Along with the definition of a new vehicle's interior dimensions, the Seating Reference Point (SgRP) is determined. The SgRP defines the position of the occupant in the vehicle. The seats consequently have to be developed in a way that the H-point of the seat is located within a tolerance around the SgRP.
Our H-point simulation methodology allows for this situation to be analyzed during the virtual development phase. For this purpose the seat model from the static comfort simulation is combined with a model of the H-point measuring manikin according to SAE J826.
Deviating only a few millimeters, the prognoses resulting for the H-point are very close to the measured values of future prototypes.
