduce bus passenger knee strain. The anthropometry data of passenger relevant to the ergonomic suitability of seat include seat depth, seat height, seat side clearance and support frame dimensions were measured. The passenger anthropometry variable includes buttock-knee length, sitting height,etc. RULA (Rapid Upper Limb Assessment) analysis was carried out for 95th percentile. Based on RULA analysis, alternate concepts are formed based on feasibility. For the selected concept, modelling and finite element analysis was carried out under various loading conditions. Based on the analysis results, optimum design was determined. Accordingly proof of concept prototype will be developed.
