SAFETY BELT WINDING UP ASSEMBLY FOR SAFETY BELT SYSTEMS USED IN VEHICLES

摘要

The invention relates to a belt retractor for safety belt restraining systems in vehicles, having a helical retraction spring (16) which has a radially internal spring connection to the shaft (12) of the belt reel and a radially external spring connection to a connecting part (18) which is fixed to the casing. A cylindrical part (141) of a cartridge (14) surrounds the retraction spring (16). According to the invention, the shaft (12) is arranged, together with the internal spring connection, eccentrically with respect to the cylindrical part (141) of the cartridge (14) in such a way that when the belt is wound up, the outside circumference of the retraction spring (16) is situated in the cylindrical part (141) of the cartridge (14) in an essentially concentric manner.
