A seat belt retractor (20) has an integrally formed, quadrilaterally shaped main body portion (24), comprising a toothed lock wheel (230) and a toothed pawl lock (220) having means to flex under determinable crash loads so that the teeth of the lock pawl (220) will engage a tooth of the lock wheel (230). The frame is injection molded using 50 % by weight or greater long glass fiber plastic or die cast or injection molded metal. A spring housing wall (140) and a wall (170) of a mechanism cover are also integrally formed in the sides of the retractor. The mechanism side of the frame includes an integrally formed pin (210) to pivotally support a locking pawl (220).
