ABSTRACT:
A belt force limiter for a vehicle seat belt is mounted fixed to the vehicle by one end and, at its opposite free end, secures the shoulder strap approximately at shoulder level. The shoulder strap is displaced forward in relation to the vehicle seat with a limited amount of travel by the belt force limiter when tensile loading occurs due to a crash, tensile energy being absorbed in the belt force limiter. The belt force limiter has a pivot lever which is linked to an energy-absorbing component and in the position of rest is aligned approximately vertically and whose free end can be pivoted forward by the tension on the shoulder strap in the event of a crash, as a result of which the energy-absorbing component is deformed in an energy-absorbing manner.
