Malaysian sitting anthropometry for seat fit parameters

Abstract

This article presents sitting anthropometry data for Malaysians focusing on seat fit parameters. It offers additional data regarding seat design requirements as there have been only a few efforts made to establish anthropometry data in Malaysia. An analysis using a measurement composed of 16 common and important dimensions in seat design was done with 216 subjects. Data collection was done by using direct measuring methods with standard equipment. Malaysian automobile seat fit parameters, namely backrest width, backrest height, cushion width, and cushion length were established from collected anthropometric dimensions: interscye breadth (5th percentile female and 95th percentile male), sitting shoulder height (5th percentile female), hip breadth (95th percentile female), and buttock-popliteal length (5th percentile female), respectively. From the data collected, this study finds that the fit parameter dimensions are bigger than other Asians' 95th percentile values but smaller than the Filipino and the Thai data being compared in this study. The female 5th percentile values for cushion length and cushion width are the smallest. In addition, two local automobile seats were measured and compared with the data. It was observed that the cushion lengths of both seats were too long for the 5th percentile female of the current data. This study provides seat fit parameters-the most fundamental part of automotive seat design, especially for the Malaysian population. C 2010 Wiley Periodicals, Inc.

The relationship between anthropometry and hand grip strength among elderly Malaysians

“…Zakaria (2011) determined a sizing system for school uniforms. Daruis (2011) and Deros et al (2009) focused on improving chairs and seats for the Malaysian population, and the findings showed that the sitting dimensions of Malaysians are larger than the 95th percentile of other Asians. However, the sitting dimensions of Malaysians are smaller than those for Filipinos and Thais.…”

Postural Variabilities Associated with the Most Comfortable Sitting Postures: A Preliminary Study

“…In the evaluation of seats, different methods have been used to measure sitting comfort, such as anthropometry, subjective assessment, and objective measurements. In general, questionnaires are often developed to assess the comfort/discomfort levels for comparison purposes [ 23 , 24 , 25 ], whereas the anthropometric and biomechanical evaluations are used for chair designs [ 26 , 27 , 28 ] and load estimated on body regions [ 29 , 30 ], respectively. Body joint angle recoding is one of the methods for connecting the sitting posture and the comfort.…”

Ergonomic Perspective: Mismatch between Seat Drivers and Anthropometric Measures of Elderly Taxi Drivers in Malaysia

“…Previous studies have stated the differences in anthropometric data between ethnic groups, and there may also be differences in a population [19][20][21]. Differences in parameter values for driver seats also occur between Malaysia's anthropometric data from the previous study [16,[19][20][21][22][23]. However, this study only involves the elderly who are older than 60 years and above, and the total number of study respondents involved for anthropometric measurement is only 56 respondents obtained from secondary data [14].…”
