Abstract
A safety belt reel-in mechanism having a tensioning arrangement. A piston is provided which is acted upon by pressure medium, and which is disposed at a distance relative to the belt reeling-in shaft of the belt reel-in mechanism, and can by connected with this shaft via a cable drive when the tensioning arrangement is triggered. The problem of heretofore known devices was that after the tensioning arrangement was triggered and the tensioning process was terminated, the belt reeling-in shaft was locked into position via the tensioning arrangement, and hence could no longer function as intended. To eliminate the resulting drawback that, after the tensioning arrangement is triggered, the belt reel-in mechanism no longer has a self-locking action, the present invention proposes disposing a spring-loaded locking member on the cable pulley which receives the drive cable. The locking member is adapted to engage appropriate elements on the belt reeling-in shaft to operatively connect this shaft and the cable pulley. This connection is disconnected after termination of the tensioning process.
