Abstract
Abstract An installation for adjusting a safety belt hinge point in a vehicle with a slide member determining the hinge point and displaceable along a rail and with a detent mechanism selectively fixing the slide member at the rail 30 in at least two detent positions; the detent mechanism includes a detent element which engages in detent apertures of the rail and is prestressed by a spring into the detent position; the detent element and the actuating handle for the actuation of the detent element which is coupled with the detent element, are displaceable in different directions and are coupled with each other by a guide element 52 providing a step-down translation. An increased prestress force on the detent element with an actuating force for the handle that remains the same, is achieved thereby together with a mechanically simple construction.
