JUL2002 Issued1973-09 Revised2002-07 Superseding J1100 FEB2001 (R) Motor Vehicle Dimensions 1.ScopeThis SAE Re

5、commended Practice defines a set of measurements and standard procedures for vehicle dimensions. The dimensions are primarily intended to measure the design intent of a vehicle within a design environment (i.e., CAD). All dimensions in this practice can be measured this way. In addition, some dimens

6、ions can be taken in an actual vehicle. If measurements are taken on physical properties, some differences in values should be expected. Also, care should be taken to not confuse design intent measurements with those taken on a physical property. Unless otherwise specified, all dimensions are measur

7、ed normal to the three-dimensional reference system (see SAE J182), except ground-related dimensions, which are defined normal to ground. All dimensions are taken with the vehicle at curb weight unless otherwise specified. All dimensions are measured on the base vehicle and do not include Regular Pr

8、oduction Options (RPO) or accessory parts, unless otherwise specified. Although many terms and dimensions use human body parts in their name, they should not be construed as measures that indicate occupant accommodation, capabilities, or comfort. 2.References 2.1Applicable PublicationsThe following

The dash panel is usually the vertical extension of the toe panel. 3.5.10HEAD POSITION CONTOURSee SAE

27、J1052. Dimensions specified in this practice are measured from sections cut through the appropriate 95th percentile head contour. After the head contour is constructed and oriented, sections are cut normal to grid in side view and rear view through the ellipse centroid. The side view section is used

28、 for L38, L39, and H41. The rear view section is used for W27, W35 and H35. 3.5.11NORMAL TOP OF FRAME-TRUCKThe longest normal surface of the top flange of the truck frame within the wheel base. SAE J1100 Revised JUL2002 -4- 3.5.12UNDEPRESSED FLOOR COVERINGThe surface of the floor covering at a desig

29、nated point in the vehicle, without any load applied to the covering. 3.6H-Point Devices Reference Points and Definitions (See SAE J826)H-Point devices are used to establish key reference points and dimensions in the vehicles interior. The most critical reference point established is the H-Point. Th

30、ere are two types of devices that can be used to define the location of an H-Point; the H-Point Machine (HPM) and the H-Point Design Tool (HPD). The HPM is a physical device used in physical properties for the purpose of auditing and benchmarking. The HPD is a CAD tool used during design for establi

31、shing the occupant package. H-Point devices have a number of parts, including cushion pan, back pan, lower leg segment, thigh segment, shoe tool, and head profile. The back pan consists of three segments; pelvic, lumbar, and thoracic. In addition, the HPM uses 24 weights, and has a number of scales,

32、 readouts, and mechanical linkages. Terms and reference points related to the shoe tool are listed separately in 3.7. This document is supplemental to the procedures addressed in SAE J826. It is a reference for key terms and definitions. However, it does not provide sufficient information for someon

33、e to properly position and use an H- Point device. 3.6.1BACK LINEA line in side view, connecting the H-Point to the “sliding thorax pivot” (at the upper end of the thorax line) on an H-Point device. The angle of this line from vertical defines back angle. (See Figure 3.) 3.6.2CUSHION LINEA line in s

34、ide view, forward from the H-Point, parallel to the top of the cushion pan assembly of an H-Point device. The angle of this line from horizontal defines cushion angle. (See Figure 3.) 3.6.3D-POINTA point on an H-Point device located on the bottom surface of the cushion pan, at the lateral centerline

35、, and 25.5 mm (15 degrees) rearward of the H-Point. (See Figure 3.) 3.6.4H-POINTThe H-Point is located on an H-Point device. However, when an H-Point device is properly positioned within a vehicle either in CAD or in an actual physical property the location of the H-Point within the vehicle can be u

36、sed as a vehicle reference point. Unless otherwise noted, this is how the term H- Point is used in this practice. On an H-Point device, the H-Point is at the pivot center of the back pan and cushion pan assemblies, translated to the lateral centerline of the device. The H-Point is also the intersect

37、ion of the cushion line and the back line. (See Figure 3.) 3.6.4.1Actual H-Point, Actual H-Point Travel PathThis refers to H-Points measured in physical properties using a properly positioned H-Point machine. 3.6.4.2Design H-Point, Design H-Point Travel PathThis refers to H-Points defined during des

38、ign using an H- Point design tool and appropriate procedures. 3.6.4.3H-Point Travel PathAll possible locations of the H-Point provided by the full range of seat adjustments (horizontal, vertical or rotational) for a given designated seating position. Only seat adjustments intended for driving and ri

39、ding are included. Seat adjustments intended to facilitate entry, egress, cargo storage, etc. are excluded. 3.6.5K-POINT OR KNEE PIVOT POINTA pivot point between the thigh and lower leg segments on the H-Point devices. 3.6.6LOWER LEG LINEA line connecting the K-Point to the ankle pivot center on the

40、 H-Point devices. SAE J1100 Revised JUL2002 -5- 3.6.7SEATING REFERENCE POINT (SGRP)SgRP is a specific and unique H-Point for a given designated seating position. Although adjustable seats will have many design H-Points within their design H-Point travel path, there is one and only one H-Point define

41、d as the SgRP for any seat/seating position. The SgRP is established early in the vehicle design process. The most critical SgRP is the one defined for the driver. It is used in positioning many other design tools, defining a number of key vehicle dimensions (e.g, legroom, shoulder room, etc.), and

42、is referenced by several national and international standards and regulations. How SgRP is defined depends on the type of seat and designated seating position. a.Adjustable Seats, Driver: SgRPX = 913.7 + 0.672316(H30) 0.0019553(H30)2 mm aft of PRP. SgRPZ: If the drivers seat has a vertical adjustmen

43、t, it is preferred that the intersection of the previous SgRP equation and the mid-height point in the H-Point travel path be used. SgRPY = Centerline of occupant (at SgRPXZ) b.Adjustable Seats, Any Passenger Seating Position: SgRPXZ: Selected at the manufacturers discretion, it is any H-Point withi

44、n the design H-Point travel path. However, for the 1st row (front seat) outboard passenger, it is customary to use the X and Z location of the drivers SgRP. SgRPY = Centerline of occupant (at SgRPXZ) c.Fixed Seat, Any Designated Seating Position: Since in fixed seats there is only one H-Point possib

45、le, the SgRP is that H-Point. SgRPX = Design H-PointX SgRPZ = Design H-PointZ SgRPY = Centerline of occupant = Design H-PointY 3.6.7.1SgRP FrontThis term refers to the SgRP of the driver, unless otherwise specified. 3.6.7.2SgRP SecondThis term refers to the SgRP of the second row outboard passenger,

46、 unless otherwise specified. 3.6.7.3SgRP ThirdThis term refers to the SgRP of the third row outboard passenger, unless otherwise specified. 3.6.7.4SgRP FourthThis term refers to the SgRP of the fourth row outboard passenger, unless otherwise specified. 3.6.7.5SgRP FifthThis term refers to the SgRP o

47、f the fifth row outboard passenger, unless otherwise specified. 3.6.8SUPPORT POINTSSeat contact points on the H-Point Devices. There are five points on the cushion pan (SC1 through SC3) and four on the back pan (SB1 through SB3). The support points are used as landmarks for measuring seat dimensions

48、. 3.6.9THIGH LINEA line connecting the K-Point to the H-Point. SAE J1100 Revised JUL2002 -6- 3.7Shoe Tool Reference Points and Definitions (See SAE J826)The shoe tool is part of an H-Point device, and necessary for the proper positioning of the device within a vehicle (in CAD or in a physical proper

49、ty). 3.7.1ACCELERATOR HEEL POINT (AHP)The AHP is the intersection of the heel of shoe and the depressed floor covering, when the shoe tool is properly positioned. (Essentially, with the ball of foot contacting the lateral centerline of the undepressed accelerator pedal, while the bottom of shoe is maintained on the pedal plane). See Figure 3. 3.7.2BALL OF FOOT (BOF)A point on the shoe tool. BOF is located at the lateral centerline of the shoe, 200 mm from the heel of shoe. See Figure 3. 3.7.3BA
