Force-limiting device and seat belt system

A force-limiting device for a seat belt system (10) in a vehicle, comprising a force transducer (20) interacting with webbing (14) for which a normal webbing path is provided, wherein the force-transducing member (20) has a webbing track (30) that in a non-force-limiting position extends in parallel to the normal webbing path and in a force-limiting position extends inclined relative to the normal webbing path so that the force transducer (20) in the force-limiting position sets a predetermined extension force required for moving the webbing (14) vis-à-vis the force transducer (20) in a direction of webbing extension (R), wherein the force transducer (20) has at least two movable parts (22) which have a substantially identical structure and which are disposed in series in the webbing extension direction (R), and wherein at each movable part (22) at least a portion of the webbing track (30) is configured, the movable parts being rotatable or pivotable about an axis of rotation (A) to the force-limiting position, and wherein the axis of rotation (A) is aligned to the direction of webbing extension (R) and in parallel to a surface area of the webbing (14).
