Abstract
An anti-cinch automatic locking retractor. A web spool is rotatably mounted between a pair of upstanding walls. The spool includes a pair of flanges each having a plurality of locking teeth with the teeth spaced apart by an included angle. A pawl is pivotally mounted to the walls and is lockingly engagable with the teeth. A cam plate mounted adjacent the spool and rotatable therewith includes a cam surface extending through an angle greater than the teeth included angle to limit cinching of the web spool as the spool rotates to and from the locking position and through the included angle.
