摘要

The system (10) has a seat cushion (12) and a backrest (14), where a warning element i.e. heating element, is integrated in the system based on a signal indicating hazard situation and a seat unit indicates hazard situation to a seat occupant. Pressing force is produced by the warning element on the seat occupant for referring the seat occupant on the hazard situation. The temperature of the heating element is varied depending on the seat occupant during hazard situation. An independent claim is also included for a method for operating a cushion and a seat back.
