ABSTRACT:
A force limiter for vehicle safety belt systems which is inserted in the force flow path of the safety belt system by means of two fittings (26, 32), the distance between the fittings (26, 32) being able to be increased with a conversion of energy. In the context of such a force limiter the characteristic of the tensile force effective between the two fittings is to be rendered adjustable along the deformation displacement over a wide range. This is achieved since a first one (26) of such fittings is fixedly connected with the metal frame (20) having a deflection pin (22) arranged therein and a second one (32) of the fittings is fixedly connected with a first end of a metal strip (30), which is adapted to be drawn about the pin (22) along a positively set path. Owing to such configuration it is possible for the characteristic of the force limiter to be selected by the designer within a wide range independently of the threshold value as from which the force limiter takes effect.
