An arrangement for step-by-step height adjustment of a holding or deflecting fitting of a seat belt on a hollow body part of a motor vehicle, particularly on a B-column or a C-column, includes a guide rail mounted on the body part, and a carriage which can be displaced along the guide rail, which can be fixed in defined adjusting positions, and which has a fastening device for the holding or deflecting fitting. The guide rail, which is arranged behind a column covering, is mountable on the vehicle body part by way of two mutually spaced fastenings. In the event of a vehicle collision, particularly a side impact, the forces acting upon a vehicle occupant's head are to be kept below a permissible limit value. Accordingly, it is provided that, in the event of a vehicle occupant's head impact onto the holding or deflecting fitting, starting from a defined force level, the guide rail and therefore the entire belt height adjusting arrangement, while absorbing energy, is laterally swivellable about an axis of rotation formed by one of two fastenings of the guide rails and extending in the transverse direction of the vehicle.
