  "textContent": "A seat belt retractor (20) has both ELR and ALR modes of operation. The seat belt retractor (20) has a sensor pawl (44) movable between a released and a locked position with teeth (34) of a ratchet wheel (46) rotatable with a spool (24). The sensor pawl (44) is part of both the ELR and ALR locking mechanisms. A spring biased lever (130) is rotatable to a first position and when in the first position urges the sensor pawl (44) toward engagement with the ratchet wheel (46). The lever (130) is movable to a second position, which permits the sensor pawl (44) to move away from the ratchet wheel teeth (34) to prevent the seat belt retractor (20) from entering into the ALR mode of operation. The lever (130), when in the second position, biases the sensor pawl (44) into engagement with a cooperating inertial mass (42) that is part of a vehicle sensitive locking mechanism of the seat belt retractor (20). This bias force operative on the sensor pawl (44) is effective to limit the motion of the inertial mass (42) to lessen or eliminate vibrational movement of the inertial mass (42) relative to the sensor pawl (44) and movement relative to a support basket or support structure that holds the inertial mass (42) thereby lessening acoustic and vibrational noise created by the movement and rattling of the sensor pawl (44) and/or inertial mass (42).",
