“…Fixed postures from prolonged driving involve static muscle work and consequently blood vessel constriction, particularly in the spine, buttocks and thighs. This static loading of the driver requires musculature to be enlarged, which causes vasoconstriction and consequently blood flow restrictions (Kolich et al, 2001;Sheridan et al, 1991). As a result, local circulatory disruptions occur such that oxygen delivery, nutrient reserves and the removal of metabolic by-products are compromised.…”

Engineering movement into automotive seating: Does the driver feel more comfortable and refreshed?

The concept of introducing movement in automotive seating was investigated. Three seat conditions, a control (no movement) and two movement conditions (fore-aft and cushionbackrest) were compared. Movement was introduced at a fixed speed, slow, smooth and within a small range. Ten participants took part in a 60 minute simulated drive for each condition-single blind, repeated measures, and balanced order. Discomfort ratings were collected for six body areas and overall discomfort, together with a wellbeing questionnaire. Driver posture and Seat Fidgets and Movements (SFMs) were captured. There was a trend for lower ratings of discomfort, overall and in the neck, shoulders, lower back, buttocks, and ankles with both seat movement conditions. Wellbeing ratings were also better with movement. Significant differences were found at minute 60 for buttock discomfort-less discomfort with seat movement. Overall discomfort and SFMs frequency increased with time driving. Generally, passive seat movement was well received.

“…electrodes, amplifier, personal computer), the fact that the electrodes may be perceived as annoying and may, therefore, negatively affect perceptions of comfort, and the considerable amount of time it takes to obtain a measurable effect. While some automobile seat comfort researchers are turned off by these limitations, others have continued to use EMG as an objective indicator of fatigue (Kolich et al, 2000(Kolich et al, , 2001Bush et al, 1995;Greiff and Guth, 1994;Lee and Ferraiuolo, 1993;Sheridan et al, 1991). Unfortunately, the research has failed to produce standards for acceptable EMG levels.…”

“…Evaluation methods that provide insight into human physiology and biomechanics are, therefore, currently being examined. Recent advances in sensing technologies have allowed for new and improved characterization of the occupant-seat interface (Park and Kim, 1997;Sheridan et al, 1991). The application of these technologies permits a wide variety of experiments to be conducted, in real-time, without requiring modification to the seats under investigation.…”

This study conducted a series of road tests in the regular fleet operations of a revenue service to better understand the relationship between vehicle seat design and driver fatigue, improve two newly proposed objective methods for evaluating driver fatigue, and provide design guidelines for evaluating and improving vehicle seat characteristics in terms of driver fatigue. Each driver completed a test session on two seat cushions-one a polyurethane foam cushion and one an air-inflated cushion. Objective measurements of pressure distribution were taken throughout each test session, while subjective measurements were collected using surveys taken at one-hour intervals. Based on these results, we find that the air-inflated seat cushion has advantages in terms of subjective measures of comfort, support, and fatigue. We show that the objective measure aPcrms highlights characteristic differences between seat cushions, as the airinflated seat cushion provides less area in high pressure regions, thus occluding less blood flow to tissue in the seated area. While we were unable to effectively assess the validity of the proposed measures or improve them further, the characteristic difference between seat cushions is not highlighted by using previously existing objective measures. This implies that aPcrms is a more useful measure and should be considered when evaluating the subjective quality of seat cushion designs under dynamic conditions, such as those existing in commercial truck driving.
