Locking web retractor with controllable lock

A locking web retractor, comprising:

• a frame having spaced-apart side walls,
• a spool including a spool shaft rotatably mounted between the side walls, the spool shaft rotatable in a web take-up direction and a web a pay-out direction opposite the web take-up direction, wherein one end of the spool shaft extends through one of the side walls and outwardly away from an outer surface thereof, and
• a locking apparatus operatively coupled to the spool shaft along the outer surface of the one of the side walls, the locking apparatus including a first toothed wheel mounted to the spool shaft so as to rotate with the spool shaft, a movable component and a first lock pawl,
• wherein the first lock pawl has an engagement end and an opposite end opposite the engagement end,
• wherein the movable component is movable between a locking position in which the movable component forces the engagement end of the first lock pawl toward and into engagement with the first toothed wheel to prevent the spool shaft from rotating in the web pay-out direction, and an unlocking position in which the movable component does not force the engagement end of the first lock pawl toward the first toothed wheel,
• and wherein the first lock pawl defines a counterweight at the opposite end thereof which is configured, in the unlocking position of the movable component in which the movable component does not force the engagement end of the first lock pawl toward the first toothed wheel, to cause the first lock pawl to move in a direction which draws the engagement end of the first lock pawl out of engagement with the first toothed wheel to allow the spool shaft to rotate in the web pay-out direction,
• wherein the locking web retractor further includes:
• at least a second toothed wheel mounted to the spool between the side walls of the frame so as to rotate with the spool shaft, and
• a second lock pawl movably mounted to and between the sidewalls of the frame, one end of the second lock pawl extending through the one of the side walls,
• and wherein the locking apparatus includes a lock pawl engagement member operatively coupled to the one end of the second lock pawl extending through the one of the side walls, the locking apparatus responsive to engagement of the engagement end of the first lock pawl with the first toothed wheel to cause the lock pawl engagement member to move the second lock pawl into engagement with the at least a second toothed wheel and to disengagement of the engagement end of the first lock pawl with the first toothed wheel to cause the lock pawl engagement member to move the second lock pawl out of engagement with the at least a second toothed wheel.
