摘要

Vehicle seat (1) comprises a seat cushion (3), a backrest cushion and a head restraint cushion made from a hollow body of flexible material and filled with a loose material and/or fluid. The filling can be redistributed by applying a magnetic or electrical field, by applying an electric current, by heating or by hydraulically exciting to change the shape of the cushions. Preferred Features: The hollow body contains a ferromagnetic filler material which can attract or repel magnetic fields or contains a magneto- or electro-rheological filling. The seat cushion, backrest cushion and/or head restraint cushion are made from several hollow bodies joined together.
