1. A process for producing a supporting shell for a seat having at least one pad, which supporting shell forms a supporting substructure for at least one of a seating surface and a backrest of the seat, the process comprising the acts of:

  • a) providing a measuring mat on a seat frame comprising a planar, non-cushioned contact surface in a region of the seating surface and/or backrest, the measuring mat being flexible in space;

    b) seating a test subject down on the measuring mat, and fixing in place a three-dimensional surface contour of the measuring mat produced by the act of sitting down;

    c) determining geometric data of the three-dimensional surface contour of the measuring mat;

    d) releasing the fixed three-dimensional surface contour of the measuring mat;

    e) repeating the acts of seating, determining and releasing with different test subjects; and

    f) superimposing the three-dimensional surface contours resulting from the measurements carried out with different test subjects onto each other, and deriving the three-dimensional surface contour of the supporting shell therefrom.
