Abstract

The development of ergonomic is developed and recognized during the Second World War. This is because, for the first time, human technology and science are applied together systematically. Word ergonomic comes from the Greek Word meaning work law. Some countries used the terms human factors. The ergonomics purpose to design appliances, technical system and tasks in such way as to improve the safety of human, health, comfort and performances. The project is based on the human analysis and ergonomics for the seat design of the electric scooter. The scooter 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 the electric scooter to be ergonomically friendly, it doesn't mean that one design will work for all users, especially if the electric scooter is designed for a person of certain proportions. The finding is expected to explain and give better understanding about the ergonomic seat design for electric scooter. Based on the anthropometric measurement data and the ergonomics principles, the electric scooter seat can be improved by using RULA analysis method. The results and discussion is analyzing the electric scooter seat and design the ergonomic electric scooter seat in order to prevent musculoskeletal. The data that has been collected such as the dimension of the electric scooter and the correct posture used by the rider has been used to complete the design and analysis. The primary focus will be on the redesign the electric scooter seat for improving the body posture of the rider and validate the redesign electric scooter 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 handle 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 rider during riding the electric scooter.
