Abstract

A seat belt retractor comprising: a first and a second energy absorption mechanism each of which is selectively activatable and respectively configured to generate first and second levels of energy absorption and when activated define an output characteristic of the retractor; a switch mechanism for operatively selecting one or the other energy level and a mode shifter for shifting between the first energy absorption level and the second energy absorption level as a function of the rotation of a spool of the retractor.
