Abstract
A self-locking safety belt device has a housing and a reeling shaft rotatably mounted therein. A vehicle-sensitive control system including a control disc acts on a locking member for locking rotation of the reeling shaft when the vehicle sensitive control system is activated. A control device including a switching lever acts on the control disc such that in a release position the switching lever is disengaged from the control disc so that the control disc rotates freely with the reeling shaft. In a locking position the switching lever secures the control disc against rotation and initiates locking of the reeling shaft. The control device has first and second gear wheels with a switching cam. The first gear wheel is connected to the reeling shaft. The second gear wheel is spaced at a distance from the first gear wheel and is rotatably mounted at the housing. The control device also has a crown gear enclosing and meshing with the first and second gear wheels. The crown gear is slidably mounted at the housing. The switching cams of the first and second gear wheels cooperate with a switching cam of the crown gear to move the crown gear between two control positions for controlling the…
