11、 stomach contours can be located in vehiclespace. Three different lines are provided to accommodate truck driver populations with male-to-female ratiosof 50:50, 75:25, and 90:10 to 95:5. (See SAE J1516.)3.5 Stomach Position Locator LineA series of two-dimensional side view lines which define the sto
12、machcontour x and z locations as a function of H-point height (H30). Three seats of locator lines are defined toaccommodate truck driver populations with male-to-female ratios of 50:50, 75:25, and 90:10 to 95:5. The threelines are defined using one of two methods.3.5.1 The x and z values for the sto
13、mach position locator lines can be obtained from the following equations:For 50:50 male-to-female mix:(Eq. 1)(Eq. 2)For 75:25 male-to-female mix:(Eq. 3)(Eq. 4)For 90:10 to 95:5 male-to-female mix:(Eq. 5)(Eq. 6)4. BackgroundThe stomach contours were obtained by developing data gathered during the Tru
14、ck DriverAnthropometric and Work Space Survey (see M. S. Sanders 1983 and B. E. Shaw and M. S. Sanders 1984).This survey utilized a static seating buck in which drivers were photographed in three seat heights for threedifferent configurations. From the photographs, two points were identified on each
15、 subject in the stomachregion. The first of the two points was the maximum forward protrusion of the stomach. The second point wasfound by determining the intersection of the drivers lap with the upper edge of a seat belt that was provided forsubjects during testing. Using photogrammetric techniques
16、, these two points were related in true scale andreferenced from the seat H-point. At this point, the data was separated by male and female and usingstatistical techniques, recombined to form four male-to-female population ratios of 50:50, 75:25, 90:10, and95:5. Ellipses were generated based on the
17、four population ratios representing 95th percentileaccommodation levels for the two data points, lap and stomach protrusion.x = 752.657 1.0461 H30()+()2 752.657 1.0461 H30 )()368.243 0.4462 H30()+(z 249.319 0.1127 H30()=x 765.65 1.0149 H30()+()2 765.65 1.0149 H30 )()391.943 0.4595 H30 )()+(=z 240.18

19、ations. The contours were drawn so as to encompass the lap ellipse, the protrusionellipse, and a point selected by the intersection of a horizontal line tangent to the top of the protrusion ellipseand a vertical line tangent to the front of the protrusion ellipse. The stomach contours were fit first
20、 by a best fitcurve procedure and adjusted from there to fit the criteria stated previously. Due to curve similarities, thelocating lines for the 90:10 and 95:5 male-to-female population ratios were combined.There is one general curve which can be used to accommodate drivers in heavy truck design fo
21、r three rangesof male-to-female population ratios. These curves are representative of stomach locations in a truckenvironment and can be used to provide stomach definition.5. Application5.1 The stomach position contours provide a drafting tool from which driver stomach locations can be described inv
22、ehicles with horizontally adjusted seats.5.2 The stomach position contours are applicable only to motor vehicles, whether trucks, buses, or multipurposepassenger vehicles with bucket or bench seats, that are within the following range of driver workspacedimensions:a.

Stomach Position Contour Locator6.1 Use the method described in SAE J1516 to locate reference line in vehicle space. Select the point on this linea
24、t the workspace H-point height (H30). This point defines the stomach contour reference station.6.2 Use the appropriate stomach position locator line for the population mix to be accomodated.
