ABSTRACT:
A bearing for the rotatable mounting of a control disc in an automatic safety belt retractor is disclosed. The relative rotation between the belt reel and the control disc activates an emergency blocking mechanism. In order to reduce the axial dimension of the control disc, the bearing comprises a bearing journal inserted into a central bearing opening of a hub of the control disc, and one of the axial ends of the opening is widened to receive an insert having a bearing bore receiving the adjacent axial end of the bearing journal. The bearing journal has a radial shoulder and the insert has detent elements engaging behind the radial shoulder.
