The seating system is probably the most underrated component of a car. A seating system can account for up to ten percent of the production costs of a car and represents the largest interface to the customer. Todays product development processes for seating systems are characterized by shortened development cycles, increasing variance, additional requirements, and rising product content in terms of functionality. This paper describes an innovative approach and the respective application-specific simulation tools intended to cope with this situation. The point of main emphasis of this paper is an innovative concept for the application of tailored simulation techniques in product development of automotive seating systems. The focus is the development of foam, trim, and covers. This concept integrates virtual and physical process segments into two control loops. The underlying process starts with a customer centered profile of objectives. These objectives are then transformed by means of transformation functions into parameters and characteristics describing the seating system. These parameters and characteristics are on the one hand used to develop the seating system using a parametric CAD system. On the other hand, these parameters and characteristics are used for validation purposes. As a result a continuous improvement cycle is achieved. This process and the tailored simulation tools allow a holistic, customer objective oriented realization of seating systems. The robustness and transparency of product development is enhanced and a capturing of knowledge is fostered. In current product development projects for seating systems components of this concept have been successfully applied. An application of the whole concept can be realized within this decade.
