Abstract
A belt retractor for a vehicular seat belt comprises a belt reel rotatably mounted in a frame, two locking discs for blocking the belt reel and two energy absorbing elements. The energy absorbing elements are each connected at an axial end to a locking disc and one of which is non-rotatably connected at an axial end to the belt reel. The belt retractor further comprises two locking pawls that are capable of cooperating with the locking discs. At least one of said locking pawls is releasably connected in a starting position to the frame by a connecting element.
