Arrangement for adjusting the sitting position of a vehicle occupant

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. |

DETAILED DESCRIPTION This application claims the priority of German application 196 51 670.
6-14 filed in Germany on Dec.
12, 1996, the disclosure of which is expressly incorporated by reference herein.
The invention relates to an arrangement for adjusting the sitting position of a vehicle occupant relative to the seat, which has a seat part with a seat cushion, a backrest which is swivellably held on the back seat part and a headrest.
In the case of vehicle seats, it is known to provide a plurality of adjusting possibilities so that the vehicle occupant sitting down in the vehicle seat can assume any sitting position she or he desires.
These possibilities include longitudinally displacing the vehicle seat, adjusting the height of the seat cushion, adjusting the angle of slope of the backrest with respect to the seat cushion, and adjusting the height of the headrest.
In most cases, these adjustments can be carried out manually by the vehicle occupant using corresponding handwheels, or by using hand levers that are operated utilizing corresponding servo motors operated by hand switches.
For minimizing the danger of injury to the vehicle occupant, it is necessary in the case of certain seat components to prevent the vehicle occupant from carrying out the adjustment and implementing the adjustment automatically.
This applies particularly to the adjustment of the headrest since only its precise adjustment ensures satisfactory support of the head in an accident, thus providing sufficient protection.
In the case of a known arrangement for automatically adjusting vehicle seat components (German Patent Document DE 34 27 466 C2), a sensor provided which senses the sitting height of the vehicle occupant placed in the vehicle seat by determining the occupant's head position or shoulder position.
Corresponding to the measuring result, a control device causes an adjustment of the headrest and the belt deflection mounting of the seat belt fastened to the vehicle body to the height positions required for the sitting height
