Abstract

Roll-up device for a safety belt with a mechanism for blocking the belt shaft in case of a crash. Blocking is effected by locking pawl means coupled with the belt shaft and activated by release mechanism. The belt shaft has two sets of bearings (a) the belt shaft is supported by bearings with little play and little friction and which are elastically yielding to high pull forces which occur in case of a crash, and (b) the belt shaft is simultaneously centered in stable load bearings of the basic frame with radial bearing play on all sides.
