Abstract
Method of controlling at least one active headrest in a vehicle. The invention relates to a method of controlling an active headrest in a vehicle, in which the active headrest is triggered when predeterminable triggering conditions indicative of a vehicle collision exist, comprising the exceeding of a predeterminable collision threshold value by a characteristic variable indicative of a collision. According to the invention, the driving status of the vehicle is monitored for the presence of a reversing status and, if a predeterminable reversing status exists, the triggering of the active headrest is blocked or the collision threshold value is raised from an otherwise applicable normal value to a predeterminable maneuvering tolerance value, or the vehicle speed is sensed and the approach speed of objects approaching the rear of the vehicle is sensed, by an approach sensor system, and, if in reverse, the triggering of the active headrest is blocked or the collision threshold value is raised from an otherwise applicable normal value to a predeterminable maneuvering tolerance value if the sensed approach speed of objects approaching the vehicle lies below a predeterminable approach speed threshold.
