Abstract
An arrangement for adjusting the sitting position of a vehicle occupant has a sensor which determines the sitting height of the vehicle occupant sitting in the vehicle seat and measures in a no-contact manner, a control unit connected with the sensor, and an adjusting motor for the headrest which is connected with the control unit. For reducing the adjusting efforts required of the vehicle occupant when the seat is used and simultaneously ensuring a precise support of the cervical spine by the headrest which is individually adapted to the vehicle occupant, another adjusting motor for a vertical adjustment of the seat cushion relative to the backrest is provided which is also controlled by the control unit. The sensor scans the contour of the vehicle occupant's cervical spine and a computer integrated in the control unit computes from the scanning signals of the sensor the required height position of the headrest. A control logic integrated in the control unit first causes a controlling of the seat cushion adjusting motor and then a controlling of the headrest adjusting motor.
