Abstract: A height adjusting mechanism for an upper brace of a shoulder belt of a safety belt device of a motorized vehicle has a locking device that includes a guide track having a longitudinal extension and having locking recesses distributed along the longitudinal extension. The locking device also includes a slide displaceable in the longitudinal direction and a locking lever with a locking projection. The locking lever has a supporting zone for supporting the locking lever on the slide such that the locking lever is pivotable from a locking position into a release position. In the locking position the locking projection engages one of the locking recesses. The locking lever has a zone of reduced material strength located between the locking projection and the supporting zone, wherein the zone of reduced material strength provides a deformative travel for the locking projection under load and has an abutment for limiting the deformative travel.

Abstract: A buckle for safety belts, especially in motor vehicles. The buckle has a housing and a tongue which can be inserted in an opening of the latter, can be locked in the housing by at least one latching member, and is stressed by a spring-loaded ejector. To be prevented is the technical of the rattling against one another of the housing and the buckle tongue. For this purpose, at least one spring element is disposed in the housing in the vicinity of the insertion opening for the buckle tongue. At least one abutment surface of the spring element projects laterally into the path which is to be traversed by the buckle tongue upon insertion in such a way that the tongue is acted upon transverse to the direction of insertion or ejection.
