Device for adjusting a vehicle head support and a method using such a device
First Claim
1. Device for adjusting a vehicle'"'"'s head support to the position of a passenger'"'"'s head, comprising:
- a sensor arranged in the head support to recognize the head position relative to a height of the head support, wherein the sensor contains two condenser plates arranged one over the other as part of a condenser, in which the passenger'"'"'s head acts as a dielectric;
wherein the arrangement and size of the two condenser plates is selected such that the signal emitted by both is equal when the head support is correctly set.

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.

3. Method for adjusting a vehicle'"'"'s head support, comprising the acts of:
-
starting from a rest position with the head support retracted, varying a height of the head support; and
stopping the height variation when an increase of a sensor signal of one condenser plate takes place simultaneously with a decrease of a sensor signal of another condenser plate, said one and another condenser plates being arranged one over the other in the head support as part of a condenser, in which the passenger'"'"'s head acts as a dielectric. - View Dependent Claims (4)

7. A method for adjusting a vehicle head support in relation to a passenger'"'"'s head, the method comprising the acts of:
-
seating a passenger such that the passenger'"'"'s head is in a vicinity of the head support, the head support having arranged therein two condenser plates one above the other as part of a condenser in which the passenger'"'"'s head acts as a dielectric; and
starting from a rest position with the head support retracted, varying a height of the head support at least until an increase of a sensor signal of one condenser plate takes place simultaneously with a decrease of a sensor signal of the other condenser plate. - View Dependent Claims (8, 9)
