Truck Driver Shin-Knee Position for Clutch and Accelerator

2014-12-03
CURRENT
J1521_201412
This SAE Recommended Practice describes two-dimensional, 95th percentile truck driver, side view, seated shin-knee contours for both the accelerator operating leg and the clutch operating leg for horizontally adjustable seats (see Figure 1). There is one contour for the clutch shin-knee and one contour for the accelerator shin-knee. There are three locating equations for each curve to accommodate male-to-female ratios of 50:50, 75:25, and 90:10 to 95:5.

Location and Operation of Instruments and Controls in Motor Truck Cabs

HISTORICAL
J680_198809
The location and operation of instruments and controls herein described are recommended for adoption by manufacturers of trucks and truck-tractors in new or revised designs in order to avoid confusion when drivers shift from one truck to another, to promote safety and convenience, and to simplify design, production, and servicing. This recommended practice shall apply to all on-highway trucks and truck-tractors equipped with power brake systems and having a GVW rating of 26 000 lb or more. Of prime importance in this recommended practice is the basic premise that all controls requiring operation while the vehicle is in motion be located so that the driver can manipulate them with his right hand and keep his left hand on the steering wheel. Controls operated only when the vehicle is not in motion, such as the ignition key, starter switch, and engine shutdown, may be located at the left side of the instrument panel and be manipulated with the driver's left hand.

Driver Selected Seat Position

1998-12-01
HISTORICAL
J1517_199812
A driver selected seat position tool has been developed to describe where certain percentages of drivers position horizontally adjustable seats in various workspace arrangements. The tool consists of series of equations that describe horizontal H-point locations as a function of vehicle H-point height (H30). One series of equations have been established for use in vehicles with H-point heights (H30) and steering wheel diameters (W9) less than 405 mm and 450 mm, respectively (Class A Vehicles). This class of vehicles includes passenger cars, vans, and light trucks. The lines describe the 2.5th, 5th, 10th, 50th, 90th, 95th, and 97.5th percentile accommodation levels expressed as H-point location for a driver population with a male-to-female ratio of 1:1.
