Abstract: An arrangement in vehicle safety belts of the three-point type for adjusting stepwise the height of the anchoring fitting located at shoulder level at one side of the seat. The arrangement comprises a fixedly mounted guide rail having U-shaped cross-sectional form and edge flanges projecting towards each other, which define a longitudinal slot and form a number of recesses distributed along the slot, and a slide which is displaceable along the guide rail and comprises an engagement element and a lock element. The engagement element is displaceable in the transverse direction of the web of the guide rail for releaseable engagement with the recesses in a desired longitudinally displaced position under spring bias with the engagement element spanning the slot between the edge flanges. The anchoring fitting is arranged on the engagement element.
