Abstract
Abstract An arrangement for adjusting the position of a vehicle seat backrest from upright to lying-down position is combined with an arrangement for limiting such tilting, for example to a position in which the backrest is tilted from the upright position by only 30*, in dependence upon the operational condition of the vehicle. The limiting arrangement may be controlled by application or release of the safety belts, for limiting the tilting angle of the backrest when the belts are applied.
