“…This could be due to smooth road surfaces and high quality vehicle suspension [10]. In this case, the dynamic seat factors are less important than the static seat factors and therefore improved comfort could be achieved by optimising the static factors (such as seat stiffness, fit/adjustments, and seat shape).…”

Occupants of automobiles experience discomfort after long drives, irrespective of how well designed a seat might be. Previous studies of discomfort during driving have focused either on the seat shape and materials ("static" properties), long-term discomfort ("fatigue" properties), or dynamics ("vibration" properties). These factors have previously not been considered together. This paper reports three studies with objectives to define and test a model for describing long-term discomfort from vibration. Study 1 was an independent measures laboratory trial using an automobile seat, which lasted 80 minutes; Study 2 was a repeated measures laboratory trial using a rail passenger seat, which lasted 60 minutes; Study 3 was a repeated measures field trial in a people carrier automobile, which involved 70 minutes of travelling. The findings showed that discomfort accrues with time but that more discomfort is experienced when subjects are also exposed to whole-body vibration. Exposure to whole-body vibration accelerates development of discomfort. The relationship between the reported discomfort, the vibration magnitude, and the exposure time can be described using a multifactorial linear model. It is concluded that ignoring parts of the multi-factorial model (i.e., static, dynamic, or temporal factors) will compromise understanding of discomfort in context.

“…Por exemplo, as dimensões (altura e largura) do contorno lombar de dois assentos eram idênticas, mas não foram percebidas com o mesmo nível de conforto, sugerindo que a região lombar possa ser afetada pelo conforto da coxa. O autor sugere que conforto de assento seja estudado extensivamente relacionando outras variáveis, além de antropometria e ângulos posturais (KOLICH et al, 2004).…”

RESUMOO presente estudo é parte de um projeto integrando ergonomia ao projeto Baja SAE. Um dos objetivos foi analisar o desconforto percebido pelos pilotos ao conduzir dois veículos, o Baja Antigo (BA) -modelo 2013 -e o Baja Novo (BN) -modelo 2015. Em média os pilotos sentiram maior desconforto após conduzirem o BN, sendo as regiões das costas as que sofreram maior impacto. As repostas dadas pelos pilotos foram contrastadas com os ângulos posturais, sendo aqueles que mais diferem dos ângulos de conforto sugeridos pela literatura, os correspondentes às regiões corporais com maior incômodo ou dor. ABSTRACT The present study is part of an ergonomics research project involving the Baja SAE project. One of the objectives of the study was to analyse the body areas of discomfort among pilots of the old Baja (BA) -used in competitions in

“…Therefore, the PPOSB is one of design features for the car seats of a passenger car. Many studies have been conducted on car seats from the perspective of ergonomics engineering [13,6,11,3]. The transmission of vertical vibration through seats is has been researched [13].…”

“…Research on the prediction of seat comfort has been done based on an artificial neural network. In that study, the overall comfort index for a seat was developed and applied to the automobile seat design process [6]. The effect of heated seats in vehicles has been studied to reduce heater energy.…”
