ABSTRACT:
A method and a device for determining the surface contour of an elastic seat cushion deformable under load are provided. Through the use of a measuring mat placed on the seat cushion, after the load is relieved, the resultant deformed state corresponding to the deformed surface of the cushion is preserved by applying a vacuum to the measuring mat. The three-dimensional surface contour of the measuring mat fixed in its deformed state is measured with a multicoordinate measuring device in known fashion. The measuring mat consists of two vacuum-tight material webs, especially plastic films, connected vacuum-tight with one another to form a pocket having a vacuum connection, with the pocket being filled with a granulate, preferably a foam granulate.
