Abstract

A force-limiting device, especially for a seat belt system (10) in a vehicle, has a force transducer (20) interacting with webbing (14) for which a normal webbing path is provided. The force transducer (20) includes 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 (F) required to move the webbing (14) vis-à-vis the force transducer (20) in a direction of belt extension (R).
