“…There have been many past research and experiments conducted in driver's car posture (Na et al, 2005;Hirao et al, 2006;Hermanns et al, 2008;Falou et al, 2003;Park et al, 2000;Andreoni et al, 2002;Kyung and Nussbaum, 2008;Reed et al, 2000;Sun et al, 2006) but none was conducted for the Malaysian population. So, this study is aiming to publish comfortable and safe driving postures as preferred by Malaysian car drivers.…”

Problem statement:The purposes of this study are twofold: First, to recommend a range of angles for driving posture comfort from measurement of participants and second, to investigate the relationships between drivers' anthropometric characteristics, comfortable postural angles and seat adjustment. Approach: Forty five participants were involved in the study. Both anthropometric data and postural angles were measured and recorded by using the photographic technique and analyzed further using software. During the study, each participant was required to sit on the driver's seat in his or her preferred comfortable driving postures. Images of the participant's driving posture were taken after 5 min he or she has been in the driving position to allow him/her to adapt with the seat environment and fabrics. The seat adjustment data were measured manually after the seat is adjusted for comfort by the participant. Prior to that, 10 anthropometric data of each participant was measured and recorded. Data on comfortable driving postural angles, anthropometry and seat adjustment were analyzed statistically with Pearson correlation using the SPSS software. Results: From the study, a range of angles are proposed based on the participant's perception on comfort. The ranges of comfortable angles for Malaysian citizen proposed shows significant different between Caucasian and Korean populations. The relationships between the comfortable postural angles, anthropometric data and seat adjustment were analyzed and discussed with several outcome shows that taller participants preferred a driving posture with their arms outstretched in order to achieve comfort, participants with bigger body dimension have a tendency to sit farther back from the steering wheels and smaller participants prefer to sit closer to the steering wheels with a slightly greater trunk thigh angle. Conclusion: The result obtained and discussed in this study can be applied in the driver's car seat design and construction to ensure comfort and safety.

“…A total of 20 joint angles were evaluated in relation to the sitting posture and body motion tasks. The definition of joint angles was made with reference to G. Andreoniet et al [20] , and with reference to other joint angle definition conventions as well. Using a self-developed program in MATLAB, the joint angle were calculated, and compared with the occupational health analysis, like fatigue etc.…”

Most of the previous studies on the vibration ride comfort of the human-vehicle system were focused only on one or two aspects of the investigation. This paper proposed a hybrid approach which integrates all kinds of investigation methods in real environment and virtual environment. The real experimental environment includes the WBV (whole body vibration) test, questionnaires for human subjective sensation and motion capture. The virtual experimental environment includes the theoretical calculation on simplified 5-DOF human body vibration model, the vibration simulation and analysis within ADAMS/ Vibration TM module, and the digital human biomechanics and occupational health analysis in Jack software. While the real experimental environment provided realistic and accurate test results, it also serves as core and validation for the virtual experimental environment. The virtual experimental environment takes full advantages of current available vibration simulation and digital human modelling software, and makes it possible to evaluate the sitting posture comfort in a human-vehicle system with various human anthropometric parameters. How this digital evaluation system for car seat comfort design is fitted in the Industry 4.0 framework is also proposed.

“…Conversely, the review by De Looze [43] shows that the pressure distribution of the ischial tuberosity has been generally used for seats studies as there is a clear association with discomfort scales [15,27,29]. Other than being a noninvasive method, it enables the estimation of the intervertebral disc compression based on biomechanical models [30].…”

This work aimed to develop a mathematical model to evaluate the effect of seat inclination using as input the biomechanical characteristics of the user. The biomechanical model includes weight, posture, flexion of the pelvis and trunk and 5º and -5º seat inclinations. Using actual data collected during an experiment with 26 participants, a validation process was carried out to measure the model's ability to correctly predict load values on the ischial tuberosity. The results show a consistent model with an accuracy of 82% and a predictive quality of pred (25) = 0.77. Another outcome of the study is an equation to calculate the intradiscal pressure based on the load at the ischial tuberosity. The biomechanical model and the equations can be used to assess the effects of inclination of the seat and its backrest in chair design processes.Keywords: Biomechanical, driving activities tilt, sitting posture, intradiscal load. RESUMENEste trabajo se orientó al desarrollo de un modelo matemático para evaluar el efecto de la inclinación de la silla teniendo en cuenta las características biomecánicas del usuario. El modelo incluye el peso corporal, la postura, la flexión de la pelvis y el tronco, y se consideran inclinaciones en el asiento de 5º y -5º. A partir de la información recogida durante un experimento con 26 participantes se realizó un proceso de validación para medir la habilidad del modelo para predecir correctamente los valores de la carga en la tuberosidad isquiática. Los resultados muestran que el modelo es consistente puesto que su precisión es de 82% y la calidad de predicción de pred (25)= 0,77. Se desarrolló también una ecuación para calcular la presión intradiscal a partir de la carga en la tuberosidad isquiática. El modelo biomecánico y sus ecuaciones pueden ser utilizados para analizar los efectos de la inclinación de la silla y de su espaldar en los procesos de diseño de asientos.Palabras clave: Biomecánica, inclinación del asiento, postura sedente, carga intradiscal.
