ABSTRACT:
An emergency locking dual spool safety belt retractor having a frame, two belt storage spools rotatably mounted in said frame, a spool locking ratchet on each spool and an inertia sensor for sensing vehicle acceleration or deceleration above a predetermined value is provided with a split pawl locking means for locking the two belt storage spools in response to operation of the inertia sensor wherein resilient means are provided, including a pawl guide positioning the pawl members and cushioning them between the spool ratchets and resilient bushings surrounding ends of the pawl members and guide which penetrate the retractor frame side walls, whereby lockup of both spools by the two separate pawl members is assured even in a false latching condition and when one or the other pawl member engages a ratchet in a tooth to tooth condition, the resiliency of the resilient guide and bushings cooperating to maintain the pawl members in spool locking condition in response to operation of the inertia sensor.
