Abstract

In a device for adjusting a vehicle's head support with reference to the position of a passenger's head, with a sensor disposed in the head support for detecting the position of the head, the sensor contains two condenser plates which are arranged one above the other and are part of a condenser, in which the head of the passenger acts as a dielectric. In the method for the adjustment of the vehicle's head support, the height is varied, starting from a rest position with the head support retracted, to such an extent that the increase of the sensor signal of the one condenser plate takes place simultaneously with the decrease of the sensor signal of the other condenser plate.
