Title:
【発明の名称】荷重下で変形する弾性座席クッションにおける表面輪郭を検出する方法とその装置
Document Type and Number:
Japanese Patent JP3096433
Kind Code:
B2
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.
