Abstract

In this project is to design a comfortable bus passenger seat by integrating air-based and gel-based material. This is due to most of the express coaches are using polyurethane foam based cushion in the seat padding. This type of the seat padding will cause a bus passenger who sit for long journey will feel uncomfortable and fatigue. There are two main causes which lead to uncomfortable and fatigue which is vibration of drive vehicle and pressure distribution on the seat. There was a bus passenger seat survey conducted to identify the most uncomfortable body part during the bus travelling. In this research will emphasize the integrated design of a bus passenger seat to ensure maximum comfort to the bus passenger. The new design a bus passenger seat is using air-based and gel-based cushion to increase the comfortable parameters in the bus. After the brainstorm session, it contributed new ideas and come out with the best concept from the weighted objective evaluation. The selected concept was validated by using MatLab SimuLINK software. In the model validation had determine some of the parameters gave effect on the pressure change rate of air cushion model. The comfortable level of the air cushion could be improvement by reduce the pressure change rate. All the changing parameters were compared and discussed in this discussion section to show the improvement brought by this new design of bus passenger seat. In the final results shown that the height of air cell and the stiffness of air cell gave an impact of the comfortable bus passenger seat.
