Abstract:
A force limiter for a seat belt retractor comprising a frame, a belt reel rotatably mounted in said frame and a drum which may be coupled with said belt reel for joint rotation, and a plastically deformable metal band that may be wound on said drum with dissipation of energy, said metal band running through a plurality of deflection elements arranged on said frame to be deformed thereby, wherein at least one of said deflection elements is supported on a supporting structure fixed to said frame and is arranged on said frame so as to be movable transversely to said metal band, said deflection element being provided with a stepped contact surface area for a correspondingly stepped abutment surface area on said supporting structure, whereby, when said supporting structure engages a step of said contact surface area, a retraction movement of said deflection element relative to said metal band is permitted.
