EMERGENCY LOCKING MEANS FOR DUAL SPOOL SAFETY BELT RETRACTOR ABSTRACT A dual spool safety belt retractor having first and second ratchet means on first and second spools, respectively, is provided with an improved dual locking pawl emergency locking means including an action pawl for engaging only the ratchet wheel means of the first spool in response to actuation by inertia sensing means and reaction pawl means separate from the action pawl means for reacting in response to movement of the action pawl on its engagement with the first spool to cause locking of the second spool by the separate reaction pawl. Resilient connecting means are illustrated between the action and reaction pawl means for resiliently urging the reaction pawl into locking engagement with the ratchet wheel of the second spool in a continuing manner to overcome false locking conditions, exemplary embodiments of the resilient connecting means including a flexible linkage, a resilient rubber-like body, a leaf spring, a coil spring and a right angle loaf spring. Pawl programming means are also provided including at least a program ratchet on the first spool and a program pawl connected to the action pawl to program lockup of the action pawl to the first spool with an exemplary embodiment having a similar pawl programming means associated with the second spool and reaction pawl with a flexible linkage connecting the two program pawls.
