The best commonly applied approach in seating ergonomics is the concept that the seat must fit the sitter.Understanding of population anthropometry is necessary because, in the mass vehicle market, a single seat should fit a huge portion of the population. This research work proposes some automotive seat fit parameters based on a representative Nigerian anthropometric data, to ensure an optimum fit between the vehicle seats and the occupants, as well as providing adequate accommodation. Anthropometric data of 863 Nigerians captured with special emphasis on the dimensions that are applicable in automotive seat design. A comparison made between the data obtained and that of five other countries. The proposed dimensions includes: seat cushion width (475mm); seat cushion length (394mm); seat height (340mm); seat lateral location (583mm); seat back height (480mm); seat back width (427mm); armrest height (246mm); headrest height (703mm); armrest surface length (345mm); backrest width (thoracic level) (524mm); seat adjustment (186mm); backrest width (lumbar level) (475mm) and distance between armrests (475mm). A comparison made between the proposed dimensions and those recommended by four other scholars for other populations. Finally, an ergonomic automotive seat suitable for the Nigerian population was designed using AutoCAD 2016 software based on the proposed established dimensions

Anthropometric study is one of the oldest branches of study in ergonomics where it serves a purpose in study of proportion and size for human body. One of the common methods used in anthropometric measurement is traditional measurement or direct measurement. However, Malaysia is still left behind other countries in development of national anthropometric database. Researchers in Malaysia are still relying on the traditional anthropometric (TA) measurement. There are several important factors that contribute to problems in TA such as accuracy, time, posture, identification of landmarks, instrument positions and orientations, and pressure exerted due to measuring equipment. In view of the fact that the difficulties of obtaining human anthropometry, it becomes necessary to propose a method which has less contact executed to respondent. This study aims to propose a new anthropometric measurement method using motion capture camera (MCC) method, later to develop the database for youth male population. A pilot test was done in order to confirm the measuring procedure as well as the flow of the study. Next, the Minitab statistical software used to check the validity and reliability of data using the tests of a) Accuracy-Pearson/Spearman Correlation b) BiasPaired T-Test c) Test-Retest Reliability-Pearson/Spearman Correlation d) Precision-Mean Absolute Difference and Relative Error Measurement. Results showed that the validity and reliability of this motion camera has successfully obtained and the anthropometric data for youth male respondents has successfully constructed. These findings can be used and expended to the national anthropometric database to be utilised in ergonomics design.
