Truck Driver Selected Seat Position Model 861131

A truck driver selected seat position tool has been developed to describe where certain percentages of truck drivers position horizontally adjustable seats in various workspace arrangements. The curves describe the 2.5th, 5th, 10th, 50th, 90th, 95th, and 97.5th percentile accommodation levels expressed as H point locations aft of the Accommodation Heel Reference Point as a function of vehicle H-point height (H30). Separate equations describe the accommodation level for driver populations with male/female percentages of 50/50, 75/25 and from 90/10 to 95/5. The equations can be used as a design tool to estimate the location and length of horizontal seat travel to provide accommodation of target percentages of truck drivers. The equations can also be used as a checking tool to estimate the level of accommodation provided by a given horizontally adjustable seat track.
