Longitudinal seat adjustment should be positioned according to 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 car 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 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 that 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, 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 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.
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 midpoint 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.ISO TR 17950 pdf free.
