Abstract
The safety belt takeup device with tightening means comprises for transmitting the tightening force to the takeup shaft a rotatable roller (18) couplable to said shaft via a coupling means. At the periphery of the roller (18) the tightening force engages via a wire cable (36). In the force transmission path between the cable (36) and the takeup shaft a limiting means is provided which limits the torque which can be transmitted to the takeup shaft so that towards the end of a tightening operation no inadmissibly high tensile stresses occur in the webbing bearing on the body of the vehicle occupant.
