ABSTRACT:
In the device for limiting the belt forces generated in cases of restraint in safety belts of vehicles described in the specification, a band-shaped component is provided with a longitudinal slot and a bolt-shaped widening body is engaged in the longitudinal slot. The widening body is wider than the slot so that, if a predetermined belt force is exceeded, relative displacement between the component and the widening body will occur, causing widening of the component. In order to maintain the belt force level required for widening as constant as possible along the displacement path, a shaping body acts on the component to restore its shape after widening. The shaping body has two cutting-edge-like wings aligned essentially at right angles to the plane of the component, the wings being arranged to act on the opposite longitudinal sides of the component at an acute angle with respect to the direction of the force applied to the device.
