Summary:

Two alternative methods are presented for studying the comfort, and possibly fatigue, effects of vehicle seats, in particular truck seats that include a seat suspension. The methods, named "aPcrms" and "SPD%" for the purpose of this study, are based on analyzing the pressure profile at the seat cushion/human body interface in a manner that accounts for the contact area, pressure distribution, and change in contact pressure. The alternative methods are compared with methods suggested in the past for vehicle seats, using a laboratory test rig and a truck seat with a conventional foam cushion and an air-inflated seat cushion. The results show that the proposed methods better highlight the human comfort differences between the two cushion types, and provide objective measures that better correlate with subjective measures from a separate field study on the same types of seats
