Abstract:
In a safety belt winding device having a tensioning mechanism that acts on a belt winding shaft and that is provided with a drive means, wherein upon initiation said tensioning mechanism is adapted to be coupled via a tensioner coupling with said belt winding shaft, said belt winding device furthermore being provided with a force-limiting device for a predetermined belt withdrawal, wherein a connection between said belt winding shaft and said tensioning mechanism is adapted to be eliminated after conclusion of a tensioning movement acting in a winding direction of a belt, and wherein said tensioning mechanism has a driving cable that is adapted to be unwound from a cable pulley that is adapted to be coupled to said belt winding shaft,the improvement wherein said cable pulley is accommodated in a housing, wherein a retaining element is disposed on an end of said cable and is releasably fixed in position on said pulley, wherein an ejection arm is mounted on said pulley such that it can be pivoted out radially and that during a tensioning process in a belt winding direction is held in a pivoted-in position by said housing, whereupon during rotation of said belt winding shaft in a belt withdrawal direction, said ejection arm pivots outwardly and is fixed from further rotation via a configuration of said housing and thereby displaces said retainer element of said cable out of an engagement with said pulley.
