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.

Abstract: A motor-vehicle seat is disclosed with a spring core resting on a subframe and surrounded by a topframe, each topframe portion pointed in the longitudinal direction of the vehicle being supported relative to the subframe via a stay preventing floating movements and limiting lateral compression movements. In order to allow retrofitting and to prevent reactions on the topframe under compression movements the stay consists respectively of a foam block which is fixed to the subframe and which is inserted between two springs stretched from the subframe to the topframe and at least partially surrounds these positively.
