註釋"This study was undertaken in order to evaluate certain design characteristics of the C-97A/KC-97E Pilot Seat (Weber) in terms of their adequacy for the maintenance of human comfort The method of evaluation consisted primarily of a battery of subjective and behavioral laboratory tests administered by means of hourly questionnaires presented to sixteen subjects during a voluntary sitting period of seven hours' maximum duration. While the permitted maximum duration of sitting time was 420 minutes, the average voluntary time spent in the seat was 365.6 minutes. On a comfort scale ranging from intolerable discomfort (-10) to ideal comfort (+10), the average of the ratings assigned was +3.57. Hourly scale evaluations of the comfort of the seat revealed that, although the comfort provided decreased with time, at no point during the first five hours did the average rating fell into the discomfort zone. Hourly evaluation of discomfort in specific body regions indicated that for all body regions the average time of onset of discomfort was 198.0 minutes, and that the most discomfort was experienced in the buttocks, back, and neck, in that order. Evaluation of individual seat parts revealed certain inadequacies in the seat and back cushions, armrests, headrest, and manipulative aspects of the adjustment controls. On the basis of test data and specific comments made by the subjects, recommendations for seat design improvement are made."--Abstract.
