ABSTRACT:
A tandem dual spool retractor structure having a common frame and non-aligned separate spools with a common sensor acting on non-aligned pawls and where the pivotal actuator is free to rise in slots so as to prevent either spool from blocking the locking of the other spool. The spools are both supported by flanges formed from the one-piece frame. The spools are journalled in flexible plastic brackets which also support the pawl elements and the pawl elements, on lock-up, flex to buttress relation with the frame elements and force transmitting elements are provided on the inboard bearings which supplement the strength of the central or inboard supports.
