14、81. SCOPEThe devices of this SAE Standard provide the means by which passenger compartment dimensions can be obtained using a deflected seat rather than a free seat contour as a reference for defining seating space. All definitions and dimensions used in conjunction with this document are described

15、in SAE J1100. These devices are intended only to apply to the driver side or center occupant seating spaces and are not to be construed as instruments which measure or indicate occupant capabilities or comfort. This document covers only one H-point machine installed on a seat during each test. Certi

16、fied H-point templates and machines can be purchased from:SAE International400 Commonwealth DriveWarrendale, PA 15096-0001Specific procedures are included in Appendix A for seat measurements in short- and long-coupled vehicles and in Appendix B for measurement of the driver seat cushion angle. Speci

17、fications and a calibration inspection procedure for the H-point machine are given in Appendix C. Additional considerations are necessary when a Head Restraint Measuring Device (HRMD) is mounted to an H-point machine (Appendix D).1.1 PurposeThis document specifies a two-dimensional H-point template

18、and a three-dimensional H-Point Machine (HPM) for use in defining and measuring accommodation in vehicle seats.SAE INTERNATIONAL J826 NOV2015 Page 3 of 312.

H-POINT TEMPLATE - DESCRIPTION, APPLICATION, AND POSITIONING PROCEDURE4.1 DescriptionThe H-point template (Figure 1) is constructed to represent in profile an adult male wearing shoes and corresponds to the profile of the deflected seating contour of the H-point machine. Ind

27、ividual torso, thigh, lower leg, and shoe segments are provided with locking pivot joints which can be used to fix the angular relationships of the segments. A torso angle reference bar is included to orient the templates torso in relation to the vertical.4.2 Application - Aids in displaying the fol

29、Positioning Procedure for physical template (Figure 1)4.3.1 Torso positioning for any specified Seating Reference Point and torso angle.4.3.1.1 Position the H-point of the H-point template on the Seating Reference Point (SgRP) location on the layout.1 Prior to 2008 SAE standards generally used the t

30、erm “back angle” to describe the A40 dimension of SAE J1100. New or revised standards beginning in 2008 will use the term “torso angle” for this dimension.SAE INTERNATIONAL J826 NOV2015 Page 5 of 31Figure 1 - H-Point template4.3.1.2 Set the torso angle reference bar quadrant scribe line marked on th

31、e torso angle quadrant to the specified torso angle. Lock this quadrant in place.4.3.1.3 Position the vertical reference scribe lines on the torso angle reference bar parallel to the body grid lines on the layout drawing.4.3.2 Front Seat - Driver PositionLeg and shoe positioning for any specified Ac

32、celerator Heel Point location.4.3.2.1 Holding the torso portion of the template in position as outlined in 4.3.1.1 to 4.3.1.3, position the heel point of the template at the specified heel point location. This point on the layout is located on top of the heel pad or the depressed floor covering surf

33、ace at the Y-plane centerline of the accelerator pedal.4.3.2.2 Holding the heel point at the specified location, rotate the shoe forward until the bottom of the shoe contacts the undepressed accelerator pedal without infringing upon the 87 degrees minimum ankle (foot) angle. Normally the pedal conta

34、ct point is at or below the shoe ball of foot.4.3.2.3 The undepressed accelerator pedal (point of contact with the bottom of shoe or shoe plane) may be determined by locating the heel point as described previously and presetting and locking the ankle angle to 87 degrees.4.3.3 Front Seat - Driver Pos

35、itionLeg and shoe positioning for any specified undepressed accelerator pedal location.4.3.3.1 Holding the torso portion of the template in position as outlined in 4.3.1.1 to 4.3.1.3, position the bottom of the shoe on the specified undepressed accelerator pedal and the heel as far forward as allowa

36、ble. However, the ankle angle is never less than 87 degrees. Lock ankle angle quadrant.SAE INTERNATIONAL J826 NOV2015 Page 6 of 314.3.4 Second Row - Left Side Occupant PositionLeg and shoe positioning with the front seat in its SgRP position.4.3.4.1 Holding the torso portion of the template in posit

37、ion as outlined in 4.3.1.1 to 4.3.1.3, except with the template H-point on the SgRP of the second row seat, place the bottom of the shoe (heel and ball) on the depressed floor covering line. The shoe is to be placed on the Y-plane centerline of the occupant or up to 127 mm (5 in) on either side of t

38、he Y-plane centerline on the floor pan section.NOTE: Locating the shoe either side of the Y-plane centerline of the occupant position will make the shoe location compatible to the shoe location in the existing H-point machine installation procedure.4.3.4.2 Move the shoe forward along the depressed f

39、loor covering line to the nearest interference of the toe, instep, lower leg, or knee with the front seat. The ankle angle is to be restricted to a maximum of 130 degrees.4.3.5 Third Row - Left Side Occupant Position - Forward Facing4.3.5.1 Follow the procedure as outlined for the second row seat, l

40、eft side occupant position except that the template is positioned in the third seat compartment.4.3.6 Third Row - Left Side Occupant Position - Rearward Facing4.3.6.1 Follow the same procedure as outlined for the third row - side occupant position - forward facing except that the shoe is positioned

41、in the footwell to the interference with the rear end or closure.4.3.7 H-point template layout using data obtained during H-point machine installation.4.3.7.1 Position the H-point pivot of the template at the measured H-point location on a layout drawing or grid system.4.3.7.2 Follow the procedure a

42、s outlined in 4.3.1.1 to 4.3.1.3 using the measured torso angle instead of the design torso angle.4.3.7.3 Holding the torso portion of the template in position as outlined previously, move the upper leg segment to the measured hip angle shown on the hip angle quadrant.4.3.7.4 Lock this quadrant in p

43、lace.4.3.7.5 Position and lock the ankle (foot) angle quadrant to the measured ankle angle.4.3.7.6 Allowing the knee angle to vary as necessary, position the ankle pivot center on an arc from the hip pivot center equal to the measured effective leg room less 254 mm.4.4 Positioning Procedure for CAD

44、template (Figure 2)4.4.1 Use of optional shoe bottom4.4.1.1 The standard H-point template has a shoe with an arched bottom and a defined heel shape. The BOF point on the shoe is 203 mm (8 in) from the heel of the shoe. SAE manikins defined in SAE J4002 (HPM-II) and SAE J4004 (HPD) have a shoe with a

45、 flat shoe bottom from the shoe heel to the BOF. There is no heel pocket. As an option to aid in transitioning to these devices, users are strongly encouraged to flatten the shoe bottom of the CAD template, as shown in Figure 2.SAE INTERNATIONAL J826 NOV2015 Page 7 of 314.4.2 Positioning for any spe

46、cified Seating Reference Point and torso angle. 4.4.2.1 Position the H-point of the CAD template on the SgRP at the specified torso angle. Use values for SgRP and torso angle that are either specified by the manufacturer or can be determined from SAE J4004.4.4.2.2 For the driver position, lock the a

47、nkle angle at 87 degrees. The bottom of the shoe should be touching the undepressed accelerator pedal. Alternatively, the heel of shoe may be placed at the manufacturer AHP with the bottom of the shoe touching the pedal.Figure 2 - CAD version of h-point template4.4.2.3 For passenger positions the sh

48、oe should be positioned with the heel of shoe at the floor reference point (FRP) and the bottom of shoe on the floor. 4.4.3 Positioning for an unknown Seating Reference Point and torso angle. 4.4.3.1 Install the 3-D H-point machine to determine the seat H-point travel path. See SAE J1100 for determi
