Abstract
A self-locking belt reeling mechanism for buckle-on safety belts, particularly safety belts in motor vehicles. The mechanism has a spindle which is mounted in a housing, is subjected to spring tension, and on which the belt can be rolled up, and an inertial locking member which is eccentrically mounted on one end of the spindle and which, in the event of a predetermined acceleration in the rotation of the spindle in the direction of unrolling of the belt, moves outwards and makes contact with stops in the form of a ring of teeth integral with the housing. The locking member has a curved recess with at least one further stop, into which recess engages an attachment provided on the end of the spindle. This attachment acts as a stop for the locking member during any relative movement between the spindle and the locking member. The eccentric point for the eccentric mounting of the locking member is arranged at least on the circumferential line of the spindle, preferably outside this line. The attachment provided on the end of the spindle, and the locking member mounted thereon with its curved recess, have guide surfaces which are portions of circles drawn about the eccentric point, so …
