Abstract
Abstract In a safety belt fastening device for a safety belt system having a belt-tightening device which acts on the fastening device of the belt and a fastening tongue which can be latched in the fastening device, whereby the fastening device comprises a fastener body having a fastening mechanism for the fastening tongue and a spring-loaded release button which acts on the fastening mechanism, it is ensured that even at the end of the belt-tightening process the operating button is within reach in an accessible position for the person who is strapped in. To this purpose, it is provided that the release button is formed in two parts with two button portions which are coupled together, which are movable in relation to each other and of which one button portion follows the movement of the fastener body during the belt-tightening process and the other button portion, after the completion of the belt-tightening process, stands in the operating position preset by the rest position of the fastener body.
