Abstract
The invention relates to a belt retractor for vehicular seat belt restraining systems having a spiral retraction spring (16) including a radially inner spring connection on the shaft (12) of the belt reel and a radially outer spring connection on a connecting part (18) firmly connected to the frame. A cylindrical part (141) of a cassette (14) surrounds the retraction spring (16). According to the invention the shaft (12) with the inner spring connection is eccentrically disposed with respect to the cylindrical part (141) of the cassette (14) in such a manner that, when the belt webbing is fully coiled, the outer circumference of the retraction spring (16) is disposed substantially concentrically in the cylindrical part (141) of the cassette (14).
