WorldSID Seating Procedure Draft 5.4
1.0 seat preparation
1.1 Adjustments
a) Position the test seat’s adjustable lumbar supports so that the lumbar supports are in the lowest, retracted or deflated adjustment positions.
b) Position any adjustable parts of the seat that provide additional support so that they are in the lowest or most open adjustment position.
c) Position an adjustable seat cushion length to the retracted position.
d) Position an adjustable leg support system in its rearmost position.
e) Place adjustable pedals in the full forward position (towards the front of the vehicle.)
f) Set the steering wheel hub at the geometric center of the full range of driving positions including any telescoping positions.
g) Set the head restraint position to the vehicle manufacturer’s nominal design position for a 50th percentile adult male occupant.
h) Place any adjustable seat belt anchorages at the vehicle manufacturer’s nominal design position for a 50th percentile adult male occupant.
1.2 Seat markings
a) Define seat cushion reference points:
Identify one seat cushion reference point at the front and one at the rear side of the seat cushion. Draw a line through the seat cushion reference points.
b) Define seat centerline reference.
Bucket seats:
Locate and mark for future reference the longitudinal centerline of the seat cushion. The intersection of the vertical longitudinal plane that passes through the SRP and the seat cushion upper surface determines the longitudinal centerline of a bucket seat cushion.
Bench seats
Locate and mark for future reference the longitudinal line on the seat cushion that marks the intersection of the vertical longitudinal plane through the centerline of the steering wheel and the seat cushion upper surface.
1.3 Starting Seat position
1. Use the seat control that primarily moves the seat vertically to adjust the rearmost seat reference point defined in 1.2(a) to the upper most vertical location;
2. Use
