ABSTRACT:
Safety belt roll-up device with a mechanism for blocking the belt roller in case of danger. A control disc rotatably supported on the belt shaft moves when activated by a vehicle-and/or belt-sensitive sensor arrangement relative to the roller shaft. A control pawl is eccentrically and hingeably supported at the roller shaft. The control pawl at the occurrence of the mentioned relative motion is moved by the control disc against the force of a spring, and is coupled with a control part which effects the engagement of a locking lever in locking teeth. The control pawl and the control disc can be coupled to each other by a drive-projection, which is arranged in the immediate vicinity of the control pawl-tilt axis at one of these parts, and extends into the motion path of the other part.
