23、ISO/TR 17950:2016 ISO/TR 17950:2016(E) 5 Recommendations 5.1 General It is recommended to start with the positioning of the rear outboard dummies to facilitate the placement of all dummies. 5.2 Position of the rear seats 5.2.1 Rear seats Longitudinal seat adjustment should be positioned according to
24、 the design longitudinal position for Hybrid III 5th percentile female dummy defined by car manufacturer. If no design position is available, the seat should be adjusted as close as possible to the mid-track position. Vertical seat adjustment should be positioned in the design position defined by ca
25、r manufacturer. If no design position is available, the seat should be adjusted as close as possible to the lowest position. If pitch angle can be adjusted independently, it should be adjusted according to the design position defined by car manufacturer. If no design position is available, it should
26、 be as close as possible to the mid-angled position. In absence of any manufacture specifications the default procedure should be: 1) The seat control that primarily moves the seat vertically should be used to adjust the seat reference point to the upper most vertical location. 2) The seat control t
27、hat primarily moves the seat fore-aft should be used to adjust the seat reference point defined to the rear most location. 3) The range of angles of the seat cushion pitch referring to the line and using only the control(s) that primarily adjust(s) the cushion pitch should be determined and recorded
28、, and the set cushion pitch should be as close as possible to the mid-angle. 4) The seat control that primarily moves the seat vertically should be used to adjust the seat reference point to the lowest vertical location. A verification that you are still at the rearmost seat track location should be
29、 conducted. The X position should be recorded. 5) The seat control that primarily moves the seat fore-aft to adjust the seat reference point to the forward most location should be used and the X position recorded. 6) The midpoint of X-positions recorded in 4.) and 5.) should be calculated and marked
30、. 7) The seat control that primarily moves the seat fore-aft to adjust the seat reference point to the X position marked in step 6 (0/+2 mm) should be used, or, if not possible, to the first X possible position rearward the marked position in step 6. If the seat cannot be placed exactly at the midpo
31、int the next closest available rearward setting should be selected. NOTE For some vehicles this final step changes the cushion pitch as established in step 7; this is acceptable. 8) The test seat position (for example recording the position of the reference point) should be measured and recorded. 5.
32、2.2 Rear seatbacks If adjustable, the rear seatbacks should be set at the manufacturers design position. If no design position is available and the seatback is adjustable independently from the fore-aft adjustment, the seatback should be adjusted to 25 or as close as possible.2 ISO 2016 All rights r
33、eserved PD ISO/TR 17950:2016 ISO/TR 17950:2016(E) 5.2.3 Rear head restraints The head restraint position to the vehicle manufacturers nominal design position for a 5 thpercentile adult female occupant should be set, or in the lowest locking position if no design position is available. 5.2.4 Seat sup
34、ports Any adjustable parts that provide additional support should be positioned so that they are in the lowest or fully retracted positions, e.g.: the seats adjustable lumbar supports are positioned so that the lumbar supports are in the lowest, retracted or deflated adjustment positions. 5.2.5 Seat
35、belt upper torso adjustment Any seatbelt upper torso adjustment at the vehicle manufacturers design position for the 5 thpercentile female should be placed. If no design position is specified, the seatbelt upper torso adjustment should be adjusted to the lowest vertical position. 5.2.6 Armrests If a
36、djustable, the armrests can be stowed 5.2.7 Defining the seat c entr e r efer enc e line In case of bucket seats: For future reference, the longitudinal seat center reference line of the seat cushion should be located and marked. The intersection of the vertical longitudinal plane that passes throug
37、h the SRP and the seat cushion upper surface determines the longitudinal center line of a bucket seat cushion. In case of bench seats: For future reference, the longitudinal line on the seat cushion that marks the intersection of the vertical longitudinal plane through the seat cushion upper surface
38、 and the mid seating position point should be located and marked. This is defined as: 1) designated seating transverse position defined by car manufacturer; 2) the middle of the head restraint, if size of the dummy allows it; and 3) the middle position of HIII 5 th(or SAE dummy), ensuring the best p
39、elvis alignment(minimal yaw in the most rearward position). 5.3 Design H-Point Determination 5.3.1 Determining the H-point of SAE J826 device The seat in front of the occupant can be displaced to the foremost position to facilitate access to the occupants seat. Final position of the seat in front of
40、 the occupant is based on the test protocol. 1) Using only the controls that move the seat fore-aft, the test seat should be returned to the rearmost position to facilitate placement of the SAE H-point manikin. 2) The SAE H-point manikin in the seat and position the seat to the test position for the
41、 5 thpercentile female should be placed, as defined in 6.1. 3) The procedure as described in SAE J826 should be followed, except that the length of the lower leg and thigh segments of the SAE H-point manikin should be adjusted to the 50 thpercentile (418 mm) and 10 thpercentile (408 mm) positions re
42、spectively. 4) The seat back angle should be set to achieve the torso angle specified by the manufacturer. ISO 2016 All rights reserved 3 PD ISO/TR 17950:2016 ISO/TR 17950:2016(E) 5) The H-point (of the SAE H-point manikin) X, Y and Z coordinates should be recorded. NOTE If there is not sufficient c
43、learance to permit the placement of the SAE H-point manikin legs or feet, install the manikin with the legs removed. 5.3.2 Method for deriving the Design H Points of Hybrid III 5th percentile female Dummies for rear seat position The SAE J826 anthropomorphic model with its thigh and leg lengths adju
44、sted to 408 mm and 418 mm respectively should be installed on a seat which is adjusted to the manufacturers specification for 5 thpercentile female, the positions of its H point or those of the H joint (X50M, Z50M) should be determined. The seat cushion length (“SCL”) shown in Figure 1is the distanc
45、e between the front end of the seat cushion (X Ft, Z Ft )and the SAE H-point manikins H-point (X 50M , Z 50M ). The front end of the seat cushion should be determined by drawing a perpendicular line from the manikins thigh line to the front end of the seat cushion in the vertical plane. The design H
46、 point of a Hybrid III 5 thpercentile female dummy for rear seat position is derived in accordance with the formula shown in Table 1.
