ABSTRACT:
Mechanism in roll-up devices for safety belts in motor vehicles, where the safety belt which, addressed by one or more danger sensors, can be blocked via a belt shaft, is stressed in tension by a spring force in the winding-up direction of the belt shaft, and where, within a short range of rotation of the belt shaft in the pull direction of the safety belt, a locking device for the belt shaft, acting against the elastic winding-up spring force, is made effective by control gates of plate cams. The locking wheel of the locking device, connected to the belt shaft secured against rotation is arranged within a first ring-shaped plate cam which can be swung freely between two stops within a recess and is equipped with a control recess within a control gate. The first plate cam is in frictional contact via a friction element with a second plate cam which is arranged axially next to the first plate cam and the locking wheel. The second plate cam can be swund freely between stops of the first plate can and is equipped with a control recess within a control gate. A fixed counter-supported locking pawl is guided with elastic contact at the circular control gates of the two plate cams, out of engagement with the locking wheel. The locking pawl engages and blocks the locking wheel if the control recesses are simultaneously opposite each other.
