ABSTRACT:
The invention concerns an arrangement for adjusting the seat back inclination of a seat into an optimum individual inclination position without manipulation or motor aids, which is characterised in that it comprises a sensor system for ascertaining the weight of the user of the seat and transfer of the result to a resilient element by way of which the sensor system result is transmitted to the seat back limbs.
