Abstract

Automotive ergonomics is the study of how automotive can be designed better for human use. Improper design and uncomfortable seats imposes a lot of stress upon different body parts of driver. It is the driver who gets more fatigue than the passengers. If the driver seat is not comfortable the comfort or discomfort factors can lead to various injuries related to car seat design. The project is based on the human analysis and ergonomics for the seat design of the electric buggy. The buggy seat is a seat placed in a limited space, which when in motion, undergoes dynamic forces, among which the centrifugal force, plays an important role to cause discomfort to the driver. Engineers may design cars to be ergonomically friendly, it doesn't mean that one design will work for all users, especially if the car is designed for a person of certain proportions. The finding is expected to explain and give better understanding about the ergonomic driver seat design for electric buggy. Based on the anthropometric measurement data and the ergonomics principles, the buggy driver seat can be improved by using RULA analysis method. The results and discussion is analyzing the electric buggy seat and design the ergonomic buggy driver seat in order to prevent musculoskeletal. The data that has been collected such as the dimension of the electric buggy and the correct posture used by the driver has been used to complete the design and analysis. The primary focus for this chapter will be on the redesign the electric buggy driver seat for improving the body posture of the driver and validate the redesign electric buggy driver seat based on the RULA analysis. Based on the RULA analysis and the results shown, it proved that the modified design of the electric scooter seat design is better than the existing design. The most crucial part is the distance between the buggy roof and the seat, which give big effect to the comfort of the rider. Besides, the height of the seat also gives an impact to the posture of the driver during driving the electric buggy.
